Ukuqonda Izinhlobo Ezihlukene ze-TiO2

I-Titanium dioxide, evame ukubizwa ngokuthi i-TiO2, i-pigment eguquguqukayo esetshenziswa ezimbonini ezahlukahlukene. Yaziwa ngezindawo zayo ezinhle kakhulu zokuhlakaza ukukhanya, inkomba ephezulu ye-refractive kanye nokuvikelwa kwe-UV. Nokho, akuwona wonke ama-TiO2 afanayo. Kunezinhlobo ezahlukene ze-TiO2, ngayinye enezici zayo ezihlukile kanye nezinhlelo zokusebenza. Kule bhulogi, sizohlola ezihlukahlukeneizinhlobo ze-TiO2kanye nokusetshenziswa kwazo okuqondile.

1. I-Rutile TiO2:

I-Rutile TiO2 yaziwa ngenkomba yayo ephezulu ye-refractive kanye nezakhiwo ezinhle kakhulu zokuvikela i-UV. Ivamise ukusetshenziswa kuma-sunscreens, amapende namapulasitiki ukuze kunikeze isivikelo se-UV esiphezulu futhi kuthuthukise ukuqina komkhiqizo.I-rutile titanium dioxideibuye ibaluleke ngombala wayo omhlophe ocwebezelayo futhi ivame ukusetshenziswa kumapende nasezimbotsheni ngenxa yokungafihli nokukhanya kwayo.

2. I-Anatase titanium dioxide:

 I-Anatase TiO2kungenye indlela evamile ye-TiO2, eyaziwa ngendawo yayo ephezulu kanye nezakhiwo ze-photocatalytic. Ngenxa yekhono layo lokubhidliza ukungcola okuphilayo ngaphansi kokukhanya kwe-UV, isetshenziswa kakhulu ekusetshenzisweni kwemvelo njengokuhlanza umoya namanzi. Ngenxa yezakhiwo zayo ze-photocatalytic, i-anatase titanium dioxide iphinde isetshenziswe ezimbotsheni zokuzihlanza namaseli e-photovoltaic.

3. I-Nano titanium dioxide:

I-Nano-TiO2 ibhekisela kuzinhlayiya ze-titanium dioxide ezinosayizi kububanzi be-nanometer. Lezi zinhlayiya ze-ultrafine zibonisa umsebenzi we-photocatalytic othuthukisiwe futhi zinezinhlobonhlobo zezinhlelo zokusebenza, ezihlanganisa izindawo ezizihlanzayo, amasistimu okuhlanza umoya, nezingubo zokulwa namagciwane. I-Nanoscale titanium dioxide nayo isetshenziswa embonini yezimonyo ngenxa yezakhiwo zayo ezihlakaza ukukhanya kanye nekhono lokuhlinzeka ngokuqedwa okubushelelezi, okuluhlaza emikhiqizweni yokunakekelwa kwesikhumba.

4. I-Ultra-fine TiO2:

I-Ultrafine titanium dioxide, eyaziwa nangokuthi i-submicron titanium dioxide, iqukethe izinhlayiya ezingaphansi kwe-micron eyodwa ngosayizi. Lolu hlobo lwe-TiO2 lubaluleke kakhulu endaweni yalo ephezulu, okuyenza ifanelekele izinhlelo zokusebenza ezidinga ukuhlakazeka okuhle kakhulu kanye nokufakwa, okufana noyinki, okokunamathela nezinamatheliso. I-Ultrafine titanium dioxide iphinde isetshenziswe ekukhiqizeni izitsha zobumba ezisebenza kahle kanye nama-catalysts.

Ngamafuphi, izinhlobo ezahlukene zetitanium dioxidebabe nezinhlobonhlobo zezakhiwo kanye nezicelo, okwenza kube izithako ezibalulekile ezimbonini ezihlukahlukene. Ukuthi isetshenziselwa ukuvikela i-UV, i-photocatalysis noma ukuthuthukisa izimfanelo zobuhle bomkhiqizo, ukuqonda izici ezithile zohlobo ngalunye lwe-TiO2 kubalulekile ekukhetheni into efanele yohlelo lokusebenza oluthile. Njengoba ubuchwepheshe buqhubeka nokuthuthuka, ukuthuthukiswa kwe-TiO2 entsha enezakhiwo ezithuthukisiwe kuzokwandisa ukusetshenziswa kwayo okunamandla kwesikhathi esizayo.
