Anatase titanium dioxide ke ea pigment grade titanium dioxide, e nang le matla a koahelang a matla, matla a holimo a tinting, ho hanyetsa boemo ba leholimo le litšobotsi tse ling, tse latelang li latela pigment ea silevera ea pere ho utloisisa mokhoa oa ho ntlafatsa ts'ebetso ea ts'ebetso ea ts'ebetso ea anatase titanium dioxide.

1, tsela e ka sehloohong ea ho ntlafatsa le ho tsitsisa bosoeu ba titanium dioxide

Bosoeu ba titanium dioxide bo susumetsoa ke lintlha tse ngata, ho kenyelletsa mohloli oa liminerale, lisebelisoa le theknoloji ea bohlokoa.Ka liteko le phihlelo ea tšimo, lintlha tse ka sehloohong tse amang bosoeu ba eona ke: boleng ba hydrolysis, ho tlosoa ha lintho tse sa hloekang le maemo a calcination.

Hona joale, ho na le mefuta e 'meli ea theknoloji ea hydrolysis ea titanium dioxide Chaena, khatello ea hydrolysis le atmospheric hydrolysis.Ho tsoa tlhahlobong ea boleng ba hydrolysis le boleng ba sehlahisoa, boleng ba sepakapaka sa hydrolysis bo molemo, ho lekana ha boholo ba hydrolysis.Boleng ba hydrolysis bo lokela ho ntlafatsoa, ​​index ea boleng ba tharollo ea titanium e tsepamisitsoeng e lokela ho laoloa ka thata, karo-karolelano ea tšepe ho titanium le litaba tse tiileng li lokela ho laoloa ka har'a mefuta e behiloeng, 'me maemo a ts'ebetso ea hydrolysis a eketsehe.

Ntho e 'ngoe e ka sehloohong e amang bosoeu ba titanium dioxide ke litšila tse ling tse mebala-bala, tse kang: tšepe, cobalt, nickel, joalo-joalo, e tlameha ho nka mehato e itseng ea ho tlosa, bakeng sa anatase titanium dioxide, e nang le tšepe e phahameng ka 120ppm, e ama bosoeu ba eona, esita le. phetoho ya mmala o kganyang.U sebelisa theknoloji ea bleaching, eketsa matla a ho hlatsoa a tšepe e phahameng, ha u ntse u eketsa lisebelisoa tse ling tsa masking, tse kang antimony trioxide le phosphoric acid, ho masking e rarahaneng ea tšepe, ho fokotsa tšusumetso ea litšila ho titanium dioxide bosoeu.

Taolo ea maemo a calcination ke karolo ea bohlokoa ea moralo oa titanium dioxide kristale konokono, molemo calcination mocheso, ka etsa hore titanium dioxide desulfurization, dehydration ka ho feletseng, ka hohle kamoo ho ka khonehang ho qoba lattice sekoli ea titanium dioxide kristale konokono, le ama bosoeu ba eona. .Ka hona, eketsa taolo ea lintlha tsa bohlokoa tsa mocheso, ka nako e ts'oanang etsa hore lijo li fepe le lebelo la sebōpi le utloahalang, eketsa kamore ea mollo, qoba ho kopana pakeng tsa thepa le lelakabe, sintering.

2, kabo ea boholo bo tsitsitseng ba titanium dioxide, e ntlafatsa phepelo ea titanium dioxide le matla a koahelang

Kabo ea boholo ba phatsa ea titanium dioxide ke index e pharaletseng, e amang ka botebo litšobotsi tsa pigment le tšebeliso ea sehlahisoa sa titanium dioxide.Ka hona, puisano ea matla a koahelang le ho hasana 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.Boholo ba phatsa ea mantlha bo ka bolokoa ka mefuta e itseng ka ho laola le ho lokisa maemo a tšebetso ea hydrolysis.Taba ea bobeli, mocheso oa calcination, ts'ebetsong ea calcination ea mettitanic acid, likaroloana li kena ka nako ea phetoho ea kristale le sethala sa kholo, li laola mocheso o loketseng, e le hore ho hōla ha likaroloana ka har'a mefuta e itseng.Ea ho qetela ke ho sila ha sehlahisoa, hangata phetoho ea leloala la Raymond le phetoho ea lebelo la analyzer, taolo ea boleng ba ho sila, ka nako e ts'oanang, lisebelisoa tse ling tsa ho sila li ka sebelisoa, tse kang: leloala lohle la matla, sesebelisoa sa leloala la moea le sesebelisoa sa hamore.

3, ka kalafo ea holim'a metsi, ntlafatsa ts'ebetso ea ts'ebeliso ea titanium dioxide

Titanium dioxide e polar haholo phofo, tlhaho ke hydrophilic le oleophobic, empa haeba holim'a adsorption ea moea, metsi le litšila tse ling, ho qhalana ka metsing ho fokotsehile, hangata ho hlokahala bakeng sa phekolo ea holim'a metsi, moemeli oa phekolo o sebelisoang hangata bakeng sa hydrated alumina le hydrated. silicon oxide.Hona joale, ho boetse ho na le lisebelisoa tse ngata tsa phekolo ea holim'a 'marakeng, tse kang: silicon ea organic, coupling agent, joalo-joalo, kapa li-pigments tse ling tse kang: barium sulfate, aluminium hydroxide, joalo-joalo, ho ntlafatsa litšobotsi tsa bokaholimo. ea titanium dioxide, e ntlafatsa ho hasana ha eona.
