Kev siv cov yam ntxwv ntawm titanium dioxide
Apr 18, 2023
Titanium dioxide yog ib qho tseem ceeb ntawm cov xim dawb thiab glaze rau cov plooj (porcelain). Siv rau hauv cov xim, inks, yas, roj hmab, ntawv ua, tshuaj fiber ntau, xim xim dej thiab lwm yam lag luam.
Titanium dioxide yog cov khoom dawb tshaj plaws hauv ntiaj teb. Ib gram ntawm titanium dioxide tuaj yeem tig thaj tsam ntawm ntau tshaj 450 square centimeters dawb. Nws yog 5 npaug ntau dua li cov xim dawb li niaj zaus - lithopone, yog li nws yog cov xim zoo tshaj plaws rau cov xim dawb. Titanium dioxide siv los ua cov xim hauv ntiaj teb muaj 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 muab ntxiv rau daim ntawv nyiaj thiab daim duab kos duab.
titanium dioxide qee zaum ntxiv rau cov xim ntawm cov yas thiab soften lub ci ntawm viscose.
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 semiconducting titanium dioxide tau tso cai siv rau hauv ntau qhov chaw, xws li huab cua, dej thiab kua purification. 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 hauv tsev pavements, paving slabs, pob zeb phab ntsa lossis cov vuas, lawv tuaj yeem ua rau kom cov pa phem xws li nitrogen oxides, aromatics thiab aldehydes.
Tsis tas li ntawd, nws kuj tau siv dav hauv kev tsim cov tshuaj pleev thaiv hnub, uas tsis muaj tshuaj lom thiab tsis muaj mob rau tib neeg lub cev.
Ultra-nplua titanium dioxide muaj kev tiv thaiv UV zoo thiab pob tshab. Nws yog dav siv nyob rau hauv cov tshuaj pleev ib ce, ntoo preservatives, zaub mov ntim plastics, ruaj hauv tsev films, dag thiab ntuj fibers, thiab clear coatings. Cov nyhuv tshwj xeeb kho qhov muag hauv cov hlau flash txheej ua rau nws muaj txiaj ntsig thiab siv rau hauv cov xim zoo nkauj.
