I-Titanium dioxide, eyaziwa ngokuba yi-TiO2, i-compound esebenzayo eye yatsala ingqalelo ebanzi ngenxa yeempawu zayo ezizodwa kunye noluhlu olubanzi lwezicelo. Kule bhlog, siza kugocagoca kwiipropathi zeTiO2 kwaye siphonononge usetyenziso lwayo olwahlukeneyo kumashishini ahlukeneyo.
Iimpawu ze-titanium dioxide:
I-TiO2 yindalo ye-titanium oxide eyaziwayo ngeempawu zayo ezikhethekileyo. Enye yeempawu zayo eziphawulekayo yi-index ephezulu ye-refractive, eyenza ibe yi-pigment emhlophe ebalaseleyo kwiipende, iingubo kunye neeplastiki. Ukongeza, i-titanium dioxide inokumelana okuphezulu kwe-UV, iyenza ibe lukhetho oludumileyo lwe-sunscreen kunye nezixhobo zokuthintela i-UV. Ubume bayo obungenatyhefu kunye nozinzo lwekhemikhali luqhubela phambili ukukhulisa umtsalane wayo ukuze isetyenziswe kwiimveliso zabathengi.
Enye ipropati engundoqo yeI-TiO2ngumsebenzi wayo we-photocatalytic, owuvumelayo ukuba wenze utshintsho lwekhemikhali xa ubekwe ekukhanyeni. Le propati iququzelele ukuphuhliswa kwe-titanium dioxide-based photocatalysts yokulungiswa kokusingqongileyo, ukucocwa kwamanzi, kunye nokulawula ukungcoliseka komoya. Ukongeza, i-TiO2 yimpahla ye-semiconductor enezicelo ezinokubakho kwiiseli zelanga kunye nezixhobo ze-photovoltaic ngenxa yokukwazi ukufunxa amandla elanga kunye nokuguqula amandla ombane.
Ukusetyenziswa kwe-titanium dioxide:
Iipropati ezahlukeneyo ze-TiO2 zivula indlela yokusetyenziswa kwayo ngokubanzi kumashishini ahlukeneyo. Kwicandelo lokwakha, i-titanium dioxide isetyenziswa njenge-pigment kwiipende, iingubo kunye nekhonkrithi ukunika ubumhlophe, ukukhanya kunye nokuqina. Ukunganyangeki kwayo kwe-UV kukwenza ukuba ilungele usetyenziso lwangaphandle olunje ngokutyabeka kwezakhiwo kunye nezixhobo zokwakha.
Kwizinto zokuthambisa kunye neemveliso zokunyamekela, i-titanium dioxide yinto eqhelekileyo kwi-sunscreens, i-lotions kunye nemveliso yokunakekelwa kwesikhumba ngenxa yokukwazi ukubonelela ngokukhuselekileyo kwe-UV. Iimpawu zayo ezingenayo i-toxic kunye ne-hypoallergenic ziyenza ilungele ukusetyenziswa kwi-formulation yesikhumba esibucayi, okwenza kube lukhetho oludumileyo phakathi kwabathengi.
Ukongezelela, i-titanium dioxide isetyenziswa ngokubanzi kumashishini okutya kunye namayeza njengombala wokutya, i-pigment emhlophe kwiipilisi kunye neepilisi. I-inertness yayo kunye ne-non-reactivity iqinisekisa ukhuseleko lwayo ukuze isetyenziswe kwiimveliso zabathengi, ngelixa ukukhanya kwayo okuphezulu kunye nokukhanya kwayo kwandisa ukubukeka okubonakalayo kokutya kunye nokuqulunqwa kwamayeza.
Ukongeza, iipropathi ze-photocatalytic ze-titanium dioxide ziye zakhokelela ekusebenziseni kwayo kwindalo kunye nobuchwephesha obunxulumene namandla. I-photocatalysts esekelwe kwi-TiO2 isetyenziselwa ukuhlanjululwa komoya kunye namanzi, ukuchithwa kokungcola, kunye nokuveliswa kwe-hydrogen ngokusebenzisa i-photocatalytic water splitting. Ezi zicelo zibambe isithembiso sokusombulula imingeni yokusingqongileyo kunye nokuqhubela phambili izisombululo zamandla azinzileyo.
Zithathiwe kunye, iipropati ze-tio2 kunye nokusetyenziswa kugxininisa ukubaluleka kwayo kumashishini ahlukeneyo njengolwakhiwo kunye nezithambiso zokulungiswa kwendalo kunye nobuchwepheshe bamandla. Njengoko uphando kunye nokuveliswa kwezinto ezintsha kuqhubeka ukwandisa ukuqonda kwe-TiO2, ukubanakho kwezicelo ezivelayo kuya kuqhubela phambili isayensi yezinto kunye nobuchwepheshe obuzinzileyo.
