ʻIke ʻia ka ʻoihana alumini hydroxide ʻo alumina hydrate, ma muli o kona keʻokeʻo maikaʻi, ka ratio refractive maʻalahi, maʻalahi e hana, me ka pale lapalapa maikaʻi a me ka hana hoʻopau uahi, no laila he mea hoʻopiha pōhaku artificial maikaʻi loa ka alumini hydroxide.
ʻO nā huahana pōhaku hana i hana ʻia mai ka alumini hydroxide he mau ʻano kēia:
Māmā ke kaumaha, haʻahaʻa ke kumukūʻai, maʻalahi ke hana, waihoʻoluʻu maikaʻi, paʻakikī maikaʻi, hiki ke hoʻokō ʻia ka splicing seamless, a he maʻalahi kāna ʻano hana, pōkole ka pōʻaiapuni hana. No laila, ua laha koke ia i nā wahi āpau o ka honua, i ʻike ʻia he ʻano mea kūkulu hale i hoʻohana nui ʻia.
I kēia manawa, ʻo ka noi makahiki o ka honua no ka alumini hydroxide no ka pōhaku hana ma kahi o 700,000 tons, a ʻo ka nui o ka ulu makahiki ma kahi o 10%. ʻOi aku ka nui o nā helu helu piha ʻole, ʻo ka noi makahiki o Kina no ka mākeke pōhaku hana ma 1100 mika kuea, a ʻo ka mana hana kūloko o kēia manawa o nā mea hana pōhaku hana he 7 miliona mika kuea wale nō, nui ka hiki ke mākeke.
Ma muli o ke kaʻina hana sintering kūikawā a me ke kaʻina hana desilication hohonu o ka hopena sodium chlorate i ka hana ʻana o ka alumina ma o ke kaʻina hana sintering lime caustic, ʻo nā huahana alumini hydroxide i hana ʻia he mau ʻano o ke keʻokeʻo kiʻekiʻe a me ka haʻahaʻa o ka hao, a he mau pono kūikawā. Ma muli o ka hoʻomohala wikiwiki ʻana o ka ʻoihana pōhaku artificial, ke hoʻonui koke ʻia nei ka laina hana o ka mea hoʻopihapiha alumini hydroxide e hoʻonui i ka māhele mākeke ma ka home a ma waho.
Eia ka mea hana o ka alumini hydroxide no ka pōhaku hana me ka hana ʻana o ka alumini hydroxide ʻekolu mau kaʻina hana i hoʻolauna ʻia penei:
(1) ʻO nā huahana i hana ʻia e ka hoʻokaʻawale kalapona he keʻokeʻo iki aʻe, ʻoi aku ka waiwai pH kiʻekiʻe a me ka SiO2% kiʻekiʻe, a haʻahaʻa ka maʻemaʻe. ʻO ke ʻano hana kalapona o ka huahana, he liʻiliʻi ka nui o ka palaoa mua o ka huahana, he ʻino loa ka ʻili o ka palaoa, ʻoi aku ka wehe ʻana o ke kristal kristal, ʻilihune ke kiʻekiʻe o ka crystallization, ʻoi aku ka nui o ka porosity, ʻoi aku ka kiʻekiʻe o ka helu omo aila huahana, me kāna hana ʻana i ka papa pōhaku artificial he kiʻekiʻe keʻokeʻo.
(2) ʻO nā huahana i hana ʻia e ke ʻano hoʻokaʻawale he haʻahaʻa keʻokeʻo, haʻahaʻa ka nui o ka omo ʻana o ka aila, haʻahaʻa ka waiwai pH, haʻahaʻa ka SiO2% o nā huahana a ʻoi aku ka maʻemaʻe. ʻOi aku ka maikaʻi o ka hoʻomohala ʻana o ke aniani kristal ma ke ʻano mahele hua, ʻoi aku ka maikaʻi o ka hoʻomohala ʻana o ke aniani, ʻoi aku ka ʻōlinolino a me ka maʻemaʻe o ka ʻili o nā ʻāpana kristal, ʻoi aku ka mānoanoa o ke aniani kristal, ʻoi aku ka maikaʻi o ke kekelē kristal, liʻiliʻi ka hakahaka ma waena o nā ʻāpana, ʻo ia ka haʻahaʻa o ka nui o ka omo ʻana o ka aila o ka huahana e makemake ai ʻoe, me kāna hana ʻana i ka ikaika o ka papa pōhaku artificial.
(3) ʻO nā huahana i hana ʻia e ke ʻano hui ʻana he haʻahaʻa loa ka omo ʻana o ka aila a me ka haʻahaʻa loa ke 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 nui o ka omo ʻana o ka aila 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.
