Hauv kev siv txheej txheej, qhov sib txawv ntawm Sulphate thiab Chloride Titanium Dioxide
Kev lag luam txheej yog cov neeg siv ntau tshaj plaws ntawm titanium dioxide, tshwj xeeb tshaj yog rutile titanium dioxide, feem ntau yog siv los ntawm kev lag luam txheej. Kev lag luam txheej thoob ntiaj teb siv TiO2 suav txog 58 feem pua mus rau 60 feem pua ntawm tag nrho cov khoom siv titanium dioxide pigments, Tuam Tshoj kev noj ntawm qhov kev faib ua feem ntau dua, txog 60 feem pua rau 65 feem pua los yog li ntawd.
Titanium dioxide yog ib qho ntawm cov xim siv ntau tshaj plaws hauv kev lag luam txheej, suav txog ib nrab ntawm cov nqi ntawm cov xim pleev xim, thiab nws cov khoom siv hauv kev lag luam txheej yog 90 feem pua ntawm tag nrho cov khoom siv ntawm ntau yam xim hauv kev lag luam txheej thiab 10 feem pua 25 feem pua ntawm cov nqi ntawm lub tsho tiv no raw khoom.
Raws li peb txhua tus paub, cov txheej txheem ntawm titanium dioxide feem ntau muab faib ua cov txheej txheem sulphate thiab cov txheej txheem chloride, ob qho tib si vim yog cov khoom sib txawv ntawm cov khoom siv raw thiab cov txheej txheem txheej txheem, uas ua rau kev ua haujlwm ntawm cov khoom muaj nws tus kheej zoo thiab qhov tsis zoo. Raws li cov yam ntxwv ntawm cov txheej txheem sib txawv, titanium dioxide weatherability, kev pab them nqi, kev zoo nkauj, dispersion muaj cov kev cai sib txawv, daim ntawv thov ntawm ob txoj kev sib txawv ntawm sulfuric acid txoj kev thiab chloride txoj kev yog raws li nram no:
* Raws li kev siv ntau, sulfate rutile feem ntau yog 5 feem pua rau 15 feem pua ntau tshaj li chloride rutile.
* Nyob rau hauv cov nqe lus ntawm dispersibility, sulphate rutile yog hais txog 10 feem pua phem tshaj li chloride rutile.
* Hais txog lub hwj chim npog, chloride rutile titanium dioxide yog 10 feem pua rau 15 feem pua siab dua sulphate rutile.
* Nyob rau hauv cov nqe lus ntawm cov khoom nto, fluidity, yellowing kuj, thiab xim sib tov stability, chloride rutile titanium dioxide zoo dua sulphate rutile titanium dioxide.
Raws li qhov yuav tsum tau ua ntawm txheej txheej, nws yog ib qho tseem ceeb uas yuav tsum xaiv hom titanium dioxide uas tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm txheej txheej thiab txheej txheej zaj duab xis. Los ntawm kev sib piv, nws tuaj yeem pom tau tias tam sim no titanium dioxide yog qhov zoo tshaj plaws rutile titanium dioxide cov khoom tsim los ntawm cov txheej txheem chloride, uas yog cov xim dawb zoo tshaj plaws nyob rau hauv kev ua lag luam tam sim no, nrog rau tag nrho cov kev ua tau zoo, thiab yog cov xim dawb nyiam nyob rau hauv coatings. , nrog rau cov xim tsim nyog rau lub teeb xim coatings. Vim muaj cov txheej txheem kev kho deg sib txawv, muaj ntau hom titanium dioxide, koj tuaj yeem xaiv cov hom tshwj xeeb raws li cov yam ntxwv ntawm cov xim pleev xim, xws li seb yuav xav tau siab gloss, lossis siab npog lub zog, lossis siab tiv thaiv hmoov av. .
