Titanium Dioxide (TiO2) yog qhov tseem ceeb inorgacic tshuaj lom neeg cov tshuaj, uas muaj cov tshuaj yas, tshuaj yas, cov tshuaj yas, ceramics thiab lwm yam kev lag luam. Titanium Dioxide (English Lub Npe: Titanium Dioxide) yog xim dawb uas nws lub ntsiab tiv no yog Titanium Dioxide (Tio2). Lub npe scientific yog Titanium Dioxide (Titanium Dioxide), thiab cov mis molecular yog TiO2. Nws yog polycrystalline cov compound uas cov nplooj yog cov teeb tsa thiab muaj ib tug lattim qauv. Tus txheeb ze qhov ceev ntawm titanium dioxide yog qhov me tshaj. Cov txheej txheem ntau lawm ntawm Titanium Dioxide muaj ob txoj kev txheej txheem: sulfuric acid qauv thiab chlorination txoj kev.
Lub ntsiab nta:
1) cov txheeb ze ua kom ceev
Ntawm cov feem ntau siv cov xim dawb, cov txheeb ze qhov sib txheeb ntawm titanium dioxide yog qhov me tshaj. Ntawm cov pigments dawb ntawm tib qho zoo, thaj tsam ntawm cov titanium dioxide yog qhov loj tshaj plaws thiab cov xim xim yog qhov loj tshaj plaws.
2) Melting taw tes thiab boiling taw tes
Txij li thaum lub anatase hom hloov mus rau hom rutile nyob kub, lub zog melting thiab boiling taw tes ntawm anatase titiium dioxide tsis muaj tiag. Tsuas yog rutile titanium dioxide muaj lub ntsiab lus melting thiab boiling point. Lub ntsiab lus melting ntawm rutile dioxide yog 1850 ° C, lub suab nrov hauv cov pa-nplua nuj yog 18) ° Lub Bushing taw tes ntawm rutile dioxide yog (3200 ± 300) ° C, thiab titanium Dioxide yog qhov tsis muaj me ntsis volatile ntawm qhov kub siab.
3) dielectric constant
Titanium Dioxide muaj hluav taws xob hluav taws xob zoo vim nws cov dielectric tas li. Thaum txiav txim siab qee qhov khoom ntawm titanium dioxide, lub crystallographic kev taw qhia ntawm titanium dioxide muaju yuav tsum tau txiav txim siab. Dielectric constant ntawm anatase titanium dioxide yog qhov tsawg, tsuas yog 48.
4) Ua haujlwm
Titanium Dioxide muaj semiconductor thaj chaw, nws qhov kev coj ua tau nce sai nrog qhov kub thiab txias, thiab nws tseem rhiab heev rau cov pa oxygen. Tus dityectric tas li thiab semiconductor cov yam ntxwv ntawm rutile titanium yog qhov tseem ceeb rau kev lag luam hluav taws xob, thiab cov khoom siv hluav taws xob zoo li cericic hluav taws xob.
5) Hardness
Raws li cov nplai ntawm Mohs Hardness, Rutile Titanium Dioxide yog 6-6.5, thiab Anatase Titanium Dioxide yog 5.5-6.0. Yog li ntawd, nyob rau hauv cov tshuaj fiber tuinction, lub anatase hom yog siv kom tsis txhob muaj kev hnav ntawm cov spinneret qhov.
6) Hygroscopicity
Txawm hais tias Titanium Dioxide yog hydrophilic, nws hydroscopicity tsis muaj zog heev, thiab hom rutile yog me dua li hom anatase. Lub hygroscopicity ntawm titanium dioxide muaj qee qhov kev sib raug zoo nrog qhov loj me ntawm nws thaj chaw. Thaj chaw loj thiab thaj chaw siab kuj tseem muaj feem xyuam rau kev kho mob saum npoo thiab cov khoom.
7) thermal stability
Titanium Dioxide yog cov khoom siv nrog kev ua haujlwm zoo thermal.
8) Granularity
Lub particle loj muab faib rau Titanium Dioxide yog cov ntsuas ntsuas qhov tseeb, uas cuam tshuam rau cov kev ua tau zoo ntawm Titanium Dioxide Pigments thiab cov khoom thov cov khoom thov kev kawm. Yog li ntawd, kev sib tham ntawm npog lub zog thiab dispersibility tuaj yeem raug txheeb xyuas ncaj qha los ntawm particle loj faib.
Qhov xwm txheej cuam tshuam rau cov particle loj faib ntawm titanium dioxide yog complex. Qhov thib ib yog qhov loj me ntawm thawj particle loj ntawm hydrolysis. Los ntawm kev tswj hwm thiab kho cov txheej txheem hydrolysis, tus thawj particle loj yog nyob rau hauv qee qhov ntau. Qhov thib ob yog lub xam kub. Thaum lub sij hawm redatitanic acid, cov hais uas dhau mus ua lub sijhawm sib hloov thiab lub sijhawm tsim nyog, thiab qhov ntsuas kub uas tsim nyog tau ua kom muaj kev loj hlob ntawm qee qhov ntau. Kauj ruam kawg yog lub pulverization ntawm cov khoom. Feem ntau, kev hloov kho ntawm cov raymond zeb thiab kev hloov kho ntawm tus analyzer ceev tau siv los tswj qhov pulliterization zoo. Nyob rau tib lub sijhawm, lwm cov khoom siv pulverizing tuaj yeem siv, xws li: High-ceev pulverizer, Dav hlau pulverizer thiab rauj mills.
