He aha ka mea e hoʻohana ʻia ai ka Titanium Dioxide?
Nā wahi noi kuʻuna
1. Nā Pigments a me nā mea hūnā
ʻOihana uhi: Ma ke ʻano he pigment keʻokeʻo, hāʻawi ia i ke keʻokeʻo kiʻekiʻe (L>98) a me ka mana hūnā ikaika (>95%) i ka uhi ʻoiai e hoʻomaikaʻi ana i ke kūpaʻa ʻana i ka wā (hala i ka hoʻāʻo QUV-A 2000h).
Nā palakiko a me ka hana pepa: Hoʻonui i ka opacity (>90%) a me nā waiwai anti-melemele o nā huahana palakiko; hoʻohana ʻia no ka mālama ʻana i ka ʻili o ka pepa kiʻekiʻe e hoʻomaikaʻi i ka ʻālohilohi a me ka hiki ke paʻi ʻia.
2. Nā keramika a me ka enamel
Hoʻololi ʻana i ka glaze: Ma ke ʻano he mea pale kukui a me ka mea hoʻokeʻokeʻo, hiki iā ia ke hoʻomaikaʻi i ka paʻakikī (paʻakikī Mohs ≥ 6), ka ʻōlinolino (reflectivity > 85%) a me ke kūpaʻa waikawa (kūʻē i ka 10% HCl solution > 24h) o ka ʻili glaze.
3. Nā kemika o kēlā me kēia lā a me ka meaʻai
Nā huahana pale lā: Hāʻawi i ka palekana kino o ka lā ma o ka hoʻopuehu ʻana i nā kukuna ultraviolet (nā kāʻei UVA/UVB), a hiki i ka nano-scale TiO₂ (ka nui o nā ʻāpana ≤100nm) ke pale aku i ka ʻili pipili.
Mea hoʻohui meaʻai: Ma ke ʻano he pigment keʻokeʻo ʻawaʻawa ʻole (kūlike me ka FDA 21CFR73.575), hoʻohana ʻia ia no ka hoʻokeʻokeʻo ʻana i nā candies, nā huahana waiū, a pēlā aku.

Nā wahi noi e kū mai ana
1. Hoʻomalu ʻana i ke kaiapuni
Ka hōʻino ʻana o ka palakiko: Hiki ke hōʻino ʻia ka mea titanium dioxide lana ma lalo o nā kūlana kūlike ʻole ma o ka papa hydrophobic o ka ʻili me ka ʻole o ka pono no ka mālama mua ʻana o ka waikawa/alkali ikaika, e hoʻonui ana i ka pono o ka hoʻoheheʻe ʻana o nā palakiko polyethylene i nā manawa he nui, me ka ethanol e helu ana no 40% o ka huahana.
Hoʻomaʻemaʻe ea: Hiki i ka photocatalyst nano-TiO₂ ikaika 5nm ke hoʻoheheʻe i nā mea haumia e like me formaldehyde a me benzene (ka helu degradation > 98%), a hoʻonui ʻia kāna spectrum hana i ka pae kukui ʻike ʻia (ma luna o 400nm).
2. ʻenehana ikehu
Ka hoʻokaʻawale ʻana o ka wai photocatalytic e hana i ka hydrogen: Hoʻonui ka rutile TiO₂ i hoʻopili ʻia me ka scandium i ka pono o ka hoʻokaʻawale ʻana o ka uku photogenerated ma 200 mau manawa, a ʻo ka nui o ka hana hydrogen he 15 mau manawa o nā mea kuʻuna (ma lalo o ka lā simulated).
Nā mea ikehu hou: hoʻohana ʻia no ka uhi ʻana o ka electrode maikaʻi o ka pākahi lithium e kāohi i nā hopena ʻaoʻao electrode a hoʻomaikaʻi i ke kūpaʻa o ke kaʻina hana (>4000 manawa @80% SOH).
3. Hoʻololi mea hana
Uhi antibacterial: Komo ka Nano-titanium sol i loko o ka substrate e hana i kahi papa mānoanoa, me ka helu pepehi o >98% e kūʻē iā E. coli a me nā bacteria ʻē aʻe, a me ka hōʻemi ʻana o ka hana o <5% ma hope o ka ʻelemakule ʻana no 5 mau makahiki.
Nā mea hana hale kūpaʻa loa i ka wā: Hoʻonui ka TiO₂ i hoʻopili ʻia me ka cerium honua laha ʻole i ke kūpaʻa UV o nā uhi paia o waho (ka helu pale UVA > 99%) a hoʻomaikaʻi i ke kūpaʻa hau-thaw ma 50%.
Uhi ʻōniʻoniʻo: Hoʻohana ʻia nā waiwai kuhikuhi refractive kiʻekiʻe (nd=1.75-2.20) no nā uhi anti-reflection e hōʻemi i ka pohō optical i nā mea laser (<0.1dB/km).
4. ʻOihana Hana Kūikawā
Hana kemika: Ma ke ʻano he mea hoʻouluulu olefin epoxidation, ʻo ka helu hoʻololi he >95%; i loko o ka ʻōnaehana hana hydrogen hoʻokaʻawale wai photocatalytic, ua hui pū ʻia me CdS e hoʻomaikaʻi i ka pono hana hydrogen.

Palekana a me ka Hoʻokō
Ka hoʻokaʻawale ʻana i ka halihali: Nā waiwai ʻino ʻole (ʻAʻOLE HŌʻINO)
Palapala hōʻoia kaiapuni:
- RoHS 3.0 (2015/863/EU) ʻAʻole i ʻike ʻia nā metala kaumaha

Palekana hana: palena OSHA TWA 5mg/m³ (lepo)
Nā Mālama
Pono nā hana nanopowder i ka pale hanu N95 (kūlike me ISO 13137)
No nā noi wela kiʻekiʻe, ua ʻōlelo ʻia e hoʻohana i nā ipu hoʻoheheʻe corundum
Pono nā huahana papa meaʻai/lāʻau lapaʻau e hāʻawi i nā palapala hoʻokō COA a me FDA

Hoʻokumu ʻia ka wehewehe ʻana ma luna nei ma nā ʻano laulā o ka titanium dioxide. No nā hoʻonā noi kikoʻī a me nā palena, e ʻoluʻolu e nānā i ka huahana COA (hōʻike nānā maikaʻi) a me ka faila MSDS.
E kākau i kāu leka ma aneʻi a hoʻouna mai iā mākou
