1. Overview of Engineering Plastics Industry and Core Performance Characteristics

1.1 Current Situation and Development Trend of Engineering Plastics Industry

Engineering plastics refer to a class of plastic materials that can be used as structural materials and bear mechanical loads in a wide temperature range. Compared with general plastics (such as polyethylene PE, polypropylene PP, polyvinyl chloride PVC), engineering plastics have more excellent comprehensive performance, and can meet the harsh use requirements in industrial production and high-end product manufacturing. In recent years, driven by the upgrading of downstream industries such as automotive lightweight, 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 bilyan oo doolarka Mareykanka ah, and it is expected to maintain a compound annual growth rate of 7%-10% in the next five years. Waxaa ka mid ah, Asia-Pacific is the world’s largest engineering plastics production and consumption market, xisaabinta in ka badan 55% ee saamiga suuqa caalamiga ah, mainly due to the rapid development of automotive, electrical and electronic industries in China, Hindiya iyo dalal kale, as well as the continuous improvement of industrial supporting capacity and technological innovation level. Shiinaha, 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, and medical devices, 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: marka hore, waxqabadka sare iyo shaqeynta. 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 (such as flame retardancy, antistatic, antibacterial, radiation resistance), to adapt to the harsh working environment of high temperature, high pressure, corrosion and radiation; labaad, lightweight and integration. In the automotive, aerospace iyo beeraha kale, si loo gaaro yoolalka badbaadinta tamarta iyo dhimista qiiqa, balaastikada injineernimada ayaa si sii kordheysa loo isticmaalaa si loogu beddelo qalabka birta, iyo isku-dhafka naqshadeynta alaabta ayaa noqonaysa mid sare iyo mid sare, kuwaas oo yarayn kara tirada qaybaha, fududeeyaan habka wax soo saarka iyo dhimista kharashka; saddexaad, ilaalinta deegaanka iyo dib u warshadaynta. Iyadoo la xoojinayo siyaasadaha ilaalinta deegaanka ee caalamiga ah iyo wanaajinta wacyiga ilaalinta deegaanka, horumarinta iyo codsiga balaastikada injineernimada dib loo warshadayn karo, balaastikada injineernimada noolaha iyo tignoolajiyada habaynta deegaanka u saaxiib ayaa noqday diiradda warshadaha, yaraynta wasakhowga deegaanka ee ay sababaan qashinka balaastikada ah; afraad, sirdoonka iyo saxda ah ee qalabka processing. Balaastigga injineernimada ayaa leh dhib habayn heersare ah iyo shuruudaha tayada adag, kuwaas oo soo bandhigay shuruudo sare oo ku saabsan qalabka farsamaynta. Indheer garad, saxan sax ah oo hufan oo mataano-screw extruders ah iyo khadadka wax soo saarka ee tooska ah ayaa noqday kuwa ugu muhiimsan ee warshadaha, garashada la socodka wakhtiga dhabta ah, hagaajinta cabbirka tooska ah iyo dayactirka saadaalinta ee habka habsocodka; shanaad, kala duwanaanshaha goobaha codsiga. Balaastigga injineernimada ayaa si tartiib tartiib ah uga sii fidaya baabuurta dhaqameed, beeraha korontada iyo elektarooniga si tamar cusub, caafimaad, hawada sare, dhismaha iyo beeraha kale ee soo baxaya, furitaanka suuqa cusub.

Ka soo horjeeda asalkan, farsamada extrusion mataanaha, sida farsamada farsamaynta xudunta u ah xeryahooda caagga ah ee injineernimada, waxay noqotay furaha lagu wanaajinayo tartanka shirkadaha balaastikada injineerinka. Engineering plastics are sensitive to overheating and hydrolytic degradation, and have high requirements on processing temperature, shear force, residence time and temperature control precision. Our HTS series extruders are specially designed for the processing characteristics of engineering plastics, with high torque, high speed, precise temperature control and excellent dispersibility, which can effectively solve the processing difficulties of engineering plastics and help enterprises achieve high-quality, efficient and stable production.

1.2 Core Performance Characteristics of Engineering Plastics

Compared with general plastics and metal materials, engineering plastics have unique comprehensive performance, which determines their wide application in various industrial fields. Tilmaamaha waxqabadka asaasiga ah ee balaastikada injineernimada ayaa inta badan ka muuqda shanta dhinac ee soo socota, kuwaas oo sidoo kale soo bandhigay shuruudo gaar ah oo ku saabsan farsamaynta farsamada iyo qalabka:

1.2.1 Iska caabbinta kulaylka oo heersare ah iyo iska caabin qabow

Balaastigga injineernimada ayaa leh heerkul laqabsasho ballaaran, kuwaas oo ilaalin kara sifooyin farsamo oo wanaagsan (xoog, adkaanshaha, qallafsanaan) deegaan heerkul sare iyo mid hooseeya labadaba. Compared with general plastics, kuwaas oo inta badan luminaya hantidooda makaanikada 80-120 ℃, Inta badan balaastigga injineernimada waxay u shaqeyn karaan si deggan 100-250 ℃, iyo qaar ka mid ah caagagga injineernimada gaarka ah (sida PEEK, PI) xitaa waxay ku shaqayn kartaa heerkul ka sarreeya 300 ℃. Isla markaana, balaastikada injineernimada sidoo kale waxay leeyihiin iska caabin qabow oo wanaagsan, kaas oo ilaalin kara adkaanta wanaagsan heerkulka hooseeya (ka hooseeya -40 ℃), oo ma fududa jabka jabka. Waxqabadkani wuxuu ka dhigayaa balaastikada injineernimada oo ku habboon in lagu isticmaalo jawi heerkul daran, sida qaybaha matoorada baabuurta (heerkulka sare) iyo qalab koronto oo dibadda ah (heerkulka hooseeya).

Iska caabbinta kulaylka aadka u fiican ee balaastikada injineernimada ayaa inta badan sabab u ah qaab dhismeedka molecular ee gaarka ah (sida faraanti udgoon, giraanta heterocyclic) iyo xoogag xoog leh oo intermolecular ah, taas oo ka dhigaysa in aanay fududayn in ay dhalaaliyaan oo ay burburaan heerkulka sare. Si kastaba ha ahaatee, Tani waxay sidoo kale keenaysaa dhibaatooyin gaar ah si loo habeeyo: Heerkulka habaynta sare ayaa loo baahan yahay si looga dhigo inay dhalaaliyaan oo balaastigaan, iyo xakamaynta heerkulka saxda ah ayaa loo baahan yahay si looga fogaado burburka kulaylka.

1.2.2 Iska caabin Daxalka Wanaagsan iyo Waarta

Balaastigga injineernimada ayaa leh xasillooni kiimikaad oo heer sare ah iyo iska caabin daxalka, mana fududa in aysiidhku daxaleeyaan, alkalis, cusbo, 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. Tusaale ahaan, polyamide (PA) engineering plastics are resistant to most organic solvents and weak acids and alkalis; polycarbonate (PC) 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, outdoor electrical equipment, automotive exterior parts and other fields.

1.2.3 Easy Processing and High Production Efficiency

Compared with metal materials, engineering plastics have the advantages of easy processing, simple production process and high production efficiency. Metal materials usually need complex processing procedures such as forging, casting, makiinado, which have high energy consumption, low efficiency and high cost; while engineering plastics can be processed by extrusion, injection molding, blow molding and other methods, which can realize mass production, simplify the production process, reduce energy consumption and production cost. Tusaale ahaan, the processing cycle of an engineering plastic automotive part by injection molding is only a few seconds to tens of seconds, halka wareegga farsamaynta ee isla qaybta birta ay qaadan karto dhowr saacadood ilaa dhawr maalmood.

Si kastaba ha ahaatee, balaastigga injineernimada sidoo kale waxay leeyihiin dhibaatooyin habaysan: waxay u nugul yihiin kulaylka iyo xaalufka hydrolytic, Way fududahay in la dumiyo haddii heerkulka habayntu aad u sarreeyo ama wakhtiga deggenaanshaha aad u dheer yahay; isla markaasna, balaastikada injineernimada qaarkood (sida PA) leeyihiin nuugista biyaha sare, kaas oo saameeya saamaynta processing iyo tayada alaabta. Sidaa darteed, waxaa lagama maarmaan ah in la isticmaalo qalabka farsamaynta xirfadlayaasha ah iyo farsamooyinka farsamaynta sayniska si loo hubiyo tayada processing.

1.2.4 Xasilooni cabbir heer sare ah iyo dahaar koronto

Balaastikada injineernimada waxay leeyihiin xasillooni cabbir wanaagsan, iyo heerka dhimashadu waa mid yar (sida caadiga ah 0.3%-1.5%) inta lagu guda jiro habaynta iyo isticmaalka, 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, qalabka caafimaadka, iwm. The good dimensional stability of engineering plastics is mainly due to their high crystallinity, low water absorption (except for some varieties such as PA) iyo xoogag xoog leh oo intermolecular ah.

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 (strength per unit weight is equivalent to or even higher than that of metal materials). Tusaale ahaan, the specific strength of glass fiber reinforced polyamide (PA66+GF30) is higher than that of ordinary carbon steel, which can effectively reduce the weight of products while ensuring the mechanical performance. This performance is particularly important in the automotive, aerospace and other fields that pursue lightweight and energy saving, which can reduce fuel consumption and carbon emissions.

Isla markaana, engineering plastics also have outstanding wear resistance and friction resistance, and the friction coefficient is small, which can be used in the production of wear-resistant parts (such as gears, dhalista, sliding blocks) iyada oo aan lahayn saliid dheeraad ah ama saliid yar, yaraynta kharashka dayactirka alaabta. Tusaale ahaan, polyoxymethylene (POM) balaastikada injineernimada waxay leeyihiin iska caabin aad u fiican oo xirashada waxaana loo yaqaanaa “bir caag ah”, kaas oo si weyn loogu isticmaalo soo saarista qalabka baabuurta, qaybaha korantada iyo qaybaha kale ee u adkaysta xidhashada.

2. Farsamada Habaynta Muhiimka ah ee Caagagga Injineerinka: Teknolojiyadda Twin-Screw Extrusion Extrusion

Farsamaynta balaastikada injineernimada inta badan waxaa ka mid ah extrusion, injection molding, dharbaaxo, qaabaynta iyo hababka kale, kuwaas oo ka mid ah tignoolajiyada mataanaha-screw extrusion-ka ayaa ah tignoolajiyada udub-dhexaadka u ah soo saarista xeryahooda caagga ah ee injineernimada (sida balaastikada injineernimada oo la beddelay, balaastikada injineernimada ee la xoojiyay) iyo alaabta dhammaatay (sida tuubooyinka, go'yaal, fiilooyinka). Marka la barbar dhigo tignoolajiyada extrusion-ka-fure, twin-screw extrusion technology has the advantages of strong shearing force, good mixing effect, precise temperature control, short residence time and strong adaptability to raw materials, which can effectively solve the processing difficulties of engineering plastics (such as sensitivity to overheating and hydrolytic degradation, poor mixing effect, low processing efficiency) and ensure the quality of engineering plastic products.

2.1 Processing Difficulties of Engineering Plastics and Requirements for Extrusion Equipment

As mentioned earlier, engineering plastics have excellent comprehensive performance, but their processing difficulty is also higher than that of general plastics, mainly due to their special molecular structure and performance characteristics. Dhibaatooyinka farsamaynta ugu weyn ee balaastikada injineernimada iyo shuruudaha u dhigma ee qalabka extrusion waa sida soo socota:

2.1.1 Xasaasiyadda kulaylka xad dhaafka ah iyo xaalufinta Hydrolytic

Inta badan balaastikada injineernimada (sida PA, PBT, PPS) waxay u nugul yihiin kulaylka iyo xaalufka hydrolytic. Haddii heerkulka habayntu aad u sarreeyo ama wakhtiga deggenaanshaha ee extruder uu aad u dheer yahay, silsiladda molecular ee balaastikada injineernimada ayaa jebin doonta, taasoo keentay in kulaylku xumaado, taas oo hoos u dhigi doonta sifooyinka farsamada, iska caabinta kulaylka iyo waxqabadka kale ee alaabta, oo xataa keena midab-doorsoon, carbonization iyo cilladaha kale. In addition, balaastikada injineernimada qaarkood (sida PA) leeyihiin nuugista biyaha sare, iyo qoyaanka ku jira maaddadu waxay sababi doontaa nabaad-guurka hydrolytic inta lagu jiro habka heerkulku sareeyo, saameeya tayada alaabta.

Tani waxay soo bandhigaysaa laba shuruudood oo muhiim ah oo loogu talagalay qalabka extrusion: marka hore, awoodda xakamaynta heerkulka saxda ah, kaas oo si adag u xakameyn kara heerkulka ka shaqeynta gudaha xadka ugu fiican ee balaastikada injineernimada, iska ilaali kulaylka deegaanka, iyo saxnaanta xakamaynta heerkulku waa inay gaadho ±1 ℃; labaad, waqti gaaban oo deggenaansho, taas oo yarayn karta wakhtiga ay walaxdu ku sii jirto foostada extruder-ka, iska ilaali burburka kulaylka iyo xaalufka hydrolytic. Twin-screw extruders waxay leeyihiin faa'iidooyinka wakhtiga degenaanshaha gaaban (sida caadiga ah 1-5 daqiiqado) iyo xakamaynta heerkulka saxda ah, kuwaas oo aad ugu habboon farsamaynta balaastiigga injineernimada marka loo eego kuwa hal-screw extruders ah (wakhtiga degenaanshaha 5-10 daqiiqado).

2.1.2 Shuruudaha Sare ee Saamaynta Isku-dhafka iyo Kala-firdhinta

In farsamaynta balaastikada injineernimada, inta badan waa lagama maarmaan in lagu daro beddelayaasha (sida fiber galaas ah, fiber carbon, talc, ololka celinaya, waafaqsan) si loo hagaajiyo waxqabadka alaabta (sida xoojinta, adkaynaya, olol celin). Tusaale ahaan, 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, samee wax-ka-beddelayaasha si isku mid ah ugu kala firdhisan yihiin matrixka caagga ah ee injineernimada, oo hubi saamaynta isku-dhafka iyo kala-firdhinta. In addition, naqshadeynta moodeelka ah ee mataanaha-maqaarka ayaa si xor ah isugu dari kara walxaha kala duwan ee kala duwan (sida walxaha gudbinta, walxaha isku dhafan, xubno xiirid) iyadoo loo eegayo nooca injineernimada balaastikada iyo beddelka, sii wanaajinta saamaynta isku dhafka iyo kala firdhinta.

2.1.3 Shuruudaha Sare ee u adkaysiga Dharka ee Qalabka

In farsamaynta balaastikada injineernimada la xoojiyay (sida fiber galaas oo la xoojiyay PA, Kaarboonka la xoojiyay PPS), fiber galaas lagu daray, fiber carbon iyo wax ka beddelayaasha kale waxay leeyihiin qallafsanaan sare, Kaas oo sababi doona daal halis ah oo ku dhaca furka iyo foosto dabada inta lagu jiro habka extrusion. Haddii furka iyo foostada ay leeyihiin caabbinta xidhashada liidata, dhaqso ayaa loo gashan doonaa, resulting in reduced shearing force and mixing capacity of the extruder, affecting the product quality and reducing the service life of the equipment.

This requires the screw and barrel of the extruder to be made of high-quality wear-resistant materials and processed by advanced manufacturing technology. Our HTS series extruders adopt imported wear-resistant alloy steel for the screw and barrel, and undergo bimetallic composite treatment or laser cladding treatment, which greatly improves the wear resistance and corrosion resistance of the screw and barrel, and can adapt to the processing of reinforced engineering plastics with high hardness modifiers.

2.1.4 High Requirements on Processing Fluidity and Pressure Control

Some engineering plastics (such as PPS, DAAWO) have high viscosity and poor processing fluidity, which require the extruder to have strong conveying capacity and pressure control capacity to ensure the smooth progress of extrusion. If the conveying capacity is insufficient or the pressure control is unstable, it will cause uneven extrusion speed, unstable product size, and even equipment blockage.

Twin-screw extruders have strong conveying capacity and stable pressure control capacity. The intermeshing of the twin screws can generate strong pumping force, which can effectively convey high-viscosity engineering plastic materials; isla markaasna, the extruder is equipped with a high-precision pressure sensor, which can monitor the extrusion pressure in real time and adjust the screw speed and feeding speed automatically to ensure the stability of the extrusion pressure and the smooth progress of processing.

2.2 Working Principle and Process Flow of Engineering Plastics Twin-Screw Extrusion

The twin-screw extrusion process of engineering plastics is a complex physical and chemical process, kaas oo ku lug leh isdhexgalka arrimo badan sida heerkulka, cadaadis, xoog xiirid iyo waqti. The core purpose is to melt and plasticize the engineering plastic raw materials and modifiers, mix them uniformly, and then extrude them into the required shape (such as particles, tuubooyinka, go'yaal, fiilooyinka) through the die head. Mabda'a shaqada gaarka ah iyo socodka geedi socodka waa sida soo socota:

2.2.1 Raw Material Pretreatment

Raw material pretreatment is the foundation of engineering plastics extrusion processing, which directly affects the processing effect and product quality. The raw materials of engineering plastics mainly include engineering plastic resin (sida PA, PC, POM), modifiers (sida fiber galaas ah, fiber carbon, talc, ololka celinaya), waafaqsan, lubricants and other additives. The pretreatment steps are as follows:

• Drying Treatment: Inta badan balaastikada injineernimada (sida PA, PBT, PPS) leeyihiin nuugista biyaha sare, 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). Sidaa darteed, the raw materials must be dried before processing. The drying temperature and time are determined according to the type of engineering plastic: tusaale ahaan, PA6 is dried at 80-100℃ for 4-6 saacadood, PA66 is dried at 100-120℃ for 6-8 saacadood, PBT is dried at 120-140℃ for 2-4 saacadood, PPS is dried at 150-160℃ for 3-5 saacadood. 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. Xawaaraha isku dhafka ah waa guud ahaan 800-1200 rpm, iyo wakhtiga isku darka waa 5-10 daqiiqado. 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 (sida fiber galaas ah), 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 Feeding and Conveying

The premixed raw materials are sent to the feeding hopper of the twin-screw extruder through a screw feeder or a belt feeder. Aaladda quudinta ee fidiyaha ayaa sida caadiga ah ku qalabaysan habaynta xawaaraha beddelka soo noqnoqda, which can adjust the feeding speed according to the screw speed and extrusion speed to ensure that the materials enter the extrusion cavity stably and uniformly, avoiding material accumulation or insufficient feeding. The feeding hopper is also equipped with a drying device to prevent the raw materials from absorbing moisture again during feeding.

2.2.3 dhalaalay, Mixing and Shearing

Alaabta soo gasha godka extrusion ee fuqarada mataanaha ah waxaa hore u sii riixaya iskoorada wareega. Godka ka soo baxa wuxuu ka kooban yahay fur iyo foosto, iyo mugga daloolka extrusion ayaa si tartiib tartiib ah hoos ugu dhacaya jihada dhidibka. Marka boolalku wareegaan, Qalabka si tartiib tartiib ah ayaa loo cadaadiyaa iyadoo la raacayo ficilka boolal iyo foosto, iyo cadaadiska godka extrusion si tartiib tartiib ah u kordho (guud ahaan 5-15MPa).

Isla markaana, Alaabada waxaa lagu sakhiray xoog xiirid xoog leh iyo xoog is jiid jiid ka dhashay dhaqdhaqaaqa qaraabada ah ee u dhexeeya boolal iyo foosto, iyo sidoo kale inta u dhaxaysa duullimaadyada wareegyada. Xoogga xiiraya iyo xoogga is jiid-jiidka ayaa si buuxda u jebin kara agglomerates-ka beddelayaasha, samee wax-ka-beddelayaasha si isku mid ah ugu kala firdhiyaan resinka caagga ah ee injineernimada, iyo kor u qaadida fiyuuska iyo iswaafajinta ka dhexeeya beddelka iyo resinka. Xoogga is jiid jiidku wuxuu kaloo dhalin karaa xaddi kuleyl ah, which is combined with the external heating of the barrel (electric heating or steam heating) to make the engineering plastic resin gradually melt and plasticize.

The barrel of the extruder is usually divided into 4-6 temperature control sections (feeding section, melting section, mixing section, homogenizing section, dhiman madaxa qaybta), and the temperature of each section is precisely controlled according to the type of engineering plastic. Tusaale ahaan, when processing PA66+GF30 (glass fiber reinforced PA66), the temperature of the feeding section is 120-140℃, the melting section is 250-260℃, the mixing section is 260-270℃, the homogenizing section is 250-260℃, and the die head section is 240-250℃. The precise temperature control can ensure that the resin is fully melted without thermal decomposition, wax ka beddelayaashuna si isku mid ah ayaa loo kala firdhiyey.

2.2.4 Bixinta iyo Qaabaynta

Si buuxda u dhalaalay, Walxaha isku dhafan iyo kuwa kala firdhiyey ayaa lagu riixaa madaxa dhinta ee kaxeeyaha by boolal. Madaxa dhinta waxaa loo qaabeeyey si waafaqsan qaabka alaabta ugu dambeysa: wax soo saarka injineernimada xeryahooda caag ah (granules), madaxa dhimashadu waxay ku qalabaysan tahay godad dhiman oo wareeg ah oo badan (tirada iyo cabbirka godadka dhinta waxaa lagu go'aamiyaa iyadoo loo eegayo cabbirka qayb ka mid ah granules); wax soo saarka tuubooyinka, go'yaal, fiilooyinka, madaxa dhiman waxaa loo qaabeeyey qaabab u dhigma (sida wareegtada ku dhinta tuubooyinka, guri ku dhiman go'yaal).

Maaddada ayaa laga soo saaraa madaxa dhinta si xawli sare leh si loo sameeyo alaab-dhammeedka joogtada ah (sida strips for granules, tuubooyinka, go'yaal). Heerkulka madaxa dhimashadu wax yar ayuu ka hooseeyaa kan qaybta isku midka ah, 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 Qaboojinta iyo adkaynta

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 daqiiqado; 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 (granules), 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, caabbinta kulaylka, saxnaanta cabbirka) 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, inta badan ay ku jiraan sifooyinka alaabta ceeriin, saamiga formula, saamaynta premixing, xuduudaha extrusion iyo dhinta qaab-dhismeedka madaxa. 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 Astaamaha Qalabka Ceyriinka

Nooca, cabbirka walxaha, moisture content and purity of raw materials have a great impact on the extrusion effect. Tusaale ahaan, 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. Nadiifinta alaabta ceeriin sidoo kale waa mid aad muhiim u ah; wasakhda alaabta ceeriin (sida biraha, dhagxaan, siigada) kaliya ma saameyn doonto tayada alaabta, laakiin sidoo kale xidho furka iyo foosto ee daba-dheeraha, oo xitaa sababa xannibaadda qalabka.

2.3.2 Saamiga Formula

saamiga formula ee xeryahooda caag injineernimada (saamiga xabagta, wax ka beddelka iyo waxyaabaha lagu daro) waa furaha lagu go'aaminayo waxqabadka alaabta. Nooca iyo qiyaasta beddelayaasha waa in lagu go'aamiyaa iyadoo loo eegayo shuruudaha waxqabadka alaabta. Tusaale ahaan, ku daray 20%-40% fiber galaas ah ilaa PA waxay si weyn u wanaajin kartaa xooggeeda iyo xasilloonida cabbirkeeda, laakiin fiber-ka galaaska ee xad-dhaafka ah ayaa yarayn doona adkaanta iyo habaynta dareeraha alaabta. Nooca iyo qiyaasta waxyaabaha lagu daro waxay sidoo kale u baahan yihiin in si macquul ah la isku waafajiyo: is-waafajiyayaashu waxay wanaajin karaan is-waafajinta ka dhexeeya beddelayaasha iyo resinka, iyo qiyaasta guud ahaan waa 0.5%-2%; Saliidaha ayaa yarayn kara khilaafka u dhexeeya alaabta iyo qalabka, hagaajinta dareeraha ka shaqaynta, iyo qiyaasta guud ahaan waa 0.3%-1%; antioxidants waxay ka hortagi karaan walxaha hoos u dhaca oksaydhka kulaylka inta lagu jiro farsamaynta, iyo qiyaasta guud ahaan waa 0.1%-0.5%.

2.3.3 Saamaynta Premixing

Premixing waa aasaaska farsamaynta extrusion. Isku-duubnida premixing waxay si toos ah u saamaysaa isku darka iyo kala firdhinta wax-ka-beddelayaasha inta lagu jiro extrusion. Haddii premixingku aanu sinnayn, wax ka beddelayaashu si isku mid ah looguma dhejin karo dusha sare ee resinka, taasoo keentay in maxalli ah oo wax ka beddelo, isku darka aan sinnayn ee alaabta inta lagu jiro extrusion, iyo hoos u dhaca waxqabadka alaabta. Si loo hubiyo saamaynta premixing, waa lagama maarmaan in la xakameeyo xawaaraha isku dhafka, waqtiga isku dhafka iyo heerkulka isku dhafka: xawaaraha isku dhafka ah waa 800-1200 rpm, waqtiga isku darka waa 5-10 daqiiqado, and the mixing temperature is controlled at 40-60℃ (appropriate temperature can improve the adhesion of additives and promote uniform mixing).

2.3.4 Extrusion Parameters

Extrusion parameters are the most important factors affecting the extrusion effect, mainly including screw speed, extrusion temperature and extrusion pressure.

• Xawaaraha isku dubaridka: The screw speed of twin-screw extruders for engineering plastics generally ranges from 100 ku 1000 rpm. Our HTS series extruders can reach a maximum speed of 1000 rpm. The higher the screw speed, the greater the shear force and friction force received by the materials, the better the mixing and dispersing effect of modifiers, and the higher the production efficiency. Si kastaba ha ahaatee, if the screw speed is too high, the residence time of the materials in the extrusion cavity is too short, resulting in incomplete melting of the resin, insufficient mixing of materials, and uneven product quality; haddii xawaaruhu aad u yar yahay, xoog-xiirid iyo xoog is jiid-jiidku kuma filna, the modifiers cannot be fully dispersed, waxtarka wax-soo-saarkuna wuu hooseeyaa. The screw speed should be adjusted according to the type of engineering plastic and the type of modifier: for high-viscosity engineering plastics (such as PPS, DAAWO), a lower screw speed is needed to ensure sufficient melting and mixing; for reinforced engineering plastics (sida fiber galaas oo la xoojiyay PA), a higher screw speed is needed to ensure the uniform dispersion of glass fiber.
• Heerkulka ka soo baxa: The extrusion temperature is the key to ensuring the melting and plasticization of engineering plastics. Heerkulka qayb kasta oo foosto ah iyo madaxa dhinta waa in si sax ah loo xakameeyaa iyadoo loo eegayo nooca caaga injineernimada. Heerkulka qaybta quudinta ayaa hooseeya (wax yar ka sarreeya heerkulka qalajinta ee alaabta ceeriin), Kaas oo inta badan ah in laga ilaaliyo agabka in ay dubtaan iyo in la hubiyo quudin siman; heerkulka qaybta dhalaalidu waa dhexdhexaad, Kaas oo inta badan ah in kor loo qaado dhalaalka iyo balaastigga resinka; heerkulka qaybta isku dhafka ayaa sarreeya, Kaas oo inta badan kor loogu qaado xiirta iyo saamaynta isku dhafka ah, iyo kor u qaadida kala firdhinta yunifoomka ee beddelayaasha; heerkulka qaybta homogenizing ayaa wax yar ka hooseeya qaybta isku dhafka, taas oo inta badan ah in la hubiyo heerkulka isku midka ah iyo viscosity ee alaabta, iskana ilaali burburka kulaylka; heerkulka qaybta madaxa dhimashadu wax yar ayuu ka hooseeyaa qaybta isku-darka, taas oo ah in la hubiyo saamaynta qaabaynta ee alaabada dhammaatay. Saxnaanta xakamaynta heerkulku waa inay gaadho ± 1 ℃ si looga fogaado kulaylka deegaanka iyo kulaylka walxaha.
• Cadaadiska Soo Bixinta: Cadaadiska extrusion ee injineernimada balaastikada mataanaha-screw extrusion guud ahaan waa ka 5 ilaa 15MPa. Cadaadiska ku jira godka extrusion waxaa inta badan lagu go'aamiyaa saamiga isku-buufinta ee furaha, cabbirka godka dhinta iyo xawaarihiisa isku dhufashada. Cadaadiska extrusionka ayaa sarreeya, sida ugu wanagsan ee isku dhafka iyo kala firdhinta agabka, iyo cufan alaabta. Si kastaba ha ahaatee, haddii cadaadisku aad u sarreeyo, waxay kordhin doontaa isticmaalka tamarta iyo xirashada qalabka, oo xitaa sababa in madaxa dhiman uu xannibo; 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 (granules), 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, iyo kanaalka qulqulka madaxa dhimashadu waa inuu ahaadaa mid siman si looga fogaado isku-ururinta walxaha iyo kulaylka maxalliga ah. Madaxa dhimashadu waa in lagu rakibaa qalabka xakamaynta heerkulka si loo hubiyo heerkulka isku midka ah ee madaxa dhinta iyo qaabeynta xasilloon ee alaabta.

3. Extrudersyada Taxanaha HTS: Xalka Xirfadlaha ee farsamaynta Caagagga Injineerinka

Waxaan muddo dheer ku hawlanayn cilmi-baarista, horumarinta iyo soo saarista wax-qabadka sare ee twin-screw extruders, oo ay soo ururiyeen khibrad qani ah oo ku saabsan farsamaynta balaastikada injineernimada. Sida laga soo xigtay sifooyinka processing ee balaastikada injineernimada (u nugul kulaylka iyo xaalufka hydrolytic, shuruudaha sare ee isku dhafka iyo saamaynta kala firdhiyey, viscosity sare) iyo baahida codsiga, we have developed the HTS series twin-screw extruders specially for engineering plastics processing. Our HTS series extruders adopt high-torque gearboxes, with a specific torque of 14Nm/cm³ and a maximum speed of up to 1000rpm, which can obtain higher output, shorter residence time, better dispersibility and more precise temperature control, perfectly adapting to the processing needs of various engineering plastics.

3.1 Core Advantages of HTS Series Extruders for Engineering Plastics Processing

3.1.1 High Torque and High Speed, High Production Efficiency

Engineering plastics have high viscosity and poor processing fluidity, which require the extruder to have strong torque and conveying capacity. Our HTS series extruders adopt high-torque gearboxes independently developed and manufactured by us (HTS PLUS series and HTS SUPER series) ama laga keeno shirkadaha hormuudka ka ah Yurub (Taxanaha HTS AASAASIGA AH), oo leh wareeg gaar ah oo ah 14Nm/cm³, kaas oo aad uga sarreeya kan caadiga ah ee mataanaha-screw extruders (Wareegga guud waa 8-12Nm/cm³). Naqshadaynta qulqulka sare waxay hubisaa in bakhtiiyehu uu si deggan u gudbin karo qalabyada caagagga ah ee injineernimada sare leh, iska ilaali ururinta alaabta iyo xannibaadda qalabka, iyo hagaajinta xasiloonida habka extrusion.

Isla markaana, extruders taxane HTS leeyihiin design xawaaraha sare, Xawaaraha ugu badan ee ilaa 1000rpm. Xawaaraha sare wuxuu dhalin karaa xoog xiirid xoog leh iyo xoog isku dhafan, which can fully break the agglomerates of modifiers, samee wax-ka-beddelayaasha si isku mid ah ugu kala firdhisan shaxanka xabagta, iyo hagaajinta isku dhafka iyo kala firdhinta. In addition, naqshadeynta xawaaraha sare waxay sidoo kale si weyn u wanaajisaa waxtarka wax soo saarka: marka la barbardhigo extruders caadiga ah, the production efficiency of HTS series extruders can be increased by 30%-50%, which can meet the large-scale production needs of engineering plastics enterprises.

3.1.2 Short Residence Time, Effectively Avoiding Thermal Degradation

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 daqiiqado, which is much shorter than that of ordinary twin-screw extruders (5-10 daqiiqado) and single-screw extruders (10-15 daqiiqado). 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, which can further adjust the residence time of the material, ensuring that different types of engineering plastics can obtain the optimal residence time during processing.

3.1.3 Precise Temperature Control, Stable Performance

The HTS series extruders adopt an advanced intelligent temperature control system, which can realize precise control of the temperature of each section of the barrel and the die head. The temperature control precision can reach ±1℃, kaas oo si adag u xakameyn kara heerkulka ka shaqeynta gudaha xadka ugu fiican ee balaastikada injineernimada, avoid local overheating and thermal decomposition of the material. The temperature control system is equipped with a real-time monitoring and alarm function: if the temperature of any section exceeds the set range, the system will issue an alarm prompt in time, and even automatically adjust the heating power or shut down the equipment if necessary, to avoid equipment failure and product quality problems.

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. Is-dhex-galka iyo wareegitaanka furayaasha mataanaha ah waxay dhalin karaan xoog xiirid xoog leh iyo xoog cajiin, which can fully break the agglomerates of modifiers (sida fiber galaas ah, fiber carbon, talc), samee wax-ka-beddelayaasha si isku mid ah ugu kala firdhiyaan matrix caagagga injineernimada, oo hubi saamaynta isku-dhafka iyo kala-firdhinta. Isku-dhafka isku-dhafka ah ee HTS-ka-baxayaasha taxanaha ah ayaa gaari kara in ka badan 95%, kaas oo aad uga sarreeya kan caadiga ah ee mataanaha-screw extruders (85%-90%).

Kaashashka taxanaha HTS extruders wuxuu qaataa naqshad qaabaysan, iyo nuucyada kala duwan ee walxaha isbiirsada (sida walxaha gudbinta, walxaha isku dhafan, xubno xiirid) si xor ah ayaa loo isku dari karaa iyadoo loo eegayo nooca injineernimada balaastikada iyo beddelka. Tusaale ahaan, marka la farsameeyo balaastikada injineernimada ee la xoojiyay oo leh fiber galaas ah, Waxyaalo badan oo xiirid ah ayaa loo qaabayn karaa si kor loogu qaado saamaynta dhogorta iyo in la hubiyo kala firdhisanaanta isku midka ah ee fiber galaas; marka la farsameeyo balaastikada injineernimada oo leh viscosity sare (such as PPS), Waxyaalo badan oo isku dhafan ayaa la habeyn karaa si loo hagaajiyo saameynta isku-dhafka iyo in la hubiyo viscosity lebbiska ee walxaha.

3.1.5 Iska caabinta Dharka Sare, Nolosha Adeegga Dheer

In farsamaynta balaastikada injineernimada la xoojiyay (sida fiber galaas oo la xoojiyay PA, Kaarboonka la xoojiyay PPS), wax-beddelayaasha lagu daray waxay leeyihiin qallafsanaan sare, Kaas oo sababi doona daal halis ah oo ku dhaca furka iyo fuustada dabada. Extrudersyada taxanaha ah ee HTS waxay qaataan agab tayo sare leh oo u adkaysta xidhashada iyo tignoolajiyada wax soo saarka ee horumarsan si loo hubiyo caabbinta xidhashada qaybaha aasaasiga ah.

furka iyo foosto ee taxanaha HTS extruders waxay ka samaysan yihiin bir daawaha adkaysta xidho dibadda ah (sida 38CrMoAlA), and undergo bimetallic composite treatment or laser cladding treatment. Adkeydka dusha sare ee furka iyo foosto waxay gaari karaan ≥65 HRC (Taxanaha HTS AASAASIGA AH) iyo ≥70 HRC (HTS PLUS series and HTS SUPER series), kaas oo leh iska caabbinta xidhashada iyo iska caabinta daxalka, waxayna si wax ku ool ah u diidi kartaa xirashada ay sababto wax ka beddelayaasha adag ee adag. Tani waxay si weyn u kordhisaa nolosha adeegga furka iyo foosto: nolosha adeegga furka iyo foosto ee extruders taxane HTS waa 2-3 times that of ordinary extruders, reducing the frequency of component replacement and the maintenance cost of the equipment.

In addition, Waxaan sidoo kale bixinaa adeegyo ogaanshaha xirashada xirfadlayaasha ah ee furka iyo foosto. Kooxdayada farsamo ayaa si joogto ah u ogaan doona heerka xidhashada ee furka iyo foosto ee macaamiisha, soo saar warbixin dharbaaxo faahfaahsan, waxayna soo bandhigeen talooyinka dayactirka iyo beddelka bartilmaameedka ah, ensuring that customers only replace components when necessary, avoiding unnecessary waste.

3.1.6 Wide Application Range, Strong Flexibility

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, PC, POM, PET, PBT) and special engineering plastics (PPS, DAAWO, PSU, PES). The extruders can also adapt to the processing of various modified engineering plastics, sida balaastikada injineernimada ee la xoojiyay (fiber galaas xoojiyay, fiber carbon xoojiyay), balaastikada injineernimada adag, balaastikada injineernimada ololka, balaastikada injineernimada antistatic, iwm.

Naqshadaynta qaab-dhismeedka taxanaha HTS extruders (isku dhufasho, foosto, madaxa dhiman, iwm.) wuxuu ka dhigayaa beddelka qaybaha mid ku habboon oo degdeg ah. Marka macaamiishu u baahan yihiin inay hagaajiyaan nooca alaabta (sida ka beddelka habaynta PA una beddelo habaynta PPS) ama wax ka beddel qaacidada, kaliya waxay u baahan yihiin inay bedelaan qaybaha u dhigma, iyada oo aan la beddelin dhammaan qalabka, taas oo hoos u dhigaysa qiimaha isbeddelka qalabka iyo hagaajinta dabacsanaanta iyo la qabsiga qalabka.
