I-Titanium dioxide, ngokuvamile eyaziwa ngokuthi i-TiO2, iyinhlanganisela esebenza ngezindlela eziningi eye yadonsa ukunakwa okusabalele ngenxa yezakhiwo zayo eziyingqayizivele kanye nohlu olubanzi lwezinhlelo zokusebenza. Kule bhulogi, sizocubungula izici ze-TiO2 futhi sihlole ukusetshenziswa kwayo okuhlukahlukene ezimbonini ezahlukahlukene.
Izici ze-titanium dioxide:
I-TiO2 iyi-titanium oxide eyenzeka ngokwemvelo eyaziwa ngezici zayo ezingavamile. Enye yezindawo zayo eziphawuleka kakhulu inkomba yayo ephezulu ye-refractive, eyenza ibe nemibala emihle kakhulu emhlophe kumapende, okokunamathela namapulasitiki. Ukwengeza, i-titanium dioxide inokumelana okuphezulu kwe-UV, okuyenza ibe yisinqumo esidumile sokuvikela ilanga nezinto ezivimbela i-UV. Imvelo yayo engenabo ubuthi kanye nokuzinza kwamakhemikhali kuqhubekisela phambili ukuthandeka kwayo ukuze isetshenziswe emikhiqizweni yabathengi.
Enye impahla ebalulekile yeI-TiO2umsebenzi wayo we-photocatalytic, oyivumela ukuthi idale ukusabela kwamakhemikhali lapho ivezwa ekukhanyeni. Lesi sakhiwo sesize ukwakhiwa kwama-photocatalyst asuselwa ku-titanium dioxide ukuze kulungiswe imvelo, ukuhlanzwa kwamanzi, nokulawula ukungcoliswa komoya. Ukwengeza, i-TiO2 iyimpahla ye-semiconductor enezinhlelo zokusebenza ezingase zibe khona kumaseli elanga namadivayisi we-photovoltaic ngenxa yekhono layo lokudonsa amandla elanga futhi liguqule libe amandla kagesi.
Ukusetshenziswa kwe-titanium dioxide:
Izakhiwo ezihlukahlukene ze-TiO2 zivula indlela yokusetshenziswa kwayo okubanzi ezimbonini ezihlukahlukene. Emkhakheni wezokwakha, i-titanium dioxide isetshenziswa njenge-pigment kumapende, ama-coatings kanye nokhonkolo ukunikeza ubumhlophe, ukukhanya nokuqina. Ukumelana kwayo ne-UV futhi kuyenza ilungele ukusetshenziswa kwangaphandle okufana nezingubo zezakhiwo nezinto zokwakha.
Emikhiqizweni yezimonyo neyokunakekelwa komuntu siqu, i-titanium dioxide iyisithako esivamile kuma-sunscreen, ama-lotions kanye nemikhiqizo yokunakekelwa kwesikhumba ngenxa yekhono layo lokuhlinzeka ngokuvikeleka okuphumelelayo kwe-UV. Izakhiwo zayo ezingenabuthi kanye ne-hypoallergenic ziyenza ifanelekele ukusetshenziswa ekwakhiweni kwesikhumba esibucayi, okuyenza ibe ukukhetha okudumile phakathi kwabathengi.
Ngaphezu kwalokho, i-titanium dioxide isetshenziswa kabanzi ezimbonini zokudla nemithi njengombala wokudla, umbala omhlophe kumaphilisi namaphilisi. Ukungangeni kwayo kanye nokungenzi lutho kabusha kuqinisekisa ukuphepha kwayo ukuthi isetshenziswe emikhiqizweni yabathengi, kuyilapho ukukhanya kwayo okuphezulu nokukhanya kuthuthukisa ukukhanga okubonakalayo kokudla kanye nokwakheka kwemithi.
Ngaphezu kwalokho, izakhiwo ze-photocatalytic ze-titanium dioxide ziye zaholela ekusetshenzisweni kwayo kwezemvelo kanye nobuchwepheshe obuhlobene namandla. Ama-photocatalyst asekelwe ku-TiO2 asetshenziselwa ukuhlanzwa komoya namanzi, ukucekelwa phansi kokungcola, nokukhiqizwa kwe-hydrogen ngokusebenzisa ukuhlukaniswa kwamanzi nge-photocatalytic. Lezi zicelo zinesethembiso sokuxazulula izinselelo zemvelo kanye nokuthuthukisa izixazululo zamandla esimeme.
Sekuhlanganiswe ndawonye, izakhiwo ze-tio2 kanye nezinhlelo zokusebenza kugcizelela ukubaluleka kwayo ezimbonini ezihlukahlukene njengezokwakha nezimonyo ekulungiseni imvelo kanye nobuchwepheshe bamandla. Njengoba ucwaningo nokuqamba okusha kuqhubeka nokwandisa ukuqonda kwe-TiO2, amandla ayo ezinhlelo zokusebenza ezisafufusa azoqhubekisela phambili isayensi yezinto zokwakha kanye nobuchwepheshe obuqhubekayo.
