Titanium dioxide, feem ntau hu ua TiO2, yog ntau yam xim siv nyob rau hauv ntau yam lag luam. Nws yog lub npe hu rau nws zoo heev lub teeb tawg zog, siab refractive index thiab tiv thaiv UV. Muaj ntau hom TiO2, txhua tus muaj cov khoom tshwj xeeb thiab kev siv. Hauv blog no, peb yuav tshawb txog ntau hom titanium dioxide thiab lawv siv hauv kev lag luam sib txawv.
1. Rutile TiO2:
Rutile titanium dioxideyog ib qho ntawm feem ntau siv cov ntaub ntawv ntawm titanium dioxide. Nws yog lub npe hu rau nws qhov siab refractive index, uas ua rau nws zoo tagnrho rau cov ntawv thov uas yuav tsum tau muaj siab opacity thiab brightness. Rutile titanium dioxide yog dav siv nyob rau hauv zus tau tej cov xim, coatings, yas thiab ntawv, thiab nws zoo heev lub teeb tawg zog yuav ua rau kom lub whiteness thiab brightness ntawm cov khoom kawg.
2. Anatase titanium dioxide:
Anatase titanium dioxide yog lwm daim ntawv tseem ceeb ntawm titanium dioxide. Nws yog tus cwj pwm los ntawm qhov chaw siab tshaj plaws thiab cov khoom siv photocatalytic. Anatase TiO2 feem ntau yog siv rau hauv kev tsim cov txheej txheem photocatalytic, ntxuav tus kheej qhov chaw thiab kev siv tshuaj kho ib puag ncig. Nws lub peev xwm los catalyze lub decomposition ntawm cov organic tebchaw nyob rau hauv UV teeb ua rau nws yog ib qho tseem ceeb khoom rau huab cua thiab dej purification systems.
3. Nano titanium dioxide:
Nano-TiO2, tseem hu ua nanoscale titanium dioxide, yog ib hom TiO2 nrog ib tug particle loj nyob rau hauv lub nanometer ntau. Daim ntawv ultrafine ntawm TiO2 no tau txhim kho cov haujlwm photocatalytic, thaj chaw siab thiab txhim kho lub teeb tawg. Nanoscale titanium dioxide muaj ntau yam kev siv, suav nrog cov tshuaj pleev thaiv hnub, tshuaj pleev ib ce, txheej txheej tus phooj ywg thiab cov khoom siv tshuaj tua kab mob. Nws qhov me me me me muab kev tiv thaiv zoo dua thiab kev tiv thaiv hauv cov tshuaj pleev thaiv hnub thiab UV-thaiv txheej.
4. Coated titanium dioxide:
Txheej TiO2 yog hais txog txheej txheej titanium dioxide nrog cov khoom siv tsis zoo lossis cov organic los txhim kho lawv cov kev tawg, kev ruaj ntseg thiab kev sib raug zoo nrog cov matrices sib txawv. Coated TiO2 feem ntau yog siv rau hauv kev tsim cov txheej txheem ua haujlwm siab, inks thiab plastics, qhov chaw tsis sib xws ntawm TiO2 hais yog qhov tseem ceeb rau kev ua tiav cov khoom xav tau xws li kav ntev, huab cua tsis kam thiab xim stability.
Hauv cov ntsiab lus, txawvhom TiO2muaj ntau yam khoom thiab kev siv thoob plaws hauv kev lag luam. Los ntawm kev txhim kho cov xim dawb ntawm cov xim thiab cov txheej txheem los muab kev tiv thaiv UV hauv cov tshuaj pleev thaiv hnub los txhim kho huab cua thiab dej zoo los ntawm photocatalysis, titanium dioxide plays lub luag haujlwm tseem ceeb hauv ntau yam khoom thiab thev naus laus zis. Raws li kev tshawb fawb nanotechnology thiab kev txhim kho txuas ntxiv mus, peb tuaj yeem cia siab tias yuav pom kev tsim kho tshiab ntxiv thiab kev siv rau titanium dioxide yav tom ntej.
