I-Titanium dioxide(TiO2) i-pigment emhlophe esetshenziswa kabanzi ezimbonini ezahlukahlukene, kufaka phakathi amapende, ama-coatings, amapulasitiki nezimonyo. Itholakala ngezindlela ezimbili eziyinhloko zekristalu: i-anatase ne-rutile. Ukuqonda umehluko phakathi kwalezi zinhlobo ezimbili kubalulekile ekwandiseni ukusetshenziswa kwazo ezintweni ezahlukene.
I-Anatase TiO2 kanye ne-rutile TiO2 ibonisa umehluko osobala ekwakhekeni kwekristalu, izakhiwo nezinhlelo zokusebenza. Lo mehluko udlala indima ebalulekile ekunqumeni ukusebenza nokusebenza kwezinto eziqukethwe.
Isakhiwo sekristalu:
I-Anatase TiO2ine-tetragonal crystal structure, kuyilapho i-rutile TiO2 inesakhiwo esiminyene se-tetragonal. Ukwehluka kwezakhiwo zabo zekristalu kuholela ekuhlukeni kwezakhiwo zabo ezingokomzimba namakhemikhali.
Isici:
I-Anatase TiO2 yaziwa ngokusebenza kwayo kabusha okuphezulu kanye nezakhiwo ze-photocatalytic. Ivame ukusetshenziswa ezinhlelweni ezidinga i-photocatalysis, njengezingubo zokuzihlanza kanye nokulungiswa kwemvelo. Ngakolunye uhlangothi, i-rutile TiO2 inenkomba ephezulu yokugqamisa kanye nekhono elikhulu lokumunca i-UV, okuyenza ifanelekele ukuvikeleka kwe-UV ezikhiqizweni zelanga kanye nezingubo zokulwa ne-UV.
Isicelo:
Iumehluko phakathi kwe-anatase ne-rutile TiO2uzenze zilungele izinhlelo zokusebenza ezahlukene. I-Anatase TiO2 ivamise ukusetshenziswa emikhiqizweni edinga amazinga aphezulu omsebenzi we-photocatalytic, njengamasistimu okuhlanza umoya namanzi, kuyilapho i-rutile TiO2 ikhethwa ezinhlelweni ezidinga ukuvikelwa kwe-UV okuphakeme, njengezikhilimu zelanga, okokunamathisela kwangaphandle namapulasitiki.
Izinhlelo zokusebenza zokuqinisa:
Ukuqonda umehluko phakathi kwe-anatase ne-rutile TiO2 kuvumela abacwaningi nabakhiqizi ukuthi balungise ukwakheka kwezinto zabo zokusebenza ukuze bathuthukise ukusebenza. Ngokukhetha ifomu elifanele le-TiO2 elisuselwa kuzimfuneko ezithile zohlelo lokusebenza, bangathuthukisa ukusebenza nokusebenza kahle komkhiqizo wokugcina.
Isibonelo, emkhakheni wezingubo zokumboza, ukufakwa kwe-anatase titanium dioxide ezimbotsheni zokuzihlanza kungenza izindawo ezingaphezulu zimelane nokungcola nokungcola ngenxa yezakhiwo zayo ze-photocatalytic. Ngokuphambene, ukusebenzisa i-rutile titanium dioxide ezimbotsheni ezimelana ne-UV kukhulisa amandla ezinto ezibonakalayo okumelana nemisebe ye-UV, ngaleyo ndlela kunwebe impilo yendawo emboziwe.
Embonini yezimonyo, ukukhetha phakathi kwe-anatase nei-rutile TiO2kubalulekile ekwenzeni imithi yokuvikela ilanga enezinga elidingekayo lokuvikela i-UV. I-Rutile TiO2 inamandla amahle kakhulu okumunca i-UV futhi ngokuvamile iyinketho yokuqala yezivikeli zelanga eziklanyelwe ukunikeza amazinga aphezulu okuvikela kwe-UV.
Ngaphezu kwalokho, izici eziyingqayizivele ze-photocatalytic ze-anatase titanium dioxide zingase zisetshenziswe ukuze kuthuthukiswe ukucekelwa phansi kwezinto ezingcolile eziphilayo kanye nokuhlanzwa komoya namanzi lapho kwakhiwa izinto ezithuthukisiwe zokulungisa imvelo.
Sengiphetha, umehluko phakathi kwe-anatase TiO2 ne-rutile TiO2 udlala indima ebalulekile ekunqumeni ukufaneleka kwazo kwezinhlelo zokusebenza ezihlukahlukene. Ngokuqonda nokusebenzisa lo mehluko, abacwaningi nabakhiqizi bangakwazi ukuthuthukisa izakhiwo nokusebenza kwezinto ezibonakalayo, okuholela emikhiqizweni ethuthukisiwe enezakhiwo ezithuthukisiwe nokusebenza.
