Nkag siab txog ntau hom TiO2

Titanium dioxide, feem ntau hu ua TiO2, yog ntau yam xim siv nyob rau hauv ntau yam kev lag luam. Nws yog lub npe hu rau nws zoo heev lub teeb tawg zog, siab refractive index thiab tiv thaiv UV. Txawm li cas los xij, tsis yog txhua tus TiO2 zoo ib yam. Muaj ntau hom TiO2, txhua tus muaj nws tus kheej cov khoom thiab kev siv. Hauv blog no, peb yuav tshawb txog ntau yamhom TiO2thiab lawv cov kev siv tshwj xeeb.

1. Rutile TiO2:

Rutile TiO2 paub txog nws qhov siab refractive index thiab zoo heev UV tiv thaiv cov khoom. Nws yog feem ntau siv rau hauv cov tshuaj pleev thaiv hnub, pleev xim thiab cov yas los muab kev tiv thaiv UV zoo tshaj thiab txhim kho cov khoom ruaj khov.Rutile titanium dioxidetseem muaj nuj nqis rau nws cov xim dawb ci ntsa iab thiab feem ntau yog siv rau hauv cov xim thiab cov txheej txheem rau nws cov opacity thiab brightness.

2. Anatase titanium dioxide:

 Anatase TiO2yog lwm hom TiO2, paub txog nws thaj chaw siab thiab cov khoom photocatalytic. Vim nws lub peev xwm los rhuav tshem cov pa phem hauv qab UV teeb, nws tau siv dav hauv kev siv ib puag ncig xws li huab cua thiab dej huv. Vim nws cov khoom siv photocatalytic, anatase titanium dioxide kuj tseem siv rau hauv cov txheej txheem ntxuav tus kheej thiab cov cell photovoltaic.

3. Nano titanium dioxide:

Nano-TiO2 hais txog titanium dioxide hais nrog qhov ntau thiab tsawg hauv nanometer ntau yam. Cov khoom siv ultrafine no nthuav tawm cov kev ua haujlwm zoo photocatalytic thiab muaj ntau yam kev siv, nrog rau kev ntxuav tus kheej, cua purification systems, thiab antimicrobial coatings. Nanoscale titanium dioxide kuj tseem siv rau hauv kev lag luam tshuaj pleev ib ce rau nws lub teeb-scattering zog thiab muaj peev xwm muab ib tug du, matte tiav rau cov khoom tu tawv nqaij.

4. Ultra-nplua TiO2:

Ultrafine titanium dioxide, tseem hu ua submicron titanium dioxide, muaj cov khoom tsawg dua ib micron loj. Hom TiO2 no muaj nuj nqis rau nws qhov chaw siab, uas ua rau nws tsim nyog rau cov ntawv thov uas yuav tsum tau muaj kev cuam tshuam zoo thiab kev pab cuam, xws li inks, coatings thiab adhesives. Ultrafine titanium dioxide kuj tseem siv rau hauv kev tsim cov ceramics thiab catalysts.

Hauv kev xaus, ntau homtitanium dioxidemuaj ntau yam khoom thiab kev siv, ua rau lawv cov khoom xyaw tseem ceeb hauv ntau yam kev lag luam. Txawm hais tias siv los tiv thaiv UV, photocatalysis lossis txhim kho qhov zoo nkauj ntawm cov khoom, kev nkag siab txog cov khoom tshwj xeeb ntawm txhua hom TiO2 yog qhov tseem ceeb rau kev xaiv cov khoom siv rau ib daim ntawv thov tshwj xeeb. Raws li kev siv thev naus laus zis txuas ntxiv mus, kev txhim kho ntawm TiO2 tshiab nrog cov khoom txhim kho ntxiv yuav nthuav dav nws txoj kev siv yav tom ntej.
