Titanium dioxide (TiO2) ke pigment e tšoeu e feto-fetohang e sebelisoang liindastering tse fapaneng, ho kenyeletsoa lipente, liaparo, polasetiki le litlolo. Lintho tsa eona tse ikhethang li etsa hore e be motsoako oa bohlokoa ho finyella 'mala o lakatsehang, opacity le khanya ea sehlahisoa sa hau. Leha ho le joalo, molemong oa ho hlokomela melemo ea titanium dioxide ka botlalo, ho bohlokoa ho netefatsa phallo e sebetsang nakong ea ts'ebeliso. Phallo e nepahetseng ea phofo ea TiO2 kapaho hasana ha titanium dioxideho bohlokoa ho eketsa ts'ebetso ea eona le ho fihlela sephetho se lakatsehang. Sehloohong sena re tla sheba malebela a ho hasanya titanium dioxide ka katleho ho ntlafatsa ts'ebeliso ea eona liindastering tse fapaneng.
1. Utloisisa ho hasana ha titanium dioxide
Pele o kenella ka malebela a ho hasana ka katleho, ho bohlokoa ho utloisisa mohopolo oa ho hasana le bohlokoa ba ona lits'ebetsong tsa titanium dioxide. Dispersion e bolela kabo e ts'oanang ea likaroloana tsa TiO2 sebakeng se joalo ka mokelikeli kapa matrix a tiileng. Phallo e nepahetseng e tiisa kabo e ts'oanang ea likaroloana tsa titanium dioxide, ho thibela ho kopana le ho khothaletsa ts'ebetso e nepahetseng ea sehlahisoa sa ho qetela.
2. Khetha mokhoa o nepahetseng oa ho hasanya titanium dioxide
Ho na le mekhoa e mengata ea ho hasana bakeng satitanium dioxide, ho kenyelletsa ho hasana ho metsi, ho hasana ho omileng, phekolo ea holim'a metsi, joalo-joalo Khetho ea mokhoa oa ho hasana e itšetlehile ka ts'ebeliso e khethehileng le thepa ea TiO2 ea ho hasana. Ka mohlala, indastering ea ho penta le ea ho roala, ho hasana ha metsi ho atisa ho etsoa ho sebelisoa li-dispersers tse lebelo le phahameng kapa mechine ea mecha ea litaba ho finyella kabo ea likaroloana tse tšoanang.
3. Sebelisa lihlahisoa tsa boleng bo phahameng ba titanium dioxide
Boleng ba titanium dioxide phofo kapa ho hasana ho phetha karolo ea bohlokoa ho finyella ho hasana ka katleho. Lihlahisoa tsa boleng bo holimo tsa titanium dioxide li tlameha ho tsoa ho barekisi ba tšepahalang ho netefatsa boholo ba likaroloana, sebopeho le pheletso e holimo. Lihlahisoa tsa boleng bo holimo tsa titanium dioxide li hasana habonolo mme li fana ka ts'ebetso e ntlafalitsoeng lits'ebetsong tse fapaneng.
4. Ntlafatsa foromo le litekanyetso tsa ts'ebetso
Ntle le ho khetha mokhoa o nepahetseng oa ho hasana le lihlahisoa tsa boleng bo holimo tsa TiO2, ho ntlafatsa sebopeho le liparamente tsa ts'ebetso ho bohlokoa hape ho fihlela phallo e sebetsang. Lintho tse kang titanium dioxide concentration, khetho ea dispersant, le maemo a ho sebetsa (mohlala, mocheso, shear rate) li ka ama ts'ebetso ea ho hasana haholo. Ka ho lokisa liparamente tsena ka hloko, bahlahisi ba ka khona ho hasana hantle le ho ntlafatsa ts'ebetso ea titanium dioxide lihlahisoa tsa bona.
5. Sebelisa lisebelisoa tse tsoetseng pele tsa ho hasana
Ho tsetela lisebelisoa tse tsoetseng pele tsa ho hasana ho ka ntlafatsa haholo ts'ebetso ea ho hasana le ho eketsa ts'ebeliso ea titanium dioxide. Li-dispers tsa lebelo le phahameng, li-mill tsa bead, le li-homogenizers tsa ultrasonic ke mehlala ea lisebelisoa tse tsoetseng pele tse ka qhalakanyang likaroloana tsa TiO2 ka katleho, ka tsela eo li ntlafatsa ho fana ka mebala, opacity, le ho tšoarella ha sehlahisoa sa ho qetela.
6. Etsa taolo ea boleng le tlhahlobo
Ho etsa bonnete ba ho hasana ho tsitsitseng le ka katleho ha titanium dioxide, taolo e phethahetseng ea boleng le liteko li tlameha ho etsoa nakong eohle ea tlhahiso. Sena se kenyelletsa ho lekola kabo ea boholo ba likaroloana, ho lekola nts'etsopele ea mebala, le ho lekola thepa ea rheological ea ho hasana. Ka ho kenya ts'ebetsong mehato e matla ea ho laola boleng, bahlahisi ba ka tseba le ho rarolla mathata leha e le afe a amanang le ho hasana, kahoo ba ntlafatsa ts'ebetso ea sehlahisoa.
Ka kakaretso, ho eketsalisebelisoa tsa titanium dioxidee hloka tlhokomelo e hlokolosi ts'ebetsong ea ho hasana. Ka ho utloisisa melao-motheo ea ho hasana, ho khetha mokhoa o nepahetseng oa ho hasana, ho sebelisa lihlahisoa tsa boleng bo phahameng ba titanium dioxide, ho ntlafatsa liforomo le mekhoa ea ts'ebetso, ho sebelisa lisebelisoa tse tsoetseng pele tsa ho hasana, le ho laola boleng bo thata, bahlahisi ba ka finyella ho hasana ka katleho le ho lokolla bokhoni bo feletseng ba titanium. dioxide. Monyetla oa sulfur dioxide o ka har'a lihlahisoa tsa bona. Ho hasana ka katleho ha ho ntlafatse ts'ebetso ea titanium dioxide feela, empa hape ho thusa ho ntlafatsa boleng ba kakaretso le ts'ebetso ea sehlahisoa sa ho qetela ho pholletsa le liindasteri.
