Ka hoʻomaopopo ʻana i nā ʻokoʻa ma waena o Rutile, Anatase, a me Brookite: wehe i nā mea huna o Titanium Dioxide

Hoʻolauna:

Titanium dioxide (TiO2) ʻo ia kekahi o nā mea maʻalahi a hoʻohana nui ʻia i nā ʻoihana like ʻole, me ka pena a me ka uhi, nā mea hoʻonaninani, a me nā meaʻai. ʻEkolu mau hale aniani nui ma ka ʻohana TiO2:rutile anatase a me brookite. He mea koʻikoʻi ka hoʻomaopopo ʻana i ka ʻokoʻa ma waena o kēia mau hale i ka hoʻohana ʻana i kā lākou mau waiwai kūʻokoʻa a wehe i ko lākou hiki. Ma kēia blog, e nānā pono mākou i nā waiwai a me nā noi o rutile, anatase, a me brookite, e hōʻike ana i kēia mau ʻano hoihoi ʻekolu o ka titanium dioxide.

1. Rutile Tio2:

ʻO Rutile ka ʻano nui a paʻa o ka titanium dioxide. Hōʻike ʻia ʻo ia e kona ʻano kristal tetragonal, i loaʻa i nā octahedrons paʻa paʻa. Hāʻawi kēia hoʻonohonoho kristal i ka rutile maikaʻi loa i ka pale ʻana i ka radiation UV, e hana ana ia i kahi koho maikaʻi loa no ka hoʻokumu ʻana i ka sunscreen a me nā uhi pale UV.Rutile Tio2Hoʻonui pū ka huahelu refractive kiʻekiʻe i kona opacity a me ka ʻōlinolino, i mea kūpono no ka hana ʻana i nā pena kiʻekiʻe a me nā inika paʻi. Eia kekahi, ma muli o kona kūpaʻa kemika kiʻekiʻe, loaʻa iā Rutile Tio2 nā noi i nā ʻōnaehana kākoʻo catalyst, ceramics, a me nā polokalamu optical.

2. Anatase Tio2:

ʻO Anatase kekahi ʻano crystalline maʻamau o ka titanium dioxide a he ʻano tetragonal maʻalahi. Hoʻohālikelike ʻia me rutile,Anatase Tio2he haʻahaʻa haʻahaʻa a ʻoi aku ka nui o ka ʻili, e hāʻawi ana i ka hana photocatalytic kiʻekiʻe. No laila, hoʻohana nui ʻia i nā noi photocatalytic e like me ka hoʻomaʻemaʻe wai a me ka ea, ka hoʻomaʻemaʻe ponoʻī ʻana, a me ka mālama ʻana i ka wai. Hoʻohana ʻia ʻo Anatase ma ke ʻano he mea keʻokeʻo i ka hana pepa a ma ke ʻano he kākoʻo catalyst i nā hopena kemika. Eia kekahi, ʻo kāna mau waiwai uila e kūpono ai no ka hana ʻana i nā cell solar dye-sensitized a me nā sensor.

3. Brookite Tio2:

ʻO Brookite ka mea liʻiliʻi loa o ka titanium dioxide a loaʻa iā ia kahi ʻano kristal orthorhombic i ʻokoʻa loa mai nā hale tetragonal o rutile a me anatase. Loaʻa pinepine ʻo Brookite me nā ʻano ʻelua ʻē aʻe a loaʻa kekahi mau hiʻohiʻona hui. ʻOi aku ka kiʻekiʻe o kāna hana catalytic ma mua o ka rutile akā ʻoi aku ka haʻahaʻa ma mua o ka anatase, e hoʻohana pono ai i kekahi mau noi cell solar. Hoʻohui ʻia, ʻo ke ʻano kristal kūʻokoʻa o brookite e ʻae iā ia e hoʻohana ʻia ma ke ʻano he mineral specimen i nā mea nani ma muli o kona ʻano kakaʻikahi a kū hoʻokahi.

Ka hopena:

I ka hōʻuluʻulu ʻana, ʻo nā mea ʻekolu o ka rutile, anatase a me brookite he mau ʻano ʻano like ʻole a me nā waiwai, a loaʻa i kēlā me kēia me kona pono ponoʻī a me nā noi. Mai ka pale UV a hiki i ka photocatalysis a ʻoi aku, kēia mau ʻano otitanium dioxidehe kuleana koʻikoʻi i loko o nā ʻoihana like ʻole, e koi ana i nā palena o ka hana hou a hoʻomaikaʻi i ko mākou ola i kēlā me kēia lā.

Ma ka hoʻomaopopo ʻana i nā waiwai a me nā noi o rutile, anatase a me brookite, hiki i nā mea noiʻi a me nā ʻoihana ke hoʻoholo i ka hoʻoholo ʻana i ke koho ʻana i ke ʻano o ka titanium dioxide i kūpono i kā lākou mau pono kikoʻī, e hōʻoia i ka hana maikaʻi loa a me nā hopena i manaʻo ʻia.
