Kev tawg ntawm cov xim yog ib qho teeb meem tseem ceeb tab sis feem ntau tsis tau kwv yees hauv kev tsim cov masterbatch. Kev tawg tsis zoo tuaj yeem ua rau muaj teeb meem xws li kev faib xim tsis sib xws, cov lim dej txhaws, cov fiber tawg hauv cov fibers spinned, thiab cov seams welded tsis muaj zog. Cov teeb meem no tsis tsuas yog cuam tshuam rau qhov zoo ntawm cov khoom tab sis kuj ua rau cov nqi tsim khoom nce ntxiv vim muaj kev siv cov xim ntau dua thiab lub sijhawm tsis ua haujlwm ntawm cov tshuab. 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. Txhim Kho Kev Xaiv Xim
Xaiv Cov Xim Sib Xws: Xaiv cov xim uas sib xws nrog lub hauv paus polymer (piv txwv li, PE, PP, PET) kom ntseeg tau tias ntub thiab tawg zoo.
Qhov Loj ntawm Cov Khoom Me Me thiab Kev Kho Qhov Nto: Siv cov xim uas muaj cov khoom me me dua kom tau qhov sib kis zoo dua. Cov xim uas tau kho qhov nto (piv txwv li, nrog cov tshuaj sib kis lossis cov tshuaj pleev xim) pab txo qhov sib sau ua ke thiab txhim kho cov yam ntxwv ntawm kev ntws.
Kev Thauj Khoom Xim: Tsis txhob siv ntau tshaj qhov pom zoo ntawm cov xim (feem ntau yog 20-40% rau cov xim organic, 50-80% rau cov xim inorganic). Kev thauj khoom ntau dhau tuaj yeem ua rau muaj kev sib sau ua ke thiab kev sib kis tsis zoo.
2. Txhim Kho Kev Sib Tov thiab Kev Sib Xyaws
Kev Sib Tov Uas Muaj Zog Heev: Siv cov tshuab extruders uas muaj ob lub ntsia hlau los yog cov tshuab sib tov uas muaj zog heev los rhuav cov xim sib xyaw ua ke. Kho qhov kev teeb tsa ntawm cov ntsia hlau (piv txwv li, cov blocks kneading) kom ua kom zoo tshaj plaws ntawm kev sib tov thiab txhim kho kev sib kis.
Ua Ntej Sib Tov: Sib tov cov xim nrog cov dispersants lossis cov resins carrier ua ntej extrusion kom txhim kho thawj zaug ntub thiab txo qhov clumping.
Kev Tswj Kub: Tswj qhov kub thiab txias kom zoo tshaj plaws kom tsis txhob muaj xim puas tsuaj lossis teeb meem viscosity. Rau cov xim uas rhiab heev rau cua sov (piv txwv li, qee cov xim organic), tswj qhov kub thiab txias kom qis dua lawv qhov kev puas tsuaj.
3. Siv Cov Tshuaj Dispersing
Cov Khoom Ntxiv: Siv cov neeg sawv cev dispersing xws li waxes, stearates, lossis polymeric dispersants (piv txwv li, polyethylene wax, EVA-based additives) los txo qhov viscosity thiab txhim kho cov xim wetting.
Kev Siv Tshuaj: Feem ntau, siv 1-5% dispersant los ntawm qhov hnyav, nyob ntawm hom pigment thiab qhov hnyav. Kev siv ntau dhau tuaj yeem cuam tshuam tsis zoo rau cov khoom siv kho tshuab thiab ua rau tawg paj (qhov teeb meem ntawm qhov chaw).
Tshiab Hyperdispersant rau Masterbatch: SILIKE SILIMER Series - Cov khoom pab ua haujlwm siab thiab cov neeg sawv cev dispersing.
SILIKE SILIMER SeriesCov Khoom Pab Ua Khoom Thiab Cov Neeg Ua Haujlwm Dispersingyog cov roj hmab silicone tiam tom ntej (tseem hu ua Silicone Hyperdispersants) uas tau tsim los xa cov xim thiab cov khoom sib xyaw zoo tshaj plaws hauv kev tsim cov masterbatch. Nws zoo tagnrho rau cov xim concentrates, cov khoom sib xyaw, cov yas engineering, thiab cov txheej txheem sib xyaw uas xav tau kev kub ntxhov. Cov hyperdispersants no txhim kho kev ruaj khov thermal, rheology, thiab kev siv nyiaj txiag thaum tshem tawm cov teeb meem kev tsiv teb tsaws chaw uas feem ntau muaj nrog cov khoom siv ntxiv (piv txwv li, roj hmab, amides, esters).
