Titanium Dioxide
ʻO ka Titanium dioxide kahi puaʻa inorganic keʻokeʻo, ʻo ka mea nui ʻo TiO2.
Ma muli o kāna mau waiwai paʻa kino a me ke kemika, maikaʻi o ka optical a me ka hana puaʻa, ua manaʻo ʻia ʻo ia ka puaʻa keʻokeʻo maikaʻi loa ma ka honua. Hoʻohana nui ʻia ia i nā kula he nui e like me ka uhi ʻana, ka hana pepa, nā mea hoʻonaninani, nā mea uila, nā ceramics, nā lāʻau lapaʻau a me nā mea hoʻohui meaʻai. ʻO ka hoʻohana ʻana o ka titanium dioxide i kēlā me kēia kumulāʻau i manaʻo ʻia he hōʻailona koʻikoʻi e ana i ke kiʻekiʻe o ka hoʻokele waiwai o kahi ʻāina.
I kēia manawa, ua hoʻokaʻawale ʻia ke kaʻina hana o ka titanium dioxide ma Kina i ke ʻano sulfuric acid, chloride method a me hydrochloric acid method.
Nā uhi
Ua kūpaʻa ʻo Sun Bang i ka hāʻawi ʻana i ka titanium dioxide kiʻekiʻe no ka ʻoihana uhi. ʻO ka Titanium dioxide kekahi o nā mea pono i ka hana ʻana i nā uhi. Ma kahi o ka uhi ʻana a me ka hoʻonaninani, ʻo ka hana o ka titanium dioxide ka hoʻomaikaʻi ʻana i nā waiwai kino a me nā kemika o nā coatings, hoʻomaikaʻi i ka paʻa kemika, hoʻomaikaʻi i ka ikaika mechanical, adhesion a me ka corrosion resistance o ka noi. Hiki i ka Titanium dioxide ke hoʻomaikaʻi i ka pale UV a me ke komo ʻana o ka wai, a pale i nā māwae, hoʻopaneʻe i ka ʻelemakule, hoʻolōʻihi i ke ola o ka kiʻi pena, ka mālamalama a me ka pale ʻana i ka wā; i ka manawa like, hiki i ka titanium dioxide ke mālama i nā mea waiwai a hoʻonui i nā ʻano like.
Palaki & Rubber
ʻO ka plastik ka lua o ka mākeke nui loa no ka titanium dioxide ma hope o ka uhi ʻana.
ʻO ka hoʻohana ʻana i ka titanium dioxide i nā huahana plastik e hoʻohana i kona mana huna kiʻekiʻe, mana decolorizing kiʻekiʻe a me nā waiwai puaʻa ʻē aʻe. Hiki i ka Titanium dioxide ke hoʻomaikaʻi i ka pale wela, ka pale māmā a me ka pale ʻana i ka wā o nā huahana plastik, a me ka pale ʻana i nā huahana plastik mai ke kukui ultraviolet e hoʻomaikaʻi ai i nā waiwai mechanical a me nā uila o nā huahana plastik. He mea nui ka dispersibility o ka titanium dioxide i ka mana kala o ka plastic.
Inika & Pai
No ka mea ʻoi aku ka lahilahi o ka ʻīnika ma mua o ka pena, ʻoi aku ka nui o nā koi no ka titanium dioxide ma mua o ka pena. ʻO kā mākou titanium dioxide ka liʻiliʻi liʻiliʻi, ka hāʻawi like ʻana a me ka hoʻopuehu kiʻekiʻe, i hiki ai i ka ʻīnika ke hoʻokō i ka mana huna kiʻekiʻe, ka mana kiʻekiʻe a me ka nani.
Ka hana pepa
I ka ʻoihana hou, nā huahana pepa e like me ke ʻano o ka hana ʻana, ʻoi aku ma mua o ka hapalua o ia mau mea i hoʻohana ʻia no nā mea paʻi. Pono ka hana ʻana o ka pepa e hāʻawi i ka opacity a me ka ʻōlinolino kiʻekiʻe, a he mana ikaika e hoʻopuehu i ka mālamalama. ʻO ka Titanium dioxide ka puaʻa maikaʻi loa no ka hoʻoponopono ʻana i ka opacity i ka hana pepa ma muli o kāna ʻōlelo kuhikuhi refractive maikaʻi loa a me kāna kuhikuhi hoʻopuʻi māmā. ʻO ka pepa e hoʻohana ana i ka titanium dioxide he keʻokeʻo maikaʻi, ikaika kiʻekiʻe, ʻālohilohi, lahilahi a maʻalahi, ʻaʻole e komo i ka wā i paʻi ʻia. Ma lalo o nā kūlana like, ʻo ka opacity he 10 mau manawa kiʻekiʻe ma mua o ka calcium carbonate a me ka talcum pauka, a hiki ke hoʻemi ʻia ka maikaʻi e 15-30%.
