ʻAlumini Hydroxide Maikaʻi

Hoʻohana: i ka hana ʻana o ka alumini hydroxide. ʻAno: ua kuʻi ʻia ka hua alumini hydroxide, e kāwili me ka hopena aluminate. Hoʻomoʻa ʻia ka hopena o ka hoʻokuʻu ʻana me ka hoʻoulu ʻana a mālama ʻia me ke kalapona ʻokikene. Ke hoʻokaʻawale nei i ka alumini hydroxide mai ka waiʻona makuahine. Holoi ʻia ka alumini hydroxide.

Pili ka mea i hana ʻia i ka hana ʻana o ka alumini hydroxide.

ʻO ke ʻano hana no ka loaʻa ʻana o ka alumini hydroxide maikaʻi [1] kahi e hana ʻia ai ke kaʻina hana i ʻelua mau pae. I ke kahua mua, ua hoʻopau ʻia ka hopena aluminate me ka waikawa hydrochloric, a ʻo ka hopena o ka alumini hydroxide i hoʻopuehu maikaʻi ʻia e hoʻohana ʻia ma ke ʻano he decomposition hua o ka hopena aluminate supersaturated i ke kahua ʻelua.

ʻO ka hemahema o kēia ʻano hana, ʻo ia nā kumukūʻai kiʻekiʻe i hoʻokumu ʻia e ka neutralization o ka alkali caustic e ka waikawa, ka hōʻiliʻili ʻana o nā mea haumia i loko o nā hopena, a pēlā aku.

ʻO ka mea kokoke loa i kēia mea i hana ʻia he ʻano hana [2] kahi e hoʻohana ai i ka pauka alumini hydroxide ma ke ʻano he hua.

ʻO ka hemahema o kēia ʻano hana, ʻo ia ka hoʻonā wintopo kiʻekiʻe.

ʻO ka pahuhopu o ka mea i hana ʻia, ʻo ia ka hoʻemi ʻana i ke kumukūʻai ikehu o ka ʻāpana ma o ka hoʻonui ʻana i ka hana o ka alumini hydroxide maikaʻi.

Ke hana ʻana i nā hopena aluminate me ke kalapona ʻokikene, hoʻohana nui ʻia ke kaʻina hana carbonization i nā hale hana alumina e hana ana ma ke ʻano o ka sintering. Hiki i ka hoʻohana ʻana i ka carbonization ke hāʻawi i kahi hydroxide puka kiʻekiʻe.

ʻO ka nui o ka palaoa o ka alumini hydroxide i loaʻa i ke kaʻina hana carbonization e hilinaʻi nui ʻia i ka mahana o ka carbonization a me ka haku mele ʻana o nā hopena aluminate (ka nui o ka alkali a me ka alumina).

ʻO ke ʻano hana i ʻike ʻia (Nā metala māmā. 1937, No. 10, S. 8-15) ka hana ʻana o ka hydroxide alumini maikaʻi ma o ke ʻano o ka carbonization, me ka hana ʻana o nā hopena aluminate ultracracker carbon dioxide (concentration 200 g/l) ma nā mahana haʻahaʻa (30^{e pili ana}C).

ʻOiai ke hāʻawi nei kēia ʻano hana i kahi aluminum hydroxide maikaʻi loa, ʻaneʻane hiki ʻole ke hoʻohana ʻia ma muli o nā pilikia loea e kū mai ana i nā pae hope o ke kaʻina hana: ʻo ke Keʻena o ka ua a me ka holoi ʻana.

Eia nō naʻe, i ka wā e hoʻohana ai i ke ʻano nizkokontsentrirovannye o ke kalapona ʻana, ua hāʻule.

ʻO ka nui o ka palaoa o ka alumini hydroxide i loaʻa ma lalo o kēia mau kūlana, i hōʻailona ʻia e ka haku mele like ʻole a me ka nui o nā ʻāpana coarse.

ʻO ka mea i hana ʻia, ʻo ia ke ʻano o ka hana ʻana o ka alumini hydroxide maikaʻi, me ka wili ʻana i ka hua alumini hydroxide, ke kāwili ʻana me ka hopena aluminate, ka hoʻomoʻa ʻana i ka hopena o ka hoʻokuʻu ʻana me ka hoʻoulu ʻana, ka hoʻokaʻawale ʻana i ka alumini hydroxide mai ka wai makuahine a me ka holoi ʻana, ma mua o ka hoʻokaʻawale ʻana i ka alumini hydroxide mai ka slurry wai makuahine, ua mālama ʻia me ke kalapona ʻokikene.

Ua hōʻike ʻia nā haʻawina i ka wā e hana ai i nā hopena aluminate kalapona dioxide e loaʻa ana ka nui o nā mea paʻa, ua aneane like ka nui o ka ʻāpana.

I ka hana ʻana i ka hua i kuʻi ʻia i loko o ka hopena aluminate supersaturated, a me ka hoʻomāhuahua ʻana i ka hopena o ka hoʻokuʻu ʻana me ka hoʻoulu ʻana e hua mai i ka nui o ka alumini hydroxide i hoʻopuehu nui ʻia. Eia nō naʻe, ʻo ka hua o ka alumini hydroxide maikaʻi me ka ʻole o ka hana hou ʻana o ka hoʻokuʻu ʻana he haʻahaʻa a hilinaʻi ia i ka nui o ka alkali caustic i loko o ka hopena: ʻo ke kiʻekiʻe o ka nui o ka alkali, ʻo ka haʻahaʻa o ka hopena.

I ka wā e hana ai i ke kalapona ʻokikene, ʻo ka hoʻokuʻu mua ʻana e hāʻawi ʻia e ka puka o ka alumini hydroxide e like me ka hana ʻana o ka hoʻokuʻu ma hope o ka hōʻike mua ʻana, akā naʻe, hoʻonui nui ka nui o nā ʻāpana o ka alumini hydroxide.

Hiki ke hoʻokō ʻia ke ʻano me ka hoʻohana ʻana i nā lako i loaʻa.

ʻO ke ʻano hana e makemake nui ʻia nā mea kanu alumina ma muli o ka ʻenehana spechitelnoj.

ʻO ka hoʻohālikelike ʻana i ka ʻikepili mai nā hoʻokolohua he nui e hōʻike ana i ka hana ʻana o ka slurry hydrate i loaʻa ma hope o ka hōʻike ʻana i ka hui ʻana o ka hopena aluminate a me nā hua i ʻoki ʻia, ʻo ke kalapona dioxide e ʻae iā ia e loaʻa ka alumini hydroxide maikaʻi a hōʻoia i ka hua huahana kiʻekiʻe.

ʻO PRI me R 1. Ua hui pū ʻia ʻo 0.02 kg o ka alumini hydroxide me ka awelika o 2.8 μm me 1 lita o ka hopena aluminate e loaʻa ana, g/l: Na₂CMOS 100,8; Al₂O₃107,4.

Ua hoʻoholo ʻia ka hoʻokuʻu hopena ma 60^{e pili ana}Me nā hola he 10 ma waho, ʻo ka nui o ka alumini hydroxide maikaʻi he 40,4, ʻo ka awelika o ka nui o nā ʻāpana i loko o ka sediment he 3.6 μm. ʻO ka haku mele ʻana o ka pae wai o ka hoʻokuʻu ʻana, ka hui ʻana o Noi, aia ma kahi o 12. CO₂ʻO ka manawa hana o 6 mau hola i kahi ʻike koena o ka sodium oxide i loko o ka hopena ma hope o ka mālama ʻana o 5.6 g/L.

ʻO ka awelika o ka nui o nā ʻāpana i loko o ka sediment ma hope o ka mālama ʻana he 4.8 μm. ʻO ka hopena o ka alumini hydroxide he 102,5.

PRI mme R 2. Ua hui pū ʻia ʻo 0.02 kg o ka alumini hydroxide me ka awelika o 2.8 μm me 1 lita o ka hopena aluminate a ua mālama koke ʻia (me ka ʻole o ka hōʻike ʻana) me ke kalapona ʻokikene. ʻO ka lōʻihi o ka mālama ʻana a me ka nui o CO₂i loko o kahi hui kinoea e like me ka laʻana 1.

ʻO ka hopena o ka alumini hydroxide he 103,1, ʻo ka awelika o ka nui o nā ʻāpana i loko o ka sediment he 30.4 μm.

No laila, ʻo ka hoʻokō ʻana o ke kaʻina hana i luna nei: ʻo ka hui ʻana o ka hopena aluminate me ka extract hua i kuʻi ʻia, ʻo ka hopena o ka hoʻokuʻu ʻana, ka slurry carbonation ma mua o ka hoʻokaʻawale ʻana o ka alumini hydroxide hiki ke hāʻawi i kahi alumini hydroxide maikaʻi kiʻekiʻe.

KE ʻANO o ka hana ʻana o ka ALUMINUM HYDROXIDE MAIKAʻI, me ka wili ʻana i ka hua aluminum hydroxide, ke kāwili ʻana me ka hopena aluminate, ka hoʻomānoanoa ʻana i ka hopena o ka hoʻokuʻu ʻana me ka hoʻoulu ʻana, ka hoʻokaʻawale ʻana i ka aluminum hydroxide mai ka wai makuahine a me ka holoi ʻana,
