Aluminum oxide polihing pauda i hoʻohana ʻia no ka hoʻoliʻi ʻana i ka pena kaʻa
ʻO ka pauka alumina he mea maʻemaʻe kiʻekiʻe, maikaʻi i hanaʻia mai ka alumini oxide (Al2O3) i hoʻohana nuiʻia i nāʻanoʻoihanaʻoihana.ʻO ia ka pauka crystalline keʻokeʻo i hana maʻamau ma o ka hoʻomaʻemaʻe ʻana i ka ʻaila bauxite.
Loaʻa i ka pauka alumina nā ʻano waiwai i makemake ʻia, me ka paʻakikī kiʻekiʻe, ke kūpaʻa kemika, a me ka insulation uila, e lilo ia i mea waiwai i nā ʻoihana he nui.
Hoʻohana maʻamau ia ma ke ʻano he mea maka no ka hana ʻana i nā ceramics, refractory, abrasives, a me ka hana ʻana i nā ʻāpana uila like ʻole, e like me nā insulators, substrates, a me nā ʻāpana semiconductor.
I ka lāʻau lapaʻau, hoʻohana ʻia ka pauka alumina i ka hana ʻana i nā mea kanu niho a me nā mea hoʻopili orthopedic ʻē aʻe ma muli o kona biocompatibility a me ke kū'ē ʻana i ka corrosion.Hoʻohana ʻia ia ma ke ʻano he polishing agent i ka hana ʻana i nā lens optical a me nā mea kikoʻī ʻē aʻe.
Ma keʻano holoʻokoʻa, ʻo ka pauka alumina he mea maʻalahi e loaʻa ai ka hoʻohana nui ʻana i ka nui o nā noi ʻoihana ma muli o kāna hui kūʻokoʻa o nā waiwai kino a me nā kemika.

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.
