Txoj Kev Txhim Kho Dispersibility
Ua ntej, nruj tswj ntawm particle loj thiab particle loj tis.
Titanium dioxide particle loj thiab particle loj faib cov yam ntxwv yog complex thiab nyuaj rau kev nkag siab tag nrho, yog li cov txheej txheem hydrolysis thiab thev naus laus zis tuaj yeem txhim kho ua ntej kom ntseeg tau tias cov khoom sib xws ntawm cov qib qub. Qhov thib ob, kev tswj hwm qhov kub ntawm cov ntsiab lus tseem ceeb ntawm calcination tuaj yeem ntxiv dag zog kom cov titanium dioxide cov khoom loj tuaj. Thaum kawg, cov hmoov hmoov ntawm cov khoom tuaj yeem nqa tawm, thiab lub tshuab nqus tsev twj tso kua mis nrog kev ua haujlwm siab thiab cov txiaj ntsig zoo tuaj yeem xaiv los ntawm Raymond system kom ruaj khov ntawm cov yam ntxwv ntawm titanium dioxide.
Qhov thib ob, kev tswj xyuas nruj ntawm cov roj nqus thiab cov dej soluble.
Titanium dioxide roj nqus yog feem ntau muaj feem xyuam rau cov txheej txheem calcination calcination cua lossis calcination kub taw tes kub, yog tias tsis tswj kom zoo, yuav ua rau titanium dioxide particles lattice defects thiab particle shape irregularities, yog li ntawd, yuav tsum tswj qhov tsim nyog calcination kub, kho tus nqi. pub thiab kiln ceev tsim nyog match, txo cov particle lattice defects thiab particle tsis tu ncua geometric duab.
Thib peb, nruj me ntsis ua txoj haujlwm zoo ntawm kev kho deg.
Tam sim no, feem ntau ntawm cov neeg tsim xim hauv tsev los tsim cov coatings nrog anatase titanium dioxide, nws cov dispersion nyob rau hauv cov xim tsis zoo, nyob rau hauv cov ntsiab lus ntawm lub teb chaws tawm tswv yim ntawm huv kev lag luam, nws daim ntawv thov nyob rau hauv cov xim kev lag luam yog maj hloov los ntawm rutile titanium dioxide. Rau cov tuam txhab txheej tseem siv anatase titanium dioxide, kev kho deg tuaj yeem siv los hloov nws cov yam ntxwv saum npoo, xws li kev xaiv organosilicon, coupling nitrogen reagents lossis qee cov polyphosphates.
