Masterbatch yog cov khoom siv xim xim sib xyaw ua ke nrog kev sib xyaw ua ke ntawm cov xim zoo nkauj, cov khoom siv tshwj xeeb, thiab cov khoom ntxiv. Nws yog dav siv hauv kev ua cov yas, roj hmab, thiab lwm yam ntaub ntawv polymer. Raws li ib qho tseem ceeb ntawm cov niaj hnub kev lag luam xim, masterbatch, nrog nws qhov zoo ntawm kev ntsuas qhov tseeb, tsis sib xws, thiab kev ua haujlwm yooj yim, tau dhau los ua cov kev daws teeb meem tseem ceeb los hloov cov hmoov qhuav los yog kua xim.
Los ntawm cov qauv kev xav, masterbatch feem ntau muaj peb ntu: cov xim, cov cab kuj, thiab cov khoom siv ntxiv. Cov xim tuaj yeem yog cov xim organic, xim tsis muaj xim, lossis xim xim, xaiv raws li lub hom phiaj xim thiab daim ntawv thov ib puag ncig. Cov cab kuj feem ntau yog cov polymer uas muaj kev sib raug zoo nrog cov khoom siv matrix, xws li polyethylene, polypropylene, thiab polystyrene, los xyuas kom meej tias cov masterbatch tuaj yeem ua tiav nrog cov matrix thaum lub sij hawm yaj. Functional additives muaj xws li dispersants, stabilizers, thiab antioxidants, siv los txhim kho kev ua haujlwm fluidity, tiv thaiv thermal degradation, thiab txhim kho xim ceev thiab huab cua tsis kam.
Cov yam ntxwv ntawm masterbatch feem ntau yog tshwm sim nyob rau hauv nws superior dispersibility. Los ntawm siab - shear mixing thiab precision granulation, colorants yog refined kom haum particle loj thiab uniformly encapsulated nyob rau hauv ib tug carrier. Thaum ua tiav tom qab, lawv sai depolymerize thiab faib tusyees thoob plaws matrix, txo cov xim sib txawv thiab qhov chaw tsis xws luag. Thib ob, masterbatches pab txhawb kev ntsuas thiab automated pub mis; lawv cov duab particle tso cai rau kom meej proportioning ntawm cov kab ntau lawm, txo tib neeg kev ua yuam kev thiab txhim kho ntau lawm efficiency thiab cov khoom sib xws. Tsis tas li ntawd, vim hais tias cov txheej txheem xim yog nyob rau hauv lub melting theem, plua plav paug thiab kev ua hauj lwm kev noj qab haus huv kev pheej hmoo raug txo kom tsawg, ib yam li cov volatile emissions ntawm cov kuab tshuaj los yog additives, raws li zoo raws li ntsuab manufacturing tiam sis.
Nyob rau ntawm daim ntawv thov, masterbatches tuaj yeem muab faib ntxiv raws li hom ntawm lub hauv paus cob, kev siv thev naus laus zis, thiab kev ua haujlwm, xws li qib txhaj tshuaj molding, qib tshuab moulding, qib spinning, thiab cov masterbatches sib xyaw nrog cov haujlwm tshwj xeeb xws li nplaim hluav taws xob, cov khoom siv hluav taws xob, thiab huab cua tsis kam. Lawv daim ntawv thov suav nrog ntau qhov kev lag luam suav nrog ntim khoom, tsheb, khoom siv hluav taws xob, khoom siv hauv tsev, thiab cov khoom siv niaj hnub, muab cov xim ruaj khov thiab txhim khu kev qha rau kev txhim kho cov khoom zoo thiab kev lees paub ntawm lub npe.
Zuag qhia tag nrho, xim masterbatches, nrog lawv cov xim zoo nkauj, kev ua haujlwm zoo thiab cov khoom zoo ib puag ncig, tau dhau los ua cov khoom tseem ceeb ntawm cov khoom siv polymer xim, thiab tab tom ua lub luag haujlwm tseem ceeb hauv kev txhawb kev ntse thiab huv hauv kev lag luam.
