Titanium Dioxide siv nyob rau hauv ceramics
Ceramic qib titanium dioxide yog ib tug subdivision ntawm anatase titanium dioxide, uas yog ib tug ntawm ob lub ntsiab ntau yam ntawm titanium dioxide, nrog siab purity, uniform particle loj, siab refractive index, zoo heev kub kuj, thiab tsis tig grey nyob rau hauv 1 teev nyob rau hauv qhov kub ntawm 1200 degrees. Nrog siab opacity, nyias txheej thiab lub teeb yuag, nws yog dav siv hauv ceramics, kev tsim kho, kho kom zoo nkauj thiab lwm yam ntaub ntawv.
Ceramic qib titanium dioxide muaj purity siab, zoo whiteness, ci xim, tsis zoo particle loj, muaj zog refractive Performance index thiab siab achromatic zog, siv nws siab refractive Performance index yuav tau zoo whiteness thiab opacity, thiab yuav txhim kho lub refractive index, haum rau lub chaw tsim tshuaj paus. ntawm cov khoom siv hauv tsev nrog cov xim hauv pem teb, cov vuas iav, cov plooj (porcelain plates), cov ntaub ntawv tshwj xeeb refractory, tableware, sanitary ware thiab ceramic crafts.
Kev tsim cov txheej txheem ntawm ceramic qib titanium dioxide yog qhov tseem ceeb tib yam li txhua yam ntawm anatase titanium dioxide, uas yog cov txheej txheem tsim sulfuric acid. Sulfuric acid titanium dioxide yog ua los ntawm titanium tov los ntawm decomposing ilmenite nrog muaj sulfuric acid, thiab ces ua rau hydrated titanium dioxide (metatitanic acid) tom qab purification thiab hydrolysis, thiab ntxiv purified metatitanic acid kom tshem tawm ntau yam impurities xws li hlau thiab calcined lub cev qhuav dej, desulfurization. , thiab crystalline transformation rau hauv titanium dioxide puag cov khoom, uas yuav crushed raws li ib yam khoom uas tsis muaj tom qab ua, los yog tom qab sib tsoo thiab dispersion ntxiv, xaiv dej, txheej txheej kho, ziab, thiab precision crushing ua ib yam khoom. Qhov no yog titanium dioxide tsim los ntawm txoj kev ntub dej, uas yog sulfuric acid titanium dioxide; nws yog txheej txheem ntau lawm los ntawm txoj kev qhuav ntawm chlorinated titanium dioxide. Txoj kev sulfuric acid tuaj yeem tsim tau ob qho tib si anatase titanium dioxide thiab rutile titanium dioxide, uas tau dhau los ua cov txheej txheem qub qub.
