Noi ʻana o ka Aluminium Hydroxide

ʻO "alumina kemika" e pili ana i ka hana ʻana o ka ingot alumini koe wale nō ka alumina, ka alumini oxide a me nā huahana alumini hydroxide i hoʻokaʻawale ʻia a i ʻole nā ​​​​huahana hoʻonui. He mau haneli o nā ʻano alumina kemika, a he ākea nā noi ma nā ʻano like ʻole. E hoʻolauna kēia ʻatikala i nā noi pili o ka alumini hydroxide.

ʻO ka aluminium hydroxide, i ʻike ʻia hoʻi ʻo hydrated alumina, hydrous alumina, alumina hydrate, he hui amphoteric maʻamau, hiki ke hoʻoheheʻe ʻia i loko o nā waikawa a me nā kumu, hiki ʻole ke hoʻoheheʻe ʻia i ka wai a me ka waiʻona. ʻO ke ʻano maʻamau ʻo Al2O3 • H2O me kahi kiko heheʻe o 300 (nalowale o ka wai). Wahi a kona ʻano wai, hiki ke hoʻokaʻawale ʻia ka moʻo aluminium hydroxide i: alumina trihydrate, alumina monohydrate, low crystallinity alumina a me amorphous alumina hydroxide. Hoʻokaʻawale ʻia mai ka bauxite, hiki ke hana ʻia mai ka paʻakai alumini a me ka sodium hydroxide me ka wai ammonia. ʻElua ʻano crystalline a me amorphous (gel).

ʻO ka alumini hydroxide amorphous he alkali haʻahaʻa, hao haʻahaʻa, nā ʻāpana maikaʻi, a keʻokeʻo kiʻekiʻe. Loaʻa i ke kumu hoʻohālike pono nā pono o ka paʻakikī nui, ke kūpaʻa wela, ke kūpaʻa ʻaʻahu, kūpaʻa kemika maikaʻi, ʻaʻohe ʻawaʻawa, ʻaʻohe ʻono, ʻaʻohe volatile, dehydration a me ka omo wela i ka wā e hoʻomehana ʻia ai ke kumu hoʻohālike pono ma mua o 250 DEG C, a he maikaʻi ka hoʻopau ʻana i ka uahi a me ka pale ʻana i ka lapalapa. ʻO nā wahi noi nui penei.

ʻO ka aluminiuma hydroxide kahi ʻano mea hoʻopihapiha inorganic i hoʻomaʻemaʻe ʻia, haʻahaʻa kona ʻano haumia, a ʻo nā polymers e hoʻohana ana i ka aluminia hydroxide ma ke ʻano he mea hoʻopiha he polyurethane resin, epoxy resin, polyethylene, polypropylene, styrene butadiene rubber, etc. Ua hoʻohana ʻia ka aluminiuma hydroxide ma ke ʻano he mea pale lapalapa a me ka mea hoʻopau uahi i loko o ka resin unsaturated no nā makahiki he nui.

ʻO ke ʻano hana lapalapa no ka hoʻohui ʻana i ka ATH i ka polymer, e hōʻemi ana i ka nui o ka wahie; ua hoʻomaka ka alumini hydroxide ma 250 DEG C endothermic dehydration, ka pale ʻana i ka piʻi ʻana o ka mahana polymer; ka hoʻoheheʻe ʻana o ka mahu wai i ka nui o ka oxygen, ka lohi o ka puhi ʻana; i ka hoʻoulu ʻana i ka ʻili lapalapa o ka alumina hiki ke pale i ka hoʻomau ʻana o ka hopena puhi.

Hoʻohana nui ʻia ka aluminiuma hydroxide i ka ʻoihana uhi no nā uhi ʻili, nā mea hoʻopihapiha, a me ka pepa ʻaʻole e hiki ke puhi. Hiki i ka aluminiuma hydroxide ke hoʻomaikaʻi i ka ʻōlinolino, ka hoʻomālamalama ʻana, ke kūʻē ʻana i ka mālamalama, ka laumania a me ka hiki ke paʻi ʻia o ka pepa. Hiki ke hoʻohana ʻia ka aluminiuma hydroxide ma ke ʻano he mea maka no ka pepa i uhi ʻia, a e pani ʻo titania no ka lepo. ʻO ka nui o ka ʻāpana aluminia hydroxide i hoʻohana pinepine ʻia he 0.7-1.4 mu m.

Pepa pale ahi: pale lapalapa, hoʻoheheʻe ʻia ke ahi, akā ʻaʻole e ʻā. Hana ʻia me ka pepa asbestos, a i ʻole ka pepa pale lapalapa me ka pepa kūpono (e like me ka alumini hydroxide) a me ka mālama ʻana.

ʻAʻohe ʻawahia a ʻono ʻole ka aluminiuma hydroxide, hoʻoheheʻe ʻole ʻia i ka wai, he ʻano maikaʻi ia o ka mea hoʻopili kūʻokoʻa, ʻo ka paʻakikī o ka toothpaste agent Mohs o ka hana ʻoihana o ka aluminia hydroxide he 2.5-3.5, ʻoi aku ka maʻemaʻe ma mua o 99%, waiwai pH 8.0-9.5, waiwai D50 he 8-15 microns, kūpono ke kumukūʻai, he mea hoʻopili maikaʻi ia no ka toothpaste, kūpono ka fluoride a me ka hana, hana maikaʻi loa. ʻO ia kekahi o nā mea hoʻopili toothpaste lāʻau lapaʻau kūpono.

ʻO Mullite (a i ʻole mullite) kahi moʻo o nā minelala i haku ʻia me ka aluminosilicate. ʻO Mullite wale nō ka hui ʻelua mau mea paʻa i loko o ka ʻōnaehana Al2O3 SiO2. He kakaikahi kēia ʻano minelala. He ʻano refractory kiʻekiʻe ia, a hiki ke hana ʻia ka mullite ma ka hoʻomehana ʻana i ka alumini silicate ma ke ʻano hana. Hoʻohana nui ʻia ʻo Mullite i nā refractories, ceramics, metallurgy, casting, electronics a me nā ʻoihana ʻē aʻe. Loaʻa iā ia nā ʻano o ke kūpaʻa wela kiʻekiʻe, ka ikaika kiʻekiʻe a me ka conductivity thermal liʻiliʻi.

Eia kekahi, hiki ke hoʻohana ʻia ka alumini hydroxide e like me ke kinikini hana, ka agate hana, ka mea hoʻopiha kāpeti; ka hana ʻana o ka alumini sulfate, alum, alumina, hydrated alumina, sodium aluminate chemical materials rubber; flame retardant; hoʻohana ʻia e like me ka mea hoʻopiha a me nā mea hoʻohui o nā mea hoʻopili a me nā mea hoʻopaʻa; sieve molekala synthetic; no nā gastricantiacids etc.

ʻO ke ʻano gel alumini hydroxide he Aluminium Hydroxide Gel, boehmite, a me amorphous alumina. Loaʻa iā ia ka hoʻopili maikaʻi, ka hoʻoheheʻe ʻana, ke kūpaʻa wela kiʻekiʻe, ka nui o ka wela, ka conductivity thermal haʻahaʻa, ke kūpaʻa maikaʻi i ka corrosion a me ke kūpaʻa oxidation, ka ikaika kiʻekiʻe a me ka ʻili laumania.

ʻO ka aluminiuma hydroxide kekahi o nā mea nui o ka gel alumini ʻōpū no ka mālama ʻana i ka waikawa ʻōpū a me ka ʻōpū, nā lāʻau lapaʻau kuʻuna, nā hoʻomākaukau hui e like me ka huaora U a me nā capsules alumini, nā papa Aluminiuma Hydroxide a me nā mea nui ʻē aʻe, hiki ke hoʻohana ʻia no nā mea lāʻau lapaʻau. ʻO ke ʻano o kāna waikawa anti gastric ʻo Al (OH)3+6HCl=2AlCl3+3H2O. ʻEono wai alumina i hoʻomākaukau ʻia mai ka aluminiuma hydroxide hiki ke hoʻohana ʻia ma ke ʻano he mea gelling i ke kahua o ka lāʻau lapaʻau a me nā mea hoʻonani.

ʻO ka mālama ʻana i ka ʻili a me ka hoʻopili ʻana i ka Aluminium Hydroxide Gel hiki ke hana ʻia me ka fiber inorganic a organic paha, me ka hoʻohana ʻana i kona kūpaʻa wela kiʻekiʻe a me ka hoʻopau ʻana i ka ʻili, hoʻohana nui ʻia i ka hana ʻana i nā mea hana seramika kiʻekiʻe, hoʻohana ʻia hoʻi no ka hana ʻana i ka porcelain uila; i ka manawa like he mea hoʻopihapiha inorganic nō hoʻi ia.
