· inoa huahana: alumini oxide pauka

· Maʻemaʻe huahana: 99.9%, 99.99%

· Nā hiʻohiʻona huahana: kahi heheʻe kiʻekiʻe, paʻakikī kiʻekiʻe, insulation a me ka pale wela

· Ka laulā noi: hiki ke hoʻohana ʻia ka alumini oxide e like me ka analytical reagent, dehydration of organic solvent, adsorbent, organic reaction catalyst, abrasive, polishing agent, raw material for aluminum smelting, refractory, etc.

ʻO ke kumu kūʻai alumini oxide kahi ʻano o ka pauka amorphous keʻokeʻo keʻokeʻo me ka maʻemaʻe maʻamau o 99.5% a me 96%.Ma muli o kona wahi hoʻoheheʻe kiʻekiʻe, ka insulation a me ka pale wela, ua hoʻohana nui ʻia ka alumini oxide i ka aerospace, nuklea ikehu, ikehu, metallurgy, electronics, biochemical engineering a me nā papahana ʻē aʻe.

α -Alumina

Hoʻohana ʻia ka alumini oxide no ka hana ʻana i nā ʻano ʻano like ʻole o nā ʻano pōhaku refractory, refractory crucible, refractory tube a me nā mea hoʻokolohua pale wela kiʻekiʻe;ʻO ka maʻemaʻe kiʻekiʻe α - type oxide alumini ka mea maka no ka hana ʻana i ka corundum artificial, artificial ruby a me ka sapphire.Hoʻohana pū ʻia ka Aluminum oxide no ka hana ʻana i ka papa kaapuni hoʻohui nui i kēia manawa.

Alumina wili

He kūpono ke kumu kūʻai o ka alumini oxide no nā ʻano hana maloʻo maloʻo a me ka pulu, hiki ke lilo i kahi ʻili o ka workpiece wili maikaʻi, ʻo ia kekahi o ka abrasive waiwai nui.

Alumina ho'āla

ʻO ke kumu kūʻai o ka alumini oxide he mea keʻokeʻo spherical porous me ka nui o ka nui o ka nui, ka ʻili maʻemaʻe, ka ikaika mechanical kiʻekiʻe, ka hygroscopicity ikaika.ʻAʻole ʻawaʻawa ka alumini oxide, ʻaʻohe ʻala, ʻaʻole hiki ke hoʻoheheʻe ʻia i ka wai a me ka ethanol, a he ikaika ka adsorption no ka fluorine.Hoʻohana nui ʻia ke kumukūʻai alumini oxide no ka defluorination o ka wai inu ma nā wahi fluorine kiʻekiʻe.

Mua: Aluminum oxide polihing pauda i hoʻohana ʻia no ka hoʻoliʻi ʻana i ka pena kaʻa

Aʻe: Aluminum Oxide Polishing Powder No ka pale kelepona

1.ʻoihana keramika:Hoʻohana nui ʻia ka pauka alumina ma ke ʻano he mea maka no ka hana ʻana i nā seramika, me nā seramika uila, nā ceramics refractory, a me nā seramika ʻenehana kiʻekiʻe.
2.ʻOihana Hoʻomaʻamaʻa a Abrasive:Hoʻohana ʻia ka pauka alumina ma ke ʻano he mea polishing a abrasive i nā noi like ʻole e like me nā lens optical, semiconductor wafers, a me nā ʻili metala.
3.Catalysis: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 ka hana hoʻomaʻemaʻe.
4.ʻO nā uhi hoʻoheheʻe wela:Hoʻohana ʻia ka pauka alumina ma ke ʻano he mea uhi no ka hoʻolako ʻana i ka corrosion a me ke kūʻē ʻana i nā ʻano like ʻole o ka aerospace a me nā ʻoihana automotive.
5.Hoʻokohu uila:Hoʻohana ʻia ka pauka alumina ma ke ʻano he mea insulation uila i nā mea uila ma muli o kona ikaika dielectric kiʻekiʻe.
6.ʻOihana Hoʻomaʻamaʻa:Hoʻohana ʻia ka pauka alumina ma ke ʻano he mea refractory i nā noi wela kiʻekiʻe, e like me nā linings umu, ma muli o kona wahi hoʻoheheʻe kiʻekiʻe a me ke kūpaʻa wela maikaʻi.
7.Hoʻohui i nā Polymers:Hiki ke hoʻohana ʻia ka pauka alumina ma ke ʻano he mea hoʻohui i nā polymers e hoʻomaikaʻi ai i kā lākou mau mea mechanical a me ka wela.
