ʻAlumini hydroxideHe keʻokeʻo maikaʻi, he helu kuhikuhi refractive waena, maʻalahi ke kaʻina hana, me ka pale ahi maikaʻi, ka hoʻopau ʻana i ka uahi a me nā ʻano ʻē aʻe, no laila he mea hoʻopihapiha maikaʻi loa ka alumini hydroxide e like me ka pōhaku hana.
ʻO nā huahana pōhaku artificial i hana ʻia me nā mea maka alumini hydroxide he mau ʻano penei:
Māmā ke kaumaha, haʻahaʻa ke kumukūʻai, maʻalahi ka hana ʻana, waihoʻoluʻu maikaʻi, paʻakikī maikaʻi, hiki ke hoʻokō i ka humuhumu maʻalahi, a he maʻalahi kāna ʻano hana, pōkole ka pōʻaiapuni hana. No laila, laha koke ia i nā wahi āpau o ka honua a ua kapa ʻia ʻo ia he mea kūkulu hale i hoʻohana nui ʻia.
I kēia manawa, ʻo ke koi makahiki o ka pōhaku artificial o ka honua me ka alumini hydroxide ma kahi o 700,000 tons, a i kēlā me kēia makahiki me kahi o 10 pakeneka o ka piʻi ʻana o ka nui. ʻOi aku ka piha ʻole o nā helu helu, ʻo ke koi makahiki o ka mākeke pōhaku artificial o Kina he 1100 mika kuea ma luna, a ʻo ka mana hana o nā mea hana pōhaku artificial kūloko o kēia manawa he 7 miliona mika kuea wale nō, he nui ka mākeke.
Ma muli o ke kaʻina hana sintering kūikawā a me ke kaʻina hana desilication hohonu o ka hopena sodium chlorate, ʻo nā huahana alumina i hana ʻia e ke kaʻina hana sintering alkali lime he mau ʻano o ke keʻokeʻo kiʻekiʻe a me ka haʻahaʻa o ka hao. Ma muli o ka hoʻomohala wikiwiki ʻana o ka ʻoihana pōhaku hana, ke hoʻonui koke ʻia nei ka laina hana hana alumini hydroxide filler i ka māhele mākeke ma ka home a ma waho.
Eia nā mea hana hana alumini hydroxide ma ka pōhaku hana me ka alumini hydroxide ʻekolu mau hana hana e like me kēia:
(1) ʻO nā huahana i hana ʻia e ke ʻano hoʻokaʻawale kalapona he keʻokeʻo iki aʻe, ʻoi aku ka nui o ka pH a me SiO2% o nā huahana, a haʻahaʻa ka maʻemaʻe. I ka hana ʻana o nā huahana hoʻokaʻawale kalapona, he liʻiliʻi ka nui o ka palaoa mua o ka huahana, he ʻino loa ka ʻili o ka palaoa, he palupalu ke kristal kristal, ʻilihune ke kekelē crystallization, nui nā pores, ʻo ia ke kumu o ka nui o ka omo ʻaila o ka huahana, me kāna hana ʻana i ka papa pōhaku artificial keʻokeʻo.
(2) ʻoi aku ka haʻahaʻa o ke keʻokeʻo o nā huahana i hana ʻia e ke ʻano hoʻokaʻawale ʻano, haʻahaʻa ka nui o ka omo ʻana o ka aila, haʻahaʻa ka waiwai pH a me ka SiO2% o nā huahana, a kiʻekiʻe ka maʻemaʻe o nā huahana. I ka hana ʻana o nā huahana, ʻoi aku ka piha o ka ulu ʻana o ke kristal, maʻemaʻe ka ʻili o ka palaoa kristal, ʻoi aku ka mānoanoa o nā kristal kristal, maikaʻi ke kiʻekiʻe o ka crystallization, liʻiliʻi ka hakahaka ma waena o nā ʻāpana, ʻo ia ka huahana omo ʻaila haʻahaʻa e makemake ai ʻoe, me kāna hana ʻana i ka papa pōhaku artificial ikaika kiʻekiʻe.
(3) ʻO nā huahana i hana ʻia e ke ʻano hui ʻana he haʻahaʻa loa ka helu omo ʻaila me ka lalo keʻokeʻo. ʻO ke ʻano hui ʻana o nā huahana, ʻo nā ʻāpana nui o nā mea maka, a me nā ʻāpana liʻiliʻi o ka mea hoʻopihapiha kalapona, gradation, hoʻopiha piha, e hoʻemi nui i ka helu omo ʻaila o ka huahana alumini hydroxide, i ka manawa like, haʻahaʻa ka viscosity o ka huahana, ʻoi aku ka liʻiliʻi ma mua o 20000 eps, me kona kumukūʻai haʻahaʻa, ʻaʻole pono nā mea kūʻai aku e hoʻokaʻawale i ka mea hoʻopihapiha alumini hydroxide, e mālama i ka hana.
