Kev siv cov yam ntxwv ntawm titanium dioxide
Apr 18, 2023
Titanium dioxide yog ib qho tseem ceeb xim dawb thiab porcelain glaze. Siv rau hauv cov xim, number case, yas, roj hmab, papermaking, chemical fiber, watercolor pigment thiab lwm yam lag luam.
Titanium dioxide yog qhov dawb tshaj plaws hauv ntiaj teb. Ib gram ntawm titanium dioxide tuaj yeem pleev xim rau thaj tsam ntawm ntau dua 450 square centimeters dawb. Nws yog 5 npaug ntawm cov xim dawb dua li cov xim dawb - lithopone, yog li nws yog cov xim zoo tshaj plaws rau cov xim dawb. Titanium dioxide siv los ua cov xim hauv ntiaj teb yog ntau tshaj li pua txhiab tons hauv ib xyoos. Titanium dioxide tuaj yeem muab ntxiv rau hauv daim ntawv kom cov ntawv dawb thiab opaque. Cov nyhuv yog 10 npaug ntau dua li ntawm lwm yam tshuaj. Yog li ntawd, titanium dioxide yuav tsum tau ntxiv rau daim ntawv banknote thiab daim duab kos duab.
Txhawm rau ua kom cov xim ntawm cov yas thiab soften lub luster ntawm rayon, titanium dioxide qee zaum ntxiv.
Hauv kev lag luam roj hmab, titanium dioxide kuj yog siv los ua cov roj hmab dawb.
Cov khoom siv hluav taws xob photochemical ntawm semiconductor titanium dioxide tau ua rau nws siv tau rau ntau qhov chaw, xws li huab cua, dej thiab kua dej huv. Photocatalysts doped nrog carbon lossis lwm yam heteroatoms kuj tuaj yeem siv rau hauv qhov chaw kaw lossis thaj chaw uas muaj cov teeb ci tawg. Thaum siv cov coatings ntawm cov tsev, cov slabs, cov phab ntsa pob zeb lossis cov vuas vov tsev, lawv tuaj yeem ua rau cov pa phem xws li nitrogen oxides, aromatics thiab aldehydes.
Tsis tas li ntawd, nws kuj tau siv dav hauv kev tsim tshuaj pleev thaiv hnub, tsis muaj tshuaj lom thiab tsis muaj mob rau tib neeg lub cev.
Ultrafine titanium dioxide muaj UV tiv thaiv zoo thiab pob tshab. Nws yog dav siv nyob rau hauv cov tshuaj pleev ib ce, tiv thaiv ntoo, khoom noj khoom haus ntim yas, ruaj tsev neeg films, neeg tsim thiab ntuj fibers, pob tshab coatings. Qhov tshwj xeeb optical nyhuv nyob rau hauv hlau flash txheej ua rau nws muaj nuj nqis thiab siv nyob rau hauv high-qib xim tsheb.
