Titanium dioxide(TiO2) yog ntau yam thiab dav siv cov xim dawb paub txog nws qhov tshwj xeeb ci ci thiab siab refractive index. Nws yog dav siv nyob rau hauv ntau yam kev siv xws li xim, coatings, plastics thiab tshuaj pleev ib ce. Txhawm rau kom paub txog tag nrho cov peev txheej ntawm TiO2 hmoov, nws yog ib qho tseem ceeb kom nkag siab txog cov kev coj ua zoo tshaj plaws rau nws daim ntawv thov thiab kev tawg.
Ib lub ntsiabkev siv ntawm titanium dioxideyog nyob rau hauv formulation ntawm cov xim thiab coatings. TiO2 hmoov muaj nuj nqis rau nws lub peev xwm los muab qhov zoo tshaj plaws opacity thiab whiteness rau cov khoom tiav. Txawm li cas los xij, txhawm rau kom ua tiav qhov kev ua tau zoo, nws yog ib qho tseem ceeb kom ntseeg tau tias TiO2 cov khoom tawg tau zoo nyob hauv cov xim los yog txheej txheej. Qhov no tuaj yeem ua tiav los ntawm kev siv cov txheej txheem zoo titanium dioxide dispersion, xws li kev sib xyaw ua haujlwm siab lossis kev tshaj tawm milling, uas pab cuam tshuam cov agglomerates thiab xyuas kom cov xim sib npaug sib npaug hauv cov matrix.
Ntxiv nrog rau cov xim thiab cov txheej txheem, titanium dioxide yog siv dav hauv kev lag luam yas. Thaum sib xyaw TiO2 hmoov rau hauv cov yas formulations, nws yog ib qho tseem ceeb uas yuav tau xyuam xim rau cov xim particle loj thiab kev kho deg. Cov me me me me thiab kev kho saum npoo tuaj yeem txhim kho qhov tawg ntawm TiO2 hauv cov yas matrix, yog li txhim kho opacity thiab tiv thaiv UV. Tsis tas li ntawd, cov txheej txheem kev sib xyaw kom raug thiab kev ua tiav yog qhov tseem ceeb los xyuas kom meej tias cov xim sib npaug sib npaug thoob plaws hauv cov yas resin.
Lwm daim ntawv thov tseem ceeb ntawm titanium dioxide yog nyob rau hauv kev lag luam tshuaj pleev ib ce. Titanium dioxide hmoov feem ntau yog siv rau hauv cov tshuaj pleev thaiv hnub ua lub lim dej UV zoo heev. Txhawm rau kom ua tiav qib siab ntawm kev tiv thaiv hnub ci, nws yog ib qho tseem ceeb uas TiO2 cov khoom sib npaug sib npaug hauv cov qauv tiv thaiv hnub ci. Qhov no tuaj yeem ua tiav los ntawm kev siv cov cuab yeej tshwj xeeb dispersing thiab cov txheej txheem sib xyaw kom zoo, uas pab tiv thaiv kev tsim cov agglomerates thiab xyuas kom meej txawm tias faib cov pigments.
Thaum sivTiO2 hmoov, nws yog ib qho tseem ceeb uas yuav tau xav txog cov kev cai tshwj xeeb ntawm daim ntawv thov npaj. Txawv kev lag luam thiab formulations yuav tsum tau sib txawv dispersion thiab daim ntawv thov txoj kev. Piv txwv li, nyob rau hauv cov dej-raws li systems, kev siv wetting thiab dispersing agents yuav pab txhim kho dispersion ntawm TiO2 hais. Ib yam li ntawd, nyob rau hauv cov kuab tshuaj raws li cov txheej txheem, kev xaiv cov kuab tshuaj thiab dispersion tshuab tuaj yeem muaj kev cuam tshuam loj rau cov xim ua haujlwm.
Hauv cov ntsiab lus, kev qhib lub peev xwm ntawm TiO2 hmoov yuav tsum muaj kev nkag siab zoo ntawm nws daim ntawv thov thiab kev ua haujlwm zoo tshaj plaws. Txawm hais tias siv rau hauv cov xim, coatings, plastics lossis tshuaj pleev ib ce, cov txheej txheem dispersion kom zoo yog qhov tseem ceeb rau kev ua haujlwm zoo ntawm titanium dioxide. Los ntawm kev tsom mus rau yam xws li qhov loj me, kev kho saum npoo thiab cov txheej txheem dispersion, cov tuam ntxhab tuaj yeem ua kom muaj txiaj ntsig zoo ntawm TiO2 hmoov hauv lawv cov qauv thiab cov khoom.
