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, perfformiad sefydlog, environmental protection and energy saving, which has gradually replaced the traditional coloring method and become the mainstream coloring solution in the plastics industry.

In recent years, driven by the rapid development of downstream industries such as packaging, modurol, textiles, electroneg, construction and home appliances, the global masterbatch market has shown a steady and rapid growth trend. According to relevant industry data, the global masterbatch market size has exceeded 30 billion US dollars, and it is expected to maintain a compound annual growth rate of 6%-8% in the next five years. Yn eu plith, Asia-Pacific is the world’s largest masterbatch production and consumption market, yn cyfrif am fwy na 60% of the global market share, mainly due to the rapid development of the plastics industry in China, India and other countries, gwelliant parhaus o gapasiti ategol diwydiannol, a'r galw cynyddol am ansawdd uchel, cynhyrchion masterbatch swyddogaethol ac ecogyfeillgar.

Tsieina, fel cynhyrchydd a defnyddiwr swp mwyaf y byd, mae galw mawr yn y farchnad a chadwyn ddiwydiannol gyflawn. Mae allbwn blynyddol a defnydd o masterbatch yn tyfu ar gyfradd dau ddigid, yn enwedig ym meysydd cerbydau ynni newydd, pecynnu gwyrdd, tecstilau a dyfeisiau meddygol pen uchel, y galw am masterbatch perfformiad uchel (megis masterbatch gwrthsefyll tymheredd uchel, masterbatch flame-retardant, masterbatch diogelu'r amgylchedd) yn dangos tuedd twf ffrwydrol. Gyda gwelliant parhaus polisïau diogelu'r amgylchedd byd-eang (megis y gwaharddiad ar pigmentau gwenwynig a niweidiol) and the upgrading of consumer demand for high-quality plastic products, the masterbatch industry is gradually developing towards high concentration, high dispersibility, functionalization, environmental protection and intelligence.

The main development trends of the masterbatch industry are reflected in four aspects: first, environmental protection and low toxicity. With the strengthening of environmental protection awareness and the strictness of environmental protection policies, non-toxic, harmless, low-volatile and degradable environmental protection masterbatch will become the mainstream of the market, and toxic and harmful pigments (such as heavy metal pigments) will be gradually eliminated; second, functionalization. In addition to coloring, masterbatch is also developing towards functional integration, such as flame-retardant masterbatch, antistatic masterbatch, antibacterial masterbatch, UV-resistant 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, Mae allwthwyr twin-screw yn chwarae rhan hanfodol yn natblygiad y diwydiant masterbatch. Mae gan gymysgu masterbatch ofynion llym ar yr effaith cymysgu a gwasgaru, rheoli tymheredd ac effeithlonrwydd cynhyrchu allwthwyr. Cyfres lawn o allwthwyr Zhuoyue (HTS SYLFAENOL/PLUS/SUPER, ZTE, HTE) wedi'u cynllunio'n arbennig ar gyfer prosesu masterbatch, gyda manteision perfformiad wedi'u targedu, a all ddiwallu anghenion prosesu gwahanol fathau o masterbatch yn effeithiol a helpu gweithgynhyrchwyr i wella ansawdd cynnyrch ac effeithlonrwydd cynhyrchu.

1.2 Cyfansoddiad Craidd ac Egwyddor Weithio Masterbatch

Mae Masterbatch yn cynnwys tair elfen sylfaenol: pigmentau neu liwiau, cludwyr ac ychwanegion. Mae cyfrannedd a pherfformiad pob elfen yn pennu effaith ansawdd a defnydd masterbatch yn uniongyrchol. Deall cyfansoddiad craidd ac egwyddor weithredol masterbatch yw'r sail ar gyfer meistroli ei dechnoleg prosesu a dewis offer allwthio priodol.

1.2.1 Pigmentau neu Llifau: Y Gydran Lliwio Graidd

Pigmentau neu liwiau yw'r cydrannau craidd sy'n rhoi perfformiad lliwio masterbatch, cyfrif am 10%-80% o gyfansoddiad y masterbatch (mae'r gyfran benodol yn dibynnu ar y math o pigment, gofynion lliwio a chrynodiad masterbatch). Rhennir pigmentau yn pigmentau organig a phigmentau anorganig: mae gan pigmentau organig liwiau llachar, cryfder lliwio uchel, tryloywder da, ond ymwrthedd gwres gwael a gwrthsefyll tywydd, a ddefnyddir yn bennaf mewn plastigau prosesu tymheredd isel (megis addysg gorfforol, PP) a chynhyrchion â gofynion lliw uchel (megis tecstilau, ffilmiau pecynnu); mae gan pigmentau anorganig ymwrthedd gwres da, weather resistance and chemical stability, but low tinting strength and poor transparency, mainly used in high-temperature processing plastics (such as engineering plastics) and outdoor products (such as building materials, automotive exterior parts).

Dyes are different from pigments. Dyes have good solubility in plastic raw materials, bright colors and high transparency, but poor heat resistance and light resistance, mainly used in transparent plastic products (such as PET bottles, PC sheets). The selection of pigments or dyes should be based on the type of plastic raw materials (tymheredd prosesu), product use environment (indoor/outdoor), coloring requirements (color brightness, tryloywder) and environmental protection requirements, to ensure that the masterbatch has stable coloring performance and meets the use requirements of downstream products.

1.2.2 Carriers: The Dispersion and Adhesion Component

Carriers are the matrix of masterbatch, cyfrif am 10%-80% o gyfansoddiad y masterbatch, mainly playing the role of dispersing pigments/dyes and adhering to plastic raw materials. The carrier must have good compatibility with both pigments/dyes and the target plastic raw materials (the plastic raw materials to be colored), otherwise it will affect the dispersibility of pigments and the coloring effect of products. Common carrier materials include polyethylene (Addysg Gorfforol), polypropylen (PP), polyvinyl clorid (PVC), polyamid (PA), polyethylene terephthalate (PET), etc., which are selected according to the type of target plastic raw materials: for example, PE carrier is used for PE plastic coloring, PP carrier is used for PP plastic coloring, and PA carrier is used for engineering plastic PA coloring.

The carrier should also have good processing fluidity, sy'n ffafriol i wasgariad unffurf pigmentau yn ystod prosesu allwthio a chymysgu masterbatch gyda deunyddiau crai plastig targed. Yn ogystal, dylai pwynt toddi a thymheredd prosesu'r cludwr fod yn gyson â neu ychydig yn is na'r deunyddiau crai plastig targed, er mwyn osgoi dadelfennu'r cludwr neu'r plastig targed wrth brosesu.

1.2.3 Ychwanegion: Y Gydran Swyddogaethol Ategol

Mae ychwanegion yn gydrannau ategol a ychwanegir i wella'r perfformiad prosesu, dispersibility a defnydd perfformiad o masterbatch, cyfrif am 1%-10% o gyfansoddiad y masterbatch. Mae math a dos yr ychwanegion yn cael eu pennu yn ôl y math o masterbatch a gofynion prosesu. Mae ychwanegion cyffredin yn cynnwys:

• Gwasgarwyr: Yr ychwanegyn pwysicaf yn masterbatch, a all leihau tensiwn wyneb pigmentau, prevent pigment agglomeration, and make pigments uniformly dispersed in the carrier. Common dispersants include polyethylene wax, polypropylene wax, stearic acid, stearad calsiwm, etc. The addition of dispersants can significantly improve the dispersibility of masterbatch, ensure uniform coloring of products, and reduce the wear of extrusion equipment.
• Compatibilizers: Used to improve the compatibility between pigments and carriers, and between masterbatch and target plastic raw materials. Er enghraifft, when the carrier and target plastic have poor compatibility (such as PE carrier and PA plastic), compatibilizers (such as maleic anhydride grafted polyethylene) can be added to enhance the bonding force between them, avoid the separation of masterbatch and target plastic during processing, and improve the mechanical properties of products.
• Heat Stabilizers: 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, etc., 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.
• Ireidiau: Used to reduce the friction between materials and extrusion equipment (screw, casgen, marw pen), improve processing fluidity, lleihau'r defnydd o ynni, 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, color difference and other defects in the colored products.

1.3 Common Classification of Masterbatch

Masterbatch can be divided into different types according to different classification standards, such as coloring type, carrier type, application field, functional type, etc. The correct classification helps to better understand the performance characteristics and processing requirements of masterbatch, and select appropriate extrusion equipment and processing techniques.

1.3.1 Classification by Coloring Type

According to the type of coloring component, masterbatch can be divided into color masterbatch, white masterbatch and black masterbatch.

• Lliw Masterbatch: The most common type of masterbatch, which uses organic or inorganic pigments of various colors (such as red, yellow, blue, green, orange) as coloring components, and is used for coloring plastic products of various colors. Y cryfder lliwio, disgleirdeb lliw a dispersibility masterbatch lliw yw'r dangosyddion allweddol i fesur ei ansawdd.
• Masterbatch Gwyn: Gan ddefnyddio titaniwm deuocsid (TiO2) fel y brif gydran lliwio, fe'i defnyddir ar gyfer gwynnu cynhyrchion plastig neu fel lliw sylfaen ar gyfer masterbatch lliw golau. Y gwynder, cwmpasu pŵer a dispersibility o masterbatch gwyn yw'r dangosyddion allweddol. Mae gan ditaniwm deuocsid galedwch uchel, sydd â gofynion uchel ar wrthwynebiad gwisgo offer allwthio.
• Masterbatch Du: Defnyddio carbon du fel y prif gydran lliwio, fe'i defnyddir ar gyfer lliwio du o gynhyrchion plastig. Mae gan garbon du wrthwynebiad UV da ac ymwrthedd tywydd, a gall hefyd wella priodweddau mecanyddol cynhyrchion plastig. Mae gwasgaredd carbon du yn allweddol i ansawdd y masterbatch du. Poor dispersibility will cause black spots and streaks in products.

1.3.2 Classification by Carrier Type

According to the type of carrier, masterbatch can be divided into PE masterbatch, PP masterbatch, PVC masterbatch, PA masterbatch, PET masterbatch, etc.

• PE Masterbatch: Using PE as the carrier, it is suitable for coloring PE plastic products (such as PE films, PE pipes, PE injection molding parts). It has good compatibility with PE raw materials, good processing fluidity and uniform coloring.
• PP Masterbatch: Using PP as the carrier, it is suitable for coloring PP plastic products (such as PP fibers, PP injection molding parts, PP sheets). It has good heat resistance and is suitable for high-temperature processing of PP.
• PVC Masterbatch: Using PVC as the carrier, it is suitable for coloring PVC plastic products (such as PVC pipes, Proffiliau PVC, PVC films). Mae angen ei gydweddu â sefydlogwyr gwres PVC er mwyn osgoi dadelfennu PVC wrth brosesu.
• Masterbatch Plastig Peirianneg: Defnyddio plastigau peirianneg (PA, PC, PBT, etc.) fel cludwyr, mae'n addas ar gyfer lliwio cynhyrchion plastig peirianneg (megis rhannau modurol, cydrannau trydanol). Mae ganddo wrthwynebiad gwres da a chydnawsedd â phlastigau peirianneg, ac mae ganddo ofynion uchel ar offer prosesu allwthio.

1.3.3 Dosbarthiad yn ôl Maes Cais

Yn ôl y maes cais o masterbatch, gellir ei rannu'n masterbatch ffibr, masterbatch ffilm, masterbatch mowldio chwythu, masterbatch allwthio, masterbatch mowldio chwistrellu, etc., sy'n cyfateb i'r pum maes cais mawr o masterbatch.

• Fiber Masterbatch: Defnyddir ar gyfer lliwio ffibrau cemegol (megis ffibr polyester, ffibr neilon), a ddefnyddir mewn carpedi, textiles, clustogau a chynhyrchion eraill. 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.
• Extrusion Masterbatch: Used for coloring extrusion products (such as sheets, pibellau, wires and cables), which requires good dimensional stability and uniform coloring, and no color difference on the product surface.
• Injection Molding Masterbatch: Used for coloring injection molding products (megis rhannau modurol, cynhyrchion electronig, deunyddiau adeiladu, offer cartref, dodrefn, tegannau), sy'n gofyn am wasgaredd uchel a pherfformiad sefydlog, a dim gwahaniaeth lliw rhwng sypiau o gynhyrchion.

1.3.4 Dosbarthiad yn ôl Math Swyddogaethol

Yn ôl y swyddogaethau ychwanegol o masterbatch, gellir ei rannu'n masterbatch cyffredin (swyddogaeth lliwio yn unig) a masterbatch swyddogaethol (lliwio + swyddogaethau ychwanegol). Masterbatch swyddogaethol yw tuedd datblygu'r diwydiant, ac mae mathau cyffredin yn cynnwys masterbatch flame-retardant, antistatic masterbatch, antibacterial masterbatch, UV-resistant masterbatch, masterbatch caledu, etc. Mae masterbatch swyddogaethol yn gofyn am ychwanegu ychwanegion swyddogaethol cyfatebol ar sail masterbatch cyffredin, sydd â gofynion uwch ar effaith cymysgu a gwasgaru offer allwthio.

2. Technoleg Prosesu Craidd o Masterbatch: Technoleg Allwthio Twin-Screw

Mae prosesu Masterbatch yn bennaf yn cynnwys cymysgu, allwthio, oeri, granwleiddio a phrosesau eraill, ymhlith y rhain mae technoleg allwthio dau-sgriw yn dechnoleg graidd o gymysgu a granwleiddio masterbatch. O'i gymharu â thechnoleg allwthio un-sgriw, Mae gan dechnoleg allwthio dau-sgriw fanteision gallu cymysgu a gwasgaru cryf, rheolaeth tymheredd manwl gywir, amser preswylio byr, effeithlonrwydd cynhyrchu uchel ac addasrwydd cryf i ddeunyddiau crai, a all ddatrys problemau allweddol prosesu masterbatch yn effeithiol (megis crynhoad pigment, cymysgu anwastad, effeithlonrwydd cynhyrchu isel) a sicrhau ansawdd y cynhyrchion masterbatch.

Mae cymysgu masterbatch yn un o brif gymwysiadau allwthwyr twin-screw. Mae ansawdd y masterbatch yn cael ei bennu'n uniongyrchol gan berfformiad yr allwthiwr dau-sgriw a rhesymoledd y broses brosesu. Mae gofynion allweddol prosesu masterbatch ar gyfer allwthwyr twin-screw: effaith cymysgu a gwasgaru cryf (i sicrhau gwasgariad unffurf o pigmentau), rheolaeth tymheredd manwl gywir (er mwyn osgoi dadelfennu pigment a diraddio cludwyr), grym cneifio priodol (i dorri agglomerates pigment heb niweidio gronynnau pigment), effeithlonrwydd cynhyrchu uchel (i ddiwallu anghenion cynhyrchu màs) a gwrthsefyll gwisgo da (i addasu i wisgo pigmentau caledwch uchel fel titaniwm deuocsid a charbon du).

2.1 Anawsterau Prosesu Masterbatch a Gofynion ar gyfer Offer Allwthio

Er bod technoleg allwthio twin-sgriw yn addas ar gyfer prosesu masterbatch, oherwydd hynodrwydd cyfansoddiad masterbatch (cynnwys pigment uchel, crynhoad hawdd o pigmentau) a gofynion prosesu (gwasgariad unffurf, perfformiad sefydlog), mae yna lawer o anawsterau o hyd o ran prosesu gwirioneddol. 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. Yn ogystal, 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 (megis addysg gorfforol, 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 (gan arwain at bylu lliw, afliwiad), a bydd y cludwr yn diraddio (gan arwain at lai o briodweddau mecanyddol y masterbatch). Mae hwn yn anhawster allweddol arall mewn prosesu masterbatch.

Mae hyn yn ei gwneud yn ofynnol i'r offer allwthio fod â chynhwysedd rheoli tymheredd manwl gywir ac amser preswylio byr. Dylid rhannu casgen yr allwthiwr yn adrannau rheoli tymheredd lluosog, a dylid rheoli tymheredd pob adran yn fanwl gywir o fewn yr ystod optimaidd (fel arfer 150-220 ℃ ar gyfer masterbatch cyffredin, 200-280℃ ar gyfer masterbatch plastig peirianneg), gyda manwl gywirdeb rheoli tymheredd o ± 1 ℃. Dylid optimeiddio'r strwythur sgriwiau i fyrhau amser preswylio'r deunydd yn yr allwthiwr (usually 1-3 munudau), osgoi cyswllt hirdymor rhwng y deunydd a thymheredd uchel.

2.1.3 Gwisgo'r Sgriw a'r Gasgen a Achosir gan Bigmentau Caledwch Uchel

Mae gan pigmentau anorganig fel titaniwm deuocsid a charbon du galedwch uchel (Mohs caledwch 5-7), a fydd yn achosi traul difrifol i sgriw a gasgen yr allwthiwr yn ystod prosesu allwthio. Os oes gan y sgriw a'r gasgen ymwrthedd gwisgo gwael, byddant yn cael eu gwisgo'n gyflym, gan arwain at lai o rym cneifio a chynhwysedd cymysgu'r allwthiwr, effeithio ar wasgaredd y masterbatch a lleihau bywyd gwasanaeth yr offer.

Mae hyn yn ei gwneud yn ofynnol i sgriw a gasgen yr allwthiwr gael eu gwneud o ddeunyddiau gwrthsefyll traul o ansawdd uchel a'u prosesu gan dechnoleg gweithgynhyrchu uwch. Er enghraifft, gellir gwneud y sgriw a'r gasgen o ddur aloi sy'n gwrthsefyll traul wedi'i fewnforio, a chael triniaeth gyfansawdd bimetallig neu driniaeth cladin laser, which can greatly improve the wear resistance and corrosion resistance of the screw and barrel, and adapt to the processing of masterbatch with high-hardness pigments.

2.1.4 Instability of Product Quality Between Batches

Masterbatch processing requires strict control of various parameters (such as formula ratio, mixing time, extrusion temperature, cyflymder sgriw, feeding speed). 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, cyflymder sgriw, tymheredd allwthio a pharamedrau eraill, a storio setiau lluosog o baramedrau fformiwla. Wrth gynhyrchu gwahanol sypiau o masterbatch, dim ond y paramedrau cyfatebol sydd angen eu galw, osgoi dadfygio dro ar ôl tro, sicrhau sefydlogrwydd ansawdd y cynnyrch rhwng sypiau.

2.1.5 Gofynion Uchel ar Hylifedd Prosesu

Mae gan Masterbatch gynnwys pigment uchel, a fydd yn lleihau hylifedd prosesu'r deunydd. Os yw'r hylifedd prosesu yn rhy wael, bydd y deunydd yn anodd ei gyfleu a'i allwthio, gan arwain at effeithlonrwydd cynhyrchu isel, pwysau allwthio ansefydlog a hyd yn oed rhwystr offer.

Mae hyn yn ei gwneud yn ofynnol i'r offer allwthio feddu ar allu cludo cryf a grym cneifio addasadwy. Dylai'r allwthiwr twin-screw fabwysiadu traw sgriw rhesymol, dylunio cymhareb plwm a chywasgu, and the screw should be equipped with sufficient conveying elements to ensure the smooth conveying of materials. Yn ogystal, 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, feeding, toddi, mixing and shearing, allwthio, oeri, gronynnyn, screening and packaging. The core purpose is to uniformly disperse pigments, carriers and additives to form high-quality masterbatch granules. The specific working principle and process flow are as follows:

2.2.1 Raw Material Pretreatment

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, ychwanegion (dispersants, compatibilizers, heat stabilizers, etc.). The pretreatment steps are as follows:

• Drying Treatment: Some pigments (such as organic pigments) and carriers (such as 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, and even cause hydrolytic degradation of the carrier. Felly, the raw materials must be dried before processing. The drying temperature and time are determined according to the type of raw material: for example, organic pigments are dried at 60-80℃ for 2-4 oriau, PE/PP carriers are dried at 80-100℃ for 3-5 oriau, and PA carriers are dried at 100-120℃ for 6-8 oriau. The moisture content of the dried raw materials should be controlled below 0.1%.
• Crushing and Sieving: For pigments with large particle size (such as titanium dioxide agglomerates) and carriers with uneven particle size, crushing and sieving treatment should be carried out to ensure the uniformity of raw materials. The particle size of the crushed raw materials should be controlled at 20-40 mesh, 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, stones, llwch) during production and transportation. Impurities not only affect the quality of the masterbatch, but also wear the screw and barrel of the extruder, and even cause equipment blockage. Felly, rhaid hidlo'r deunyddiau crai a'u tynnu cyn eu defnyddio, defnyddio sgrin hidlo gyda maint rhwyll priodol i gael gwared ar amhureddau.

2.2.2 Rhag-gymysgu

Premixing yw'r cam allweddol i wella effaith cymysgu a gwasgaru masterbatch. Yn ôl y gymhareb fformiwla, y sych, pigmentau wedi'u malu ac amhuredd wedi'u tynnu, cludwyr ac ychwanegion yn cael eu rhoi mewn cymysgydd cyflym ar gyfer premixing. Pwrpas premixing yw gwneud i'r pigmentau a'r ychwanegion gadw'n unffurf i wyneb y gronynnau cludo, ffurfio cymysgedd rhagarweiniol, a gosod sylfaen ar gyfer y gwasgariad unffurf yn ystod allwthio.

Prif baramedrau premixing yw cyflymder cymysgu, amser cymysgu a chymysgu tymheredd. Mae'r cyflymder cymysgu yn gyffredinol 800-1200 rpm, yr amser cymysgu yw 5-10 munudau, a rheolir y tymheredd cymysgu ar 40-60 ℃. Gall y tymheredd cymysgu priodol wella adlyniad ychwanegion (megis gwasgarwyr) i'r cludwr a pigmentau, hyrwyddo cymysgu unffurf. Ar gyfer masterbatch gyda chynnwys pigment uchel (megis 50% uchod), gellir ymestyn yr amser rhag-gymysgu yn briodol, a gellir ychwanegu ychydig bach o wasgarwr yn gyntaf i wella gwasgaredd pigmentau. Ar ôl rhag-gymysgu, dylai'r gymysgedd fod yn unffurf o ran lliw, heb agglomerates pigment amlwg a gronynnau ychwanegion.

2.2.3 Bwydo a Chludo

Anfonir y cymysgedd rhag-gymysg i hopiwr bwydo'r allwthiwr dau-sgriw trwy beiriant bwydo sgriw neu beiriant bwydo gwregys.. Mae dyfais bwydo'r allwthiwr fel arfer wedi'i gyfarparu â swyddogaeth rheoleiddio cyflymder trosi amlder, a all addasu'r cyflymder bwydo yn ôl cyflymder y sgriw a'r cyflymder allwthio i sicrhau bod y deunyddiau'n mynd i mewn i'r ceudod allwthio yn sefydlog ac yn unffurf, osgoi cronni deunydd neu fwydo annigonol.

Mae gan y hopiwr bwydo ddyfais sychu hefyd (megis siaced gwresogi trydan) i atal y deunyddiau crai rhag amsugno lleithder eto yn ystod bwydo. Ar gyfer masterbatch gyda chynnwys pigment uchel a hylifedd gwael, gellir dewis dyfais bwydo gorfodol i sicrhau bod deunyddiau'n cael eu bwydo'n llyfn. Yn ogystal, dylai porthladd bwydo'r allwthiwr fod yn llyfn, heb gorneli marw, er mwyn osgoi glynu a chronni deunydd.

2.2.4 Toddi, Cymysgu a Chneifio

Mae'r deunyddiau sy'n mynd i mewn i geudod allwthio'r allwthiwr dau-sgriw yn cael eu gwthio ymlaen yn barhaus gan y sgriwiau cylchdroi. Mae'r ceudod allwthio yn cynnwys sgriw a casgen, ac mae cyfaint y ceudod allwthio yn gostwng yn raddol ar hyd y cyfeiriad echelin. Pan fydd y sgriwiau'n cylchdroi, mae'r deunyddiau'n cael eu cywasgu'n raddol o dan weithred y sgriwiau a'r gasgen, ac mae'r pwysau yn y ceudod allwthio yn cynyddu'n raddol (yn gyffredinol 5-12MPa).

Ar yr un pryd, mae'r deunyddiau'n destun grym cneifio cryf a grym ffrithiant a gynhyrchir gan y symudiad cymharol rhwng y sgriwiau a'r gasgen, yn ogystal â rhwng y teithiau sgriw. Gall y grym cneifio a'r grym ffrithiant dorri crynoadau pigmentau yn llawn, gwnewch y pigmentau wedi'u gwasgaru'n unffurf yn y cludwr wedi'i doddi, a hyrwyddo'r ymasiad a'r cydnawsedd rhwng y pigment, cludwr ac ychwanegion. The friction force can also generate a certain amount of heat, which is combined with the external heating of the barrel (electric heating or steam heating) to make the carrier 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, die head section), and the temperature of each section is precisely controlled according to the type of masterbatch (carrier type, pigment type). Er enghraifft, when processing PE masterbatch, the temperature of the feeding section is 100-120℃, the melting section is 160-180℃, the mixing section is 170-190℃, the homogenizing section is 160-180℃, and the die head section is 150-170℃. Gall yr union reolaeth tymheredd sicrhau bod y cludwr wedi'i doddi'n llawn heb ddadelfennu thermol, ac nid yw'r pigmentau wedi'u dadelfennu na'u lliwio.

Mae sgriw yr allwthiwr twin-screw yn mabwysiadu dyluniad modiwlaidd, a all gyfuno gwahanol elfennau sgriw yn rhydd (megis cyfleu elfennau, cymysgu elfennau, elfennau cneifio) yn ôl y math o masterbatch. Er enghraifft, wrth brosesu masterbatch gyda chynnwys pigment uchel a chrynhoad hawdd, gellir ffurfweddu mwy o elfennau cymysgu ac elfennau cneifio i wella'r effaith cymysgu a gwasgaru; wrth brosesu masterbatch gyda hylifedd da, gellir ffurfweddu mwy o elfennau cludo i wella effeithlonrwydd cynhyrchu.

2.2.5 Allwthio a Siapio

Mae'r toddi yn llawn, mae deunydd cymysg a gwasgaredig yn cael ei wthio i ben marw'r allwthiwr gan y sgriwiau. Mae pen marw yr allwthiwr masterbatch fel arfer wedi'i gyfarparu â thyllau marw crwn lluosog (pennir nifer a maint y tyllau marw yn ôl maint gronynnau'r masterbatch). Mae'r deunydd yn cael ei allwthio o'r pen marw ar gyflymder uchel i ffurfio cynhyrchion lled-orffen siâp stribed parhaus (mae diamedr y stribed fel arfer yn 2-5mm, y gellir ei addasu yn unol ag anghenion cwsmeriaid).

Mae tymheredd y pen marw ychydig yn is na thymheredd yr adran homogeneiddio, a all atal y deunydd rhag dadelfennu oherwydd tymheredd gormodol a sicrhau effaith siapio'r stribed. Rheolir y cyflymder allwthio yn ôl y math o masterbatch a'r gofyniad maint gronynnau, yn gyffredinol yn amrywio o 1-3m/munud. Dylid cadw'r pwysau allwthio yn sefydlog (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 munudau. 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, a bydd y stribed yn frau ac yn hawdd ei dorri yn ystod gronynnu; os yw'r cyflymder oeri yn rhy araf, bydd y stribed yn feddal ac yn hawdd ei gadw, effeithio ar yr effaith gronynnu. Ar ôl oeri, dylai wyneb y stribed fod yn sych, llyfn ac yn rhydd o swigod a chraciau.

2.2.7 Torri a Granulation

Ar ôl oeri a solidification, anfonir y stribed i granulator i'w dorri i ffurfio cynhyrchion masterbatch gronynnog. Mae'r granulator wedi'i gyfarparu â chyllell cylchdro a chyllell sefydlog, ac mae'r cyflymder torri yn addasadwy (yn gyffredinol 500-1000 rpm). Rheolir maint gronynnau'r masterbatch trwy addasu'r cyflymder torri a chyflymder cludo'r stribed. Maint gronynnau cyffredin masterbatch yw 2-5mm (hyd a diamedr yn y bôn yr un fath), which is convenient for mixing with plastic raw materials during later use.

The granulator should be equipped with a screening device to remove unqualified particles (such as too large, too small, agglomerated or broken particles). The qualified particles enter the next process, and the unqualified particles are crushed and recycled (after drying and premixing, they are re-extruded and granulated).

2.2.8 Screening, Inspection and Packaging

The granulated masterbatch is sent to a vibrating screen for screening to further remove unqualified particles and impurities. The vibrating screen is equipped with a multi-layer screen (different mesh sizes), which can screen out masterbatch particles of different specifications according to customer needs.

After screening, the masterbatch needs to undergo quality inspection. The inspection items mainly include: lliw (unffurfiaeth, cysondeb â'r sampl safonol), dispersibility (arsylwi gan ficrosgop neu liwio darn prawf), canolbwyntio (prawf cryfder lliwio), cynnwys lleithder, dosbarthiad maint gronynnau, etc. Dim ond y masterbatch sy'n bodloni'r safonau ansawdd y gellir ei becynnu.

Mae pecynnu masterbatch yn mabwysiadu pecynnu wedi'i selio sy'n atal lleithder (megis bagiau gwehyddu plastig gyda ffilm plastig mewnol, bagiau ffoil alwminiwm), ac mae'r pwysau pecynnu fel arfer yn 25kg / bag neu 50kg / bag. Mae'r bag pecynnu wedi'i farcio ag enw'r cynnyrch, model, lliw, canolbwyntio, carrier type, dyddiad cynhyrchu, oes silff, gwneuthurwr a gwybodaeth arall. Dylai'r masterbatch wedi'i becynnu gael ei storio mewn sych, warws oer ac wedi'i awyru, osgoi golau haul uniongyrchol a lleithder, ac mae'r oes silff yn gyffredinol 6-12 misoedd.

2.3 Ffactorau Allweddol Sy'n Effeithio ar Effaith Allwthio Twin-Sgriw Masterbatch

The effect of twin-screw extrusion directly affects the quality of masterbatch (dispersibility, tinting strength, stability). There are many factors affecting the extrusion effect, 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, maint gronynnau, 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 mesh), 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, felly dylai fod gan yr allwthiwr ymwrthedd gwisgo da. Ar gyfer cludwyr, dylai'r pwynt toddi a'r tymheredd prosesu fod yn gyson â'r deunyddiau crai plastig targed, a dylai'r cydnawsedd â pigmentau fod yn dda. Ar gyfer ychwanegion, dylai'r math a'r dos fod yn rhesymol, a dylai'r cydnawsedd â chludwyr a pigmentau fod yn dda.

Yn ogystal, rhaid rheoli cynnwys lleithder deunyddiau crai yn llym isod 0.1%; os yw'r cynnwys lleithder yn rhy uchel, bydd yn achosi swigod a chrynhoad yn y masterbatch. Mae purdeb deunyddiau crai hefyd yn bwysig iawn; bydd amhureddau mewn deunyddiau crai nid yn unig yn effeithio ar ansawdd y cynnyrch, but also wear the screw and barrel of the extruder.

2.3.2 Cymhareb Fformiwla

Cymhareb fformiwla masterbatch (cymhareb y pigment, cludwr ac ychwanegyn) yw'r allwedd i bennu ansawdd y cynnyrch. 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 (compatibilizers, heat stabilizers, ireidiau) 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, the pigments cannot be uniformly adhered to the surface of the carrier, resulting in local agglomeration of pigments, uneven mixing of materials during extrusion, and reduced product dispersibility.

To ensure the premixing effect, it is necessary to control the mixing speed (800-1200 rpm), mixing time (5-10 munudau) and mixing temperature (40-60℃). Ar gyfer masterbatch gyda chynnwys pigment uchel, gellir ymestyn yr amser rhag-gymysgu yn briodol, and the dispersant can be added first and mixed with the pigment, then mixed with the carrier and other additives. Yn ogystal, the premixed mixture should be inspected; if there are obvious pigment agglomerates, it should be crushed and remixed.

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.

• Cyflymder Sgriw: The screw speed of twin-screw extruders for masterbatch processing generally ranges from 200 i 800 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 pigments, and the higher the production efficiency. Fodd bynnag, 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 carrier, insufficient mixing of materials, and uneven dispersibility; if the screw speed is too low, the shear force and friction force are insufficient, the pigment agglomerates cannot be fully broken, ac mae'r effeithlonrwydd cynhyrchu yn isel.
• Dylid addasu cyflymder y sgriw yn ôl y math o masterbatch: ar gyfer masterbatch gyda chynnwys pigment uchel a chrynhoad hawdd (megis masterbatch du, masterbatch gwyn), cyflymder sgriw uwch (500-800 rpm) sydd ei angen i sicrhau gwasgariad unffurf pigmentau; ar gyfer masterbatch gyda pigmentau organig (ymwrthedd gwres gwael), cyflymder sgriw cymedrol (300-500 rpm) sydd ei angen i osgoi gorboethi a dadelfennu pigment.
• Tymheredd Allwthio: Y tymheredd allwthio yw'r allwedd i sicrhau toddi'r cludwr a sefydlogrwydd y pigment. Rhaid rheoli tymheredd pob rhan o'r gasgen a'r pen marw yn union yn ôl y math o masterbatch (carrier type, pigment type). Mae tymheredd yr adran fwydo yn is (ychydig yn uwch na thymheredd sychu'r deunyddiau crai), which is mainly to prevent the materials from caking and ensure smooth feeding; the temperature of the melting section is medium, which is mainly to promote the melting and plasticization of the carrier; the temperature of the mixing section is higher, which is mainly to enhance the shear and mixing effect, and promote the uniform dispersion of pigments; the temperature of the homogenizing section is slightly lower than the mixing section, which is mainly to ensure the uniform temperature and viscosity of the materials, and avoid thermal decomposition; the temperature of the die head section is slightly lower than the homogenizing section, which is to ensure the shaping effect of the strip.
• The temperature control precision should reach ±1℃. Er enghraifft, 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.
• Extrusion Pressure: 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, and the denser the strip. Fodd bynnag, 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 strip is loose, and the dispersibility is poor.
• The extrusion pressure should be adjusted according to the type of masterbatch and the die head size: for masterbatch with high pigment content and poor fluidity, a higher extrusion pressure is needed; for masterbatch with good fluidity, a moderate extrusion pressure is sufficient. Dylid cadw'r pwysau allwthio yn sefydlog, and the fluctuation should be within ±0.5MPa, to ensure the uniform diameter of the strip and the consistency of the masterbatch quality.

2.3.5 Equipment Performance

The performance of the twin-screw extruder directly determines the extrusion effect. The key performance indicators of the extruder include mixing and dispersing capacity, temperature control precision, ymwrthedd gwisgo, conveying capacity and intelligent control capacity.

Mae gan bob cyfres ei nodweddion perfformiad ei hun a senarios addasu wedi'u targedu, a all ddarparu atebion prosesu personol ac effeithlon ar gyfer gweithgynhyrchwyr masterbatch o wahanol raddfeydd.

3.1 Manteision Craidd Allwthwyr Zhuoyue ar gyfer Prosesu Masterbatch

P'un a yw'n gyfres HTS SUPER uchel neu'r gyfres ZTE cost-effeithiol, mae gan holl allwthwyr Zhuoyue y manteision craidd canlynol, sydd wedi'u optimeiddio'n arbennig ar gyfer prosesu masterbatch, sicrhau ansawdd uchel, cynhyrchu effeithlon a sefydlog:

3.1.1 Effaith Cymysgu a Gwasgaru Ardderchog

Y gofyniad craidd o brosesu masterbatch yw gwasgariad unffurf pigmentau. All Zhuoyue’s twin-screw extruders adopt an intermeshing co-rotating structure, with a reasonable screw pitch, dylunio cymhareb plwm a chywasgu. The intermeshing and rotating of the twin screws can generate strong shear force and kneading force, which can fully break the agglomerates of pigments (even small agglomerates of 100μm above), and make the pigments uniformly dispersed in the carrier. The mixing uniformity of the extruders can reach more than 95%, which is much higher than that of ordinary twin-screw extruders (85%-90%).

Yn ogystal, the screws of all series of extruders adopt a modular design, which can freely combine different types of screw elements (cyfleu elfennau, cymysgu elfennau, elfennau cneifio) yn ôl y math o masterbatch (such as color masterbatch, masterbatch gwyn, black masterbatch) and pigment characteristics. Er enghraifft, when processing black masterbatch with carbon black (easy agglomeration), gellir ffurfweddu mwy o elfennau cymysgu ac elfennau cneifio i wella'r effaith cymysgu a gwasgaru; when processing color masterbatch with organic pigments (ymwrthedd gwres gwael), more conveying elements and fewer shearing elements can be configured to shorten the residence time and avoid pigment decomposition.

3.1.2 Rheoli Tymheredd Cywir, Avoiding Pigment Decomposition

Masterbatch processing has strict requirements on temperature control, and the temperature fluctuation must be controlled within ±1℃ to avoid pigment decomposition and carrier degradation. All Zhuoyue’s extruders adopt an advanced intelligent temperature control system, which is composed of high-precision temperature sensors, heating elements and cooling elements. The barrel is divided into 4-6 independent temperature control sections, and the temperature of each section can be precisely adjusted and controlled in real time.

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 automatically adjust the heating power or start the cooling system to return the temperature to the set range. Yn ogystal, the barrel of the extruder 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 strip.
