I-Titanium Dioxide (Tio2) ingumkhiqizo obalulekile wamakhemikhali we-Inorganic, onokusetshenziswa okubalulekile ku-Coatings, ama-inks, amapakethe, irabha yepulasitiki, amakhemikhali amakhemikhali, ubuciko be-ceramics kanye nezinye izimboni. I-Titanium dioxide (igama lesiNgisi: titanium dioxide) yingulube emhlophe yengxenye yayo eyinhloko yiTitanium Dioxide (Tio2). Igama lesayensi yiTitanium Dioxide (Titanium Dioxide), kanye nefomula ye-molecular yi-tio2. Yindawo ye-polycrystalline enezinhlayiyana ezihlelwe njalo futhi zibe nesakhiwo se-lattice. Ubuningi obusondelene be-titanium dioxide buncane kakhulu. Inqubo yokukhiqiza yeTitanium Dioxide inemizila emibili yenqubo: Indlela ye-Sulfuric Acid nendlela ye-Chlorination.
Izici eziyinhloko:
1) Ubuningi obuhlobene
Phakathi kwemibala emhlophe esetshenziswa kakhulu, ubuningi obuhlobene ne-titanium dioxide buncane kakhulu. Phakathi kwemibala emhlophe yekhwalithi efanayo, indawo engaphezulu ye-titanium dioxide enkulu kunazo zonke futhi ivolumu ye-pigment inkulu kakhulu.
2) Iphoyinti lokuncibilika nephuzu elibilayo
Njengoba uhlobo lwe-anatase luguqula lube uhlobo lwe-ruter ngokushisa okuphezulu, indawo yokuncibilika kanye nephuzu lokubilisa le-anatase titanium dioxide empeleni ayikho. I-rutile titanium dioxide kuphela enendawo yokuncibilika nephuzu elibilayo. Iphoyinti elincibilikayo le-rutile titanium dioxide lingu-1850 ° C, iphuzu elincibilikayo emoyeni lingu (1830 ± 15) ° C, kanye nephuzu lokuncibilika ku-1879 ° C. Iphuzu lokuncibilika lihlobene ne-Titanium Dioxide. Iphoyinti elibilayo le-rutile titanium dioxide (3200 ± 300) ° C, kanye ne-titanium dioxide kuguquguquka kancane kulokhu okushisa okuphezulu.
3) dielectric njalo
I-Titanium Dioxide inezindawo ezinhle kakhulu zikagesi ngenxa ye-dielectric yayo ephakeme njalo. Lapho unquma ezinye izakhiwo ezibonakalayo ze-titanium dioxide, ukuqondiswa kwe-crystagographic kwamakristalu e-titanium dioxide kufanele kubhekwe. I-dielectric ihlala njalo ye-anatase titanium dioxide iphansi, 48 kuphela.
4) Ukuvuselelwa
I-Titanium dioxide inezakhiwo ze-semiconductor, ukuhanjiswa kwayo kwanda ngokushesha ngamazinga okushisa, futhi kuyazwela kakhulu ekusholeni komoya-mpilo. Izici ze-dielectric ezihlala njalo ne-semielenductor ye-rutile titanium dioxide zibaluleke kakhulu embonini yama-elekthronikhi, futhi lezi zakhiwo zingasetshenziswa ukukhiqiza izakhi ze-elektroniki ezifana nama-capacic ceracic.
5) Ubulukhuni
Ngokwesilinganiso sobulukhuni be-mohts, i-rutile titanium dioxide ngu-6-6,5, kanye ne-anatase titanium dioxide ngu-5.5-6.0. Ngakho-ke, ekuqothulweni kwamakhemikhali amakhemikhali, uhlobo lwe-anatase lusetshenziselwa ukugwema ukugqokwa kwezimbobo ze-spinner.
6) Hygroscopicity
Yize i-titanium dioxide i-hydrophilic, i-hyrroscoscopicity ayinamandla, futhi uhlobo lwe-ruter luncane kunohlobo lwe-anatase. I-hygroscopicity ye-titanium dioxide inobudlelwano obuthile nobukhulu bendawo yayo engaphezulu. Indawo enkulu engaphezulu kanye nenhlayiya ephezulu kuhlobene nokulashwa komhlaba nasezakhiweni.
7) Ukuqina okushisayo
I-Titanium Dioxide iyinto enokuqina okuhle okushisayo.
8) Granularity
Ukusatshalaliswa kosayizi wezinhlayiyana kweTitanium Dioxide kuyinkomba ebanzi, okuthinta kakhulu ukusebenza kwemibala ye-titanium dioxide kanye nokusebenza kohlelo lomkhiqizo. Ngakho-ke, ingxoxo yokumboza amandla nokuhlakazwa kungahlaziywa ngokuqondile kusuka ekusatshalalisweni kosayizi wezinhlayiyana.
Izici ezithinta ukusatshalaliswa kosayizi wezinhlayiyana ze-titanium dioxide kuyinkimbinkimbi. Owokuqala usayizi wosayizi wokuqala wezinhlayiya we-hydrolysis. Ngokulawula nokushintsha izimo zenqubo ye-hydrolysis, ubukhulu bezinhlayiyana bokuqala bungaphakathi kwebanga elithile. Okwesibili izinga lokushisa lezezimali. Ngesikhathi sekhayithi le-metatitanic acid, izinhlayiya zibhekana nesikhathi sokuguqulwa kwe-crystal kanye nesikhathi sokukhula, futhi izinga lokushisa elifanele lilawulwa ukwenza izinhlayiya zokukhula ngaphakathi kwebanga elithile. Isinyathelo sokugcina ukucaphuka komkhiqizo. Imvamisa, ukuguqulwa kwe-raymond mill kanye nokulungiswa kwejubane le-analyzer kusetshenziselwa ukulawula ikhwalithi yokugaya. Ngasikhathi sinye, eminye imishini yokugaya ingasetshenziswa, njenge: i-pulverizer ephezulu ye-pulverizer, Jet Puliverizer kanye ne-Hammer Mills.
