He aha te hauhā titanium?
Ko te wāhanga matua o te hauhā titanium ko te TIO2, he tae matū kore-waro nui i te āhua o te totoka mā, te paura rānei. Kāore he paitini, he mā me te kanapa teitei, ā, e kiia ana ko te tae mā pai rawa atu hei whakapai ake i te mā o ngā rauemi. He whānuitia te whakamahinga i roto i ngā ahumahi pēnei i te paninga, te kirihou, te rapa, te pepa, te waituhi, te uku, te karāhe, me ētahi atu.
Ⅰ.Te hoahoa mekameka ahumahi titanium dioxide:
（1Ko te wāhanga whakarunga o te mekameka ahumahi titanium dioxide he rauemi mata, tae atu ki te ilmenite, te titanium concentrate, te rutile, me ētahi atu;
（2）Ko te midstream e pā ana ki ngā hua titanium dioxide.
(3) Ko te wāhanga o raro ko te mara tono o te hauhā titanium.E whakamahia whānuitia ana te hauhā titanium i roto i ngā momo mara pērā i te paninga, te kirihou, te hanga pepa, te waituhi, te rapa, me ētahi atu.
Ⅱ. Te hanganga karaihe o te hauhā titanium:
He momo matū maha-āhua te hauhā titanium, e toru ngā āhua tioata noa i te taiao, arā, te anatase, te rutile me te brookite.
Nō te pūnaha tioata tetragonal te rutile me te anatase, e pumau ana i raro i te pāmahana noa; nō te pūnaha tioata orthorhombic te brookite, he hanganga tioata kore pumau, nō reira he iti noa te uara mahi i roto i te ahumahi i tēnei wā.
I roto i ngā hanganga e toru, ko te āhua rutile te mea tino pumau. Ka huri te āhua anatase hei āhua rutile i runga ake i te 900°C, ko te āhua brookite ia ka huri hei āhua rutile i runga ake i te 650°C.
（1）Hauora hauotaita wāhanga rutile
I roto i te hauhā titanium āhua rutile, kei waenganui o te whatunga tioata ngā ngota Ti, ā, e ono ngā ngota hāora kei ngā kokonga o te octahedron titanium-hāora. E hono ana ia octahedron ki ngā octahedron e 10 e karapoti ana (tae atu ki ngā pito e waru e tiritiri ana me ngā tapa e rua e tiritiri ana), ā, e rua ngā ngota TiO2 e hanga ana i tētahi pūtau kotahi.

Te tikanga hononga o te octahedron titanium oxide (matau)
（2）Te hauhā titanium wāhanga anatase
I roto i te hauhā titanium wāhanga anatase, ka honoa ia octahedron titanium-hāora ki ngā octahedron e 8 e karapoti ana (4 ngā tapa tiritahi me ngā pito tiritahi e 4), ā, ka hangaia e ngā ngota TiO2 e 4 he pūtau kotahi.

Ⅲ. Ngā Tikanga Whakarite mō te Taihauāwhio:
Ko te tukanga whakaputa o te hauhā titanium te nuinga o te wā ko te tukanga waikawa whanariki me te tukanga whakapūkara.
（1）Te tukanga waikawa whanariki
Ko te tukanga whakaputa waikawa whanariki mō te whakaputanga o te hauhā titanium ko te tauhohenga waikawa o te paura rino titanium me te waikawa whanariki kukū hei whakaputa i te hauhā titanium, ka whakapūkaratia hei whakaputa i te waikawa metatitanic. I muri i te whakapūkara me te kuru, ka puta mai ngā hua hauhā titanium. Ka taea e tēnei tikanga te whakaputa i te hauhā titanium anatase me te rutile.
（2）Te tukanga whakakōkōwai
Ko te tukanga whakakōroi i te hanga titanium hauhā ko te whakaranu i te paura rutile, te paura titanium-teitei rānei ki te coke, kātahi ka whakahaere i te whakakōroi i te pāmahana teitei hei whakaputa i te titanium tetrachloride. I muri i te waikura pāmahana teitei, ka whiwhihia te hua titanium hauhā mā te tātari, te horoi wai, te whakamaroke, me te kuru. Ko te tukanga whakakōroi i te hanga titanium hauhā ka taea anake te whakaputa i ngā hua rutile.
Me pēhea te wehewehe i te pono o te titanium dioxide?
I. Ngā Tikanga Ā-tinana:
（1）Ko te tikanga māmā rawa ko te whakatairite i te kakano mā te pā. He maeneene ake te āhua o te hauhā titanium rūpahu, engari he taratara ake te āhua o te hauhā titanium tūturu.
（2）Mā te horoi ki te wai, ki te pania e koe he hauhā titanium ki tō ringaringa, ka ngāwari te horoi atu i te mea rūpahu, ko te mea tūturu ia kāore e ngāwari te horoi atu.
（3）Tangohia he kapu wai mā, ka maturuturu te hauhā titanium ki roto. Ko te mea e mānu ana ki te mata he mea tūturu, ko te mea e tau ana ki raro he mea rūpahu (tērā pea kāore tēnei tikanga e mahi mō ngā hua kua whakahohehia, kua whakarerekētia rānei).
（4）Tirohia tōna wairewatanga ki te wai. I te nuinga o te wā, ka wairewa te hauhā titanium ki te wai (haunga te hauhā titanium i hangaia mō ngā kirihou, ngā waituhi, me ētahi hauhā titanium hangai, kāore e wairewa ki te wai).
II. Ngā tikanga matū:
(1) Mēnā ka tāpirihia te paura konupūmā: Mā te tāpiri i te waikawa hauwaiora ka puta he tauhohenga kaha me te tangi tioriori, me te whakaputanga o te tini o ngā mirumiru (nā te mea ka tauhohe te konupūmā kāponāte ki te waikawa hei whakaputa i te hauhā waro).
(2) Mēnā ka tāpirihia he lithopone: Mā te tāpiri i te waikawa whanariki waimeha, te waikawa hauwaiora rānei ka puta he haunga hua pirau.
(3) Mena he wai-whakahē te tauira, kāore e puta he tauhohenga mena ka tāpirihia he waikawa hauwaiora. Heoi, i muri i te whakamakuku ki te etanoru, kātahi ka tāpirihia he waikawa hauwaiora, mena ka puta he mirumiru, ka whakaatu kei roto i te tauira he paura konupūmā kāponāte kua pania.
III. E rua atu anō ngā tikanga pai:
(1) Mā te whakamahi i te tātai kotahi o PP + 30% GF + 5% PP-G-MAH + 0.5% paura hauhā titanium, ka iti ake te kaha o te rauemi ka puta, ka pono ake te hauhā titanium (rutile).
(2) Kōwhiria he kapia mārama, pērā i te ABS mārama me te 0.5% paura titanium hauhā i tāpirihia. Inehia tōna whakawhiti mārama. Ko te iti o te whakawhiti mārama, ko te pono ake o te paura titanium hauhā.
