1. Ọrụ titanium dioxide na mkpuchi
Ihe mkpuchi na-abụkarị akụkụ anọ: ihe na-emepụta ihe nkiri, pigmenti, ihe mgbaze na ihe mgbakwunye.Ụdị pigmenti dị na mkpuchi nwere ụfọdụ ike ezoro ezo.Ọ bụghị nanị na ọ na-ekpuchi agba mbụ nke ihe mkpuchi, kamakwa inye mkpuchi ahụ na-egbuke egbuke.Chọpụta mmetụta ịchọ mma nke ọkụ na ịchọ mma.N'otu oge ahụ, a na-ejikọta pigmenti ahụ na onye na-agwọ ọrịa na mkpụrụ osisi, na-ejikọta ya, nwere ike ime ka ike na-arụ ọrụ na-arụ ọrụ na adhesion nke ihe nkiri mkpuchi ahụ, gbochie ịgbawa ma ọ bụ daa, ma nwee ike ịbawanye ọkpụrụkpụ nke ihe nkiri mkpuchi ahụ, gbochie ya. ntinye nke ụzarị ultraviolet ma ọ bụ mmiri, ma melite mkpuchi.Ihe mgbochi ịka nká na ịdịte aka nke ihe nkiri ahụ na-agbatị ndụ ọrụ nke ihe nkiri ahụ na ihe echekwara.
Na pigmenti, ọnụ ọgụgụ nke na-acha ọcha pigmenti dị nnọọ ukwuu, na arụmọrụ chọrọ nke mkpuchi maka agba ọcha: ① Ezi ọcha;②Egweri dị mma na wettability;③Ezigbo iguzogide ihu igwe;④ Ezi nkwụsi ike kemịkalụ;⑤ Obere urughuru nha, ike ezoro ezo na mfu ike agba dị elu, ezigbo opacity na gloss.
Titanium dioxide bụ ụdị pigmenti ọcha nke a na-ejikarị eme ihe na mkpuchi.Ihe mmepụta ya bụ ihe karịrị 70% nke pigmenti inorganic, na oriri ya bụ 95.5% nke ngụkọta oriri nke pigmenti ọcha.Ka ọ dị ugbu a, a na-eji ihe dị ka 60% nke titanium dioxide ụwa na-emepụta ihe mkpuchi dị iche iche, karịsịa rutile titanium dioxide, nke ọtụtụ n'ime ụlọ ọrụ mkpuchi na-eri.Agba nke titanium dioxide mee nwere agba na-egbuke egbuke, ike ezoro ezo dị elu, ike tinting siri ike, obere usoro onunu ogwu, na ọtụtụ ụdị.Ọ na-echebe nkwụsi ike nke onye na-ajụ ya, ma nwee ike ịkwalite ike ọrụ na ntinye nke ihe nkiri agba, gbochie mgbawa, ma gbochie ụzarị ultraviolet.Ọ na-abanye na mmiri ma mee ka ndụ nke ihe nkiri agba dịkwuo ogologo.Agba nke dabara na ihe fọrọ nke nta ka ọ bụrụ ụkpụrụ ọ bụla dị na agba ụkpụrụ mara mma enweghị ikewapụ ya na titanium dioxide.
Ụdị mkpuchi dị iche iche maka ebumnuche dị iche iche nwere ihe dị iche iche chọrọ maka titanium dioxide.Dịka ọmụmaatụ, mkpuchi ntụ ntụ chọrọ iji rutile titanium dioxide nwere ezigbo dispersibility.Anatase titanium dioxide nwere obere ike decolor na ọrụ photochemical siri ike.Mgbe a na-eji ihe mkpuchi ntụ ntụ, ihe nkiri mkpuchi na-adịkarị mfe na-acha odo odo.Rutile titanium dioxide nke usoro sulfuric acid na-emepụta nwere uru nke ọnụahịa dị oke ọnụ, mgbasa ozi dị mma, ike nzuzo dị mma na ike ibelata agba, ọ dịkwa mma maka mkpuchi ntụ ntụ ime ụlọ.Na mgbakwunye na nkesa dị mma, izobe ike na agba na-ebelata ike, titanium dioxide maka mkpuchi ntụ ntụ n'èzí na-achọkwa ihu igwe dị mma.Ya mere, titanium ntụ ntụ maka mkpuchi ntụ ntụ n'èzí bụ n'ozuzu rutile titanium dioxide nke chlorination mepụtara.
2. Nyocha nke mmetụta nke isi àgwà mgbanwe nke titanium dioxide na coatings
1 ọcha
A na-eji titanium dioxide mee ihe dị ka pigmenti ọcha maka mkpuchi.Ọcha ya dị oke mkpa ma bụrụ otu n'ime ihe ngosi njirimara dị mkpa nke mkpuchi mkpuchi chọrọ.Ọcha na-adịghị mma nke titanium dioxide ga-emetụta ọdịdị nke ihe nkiri mkpuchi ozugbo.Isi ihe na-emetụta ịdị ọcha nke titanium dioxide bụ ụdị na ọdịnaya nke adịghị ọcha na-emerụ ahụ, n'ihi na titanium dioxide na-enwe mmetụta nke ọma na adịghị ọcha, karịsịa rutile titanium dioxide.
Ya mere, ọbụlagodi obere ihe adịghị ọcha ga-enwe mmetụta dị ukwuu na ọcha nke titanium dioxide.Ịcha ọcha nke titanium dioxide nke usoro chloride na-emepụta na-adịkarị mma karịa nke usoro sulfuric acid na-emepụta.Nke a bụ n'ihi na akụrụngwa titanium tetrachloride eji eme ihe na-emepụta titanium dioxide site na usoro chloride ka agbazere ma mee ka ọ dị ọcha, na ọdịnaya adịghị ọcha nke ya dị ntakịrị, ebe usoro sulfuric acid na-eji ihe ndị na-emepụta ihe nwere nnukwu adịghị ọcha, nke nwere ike naanị. ewepụ ya site na ịsacha na usoro ịcha ọcha.

Titanium dioxide bụ ụmụ irighiri ihe dị mma nke nwere nnukwu akụkụ elu ya na ike elu dị elu.Ọ dị mfe ikpokọta n'etiti irighiri ihe ma sie ike ịgbasa na mkpuchi.Mgbasa na-adịghị mma nke titanium dioxide ga-emetụta kpọmkwem ihe ndị na-ahụ anya ya dị ka mbelata agba, ike na-ezo na gloss elu na mkpuchi ahụ, ma na-emetụtakwa nkwụsi ike nke nchekwa, mmiri mmiri, ọkwa ọkwa, mkpuchi mkpuchi, na mgbochi corrosion nke mkpuchi.Ngwa ngwa dị ka eletriki conductivity na conductivity ga-emetụtakwa mmepụta ego nke mkpuchi, n'ihi na ike oriri nke egweri na mgbasa ọrụ dị elu, na-aza ajụjụ maka ọtụtụ n'ime ngụkọta ike oriri nke mkpuchi n'ichepụta usoro, na ọnwụ nke akụrụngwa dị ukwuu. .
Ọchịchọ titanium dioxide na-arị elu n'afọ a, ọkachasị maka titanium dioxide ejiri na ụlọ ọrụ ụgbọ elu lithium-ion, nke ka dabere na mbubata.Dị ka mgbada nke titanium dioxide, ihe mkpuchi na-emetụta oke ifufe nke gburugburu ebe obibi, na ọnụ ọgụgụ dị ukwuu nke obere na obere ụlọ ọrụ emechiela.N'ọdịnihu, ọnụ ọgụgụ nke titanium dioxide na ahịa mkpuchi ga-ebelatakwa.
