Titanium Dioxide(TiO2) yog ib qho xim ntau ntau siv nyob rau ntau yam kev lag luam, suav nrog cov xim av, suav nrog cov xim av, cov plastics thiab tshuaj pleev ib ce. Nws cov khoom tshwj xeeb ua rau nws cov khoom tseem ceeb hauv kev ua tiav xim, opacity thiab UV tiv thaiv. Txawm li cas los xij, kom paub cov peev txheej tag nrho ntawm TiO2 hmoov, ua tau zoo dispersion yog qhov tseem ceeb heev. Kev tsim kho kom zoo txawm tias kev faib tawm thiab siab tshaj plaws siv cov pigments, uas ua rau cov nyiaj txuag thiab txhim kho cov khoom ua haujlwm.
Ib qho ntawm cov kev sib tw tseem ceeb hauv kev siv TiO2 hmoov yog ua tiav cov kev sib cais tsis sib xws. Cov neeg tsis zoo ua rau tsis muaj qhov ua tsis tau, txo cov opacity, thiab txo cov khoom lag luam zoo. Txhawm rau hais txog qhov teeb meem no, cov chaw tsim khoom thiab cov kws tshawb nrhiav tau tshawb txog kev siv Tio2 hmoov zoo los ntawm kev siv thev naus laus zis siv tau zoo.
Ib txoj hauv kev zoo los txhim kho TIO2 dispersion yog siv cov khoom tiav expersion khoom. Kev kub ceev dispersers, hlaws mills, thiab ultrasonic homogenizers feem ntau siv cov cuab yeej kom ua tiav Tio2 cov khoom sib txuam loj me me hauv ntau yam kua thiab khoom matrices. Cov cuab yeej siv tau pab thaum muaj agglomerates thiab ntub dej ntawm TiO2 hais, yog li kev txhim kho cov dispersion thiab kev ua haujlwm ntawm cov khoom kawg.
Ntxiv rau rau cov khoom siv siab dua, xaiv txoj cai tsis txaus yog tseem ceeb heev rau kev siv Tio2 hmoov. Dispersants, xws li surfactants thiab polymer additives, ua si ib lub luag haujlwm tseem ceeb, tiv thaiv kev rov ua dua tshiab thiab txhawb nqa cov nplaum kom lub substrate. Los ntawm ua tib zoo xaiv cov ntaub ntawv tshwj xeeb raws li cov ntaub ntawv tshwj xeeb thiab malrix, cov chaw tsim khoom tuaj yeem ua tiav kev sib tawg ntawm tiio2 hmoov thiab txhim kho nws cov kev ua tau zoo.
Ib qho ntxiv, kev sib xyaw ua ke ntawm kev kho mob saum npoo muaj peev xwm cuam tshuam ntau yam cuam tshuam cov dispersion thiab siv tau ntawm TiO2 hmoov. Cov txheej txheem kev hloov kho deg, xws li kev kho kom zoo thiab alumina txheej, tuaj yeem txhim kho qhov sib xws ntawm TiO2 nrog cov sib txawv ntawm kev sib cais thiab cov nplaum. Cov kev kho hauv cov npoo npoo no tseem pab txhim kho huab cua tsis kam thiab kav ntev ntawm ti2-muaj ntau dua rau kev siv sab nraum zoov.
Lwm qhov ntawm kev siv kev sivTio2 hmoovPuas yog kev txhim kho kev sib cais daws teeb meem rau cov kev siv tshwj xeeb. Cov kev lag luam sib txawv thiab cov khoom lag luam xav tau cov tswv yim sib txawv kom ua tiav kev ua tau zoo. Piv txwv li, hauv cov xim pleev xim rau kev lag luam thiab kev lag luam Titanium Dioxide dispersions thiab cais cov khoom txaus siab thiab tiv thaiv kev daws teeb meem, ua kom muaj xim zoo sib xws thiab cov kev pab them nqi. Ib yam li ntawd, hauv kev lag luam plastics, masterbatch ua qauv nrog kev ua kom zoo nkauj tio2 thiab kho qhov muag ntawm cov khoom kawg.
Hauv cov ntsiab lus, ua kom zoo siv tio2 hmoov los ntawm kev rhuav tshem yog qhov tseem ceeb rau kev ua tau zoo rau ntau cov ntawv thov. Los ntawm kev siv cov khoom siv expmersion, kev xaiv cov thev naus laus zis thiab customating dispersion, tuaj yeem ua tiav nws cov kev ua tau zoo hauv cov khoom kawg. Cov tswv yim no tsis tsuas pab txuag tus nqi thiab txhim kho cov khoom lag luam zoo thiab kev nce qib ntawm cov khoom lag luam titanium dioxide.
