He aha te whakamahinga o te Titanium Dioxide?
Ngā wāhi tono tuku iho
1. Ngā tae me ngā mea huna
Te umanga paninga: Hei tae mā, ka hoatu he mā nui (L>98) me te kaha huna kaha (>95%) ki te paninga, me te whakapai ake i te ātete ki te huarere (kua paahitia te whakamātautau QUV-A 2000h).
Kirihou me te hanga pepa: Whakanuia ake te mārama (>90%) me ngā āhuatanga ārai-kōwhai o ngā hua kirihou; whakamahia mō te maimoatanga mata o te pepa kounga teitei hei whakapai ake i te kanapa me te āheinga tā.
2. Ngā uku me te enamel
Te whakarerekētanga o te karāhe: Hei ārai mārama, hei whakama hoki i te kiri, ka taea te whakapai ake i te pakeketanga (pakaritanga Mohs ≥ 6), te kanapatanga (whakaata > 85%) me te ātete waikawa (ātete ki te otinga HCl 10% > 24h) o te mata o te karāhe.
3. Ngā matū me ngā kai o ia rā
Ngā hua ārai rā: Ka whakarato i te tiaki tinana o te rā mā te titaritari i ngā hihi ultraviolet (ngā roopu UVA/UVB), ā, ka taea e te TiO₂ nano-tauine (rahi matūriki ≤100nm) te karo i te kiri piri.
Tāpiri kai: Hei tae mā kore-paitini (e tutuki ana i te FDA 21CFR73.575), e whakamahia ana hei whakama i ngā monamona, ngā hua miraka, me ētahi atu.

Ngā wāhi tono hou
1. Te whakahaere taiao
Te pirau kirihou: Ka taea te pirau i te rauemi titanium dioxide e mānu ana i raro i ngā āhuatanga kūpapa mā roto i te paparanga hydrophobic o te mata, me te kore e hiahiatia he maimoatanga waikawa/kawakore kaha i mua, ka whakanui ake i te whai huatanga pirau o ngā kirihou polyethylene kia maha ngā wā, me te 40% o te hua ko te etanoru.
Te purenga o te hau: Ka taea e te whakakorikori whakaahua nano-TiO₂ kaha 5nm te wawahi i ngā poke pēnei i te formaldehyde me te benzene (te tere pirau > 98%), ā, ka toro atu tōna whānuitanga mahi ki te awhi mārama e kitea ana (neke atu i te 400nm).
2. Hangarau Pūngao
Te wehenga wai whakaahua-whakakorikori hei whakaputa hauwai: Mā te rutile TiO₂ kua tāpirihia ki te scandium ka piki ake te whai huatanga o te wehenga utu whakaahua-whakaputa mā te 200 ngā wā, ā, ko te tere whakaputa hauwai he 15 ngā wā i tērā o ngā rauemi tuku iho (i raro i te hihi o te rā whakaata).
Ngā rauemi pūngao hou: e whakamahia ana mō te paninga hiko pai o te pākahiko lithium hei aukati i ngā tauhohenga taha hiko me te whakapai ake i te pumau o te huringa (>4000 ngā wā @80% SOH).
3. Te whakarerekētanga rauemi mahi
Paninga ārai-huakita: Ka uru te konutai nano-titanium ki roto i te papa hei hanga i tētahi paparanga matotoru, me te tere whakamate o te >98% ki te E. coli me ētahi atu huakita, ā, ka heke te mahi o te <5% i muri i te pakeketanga mō ngā tau e 5.
Ngā rauemi hanga tino ātete ki te huarere: Ka whakarei ake te TiO₂ kua pania ki te cerium onge i te ātete UV o ngā paninga pakitara o waho (te auau tiaki UVA > 99%) me te whakapai ake i te ātete huka-rewa mā te 50%.
Paninga whatu: Ka whakamahia ngā āhuatanga taupū whakaata teitei (nd=1.75-2.20) mō ngā paninga ārai-whakaata hei whakaiti i te ngaronga whatu i roto i ngā taputapu taiaho (<0.1dB/km).
4. Whakakorikori Ahumahi Motuhake
Te Hanganga Matū: Hei whakakorikori epoxidation olefin, ko te tere tahuritanga he >95%; i roto i te pūnaha whakaputa hauwai wehewehe wai photocatalytic, ka honoa ki te CdS hei whakapai ake i te whai huatanga o te whakaputa hauwai.
