Cov txheej txheem ntau lawm ntawm masterbatch

Cov txheej txheem ntau lawm ntawm cov xim masterbatch yog nruj heev, thiab cov txheej txheem ntub dej feem ntau yog siv.Cov xim masterbatch yog hauv av thiab theem-inverted los ntawm dej, thiab ib tug series ntawm kev ntsuam xyuas yuav tsum tau nqa tawm thaum lub pigment yog nyob rau hauv av, xws li kev txiav txim ntawm lub fineness, diffusion kev ua tau zoo, cov ntsiab lus thiab xim paste fineness ntawm sanding slurry.

Muaj plaub cov txheej txheem ntub dej rau cov xim masterbatch: txoj kev ntxuav, kneading txoj kev, hlau xab npum, thiab ink method.
(1) Cov txheej txheem ntxuav: Cov xim xim, dej thiab dispersant yog sanded kom cov xim particle me dua 1 teev tsaus ntuj, thiab cov xim hloov mus rau hauv cov roj theem los ntawm cov theem hloov pauv, thiab tom qab ntawd qhuav kom tau cov xim masterbatch.Cov kuab tshuaj organic thiab cov khoom siv hnyav hnyav rov qab yuav tsum tau ua rau theem inversion.Cov txheej txheem yog raws li nram no:
Pigment, dispersant, pab nyiaj - pob zeb - homogenization thiab stabilization kev kho mob - ziab - resin mixing - extrusion granulation xim masterbatch
(2) Kneading method Cov txheej txheem ntws ntawm txoj kev kneading yog raws li nram no:
Pigment, auxiliaries, resin kneading - lub cev qhuav dej - ziab - resin mixing - extrusion granulation rau hauv masterbatch
(3) Cov tshuaj xab npum hlau xim yog hauv av mus rau qhov loj me ntawm li 1um, thiab cov tshuaj xab npum yog ntxiv rau ntawm qhov kub thiab txias kom ua rau cov txheej txheem ntawm cov xim xim sib npaug sib npaug los ntawm cov tshuaj xab npum los tsim cov txheej txheem saponification. .Ntxiv cov tshuaj ntsev ntsev thiab qhov chaw ntawm cov xim.Cov txheej saponification chemically reacts los tsim ib tug tiv thaiv txheej ntawm hlau xab npum (magnesium stearate), thiaj li hais tias cov finely av pigment hais tsis flocculate.

Cov txheej txheem ntws ntawm hlau xab npum txoj kev yog raws li nram no:
Pigment, auxiliaries, dej sib tov - sib cais thiab lub cev qhuav dej - ziab - resin mixing - extrusion granulation rau hauv masterbatch
(4) Ink method Nyob rau hauv zus tau tej cov xim masterbatch, ntau lawm txoj kev ntawm number case xim muab tshuaj txhuam yog siv, uas yog, los ntawm peb-yob sib tsoo, ib tug tsawg molecular tiv thaiv txheej yog coated rau saum npoo ntawm cov xim.Cov milled zoo muab tshuaj txhuam yog tov nrog cov cab kuj, tom qab ntawd plasticized los ntawm twin-yob zeb, thiab thaum kawg granulated los ntawm ib leeg-ntsia hlau los yog ntxaib-ntsia hlau extruder.
Cov txheej txheem ntws yog raws li nram no:
Pigments, additives, dispersants, resins, hnyav cov khoom xyaw - peb-yob zeb xim paste - desolventizing - resin mixing - extrusion granulation rau hauv masterbatch.
Cov txheej txheem ntws qhuav ntawm cov xim masterbatch: pigment (los yog dye) auxiliary, dispersant, carrier - high-speed mixing, stirring thiab shearing - ntxaib-ntsia hlau extrusion granulation - txias txiav thiab granulation rau xim masterbatch
