1. Iwwersiicht iwwer Masterbatch Industrie a Core Knowledge

1.1 Aktuell Situatioun an Entwécklung Trend vun Masterbatch Industrie

Masterbatch, och bekannt als Faarfmasterbatch oder Faarfkonzentrat, ass eng nei Aart vu Plastiksfaarwmaterial mat héijer Konzentratioun, héich Dispersibilitéit a praktesch Benotzung. Et gëtt gemaach duerch eenheetlech Verdeelung vu Pigmenter oder Faarfstoffer, Träger an Zousatzstoffer an engem spezifesche Verhältnis duerch professionell Mëschung an Extrusiounsgranulatiounstechnologie. Am Verglach mat der traditioneller direkter Faarfmethod (direkt Pigmenter zu Plastiks Matière première), Masterbatch huet d'Virdeeler vum praktesche Gebrauch, eenheetlech Faarf, stabil Leeschtung, Ëmweltschutz an Energiespueren, déi no an no déi traditionell Faarfmethod ersat huet an d'Mainstream Faarfléisung an der Plastikindustrie ginn ass.

An de leschte Joren, gedriwwe vun der rapider Entwécklung vun downstream Industrien wéi Verpakung, automobile, Textilien, elektronesch, Bau an doheem Apparater, de globale Masterbatch Maart huet e stännegen a séiere Wuesstumstrend gewisen. No relevant Industrie Daten, déi global Masterbatch Maart Gréisst huet iwwerschratt 30 Milliarden US Dollar, an et gëtt erwaart eng zesummegesat alljährlechen Wuesstem Taux vun erhalen 6%-8% an den nächste fënnef Joer. Ënnert hinnen, Asien-Pazifik ass de weltgréisste Masterbatch Produktioun a Konsummaart, Rechnung fir méi wéi 60% vum weltwäite Maartundeel, haaptsächlech wéinst der rapider Entwécklung vun der Plastikindustrie a China, Indien an aner Länner, déi kontinuéierlech Verbesserung vun der industrieller Ënnerstëtzungskapazitéit, an déi ëmmer méi Nofro fir héich Qualitéit, funktionell an ëmweltfrëndlech Masterbatch Produiten.

China, als weltgréisste Masterbatch Produzent a Konsument, huet eng enorm Maartfuerderung an eng komplett industriell Kette. Den alljährlechen Output an de Konsum vu Masterbatch wuessen mat engem duebelzifferen Taux, besonnesch an de Beräicher vun neien Energie Gefierer, gréng Verpakung, héich-Enn Textilien a medezinesch Apparater, der Nofro fir héich-Performance Masterbatch (wéi héich-Temperatur resistent géint Masterbatch, Flam-retardant Masterbatch, Ëmweltschutz Masterbatch) weist en explosive Wuesstumstrend. Mat der kontinuéierlecher Verbesserung vun der globaler Ëmweltschutzpolitik (wéi zum Beispill de Verbuet vu gëftege a schiedleche Pigmenter) an d'Upgrade vun der Konsumentefuerderung fir qualitativ héichwäerteg Plastikprodukter, d'Masterbatch Industrie entwéckelt sech lues a lues a Richtung héich Konzentratioun, héich Dispersibilitéit, Funktionaliséierung, Ëmweltschutz an Intelligenz.

D'Haaptentwécklungstrends vun der Masterbatch Industrie sinn a véier Aspekter reflektéiert: éischten, Ëmweltschutz a geréng Toxizitéit. Mat der Stäerkung vum Ëmweltschutzbewosstsinn an der Striktitéit vun der Ëmweltschutzpolitik, net gëfteg, harmlos, niddereg liichtflüchtege an ofbaubar Ëmweltschutz Masterbatch wäert de Mainstream vum Maart ginn, a gëfteg a schiedlech Pigmenter (wéi Schwéiermetallpigmenter) wäert lues a lues eliminéiert ginn; zweeten, Funktionaliséierung. Zousätzlech zu Faarwen, Masterbatch entwéckelt sech och Richtung funktionell Integratioun, wéi Flam-retardant Masterbatch, antistatesch Masterbatch, antibakteriell Masterbatch, UV-resistente Masterbatch, déi de spezielle Gebrauchsufuerderunge vun Downstream Produkter erfëllen kënnen; drëtten, héich Konzentratioun an héich Dispersibilitéit. Héichkonzentréiert Masterbatch kann den Zousatzbetrag reduzéieren, Produktioun Käschten reduzéieren, an héich Dispersibilitéit kann eenheetlech Faarf vu Plastiksprodukter garantéieren, vermeiden Faarf Flecken a Faarf Ënnerscheed, wat de Schlëssel ass fir d'Produktqualitéit ze verbesseren; véierten, Intelligenz an Automatisatioun vun der Veraarbechtung. Masterbatch Veraarbechtung erfuerdert strikt Kontroll vun der Mëschunguniformitéit, Temperatur an aner Parameteren. Intelligent, automatesch Zwilling-Schrauwen extrusion Produktioun Linnen wäert de Mainstream ginn, real-Zäit Iwwerwachung realiséieren, automatesch Parameter Upassung a Mass Produktioun, d'Produktiounseffizienz a Produktkonsistenz verbesseren.

Als Kär Veraarbechtung Equipement vun Masterbatch, Twin-Screw Extruders spillen eng entscheedend Roll an der Entwécklung vun der Masterbatch Industrie. Masterbatch Vermëschung huet strikt Ufuerderunge fir d'Vermëschung an d'Verdeelungseffekt, Temperatur Kontroll a Produktioun Effizienz vun extruders. Zhuoyue d'ganz Serie vun extruders (HTS BASIC/PLUS/SUPER, ZTE, HTE) si speziell fir Masterbatch Veraarbechtung entworf, mat cibléiert Leeschtung Virdeeler, déi effektiv d'Veraarbechtungsbedürfnisser vu verschiddenen Typen vu Masterbatch entspriechen an den Hiersteller hëllefen d'Produktqualitéit an d'Produktiounseffizienz ze verbesseren.

1.2 Kär Zesummesetzung an Aarbecht Prinzip vun Masterbatch

Masterbatch besteet aus dräi Basiselementer: Pigmenter oder Faarfstoffer, Träger an Zousatzstoffer. Den Undeel an d'Leeschtung vun all Element bestëmmen direkt d'Qualitéit an d'Benotzungseffekt vum Masterbatch. D'Kärkompositioun an d'Aarbechtsprinzip vu Masterbatch verstoen ass d'Basis fir seng Veraarbechtungstechnologie ze beherrschen an entspriechend Extrusiounsausrüstung ze wielen.

1.2.1 Pigmenter oder Faarfstoffer: De Core Coloring Komponent

Pigmenter oder Faarfstoffer sinn d'Kärkomponenten déi d'Masterbatch Faarfleistung ginn, Rechnung fir 10%-80% vun der Masterbatch Zesummesetzung (de spezifesche Verhältnis hänkt vun der Aart vu Pigment of, Faarf Ufuerderunge a Masterbatch Konzentratioun). Pigmenter ginn an organesch Pigmenter an anorganesch Pigmenter opgedeelt: organesch Pigmenter hunn helle Faarwen, héich tinting Kraaft, gutt Transparenz, awer schlecht Hëtzt Resistenz a Wieder Resistenz, haaptsächlech an niddreg Temperatur Veraarbechtung Plastik benotzt (wéi PE, PP) a Produite mat héich Faarf Ufuerderunge (wéi Textilien, Verpakung Filmer); anorganesch Pigmenter hunn eng gutt Hëtztbeständegkeet, Wiederresistenz a chemesch Stabilitéit, awer niddereg Tëntkraaft a schlecht Transparenz, haaptsächlech an héich-Temperatur Veraarbechtung Plastik benotzt (wéi Ingenieursplastik) an Outdoor Produiten (wéi Baumaterial, automobile Aussen- Deeler).

Faarfstoffer sinn anescht wéi Pigmenter. Faarfstoffer hunn eng gutt Solubilitéit a Plastiks Rohmaterialien, hell Faarwen an héich Transparenz, awer schlecht Hëtzt Resistenz a Liicht Resistenz, haaptsächlech an transparent Plastiksprodukter benotzt (wéi PET Fläschen, PC Blieder). D'Auswiel vu Pigmenter oder Faarfstoffer soll op der Aart vu Plastiks Rohmaterial baséieren (Veraarbechtungstemperatur), Produit benotzen Ëmfeld (bannen / dobaussen), Faarf Ufuerderunge (Faarf Hellegkeet, Transparenz) an Ëmweltschutz Ufuerderunge, fir sécherzestellen datt d'Masterbatch eng stabil Faarfleistung huet an de Gebrauchsufuerderunge vun Downstream Produkter entsprécht.

1.2.2 Träger: D'Dispersioun an Adhäsioun Komponent

Carrier sinn d'Matrix vu Masterbatch, Rechnung fir 10%-80% vun der Masterbatch Zesummesetzung, spillt haaptsächlech d'Roll fir Pigmenter/Faarwen ze verdeelen an un Plastiks Matière première ze halen. Den Träger muss gutt Kompatibilitéit mat béide Pigmenter / Faarfstoffer an den Zilplastik Rohmaterial hunn (d'Plastik Matière première ze faarweg), soss wäert et d'Dispergabilitéit vu Pigmenter an d'Faarfeffekt vu Produkter beaflossen. Allgemeng Trägermaterialien enthalen Polyethylen (PE), polypropylene (PP), polyvinylchlorid (PVC), polyamid (PA), polyethylene terephthalate (PET), etc., déi no der Zort vun Zil- Plastik Matière première ausgewielt ginn: zum Beispill, PE Carrier gëtt fir PE Plastik Faarwen benotzt, PP Carrier gëtt fir PP Plastikfaarwen benotzt, an PA Carrier gëtt fir Ingenieur Plastik PA Faarf benotzt.

Den Träger soll och gutt Veraarbechtungsfluiditéit hunn, wat zu der eenheetlecher Dispersioun vu Pigmenter bei der Extrusiounsveraarbechtung an der Vermëschung vu Masterbatch mat Zilplastik Matière première ass.. Zousätzlech, de Schmelzpunkt an d'Veraarbechtungstemperatur vum Träger solle konsequent mat oder liicht méi niddereg sinn wéi déi vun den Zilplastik Matière première, fir d'Zersetzung vum Träger oder dem Zilplastik während der Veraarbechtung ze vermeiden.

1.2.3 Zousätz: D'Auxiliary funktionell Komponent

Additive sinn Hilfskomponenten déi derbäigesat ginn fir d'Veraarbechtungsleistung ze verbesseren, dispersibility an benotzen Leeschtung vun masterbatch, Rechnung fir 1%-10% vun der Masterbatch Zesummesetzung. D'Art an d'Doséierung vun Additive ginn no der Aart vu Masterbatch a Veraarbechtungsfuerderunge festgeluegt. Gemeinsam Zousatzstoffer enthalen:

• Dispersant: Déi wichtegst Additiv am Masterbatch, wat d'Uewerflächespannung vu Pigmenter reduzéiere kann, Pigmentagglomeratioun verhënneren, a maachen Pigmenter gläichméisseg am Träger verdeelt. Allgemeng Dispergéierungsmëttel enthalen Polyethylenwachs, polypropylene Wachs, Stearinsäure, Kalziumstearat, etc. D'Zousatz vun Dispersanten kann d'Dispersibilitéit vum Masterbatch wesentlech verbesseren, suergen fir eenheetlech Faarf vu Produkter, a reduzéieren de Verschleiung vun Extrusiounsausrüstung.
• Kompatibilisatoren: Benotzt fir d'Kompatibilitéit tëscht Pigmenter an Träger ze verbesseren, an tëscht Masterbatch an Zil Plastik Matière première. Zum Beispill, wann den Träger an Zilplastik schlecht Kompatibilitéit hunn (wéi PE Carrier a PA Plastik), kompatibilizers (wéi Maleinanhydrid graféiert Polyethylen) kënne bäigefüügt ginn fir d'Verbindungskraaft tëscht hinnen ze verbesseren, vermeiden der Trennung vun masterbatch an Zil- Plastik während Veraarbechtung, a verbesseren d'mechanesch Eegeschafte vu Produkter.
• Hëtzt Stabilisatoren: Benotzt fir d'Zersetzung vu Pigmenter ze vermeiden, Träger an Zilplastik wärend der Héichtemperatur-Extrusiounsveraarbechtung. Allgemeng Hëtztstabilisatoren enthalen Bläi Salzer, Kalzium-Zink Stabilisatoren, organesch Zinnstabilisatoren, etc., déi ausgewielt ginn no der Veraarbechtungstemperatur an Ëmweltschutzfuerderunge.
• Liicht Stabilisatoren an Antioxidantien: Benotzt fir d'Wiederbeständegkeet an d'Alterungsresistenz vu Masterbatch a faarwege Plastikprodukter ze verbesseren, Vermeiden d'Faarfblecken an d'Leeschtungsdegradatioun vu Produkter ënner Sonneliicht a Sauerstoff, an de Service Liewen vun Produite verlängeren.
• Schmierstoff: Benotzt fir d'Reibung tëscht Materialien an Extrusiounsausrüstung ze reduzéieren (schrauwen, barrel, stierwen Kapp), verbessert d'Veraarbechtungsfluiditéit, Energieverbrauch reduzéieren, a vermeit datt Material un d'Ausrüstung hält, wat fir de glate Fortschrëtt vun der Extrusiounsveraarbechtung förderlech ass.

1.2.4 Aarbechtsprinzip vu Masterbatch

D'Aarbechtsprinzip vum Masterbatch baséiert op der eenheetlecher Dispersioun vu héichkonzentréiert Pigmenter am Carrier. Während der Veraarbechtung vu Plastiksprodukter, eng kleng Quantitéit vun masterbatch (normalerweis 1%-5%) gëtt mat onfaarwege Plastiks Rohmaterial gemëscht. Ënnert der Aktioun vun héijer Temperatur a Schéierkraaft während der Extrusioun oder Sprëtzformen, den Träger vun der Masterbatch schmëlzt a mëscht mat den Zilplastik Rohmaterialien, an déi eenheetlech verspreet Pigmenter ginn fräigelooss an gläichméisseg an der Zilplastikmatrix verdeelt, domat den Zweck erreechen fir Plastiksprodukter ze faarwen. De Schlëssel vun dësem Prozess ass datt d'Pigmenter an der Masterbatch eenheetlech musse verdeelt ginn ouni Agglomeratioun, soss gëtt et Faarf Flecken, Faarfdifferenz an aner Mängel an de faarwege Produkter.

1.3 Gemeinsam Klassifikatioun vun Masterbatch

Masterbatch kann a verschiddenen Typen opgedeelt ginn no verschiddene Klassifikatiounsnormen, wéi Faarftyp, Carrier Typ, Applikatioun Feld, funktionell Typ, etc. Déi richteg Klassifikatioun hëlleft d'Leeschtungseigenschaften an d'Veraarbechtungsfuerderunge vum Masterbatch besser ze verstoen, a wielt passenden extrusion Equipement a Veraarbechtung Techniken.

1.3.1 Klassifikatioun no Faarftyp

No der Aart vun der Faarfkomponent, masterbatch kann an Faarf masterbatch ënnerdeelt ginn, wäiss Masterbatch a schwaarz Masterbatch.

• Faarf Masterbatch: Déi meescht üblech Aart vu Masterbatch, déi organesch oder anorganesch Pigmenter vu verschiddene Faarwen benotzt (wéi rout, giel, blo, gréng, orange) als Faarfkomponenten, a gëtt benotzt fir Plastiksprodukter vu verschiddene Faarwen ze faarwen. D'Tëntstäerkt, Faarfhellegkeet an Dispersibilitéit vu Faarfmasterbatch sinn d'Schlësselindikatoren fir seng Qualitéit ze moossen.
• Wäiss Masterbatch: Benotzt Titandioxid (TiO2) als Haaptfaarfkomponent, et gëtt benotzt fir Plastiksprodukter ze wäissen oder als Basisfaarf fir hellfaarweg Masterbatch. D'Wäissheet, deckt Kraaft an Dispersibilitéit vu wäisse Masterbatch sinn d'Schlësselindikatoren. Titandioxid huet eng héich Härtheet, déi héich Ufuerderunge fir d'Verschleißbeständegkeet vun Extrusiounsausrüstung huet.
• Black Masterbatch: Benotzt Kueleschwarz als Haaptfaarfkomponent, et gëtt fir schwaarz Faarwen vu Plastiksprodukter benotzt. Carbon Black huet gutt UV Resistenz a Wieder Resistenz, a kann och d'mechanesch Eegeschafte vu Plastiksprodukter verbesseren. D'Dispersibilitéit vu Kueleschwarz ass de Schlëssel fir d'Qualitéit vu schwaarze Masterbatch. Schlecht Dispersibilitéit verursaache schwaarz Flecken a Sträifen a Produkter.

1.3.2 Klassifikatioun no Carrier Typ

Jee no der Zort vun Carrier, Masterbatch kann an PE Masterbatch opgedeelt ginn, PP masterbatch, PVC Masterbatch, PA masterbatch, PET Masterbatch, etc.

• PE Masterbatch: Benotzt PE als Carrier, et ass gëeegent fir PE Plastiksprodukter ze faarwen (wéi PE Filmer, PE Rohren, PE Sprëtz molding Deeler). Et huet gutt Kompatibilitéit mat PE Rohmaterialien, gutt Veraarbechtung Flëssegkeet an eenheetlech Faarf.
• PP Masterbatch: Benotzt PP als Carrier, et ass gëeegent fir PP Plastikprodukter ze faarwen (wéi PP Faseren, PP Sprëtz molding Deeler, PP Blieder). Et huet gutt Hëtzt Resistenz an ass gëeegent fir héich-Temperatur Veraarbechtung vun PP.
• PVC Masterbatch: Benotzt PVC als Träger, et ass gëeegent fir Faarf PVC Plastik Produiten (wéi PVC Päifen, PVC Profiler, PVC Filmer). Et muss mat PVC Hëtzt Stabilisatoren ugepasst ginn fir PVC Zersetzung während der Veraarbechtung ze vermeiden.
• Engineering Plastik Masterbatch: Benotzt Ingenieursplastik (PA, PC, PBT, etc.) als Träger, et ass gëeegent fir Ingenieursplastikprodukter ze faarwen (wéi Autosdeeler, elektresch Komponenten). Et huet gutt Hëtztbeständegkeet a Kompatibilitéit mat Ingenieursplastik, an huet héich Ufuerderunge op extrusion Veraarbechtung Equipement.

1.3.3 Klassifikatioun no Uwendungsfeld

Geméiss dem Uwendungsberäich vu Masterbatch, et kann an Faser Masterbatch opgedeelt ginn, Film Masterbatch, blow molding masterbatch, extrusion masterbatch, Sprëtz molding Masterbatch, etc., déi mat de fënnef grousse Applikatiounsfelder vum Masterbatch entspriechen.

• Fiber Masterbatch: Benotzt fir chemesch Faseren ze faarwen (wéi Polyesterfaser, Nylonfaser), déi an Teppecher benotzt gëtt, Textilien, Këssen an aner Produkter. Et erfuerdert héich Dispersibilitéit a Faarfschnellkeet, a kee Faarffading beim Spinnen a Weben.
• Film Masterbatch: Benotzt fir d'Faarwen vu Plastikfilmer (wéi Shopping Poschen, Casting Filmer, Multi-Layer Filmer), déi héich Transparenz an eenheetlech Faarf erfuerdert, a keng Faarf Flecken oder Sträifen op der Film Uewerfläch.
• Blow Molding Masterbatch: Benotzt fir Faarwen vu Schlagformprodukter (wéi medizinesch a kosmetesch Behälter, Schmieröl a Lackbehälter), wat eng gutt Veraarbechtungsfluiditéit an eenheetlech Faarf erfuerdert, a keng Verformung oder Faarfdifferenz vum Container.
• Extrusioun Masterbatch: Benotzt fir d'Faarwen vun Extrusiounsprodukter (wéi Blieder, Päifen, Drot a Kabelen), déi gutt Dimensiounsstabilitéit an eenheetlech Faarf erfuerdert, a kee Faarfdifferenz op der Produktoberfläche.
• Injection Molding Masterbatch: Benotzt fir Faarwen Sprëtz molding Produiten (wéi Autosdeeler, elektronesch Produkter, Baumaterial, doheem Apparater, Miwwelen, Spillsaachen), déi héich Dispersibilitéit a stabil Leeschtung erfuerdert, a kee Faarfdifferenz tëscht Chargen vu Produkter.

1.3.4 Klassifikatioun no funktionell Typ

No den zousätzleche Funktiounen vum Masterbatch, et kann an gewéinlech Masterbatch ënnerdeelt ginn (nëmmen Faarf Funktioun) a funktionell Masterbatch (faarweg + zousätzlech Funktiounen). Funktionell Masterbatch ass den Entwécklungstrend vun der Industrie, an allgemeng Zorte och flammretardant masterbatch, antistatesch Masterbatch, antibakteriell Masterbatch, UV-resistente Masterbatch, toughening masterbatch, etc. Funktionell Masterbatch erfuerdert entspriechend funktionell Zousatzstoffer op Basis vun engem gewéinleche Masterbatch, déi méi héich Ufuerderunge fir d'Mëschung an d'Verbreedungseffekt vun der Extrusiounsausrüstung huet.

2. Kär Veraarbechtung Technologie vun Masterbatch: Zwilling-Screw Extrusion Technology

Masterbatch Veraarbechtung enthält haaptsächlech Vermëschung, extrusion, ofkillen, Granulatioun an aner Prozesser, ënner deenen Zwilling-Schrauwen Extrusiounstechnologie ass d'Kärtechnologie vu Masterbatch Vermëschung a Granulatioun. Am Verglach mat Single-Screw Extrusion Technologie, Zwilling-Schrauwen Extrusiounstechnologie huet d'Virdeeler vu staarker Vermëschung an Dispergéierungskapazitéit, präzis Temperaturkontroll, kuerz Residenz Zäit, héich Produktiounseffizienz a staark Adaptabilitéit fir Matière première, déi effektiv d'Schlësselproblemer vun der Masterbatchveraarbechtung léisen (wéi Pigmentagglomeratioun, ongläiche Vermëschung, niddereg Produktioun Effizienz) a garantéieren d'Qualitéit vu Masterbatch Produkter.

Masterbatch Vermëschung ass eng vun den Haaptapplikatiounen vun Zwilling-Schrauwen-Extruderen. D'Qualitéit vum Masterbatch gëtt direkt vun der Leeschtung vum Twin-Screw Extruder an der Rationalitéit vum Veraarbechtungsprozess bestëmmt. D'Schlësselfuerderunge vun der Masterbatchveraarbechtung fir Zwilling-Schrauwen-Extruder sinn: staark Vermëschung an dispergéieren Effekt (fir eenheetlech Dispersioun vu Pigmenter ze garantéieren), präzis Temperaturkontroll (fir Pigment Zersetzung an Träger Degradatioun ze vermeiden), passende Schéierkraaft (Pigmentagglomeraten ze briechen ouni Pigmentpartikelen ze schueden), héich Produktioun Effizienz (Mass Produktioun Besoinen ze treffen) a gutt zouzedrécken Resistenz (unzepassen un d'Verschleiung vun héichhärte Pigmenter wéi Titandioxid a Kueleschwarz).

2.1 Veraarbechtung Schwieregkeeten vun Masterbatch an Ufuerderunge fir Extrusion Equipement

Obwuel Zwilling-Schrauwen Extrusiounstechnologie ass gëeegent fir Masterbatch Veraarbechtung, wéinst der Besonneschheet vun der Masterbatch Zesummesetzung (héich Pigment Inhalt, einfach Agglomeratioun vu Pigmenter) an Veraarbechtung Ufuerderunge (eenheetlech Dispersioun, stabil Leeschtung), et ginn nach vill Schwieregkeeten an der aktueller Veraarbechtung. D'Haaptveraarbechtungsschwieregkeeten an entspriechend Ufuerderunge fir Extrusiounsausrüstung sinn wéi follegt:

2.1.1 Pigment Agglomeratioun a schlecht Dispersibilitéit

Pigmenter (besonnesch anorganesch Pigmenter wéi Titandioxid a Kueleschwarz) hu staark Polaritéit a grouss spezifesch Uewerfläch, déi einfach a grouss Partikelen agglomeréieren wärend der Lagerung a Vermëschung. Wann d'Agglomerater net voll gebrach a verspreet kënne ginn während der Extrusiounsveraarbechtung, de Masterbatch wäert schlecht Dispersibilitéit hunn, an déi faarweg Plastiksprodukter wäerte Faarfflecken hunn, Faarfstreifen an ongläiche Faarwen, wat d'Produktqualitéit eescht beaflosst. Dëst ass déi heefegst a Schlëssel Schwieregkeet bei der Masterbatchveraarbechtung.

Dëst erfuerdert datt d'Extrusiounsausrüstung eng staark Vermëschung an Dispergéierungskapazitéit an eng passend Schéierkraaft huet. Den Zwilling-Schrauwen-Extruder soll eng intermeshing co-rotéierend Struktur adoptéieren, an d'Schraube soll mat genuch Mëschelementer a Schéierelementer ausgestatt sinn fir eng staark Schéierkraaft a Kneetkraaft während der Rotatioun ze generéieren, déi d'Pigmentagglomeraten komplett briechen an d'Pigmenter gläichméisseg am Träger verdeelen. Zousätzlech, d'Schraubegeschwindegkeet an d'Extrusiounsdrock solle justierbar sinn fir un verschidden Aarte vu Pigmenter a Masterbatch Konzentratioune unzepassen.

2.1.2 Pigment Zersetzung a Carrier Degradatioun verursaacht duerch Iwwerhëtzung

Déi meescht Pigmenter (besonnesch organesch Pigmenter) hunn schlecht Hëtzt Resistenz, an den Träger (wéi PE, PP) huet och eng gewësse Temperatur Resistenz Limite. Wann d'Extrusiounstemperatur ze héich ass oder d'Residenzzäit vum Material am Extruder ze laang ass, d'Pigment wäert zersetzen (doraus zu Faarf verbléien, Verfärbung), an den Träger wäert degradéieren (doraus zu reduzéierter mechanesch Eegeschafte vun der masterbatch). Dëst ass eng aner Schlësselschwieregkeet bei der Masterbatchveraarbechtung.

Dëst erfuerdert d'Extrusiounsausrüstung fir präzis Temperaturkontrollkapazitéit a kuerz Residenzzäit ze hunn. De Fass vum Extruder soll a verschidde Temperaturkontrollsektiounen opgedeelt ginn, an d'Temperatur vun all Sektioun soll präzis am optimalen Beräich kontrolléiert ginn (normalerweis 150-220 ℃ fir gewéinlech Masterbatch, 200-280℃ fir Ingenieur Plastik Masterbatch), mat enger Temperatur Kontroll Präzisioun vun ± 1 ℃. D'Schraubestruktur soll optimiséiert ginn fir d'Residenzzäit vum Material am Extruder ze verkierzen (normalerweis 1-3 Minutten), Vermeiden laangfristeg Kontakt tëscht dem Material an héich Temperatur.

2.1.3 Verschleiung vu Schrauwen a Faass verursaacht duerch High-Hardness Pigmenter

Anorganesch Pigmenter wéi Titandioxid a Kueleschwarz hunn héich Häert (Mohs Hardness 5-7), wat e seriöse Verschleiung fir d'Schraube an d'Fass vum Extruder während der Extrusiounsveraarbechtung verursaacht. Wann d'Schraube an d'Faass schlecht Verschleißbeständegkeet hunn, si wäerte séier gedroe ginn, doraus zu reduzéierter Schéierkraaft a Vermëschungskapazitéit vum Extruder, beaflosst d'Dispersibilitéit vum Masterbatch an d'Reduktioun vum Liewensdauer vun der Ausrüstung.

Dëst erfuerdert datt d'Schraube an d'Fass vum Extruder aus héichqualitativen verschleißbeständegen Materialien gemaach ginn an duerch fortgeschratt Fabrikatiounstechnologie veraarbecht ginn. Zum Beispill, d'Schraube an d'Faass kënnen aus importéierte verschleißbeständeg Legierungsstahl gemaach ginn, a bimetallesch Kompositbehandlung oder Laserbekleedung behandelen, wat d'Verschleißbeständegkeet an d'Korrosiounsbeständegkeet vun der Schraube a Faass staark verbesseren kann, an adaptéieren un d'Veraarbechtung vu Masterbatch mat High-hardness Pigmenter.

2.1.4 Onstabilitéit vun der Produktqualitéit tëscht Chargen

Masterbatch Veraarbechtung erfuerdert strikt Kontroll vu verschiddene Parameteren (wéi Formel Verhältnis, Vermëschung Zäit, extrusion Temperatur, Schrauwen Vitesse, fidderen Vitesse). Wann d'Parameteren schwankt, d'Qualitéit vum Masterbatch (wéi Konzentratioun, dispersibility, tinting Kraaft) wäert onbestänneg sinn, wat zu Faarfdifferenz tëscht Chargen vu faarwege Produkter resultéiert, wat de Ruff vum Hiersteller beaflosst.

Dëst erfuerdert d'Extrusiounsausrüstung fir intelligent Kontrollkapazitéit a stabil Leeschtung ze hunn. Den Extruder soll mat engem PLC intelligente Kontrollsystem ausgestatt sinn, déi präzis Kontroll vun der Fütterungsgeschwindegkeet realiséieren, Schrauwen Vitesse, Extrusiounstemperatur an aner Parameteren, a späichere verschidde Sätz vu Formelparameter. Wann Dir verschidde Chargen vu Masterbatch produzéiert, nëmmen déi entspriechend Parameteren mussen genannt ginn, widderholl Debugging vermeiden, garantéiert d'Stabilitéit vun der Produktqualitéit tëscht Chargen.

2.1.5 Héich Ufuerderunge fir Veraarbechtungsflëssegkeet

Masterbatch huet héich Pigment Inhalt, wat d'Veraarbechtungsfluiditéit vum Material reduzéiert. Wann d'Veraarbechtungsfluiditéit ze schlecht ass, d'Material wäert schwéier ginn ze vermëttelen an extrude, doraus zu niddereg Produktioun Effizienz, onbestänneg Extrusiounsdrock a souguer Ausrüstungsblockéierung.

Dëst erfuerdert datt d'Extrusiounsausrüstung eng staark Vermëttlungskapazitéit an eng justierbar Schéierkraaft huet. Den Zwilling-Schrauwen-Extruder soll e vernünfteg Schraube-Pitch adoptéieren, Lead a Kompressiounsverhältnis Design, an d'Schraube soll mat genuch Vermëttlungselementer ausgestatt sinn fir déi glat Transport vu Materialien ze garantéieren. Zousätzlech, d'Extrusiounstemperatur kann entspriechend ugepasst ginn fir d'Veraarbechtungsfluiditéit vum Material ze verbesseren, a Schmiermëttel kënne bäigefüügt ginn fir d'Reibung tëscht Materialien ze reduzéieren.

2.2 Aarbechtsprinzip a Prozess Flow vun Masterbatch Twin-Screw Extrusion

Den Zwilling-Schrauwen-Extrusiounsprozess vu Masterbatch ass e komplexe kierperleche Vermëschungsprozess, déi haaptsächlech Matière pretreatment ëmfaasst, premixing, fidderen, schmëlzen, vermëschen a schneiden, extrusion, ofkillen, granulatioun, Duerchmusterung a Verpakung. Den Haaptziel ass d'Pigmenter uniform ze verdeelen, Träger an Zousatzstoffer fir qualitativ héichwäerteg Masterbatch Granulat ze bilden. De spezifesche Aarbechtsprinzip an de Prozessfloss sinn wéi follegt:

2.2.1 Raw Material Pretreatment

Matière pretreatment ass d'Basis vun masterbatch extrusion Veraarbechtung, wat direkt de Vermëschungseffekt an d'Produktqualitéit beaflosst. D'Rohmaterialien vu Masterbatch enthalen haaptsächlech Pigmenter / Faarfstoffer, Träger, Zousätz (dispersants, kompatibilizers, Hëtzt Stabilisatoren, etc.). D'Schrëtt vun der Pretreatment sinn wéi follegt:

• Dréchent Behandlung: E puer Pigmenter (wéi organesch Pigmenter) an Träger (wéi PA, PET) hunn héich Waasserabsorptioun. Wann de Feuchtigkeitgehalt ze héich ass, et wäert Bubbles verursaachen, Agglomeratioun an aner Mängel am Masterbatch wärend der Extrusiounsveraarbechtung, a verursaache souguer hydrolytesch Degradatioun vum Träger. Dofir, d'Rohmaterialien musse virum Veraarbechtung getrocknegt ginn. D'Trocknungstemperatur an d'Zäit ginn no der Aart vu Rohmaterial bestëmmt: zum Beispill, organesch Pigmenter gi bei 60-80 ℃ getrocknegt fir 2-4 Stonnen, PE / PP Trägere sinn gedréchent bei 80-100 ℃ fir 3-5 Stonnen, an PA Trägere sinn gedréchent bei 100-120 ℃ fir 6-8 Stonnen. De Feuchtigkeitgehalt vun de gedréchent Matière première soll ënnert kontrolléiert ginn 0.1%.
• Zerstéieren a Séien: Fir Pigmenter mat grousser Partikelgréisst (wéi Titandioxid Agglomeraten) an Träger mat ongläiche Partikelgréisst, D'Kriischung an d'Siivbehandlung soll duerchgefouert ginn fir d'Uniformitéit vu Rohmaterialien ze garantéieren. D'Partikelgréisst vun de zerdréckte Rohmaterial soll kontrolléiert ginn 20-40 mesh, wat fir d'uniform Vermëschung vu Matière première an d'Breechung vu Pigmentagglomeraten bei der Extrusioun hëllefe.
• Onreinheetentfernung: Matière première kann Gëftstoffer enthalen (wéi Metallpartikelen, Steng, Stëbs) während Produktioun an Transport. Gëftstoffer beaflossen net nëmmen d'Qualitéit vum Masterbatch, awer droen och d'Schraube an d'Fass vum Extruder, a souguer Ausrüstungsblockéierung verursaachen. Dofir, d'Rohmaterial musse virum Gebrauch gefiltert a geläscht ginn, Benotzt e Filterbildschierm mat passenden Meshgréisst fir Gëftstoffer ze läschen.

2.2.2 Premixing

Premixing ass de Schlëssel Schrëtt fir d'Mëschung an Dispergéierungseffekt vu Masterbatch ze verbesseren. No der Formel Verhältnis, déi gedréchent, zerquetscht an Gëftstoffer-entfernt Pigmenter, Träger an Zousatzstoffer ginn an e High-Speed-Mischer gesat fir d'Virvermëschung. Den Zweck vun der Premëschung ass d'Pigmenter an d'Additive gläichméisseg un d'Uewerfläch vun den Trägerpartikelen ze halen, eng virleefeg Mëschung bilden, a leeën e Fundament fir déi eenheetlech Dispersioun während der Extrusioun.

D'Schlësselparameter vum Premixing sinn d'Mëschgeschwindegkeet, Mëschung Zäit a Mëschung Temperatur. D'Mëschgeschwindegkeet ass allgemeng 800-1200 rpm, d'Mëschung Zäit ass 5-10 Minutten, an d'Mëschtemperatur gëtt bei 40-60 ℃ kontrolléiert. Déi entspriechend Mëschtemperatur kann d'Haftung vun Zousatzstoffer verbesseren (wéi Dispergéierungsmëttel) op den Träger a Pigmenter, eenheetlech Vermëschung förderen. Fir Masterbatch mat héije Pigmentgehalt (wéi z 50% uewen), der Premixing Zäit kann entspriechend verlängert ginn, an eng kleng Quantitéit vun Dispersant kann als éischt derbäigesat ginn fir d'Dispergabilitéit vu Pigmenter ze verbesseren. No Premixing, d'Mëschung soll eenheetlech a Faarf sinn, ouni evident Pigmentagglomeraten an Additivpartikelen.

2.2.3 Füttern a Vermëttelen

Déi virgemëschte Mëschung gëtt an d'Fütterung vum Twin-Screw Extruder duerch e Schraubefeeder oder e Gürtelfeeder geschéckt. D'Fütterungsapparat vum Extruder ass normalerweis mat enger Frequenzkonversiounsgeschwindegkeetsreguléierungsfunktioun ausgestatt, déi d'Fütterungsgeschwindegkeet no der Schraubegeschwindegkeet an der Extrusiounsgeschwindegkeet upassen kann fir sécherzestellen datt d'Materialien an d'Extrusiounshuel stabil an eenheetlech erakommen, Vermeiden vun Material Akkumulation oder net genuch Ernierung.

D'Fütterung ass och mat engem Trockner ausgestatt (wéi eng elektresch Heizjacket) fir ze verhënneren, datt d'Rohmaterial beim Fudder erëm Feuchtigkeit absorbéiert. Fir Masterbatch mat héije Pigmentgehalt a schlechter Flëssegkeet, e gezwongene Fütterungsapparat kann ausgewielt ginn fir déi glat Ernierung vu Materialien ze garantéieren. Zousätzlech, der fidderen port vun extruder soll glat ginn, ouni dout Ecker, fir Material ze halen an Akkumulation ze vermeiden.

2.2.4 Schmelzen, Vermëschen a Scheren

D'Materialien, déi an d'Extrusiounskavitéit vum Zwilling-Schrauwen-Extruder erakommen, ginn kontinuéierlech vun de rotéierende Schrauwen no vir gedréckt. D'Extrusiounshöhle besteet aus enger Schraube an engem Faass, an de Volume vun der extrusion Kavitéit lues a lues laanscht d'Achs Richtung erof. Wann d'Schrauwen rotéieren, d'Materialien ginn graduell ënner der Handlung vun de Schrauwen an de Faass kompriméiert, an den Drock an der Extrusiounskavitéit geet graduell erop (allgemeng 5-12MPa).

Gläichzäiteg, d'Materialien si mat enger staarker Schéierkraaft a Reibungskraaft ausgesat, generéiert duerch d'relativ Bewegung tëscht de Schrauwen an dem Faass, wéi och tëscht de Schrauwen Flich. D'Schéierkraaft an d'Reibungskraaft kënnen d'Agglomerate vu Pigmenter komplett briechen, maachen d'Pigmenter gläichméisseg am geschmoltenen Träger verdeelt, a förderen d'Fusioun an d'Kompatibilitéit tëscht dem Pigment, Träger an Zousatzstoffer. D'Reibungskraaft kann och eng gewësse Quantitéit un Hëtzt generéieren, déi mat der externer Heizung vum Faass kombinéiert gëtt (elektresch Heizung oder Dampheizung) fir den Träger lues a lues ze schmëlzen a plastifizéieren.

De Faass vum Extruder gëtt normalerweis opgedeelt an 4-6 Temperatur Kontroll Sektiounen (fidderen Rubrik, Schmelzen Rubrik, Vermëschung Rubrik, homogenizing Rubrik, stierwen Kapp Rubrik), an d'Temperatur vun all Sektioun gëtt präzis kontrolléiert no der Aart vu Masterbatch (Carrier Typ, Pigmenttyp). Zum Beispill, wann Dir PE Masterbatch veraarbecht, 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℃. The precise temperature control can ensure that the carrier is fully melted without thermal decomposition, and the pigments are not decomposed or discolored.

The screw of the twin-screw extruder adopts a modular design, déi verschidde Schrauwenelementer fräi kombinéiere kënnen (such as conveying elements, vermëschen Elementer, shearing elements) according to the type of masterbatch. Zum Beispill, when processing masterbatch with high pigment content and easy agglomeration, more mixing elements and shearing elements can be configured to enhance the mixing and dispersing effect; when processing masterbatch with good fluidity, more conveying elements can be configured to improve production efficiency.

2.2.5 Extrusioun a Formen

Déi voll geschmoltenem, gemëscht a verspreet Material gëtt duerch d'Schrauwen op de Stierfkop vum Extruder gedréckt. De Stierfkop vum Masterbatch-Extruder ass normalerweis mat multiple kreesfërmege Stierflächer ausgestatt (d'Zuel an d'Gréisst vun de Stierflächer ginn no der Partikelgréisst vum Masterbatch bestëmmt). D'Material gëtt aus dem Stierfkop mat héijer Geschwindegkeet extrudéiert fir kontinuéierlech sträiffërmeg halleffäeg Produkter ze bilden (den Duerchmiesser vum Sträif ass normalerweis 2-5mm, déi no Clientsbedürfnisser ugepasst ka ginn).

D'Temperatur vum Stierfkapp ass liicht méi niddereg wéi déi vun der Homogeniséierungssektioun, wat kann verhënneren datt d'Material sech duerch exzessiv Temperatur zerstéiert an d'Formungseffekt vum Sträif garantéieren. D'Extrusiounsgeschwindegkeet gëtt kontrolléiert no der Aart vu Masterbatch an der Partikelgréisst Ufuerderung, allgemeng rangéiert vun 1-3m / min. Den Extrusiounsdrock soll stabil gehale ginn (Schwankungen bannent ± 0,5MPa), déi den eenheetlechen Duerchmiesser vum Sträif an d'Konsistenz vun der Masterbatch Qualitéit garantéieren.

2.2.6 Ofkillung a Solidifikatioun

Déi extrudéiert Sträif-förmlech halleffäeg Produkter ginn an e Kühlapparat geschéckt fir séier Ofkillung a Solidifikatioun. D'Kühlmethod fir Masterbatch ass normalerweis Waassertankkühlen, an d'Kältewaassertemperatur gëtt bei 20-30 ℃ kontrolléiert. D'Längt vum Killwasserbehälter ass 3-5 Meter, an d'Ofkillungszäit ass 2-4 Minutten. Rapid Ofkillung kann de Sträif séier solidiséieren, d'Form an d'Gréisst vum Sträif behalen, a vermeiden Verformung an Haftung.

Et sollt bemierkt datt d'Kühlgeschwindegkeet uniform ass. Wann d'Kühlgeschwindegkeet ze séier ass, den internen Stress vum Sträif wäert ze grouss sinn, an de Sträif gëtt brécheg an einfach ze briechen wärend der Granuléierung; wann d'Kühlgeschwindegkeet ze lues ass, de Sträif gëtt mëll an einfach ze halen, beaflosst de Granulatiounseffekt. No Ofkillung, d'Uewerfläch vum Sträif sollt trocken sinn, glat a fräi vu Blasen a Rëss.

2.2.7 Ausschneiden a Granulatioun

No Ofkillung a Verstäerkung, de Sträif gëtt an e Granulator geschéckt fir ze schneiden fir granulär Masterbatchprodukter ze bilden. De Granulator ass mat engem Rotatiounsmesser an engem fixe Messer ausgestatt, an d'Schneidgeschwindegkeet ass justierbar (allgemeng 500-1000 rpm). D'Partikelgréisst vun der Masterbatch gëtt kontrolléiert andeems d'Schneidgeschwindegkeet an d'Geschwindegkeet vum Sträiftransport ugepasst gëtt. 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.

The granulator should be equipped with a screening device to remove unqualified particles (wéi ze grouss, 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 Duerchmusterung, 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: Faarf (Uniformitéit, consistency with the standard sample), dispersibility (observed by microscope or test piece coloring), Konzentratioun (tinting strength test), Fiichtegkeet Inhalt, particle size distribution, etc. Only the masterbatch that meets the quality standards can be packaged.

The packaging of masterbatch adopts sealed and moisture-proof packaging (such as plastic woven bags with inner plastic film, aluminum foil bags), and the packaging weight is usually 25kg/bag or 50kg/bag. The packaging bag is marked with the product name, Modell, Faarf, Konzentratioun, Carrier Typ, Produktioun Datum, shelf life, manufacturer and other information. The packaged masterbatch should be stored in a dry, cool a gelëfter Lager, avoiding direct sunlight and moisture, and the shelf life is generally 6-12 Méint.

2.3 Key Factors Affecting Masterbatch Twin-Screw Extrusion Effect

The effect of twin-screw extrusion directly affects the quality of masterbatch (dispersibility, tinting Kraaft, stability). There are many factors affecting the extrusion effect, haaptsächlech mat Matière première Charakteristiken, Formel Verhältnis, premixing Effekt, 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 Matière première Charakteristiken

Den Typ, Partikelgréisst, 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, 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.

Zousätzlech, 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. The purity of raw materials is also very important; impurities in raw materials will not only affect the product quality, awer droen och d'Schraube an d'Fass vum Extruder.

2.3.2 Formula Ratio

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 Inhalt 50%-80%) can reduce the addition amount and production cost, but requires better dispersibility; low-concentration masterbatch (Pigment Inhalt 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 (kompatibilizers, Hëtzt Stabilisatoren, Schmierstoff) 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), Vermëschung Zäit (5-10 Minutten) and mixing temperature (40-60℃). Fir Masterbatch mat héije Pigmentgehalt, der Premixing Zäit kann entspriechend verlängert ginn, and the dispersant can be added first and mixed with the pigment, then mixed with the carrier and other additives. Zousätzlech, the premixed mixture should be inspected; if there are obvious pigment agglomerates, it should be crushed and remixed.

2.3.4 Extrusion Parameters

Extrusiounsparameter sinn déi wichtegst Faktoren, déi den Extrusiounseffekt beaflossen, haaptsächlech dorënner Schrauwen Vitesse, extrusion Temperatur an extrusion Drock.

• Schrauwen Speed: D'Schraubegeschwindegkeet vun Zwillingsschrauwen-Extruderen fir Masterbatchveraarbechtung reegelméisseg vu 200 zu 800 rpm. Wat méi héich ass d'Schraubegeschwindegkeet, wat méi grouss d'Schéierkraaft an d'Reibungskraaft vun de Materialien kritt, wat besser d'Vermëschung an d'Verbreedungseffekt vu Pigmenter ass, a wat méi héich d'Produktiounseffizienz ass. Allerdéngs, wann d'Schraubegeschwindegkeet ze héich ass, d'Residenzzäit vun de Materialien an der Extrusiounshöhle ass ze kuerz, resultéiert zu onvollstänneg Schmelz vum Träger, net genuch Vermëschung vu Materialien, an ongläich Dispersibilitéit; wann d'Schraubegeschwindegkeet ze niddreg ass, d'Schéierkraaft an d'Reibungskraaft sinn net genuch, d'Pigmentagglomeraten kënnen net komplett gebrach ginn, an d'Produktiounseffizienz ass niddereg.
• 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.
• Extrusion Temperature: 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 (Carrier Typ, Pigmenttyp). The temperature of the feeding section is lower (slightly higher than the drying temperature of the raw materials), 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℃. Zum Beispill, 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.
• Extrusioun Drock: 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. Allerdéngs, 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. Den Extrusiounsdrock soll stabil gehale ginn, 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, Temperatur Kontroll Präzisioun, zouzedrécken Resistenz, conveying capacity and intelligent control capacity. Zhuoyue d'ganz Serie vun extruders (HTS BASIC/PLUS/SUPER, ZTE, HTE) si speziell fir Masterbatch Veraarbechtung entworf, with excellent performance in these aspects, which can effectively meet the processing needs of different types of masterbatch.

3.1.1 Exzellent Mëschung an Dispergéierungseffekt

The core requirement of masterbatch processing is the uniform dispersion of pigments. All Zhuoyue's Zwilling-Schrauwen-Extruder adoptéieren eng intermeshing co-rotéierend Struktur, mat engem raisonnabel Schraube-Pitch, Lead a Kompressiounsverhältnis Design. D'Intermeshing an d'Rotatioun vun den Zwillingsschrauwen kënnen eng staark Schéierkraaft a Kneetkraaft generéieren, 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%, wat vill méi héich ass wéi déi vun gewéinleche Zwillingsschrauwen-Extruder (85%-90%).

Zousätzlech, the screws of all series of extruders adopt a modular design, which can freely combine different types of screw elements (Elementer ze vermëttelen, vermëschen Elementer, shearing elements) according to the type of masterbatch (such as color masterbatch, white masterbatch, black masterbatch) and pigment characteristics. Zum Beispill, when processing black masterbatch with carbon black (easy agglomeration), more mixing elements and shearing elements can be configured to enhance the mixing and dispersing effect; when processing color masterbatch with organic pigments (poor heat resistance), more conveying elements and fewer shearing elements can be configured to shorten the residence time and avoid pigment decomposition.

3.1.2 Präzis Temperaturkontroll, Avoiding Pigment Decomposition

Masterbatch processing has strict requirements on temperature control, an d'Temperaturfluktuatioun muss bannent ± 1 ℃ kontrolléiert ginn fir Pigmentzündung an Trägerdegradatioun ze vermeiden. All Zhuoyue d'extruders adoptéieren eng fortgeschratt intelligent Temperatur Kontroll System, déi aus héichpräzisen Temperatursensoren besteet, Heizelementer a Killelementer. De Faass ass opgedeelt an 4-6 onofhängeg Temperatur Kontroll Rubriken, an d'Temperatur vun all Sektioun kann präzis ugepasst a kontrolléiert ginn an Echtzäit.
