Dab tsi yog titanium dioxide?

Titanium dioxide (TiO2) yog ib qho tshwm sim oxide ntawm titanium thiab ib qho ntawm cov xim dawb thiab ntau yam siv hauv ntau yam lag luam. Nws tshwm sim nyob rau hauv cov zaub mov thiab muaj ntau hom, nrog rau rutile, anatase, thiab brookite, nrog rutile thiab anatase yog cov feem ntau siv.

Cov yam ntxwv tseem ceeb thiab kev siv ntawm titanium dioxide muaj xws li:

Tus neeg sawv cev dawb:Nws tau dav siv los ua cov xim dawb vim nws qhov zoo tshaj plaws lub teeb-scattering zog, opacity, thiab brightness. Nws muab cov xim dawb thiab ci ntsa iab rau cov khoom xws li xim, txheej, yas, ntawv, tshuaj pleev ib ce, thiab khoom noj.

UV Absorbent:Titanium dioxide muaj UV thaiv cov khoom, ua rau nws muaj txiaj ntsig zoo hauv cov tshuaj pleev thaiv hnub thiab lwm yam khoom siv tawv nqaij. Nws pab tiv thaiv daim tawv nqaij los ntawm absorbing thiab scattering UV rays.

Catalyst:Qee cov ntaub ntawv ntawm titanium dioxide, tshwj xeeb tshaj yog daim ntawv anatase, nthuav tawm cov khoom photocatalytic. Qhov no ua rau lawv muaj txiaj ntsig zoo li catalysts nyob rau hauv ntau yam kev siv ib puag ncig, xws li huab cua purification, dej kho, thiab kev tu tus kheej. Thaum raug lub teeb, titanium dioxide tuaj yeem pib cov tshuaj tiv thaiv uas ua rau cov pa phem thiab tua cov kab mob.

Coatings thiab Inks:Nws yog siv nyob rau hauv zus tau tej cov coatings, inks, thiab yas los impart opacity, brightness, thiab durability.

Khoom noj khoom haus Additive:Titanium dioxide, thaum nyob rau hauv cov zaub mov-qib daim ntawv, yog siv los ua khoom noj khoom haus additives, feem ntau yog xim dawb los txhim kho cov tsos ntawm tej yam khoom noj xws li confectionery, sauces, thiab cov khoom noj siv mis.

Txawm hais tias nws siv dav, muaj kev sib tham txog kev nyab xeeb ntawm nanoparticles ntawm titanium dioxide hauv qee hom, tshwj xeeb tshaj yog hais txog kev nqus pa thiab nqus tau. Cov koom haum tswj hwm hauv ntau lub tebchaws tau teeb tsa cov kev txwv thiab cov lus qhia rau nws siv hauv cov khoom noj thiab tshuaj pleev ib ce kom muaj kev nyab xeeb.

Zuag qhia tag nrho, titanium dioxide ntau yam, ci ntsa iab, thiab ntau yam khoom muaj txiaj ntsig ua rau nws muaj txiaj ntsig thiab siv dav hauv ntau qhov kev lag luam.
