Masterbatch Advanced Twin-Screw Extrusion Technology Applications and Comprehensive Processing Solutions

1. Overview of Masterbatch Industry and Core Knowledge

1.1 Current Situation and Development Trend of Masterbatch Industry

Masterbatch, also known as color masterbatch or color concentrate, is a new type of plastic coloring material with high concentration, high dispersibility and convenient use. It is made by uniformly dispersing pigments or dyes, carriers and additives in a specific proportion through professional mixing and extrusion granulation technology. Compared with the traditional direct coloring method (directly adding pigments to plastic raw materials), masterbatch has the advantages of convenient use, uniform coloring, errendimendu egonkorra, environmental protection and energy saving, koloreztatze-metodo tradizionala pixkanaka ordezkatu eta plastikoen industrian koloratzaileen soluzio nagusia bihurtu da.

Azken urteotan, Beheko industrien garapen azkarrak bultzatuta, hala nola ontziratzeak, automobilgintza, ehunak, elektronika, eraikuntza eta etxetresna elektrikoak, masterbatch-en merkatu globalak hazkunde-joera etengabea eta azkarra erakutsi du. Industriari dagozkion datuen arabera, masterbatch-en merkatuaren tamaina gainditu du 30 mila milioi dolar AEB, eta urteko hazkunde-tasa konposatua mantentzea espero da 6%-8% hurrengo bost urteetan. Horien artean, Asia-Pazifikoa munduko masterbatch ekoizpen eta kontsumo merkatu handiena da, baino gehiago kontabilizatuz 60% merkatu globalaren kuota, batez ere Txinan plastikoen industriaren garapen azkarraren ondorioz, India eta beste herrialde batzuk, industria euskarri-gaitasunaren etengabeko hobekuntza, and the increasing demand for high-quality, functional and environmentally friendly masterbatch products.

Txina, as the world’s largest masterbatch producer and consumer, has a huge market demand and a complete industrial chain. The annual output and consumption of masterbatch are growing at a double-digit rate, especially in the fields of new energy vehicles, green packaging, high-end textiles and medical devices, the demand for high-performance masterbatch (such as high-temperature resistant masterbatch, flame-retardant masterbatch, environmental protection masterbatch) is showing an explosive growth trend. With the continuous improvement of global environmental protection policies (such as the ban on toxic and harmful pigments) and the upgrading of consumer demand for high-quality plastic products, masterbatch industria pixkanaka kontzentrazio handirantz garatzen ari da, sakabanagarritasun handia, funtzionalizazioa, ingurumenaren babesa eta adimena.

Masterbatch industriaren garapen joera nagusiak lau alderditan islatzen dira: lehenik, ingurumena babestea eta toxikotasun txikia. Ingurumena babesteko kontzientzia indartuz eta ingurumena babesteko politiken zorroztasunarekin, ez-toxikoak, kaltegabea, ingurumena babesteko lurrunkortasun baxuko eta degradagarria den masterbatch merkatuko nagusi bihurtuko da, eta pigmentu toxiko eta kaltegarriak (hala nola, metal astuneko pigmentuak) pixkanaka ezabatuko da; bigarrena, funtzionalizazioa. Margotzeaz gain, masterbatch integrazio funtzionalaren bidean ere garatzen ari da, hala nola, suaren aurkako masterbatch, masterbatch antiestatikoa, bakterioen aurkako masterbatch, UV erresistentea den masterbatch, which can meet the special use requirements of downstream products; third, high concentration and high dispersibility. High-concentration masterbatch can reduce the addition amount, reduce production costs, and high dispersibility can ensure uniform coloring of plastic products, avoid color spots and color difference, which is the key to improving product quality; fourth, intelligence and automation of processing. Masterbatch processing requires strict control of mixing uniformity, temperature and other parameters. Intelligent, automatic twin-screw extrusion production lines will become the mainstream, realizing real-time monitoring, automatic parameter adjustment and mass production, improving production efficiency and product consistency.

As the core processing equipment of masterbatch, twin-screw extruders play a crucial role in the development of the masterbatch industry. Masterbatch mixing has strict requirements on the mixing and dispersing effect, temperature control and production efficiency of extruders. Zhuoyue’s full series of extruders (HTS BASIC/PLUS/SUPER, ZTE, HTE) are specially designed for masterbatch processing, with targeted performance advantages, which can effectively meet the processing needs of different types of masterbatch and help manufacturers improve product quality and production efficiency.

1.2 Core Composition and Working Principle of Masterbatch

Masterbatch is composed of three basic elements: pigments or dyes, carriers and additives. The proportion and performance of each element directly determine the quality and use effect of masterbatch. Masterbatch-en oinarrizko konposizioa eta lan-printzipioa ulertzea bere prozesatzeko teknologia menderatzeko eta estrusio-ekipo egokia aukeratzeko oinarria da..

1.2.1 Pigmentuak edo koloratzaileak: Core koloreztatzeko osagaia

Pigmentuak edo koloratzaileak dira masterbatch koloreztatzearen errendimendua ematen duten oinarrizko osagaiak, kontabilitatea 10%-80% masterbatch-aren konposizioarena (proportzio espezifikoa pigmentu motaren araberakoa da, kolore-eskakizunak eta masterbatch-en kontzentrazioa). Pigmentuak pigmentu organikoetan eta pigmentu inorganikoetan banatzen dira: pigmentu organikoek kolore biziak dituzte, tindatzeko indar handia, gardentasun ona, baina beroarekiko erresistentzia eta eguraldiarekiko erresistentzia eskasa, batez ere, tenperatura baxuko plastikoetan erabiltzen da (hala nola, LH, PP) eta kolore eskakizun handiak dituzten produktuak (hala nola ehungintza, ontziratzeko filmak); pigmentu ez-organikoek beroarekiko erresistentzia ona dute, eguraldiaren erresistentzia eta egonkortasun kimikoa, baina tindatze-indar baxua eta gardentasun eskasa, batez ere tenperatura altuko plastikoetan erabiltzen da (esaterako, ingeniaritza plastikoak) eta kanpoko produktuak (hala nola, eraikuntzako materialak, automobilen kanpoko piezak).

Tindagaiak pigmentuetatik desberdinak dira. Koloreek disolbagarritasun ona dute plastikozko lehengaietan, kolore biziak eta gardentasun handia, baina beroarekiko erresistentzia eta argiarekiko erresistentzia eskasa, batez ere plastikozko produktu gardenetan erabiltzen da (esaterako, PET botilak, PC fitxak). Pigmentuen edo koloratzaileen aukeraketa plastikozko lehengai motaren arabera egin behar da (prozesatzeko tenperatura), produktuak erabiltzeko ingurunea (barne/kanpo), koloreztatzeko baldintzak (kolore distira, gardentasuna) eta ingurumena babesteko baldintzak, masterbatch-ak kolore-errendimendu egonkorra duela eta beheranzko produktuen erabilera-eskakizunak betetzen dituela ziurtatzeko.

1.2.2 Garraiolariak: Dispertsioaren eta atxikimenduaren osagaia

Eramaileak masterbatch-aren matrizea dira, kontabilitatea 10%-80% masterbatch-aren konposizioarena, batez ere, pigmentuak/koloratzaileak barreiatzeko eta plastikozko lehengaiei atxikitzeko papera jokatuz. Eramaileak bateragarritasun ona izan behar du pigmentu/koloratzaileekin eta xede plastikozko lehengaiekin (koloreztatu beharreko plastikozko lehengaiak), bestela, pigmentuen sakabanaketari eta produktuen kolore-efektuari eragingo dio. Eramaile arrunteko materialak polietilenoa dira (LH), polipropilenoa (PP), polibinilo kloruroa (PVCa), poliamida (PA), polietileno tereftalatoa (PET), etab., xede plastikozko lehengai motaren arabera hautatzen direnak: adibidez, PE eramailea PE plastikozko koloreetarako erabiltzen da, PP eramailea PP plastikozko koloreetarako erabiltzen da, eta PA eramailea plastikozko PA koloreztatzeko erabiltzen da.

Eramaileak prozesatzeko jariakortasun ona izan behar du, which is conducive to the uniform dispersion of pigments during extrusion processing and the mixing of masterbatch with target plastic raw materials. Horrez gain, the melting point and processing temperature of the carrier should be consistent with or slightly lower than that of the target plastic raw materials, to avoid the decomposition of the carrier or the target plastic during processing.

1.2.3 Gehigarriak: The Auxiliary Functional Component

Additives are auxiliary components added to improve the processing performance, dispersibility and use performance of masterbatch, kontabilitatea 1%-10% masterbatch-aren konposizioarena. The type and dosage of additives are determined according to the type of masterbatch and processing requirements. Common additives include:

• Dispersants: The most important additive in masterbatch, which can reduce the surface tension of pigments, pigmentu aglomerazioa saihestea, eta eramailean uniformeki sakabanatutako pigmentuak egin. Sakabanatzaile arruntak polietilenozko argizaria dira, polipropilenozko argizaria, azido estearikoa, kaltzio estearatoa, etab. Sakabanatzaileak gehitzeak masterbatch-aren barreigarritasuna nabarmen hobetu dezake, produktuen kolore uniformea ​​bermatzea, eta estrusio-ekipoen higadura murriztea.
• Bateragarriak: Pigmentuen eta eramaileen arteko bateragarritasuna hobetzeko erabiltzen da, eta masterbatch eta xede plastikozko lehengaien artean. Adibidez, Eramaileak eta xede plastikoak bateragarritasun eskasa dutenean (hala nola, PE eramailea eta PA plastikoa), bateragarriak (hala nola, anhidrido maleikoa txertatutako polietilenoa) haien arteko lotura-indarra areagotzeko gehi daiteke, saihestu masterbatch-a eta xede plastikoa bereiztea prozesatzeko garaian, eta produktuen propietate mekanikoak hobetzea.
• Bero-egonkortzaileak: Used to prevent the decomposition of pigments, carriers and target plastics during high-temperature extrusion processing. Common heat stabilizers include lead salts, calcium-zinc stabilizers, organic tin stabilizers, etab., which are selected according to the processing temperature and environmental protection requirements.
• Light Stabilizers and Antioxidants: Used to improve the weather resistance and aging resistance of masterbatch and colored plastic products, prevent the color fading and performance degradation of products under sunlight and oxygen, and extend the service life of products.
• Lubrikatzaileak: Used to reduce the friction between materials and extrusion equipment (torlojua, barrika, burua hil), improve processing fluidity, energia-kontsumoa murriztea, and avoid material sticking to equipment, which is conducive to the smooth progress of extrusion processing.

1.2.4 Working Principle of Masterbatch

The working principle of masterbatch is based on the uniform dispersion of high-concentration pigments in the carrier. During the processing of plastic products, a small amount of masterbatch (usually 1%-5%) is mixed with uncolored plastic raw materials. Under the action of high temperature and shear force during extrusion or injection molding, the carrier of the masterbatch melts and mixes with the target plastic raw materials, and the uniformly dispersed pigments are released and uniformly distributed in the target plastic matrix, thus achieving the purpose of coloring plastic products. The key of this process is that the pigments in the masterbatch must be uniformly dispersed without agglomeration, otherwise it will cause color spots, kolore desberdintasuna eta koloretako produktuen beste akats batzuk.

1.3 Masterbatch-en sailkapen komuna

Masterbatch mota desberdinetan bana daiteke sailkapen estandar ezberdinen arabera, hala nola, kolore mota, eramaile mota, aplikazio eremua, mota funtzionala, etab.

Tintatzearen indarra, koloreen distira eta kolore masterbatch-aren sakabanagarritasuna bere kalitatea neurtzeko funtsezko adierazleak dira.
• Masterbatch zuria: Titanio dioxidoa erabiliz (TiO2) koloreko osagai nagusi gisa, plastikozko produktuak zuritzeko edo kolore argiko masterbatchrako oinarrizko kolore gisa erabiltzen da. Zuritasuna, masterbatch zuriaren boterea eta sakabanaketa estaltzea dira adierazle nagusiak. Titanio dioxidoak gogortasun handia du, Estrusio-ekipoen higadura-erresistentziari buruzko baldintza handiak dituena.
• Masterbatch beltza: Kolore-osagai nagusi gisa karbono beltza erabiltzea, plastikozko produktuen kolore beltzeko erabiltzen da. Karbono beltzak UV erresistentzia ona eta eguraldiaren erresistentzia du, eta plastikozko produktuen propietate mekanikoak ere hobetu ditzake. Karbono beltzaren sakabanagarritasuna masterbatch beltzaren kalitatearen gakoa da. Sakabanagarritasun eskasak orban beltzak eta marrak eragingo ditu produktuetan.

1.3.2 Garraiolari motaren araberako sailkapena

Eramaile motaren arabera, masterbatch PE masterbatch-etan bana daiteke, PPren masterbatch, PVC masterbatch, PA masterbatch, PET masterbatch, etab.

• LH Masterbatch: LH eramaile gisa erabiltzea, egokia da PE plastikozko produktuak koloreztatzeko (hala nola, LH filmak, PE hodiak, PE injekziozko piezak). PE lehengaiekin bateragarritasun ona du, prozesatzeko jariakortasun ona eta kolore uniformea.

• PVC Masterbatch: PVCa eramaile gisa erabiltzea, PVC plastikozko produktuak koloreztatzeko egokia da (hala nola, PVC hodiak, PVC profilak, PVC filmak). It needs to be matched with PVC heat stabilizers to avoid PVC decomposition during processing.
• Engineering Plastic Masterbatch: Using engineering plastics (PA, PCa, PBT, etab.) as carriers, it is suitable for coloring engineering plastic products (hala nola, automobilgintzako piezak, osagai elektrikoak). It has good heat resistance and compatibility with engineering plastics, and has high requirements on extrusion processing equipment.

1.3.3 Classification by Application Field

According to the application field of masterbatch, it can be divided into fiber masterbatch, film masterbatch, blow molding masterbatch, extrusion masterbatch, injection molding masterbatch, etab., which correspond to the five major application fields of masterbatch.

• Fiber Masterbatch: Used for coloring chemical fibers (such as polyester fiber, nylon fiber), which is used in carpets, ehunak, cushions and other products. It requires high dispersibility and color fastness, and no color fading during spinning and weaving.
• Film Masterbatch: Used for coloring plastic films (such as shopping bags, casting films, multi-layer films), which requires high transparency and uniform coloring, and no color spots or streaks on the film surface.
• Blow Molding Masterbatch: Used for coloring blow molding products (such as medical and cosmetic containers, lubricating oil and paint containers), which requires good processing fluidity and uniform coloring, and no deformation or color difference of the container.

1.3.4 Mota funtzionalaren araberako sailkapena

Masterbatch-en funtzio gehigarrien arabera, masterbatch arruntetan bana daiteke (kolore funtzio bakarra) eta masterbatch funtzionala (koloreztatzea + funtzio osagarriak). Masterbatch funtzionala industriaren garapen joera da, eta ohiko motak suaren aurkako masterbatch dira, masterbatch antiestatikoa, bakterioen aurkako masterbatch, UV erresistentea den masterbatch, masterbatch gogortzea, etab. Masterbatch funtzionalak dagozkien gehigarri funtzionalak gehitzea eskatzen du masterbatch arruntean oinarrituta, Estrusio-ekipoen nahasketa- eta sakabanaketa-efektuan baldintza handiagoak dituena.

2. Masterbatch-en oinarrizko prozesatzeko teknologia: Torloju Bikoitzeko Estrusio Teknologia

Masterbatch-en prozesamenduak nahasketa barne hartzen du batez ere, estrusioa, hoztea, granulazioa eta beste prozesu batzuk, horien artean, torloju bikoitzeko estrusioaren teknologia masterbatch nahasteko eta granulatzeko oinarrizko teknologia da. Torloju bakarreko estrusio-teknologiarekin alderatuta, torloju bikoitzeko estrusio-teknologiak nahasteko eta sakabanatzeko ahalmen sendoaren abantailak ditu, tenperatura kontrol zehatza, egoitza denbora laburra, produkzio-eraginkortasun handia eta lehengaietara moldagarritasun handia, masterbatch prozesatzeko funtsezko arazoak eraginkortasunez ebatzi ditzakeena (hala nola, pigmentu aglomerazioa, nahasketa irregularra, produkzio-eraginkortasun baxua) eta masterbatch produktuen kalitatea bermatzea.

Masterbatch nahasketa torloju biko estrusoreen aplikazio nagusietako bat da. Masterbatch-en kalitatea zuzenean zehazten da torloju biko estrusorearen errendimenduak eta prozesatzeko prozesuaren arrazionaltasunak.. Torloju biko estrusoreetarako masterbatch prozesatzeko funtsezko baldintzak hauek dira: nahasketa eta sakabanaketa efektu indartsua (to ensure uniform dispersion of pigments), tenperatura kontrol zehatza (to avoid pigment decomposition and carrier degradation), appropriate shear force (to break pigment agglomerates without damaging pigment particles), produkzio-eraginkortasun handia (to meet mass production needs) and good wear resistance (to adapt to the wear of high-hardness pigments such as titanium dioxide and carbon black).

2.1 Processing Difficulties of Masterbatch and Requirements for Extrusion Equipment

Although twin-screw extrusion technology is suitable for masterbatch processing, due to the particularity of masterbatch composition (high pigment content, easy agglomeration of pigments) and processing requirements (uniform dispersion, errendimendu egonkorra), there are still many difficulties in actual processing. The main processing difficulties and corresponding requirements for extrusion equipment are as follows:

2.1.1 Pigment Agglomeration and Poor Dispersibility

Pigments (especially inorganic pigments such as titanium dioxide and carbon black) have strong polarity and large specific surface area, which are easy to agglomerate into large particles during storage and mixing. If the agglomerates cannot be fully broken and dispersed during extrusion processing, the masterbatch will have poor dispersibility, and the colored plastic products will have color spots, color streaks and uneven coloring, which will seriously affect the product quality. This is the most common and key difficulty in masterbatch processing.

This requires the extrusion equipment to have strong mixing and dispersing capacity and appropriate shear force. The twin-screw extruder should adopt an intermeshing co-rotating structure, and the screw should be equipped with sufficient mixing elements and shearing elements to generate strong shear force and kneading force during rotation, which can fully break the pigment agglomerates and make the pigments uniformly dispersed in the carrier. Horrez gain, the screw speed and extrusion pressure should be adjustable to adapt to different types of pigments and masterbatch concentrations.

2.1.2 Pigment Decomposition and Carrier Degradation Caused by Overheating

Most pigments (especially organic pigments) have poor heat resistance, and the carrier (hala nola, LH, PP) also has a certain temperature resistance limit. If the extrusion temperature is too high or the residence time of the material in the extruder is too long, the pigment will decompose (resulting in color fading, discoloration), and the carrier will degrade (resulting in reduced mechanical properties of the masterbatch). This is another key difficulty in masterbatch processing.

This requires the extrusion equipment to have precise temperature control capacity and short residence time. The barrel of the extruder should be divided into multiple temperature control sections, and the temperature of each section should be precisely controlled within the optimal range (usually 150-220℃ for ordinary masterbatch, 200-280℃ for engineering plastic masterbatch), with a temperature control precision of ±1℃. The screw structure should be optimized to shorten the residence time of the material in the extruder (usually 1-3 minutuak), avoiding long-term contact between the material and high temperature.

2.1.3 Wear of Screw and Barrel Caused by High-Hardness Pigments

Pigmentu ez-organikoek, hala nola titanio dioxidoa eta karbono beltza, gogortasun handia dute (Mohs gogortasuna 5-7), horrek estrusioaren prozesatzean torlojuari eta kanoi higadura larria eragingo diona. Torlojuak eta kanoiak higadura-erresistentzia eskasa badute, azkar jantziko dira, estrusorearen ebakidura-indarra eta nahaste-ahalmena murriztea ondorioz, masterbatch-aren sakabanagarritasunari eraginez eta ekipoaren zerbitzu-bizitza murriztea.

Honek estrusorearen torlojua eta kanoia kalitate handiko higadura erresistenteak diren materialekin egin behar dira eta fabrikazio teknologia aurreratuarekin prozesatu behar dira.. Adibidez, torlojua eta kanoia inportatutako higadura erresistentea den aleazio altzairuz egin daiteke, eta konposite bimetalikoen tratamendua edo laser bidezko estalduraren tratamendua jasaten dute, horrek asko hobetu dezake torlojuaren eta kanoiaren higadura-erresistentzia eta korrosioarekiko erresistentzia, eta gogortasun handiko pigmentuekin masterbatch-en prozesatzera egokitu.

2.1.4 Loteen arteko produktuaren kalitatearen ezegonkortasuna

Masterbatch prozesatzeak hainbat parametroren kontrol zorrotza eskatzen du (hala nola, formula ratioa, mixing time, extrusion temperature, torlojuaren abiadura, elikadura abiadura). If the parameters fluctuate, the quality of the masterbatch (such as concentration, dispersibility, tinting strength) will be unstable, resulting in color difference between batches of colored products, which will affect the reputation of the manufacturer.

This requires the extrusion equipment to have intelligent control capacity and stable performance. The extruder should be equipped with a PLC intelligent control system, which can realize precise control of feeding speed, torlojuaren abiadura, extrusion temperature and other parameters, and store multiple sets of formula parameters. When producing different batches of masterbatch, only the corresponding parameters need to be called, avoiding repeated debugging, ensuring the stability of product quality between batches.

2.1.5 High Requirements on Processing Fluidity

Masterbatch has high pigment content, which will reduce the processing fluidity of the material. If the processing fluidity is too poor, the material will be difficult to convey and extrude, resulting in low production efficiency, unstable extrusion pressure and even equipment blockage.

This requires the extrusion equipment to have strong conveying capacity and adjustable shear force. The twin-screw extruder should adopt a reasonable screw pitch, lead and compression ratio design, and the screw should be equipped with sufficient conveying elements to ensure the smooth conveying of materials. Horrez gain, the extrusion temperature can be appropriately adjusted to improve the processing fluidity of the material, and lubricants can be added to reduce the friction between materials.

2.2 Working Principle and Process Flow of Masterbatch Twin-Screw Extrusion

The twin-screw extrusion process of masterbatch is a complex physical mixing process, which mainly includes raw material pretreatment, premixing, elikadura, urtzen, mixing and shearing, estrusioa, hoztea, granulazioa, screening and packaging. The core purpose is to uniformly disperse pigments, carriers and additives to form high-quality masterbatch granules. Lan-printzipio espezifikoa eta prozesu-fluxua honako hauek dira:

2.2.1 Lehengaien aurretratamendua

Raw material pretreatment is the foundation of masterbatch extrusion processing, which directly affects the mixing effect and product quality. The raw materials of masterbatch mainly include pigments/dyes, carriers, gehigarriak (dispersants, bateragarriak, heat stabilizers, etab.). Aurretratamenduaren urratsak hauek dira:

• Lehortzeko tratamendua: Some pigments (such as organic pigments) and carriers (hala nola, PA, PET) have high water absorption. If the moisture content is too high, it will cause bubbles, agglomeration and other defects in the masterbatch during extrusion processing, eta baita garraiolariaren degradazio hidrolitikoa eragin ere. Horregatik, lehengaiak prozesatu aurretik lehortu behar dira. Lehortzeko tenperatura eta denbora lehengai motaren arabera zehazten dira: adibidez, pigmentu organikoak 60-80 ℃-tan lehortzen dira 2-4 orduak, PE/PP eramaileak 80-100 ℃-tan lehortzen dira 3-5 orduak, eta PA eramaileak 100-120 ℃-tan lehortzen dira 6-8 orduak. Lehortutako lehengaien hezetasuna behean kontrolatu behar da 0.1%.
• Birrintzea eta bahetzea: Partikula tamaina handiko pigmentuetarako (hala nola, titanio dioxidoaren aglomeratuak) eta partikula tamaina irregularra duten eramaileak, birrintzeko eta bahetzeko tratamendua egin behar da lehengaien uniformetasuna bermatzeko. Birrindutako lehengaien partikulen tamaina at kontrolatu behar da 20-40 sare, which is conducive to the uniform mixing of raw materials and the breaking of pigment agglomerates during extrusion.
• Impurity Removal: The raw materials may contain impurities (such as metal particles, harriak, hautsa) during production and transportation. Impurities not only affect the quality of the masterbatch, baina baita estrusorearen torlojua eta kanoia ere higadura, eta baita ekipoak blokeatzea ere. Horregatik, the raw materials must be filtered and removed before use, using a filter screen with appropriate mesh size to remove impurities.

2.2.2 Premixing

Premixing is the key step to improve the mixing and dispersing effect of masterbatch. According to the formula ratio, the dried, crushed and impurity-removed pigments, carriers and additives are put into a high-speed mixer for premixing. The purpose of premixing is to make the pigments and additives uniformly adhere to the surface of the carrier particles, form a preliminary mixture, eta estrusioan sakabanaketa uniformearen oinarriak ezarri.

Aurrenahasketaren funtsezko parametroak nahasketa abiadura dira, nahasteko denbora eta nahasteko tenperatura. Nahaste-abiadura da, oro har 800-1200 rpm, nahasteko denbora da 5-10 minutuak, eta nahasteko tenperatura 40-60 ℃-tan kontrolatzen da. Nahaste-tenperatura egokiak gehigarrien atxikimendua hobe dezake (sakabanatzaileak esaterako) eramaileari eta pigmentuei, nahasketa uniformea ​​sustatzea. Pigmentu-eduki handiko masterbatcherako (esaterako 50% goian), aurrenahaste-denbora behar bezala luzatu daiteke, eta sakabanatzaile kopuru txiki bat gehi daiteke lehenik pigmentuen barreiagarritasuna hobetzeko. Aurrenahasketa ondoren, nahasketak kolore uniformea ​​izan behar du, pigmentu-aglomeratu eta partikula gehigarri nabaririk gabe.

2.2.3 Elikadura eta Garraioa

The premixed mixture is sent to the feeding hopper of the twin-screw extruder through a screw feeder or a belt feeder. 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.

The feeding hopper is also equipped with a drying device (such as an electric heating jacket) to prevent the raw materials from absorbing moisture again during feeding. For masterbatch with high pigment content and poor fluidity, a forced feeding device can be selected to ensure the smooth feeding of materials. Horrez gain, the feeding port of the extruder should be smooth, without dead corners, to avoid material sticking and accumulation.

2.2.4 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 5-12MPa).

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 pigments, make the pigments uniformly dispersed in the melted carrier, and promote the fusion and compatibility between the pigment, carrier and additives. 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) to make the carrier gradually melt and plasticize.

Estrusorearen barrika normalean banatzen da 4-6 tenperatura kontrolatzeko atalak (elikadura atala, urtze-atala, nahasketa atala, homogeneizatzeko atala, die buru atala), and the temperature of each section is precisely controlled according to the type of masterbatch (eramaile mota, pigment type). Adibidez, when processing PE masterbatch, the temperature of the feeding section is 100-120℃, the melting section is 160-180℃, nahasketa sekzioa 170-190 ℃ da, homogeneizatzeko sekzioa 160-180 ℃ da, eta trokelaren buruaren sekzioa 150-170 ℃ da. Tenperaturaren kontrol zehatzak garraiolaria guztiz urtzen dela berma dezake deskonposizio termikorik gabe, eta pigmentuak ez dira deskonposatzen edo koloreztatuta.

Torloju biko estrusorearen torlojuak diseinu modularra hartzen du, torloju-elementu desberdinak askatasunez konbina ditzakeena (hala nola, elementu garraiatzaileak, elementuak nahastea, zizaila-elementuak) masterbatch motaren arabera. Adibidez, pigmentu-eduki handiko eta aglomerazio erraza duen masterbatch-a prozesatzen denean, nahasketa-elementu eta zizaila-elementu gehiago konfigura daitezke nahasketa eta sakabanaketa efektua hobetzeko; jariakortasun onarekin masterbatch-a prozesatzen denean, garraiatzeko elementu gehiago konfigura daitezke ekoizpenaren eraginkortasuna hobetzeko.

2.2.5 Estrusioa eta Konformazioa

Guztiz urtua, nahastutako eta sakabanatutako materiala estrusorearen trokelaren burura bultzatzen da torlojuen bidez. The die head of the masterbatch extruder is usually equipped with multiple circular die holes (the number and size of die holes are determined according to the particle size of the masterbatch). The material is extruded from the die head at a high speed to form continuous strip-shaped semi-finished products (the diameter of the strip is usually 2-5mm, which can be adjusted according to customer needs).

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 strip. The extrusion speed is controlled according to the type of masterbatch and the particle size requirement, generally ranging from 1-3m/min. The extrusion pressure should be kept stable (fluctuation within ±0.5MPa), which can ensure the uniform diameter of the strip and the consistency of the masterbatch quality.

2.2.6 Cooling and Solidification

The extruded strip-shaped semi-finished products are sent to a cooling device for rapid cooling and solidification. The cooling method for masterbatch is usually water tank cooling, and the cooling water temperature is controlled at 20-30℃. The length of the cooling water tank is 3-5 meters, and the cooling time is 2-4 minutuak. Rapid cooling can make the strip solidify quickly, maintain the shape and size of the strip, and avoid deformation and adhesion.

It should be noted that the cooling speed should be uniform. If the cooling speed is too fast, the internal stress of the strip will be too large, and the strip will be brittle and easy to break during granulation; if the cooling speed is too slow, the strip will be soft and easy to adhere, affecting the granulation effect. After cooling, the surface of the strip should be dry, smooth and free of bubbles and cracks.

2.2.7 Cutting and Granulation

After cooling and solidification, the strip is sent to a granulator for cutting to form granular masterbatch products. The granulator is equipped with a rotary knife and a fixed knife, and the cutting speed is adjustable (generally 500-1000 rpm). The particle size of the masterbatch is controlled by adjusting the cutting speed and the speed of the strip conveying. The common particle size of masterbatch is 2-5mm (length and diameter are basically the same), which is convenient for mixing with plastic raw materials during later use.

Granulatzaileak bahetzeko gailu batez hornitu behar du kualifikaziorik gabeko partikulak kentzeko (handiegiak esaterako, txikiegia, aglomeratutako edo hautsitako partikulak). Partikula kualifikatuak hurrengo prozesuan sartzen dira, eta sailkatu gabeko partikulak birrindu eta birziklatzen dira (lehortu eta aurretik nahastu ondoren, berriro estruitu eta pikortu egiten dira).

2.2.8 Emanaldia, Ikuskapena eta ontziratzea

Masterbatch granulatua bibrazio pantaila batera bidaltzen da bahetzeko, kualifikaziorik gabeko partikulak eta ezpurutasunak gehiago kentzeko.. Pantaila dardara geruza anitzeko pantailaz hornituta dago (sare-tamaina desberdinak), bezeroen beharren arabera zehaztapen desberdinetako masterbatch partikulak kanporatu ditzakeena.

Emanaldiaren ostean, masterbatch-ak kalitate-ikuskapena egin behar du. Ikuskapen-elementuak batez ere barne hartzen ditu: kolorea (uniformetasuna, lagin estandarrarekiko koherentzia), dispersibility (mikroskopio edo proben kolorez ikusten da), kontzentrazioa (tindatze-indarraren proba), hezetasun edukia, partikulen tamainaren banaketa, etab. Kalitate estandarrak betetzen dituen masterbatch bakarra ontziratu daiteke.

Masterbatch-en ontziek ontzi itxiak eta hezetasunik gabekoak hartzen dituzte (hala nola, plastikozko ehundutako poltsak barneko plastikozko filmarekin, aluminiozko paperezko poltsak), eta ontziaren pisua 25 kg/poltsa edo 50kg/poltsa izan ohi da. Enbalatzeko poltsa produktuaren izenarekin markatuta dago, eredua, kolorea, kontzentrazioa, eramaile mota, ekoizpen data, iraupena, fabrikatzailea eta bestelako informazioa. Paketatutako masterbatch-a lehor batean gorde behar da, biltegi freskoa eta aireztatua, zuzeneko eguzki-argia eta hezetasuna saihestuz, eta iraupena da, oro har 6-12 hilabeteak.

2.3 Masterbatch Twin-Screw estrusio-efektuari eragiten dioten faktore nagusiak

Torloju bikoitzeko estrusioaren efektuak zuzenean eragiten du masterbatch-aren kalitatean (dispersibility, tinting strength, egonkortasuna). Estrusio efektuari eragiten dioten faktore asko daude, mainly including raw material characteristics, formula ratio, premixing effect, extrusion parameters and equipment performance. 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. For pigments, the particle size should be uniform and fine (20-40 sare), and the agglomeration degree should be low; organic pigments have poor heat resistance, so the extrusion temperature should be strictly controlled; inorganic pigments have high hardness, so the extruder should have good wear resistance. For carriers, the melting point and processing temperature should be consistent with the target plastic raw materials, and the compatibility with pigments should be good. For additives, the type and dosage should be reasonable, and the compatibility with carriers and pigments should be good.

Horrez gain, the moisture content of raw materials must be strictly controlled below 0.1%; if the moisture content is too high, it will cause bubbles and agglomeration in the masterbatch. Lehengaien garbitasuna ere oso garrantzitsua da; impurities in raw materials will not only affect the product quality, baina baita estrusorearen torlojua eta kanoia ere higadura.

2.3.2 Formula ratioa

The formula ratio of masterbatch (the ratio of pigment, carrier and additive) is the key to determining the quality of the product. The pigment content should be determined according to the coloring requirements and the type of pigment: high-concentration masterbatch (pigment content 50%-80%) can reduce the addition amount and production cost, but requires better dispersibility; low-concentration masterbatch (pigment content 10%-30%) has better dispersibility, but the addition amount is large and the production cost is high.

The dosage of dispersants is generally 1%-5% of the pigment dosage; too little dispersant will lead to poor dispersibility of pigments, and too much dispersant will affect the mechanical properties of the masterbatch and the colored products. The dosage of other additives (bateragarriak, heat stabilizers, lubrifikatzaileak) is generally 0.5%-3%, which should be adjusted according to the type of masterbatch and processing requirements. The formula ratio should be strictly controlled, and the error should be within ±1%, to ensure the consistency of product quality between batches.

2.3.3 Premixing Effect

Premixing is the foundation of extrusion processing. The uniformity of premixing directly affects the mixing and dispersing effect of pigments during extrusion. If the premixing is uneven, pigmentuak ezin dira eramailearen gainazalean uniformeki itsatsi, pigmentuen tokiko aglomerazioa eraginez, estrusioan materialen nahasketa irregularra, eta produktuaren sakabanagarritasuna murriztu.

Aurrenahasketa efektua ziurtatzeko, nahaste-abiadura kontrolatu behar da (800-1200 rpm), mixing time (5-10 minutuak) eta nahaste-tenperatura (40-60℃). Pigmentu-eduki handiko masterbatcherako, aurrenahaste-denbora behar bezala luzatu daiteke, eta sakabanatua gehitu daiteke lehenik eta pigmentuarekin nahastu, gero eramailearekin eta beste gehigarri batzuekin nahastu. Horrez gain, aurrez nahastutako nahasketa ikuskatu behar da; pigmentu-aglomeratu agerikoak badira, birrindu eta birnahastu behar da.

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: Masterbatch prozesatzeko torloju biko estrusoreen torlojuaren abiadura, oro har, bitartekoa da 200 to 800 rpm. Zenbat eta handiagoa izan torlojuaren abiadura, zenbat eta handiagoa izan materialek jasotzen duten ebakidura-indarra eta marruskadura-indarra, orduan eta hobea izango da pigmentuen nahasketa eta sakabanaketa efektua, eta ekoizpen-eraginkortasun handiagoa. Hala ere, torlojuaren abiadura handiegia bada, estrusio-barrunbean materialen egonaldi-denbora laburregia da, eramailearen erabateko urtzea eraginez, materialak nahikoa nahastea, eta sakabanagarritasun irregularra; torlojuaren abiadura baxuegia bada, ebakidura-indarra eta marruskadura-indarra nahikoak dira, pigmentu-aglomeratuak ezin dira guztiz hautsi, eta ekoizpen-eraginkortasuna baxua da.
• The screw speed should be adjusted according to the type of masterbatch: for masterbatch with high pigment content and easy agglomeration (such as black masterbatch, white masterbatch), a higher screw speed (500-800 rpm) is needed to ensure the uniform dispersion of pigments; for masterbatch with organic pigments (poor heat resistance), a moderate screw speed (300-500 rpm) is needed to avoid overheating and pigment decomposition.
• Estrusio-tenperatura: The extrusion temperature is the key to ensuring the melting of the carrier and the stability of the pigment. The temperature of each section of the barrel and die head must be precisely controlled according to the type of masterbatch (eramaile mota, pigment type). 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, which is mainly to promote the melting and plasticization of the carrier; nahaste-atalaren tenperatura altuagoa da, hau da, batez ere, zizaila eta nahasketa efektua hobetzeko, and promote the uniform dispersion of pigments; 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 strip.
• The temperature control precision should reach ±1℃. Adibidez, when processing PP masterbatch with organic pigments, the temperature of each section is: feeding section 110-130℃, melting section 170-190℃, mixing section 180-200℃, homogenizing section 170-190℃, die head section 160-180℃. If the temperature is too high, the pigment will decompose and the carrier will degrade; if the temperature is too low, the carrier will not be fully melted, and the pigment cannot be uniformly dispersed.
• Estrusio-presioa: The extrusion pressure of masterbatch twin-screw extrusion generally ranges from 5 to 12MPa. 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, eta dentsoagoa zerrenda. Hala ere, presioa altuegia bada, ekipoen energia-kontsumoa eta higadura handituko ditu, eta baita trokel burua blokeatzea ere; presioa baxuegia bada, materialak ezin dira guztiz konprimitu eta nahastu, tira solte dago, eta sakabanagarritasuna eskasa da.
• Estrusio-presioa masterbatch motaren eta trokelaren buruaren tamainaren arabera egokitu behar da: pigmentu eduki handia eta jariakortasun eskasa duen masterbatcherako, estrusio-presio handiagoa behar da; jariakortasun oneko masterbatcherako, nahikoa da estrusio-presio moderatua. The extrusion pressure should be kept stable, eta gorabehera ± 0,5 MPa barruan egon behar du, zerrendaren diametro uniformea ​​eta masterbatch-aren kalitatearen koherentzia bermatzeko.

2.3.5 Ekipoen Errendimendua

Torloju bikoitzeko estrusorearen errendimenduak zuzenean zehazten du estrusio-efektua.
