Nyob rau hauv lub tshav pob ntawm plastics, kev siv cov additives thiab fillers yog ib qho tseem ceeb los txhim kho cov khoom thiab kev ua tau zoo ntawm cov khoom kawg. Titanium dioxide yog ib qho tshuaj ntxiv uas tau txais kev saib xyuas ntau. Thaum ntxiv raupolypropylene masterbatch, titanium dioxide tuaj yeem muab ntau yam txiaj ntsig, los ntawm kev txhim kho UV tiv thaiv kom zoo nkauj zoo nkauj.
Titanium dioxide yog ib txwm tshwm sim titanium oxide paub txog nws lub peev xwm los faib dawb, ci, thiab opacity rau ntau yam khoom. Hauvyas, nws feem ntau yog siv los ua cov xim kom ua tiav cov xim vibrant thiab muab kev tiv thaiv kev phom sij ntawm UV hluav taws xob. Rau polypropylene masterbatch, qhov sib ntxiv ntawm titanium dioxide tuaj yeem muaj kev cuam tshuam loj heev rau tag nrho cov khoom zoo kawg nkaus.
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm kev ntxiv titanium dioxide rau polypropylene masterbatch yog nws lub peev xwm los txhim kho UV tiv thaiv. Polypropylene yog ib qho nrov thermoplastic polymer paub txog nws txoj kev siv ntau yam thiab siv ntau yam kev siv los ntawm kev ntim khoom mus rau qhov chaw tsheb. Txawm li cas los xij, kev raug tshav ntuj ntev ntev tuaj yeem ua rau cov khoom degrade, uas ua rau muaj xim tsis zoo thiab txo cov khoom siv kho tshuab. Los ntawm kev sib koom ua ke ntawm titanium dioxide rau hauv cov masterbatch, cov khoom siv polypropylene tuaj yeem tiv thaiv kev puas tsuaj los ntawm UV hluav taws xob, txuas nws lub neej thiab tswj nws qhov kev pom zoo.
Tsis tas li ntawd, qhov sib ntxiv ntawmtitanium dioxidetuaj yeem txhim kho cov khoom zoo nkauj ntawm polypropylene masterbatch. Cov pigment ua raws li tus neeg sawv cev whitening, ua kom cov xim dawb thiab opacity ntawm cov khoom. Qhov no yog qhov tshwj xeeb tshaj yog nyob rau hauv cov ntawv thov uas yuav tsum muaj qhov zoo nkauj, zoo ib yam, xws li hauv kev tsim cov khoom siv, cov khoom siv hauv tsev thiab cov khoom siv kho mob. Qhov kev pom zoo ntxiv los ntawm kev siv titanium dioxide tuaj yeem ua rau kom pom tus nqi ntawm cov khoom kawg, ua rau lawv txaus nyiam rau cov neeg siv khoom thiab cov neeg siv khoom kawg.
Ntxiv nrog rau cov txiaj ntsig pom thiab kev tiv thaiv, titanium dioxide tuaj yeem txhim kho tag nrho cov kev ua tau zoo ntawm polypropylene masterbatches. Los ntawm kev ua kom zoo thiab cuam tshuam lub teeb, cov xim tuaj yeem pab txo cov cua sov hauv cov khoom siv, yog li pab txhim kho thermal stability. Qhov no yog qhov tseem ceeb tshwj xeeb hauv cov ntawv thov uas qhov kub tsis kam yog qhov tseem ceeb, xws li kev tsim cov khoom siv tsheb thiab cov khoom siv hluav taws xob.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias kev sib koom ua tiav ntawm titanium dioxide rau hauv polypropylene masterbatch yog nyob ntawm kev siv cov txheej txheem zoo masterbatch. Lub dispersion ntawm pigments nyob rau hauv lub polypropylene matrix yog qhov tseem ceeb los xyuas kom meej cov xim sib xws thiab kev ua haujlwm zoo. Yog li ntawd, cov neeg tsim khoom yuav tsum ua tib zoo xaiv ib tus neeg muag khoom masterbatch nrog kev txawj ntse thiab thev naus laus zis kom ua tiav qhov zoo sib xws thiab txhim khu kev qha titanium dioxide dispersion.
Hauv cov ntsiab lus, ntxiv titanium dioxide rau polypropylene masterbatch muaj ntau yam zoo, los ntawm kev txhim kho UV tiv thaiv kom zoo dua qub thiab ua haujlwm zoo. Raws li qhov kev thov rau cov khoom yas zoo, zoo nkauj thiab ruaj khov txuas ntxiv, lub luag haujlwm ntawm titanium dioxide hauv polypropylene masterbatches yuav dhau los ua qhov tseem ceeb. Los ntawm kev siv lub peev xwm ntawm cov xim ntau yam no, cov tuam ntxhab tuaj yeem txhim kho qhov zoo thiab kev ua lag luam ntawm lawv cov khoom polypropylene kom tau raws li cov kev xav tau ntawm ntau yam kev lag luam thiab cov neeg siv khoom.
