1. Ingeniaritza Plastikoen Industriaren eta Core Performance Ezaugarrien ikuspegi orokorra

1.1 Ingeniaritza Plastikoen Industriaren egungo egoera eta garapen joera

Ingeniaritza plastikoak egiturazko material gisa erabil daitezkeen eta tenperatura-tarte zabalean karga mekanikoak jasaten dituzten material plastikoen klaseari erreferentzia egiten diote.. Plastiko orokorrekin alderatuta (hala nola, polietilenozko PE, polipropilenozko PP, PVC polibinilo kloruroa), ingeniaritza plastikoek errendimendu integral bikaina dute, eta industria-ekoizpenean eta goi-mailako produktuen fabrikazioan erabilera eskakizun gogorrak bete ditzake. Azken urteotan, Beheko industriaren hobekuntzak bultzatuta, hala nola automobilgintza arina, electrical and electronic intelligence, and medical device high-endization, the global engineering plastics market has shown a steady and rapid growth trend.

According to relevant industry data, the global engineering plastics market size has exceeded 100 billion US dollars, and it is expected to maintain a compound annual growth rate of 7%-10% in the next five years. Among them, Asia-Pacific is the world’s largest engineering plastics production and consumption market, accounting for more than 55% of the global market share, mainly due to the rapid development of automotive, electrical and electronic industries in China, India and other countries, as well as the continuous improvement of industrial supporting capacity and technological innovation level. Txina, as the world’s largest engineering plastics consumer and producer, has a huge market demand, and the annual output and consumption are growing at a double-digit rate, especially in the fields of new energy vehicles, 5G communications, eta gailu medikoak, the demand for high-performance engineering plastics is showing an explosive growth trend.

The development trend of the engineering plastics industry is mainly reflected in five aspects: first, high performance and functionalization. With the continuous improvement of use requirements in downstream fields, engineering plastics are developing towards higher heat resistance, higher strength, better wear resistance and special functions (hala nola, suaren erresistentzia, antistatic, antibacterial, radiation resistance), to adapt to the harsh working environment of high temperature, high pressure, corrosion and radiation; second, lightweight and integration. In the automotive, aerospace and other fields, in order to achieve energy saving and emission reduction goals, engineering plastics are increasingly used to replace metal materials, and the integration of product design is becoming higher and higher, which can reduce the number of parts, simplify the production process and reduce costs; third, environmental protection and recyclability. With the strengthening of global environmental protection policies and the improvement of environmental protection awareness, the development and application of recyclable engineering plastics, biodegradable engineering plastics and environmentally friendly processing technologies have become the focus of the industry, reducing environmental pollution caused by plastic waste; fourth, intelligence and precision of processing equipment. Engineering plastics have high processing difficulty and strict quality requirements, which put forward higher requirements on processing equipment. Intelligent, precise and efficient twin-screw extruders and automatic production lines have become the mainstream of the industry, realizing real-time monitoring, automatic parameter adjustment and predictive maintenance of the processing process; fifth, diversification of application fields. Engineering plastics are gradually expanding from traditional automotive, electrical and electronic fields to new energy, medikoa, aeroespaziala, construction and other emerging fields, opening up new market space.

Aurrekari honen aurrean, twin-screw extrusion technology, as the core processing technology of engineering plastic compounds, has become the key to improving the competitiveness of engineering plastics enterprises. Ingeniaritza plastikoak gehiegizko berotzearen eta degradazio hidrolitikoarekiko sentikorrak dira, eta prozesatzeko tenperaturan baldintza handiak dituzte, ebakidura-indarra, egoitza-denbora eta tenperatura kontrolatzeko zehaztasuna. Gure HTS serieko estrusoreak ingeniaritza plastikoen prozesatzeko ezaugarrietarako bereziki diseinatuta daude, pare handiarekin, abiadura handikoa, tenperatura kontrol zehatza eta sakabanaketa bikaina, horrek ingeniaritza plastikoen prozesatzeko zailtasunak modu eraginkorrean konpon ditzake eta enpresei kalitate handia lortzen laguntzen die, ekoizpen eraginkorra eta egonkorra.

1.2 Ingeniaritza plastikoen oinarrizko errendimenduaren ezaugarriak

Plastiko eta metalezko material orokorrekin alderatuta, ingeniaritza plastikoek errendimendu integral paregabea dute, horrek hainbat industria-eremutan duten aplikazio zabala zehazten du. The core performance characteristics of engineering plastics are mainly reflected in the following five aspects, which also put forward special requirements for their processing technology and equipment:

1.2.1 Excellent Heat Resistance and Cold Resistance

Engineering plastics have a wide temperature adaptation range, which can maintain good mechanical properties (indarra, toughness, gogortasuna) in both high and low temperature environments. Plastiko orokorrekin alderatuta, which usually lose their mechanical properties at 80-120℃, most engineering plastics can work stably at 100-250℃, and some special engineering plastics (such as PEEK, PI) can even work at temperatures above 300℃. Aldi berean, engineering plastics also have good cold resistance, which can maintain good toughness at low temperatures (below -40℃), and are not easy to brittle fracture. Errendimendu horri esker, ingeniaritza-plastikoak egokiak dira tenperatura-ingurune gogorretan erabiltzeko, hala nola, automobilgintzako motorraren piezak (tenperatura altua) eta kanpoko ekipamendu elektrikoa (tenperatura baxua).

Ingeniaritza plastikoen bero-erresistentzia bikaina batez ere egitura molekular bereziari zor zaio (hala nola, eraztun aromatikoak, eraztun heteroziklikoak) eta molekulen arteko indar indartsuak, eta horrek ez ditu erraz urtzen eta deskonposatzen tenperatura altuetan. Hala ere, horrek ere zenbait zailtasun dakartza prozesatzeko: prozesatzeko tenperatura handiagoa behar da urtu eta plastifikatzeko, eta tenperatura kontrol zehatza behar da deskonposizio termikoa saihesteko.

1.2.2 Korrosioarekiko erresistentzia eta iraunkortasun ona

Ingeniaritza plastikoek egonkortasun kimiko eta korrosioarekiko erresistentzia bikaina dute, eta ez dira errazak azidoek herdoiltzen, alkaliak, gatzak, organic solvents and other chemicals. Compared with metal materials, which are easy to rust and corrode, engineering plastics have longer service life in harsh chemical environments. Adibidez, poliamida (PA) engineering plastics are resistant to most organic solvents and weak acids and alkalis; polikarbonatoa (PCa) engineering plastics are resistant to corrosion by non-oxidizing acids and salts; polyphenylene sulfide (PPS) engineering plastics are resistant to corrosion by almost all chemicals except strong oxidizing acids.

In addition, engineering plastics have good weather resistance and aging resistance, and are not easy to degrade and age under the action of sunlight, rain, oxygen and other environmental factors, which ensures their long-term stable use in outdoor and harsh environments. This performance makes engineering plastics widely used in chemical equipment, kanpoko ekipamendu elektrikoa, automozioko kanpoko piezak eta beste arlo batzuk.

1.2.3 Prozesatzeko erraza eta produkzio-eraginkortasun handia

Compared with metal materials, ingeniaritza plastikoek prozesatzeko errazaren abantailak dituzte, ekoizpen-prozesu sinplea eta ekoizpen-eraginkortasun handia. Metalezko materialek normalean prozesatzeko prozedura konplexuak behar dituzte, hala nola forjaketa, galdaketa, mekanizazioa, energia-kontsumo handia dutenak, eraginkortasun baxua eta kostu handia; ingeniaritza plastikoak, berriz, estrusio bidez prozesatu daitezke, injekzio-moldaketa, putz moldatzea eta beste metodo batzuk, masa ekoizpena gauzatu daitekeena, ekoizpen-prozesua erraztu, energia kontsumoa eta ekoizpen kostua murriztea. Adibidez, ingeniaritza plastikozko automozio pieza baten prozesatze-zikloa injekzio bidezko segundo gutxi batzuetatik hamarka segundo baino ez da., pieza metaliko beraren prozesatze-zikloak, berriz, hainbat ordu edo hainbat egun iraun dezake.

Hala ere, engineering plastics also have certain processing difficulties: they are sensitive to overheating and hydrolytic degradation, and are easy to decompose if the processing temperature is too high or the residence time is too long; aldi berean, ingeniaritza plastiko batzuk (hala nola, PA) have high water absorption, which affects the processing effect and product quality. Horregatik, it is necessary to use professional processing equipment and scientific processing techniques to ensure the processing quality.

1.2.4 Excellent Dimensional Stability and Electrical Insulation

Engineering plastics have good dimensional stability, and the shrinkage rate is small (usually 0.3%-1.5%) during processing and use, which can ensure the dimensional accuracy of products and avoid deformation. This performance is particularly important for high-precision parts, such as electrical connectors, automotive precision components, gailu medikoak, etab. The good dimensional stability of engineering plastics is mainly due to their high crystallinity, low water absorption (except for some varieties such as PA) eta molekulen arteko indar indartsuak.

In addition, most engineering plastics have excellent electrical insulation performance, which can maintain good insulation performance in a wide temperature range and frequency range, and are not easy to conduct electricity and arc. This makes engineering plastics widely used in electrical and electronic fields, such as wiring boards, cable ties, connectors, relays, motors and other electrical components.

1.2.5 Light Weight and High Specific Strength, Outstanding Wear Resistance

Engineering plastics have the characteristics of light weight (density is 1/3-1/5 of metal materials) and high specific strength (pisu unitateko indarra metalezko materialenaren baliokidea edo handiagoa da). Adibidez, beira-zuntzez indartutako poliamidaren indar espezifikoa (PA66+GF30) karbonozko altzairu arruntena baino handiagoa da, produktuen pisua eraginkortasunez murrizteko errendimendu mekanikoa bermatuz. Errendimendu hori bereziki garrantzitsua da automobilgintzan, aeroespaziala eta arina eta energia aurreztea bilatzen duten beste arlo batzuk, horrek erregai-kontsumoa eta karbono-isuriak murriztu ditzake.

Aldi berean, ingeniaritza-plastikoek higadura-erresistentzia eta marruskadura-erresistentzia nabarmenak dituzte, eta marruskadura-koefizientea txikia da, higadura erresistenteak diren piezen ekoizpenean erabil daitekeena (hala nola engranajeak, errodamenduak, bloke irristagarriak) lubrifikazio gehigarririk gabe edo lubrifikazio gutxiagorekin, produktuen mantentze-kostua murriztea. Adibidez, polioximetilenoa (POM) ingeniaritza plastikoek higadura erresistentzia bikaina dute eta izenez ezagutzen dira “plastikozko altzairua”, automobilgintzako engranajeen ekoizpenean oso erabilia dena, osagai elektrikoak eta higaduraren aurkako beste pieza batzuk.

1.3 Ingeniaritza Plastikoen Sailkapen Amankomuna

Ingeniaritza plastikoak mota ezberdinetan bana daitezke egitura kimikoaren arabera, errendimendu maila eta aplikazio eremua. Sailkapen metodo arruntak honako hauek dira, horrek ingeniaritza plastiko ezberdinen prozesatzeko ezaugarriak eta aplikazio eszenatokiak hobeto ulertzen laguntzen du, eta estrusio-ekipo eta prozesatzeko teknika egokiak hautatzea:

1.3.2 Egitura Kimikoaren araberako sailkapena

Kate molekularraren egitura kimikoaren arabera, ingeniaritza plastikoak poliamidatan bana daitezke (PA), polikarbonatoa (PCa), polioximetilenoa (POM), poliesterra (PET, PBT), polyphenylene sulfide (PPS), polieter eter zetona (PEEK), etab. Ingeniaritza plastiko mota bakoitzak bere errendimendu-ezaugarri eta prozesatzeko eskakizun bereziak ditu:

• Poliamida (PA): Nylon bezala ere ezaguna, erresistentzia mekaniko bikaina du, higadura erresistentzia, gogortasuna eta erresistentzia kimikoa, baina ur xurgapen handia du, horrek dimentsio-egonkortasunari eragiten dio. Barietate arruntak PA6 dira, PA66, PA11, PA12, etab. Oso erabilia da automobilgintzako piezetan (engranajeak, errodamenduak, hartune-kolektiboak), konektore elektrikoak, ehun-zuntzak, etab.
• Polikarbonatoa (PCa): Gardentasun bikaina du, inpaktu indarra, bero-erresistentzia eta isolamendu elektrikoa, baina higadura-erresistentzia eskasa du eta urratzen erraza da. Oso erabilia da eremu elektriko eta elektronikoan (kableatu taulak, lanpara-estalkiak), automobilgintza arloak (farolen lenteak, tresna-panelak), medikuntza arloak (ontziak medikoak), etab.
• Polioximetilenoa (POM): Higadura erresistentzia bikaina du, marruskadura erresistentzia, dimentsio-egonkortasuna eta erresistentzia mekanikoa, eta ez da erraza ura xurgatzen. bezala ezagutzen da “plastikozko altzairua” eta oso erabilia da automobilgintzako piezetan (engranajeak, bloke irristagarriak), osagai elektrikoak (etengailuak, errodamenduak), pieza mekanikoak, etab.

It is mainly used in high-end fields such as aerospace, inplante medikoak, and high-temperature resistant electrical components.

1.3.3 Classification by Application Field

According to the application field, engineering plastics can be divided into automotive-grade engineering plastics, electrical-grade engineering plastics, medical-grade engineering plastics, aerospace-grade engineering plastics, etab. Different application fields have different requirements on the performance of engineering plastics. Adibidez, automotive-grade engineering plastics require good heat resistance, impact strength and weather resistance; maila elektrikoko ingeniaritza plastikoek isolamendu elektriko ona eta suaren aurkako erresistentzia behar dute; Medikuntza-mailako ingeniaritza plastikoek biobateragarritasun eta antzutasun ona behar dute; aeroespazialeko ingeniaritza-plastikoek tenperatura altuko erresistentzia ona behar dute, pisu baxua eta indar handia.

2. Ingeniaritza Plastikoen Core Prozesatzeko Teknologia: Torloju Bikoitzeko Estrusio Teknologia

Ingeniaritza plastikoen prozesamenduak estrusioa hartzen du barne, injekzio-moldaketa, putz moldatzea, moldaketa eta beste metodo batzuk, horien artean, torloju bikoitzeko estrusio-teknologia ingeniaritza-konposatu plastikoak ekoizteko oinarrizko teknologia da (esaterako, aldatutako ingeniaritza-plastikoak, ingeniaritza-plastiko indartuak) eta erdilandutako produktuak (hodiak esaterako, orriak, zuntzak). Torloju bakarreko estrusio-teknologiarekin alderatuta, torloju bikoitzeko estrusio-teknologiak ebakidura-indar indartsuaren abantailak ditu, nahasketa efektu ona, tenperatura kontrol zehatza, egoitza-denbora laburra eta lehengaietara moldagarritasun handia, horrek ingeniaritza plastikoen prozesatzeko zailtasunak eraginkortasunez konpon ditzake (hala nola, gainberotzearen eta degradazio hidrolitikoarekiko sentikortasuna, nahasketa efektu eskasa, prozesatzeko eraginkortasun baxua) eta ingeniaritza plastikozko produktuen kalitatea bermatzea.

2.1 Ingeniaritza Plastikoen Zailtasunak Prozesatzeko eta Estrusio Ekipoen Baldintzak

Lehen esan bezala, ingeniaritza plastikoek errendimendu integral bikaina dute, baina haien prozesatzeko zailtasuna plastiko orokorrena baino handiagoa ere bada, batez ere egitura molekular bereziengatik eta errendimendu-ezaugarriengatik. Ingeniaritza plastikoen prozesatzeko zailtasun nagusiak eta estrusio-ekipoei dagozkien eskakizunak honako hauek dira:

2.1.1 Gainberotzearen eta degradazio hidrolitikoarekiko sentikortasuna

Ingeniaritza plastiko gehienak (hala nola, PA, PBT, PPS) are sensitive to overheating and hydrolytic degradation. If the processing temperature is too high or the residence time in the extruder is too long, the molecular chain of the engineering plastic will break, resulting in thermal decomposition, which will reduce the mechanical properties, heat resistance and other performance of the product, and even cause discoloration, carbonization and other defects. In addition, ingeniaritza plastiko batzuk (hala nola, PA) have high water absorption, and the moisture in the material will cause hydrolytic degradation during the high-temperature processing process, affecting the product quality.

This puts forward two key requirements for extrusion equipment: first, precise temperature control capacity, which can strictly control the processing temperature within the optimal range of engineering plastics, avoid local overheating, and the temperature control precision should reach ±1℃; second, short residence time, which can reduce the time that the material stays in the extruder barrel, avoid thermal decomposition and hydrolytic degradation. Twin-screw extruders have the advantages of short residence time (usually 1-5 minutuak) and precise temperature control, which are more suitable for engineering plastics processing than single-screw extruders (residence time 5-10 minutuak).

2.1.2 High Requirements on Mixing and Dispersing Effect

In engineering plastics processing, it is often necessary to add modifiers (such as glass fiber, karbono-zuntza, talc, suaren atzeragarriak, compatibilizers) to improve the performance of the product (such as reinforcing, toughening, flame retardant). Adibidez, adding glass fiber to PA can improve its strength and dimensional stability; adding flame retardants to PBT can improve its flame retardancy. The uniform mixing and dispersion of modifiers in the engineering plastic matrix is crucial to the performance of the final product. If the mixing and dispersing effect is poor, the modifiers will agglomerate, resulting in uneven performance of the product, and even reduce the mechanical properties of the product.

This requires the extrusion equipment to have strong shearing force and mixing capacity. Twin-screw extruders adopt intermeshing co-rotating or counter-rotating twin-screw structure, and the relative movement between the screws can generate strong shear force and kneading force, which can fully break the agglomerates of modifiers, make the modifiers uniformly dispersed in the engineering plastic matrix, and ensure the mixing and dispersing effect. In addition, the modular design of the twin-screw can freely combine different screw elements (such as conveying elements, mixing elements, shearing elements) according to the type of engineering plastic and modifier, further improving the mixing and dispersing effect.

2.1.3 High Requirements on Wear Resistance of Equipment

In the processing of reinforced engineering plastics (such as glass fiber reinforced PA, carbon fiber reinforced PPS), the added glass fiber, carbon fiber and other modifiers have high hardness, which will cause serious wear to the screw and barrel of the extruder during the extrusion process. If the screw and barrel have poor wear resistance, they will be worn quickly, resulting in reduced shearing force and mixing capacity of the extruder, affecting the product quality and reducing the service life of the equipment.

Honek estrusorearen torlojua eta kanoia kalitate handiko higadura erresistenteak diren materialekin egin behar dira eta fabrikazio teknologia aurreratuarekin prozesatu behar dira.. Gure HTS serieko estrusoreek inportatutako higadura-erresistentea den aleazio-altzairua hartzen dute torlojurako eta kanoirako, eta konposite bimetalikoen tratamendua edo laser bidezko estalduraren tratamendua jasaten dute, horrek asko hobetzen du torlojuaren eta kanoiaren higadura-erresistentzia eta korrosioarekiko erresistentzia, eta gogortasun handiko aldagailuak dituzten ingeniaritza-plastiko indartuen prozesatzera egokitu daiteke.

2.1.4 Prozesatzeko jariakortasuna eta presioa kontrolatzeko eskakizun handiak

Ingeniaritza plastiko batzuk (hala nola, PPS, PEEK) biskositate handia eta prozesatzeko jariakortasun eskasa dute, Estrusioak garraiatzeko ahalmen handia eta presioa kontrolatzeko ahalmena eskatzen duena estrusioaren aurrerapen leuna bermatzeko. Garraio-ahalmena nahikoa ez bada edo presio-kontrola ezegonkorra bada, estrusio-abiadura irregularra eragingo du, produktuaren tamaina ezegonkorra, eta baita ekipoak blokeatzea ere.

Torloju bikoitzeko estrusoreek garraiatzeko ahalmen handia eta presioa kontrolatzeko ahalmen egonkorra dute. Torloju bikien uztartzeak ponpaketa indar handia sor dezake, biskositate handiko ingeniaritza plastikozko materialak eraginkortasunez helarazi ditzakeena; aldi berean, extruder doitasun handiko presio sentsore batekin hornituta dago, Estrusio-presioa denbora errealean kontrolatu eta torloju-abiadura eta elikadura-abiadura automatikoki doi ditzake estrusio-presioaren egonkortasuna eta prozesatzeko aurrerapen leuna bermatzeko..

2.2 Ingeniaritza Plastikoen Lan-printzipioa eta Prozesuaren Fluxua Torloju Bikoitzeko Estrusioa

Ingeniaritza plastikoen torloju biko estrusio-prozesua prozesu fisiko eta kimiko konplexua da, eta horrek tenperatura bezalako faktore anitzen elkarrekintza dakar, presioa, ebakidura-indarra eta denbora. Helburu nagusia ingeniaritza plastikozko lehengaiak eta modifikatzaileak urtzea eta plastifikatzea da, nahastu uniformeki, eta gero estruitu behar den forman (hala nola, partikulak, hodiak, orriak, zuntzak) trokelaren buruaren bidez. Lan-printzipio espezifikoa eta prozesu-fluxua honako hauek dira:

2.2.1 Lehengaien aurretratamendua

Lehengaien aurretratamendua ingeniaritza plastikoen estrusioa prozesatzeko oinarria da, prozesatzeko efektuari eta produktuaren kalitateari zuzenean eragiten diona. Ingeniaritza plastikoen lehengaiek batez ere ingeniaritza plastikozko erretxina dira (hala nola, PA, PCa, POM), aldatzaileak (such as glass fiber, karbono-zuntza, talc, suaren atzeragarriak), compatibilizers, lubrifikatzaileak eta beste gehigarri batzuk. Aurretratamenduaren urratsak hauek dira:

• Lehortzeko tratamendua: Ingeniaritza plastiko gehienak (hala nola, PA, PBT, PPS) have high water absorption, and the moisture in the raw materials will cause hydrolytic degradation during high-temperature processing, resulting in product defects (such as bubbles, cracks, reduced mechanical properties). Horregatik, the raw materials must be dried before processing. The drying temperature and time are determined according to the type of engineering plastic: adibidez, PA6 is dried at 80-100℃ for 4-6 orduak, PA66 is dried at 100-120℃ for 6-8 orduak, PBT is dried at 120-140℃ for 2-4 orduak, PPS is dried at 150-160℃ for 3-5 orduak. The moisture content of the dried raw materials should be controlled below 0.1%-0.2%.
• Premixing Treatment: According to the formula ratio, the dried engineering plastic resin, modifiers and additives are put into a high-speed mixer for premixing. The purpose of premixing is to make the modifiers and additives uniformly adhere to the surface of the resin particles, improve the mixing effect during extrusion, and avoid local agglomeration of modifiers. The mixing speed is generally 800-1200 rpm, and the mixing time is 5-10 minutuak. For some modifiers with poor compatibility (such as glass fiber and PA), a compatibilizer should be added during premixing to improve the compatibility between the modifier and the resin.
• Crushing and Sieving: For engineering plastic resins with large particle size or modifiers with uneven particle size (such as glass fiber), crushing and sieving treatment should be carried out to ensure the uniformity of raw materials and avoid affecting the mixing and dispersing effect during extrusion. The particle size of the crushed raw materials should be controlled at 20-40 mesh.

2.2.2 Elikadura eta Garraioa

Aurrenahastutako lehengaiak torloju biko estrusorearen elikadura-huskara bidaltzen dira torloju-elikadura edo gerriko-elikadura baten bidez.. Estrusorearen elikadura-gailuak maiztasun-bihurketa abiadura erregulatzeko funtzio batekin hornituta egon ohi da, elikadura-abiadura torloju-abiaduraren eta estrusio-abiaduraren arabera doi dezake, materialak estrusio-barrunbean egonkor eta uniformeki sartzen direla ziurtatzeko., material metaketa edo nahikoa elikadura saihestuz. Elikadura-toloiak lehortzeko gailu batekin ere hornituta dago elikaduran zehar lehengaiek hezetasuna berriro xurga ez dezaten..

2.2.3 Urtzea, Nahasketa eta mozketa

Torloju biko estrusorearen estrusio-barrunbean sartzen diren materialak etengabe bultzatzen dituzte biraka egiten duten torlojuek. The extrusion cavity is composed of a screw and a barrel, eta estrusio-barrunbearen bolumena pixkanaka gutxitzen da ardatzaren norabidean. When the screws rotate, the materials are gradually compressed under the action of the screws and the barrel, and the pressure in the extrusion cavity gradually increases (generally 5-15MPa).

Aldi berean, the materials are subjected to strong shear force and friction force generated by the relative movement between the screws and the barrel, as well as between the screw flights. The shear force and friction force can fully break the agglomerates of modifiers, make the modifiers uniformly dispersed in the melted engineering plastic resin, and promote the fusion and compatibility between the modifier and the resin. The friction force can also generate a certain amount of heat, which is combined with the external heating of the barrel (berogailu elektrikoa edo lurrun berogailua) ingeniaritza plastikozko erretxina pixkanaka urtu eta plastifikatzeko.

Estrusorearen barrika normalean banatzen da 4-6 tenperatura kontrolatzeko atalak (elikadura atala, urtze-atala, nahasketa atala, homogeneizatzeko atala, die buru atala), eta atal bakoitzaren tenperatura zehatz-mehatz kontrolatzen da ingeniaritza plastiko motaren arabera. Adibidez, PA66+GF30 prozesatzen denean (beira-zuntzez indartua PA66), elikadura ataleko tenperatura 120-140 ℃ da, urtze-atala 250-260 ℃ da, nahasketa atala 260-270 ℃ da, homogeneizatzeko sekzioa 250-260 ℃ da, eta trokelaren buruaren sekzioa 240-250 ℃ da. Tenperaturaren kontrol zehatzak erretxina guztiz urtu dela bermatu dezake deskonposizio termikorik gabe, eta aldatzaileak uniformeki sakabanatuta daude.

2.2.4 Estrusioa eta Konformazioa

Guztiz urtua, nahastutako eta sakabanatutako materiala estrusorearen trokelaren burura bultzatzen da torlojuen bidez. Trokelaren burua azken produktuaren formaren arabera diseinatu da: ingeniaritza-konposatu plastikoak ekoizteko (granulak), trokelaren burua hainbat zulo zirkularrez hornituta dago (trokelen zuloen kopurua eta tamaina pikorren partikulen tamainaren arabera zehazten dira); hodiak ekoizteko, orriak, zuntzak, trokelaren burua dagokien formatan diseinatuta dago (hala nola, hodietarako trokel zirkularra, xafletarako trokel laua).

Materiala trokel-burutik abiadura handian ateratzen da produktu erdi landu jarraituak osatzeko (hala nola, pikorentzako zerrendak, hodiak, orriak). Trokelaren buruaren tenperatura homogeneizatzeko atalarena baino zertxobait baxuagoa da, which can prevent the material from decomposing due to excessive temperature and ensure the shaping effect of the semi-finished products. The extrusion speed is controlled according to the type of engineering plastic and the shape of the product, generally ranging from 0.5-5m/min.

2.2.5 Cooling and Solidification

The extruded semi-finished products are sent to a cooling device for rapid cooling and solidification. The cooling method is determined according to the shape of the product: for strips (granule production), water tank cooling is usually used, and the cooling water temperature is controlled at 20-30℃, and the cooling time is 2-5 minutuak; for pipes and sheets, air cooling or water spray cooling is used, and the cooling speed should be controlled to avoid product deformation due to uneven cooling. Rapid cooling can make the semi-finished products solidify quickly, maintain the shape and size of the products, and improve the mechanical properties of the products.

2.2.6 Cutting and Post-Processing

After cooling and solidification, the semi-finished products are processed into the final product through cutting or other post-processing steps. For the production of engineering plastic compounds (granulak), the cooled strips are sent to a granulator for cutting, and the granulator is equipped with a rotary knife, which can cut the strips into granular products with uniform size (the particle size is generally 2-5mm, which can be adjusted according to customer needs). For the production of pipes and sheets, the cooled semi-finished products are cut into the required length through a cutting machine; for the production of fibers, the cooled filaments are drawn and wound to form fiber products.

In addition, the final product also needs to undergo post-processing steps such as screening, inspection and packaging. The screening step is to remove unqualified products (such as too large, too small or agglomerated particles); the inspection step is to detect the performance (such as mechanical strength, beroarekiko erresistentzia, dimentsioko zehaztasuna) of the product to ensure that it meets the customer’s requirements; the packaging step is to package the qualified product in a sealed and moisture-proof manner to prevent the product from absorbing moisture and affecting the quality.

2.3 Key Factors Affecting Engineering Plastics Twin-Screw Extrusion Effect

The effect of twin-screw extrusion directly affects the quality and performance of engineering plastic products. There are many factors affecting the extrusion effect, mainly including raw material characteristics, formula ratio, premixing effect, extrusion parameters and die head structure. Mastering these key factors and making scientific adjustments can ensure the stability of the extrusion effect and the consistency of product quality.

2.3.1 Raw Material Characteristics

The type, particle size, moisture content and purity of raw materials have a great impact on the extrusion effect. Adibidez, the particle size of engineering plastic resin and modifiers should be uniform; if the particle size is uneven, it will lead to uneven melting and mixing of materials. The moisture content of raw materials must be strictly controlled below 0.1%-0.2%; if the moisture content is too high, it will cause hydrolytic degradation of the material and bubbles in the product. Lehengaien garbitasuna ere oso garrantzitsua da; ezpurutasunak lehengaietan (metalak esaterako, harriak, hautsa) ez du produktuaren kalitatean bakarrik eragingo, baina baita estrusorearen torlojua eta kanoia ere higadura, eta baita ekipoak blokeatzea ere.

2.3.2 Formula ratioa

Ingeniaritza-konposatu plastikoen formula-erlazioa (erretxina proportzioa, modifikatzaileak eta gehigarriak) produktuaren errendimendua zehazteko gakoa da. Aldatzaileen mota eta dosia produktuaren errendimendu-baldintzen arabera zehaztu behar dira. Adibidez, gehituz 20%-40% beira-zuntzak PA-ra nabarmen hobetu dezake bere indarra eta dimentsio-egonkortasuna, baina gehiegizko beira-zuntzak produktuaren gogortasuna eta prozesatzeko jariakortasuna murriztuko ditu. Gehigarrien mota eta dosia ere arrazoiz parekatu behar dira: compatibilizers modifikatzaileen eta erretxinaren arteko bateragarritasuna hobetu dezakete, and the dosage is generally 0.5%-2%; lubricants can reduce the friction between materials and equipment, improve processing fluidity, and the dosage is generally 0.3%-1%; antioxidants can prevent the material from thermal oxidation degradation during processing, and the dosage is generally 0.1%-0.5%.

2.3.3 Premixing Effect

Premixing is the foundation of extrusion processing. The uniformity of premixing directly affects the mixing and dispersing effect of modifiers during extrusion. If the premixing is uneven, the modifiers cannot be uniformly adhered to the surface of the resin, resulting in local agglomeration of modifiers, uneven mixing of materials during extrusion, and reduced product performance. To ensure the premixing effect, it is necessary to control the mixing speed, mixing time and mixing temperature: the mixing speed is 800-1200 rpm, the mixing time is 5-10 minutuak, and the mixing temperature is controlled at 40-60℃ (tenperatura egokiak gehigarrien atxikimendua hobe dezake eta nahasketa uniformea ​​susta dezake).

2.3.4 Estrusio-parametroak

Estrusio-parametroak dira estrusio-efektuari eragiten dioten faktore garrantzitsuenak, batez ere torlojuaren abiadura barne, estrusio-tenperatura eta estrusio-presioa.

• Torloju Abiadura: Ingeniaritza plastikoetarako torloju biko estrusoreen torlojuaren abiadura, oro har, bitartekoa da 100 to 1000 rpm. Gure HTS serieko estrusoreek gehienezko abiadura lor dezakete 1000 rpm. Zenbat eta handiagoa izan torlojuaren abiadura, zenbat eta handiagoa izan materialek jasotzen duten ebakidura-indarra eta marruskadura-indarra, orduan eta hobea izango da modifikatzaileen nahasketa eta sakabanaketa efektua, eta ekoizpen-eraginkortasun handiagoa. Hala ere, torlojuaren abiadura handiegia bada, estrusio-barrunbean materialen egonaldi-denbora laburregia da, ondorioz, erretxina osorik ez urtzea, materialak nahikoa nahastea, eta produktuaren kalitate irregularra; torlojuaren abiadura baxuegia bada, ebakidura-indarra eta marruskadura-indarra nahikoak dira, aldatzaileak ezin dira guztiz sakabanatu, eta ekoizpen-eraginkortasuna baxua da. Torlojuaren abiadura ingeniaritza plastiko motaren eta modifikatzaile motaren arabera egokitu behar da: biskositate handiko ingeniaritza plastikoetarako (hala nola, PPS, PEEK), torlojuaren abiadura txikiagoa behar da urtze eta nahasketa nahikoa bermatzeko; ingeniaritza-plastiko indartuetarako (such as glass fiber reinforced PA), torlojuaren abiadura handiagoa behar da beira-zuntzaren sakabanaketa uniformea ​​bermatzeko.
• Estrusio-tenperatura: Estrusio-tenperatura gakoa da ingeniaritza plastikoen urtze eta plastifikazioa bermatzeko. Kupelaren eta trokelaren atal bakoitzaren tenperatura zehaztasunez kontrolatu behar da ingeniaritza plastiko motaren arabera.. Elikadura ataleko tenperatura baxuagoa da (lehengaien lehortzeko tenperatura baino apur bat handiagoa), hau da, batez ere, materialak opilatzea saihesteko eta elikadura leuna bermatzeko; urtze-atalaren tenperatura ertaina da, hau da, batez ere, erretxina urtzea eta plastifikatzea sustatzeko; nahaste-atalaren tenperatura altuagoa da, hau da, batez ere, zizaila eta nahasketa efektua hobetzeko, eta modifikatzaileen sakabanaketa uniformea ​​sustatzea; homogeneizatzeko atalaren tenperatura nahastearen atalarena baino zertxobait baxuagoa da, hau da, batez ere, materialen tenperatura eta biskositate uniformea ​​bermatzea, eta deskonposizio termikoa saihestu; trokel-buruaren atalaren tenperatura homogeneizatzeko atalarena baino zertxobait baxuagoa da, which is to ensure the shaping effect of the semi-finished products. The temperature control precision should reach ±1℃ to avoid local overheating and thermal decomposition of the material.
• Estrusio-presioa: The extrusion pressure of engineering plastics twin-screw extrusion generally ranges from 5 to 15MPa. The pressure in the extrusion cavity is mainly determined by the compression ratio of the screw, the die hole size and the screw speed. The higher the extrusion pressure, the better the mixing and dispersing effect of materials, and the denser the product. Hala ere, if the pressure is too high, it will increase the energy consumption and wear of the equipment, and even cause the die head to block; if the pressure is too low, the materials cannot be fully compressed and mixed, the product is loose, and the performance is unstable. The extrusion pressure should be adjusted according to the type of engineering plastic and the shape of the product: for high-viscosity materials and products with small die holes, a higher extrusion pressure is needed.

2.3.5 Die Head Structure

The die head structure mainly includes the shape, size and number of die holes, which directly affects the shaping effect and quality of the product. For the production of engineering plastic compounds (granulak), the die head should be equipped with multiple uniform die holes, and the size of the die holes should be matched with the particle size of the product; for the production of pipes and sheets, the die head should be designed according to the shape and size of the product, and the flow channel of the die head should be smooth to avoid material accumulation and local overheating. The die head should also be equipped with a temperature control device to ensure the uniform temperature of the die head and the stable shaping of the product.

3. Our HTS Series Extruders: Professional Solutions for Engineering Plastics Processing

Aspaldi gabiltza ikerketan, development and production of high-performance twin-screw extruders, and have accumulated rich experience in the field of engineering plastics processing. According to the processing characteristics of engineering plastics (sensitivity to overheating and hydrolytic degradation, high requirements on mixing and dispersing effect, high viscosity) and application needs, we have developed the HTS series twin-screw extruders specially for engineering plastics processing. Our HTS series extruders adopt high-torque gearboxes, 14 Nm/cm³-ko momentu espezifikoarekin eta gehienez 1000 rpm-ko abiadurarekin, irteera handiagoa lor dezakeena, bizileku denbora laburragoa, sakabanagarritasun hobea eta tenperatura kontrol zehatzagoa, ingeniaritza plastiko ezberdinen prozesatzeko beharretara ezin hobeto egokitzen da.

3.1 Ingeniaritza Plastikoen Prozesamendurako HTS Serieko Extruders-en oinarrizko abantailak

3.1.1 Torque eta Abiadura Handia, Produkzio-eraginkortasun handia

Ingeniaritza plastikoek biskositate handia eta prozesatzeko jariakortasun eskasa dute, estrusoreak momentu eta garraiatzeko ahalmen handia izatea eskatzen dutenak. Gure HTS serieko estrusoreek era independentean garatutako eta fabrikatutako pare handiko engranaje-kutxak hartzen dituzte (HTS PLUS seriea eta HTS SUPER seriea) edo Europako fabrikatzaile nagusietatik inportatuak (HTS BASIC seriea), 14 Nm/cm³-ko momentu espezifikoarekin, hau da, torloju biko estrusore arruntena baino askoz handiagoa (Pare orokorra 8-12 Nm/cm³ da). Momentu handiko diseinuak estrusoreak biskositate handiko ingeniaritza plastikozko materialak modu egonkorrean helarazi ditzakeela bermatzen du, saihestu material metaketa eta ekipoak blokeatzea, eta estrusio-prozesuaren egonkortasuna hobetzea.

Aldi berean, HTS serieko estrusoreek abiadura handiko diseinua dute, gehienez 1000 rpm-ko abiadurarekin. Abiadura handiak ebakidura-indar eta nahasketa-indar handia sor ditzake, which can fully break the agglomerates of modifiers, modifikatzaileak erretxina-matrizean uniformeki sakabanatu, eta nahasketa eta sakabanaketa efektua hobetu. In addition, abiadura handiko diseinuak ekoizpenaren eraginkortasuna ere asko hobetzen du: estrusore arruntekin alderatuta, HTS serieko estrusoreen ekoizpen-eraginkortasuna handitu daiteke 30%-50%, ingeniaritza plastikoen enpresen eskala handiko ekoizpen beharrak ase ditzakeena.

3.1.2 Egoitza-denbora laburra, Degradazio termikoa eraginkortasunez saihestea

As engineering plastics are sensitive to overheating and hydrolytic degradation, the residence time of materials in the extruder is crucial. Our HTS series extruders adopt an optimized screw structure and barrel design, with a short residence time of only 1-3 minutuak, which is much shorter than that of ordinary twin-screw extruders (5-10 minutuak) and single-screw extruders (10-15 minutuak). The short residence time can effectively reduce the contact time between the material and high temperature, avoid thermal decomposition and hydrolytic degradation of the material, and ensure the mechanical properties and heat resistance of the product.

In addition, the screw of the HTS series extruders adopts a modular design, and different screw elements can be freely combined according to the type of engineering plastic, horrek materialaren egoitza-denbora gehiago doi dezake, ingeniaritza-plastiko mota ezberdinek prozesatzeko garaian egonaldi-denbora optimoa lor dezaketela ziurtatzea.

3.1.3 Tenperaturaren Kontrol zehatza, Errendimendu egonkorra

HTS serieko estrusoreek tenperatura kontrolatzeko sistema adimendun aurreratua hartzen dute, upelaren eta trokelaren atal bakoitzaren tenperaturaren kontrol zehatza egin dezakeena. Tenperatura kontrolatzeko zehaztasuna ±1 ℃ irits daiteke, which can strictly control the processing temperature within the optimal range of engineering plastics, saihestu tokiko gainberotzea eta materialaren deskonposizio termikoa. Tenperatura kontrolatzeko sistema denbora errealeko monitorizazio eta alarma funtzio batekin hornituta dago: edozein ataletako tenperaturak ezarritako tartea gainditzen badu, sistemak alarma-abisua emango du garaiz, eta baita berokuntza potentzia automatikoki egokitu edo ekipoa itzali behar izanez gero, ekipoen hutsegite eta produktuen kalitate arazoak ekiditeko.

In addition, the barrel of the HTS series extruders adopts a double-layer jacket design, which can realize rapid heating and cooling, and improve the response speed of temperature control. The die head is also equipped with an independent temperature control device, which ensures the uniform temperature of the die head and the stable shaping of the product.

3.1.4 Excellent Mixing and Dispersing Effect

The HTS series extruders adopt an intermeshing co-rotating twin-screw structure, with a reasonable screw pitch, lead and compression ratio design. The intermeshing and rotating of the twin screws can generate strong shear force and kneading force, which can fully break the agglomerates of modifiers (such as glass fiber, karbono-zuntza, talc), make the modifiers uniformly dispersed in the engineering plastic resin matrix, and ensure the mixing and dispersing effect. The mixing uniformity of the HTS series extruders can reach more than 95%, hau da, torloju biko estrusore arruntena baino askoz handiagoa (85%-90%).

HTS serieko estrusoreen torlojuak diseinu modularra hartzen du, eta torloju-elementu mota desberdinak (such as conveying elements, mixing elements, shearing elements) aske konbinatu daiteke ingeniaritza plastiko eta modifikatzaile motaren arabera. Adibidez, beira-zuntzez indartutako ingeniaritza plastikoak prozesatzen direnean, zizaila-elementu gehiago konfigura daitezke zizaila-efektua hobetzeko eta beira-zuntzaren sakabanaketa uniformea ​​bermatzeko; biskositate handiko ingeniaritza plastikoak prozesatzen direnean (hala nola, PPS), nahasketa-elementu gehiago konfigura daitezke nahaste-efektua hobetzeko eta materialaren biskositate uniformea ​​bermatzeko.

3.1.5 Higadura Erresistentzia handia, Zerbitzu-bizitza luzea

In the processing of reinforced engineering plastics (such as glass fiber reinforced PA, carbon fiber reinforced PPS), gehitutako modifikatzaileek gogortasun handia dute, horrek higadura larria eragingo dio estrusorearen torlojuari eta kanoiari. Gure HTS serieko estrusoreek kalitate handiko higadura-erresistentzia materialak eta fabrikazio-teknologia aurreratua hartzen dituzte oinarrizko osagaien higadura-erresistentzia bermatzeko..

HTS serieko estrusoreen torlojua eta kanoia higadura erresistentea den aleazio altzairuz eginda daude (hala nola, 38CrMoAlA), eta konposite bimetalikoen tratamendua edo laser bidezko estalduraren tratamendua jasaten dute. Torlojuaren eta kanoiaren gainazaleko gogortasuna ≥65 HRC irits daiteke (HTS BASIC seriea) eta ≥70 HRC (HTS PLUS seriea eta HTS SUPER seriea), higadura-erresistentzia eta korrosioarekiko erresistentzia oso handia duena, eta gogortasun handiko aldagailuek eragindako higadurari eraginkortasunez aurre egin diezaioke. Horrek asko luzatzen du torlojuaren eta kanoiaren zerbitzu-bizitza: HTS serieko estrusoreen torlojuaren eta kanoiaren zerbitzu-bizitza da 2-3 estrusore arruntena aldiz, osagaiak ordezkatzeko maiztasuna eta ekipoen mantentze-kostua murriztea.

In addition, we also provide professional wear detection services for the screw and barrel. Our technical team will regularly detect the wear degree of the screw and barrel for customers, issue a detailed wear report, and put forward targeted replacement and maintenance suggestions, ensuring that customers only replace components when necessary, avoiding unnecessary waste.

The HTS series extruders have a wide application range, which can adapt to the processing needs of various engineering plastics, including general engineering plastics (PA, PCa, POM, PET, PBT) and special engineering plastics (PPS, PEEK, PSU, PES). The extruders can also adapt to the processing of various modified engineering plastics, such as reinforced engineering plastics (glass fiber reinforced, carbon fiber reinforced), toughened engineering plastics, flame-retardant engineering plastics, antistatic engineering plastics, etab.

The modular design of the HTS series extruders (torlojua, barrika, burua hil, etab.) makes the replacement of components more convenient and quick. When customers need to adjust the product type (such as switching from PA processing to PPS processing) or modify the formula, they only need to replace the corresponding components, without replacing the entire equipment, which reduces the cost of equipment transformation and improves the flexibility and adaptability of the equipment. In addition, the HTS series extruders can also be matched with different auxiliary equipment (such as high-speed mixers, dryers, coolers, granulators, screening machines, packaging machines) to form a complete automatic production line, realizing continuous production from raw material pretreatment to product packaging.

3.1.7 Intelligent Control, Easy Operation and Maintenance

The HTS series extruders adopt a PLC intelligent control system and a touch screen operation interface, sinplea eta intuitiboa dena, funtzionatzeko erraza. The system can store multiple sets of product formulas and processing parameters. When customers produce different types of engineering plastics, dagozkien formula eta parametroei bakarrik deitu behar diete, behin eta berriz arazketarik egin gabe, which saves time and improves production efficiency.

The system is also equipped with a real-time monitoring function, which can monitor the key parameters of the extrusion process (such as temperature, presioa, torlojuaren abiadura, feeding speed) in real time, and record the production data (such as output, processing time) for later query and analysis. For the HTS SUPER series extruders, we also provide a cloud control function, which can realize remote parameter adjustment, production data monitoring and predictive maintenance of equipment, realizing intelligent production management.

In addition, HTS serieko estrusoreek egiturazko diseinu zentzuzkoa hartzen dute, horrek mantentze-lanak erosoago egiten ditu. Torlojua, barrika, trokelaren burua eta beste osagai batzuk azkar desmuntatu eta muntatu daitezke, horrek mantentze-denbora eta lan-intentsitatea murrizten ditu. Gure salmenta osteko zerbitzu taldeak instalazio profesionala eskainiko du, Bezeroentzako abian jartzeko eta trebatzeko zerbitzuak, bezeroek ekipamendua ondo erabil dezaketela ziurtatzea.

Hauek dira hautaketa-iradokizun zehatz batzuk:

3.3.1 Zehaztu Extruder Series Ingeniaritza Plastiko Motaren arabera

Ingeniaritza plastiko mota ezberdinek prozesatzeko eskakizun desberdinak dituzte, extruder serieen aukeraketa zehazten dutenak. Ingeniaritza orokorreko plastikoetarako (PA6, PA66, POM, PET, PBT) aldaketa-maila baxuarekin (betetze-kopurua ≤% 30), HTS BASIC seriea nahikoa da prozesatzeko beharrak asetzeko. Bere momentu ertainak eta konfigurazio malguak prozesatzeko efektua eta kostua orekatu ditzakete, which is very suitable for small and medium-sized enterprises that just start to engage in engineering plastics processing or focus on general-purpose products. For high-modified engineering plastics (filling amount 30%-50%, such as glass fiber reinforced PA, carbon fiber reinforced PBT) and special engineering plastics with moderate processing difficulty (hala nola, PPS), the HTS PLUS series is the preferred choice. Its high torque of 14Nm/cm³ and excellent mixing and dispersing capacity can effectively solve the problem of uneven dispersion of high-content modifiers, and its wear-resistant screw and barrel can adapt to the wear of hard modifiers, ensuring stable production. For high-end special engineering plastics (PEEK, PI, PSU, PES) and high-performance modified engineering plastics (filling amount ≥50%, such as carbon fiber reinforced PEEK), the HTS SUPER series must be selected. Its ultra-high torque, gehienezko 1000rpm-ko abiadura eta guztiz optimizatutako gako-egiturak biskositate handiari aurre egin diezaioke, tenperatura altuko erresistentzia eta goi mailako materialen prozesatzeko baldintza zorrotzak, deskonposizio termikoa eta materialaren degradazioa saihestea, eta azken produktuaren errendimendu handia bermatzea.

3.3.2 Zehaztu torlojuaren diametroa eta ekoizpen-ahalmena Prozesatzeko eskalaren arabera

Torloju biko estrusorearen torlojuaren diametroak zuzenean zehazten du produkzio-ahalmena, eta enpresek torlojuaren diametro egokia hautatu behar dute beren ekoizpen eskalaren eta eskaeraren arabera. Eskala txikiko ekoizpenerako (100kg/h – 500kg/h), hala nola, lote txikien pertsonalizazioa, produktuen ikerketa eta garapena edo eskaera txikiak, HTS BASIC seriea 30 mm-ko torlojuaren diametroa duena – 65mm egokia da; eskala ertaineko ekoizpenerako (500kg/h – 2000kg/h), such as mass production of general modified engineering plastics, the HTS PLUS series with screw diameter of 65mm – 110mm can meet the demand; for large-scale production (1000kg/h – 3000kg/h), such as large-scale production of high-end special engineering plastics or large orders from downstream enterprises, the HTS SUPER series with screw diameter of 80mm – 130mm is the best choice. It should be noted that when selecting, enterprises should not blindly pursue large production capacity. They should also consider the fluctuation of order quantity. If the order quantity is unstable, they can choose equipment with adjustable speed and flexible production capacity (such as HTS BASIC series with frequency conversion speed regulation function) to avoid waste of equipment resources and energy.

3.3.3 Consider the Modification Demand and Mixing Effect

If the enterprise’s main products are modified engineering plastics, the mixing and dispersing effect of the extruder is the key factor to be considered. For products that need to add a variety of modifiers (such as flame retardants, compatibilizers, reinforcing agents) aldi berean, it is necessary to select extruders with excellent mixing performance, such as HTS PLUS series and HTS SUPER series with modular mixing screw elements. These two series can freely combine conveying elements, mixing elements and shearing elements according to the type of modifier, adjust the mixing intensity and residence time, and ensure that various modifiers are uniformly dispersed in the resin matrix. Adibidez, when processing flame-retardant modified PBT, more mixing elements can be configured to ensure the uniform dispersion of flame retardants, avoid local flame retardancy insufficiency; when processing glass fiber reinforced PA, more shearing elements can be configured to break the agglomeration of glass fiber and improve the bonding force between glass fiber and resin. In addition, if the enterprise has the demand of multi-variety and small-batch modification, it is recommended to select the extruder with quick replacement of screw elements (such as the modular screw design of HTS series), which can reduce the time of equipment adjustment and improve production efficiency.

3.3.4 Consider the Cost Budget and Comprehensive Benefits

Cost budget is an important factor for enterprises to select equipment, but it is not advisable to pursue low cost blindly. It is necessary to balance the initial purchase cost, later maintenance cost, energy consumption and production efficiency to maximize the comprehensive benefits. The HTS BASIC series has the lowest initial purchase cost, low energy consumption and simple maintenance, which is suitable for enterprises with limited budget and small production scale; the HTS PLUS series has a moderate initial purchase cost, but its high production efficiency, long service life and stable processing effect can reduce the later maintenance cost and improve product qualification rate, which is suitable for medium and large-sized enterprises with certain budget and pursuit of high performance; the HTS SUPER series has the highest initial purchase cost, but it can process high-end products with high added value, and its intelligent control and long service life can reduce labor cost and maintenance cost in the later period, which is suitable for large-scale enterprises with sufficient budget and focus on high-end market. In addition, enterprises should also consider the after-sales service of the equipment. Our HTS series extruders provide a complete after-sales service system, instalazioa barne, martxan jartzea, prestakuntza teknikoa, regular maintenance and quick replacement of spare parts, which can reduce the later operation risk of enterprises.

3.3.5 Consider the Compatibility with Auxiliary Equipment

Twin-screw extrusion processing of engineering plastics needs to be matched with a series of auxiliary equipment, such as raw material drying equipment, high-speed mixer, cooler, granulator, screening machine, packaging machine, etab. When selecting the extruder, enpresek estrusorearen eta ekipo osagarrien arteko bateragarritasuna kontuan hartu behar dute ekoizpen-lerro osoaren funtzionamendu ona bermatzeko. Gure HTS serieko estrusoreak ezin hobeto konbina daitezke hainbat ekipamendu osagarri estandarrekin, eta enpresaren lehendik dagoen ekipo osagarrien arabera ere pertsonaliza daiteke ekipamendu berrien eta ekipo osagarri zaharren arteko bateraezintasunak eragindako hondakinak saihesteko.. Adibidez, enpresak dagoeneko abiadura handiko nahasgailu bat badu, 500 kg-ko nahaste-gaitasuna duena, 500kg/h-ko ekoizpen-ahalmena duen HTS PLUS serieko estrusorea hauta dezake – 800kg/h parekatzeko, lehengaien aurrenahastearen eta estrusioaren ekoizpenaren koordinazioa bermatzea.
