I-Titanium Dioxide

I-Titanium dioxide (TiO2) i-pigment emhlophe esetshenziswa kakhulu ezimbonini ezihlukahlukene ngenxa yezakhiwo zayo eziyingqayizivele.Nakhu ukubuka konke kwe-titanium dioxide, izici zayo, kanye nezinhlelo zayo ezihlukahlukene:

1. Ukubunjwa Kwamakhemikhali: I-Titanium dioxide iyi-oxide eyenzeka ngokwemvelo ye-titanium enefomula yamakhemikhali i-TiO2.Itholakala ngezindlela eziningana zekristalu, kanti i-rutile ne-anatase yizona ezivame kakhulu.I-Rutile TiO2 yaziwa ngenkomba yayo ephezulu ye-refractive ne-opacity, kuyilapho i-anatase TiO2 ibonisa umsebenzi ophakeme we-photocatalytic.
2. I-White Pigment: Enye yezindlela eziyinhloko ezisetshenziswa ngayo i-titanium dioxide ifana ne-pigment emhlophe kumapende, ezimbotsheni, kumapulasitiki, nasephepheni.Inikeza ukukhanya, ukukhanya, nokumhlophe kulezi zinto, izenze zikhange futhi zithuthukise ukumboza kwazo namandla okufihla.I-Titanium dioxide ikhethwa ngaphezu kwezinye izibala ezimhlophe ngenxa yezakhiwo zayo ezinhle kakhulu zokuhlakaza ukukhanya kanye nokumelana nokuguquguquka.
3. I-UV Absorber ne-Sunscreen: I-Titanium dioxide isetshenziswa kabanzi njengesimunyisi se-UV ezikhiqizweni zelanga nemikhiqizo yezimonyo.Isebenza njengesivikelo elangeni esingokomzimba ngokubonisa futhi isakaze imisebe ye-UV, ngaleyo ndlela ivikele isikhumba emiphumeleni eyingozi njengokushiswa yilanga, ukuguga ngaphambi kwesikhathi, nomdlavuza wesikhumba.Izinhlayiya ze-Nanoscale titanium dioxide zivame ukusetshenziswa ekwakhiweni kwesikrini selanga ukuze zibe sobala kanye nokuvikela okubanzi kwe-UV.
4. I-Photocatalyst: Izinhlobo ezithile ze-titanium dioxide, ikakhulukazi i-anatase TiO2, zibonisa umsebenzi we-photocatalytic lapho zivezwe ekukhanyeni kwe-ultraviolet.Lesi sakhiwo senza i-titanium dioxide ikwazi ukuvuselela ukusabela kwamakhemikhali okuhlukahlukene, njengokubola kokungcola kwemvelo kanye nokuvalwa kwezindawo ezingaphezulu.I-Photocatalytic titanium dioxide isetshenziswa ezimbotsheni zokuzihlanza, izinhlelo zokuhlanza umoya, nasezinhlelweni zokuhlanza amanzi.
5. Isengezo Sokudla: I-Titanium dioxide igunyazwe njengesengezo sokudla (E171) ngama-ejensi alawulayo afana ne-FDA kanye ne-European Food Safety Authority (EFSA).Ivame ukusetshenziswa emikhiqizweni yokudla, efana ne-confectionery, izimpahla ezibhakiwe, nemikhiqizo yobisi, njenge-ejenti emhlophe kanye ne-opacifier.I-Titanium dioxide isiza ukuthuthukisa ukubukeka nokuthungwa kwezinto zokudla, izenze zikhange nakakhulu kubathengi.
6. Ukusekelwa Kwe-Catalyst: I-Titanium dioxide isebenza njengesisusa sezinqubo ezihlukahlukene zamakhemikhali, okuhlanganisa i-catalysis ehlukahlukene kanye nokulungiswa kwemvelo.Ihlinzeka ngendawo ephezulu kanye nesakhiwo sokusekela esizinzile sezindawo ezisebenzayo, yenza kube lula ukusabela okusebenzayo kwamakhemikhali kanye nokucekelwa phansi okungcolisayo.Ama-catalyst asekelwa i-Titanium dioxide asetshenziswa ezinhlelweni ezifana nokukhishwa kwe-exhaust yezimoto, ukukhiqizwa kwe-hydrogen, nokuhlanza amanzi angcolile.
7. I-Electroceramics: I-Titanium dioxide isetshenziswa ekukhiqizeni izinto zikagesi zikagesi, njengama-capacitor, ama-varistors, nezinzwa, ngenxa yezakhiwo zayo ze-dielectric kanye ne-semiconductor.Isebenza njenge-high-k dielectric material kuma-capacitor, evumela ukugcinwa kwamandla kagesi, futhi njengento ezwela igesi kuzinzwa zokuthola amagesi kanye nezinhlanganisela eziphilayo eziguquguqukayo.

Kafushane, i-titanium dioxide iyinto eguquguqukayo enezinhlobonhlobo zezinhlelo zokusebenza, kufaka phakathi i-pigment emhlophe, i-UV absorber, i-photocatalyst, isithasiselo sokudla, ukusekelwa kwe-catalyst, kanye nengxenye ye-electroceramic.Inhlanganisela yayo eyingqayizivele yezakhiwo iyenza ibaluleke kakhulu ezimbonini ezinjengamapende nama-coatings, izimonyo, ukulungiswa kwemvelo, ukudla, izinto zikagesi, nokunakekelwa kwezempilo.
