Titanium dioxide (TiO2) ke sehlahisoa sa bohlokoa sa lik'hemik'hale sa inorganic, se nang le ts'ebeliso ea bohlokoa ho litlolo, li-inks, ho etsa pampiri, rabara ea polasetiki, fiber ea lik'hemik'hale, lirafshoa le liindasteri tse ling. Titanium dioxide (lebitso la Senyesemane: titanium dioxide) ke pigment e tšoeu eo karolo ea eona e kholo e leng titanium dioxide (TiO2). Lebitso la saense ke titanium dioxide (titanium dioxide), 'me foromo ea molek'hule ke TiO2. Ke motsoako oa polycrystalline oo likaroloana tsa oona li hlophisoang kamehla 'me li na le sebopeho sa lattice. Tekanyo e lekanyelitsoeng ea titanium dioxide ke e nyenyane ka ho fetisisa. Ts'ebetso ea tlhahiso ea titanium dioxide e na le litsela tse peli tsa ts'ebetso: mokhoa oa sulfuric acid le mokhoa oa chlorination.
Lintlha tse ka sehloohong:
1) Boima ba kamano
Har'a li-pigment tse tšoeu tse sebelisoang ka tloaelo, ho teteana ha titanium dioxide ke ho honyenyane ka ho fetisisa. Har'a li-pigments tse tšoeu tsa boleng bo tšoanang, sebaka se ka holimo sa titanium dioxide ke sona se seholo ka ho fetisisa 'me molumo oa pigment ke o moholo ka ho fetisisa.
2) Sebaka sa ho qhibiliha le ntlha e belang
Kaha mofuta oa anatase o fetoha mofuta oa rutile mocheso o phahameng, ntlha ea ho qhibiliha le ntlha e belang ea anatase titanium dioxide ha e le hantle ha e eo. Ke feela rutile titanium dioxide e nang le ntlha e qhibilihang le ntlha e belang. Sebaka sa ho qhibiliha sa rutile titanium dioxide ke 1850 ° C, sebaka se qhibilihisang moeeng ke (1830 ± 15) ° C, 'me sebaka se qhibilihisang ka oksijene e ruileng ke 1879 ° C. Sebaka sa ho qhibiliha se amana le bohloeki ba titanium dioxide. . Sebaka se belang sa rutile titanium dioxide ke (3200±300)°C,' me titanium dioxide e fetoha hanyenyane mochesong ona o phahameng.
3) Dielectric kamehla
Titanium dioxide e na le lisebelisoa tse ntle tsa motlakase ka lebaka la boemo ba eona bo phahameng ba dielectric. Ha ho etsoa qeto ea lintho tse ling tsa 'mele tsa titanium dioxide, tataiso ea crystallographic ea likristale tsa titanium dioxide e lokela ho nkoa. Dielectric constant ea anatase titanium dioxide e batla e le tlase, ke 48 feela.
4) Conductivity
Titanium dioxide e na le thepa ea semiconductor, conductivity ea eona e eketseha ka potlako ka mocheso, 'me e boetse e na le bothata bo boholo ba khaello ea oksijene. Thepa ea dielectric kamehla le semiconductor ea rutile titanium dioxide e bohlokoa haholo indastering ea elektronike, 'me thepa ena e ka sebelisoa ho hlahisa likarolo tsa elektronike tse kang li-ceramic capacitors.
5) Ho thatafala
Ho ea ka tekanyo ea boima ba Mohs, rutile titanium dioxide ke 6-6.5, 'me anatase titanium dioxide ke 5.5-6.0. Ka hona, ho timela ha fiber ea lik'hemik'hale, mofuta oa anatase o sebelisoa ho qoba ho roala ha masoba a spinneret.
6) Hygroscopicity
Le hoja titanium dioxide e le hydrophilic, hygroscopicity ea eona ha e matla haholo, 'me mofuta oa rutile o monyenyane ho feta mofuta oa anatase. The hygroscopicity ea titanium dioxide e na le kamano e itseng le boholo ba sebaka sa eona se ka holimo. Sebaka se seholo sa holim'a metsi le hygroscopicity e phahameng li boetse li amana le phekolo ea holim'a metsi le thepa.
7) Ho tsitsa ha mocheso
Titanium dioxide ke thepa e nang le botsitso bo botle ba mocheso.
8) Granularity
Kabo ea boholo ba likaroloana tsa titanium dioxide ke index e pharaletseng, e amang ka botebo ts'ebetso ea mebala ea titanium dioxide le ts'ebetso ea kopo ea sehlahisoa. Ka hona, puisano ea matla a koahelang le dispersibility e ka hlahlojoa ka ho toba ho tloha kabong ea boholo ba likaroloana.
Lintlha tse amang kabo ea boholo ba likaroloana tsa titanium dioxide li rarahane. Ea pele ke boholo ba boholo ba phatsa ea pele ea hydrolysis. Ka ho laola le ho lokisa maemo a ts'ebetso ea hydrolysis, boholo ba karolo ea mantlha bo ka har'a mefuta e itseng. Ea bobeli ke mocheso oa calcination. Nakong ea calcination ea metatitanic acid, likaroloana li kena ka nako ea phetoho ea kristale le nako ea ho hōla, 'me mocheso o loketseng o laoloa ho etsa likaroloana tsa ho hōla ka har'a mefuta e itseng. Mohato oa ho qetela ke pulverization ea sehlahisoa. Hangata, phetoho ea leloala la Raymond le tokiso ea lebelo la analyzer li sebelisoa ho laola boleng ba pulverization. Ka nako e ts'oanang, lisebelisoa tse ling tsa pulverizing li ka sebelisoa, tse kang: pulverizer ea lebelo le phahameng, jet pulverizer le hamore Mills.
