He aha ka Titanium Dioxide i hoʻohana ʻia no

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

1. Pigment i loko o ka pena a me ka pena: ʻO Titanium dioxide kekahi o nā puaʻa keʻokeʻo maʻamau i hoʻohana ʻia i loko o nā pena, nā uhi, a me nā plastics ma muli o kona opacity maikaʻi loa, ʻōlinolino, a keʻokeʻo. Hāʻawi ia i ka mana huna ʻoi aku ka maikaʻi, hiki ke hana i nā hoʻopau kiʻekiʻe me nā kala ʻoi. Hoʻohana ʻia ʻo TiO2 i nā pena i loko a me waho, nā uhi kaʻa, nā hale kūkulu hale, a me nā uhi ʻoihana.

2. Palekana UV i nā Sunscreens: Ma ka ʻoihana hoʻonaninani a me ka ʻoihana mālama pilikino, hoʻohana ʻia ka titanium dioxide ma ke ʻano he kānana UV i nā sunscreens a me nā huahana skincare. Kōkua ia i ka pale ʻana i ka ʻili mai ka radiation ultraviolet (UV) pōʻino ma ka noʻonoʻo ʻana a me ka hoʻopuehu ʻana i nā kukuna UV, pēlā e pale ai i ka lā a me ka hōʻemi ʻana i ka hopena o ka maʻi maʻi ʻili a me ka wā ʻelemakule.

3. Mea Hoʻohui Meaʻai: Ua ʻae ʻia ka Titanium dioxide ma ke ʻano he mea hoʻohui meaʻai (E171) ma nā ʻāina he nui a hoʻohana ʻia ma ke ʻano he mea hoʻomaʻemaʻe keʻokeʻo i nā huahana meaʻai e like me nā candies, chewing gum, dairy products, and confectionery. Hāʻawi ia i kahi kala keʻokeʻo keʻokeʻo a hoʻonui i ke ʻano o nā meaʻai.

4. Photocatalysis: Hōʻike ka Titanium dioxide i nā waiwai photocatalytic, ʻo ia hoʻi, hiki iā ia ke hoʻolalelale i kekahi mau hopena kemika i mua o ka mālamalama. Hoʻohana ʻia kēia waiwai i nā noi kaiapuni like ʻole, e like me ka hoʻomaʻemaʻe ʻana i ka ea a me ka wai, nā ʻili hoʻomaʻemaʻe ponoʻī, a me nā uhi antibacterial. Hiki i nā uhi uhi Photocatalytic TiO2 ke wāwahi i nā mea haumia organik a me nā microorganism pōʻino ke ʻike ʻia i ke kukui ultraviolet.

5. ʻO nā ʻanuʻu Ceramic a me nā Pigments: Ma ka ʻoihana ceramics, hoʻohana ʻia ka titanium dioxide e like me ka opacifier glaze a me ka puaʻa i loko o nā tile ceramic, tableware, sanitaryware, a me nā mea hoʻonaninani. Hāʻawi ia i ka mālamalama a me ka opacity i nā huahana ceramic, hoʻonui i kā lākou hoʻopiʻi nani, a hoʻomaikaʻi i ko lākou kūpaʻa a me ke kūpaʻa kemika.

6. Pepa a me ka Paʻi Paʻi: Hoʻohana ʻia ka Titanium dioxide ma ke ʻano he mea hoʻopiha a me ka puaʻa uhi i ke kaʻina hana pepa e hoʻomaikaʻi ai i ka keʻokeʻo pepa, opacity, a me ka paʻi. Hoʻohana ʻia ia i ka paʻi ʻana i nā ʻīnika no kona opacity a me kona ikaika kala, hiki ke hana i nā mea paʻi kiʻekiʻe me nā kala ʻoniʻoni a me nā kiʻi ʻoi.

7. Plastics and Rubber: I loko o nā ʻoihana plastics a me nā ʻoihana kaʻa, hoʻohana ʻia ka titanium dioxide ma ke ʻano he mea keʻokeʻo keʻokeʻo, UV stabilizer, a me ka hoʻopihapiha hoʻopihapiha i nā huahana like ʻole e like me nā mea hoʻopihapiha, nā ʻāpana kaʻa, nā kiʻiʻoniʻoni, nā fibers, a me nā mea hao. Hoʻonui ia i nā waiwai mechanical, weatherability, a me ke kūpaʻa wela o nā huahana plastic a me nā huahana rubber.

8. Kākoʻo Catalyst: Hoʻohana ʻia ka Titanium dioxide ma ke ʻano he kākoʻo catalyst a i ʻole catalyst precursor i nā kaʻina hana kemika like ʻole, me ka catalysis heterogeneous, photocatalysis, a me ka hoʻoponopono kaiapuni. Hāʻawi ia i kahi ʻāina kiʻekiʻe, kūpaʻa wela, a me ka inertness kemika, kūpono ia no nā noi catalytic i ka synthesis organik, ka mālama ʻana i ka wai ʻino, a me ka mālama pollution.

9. Mea Uila a Uila: Hoʻohana ʻia ka Titanium dioxide i ka hana ʻana i nā seramika uila, nā mea dielectric, a me nā semiconductor ma muli o kāna mau dielectric kiʻekiʻe, nā waiwai piezoelectric, a me nā ʻano semiconductor. Hoʻohana ʻia ia i nā capacitors, varistors, sensors, solar cell, a me nā mea uila.

I ka hōʻuluʻulu ʻana, ʻo ka titanium dioxide kahi mea maʻalahi me ka nui o nā noi ma waena o nā ʻoihana e like me nā pena a me nā uhi, nā mea hoʻonaninani, nā meaʻai, nā seramika, ka pepa, nā plastics, nā uila, a me ka ʻenekinia kaiapuni. ʻO kāna hui pū ʻana o nā waiwai, me ka opacity, ka mālamalama, ka pale UV, photocatalysis, a me ka inertness kemika, he mea nui ia i nā mea kūʻai aku a me nā huahana ʻoihana.
