Titanium dioxide, feem ntau hu ua TiO2, yog ib qho kev sib xyaw ua ke uas tau nyiam cov neeg nyiam ntau vim nws cov khoom tshwj xeeb thiab ntau yam kev siv. Hauv blog no, peb yuav delve rau hauv cov khoom ntawm TiO2 thiab tshawb nrhiav nws cov ntawv thov sib txawv hauv ntau qhov kev lag luam.
Cov yam ntxwv ntawm titanium dioxide:
TiO2 yog ib txwm tshwm sim titanium oxide paub txog nws cov khoom tshwj xeeb. Ib qho ntawm nws cov khoom tseem ceeb tshaj plaws yog nws qhov siab refractive Performance index, uas ua rau nws zoo heev dawb pigment nyob rau hauv cov xim, coatings thiab plastics. Tsis tas li ntawd, titanium dioxide muaj kev tiv thaiv UV siab, ua rau nws muaj kev xaiv nrov rau cov tshuaj pleev thaiv hnub thiab UV thaiv cov ntaub ntawv. Nws cov xwm txheej tsis muaj tshuaj lom thiab tshuaj lom neeg ruaj khov ntxiv txhim kho nws qhov kev nyiam rau kev siv hauv cov khoom siv.
Lwm yam khoom tseem ceeb ntawmTiO 2yog nws cov haujlwm photocatalytic, tso cai rau nws ua rau cov tshuaj tiv thaiv tshuaj thaum raug lub teeb. Cov cuab yeej no tau pab txhawb kev txhim kho ntawm titanium dioxide-based photocatalysts rau kev kho ib puag ncig, dej huv, thiab kev tswj huab cua. Tsis tas li ntawd, TiO2 yog cov khoom siv hluav taws xob semiconductor uas muaj peev xwm siv hauv cov hnub ci hlwb thiab cov khoom siv photovoltaic vim nws muaj peev xwm nqus tau lub hnub ci zog thiab hloov mus rau hauv hluav taws xob hluav taws xob.
Kev siv ntawm titanium dioxide:
Cov khoom sib txawv ntawm TiO2 ua rau txoj hauv kev rau nws daim ntawv thov dav hauv ntau qhov kev lag luam. Hauv kev tsim kho, titanium dioxide yog siv los ua cov xim hauv cov xim, coatings thiab pob zeb ua kom cov xim dawb, opacity thiab durability. Nws cov UV kuj tseem ua rau nws zoo tagnrho rau kev siv sab nraum zoov xws li architectural coatings thiab cov khoom siv hauv tsev.
Hauv cov tshuaj pleev ib ce thiab cov khoom siv tu tus kheej, titanium dioxide yog cov khoom siv hauv cov tshuaj pleev thaiv hnub, tshuaj pleev thiab cov khoom siv tawv nqaij vim nws muaj peev xwm muab kev tiv thaiv UV zoo. Nws cov khoom tsis muaj tshuaj lom thiab hypoallergenic ua rau nws tsim nyog siv rau hauv cov txheej txheem ntawm daim tawv nqaij rhiab heev, ua rau nws muaj kev xaiv nrov ntawm cov neeg siv khoom.
Tsis tas li ntawd, titanium dioxide yog dav siv nyob rau hauv cov zaub mov thiab tshuaj industries li zaub mov xim, xim dawb nyob rau hauv cov ntsiav tshuaj thiab tsiav tshuaj. Nws inertness thiab non-reactivity xyuas kom meej nws muaj kev ruaj ntseg rau kev siv nyob rau hauv cov neeg siv khoom, thaum nws siab opacity thiab brightness txhim khu kev pom kev pom ntawm cov zaub mov thiab tshuaj formulations.
Tsis tas li ntawd, cov khoom siv photocatalytic ntawm titanium dioxide tau coj mus rau nws cov ntawv thov hauv ib puag ncig thiab kev siv hluav taws xob ntsig txog thev naus laus zis. TiO2-raws li photocatalysts yog siv rau huab cua thiab dej purification, pa phem degradation, thiab hydrogen ntau lawm los ntawm photocatalytic dej splitting. Cov ntawv thov no tuav cov lus cog tseg ntawm kev daws teeb meem ib puag ncig thiab txhawb nqa kev daws teeb meem hluav taws xob ruaj khov.
Muab ua ke, tio2 cov khoom thiab cov ntawv thov qhia txog nws qhov tseem ceeb hauv kev lag luam xws li kev tsim kho thiab tshuaj pleev ib ce rau kev kho ib puag ncig thiab kev siv hluav taws xob. Raws li kev tshawb fawb thiab kev tsim kho tshiab txuas ntxiv nthuav kev nkag siab ntawm TiO2, nws lub peev xwm rau cov ntawv thov tshiab yuav ntxiv cov ntaub ntawv kev tshawb fawb thiab kev siv thev naus laus zis.
