· 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 ma ke ʻano he analytical reagent, dehydration o ka mea hoʻoheheʻe organik, adsorbent, ka mea hoʻonaninani kūlohelohe, abrasive, polishing agent, maka mea no ka hoʻoheheʻe alumini, 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, insulation a me ka pale wela, ua hoʻohana nui ʻia ka alumini oxide i ka aerospace, ka ikehu nuklea, ka ikehu, ka metallurgy, ka uila, ka ʻenekini biochemical 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 nā mea abrasive ʻoi loa.

Alumina ho'āla

ʻO ke kumu kūʻai o ka alumini oxide he keʻokeʻo spherical porous particle 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 loa.
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.
