Titanium Dioxide

ʻO ka Titanium dioxide (TiO2) he puaʻa keʻokeʻo i hoʻohana nui ʻia i nā ʻoihana like ʻole ma muli o kāna mau waiwai kūʻokoʻa. Eia kahi hiʻohiʻona o ka titanium dioxide, kona mau waiwai, a me kāna mau noi like ʻole:

1. Ka Hoʻohui Kemika: ʻO ka Titanium dioxide he oxide kūlohelohe o ka titanium me ke ʻano kemika TiO2. Aia ia ma nā ʻano crystalline, me ka rutile a me ka anatase ka mea maʻamau. ʻIke ʻia ʻo Rutile TiO2 no kāna ʻōlelo kuhikuhi refractive kiʻekiʻe a me ka opacity, ʻoiai ʻo anatase TiO2 e hōʻike ana i ka hana photocatalytic kiʻekiʻe.
2. Pigment Keʻokeʻo: ʻO kekahi o ka hoʻohana mua ʻana o ka titanium dioxide ma ke ʻano he puaʻa keʻokeʻo i loko o nā pena, nā uhi, nā plastics, a me ka pepa. Hāʻawi ia i ka ʻōlinolino, opacity, a me ke keʻokeʻo i kēia mau mea, e ʻoluʻolu a hoʻonui i ko lākou uhi a me ka mana huna. ʻOi aku ka maikaʻi o ka Titanium dioxide ma mua o nā puaʻa keʻokeʻo ʻē aʻe ma muli o kāna mau waiwai hoʻopuʻi māmā maikaʻi a me ke kūpaʻa ʻana i ka discoloration.
3. UV Absorber a me Sunscreen: Hoʻohana nui ʻia ka Titanium dioxide ma ke ʻano he UV absorber i nā sunscreens a me nā huahana cosmetic. Hana ʻo ia ma ke ʻano he pale lā kino ma ka hoʻohālikelike ʻana a me ka hoʻopuehu ʻana i ka radiation UV, ma laila e pale ai i ka ʻili mai nā hopena pōʻino e like me ka sunburn, ka wā ʻelemakule, a me ka maʻi maʻi ʻili. Hoʻohana pinepine ʻia nā ʻāpana nanoscale titanium dioxide i nā hoʻoheheʻe ʻana i ka lā no ko lākou ʻike a me ka pale UV ākea ākea.
4. Photocatalyst: ʻO kekahi mau ʻano o ka titanium dioxide, ʻoi aku ka anatase TiO2, hōʻike i ka hana photocatalytic ke ʻike ʻia i ke kukui ultraviolet. Hiki i kēia waiwai ke hiki i ka titanium dioxide ke hoʻopololei i nā hopena kemika like ʻole, e like me ka decomposition o nā mea pollutants organik a me ka sterilization o nā ʻili. Hoʻohana ʻia ka photocatalytic titanium dioxide i nā uhi hoʻomaʻemaʻe ponoʻī, nā ʻōnaehana hoʻomaʻemaʻe ea, a me nā noi mālama wai.
5. Mea Hoʻohui Meaʻai: Ua ʻae ʻia ka Titanium dioxide ma ke ʻano he meaʻai meaʻai (E171) e nā hui hoʻoponopono e like me ka FDA a me ka European Food Safety Authority (EFSA). Hoʻohana maʻamau ia i nā huahana meaʻai, e like me ka confectionery, nā mea i kālua ʻia, a me nā huahana waiu, ma ke ʻano he mea keʻokeʻo a me ka opacifier. Kōkua ʻo Titanium dioxide i ka hoʻomaikaʻi ʻana i ke ʻano a me ke ʻano o nā meaʻai, e ʻoi aku ka maikaʻi o ka nānā ʻana i nā mea kūʻai.
6. Kākoʻo Catalyst: Hana ʻia ka Titanium dioxide ma ke ʻano he kākoʻo catalyst i nā kaʻina kemika like ʻole, me ka catalysis heterogeneous a me ka hoʻoponopono ʻana i ke kaiapuni. Hāʻawi ia i kahi ʻāpana kiʻekiʻe a me ke kākoʻo paʻa paʻa no nā wahi hana catalytic, e hoʻomaʻamaʻa i nā hopena kemika kūpono a me ka hoʻohaumia ʻana i ka pollutant. Hoʻohana ʻia nā catalysts kākoʻo Titanium dioxide i nā noi e like me ka hoʻomaʻamaʻa ʻana i nā kaʻa, ka hana hydrogen, a me ka mālama wai ʻino.
7. Electroceramics: Hoʻohana ʻia ka Titanium dioxide i ka hana ʻana i nā mea electroceramic, e like me nā capacitors, varistors, a me nā mea ʻike, ma muli o kāna mau waiwai dielectric a me semiconductor. Hana ʻo ia ma ke ʻano he mea dielectric kiʻekiʻe-k i loko o nā capacitors, hiki ke mālama i ka ikehu uila, a ma ke ʻano he mea koʻikoʻi kinoea i loko o nā mea ʻike no ka ʻike ʻana i nā kinoea a me nā mea hoʻohuihui kūlohelohe.

I ka hōʻuluʻulu ʻana, ʻo ka titanium dioxide he mea maʻalahi me ka nui o nā noi, e like me ka puaʻa keʻokeʻo, UV absorber, photocatalyst, mea hoʻohui meaʻai, kākoʻo catalyst, a me nā mea electroceramic. ʻO kāna hui pū ʻana o nā waiwai he mea nui ia i nā ʻoihana e like me nā pena a me nā uhi, nā mea hoʻonaninani, ka hoʻoponopono ʻana i ke kaiapuni, nā meaʻai, nā uila, a me ka mālama olakino.
