He aha te titanium dioxide?
Ko te waahanga matua o te titanium dioxide ko te TIO2, he poaka matū pararopi nui i te ahua o te totoka ma, te paura ranei. Kare he paitini, he maamaa me te kanapa, ka kiia ko te poaka ma pai rawa atu hei whakapai ake i te ma. Kei te whakamahia nuitia i roto i nga ahumahi penei i te paninga, te kirihou, te rapa, te pepa, te mangumangu, te karaehe, te karaihe, me era atu.
Ⅰ.Hoahoa mekameka ahumahi Titanium dioxide:
（1）Ko te whakarunga o te mekameka ahumahi titanium dioxide he rauemi mata, tae atu ki te ilmenite, titanium concentrate, rutile, aha atu;
（2）Ko te awa waenga e pa ana ki nga hua titanium dioxide.
（3）Ko te taha whakararo te waahi tono mo te titanium dioxide.Kei te whakamahia nuitia te titanium dioxide i roto i nga momo mara penei i te paninga, te kirihou, te hanga pepa, te mangumangu, te rapa, me era atu.
Ⅱ.Ko te hanganga karaihe o te titanium dioxide:
Ko te titanium dioxide he momo puhui polymorphous, e toru nga ahua kiriata noa i roto i te taiao, ara te anatase, rutile me te brookite.
Ko te rutile me te anatase no te punaha tioata tetragonal, he pumau i raro i te pāmahana noa; Ko te brookite no te punaha tioata orthorhombic, me te hanganga karaihe koretake, no reira he iti noa te uara o te umanga i naianei.
I roto i nga hanganga e toru, ko te waahanga rutile te mea tino pumau. Ko te wahanga Anatase ka huri korekore ki te wahanga rutile i runga ake i te 900°C, ko te wahanga brookite ka huri korekore ki te wahanga rutile i runga ake i te 650°C.
（1）Wahanga Rutile Titanium Dioxide
I roto i te wahanga rutile titanium dioxide, kei te waenganui o nga ngota titanium titanium, a e ono nga ngota hāora kei nga kokonga o te titanium-oxygen octahedron. Ka hono ia octahedron ki te 10 octahedron a tawhio noa (tae atu ki te waru nga poutoko tiri me nga tapa tiri e rua), ka hangai e rua ngota ngota TiO2 hei pūtau wae.
Hoahoa hoahoa o te pūtau karaihe o te wahanga rutile titanium dioxide (maui)
Ko te tikanga hononga o te titanium oxide octahedron (matau)
（2）Wāhanga anatase titanium hauhā
I roto i te wahanga anatase titanium dioxide, ka hono ia titanium-oxygen octahedron ki te 8 octahedron a tawhio noa (4 nga tapa tiritiri me te 4 tiritiri poutokonga), ka hangai e 4 ngota ngota TiO2 hei pūtau wae.

Ko te tikanga hononga o te titanium oxide octahedron (matau)
Ⅲ. Nga Tikanga Whakaritenga mo te Titanium Dioxide:
Ko te tukanga whakaputa o te hauhā titanium te nuinga kei roto te tukanga waikawa sulfuric me te tukanga chlorination.
（1）Tukanga waikawa pungatara
Ko te tukanga waikawa pungatara o te hanga titanium dioxide ko te tauhohenga acidolysis o te paura rino titanium me te waikawa sulfuric kukū hei whakaputa i te titanium sulfate, katahi ka whakamaarama hei whakaputa i te waikawa metatitanic. I muri i te whakamaarama me te kuru, ka whiwhi nga hua titanium dioxide. Ka taea e tenei tikanga te whakaputa anatase me te rutile titanium dioxide.
（2）Tukanga chlorination
Ko te mahi whakamaarama o te whakangao titanium dioxide ko te whakaranu i te rutile, te paura para titanium teitei ranei me te coke katahi ka kawe i te whakamaarama i te pāmahana teitei hei whakaputa i te tetrachloride titanium. I muri i te hauhautanga teitei, ka whiwhi te hua titanium dioxide na roto i te tātari, te horoi wai, te whakamaroke, me te kuru. Ka taea e te mahi whakamaarama o te hanga titanium dioxide te whakaputa hua rutile anake.
Me pehea te wehewehe i te pono o te titanium dioxide?
I. Tikanga Tinana:
（1）Ko te tikanga ngawari ko te whakataurite i te kakano ma te pa. Ko te titanium dioxide rūpahu ka ngawari ake, ko te titanium dioxide ka kaha ake.
（2）Ma te horoi ki te wai, mena ka maka e koe etahi titanium dioxide ki to ringaringa, ka ngawari te horoi i te mea teka, engari ko te mea pono kaore e ngawari ki te horoi.
（3）Tangohia he kapu wai ma ka makahia te titanium dioxide ki roto. Ko te mea e rewa ana ki te mata he pono, ko te mea e tau ana ki raro he rūpahu (kaore pea tenei tikanga e pai mo nga hua kua whakahohehia, kua whakarereketia ranei).
（4）Tirohia tona memehatanga ki te wai. Ko te tikanga, ka whakarewahia te titanium dioxide ki te wai (haunga te titanium dioxide i hangaia mo te kirihou, te waituhi, me etahi titanium dioxide, e kore e rewa ki te wai).
II. Tikanga matū:
(1) Mēnā ka tāpirihia te paura konupūmā: Ko te tāpiri i te waikawa pūhaumāota ka puta he tauhohenga kaha me te tangi tiiri, me te hanga o te maha o nga mirumiru (na te mea ka tauhohe te konupūmā pākawa waro ki te waikawa ki te whakaputa hauhā).
(2) Mēnā ka tāpirihia te lithopone: Ko te taapiri i te waikawa sulfuric waimeha, te waikawa pūhaumāota ranei ka puta he haunga hua manu.
(3) Mēnā he hauwai te tauira, ko te tāpiri i te waikawa pūhaumāota e kore e puta he tauhohenga. Heoi, i muri i te whakamakuku ki te waiwaro katahi ka taapirihia te waikawa maaota, mena ka puta he mirumiru, ka tohu kei roto i te tauira te paura konupūmā warokawa kua pania.
III. E rua ano nga tikanga pai:
(1) Ma te whakamahi i te ahua ano o te PP + 30% GF + 5% PP-G-MAH + 0.5% titanium dioxide paura, ko te iti ake o te kaha o te rauemi hua, ko te tino pono o te titanium dioxide (rutile).
(2) Tīpakohia he kapia maramara, penei i te ABS maramara me te 0.5% titanium dioxide paura kua tapirihia. Te ine i tana whakawhiti marama. Ko te iti ake o te whakawhiti marama, ka nui ake te pono o te paura titanium dioxide.
