Kev xaiv ntawm cov ntaub ntawv masterbatch yog ib qho tseem ceeb ntawm kev txiav txim siab nws cov xim xim, kev ua kom haum, thiab cov khoom zoo kawg nkaus. Txij li thaum masterbatch yog tsim los ntawm cov xim, cov cab kuj, thiab cov khoom siv ntxiv, cov ntaub ntawv ntawm txhua yam tsis tsuas yog cuam tshuam rau dispersion thiab compatibility tab sis kuj muaj feem xyuam rau cov khoom zoo xws li kub tsis kam, huab cua tsis kam, thiab txhua yam stability. Hauv kev xaiv cov khoom siv tswv yim, kev tshuaj xyuas zoo raws li cov yam ntxwv ntawm matrix resin, kev siv tshuab, thiab kev siv ib puag ncig yog qhov tsim nyog kom ua tiav qhov kev pom zoo ntawm kev ua haujlwm thiab tus nqi.
Lub compatibility ntawm cov cab kuj yog qhov tseem ceeb. Cov cab kuj ntawm cov masterbatch yuav tsum zoo ib yam li cov polymer matrix uas yog xim nyob rau hauv cov nqe lus ntawm melting kub, viscosity, thiab polarity, yog li ua tau zoo miscibility thiab uniform dispersion thaum blending. Piv txwv li, polypropylene lossis zoo- cov khoom siv polyolefin tau haum rau polypropylene matrices, thaum polyester lossis hloov polyolefin cov cab kuj tuaj yeem siv rau cov tshuab polyester kom txo tau qhov kev pheej hmoo ntawm kev cuam tshuam cuam tshuam thiab yaj delamination. Yog tias qhov sib txawv ntawm cov cab kuj thiab cov matrix loj heev, nws tuaj yeem yooj yim ua rau tsis sib xws, xim streaks, lossis poob ntawm cov khoom siv kho tshuab.
Hom colorant txiav txim siab nws cov xim ntau thiab durability. Inorganic pigments, xws li titanium dioxide thiab hlau oxide-raws li pigments, muaj cua sov thiab huab cua tiv taus, ua rau lawv haum rau sab nraum zoov lossis siab - qhov kub thiab txias. Organic pigments muab cov xim vibrant thiab siab pob tshab, ua rau lawv haum rau cov khoom siv sab hauv tsev uas yuav tsum muaj xim ci ntsa iab. Thaum cov dyes muaj ntau yam xim, lawv muaj kev cuam tshuam rau kev tsiv teb tsaws thiab thermal decomposition hauv cov yas, yog li lawv feem ntau yog siv rau hauv tshwj xeeb qis - kub lossis luv - daim ntawv thov. Thaum xaiv cov dyes, yam xws li lub teeb, av noo, thiab tshuaj lom neeg nyob rau hauv cov khoom lag luam ib puag ncig yuav tsum tau txiav txim siab, nrog rau kev ntsuam xyuas ntawm cov xim ceev thiab tiv thaiv - muaj peev xwm laus.
Cov khoom siv ntawm cov khoom siv ntxiv kuj cuam tshuam rau kev ua haujlwm thiab kev ruaj ntseg ntawm masterbatches. Dispersants tuaj yeem txhim kho qhov kev faib tawm ntawm cov xim pigment hauv cov cab kuj thiab txo cov yaj shear load; Cov tshuaj tiv thaiv kab mob antioxidants thiab cov cua sov stabilizers tuaj yeem cuam tshuam cov kev cuam tshuam degradation thaum lub sij hawm ua haujlwm siab -kub, txuas ntxiv lub neej kev pab cuam ntawm masterbatches thiab cov khoom. Rau cov txheej txheem sib txawv, xws li kev txhaj tshuaj molding, extrusion, tshuab moulding, lossis spinning, cov txheej txheem ntxiv rau cov txheej txheem yuav tsum raug xaiv los xyuas kom meej lub qhov rais ua haujlwm dav thiab kev ua haujlwm ruaj khov.
Tsis tas li ntawd, kev tiv thaiv ib puag ncig thiab kev tswj hwm kev ua raws cai tau dhau los ua qhov tseem ceeb hauv kev xaiv cov khoom siv. Pigments thiab additives uas tsis tshua muaj toxicity thiab tsis muaj cov tshuaj txwv tsis pub yuav tsum tau ua ntej kom ua tau raws li cov qauv kev lag luam rau kev sib cuag zaub mov, khoom ua si, thiab khoom siv hluav taws xob, yog li txo qis kev nyab xeeb thiab kev pheej hmoo ntawm kev lag luam.
Feem ntau, kev xaiv cov ntaub ntawv masterbatch yuav tsum muaj qhov sib npaug ntawm cov cab kuj sib raug zoo, kev ua haujlwm xim, kev ua haujlwm ntxiv, thiab kev ua raws cai. Los ntawm kev tsim qauv tsim, masterbatches tuaj yeem ua tiav lawv cov dispersion thiab xim zoo thaum ua, muab cov khoom lav rau qhov zoo thiab kev ntseeg siab ntawm cov khoom kawg.
