Titanium dioxide, eo ka tloaelo e tsejoang e le Tio2, ke 'mala o mosoeu o nang le mekhoa e mengata e sebelisoang liindastering tse sa tšoaneng. Titanium dioxide rutile phofo ke mofuta oa titanium dioxide e bohlokoa ka ho khetheha bakeng sa index ea eona e phahameng ea refractive le thepa e babatsehang ea ho hasanya leseli. Ho utloisisa ts'ebetso ea tlhahiso ea rutile titanium dioxide phofo ke ea bohlokoa ho baetsi le bareki ho utloisisa boleng ba eona le lits'ebetso.
Tlhahiso ea rutile titanium dioxide phofo e kenyelletsa mehato e 'maloa ea bohlokoa, ho qala ka ho ntšoa ha ore ea titanium, e kang ilmenite kapa rutile. Joale ores tsena li sebetsoa ho fumana titanium dioxide e hloekileng, e ntseng e hloekisoa ho feta ho hlahisa mofuta o hlokahalang oa rutile. Se latelang ke kakaretso ea ts'ebetso ea tlhahiso ea titanium dioxide rutile phofo:
1. Ho ntšoa le ho hloekisoa ha tšepe: Mohato oa pele oa tlhahiso ea phofo ea rutile titanium ke ho ntša tšepe ea titanium ho tsoa liminerale. Ilmenite le rutile ke mehloli e tloaelehileng ea titanium dioxide. Ka mor'a hore tšepe e fumanoe, e tlameha ho feta letotong la mekhoa ea ho hloekisa ho tlosa litšila le ho fumana tekanyo e phahameng ea titanium dioxide.
2. Chlorination le oxidation: Titanium dioxide e hloekisitsoeng e ntan'o kena tšebetsong ea chlorination, e sebetsanang le chlorine ho etsa titanium tetrachloride (TiCl4). Joale motsoako ona o tšeloa oksijene ho hlahisa motsoako oa titanium dioxide le lihlahisoa tse ling.
3. Hydrolysis le calcination: Motsoako o hlahisoang ke hydrolyzed ho fana ka titanium dioxide ka sebōpeho sa eona sa metsi. Joale pula ena e calcined ka mocheso o phahameng ho tlosa metsi le ho e fetola sebopeho sa kristale se lakatsehang. Ts'ebetso ea calcination e bohlokoa ho khethollang thepa le boleng ba ho qetelarutile titanium dioxidephofo.
4. Phekolo ea holim'a metsi: E le ho ntlafatsa ho hasana le ho lumellana ha rutile titanium dioxide ka mekhoa e sa tšoaneng, phekolo ea holim'a metsi e ka etsoa. Sena se kenyelletsa ho koahela bokaholimo ba likaroloana ka metsoako ea tlhaho kapa ea tlhaho ho ntlafatsa ts'ebetso ea bona le botsitso mekhoeng e fapaneng.
5. Taolo ea Boleng le Packaging: Ho pholletsa le ts'ebetso eohle ea tlhahiso, mehato ea ho laola boleng e sebelisoa ho netefatsa bohloeki, kabo ea boholo ba likaroloana le litšobotsi tse ling tsa bohlokoa tsa rutile titanium dioxide phofo. Hang ha phofo e finyella litekanyetso tse hlokahalang, e kenngoa 'me e loketse ho abeloa basebelisi ba ho qetela.
Tlhahiso ea rutile titanium dioxide e hloka taolo e hlokolosi ea litekanyo tse fapaneng, ho kenyelletsa khetho ea thepa e tala, maemo a ts'ebetso le mekhoa ea morao-rao ea ts'ebetso. Baetsi ba sebetsa ho ntlafatsa lintlha tsena ho fumana boholo bo lakatsehang, sebopeho sa kristale le thepa ea holim'a metsi ho fihlela litlhoko tse ikhethang tsa lits'ebetso tse fapaneng.
Rutile titanium dioxide phofo e sebelisoa haholo ka lipente, liphahlo, lipolasetiki le lihlahisoa tse ling 'me e nkoa e le ea bohlokoa ka lebaka la khanya ea eona e phahameng, khanya le thepa ea tšireletso ea UV. Ka ho utloisisa ts'ebetso ea tlhahiso ea rutile titanium dioxide phofo, bahlahisi ba ka fetola thepa ea eona ho finyella litlhoko tsa ts'ebetso ea sehlahisoa sa ho qetela, ha bareki ba ka ananela boleng le ts'ebetso ea pigment ena ea bohlokoa e tšoeu.
Ka kakaretso, tlhahiso ea rutilephofo ea titanium dioxidee kenyelletsa letoto le rarahaneng la mehato ea ho tloha ho ntšoa ha tšepe ho ea ho kalafo ea holim'a metsi ho hlahisa li-pigments tsa boleng bo holimo tsa titanium dioxide tse nang le lisebelisoa tse ntle tsa ho hasanya leseli. Kutloisiso ena ke ea bohlokoa bakeng sa bahlahisi le basebelisi ho hlokomela bokhoni bo felletseng ba titanium dioxide rutile powders lits'ebetsong tse fapaneng.
