1. Wehewehe ʻana o ka huahana boehmite i manaʻo ʻia: ʻAʻohe ʻawahia, ʻono ʻole a ʻala ʻole kēia huahana. He colloid keʻokeʻo ka huahana pulu a he pauka keʻokeʻo ka pauka maloʻo. He like ka hoʻolaha ʻana o ka nui o nā pore, nui ka nui a maikaʻi ka omo ʻana o ka wai. Loaʻa iā ia ka maʻemaʻe radial kiʻekiʻe, hana hoʻoheheʻe maikaʻi a me nā waiwai gel thixotropic. Loaʻa i ka huahana ka maikaʻi o ka hoʻoheheʻe ʻana, maʻalahi ke hoʻoheheʻe ʻia i loko o ka waikawa ikaika a me ka hopena alkali, a he hana hoʻoheheʻe maikaʻi.
2. Ka hoʻopili ʻana a me ka mālama ʻana i ka pseudo boehmite: ua hoʻopili ʻia ka pseudo boehmite i loko o nā ʻeke ulana. E mālama i loko o kahi hale kūʻai anuanu, ea maikaʻi a maloʻo.
3. Nā hoʻohana nui o ka boehmite i manaʻo ʻia:
Hoʻohana nui ʻia kēia huahana ma ke ʻano he mea maka o ka alumina i hoʻāla ʻia e ke kākoʻo catalyst, e like me ka mea maka o ka hydrogenation catalyst, ke kākoʻo o ka hydrogenation catalyst a me ka oxychlorination catalyst.
Hiki ke hoʻohana ʻia e like me ka mea hoʻopaʻa molding no ka zeolite a me nā huahana fiber refractory silicate, e like me ka mea hoʻopaʻa no ka semi synthetic rare earth Y zeolite cracking catalyst.
He mea maka maikaʻi ka huahana no ka hana ʻana i nā paʻakai alumini like ʻole. Ma hope o ke kālai ʻia ʻana, hiki ke hoʻohana ʻia ma ke ʻano he mea desiccant, adsorbent a me ka mea lawe catalyst me nā ʻano like ʻole.
1. ʻO ka hoʻonui ʻana i ke koho ʻana o nā lako hana a me ka holoi ʻana a me ka kānana ʻana me ke kānana kāʻei hakahaka keʻena paʻa kiʻekiʻe ke kī e hōʻemi ai i ka hoʻohana ʻana i ka wai maʻemaʻe i ka hana ʻana o ka pseudo boehmite.
2. Hoʻohana ʻia ke kolu o ka wai holoi no ka hoʻohuihui ʻana o ka wai sodium aluminate e hōʻemi i ka neʻe ʻana o waho a hoʻomaikaʻi i ka pono o ka hoʻohana ʻana i ka wai hou. He mea nui ia e hōʻemi i ka hoʻohana ʻana i ka wai hou.
3. ʻO ke ala nui e hōʻemi ai i ka hoʻohana ʻana i ka wai hou, ʻo ia ka hoʻonui pono ʻana i ka mahana o ka wai wela holoi, e hana i kahi ʻōnaehana hana kūpono a hoʻohana i kahi ʻōnaehana hoʻoluʻu ʻāpana.
ʻO ka pseudo boehmite kahi ʻano pseudo boehmite me ka crystallization colloidal piha ʻole. Nā Huahana 1, ʻaʻohe ʻawahia, 2, ʻono ʻole, 3, ʻala ʻole, 4, pae crystalline kiʻekiʻe maʻemaʻe, 5, solubility maikaʻi, 6, hoʻopili ikaika, 7, me nā ʻano gel thixotropic. Hiki ke hoʻohana nui ʻia ka pseudo boehmite i ka petrochemical, chemical fertilizer, nā huahana silicate, ka palekana o ke kaiapuni a me nā ʻoihana ʻē aʻe.
