Titanium dioxide

Titanium dioxide (TiO2) ke pigment e tšoeu e sebelisoang haholo liindastering tse fapaneng ka lebaka la thepa ea eona e ikhethang. Mona ke kakaretso ea titanium dioxide, thepa ea eona, le lits'ebetso tsa eona tse fapaneng:

1. Sebopeho sa Lik'hemik'hale: Titanium dioxide ke oxide ea tlhaho ea titanium e nang le foromo ea lik'hemik'hale ea TiO2. E fumaneha ka mefuta e mengata ea kristale, 'me rutile le anatase ke tsona tse tloaelehileng haholo. Rutile TiO2 e tsebahala ka index ea eona e phahameng ea refractive le opacity, ha anatase TiO2 e bonts'a ts'ebetso e phahameng ea photocatalytic.
2. White Pigment: E 'ngoe ea lintho tse ka sehloohong tseo titanium dioxide e li sebelisang ke ho etsa 'mala o mosoeu lipenteng, lirapeng, lipolasetiking le pampiring. E fana ka khanya, opacity, le bosoeu ho lisebelisoa tsena, ho etsa hore li khahlehe le ho matlafatsa tšireletso ea tsona le matla a ho pata. Titanium dioxide e ratoa ho feta mebala e meng e tšoeu ka lebaka la litšobotsi tsa eona tse ntle tsa ho hasanya khanya le ho hana ho fetoha ha mebala.
3. UV Absorber le Sunscreen: Titanium dioxide e sebelisoa haholo e le ntho e monyang mahlaseli a kotsi a letsatsi le lihlahisoa tsa litlolo. E sebetsa e le setlolo se sireletsang letlalo letsatsing ka ho bonahatsa le ho hasanya mahlaseli a UV, kahoo e sireletsa letlalo liphellong tse kotsi tse kang ho chesoa ke letsatsi, ho tsofala pele ho nako le kankere ea letlalo. Likaroloana tsa nanoscale titanium dioxide hangata li sebelisoa ho etsa litlolo tse sireletsang letsatsi bakeng sa ho pepeseha ha tsona le tšireletso ea UV e pharalletseng.
4. Photocatalyst: Mefuta e meng ea titanium dioxide, haholo-holo anatase TiO2, e bonts'a ts'ebetso ea photocatalytic ha e pepesehetse leseli la ultraviolet. Thepa ena e etsa hore titanium dioxide e khone ho susumetsa liphetoho tse fapaneng tsa lik'hemik'hale, tse kang ho bola ha lintho tse silafatsang tsa lintho tse phelang le ho hloekisoa ha bokaholimo. Photocatalytic titanium dioxide e sebelisoa liphahlong tsa ho itlhoekisa, lits'ebetso tsa tlhoekiso ea moea, le lits'ebetsong tsa ho hloekisa metsi.
5. Keketso ea Lijo: Titanium dioxide e amohetsoe e le tlatsetso ea lijo (E171) ke mekhatlo ea taolo e kang FDA le European Food Safety Authority (EFSA). Hangata e sebelisoa lihlahisoa tsa lijo, tse kang confectionery, thepa e halikiloeng, le lihlahisoa tsa lebese, e le ntho e soeufatsang le opacifier. Titanium dioxide e thusa ho ntlafatsa ponahalo le sebōpeho sa lijo, ho etsa hore li khahle bareki haholoanyane.
6. Tšehetso ea Catalyst: Titanium dioxide e sebetsa e le ts'ehetso ea ts'ehetso lits'ebetsong tse fapaneng tsa lik'hemik'hale, ho kenyelletsa le ho lokisa lintho tse fapaneng le ho lokisoa ha tikoloho. E fana ka sebaka se phahameng le sebopeho se tsitsitseng sa ts'ehetso bakeng sa libaka tse sebetsang tsa catalytic, e thusa ho sebetsana le lik'hemik'hale tse sebetsang hantle le ho senyeha ha litšila. Li-catalyst tse tšehelitsoeng ke Titanium dioxide li sebelisoa lits'ebetsong tse joalo ka kalafo ea mosi oa likoloi, tlhahiso ea haedrojene, le ho hloekisa metsi a litšila.
7. Electroceramics: Titanium dioxide e sebelisoa ha ho etsoa lisebelisoa tsa motlakase, tse kang li-capacitor, varistors, le li-sensor, ka lebaka la thepa ea eona ea dielectric le semiconductor. E sebetsa e le thepa ea dielectric e phahameng ea k ho li-capacitor, e nolofalletsang ho boloka matla a motlakase, hape e le thepa e sa utloeng bohloko ka khase ho li-sensor bakeng sa ho lemoha likhase le metsoako ea lintho tse phelang.

Ka kakaretso, titanium dioxide ke sesebelisoa se feto-fetohang se nang le lits'ebetso tse ngata tse fapaneng, ho kenyeletsoa joalo ka pigment e tšoeu, mohanyi oa UV, photocatalyst, tlatsetso ea lijo, tšehetso ea li-catalyst, le karolo ea electroceramic. Motsoako oa eona o ikhethang oa thepa o e etsa hore e be ea bohlokoa haholo indastering e kang lipente le litlolo, litlolo, tokiso ea tikoloho, lijo, lisebelisoa tsa elektroniki le tlhokomelo ea bophelo bo botle.
