Titanium dioxide, feem ntau hu ua Tio2, yog ntau yam xim dawb siv nyob rau hauv ntau yam lag luam. Titanium dioxide rutile hmoov yog ib daim ntawv ntawm titanium dioxide uas yog tshwj xeeb tshaj yog muaj nqis rau nws siab refractive index thiab zoo heev lub teeb tawg zog. Nkag siab txog cov txheej txheem tsim khoom ntawm rutile titanium dioxide hmoov yog qhov tseem ceeb rau cov tuam ntxhab thiab cov neeg siv khoom kom nkag siab txog nws qhov zoo thiab kev siv.
Kev tsim cov rutile titanium dioxide hmoov muaj ob peb kauj ruam tseem ceeb, pib nrog kev rho tawm ntawm titanium ore, xws li ilmenite lossis rutile. Cov ores no tau ua tiav kom tau txais cov ntshiab titanium dioxide, uas yog ntxiv refined los tsim daim ntawv rutile yuav tsum tau. Hauv qab no yog ib qho kev piav qhia ntawm cov txheej txheem ntawm titanium dioxide rutile hmoov:
1. Ore extraction thiab purification: Thawj kauj ruam hauv kev tsim cov rutile titanium hmoov yog rho tawm titanium ore los ntawm cov pob zeb hauv av. Ilmenite thiab rutile yog qhov chaw tshaj plaws ntawm titanium dioxide. Tom qab cov ore tau txais, nws yuav tsum dhau los ntawm cov txheej txheem purification kom tshem tawm cov impurities thiab tau txais high-purity titanium dioxide concentrate.
2. Chlorination thiab oxidation: Lub purified titanium dioxide mloog zoo ces mus rau ib tug txheej txheem chlorination, reacting nrog chlorine los tsim titanium tetrachloride (TiCl4). Tom qab ntawd lub compound yog oxidized los tsim ib tug sib tov ntawm titanium dioxide thiab lwm yam by-products.
3. Hydrolysis thiab calcination: Lub resulting sib tov yog hydrolyzed rau precipitate titanium dioxide nyob rau hauv nws daim ntawv hydrated. Cov precipitate no ces calcined ntawm qhov kub thiab txias kom tshem tawm cov dej thiab hloov mus rau hauv lub rutile crystal qauv. Cov txheej txheem calcination yog qhov tseem ceeb hauv kev txiav txim siab cov khoom thiab qhov zoo ntawm qhov kawgrutile titanium dioxidehmoov.
4. Kev kho deg: Txhawm rau txhim kho qhov tawg thiab sib raug zoo ntawm rutile titanium dioxide hauv ntau daim ntawv thov, kev kho deg tuaj yeem ua tiav. Qhov no suav nrog txheej txheej ntawm cov khoom nrog inorganic lossis organic tebchaw los txhim kho lawv cov kev ua tau zoo thiab kev ruaj ntseg hauv cov qauv sib txawv.
5. Kev Tswjhwm Zoo thiab Ntim: Thoob plaws hauv tag nrho cov txheej txheem tsim khoom, kev tswj xyuas zoo yog siv los xyuas kom meej qhov purity, particle loj tis thiab lwm yam ntxwv tseem ceeb ntawm rutile titanium dioxide hmoov. Thaum cov hmoov ua tau raws li cov qauv xav tau, nws tau ntim thiab npaj rau kev faib rau cov neeg siv khoom kawg.
Kev tsim cov rutile titanium dioxide yuav tsum tau ceev faj tswj ntawm ntau yam tsis muaj, nrog rau kev xaiv raw khoom, txheej txheem txheej txheem thiab cov txheej txheem tom qab ua tiav. Cov neeg tsim khoom ua haujlwm txhawm rau txhim kho cov xwm txheej no kom tau txais qhov xav tau qhov loj me, cov qauv siv lead ua thiab cov khoom saum npoo kom tau raws li cov cai tshwj xeeb ntawm kev siv sib txawv.
Rutile titanium dioxide hmoov yog dav siv nyob rau hauv cov xim, coatings, yas thiab lwm yam khoom thiab muaj nuj nqis rau nws siab opacity, brightness thiab UV tiv thaiv zog. Los ntawm kev nkag siab txog cov txheej txheem tsim khoom ntawm rutile titanium dioxide hmoov, cov tuam ntxhab tuaj yeem kho nws cov khoom kom tau raws li qhov kev xav tau ntawm cov khoom kawg, thaum cov neeg siv khoom txaus siab rau qhov zoo thiab kev ua haujlwm ntawm cov xim dawb no tseem ceeb.
Hauv cov ntsiab lus, kev tsim cov rutiletitanium dioxide hmoovkoom nrog cov kauj ruam ntawm cov kauj ruam los ntawm kev rho tawm ore mus rau qhov chaw kho kom tsim tau cov xim zoo titanium dioxide nrog lub teeb tawg zoo heev. Qhov kev nkag siab no yog qhov tseem ceeb rau cov neeg tsim khoom thiab cov neeg siv kom paub txog tag nrho cov peev txheej ntawm titanium dioxide rutile hmoov hauv ntau daim ntawv thov.
