Titanium dioxide, eyaziwa kakhulu ngokuthi iTio2, iyinkimbinkimbi esebenzayo edonsele ukunakwa okubanzi ngenxa yezakhiwo zayo ezihlukile nezinhlobonhlobo zezicelo. Kule bhulogi, sizokwelulela ezakhiweni zeTio2 futhi sihlole izicelo zayo ezahlukahlukene ezimbonini ezahlukahlukene.
Izakhiwo ze-titanium dioxide:
I-Tio2 yenzeka ngokwemvelo ye-titanium oxide eyaziwa ngezakhiwo zayo ezihlukile. Enye yezakhiwo zayo eziphawuleka kakhulu iyinkomba yayo ephezulu yokuvunyelwa, eyenza kube yi-pigment enhle kakhulu emhlophe ngopende, izimbobo namapulasitiki. Ngokwengeziwe, titanium dioxide inokumelana okuphezulu kwe-UV, okwenza kube yindlela ethandwayo yokukhanya kwelanga kanye nezinto zokwakha ze-UV. Imvelo yayo ye-nontoxic kanye nokuqina kwamakhemikhali kukhulisa ukuheha kwayo ukusetshenziselwa imikhiqizo yabathengi.
Enye impahla ebalulekile yeTio2ngumsebenzi wayo we-photocatalytic, ukuvumela ukuthi kunciphise ukusabela kwamakhemikhali lapho kuvezwa ukukhanya. Le mpahla ihambise ukuthuthukiswa kwe-photocatalysts esekelwe ku-titonium dioxide-based for Remediation yezemvelo, ukuhlanzwa kwamanzi, kanye nokulawulwa komoya. Ngaphezu kwalokho, i-Tio2 iyizinto ezisetshenziswayo ze-semiconductor ezinokusetshenziswa kwamangqamuzana elanga kanye namadivayisi we-photovoltaic ngenxa yekhono lawo lokudonsa amandla elanga bese uyiguqula ibe amandla kagesi.
Izicelo ze-titanium dioxide:
Izakhiwo ezahlukahlukene ze-Tio2 zibeka indlela yohlelo lokusebenza lwayo olubanzi ezimbonini ezahlukahlukene. Emkhakheni wezokwakha, i-titanium dioxide isetshenziswa njengengulube kumapende, ukumboza kanye nokhonkolo ukuze idlulisele i-mporess, opacity kanye nokuqina. Ukumelana kwayo i-UV nakho kwenza kube kuhle ngezicelo zangaphandle ezifana nezembatho zokwakha kanye nezinto zokwakha.
Ezimonyo zemikhiqizo yokunakekelwa komuntu siqu, i-titanium dioxide iyisithako esivamile kuma-sunscreens, imikhiqizo yokunakekelwa kwesikhumba ngenxa yekhono layo lokuhlinzeka ngokuvikelwa okusebenzayo kwe-UV. Izakhiwo zalo ezingezona zobuthi kanye ne-hypoallergenic zenza zilungele ukusetshenziswa ekwakhiweni kwesikhumba okubucayi, okwenza kube ukukhetha okuthandwa phakathi kwabathengi.
Ngaphezu kwalokho, i-titanium dioxide isetshenziswa kabanzi kuzimboni zokudla kanye nemithi njengoba kunemibala yokudla, umbala omhlophe ezibhebheni namaphilisi. Ukungena kwayo nokungabi nalo runivity kuqinisekisa ukuphepha kwayo ukuze kusetshenziswe emikhiqizweni yabathengi, kanti ukugqama kwayo okuphezulu nokukhanya kuthuthukisa isikhalazo esibonakalayo sokudla kanye nokwakheka kwemithi.
Ngaphezu kwalokho, izakhiwo ze-photocatalytic zeTitanium Dioxide ziholele ekusetshenzisweni kwazo kubuchwepheshe obuhlobene nezemvelo nakwamandla. Ama-photocatalysts asuselwa ku-Tio2 asetshenziselwa ukuhlanzwa komoya nokuhlanza amanzi, ukucekelwa phansi kwamanzi, nokukhiqizwa kwe-hydrogen ngokusebenzisa ama-photocatalytic amanzi aqhekekayo. Lezi zinhlelo zokusebenza zibamba isithembiso sokuxazulula izinselelo zemvelo kanye nokuthuthuka kwezixazululo zamandla esimeme.
Ithathwe ndawonye, izakhiwo ze-Tio2 nezinhlelo zigcizelela ukubaluleka kwayo ezimbonini ezihlukile njengokwakhiwa kanye nezimonyo ekubuyiselweni kwezemvelo nobuchwepheshe bamandla. Njengoba ucwaningo kanye nokwenziwa okusha kuyaqhubeka ukwandisa ukuqonda kwe-Tio2, amandla alo ezicelo ezifufusa kuzothuthukisa ukuthuthuka kwesayensi yesayensi kanye nobuchwepheshe obuzinzile.
