Titanium dioxide yog ib qho tseem ceeb inorganic compound. Nws tau yeej lub koob npe nrov ntawm "qhov zoo tshaj plaws dawb pigment nyob rau hauv lub ntiaj teb no" rau nws cov tsis muaj toxicity, pom opacity, pom whiteness thiab brightness. Yog li, dab tsi yog qhov tseem ceeb ntawm titanium dioxide? Cia peb nthuav tawm nws qhov tsis meej ua ke.
1. Titanium dioxide yog siv rau hauv txheej
Hauv kev lag luam coatings, titanium dioxide tuaj yeem hais tias ci ntsa iab. Seb nws yog architectural coatings, automotive coatings los yog rooj tog coatings, nws yog inseparable ntawm nws muaj. Titanium dioxide tsis tsuas yog muab lub zog zais, ua rau cov txheej txheej smoother thiab muag heev, tab sis kuj txhim kho lub cev thiab tshuaj lom neeg ntawm cov txheej, xws li tshuaj lom neeg ruaj khov, corrosion kuj, lub teeb tsis kam thiab huab cua tsis kam. Tsis tas li ntawd, nws tuaj yeem tiv thaiv kev nkag mus ntawm ultraviolet rays thiab ya raws, yog li ncua kev laus ntawm txheej thiab txuas nws lub neej kev pab cuam. Nyob rau hauv lub tshav pob ntawm architectural txheej, kev noj ntawm titanium dioxide yog tshwj xeeb tshaj yog loj, uas muab cov vaj tse muaj zog thiab zoo nkauj lub tsho tiv no.
2. Titanium dioxide yog siv hauv papermaking
Kev lag luam papermaking kuj yog ib qho tseem ceeb ntawm daim ntawv thov ntawm titanium dioxide. Raws li kev muab tub lim, titanium dioxide tuaj yeem txhim kho cov xim dawb thiab ci ntawm daim ntawv, ua kom pom kev zoo nkauj dua. Nyob rau tib lub sijhawm, nws tseem tuaj yeem txhim kho cov neeg kho tshuab lub zog thiab ua haujlwm ntev ntawm cov ntawv thiab txhim kho cov khoom luam tawm zoo. Nws muaj lub zog zais zoo thiab huab cua tiv thaiv, thiab tuaj yeem siv rau xim thiab tiv thaiv cov ntaub ntawv xws li xim, yas, thiab roj hmab.
3. Titanium dioxide rau pleev
Hauv kev lag luam tshuaj pleev ib ce, titanium dioxide kuj ua lub luag haujlwm tseem ceeb. Nyob rau hauv cov tshuaj pleev ib ce xws li lub hauv paus, mem pleev di ncauj, thiab qhov muag ntxoov ntxoo, titanium dioxide ua raws li ib tug softener thiab whitening neeg sawv cev los txhim kho lub zais hwj chim thiab xim brightness ntawm cov khoom. Qhov tseem ceeb tshaj, nws tseem tuaj yeem siv los ua cov tshuaj pleev thaiv hnub tseem ceeb kom nqus tau cov kab hluav taws xob ultraviolet, tiv thaiv cov teeb meem ultraviolet rays, thiab tiv thaiv daim tawv nqaij los ntawm kev puas tsuaj.
4. Titanium dioxide rau tu
Titanium dioxide kuj tau pom muaj peev xwm ua tau zoo hauv kev tu thiab kho dej phwj tuaj. Raws li photocatalyst, nws tuaj yeem ua kom oxidation lossis txo cov pa phem ntau yam xws li ozone, sulfur dioxide, thiab nitrogen oxides nyob rau hauv qhov kev txiav txim ntawm lub teeb, ua rau huab cua huv. Hauv kev kho dej phwj tuaj, titanium dioxide tuaj yeem pab txhim kho kev kho cov dej khib nyiab thiab tiv thaiv peb cov dej.
5. Titanium dioxide yog siv rau hauv cov khoom siv hluav taws xob
Titanium dioxide kuj muaj cov khoom siv hluav taws xob zoo thiab siv dav hauv kev npaj cov khoom siv optoelectronic. Piv txwv li, nws tuaj yeem siv los tsim cov hnub ci hnub ci, photocatalytic electrodes, thiab lwm yam los hloov lub teeb lub zog rau hauv hluav taws xob hluav taws xob lossis catalyze tshuaj lom neeg. Hauv kev ua haujlwm ntawm lub zog, titanium dioxide muaj peev xwm siv tau zoo thiab xav tias yuav muab cov kev daws teeb meem tshiab rau kev txhim kho thiab kev siv lub zog tauj dua tshiab.
6. Titanium dioxide cov neeg siv tshuaj
Titanium dioxide kuj tau siv dav hauv kev kho mob. Nws muaj cov biocompatibility zoo thiab cov khoom siv tshuaj tua kab mob thiab tuaj yeem siv los npaj cov ntaub ntawv kho mob thiab cov neeg nqa tshuaj. Tib lub sijhawm, titanium dioxide kuj tuaj yeem siv rau kev tua kab mob ntawm cov cuab yeej kho mob thiab kev ua kom huv ntawm huab cua los ntawm photocatalytic sterilization. Kev thov ntawm titanium dioxide yog ntau tshaj qhov ntawd. Nws cov tshuaj lom neeg ruaj khov siab, cov khoom siv hluav taws xob semiconductor thiab cov haujlwm photocatalytic ua rau nws muaj txiaj ntsig zoo hauv ntau qhov chaw.
Hauv cov ntsiab lus, titanium dioxide, uas yog ib qho tseem ceeb ntawm cov khoom siv tsis zoo, muaj ntau yam kev siv hauv kev lag luam, kev tiv thaiv ib puag ncig, lub zog thiab tshuaj. Nws cov khoom tshwj xeeb thiab ntau yam ua rau titanium dioxide yog ib yam khoom tseem ceeb hauv ntau qhov chaw. Nrog nws cov khoom tshwj xeeb, nws tau coj ntau yam yooj yim thiab kev zoo nkauj rau tib neeg lub neej. Nyob rau hauv lub neej yav tom ntej, nrog rau kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis thiab kev tsim kho kev lag luam, thaj chaw thov ntawm titanium dioxide yuav txuas ntxiv nthuav dav thiab tsim kom muaj txiaj ntsig ntau rau noob neej.
