Noi

· Inoa huahana: pauka ʻokikene alumini

·Ka maʻemaʻe o ka huahana: 99.9%, 99.99%

·Nā hiʻohiʻona huahana: kiʻekiʻe ke kiko heheʻe, paʻakikī kiʻekiʻe, insulation a me ke kūpaʻa wela

· Ka laulā noi: hiki ke hoʻohana ʻia ka alumini oxide ma ke ʻano he reagent analytical, dehydration o ka mea hoʻoheheʻe organik, adsorbent, mea hoʻoulu hopena organik, abrasive, mea hoʻopili polishing, mea maka no ka hoʻoheheʻe ʻana o ka alumini, refractory, etc.

ʻO ke kumukūʻai alumini oxide he ʻano pauka amorphous keʻokeʻo wai-insoluble me ka maʻemaʻe maʻamau o 99.5% a me 96%. Ma muli o kona kiko heheʻe kiʻekiʻe, ka pale ʻana a me ke kūpaʻa wela, ua hoʻohana nui ʻia ka alumini oxide i ka aerospace, ka ikehu nukelea, ka ikehu, ka metallurgy, nā mea uila, ka ʻenekinia biochemical a me nā papahana ʻē aʻe.

α-Alumina

Hoʻohana ʻia ka alumini oxide no ka hana ʻana i nā ʻano piliki refractory āpau, ka ipu hoʻoheheʻe refractory, ka paipu refractory a me nā mea hana hoʻokolohua e kū ana i ka mahana kiʻekiʻe; ʻo ka alumini oxide ʻano α maʻemaʻe kiʻekiʻe ke kumu maka no ka hana ʻana i ka corundum artificial, ka ruby artificial a me ka sapphire. Hoʻohana ʻia hoʻi ka aluminium oxide no ka hana ʻana i ka papa kaapuni hoʻohui nui o kēia wā.

ʻAlumina wili

He kūpono ke kumukūʻai alumini oxide no nā ʻano hana maloʻo a pulu like ʻole, hiki ke hana i kekahi ʻili paʻakikī o ka workpiece e wili maikaʻi ana, ʻo ia kekahi o nā abrasive hoʻokele waiwai loa.

Alumina i hoʻāla ʻia

ʻO ke kumu kūʻai o ka alumini oxide he ʻāpana porous poepoe keʻokeʻo me ka nui o nā ʻāpana like, ʻili laumania, ikaika mechanical kiʻekiʻe, hygroscopicity ikaika. ʻAʻohe mea ʻawahia ka alumini oxide, ʻaʻohe ʻala, ʻaʻole hiki ke hoʻoheheʻe ʻia i ka wai a me ka ethanol, a he adsorption ikaika no ka fluorine. Hoʻohana nui ʻia ke kumu kūʻai o ka alumini oxide no ka defluorination o ka wai inu ma nā wahi fluorine kiʻekiʻe.

Ma mua: ʻO ka pauka poli alumini oxide i hoʻohana ʻia no ka poli ʻana i ka pena kaʻa

Aʻe: ʻO ka pauka poli alumini oxide no ka pale kelepona paʻalima

1.ʻOihana keramika:Hoʻohana nui ʻia ka pauka alumina ma ke ʻano he mea maka no ka hana ʻana i nā keramika, me nā keramika uila, nā keramika refractory, a me nā keramika ʻenehana holomua.
2.ʻOihana Hoʻopili a me ka ʻAbrasive:Hoʻohana ʻia ka pauka alumina ma ke ʻano he mea hoʻopili a me ka mea abrasive i nā hana like ʻole e like me nā aniani optical, nā wafers semiconductor, a me nā ʻili metala.
3.Hoʻouluulu:Hoʻohana ʻia ka pauka alumina ma ke ʻano he kākoʻo catalyst i ka ʻoihana petrochemical e hoʻomaikaʻi i ka pono o nā catalysts i hoʻohana ʻia i ke kaʻina hana hoʻomaʻemaʻe.
4.Nā Uhi ʻEleʻele Wela:Hoʻohana ʻia ka pauka alumina ma ke ʻano he mea uhi e hāʻawi i ke kūpaʻa i ka pala a me ke komo ʻana i nā ʻili like ʻole i nā ʻoihana aerospace a me nā ʻoihana kaʻa.
5.Palekana Uila:Hoʻohana ʻia ka pauka alumina ma ke ʻano he mea hoʻokaʻawale uila i nā mea uila ma muli o kona ikaika dielectric kiʻekiʻe.
6.ʻOihana Refractory:Hoʻohana ʻia ka pauka alumina ma ke ʻano he mea refractory i nā noi wela kiʻekiʻe, e like me nā uhi umu, ma muli o kona kiko heheʻe kiʻekiʻe a me ke kūpaʻa wela maikaʻi loa.
7.Mea hoʻohui i loko o nā Polymers:Hiki ke hoʻohana ʻia ka pauka alumina ma ke ʻano he mea hoʻohui i loko o nā polymers e hoʻomaikaʻi i ko lākou mau waiwai mechanical a me thermal.
