Pigment dispersion yog ib qho tseem ceeb tab sis feem ntau underestimated kev sib tw hauv masterbatch ntau lawm. Tsis zoo dispersion tuaj yeem ua rau muaj teeb meem xws li cov xim tsis sib xws, cov ntxaij lim dej txhaws, fiber ntau tawg hauv spun fibers, thiab tsis muaj zog welded seams. Cov teeb meem no tsis tsuas yog cuam tshuam rau cov khoom zoo tab sis kuj ua rau cov nqi tsim khoom ntau dua vim cov xim siv ntau dua thiab cov tshuab poob qis. Hauv qab no yog cov lus qhia luv luv los daws cov teeb meem no kom zoo, raws li kev coj ua hauv kev lag luam:
1. Optimize Pigment Xaiv
Xaiv Cov Pigments sib xws: Xaiv cov xim uas sib haum nrog lub hauv paus polymer (piv txwv li, PE, PP, PET) kom ntseeg tau tias ntub dej thiab tawg.
Particle Size thiab Surface Treatment: Siv cov xim nrog cov khoom me me kom zoo dua dispersion. Cov xim pleev xim rau saum npoo (xws li, nrog cov khoom tawg lossis cov coatings) pab txo cov agglomeration thiab txhim kho cov khoom ntws.
Pigment Loading: Tsis txhob tshaj qhov pom zoo pigment load (feem ntau 20-40% rau organic pigments, 50-80% inorganic). Overloading yuav ua rau agglomeration thiab tsis zoo dispersion.
2. Txhim kho kev sib xyaw thiab kev sib xyaw ua ke
High-Shear Mixing: Siv ntxaib-ntsia hlau extruders los yog high-shear mixers los zom cov xim agglomerates. Kho cov ntsia hlau configuration (xws li, kneading blocks) kom zoo shear thiab txhim khu dispersion.
Kev sib xyaw ua ntej: Muab cov xim sib xyaw nrog cov khoom tawg lossis cov khoom thauj khoom ua ntej extrusion los txhim kho thawj zaug ntub dej thiab txo cov clumping.
Kev Tswj Kub Kub: Ua kom pom qhov kub zoo tshaj plaws kom tsis txhob muaj xim degradation lossis teeb meem viscosity. Rau cov xim kub-rhiab heev (piv txwv li, qee cov organic pigments), ua kom kub qis dua lawv qhov pib degradation.
3. Siv Dispersing Agents
Cov khoom siv ntxiv: Muab cov khoom sib cais xws li waxes, stearates, lossis polymeric dispersants (xws li, polyethylene wax, EVA-raws li additives) kom txo cov viscosity thiab txhim kho cov xim ntub dej.
Dosage: Feem ntau, siv 1-5% dispersant los ntawm qhov hnyav, nyob ntawm seb hom xim thiab kev thauj khoom. Kev siv ntau dhau tuaj yeem cuam tshuam tsis zoo rau txhua yam khoom thiab tuaj yeem ua rau tawg paj (qhov teeb meem tshwm sim saum npoo).
Novel Hyperdispersant rau Masterbatch: SILIKE SILIMER Series - Cov kev pabcuam ua haujlwm siab thiab cov neeg ua haujlwm dispersing.
SILIKE SILIMER SeriesKev Pab Cuam Tshuam thiab Dispersing Agentsyog lwm tiam silicone-raws li waxes (tseem hu ua Silicone Hyperdispersants) engineered kom xa superior pigment thiab muab tub lim dispersion nyob rau hauv masterbatch ntau lawm. Nws yog qhov zoo tagnrho rau cov xim concentrates, cov khoom sib xyaw ua ke, engineering plastics, thiab xav tau cov txheej txheem dispersion. Cov hyperdispersants no txhim khu kev ruaj ntseg thermal, rheology, thiab nqi zog thaum tshem tawm cov teeb meem kev tsiv teb tsaws chaw nrog cov tshuaj ntxiv (xws li, waxes, amides, esters).

4. Kho cov txheej txheem ua haujlwm
Ntsia Hlau Ceev: Ua kom cov ntsia hlau ceev (feem ntau 200-500 rpm) txhawm rau txhim kho shear thiab dispersion. Tsis txhob khiav ceev heev, vim qhov no tuaj yeem ua rau thermal degradation.
Lub Sijhawm Chaw Nyob: Ua kom zoo rau lub sijhawm nyob hauv extruder (feem ntau 30-60 vib nas this) kom paub meej sib xyaw yam tsis muaj cua sov.
Lim: Siv cov khoom siv tshuaj ntsuam (piv txwv li, 100-200 mesh) kom tshem tawm cov khoom tsis sib xws thiab xyuas kom zoo ib yam ntawm cov masterbatch zoo.
5. Chaw nyob cov khoom siv thiab kev tu vaj tse
Cov Khoom Siv Huv Huv: Tsis tu ncua ntxuav extruders, ntsia hlau, thiab tuag kom tsis txhob muaj kab mob los yog kev tsim cov khoom degraded uas cuam tshuam rau kev tawg.
Wear Check: Tshawb xyuas cov ntsia hlau thiab cov thoob rau hnav, vim tias cov khoom siv hnav txo qis kev ua haujlwm ntawm shear thiab ua rau tsis zoo dispersion.
Feeding Accuracy: Siv gravimetric feeders rau cov xim xim thiab resin dosing, kom ntseeg tau qhov sib xws ntawm cov xim dispersion.
