ʻO kāu mea hoʻolako Boehmite alakaʻi
Aia ʻo Luoyang Zhongchao New Material Co., Ltd. (ma hope aku i kapa ʻia ʻo "ZC-TECH") ma Industrial Cluster Zone, Henan Province, Kina, e uhi ana i kahi ʻāpana ʻoi aku ma mua o 60 mau ʻeka. Hoʻokumu ʻia i ka makahiki 2003, he ʻoihana ia e hoʻohui i ka noiʻi ʻoihana a me ka hoʻomohala ʻana, ka hana ʻana, a me ke kūʻai ʻana i nā mea hou e pili ana i ke kaiapuni a me ka pollution -free. ʻO kāna mau huahana nui he aluminika ma muli o ka lapalapa maikaʻi loa -mea hoʻopaʻa ahi a me ka magnesium ma muli o ke ahi maikaʻi loa-mea hoʻopaʻa ʻia, alumina kūikawā, alumina pōʻai, boehmite, nā seramika kiʻekiʻe, nā seramika uila a me nā mea ʻokoʻa ʻē aʻe.
Hāʻawi i nā hoʻolālā hoʻohalahala maʻamau no nā koi kūikawā e like me ka hoʻopiha piha ʻana, ka uahi haʻahaʻa, a me nā noi manuahi -halogen.
Na Waiwai Boehmite
Nā waiwai kemika
Keʻokeʻo; ortho{0}}rhomb; a=0.286 nm, b=1.2227nm, c=0.380nm; ʻo ka paʻakikī he 3.5–4 Mohs; Loaʻa i ka hopena hydrothermal o nā slurries hydroxide ma 200 degere –250 degere.
ʻO ka Boehmite he alumini oxide hydroxide (-AlO(OH)) mineral, he ʻāpana o ka alumini oka bauxite. Aia ia i ka ʻōnaehana orthorhombic a he ʻano papale. I loko o kēlā me kēia papa hana hoʻokahi, ua hoʻonohonoho ʻia nā ion oxygen ma kahi kokoke-kubiko i hoʻopaʻa ʻia ma nā piko o ka octahedron, a aia nā iona alumini i waenakonu o ka octahedron e hana i kahi papalua-papa. , Aia nā radical hydroxide ma luna o ka ʻili o ka hale i hoʻopaʻa ʻia, a ua hoʻopili ʻia nā papa e nā paʻa hydrogen.
Nā waiwai kino
The most important aluminous minerals in bauxite are gibbsite (Al(OH)3), boehmite (AlO(OH)) and diaspore (AlO(OH)), however gibbsite requires lower digestion temperature to be dissolved (typically ~145oC) as compared to boehmite and diaspore (typically >240 oC), ka hoohalike (1 – 2). No laila, hoʻolālā ʻia nā mea hoʻoheheʻe alumina e hoʻomaʻamaʻa kūikawā i kahi ʻano bauxite. ʻOiai e hana mau ʻia nā bauxite boehmitic me ka hoʻohana ʻana i nā kūlana hoʻoheheʻe 'kiʻekiʻe' (no ka hoʻihoʻi ʻana i ka boehmite) ma ke kumumanaʻo, hiki ke hana ʻia ka bauxite boehmitic i loko o kahi mea kanu haʻahaʻa me ka liʻiliʻi ʻole o ke kaʻina hana inā haʻahaʻa nā pae boehmite, ʻoiai ʻaʻole i hoʻoheheʻe ʻia kēia ʻano boehmite, e hoʻonui ana i ke koena i ka hoʻomaʻamaʻa.

Usea o Boehmite
ʻO ka hana alumini
ʻO Boehmite kahi mea mua i ke kaʻina hana Bayer, kahi i calcined ai e hana i ka alumina. A laila hoʻoheʻe ʻia kēia alumina e unuhi i ka metala alumini. Hoʻopili pololei ka maʻemaʻe o ka boehmite i ka maikaʻi a me ka maikaʻi o ka hana alumini, e lilo ia i mea koʻikoʻi.
Catalysts & petrochemicals
Ma nā noi catalytic, lawelawe ʻo boehmite i mea kākoʻo. ʻO kona ʻāpana ili kiʻekiʻe a me ka paʻa wela e hoʻonui i ka hana catalyst, ʻoi aku hoʻi i nā kaʻina hana hoʻomaʻemaʻe a me ka petrochemical. Loaʻa kēia i nā hopena kemika ʻoi aku ka maikaʻi a hoʻemi i nā kumukūʻai hana.
ʻO nā keramika & refractory
Hoʻohana ʻia nā pauka boehmite kūpaʻa kiʻekiʻe i ka hana ʻana i nā pōhaku lepo a me nā ʻāpana keramika. Kūleʻa kēia mau mea i ka wela nui i loko o nā kapuahi, kilns, a me nā reactors, e hōʻoia ana i ka lōʻihi a me ka palekana.
Polymers & composites
Hoʻokomo ʻia ʻo Boehmite i loko o nā matrices polymer e hoʻomaikaʻi i ka paʻa wela a me ka ikaika mechanical. Hoʻohana kēia noi i nā ʻoihana e like me ka aerospace a me ka hana kaʻa, kahi e pono ai nā mea māmā a paʻa.
Electronic & insulation
Ma muli o kāna mau waiwai insulating, hoʻohana ʻia ka boehmite i nā mea uila a me kahi mea dielectric. ʻO kona kūpaʻa ma lalo o ke koʻikoʻi uila e hōʻoia i ka hana lōʻihi-ma nā mea hana.
Kaʻahele:ʻAʻole -mea pōʻino, akā i ka wā o ka lawe ʻana i mea e pale ai i ka makū, e maloʻo a hoʻopaʻa ʻia.
Waihona:E mālama ma kahi maloʻo a me ka makani, ʻaʻole ma ka o
