Umhlaba Othakazelisayo We-Titanium Dioxide: Anatase, Rutile And Brookite

I-Titanium dioxide iyiminerali yemvelo esetshenziswa ezimbonini ezihlukahlukene, okuhlanganisa ukukhiqizwa kwamapende, amapulasitiki nezimonyo. Kunezinhlobo ezintathu eziyinhloko ze-titanium dioxide:i-anatase, i-rutile ne-brookite. Ifomu ngalinye linezindawo zalo ezihlukile kanye nezicelo, okulenza libe yizifundo ezithakaselekayo zokufunda.

I-Anatase ingenye yezinhlobo ezivame kakhulu ze-titanium dioxide. Yaziwa ngokusebenza kwayo kabusha okuphezulu futhi ivame ukusetshenziswa njenge-catalyst ekuphenduleni kwamakhemikhali. I-Anatase iphinde isetshenziswe njenge-pigment kumapende nama-coatings nasekukhiqizeni amaseli elanga. Isakhiwo sayo esiyingqayizivele se-crystal sinendawo ephezulu, okwenza kube yinto ekahle yokusetshenziswa kwe-catalytic.

I-Rutile ingenye indlela ye-titanium dioxide esetshenziswa kakhulu embonini. Yaziwa nge-high refractive index, ivame ukusetshenziswa njenge-pigment emhlophe kumapende, amapulasitiki, namaphepha. I-Rutile iphinde isetshenziswe njengesihlungi se-UV esikhumbeni selanga nakwezinye izimonyo ngenxa yezakhiwo zayo ezinhle kakhulu zokuvimbela i-UV. Inkomba yayo ephezulu ye-refractive iphinde ikwenze kube usizo ekukhiqizeni ama-lens optical kanye nengilazi.

I-Brookite iwuhlobo oluncane oluvamile lwe-titanium dioxide, kodwa iseyinto ebalulekile ngokwayo. Iyaziwa ngokusebenza kwayo okuphezulu kagesi futhi isetshenziselwa ukukhiqizwa kwezinto zikagesi ezifana namaseli elanga nezinzwa. I-Brookite iphinde isetshenziswe njenge-pigment emnyama kumapende namapende, futhi izakhiwo zayo eziyingqayizivele ziyenza ibe yinto ebalulekile yokusetshenziswa okuhlukahlukene.

Nakuba i-anatase, i-rutile, ne-brookite zonke kuyizinhlobo ze-titanium dioxide, ngayinye inezindawo zayo ezihlukile kanye nezicelo. Ukuqonda umehluko phakathi kwalawa mafomu kubalulekile ekusebenziseni kwawo ngempumelelo ezimbonini ezahlukahlukene. Kungakhathaliseki ukuthi isetshenziswa ekusetshenzisweni kwe-catalytic, njenge-pigment kupende, noma ezintweni zikagesi, uhlobo ngalunye lwe-titanium dioxide lunendima yalo.

Sengiphetha, umhlaba we-titanium dioxide uhluke kakhulu, futhi i-anatase, i-rutile ne-brookite zonke zinezakhiwo nezindlela zazo ezihlukile. Kusukela ekusetshenzisweni njengama-catalyst nama-pigments kuya endimeni yawo ezintweni zikagesi, lezi zinhlobo ze-titanium dioxide zidlala indima ebalulekile ezimbonini eziningi. Njengoba ukuqonda kwethu lezi zinsiza kuqhubeka kuthuthuka, singalindela ukusetshenziswa okusha kwe-anatase, rutile, ne-brookite eminyakeni ezayo.
