ʻO ka pauka alumini Alumina Oxide Powder no ka hoʻopili ʻana i ke aniani kaʻa Optic a me Lens
Hoʻolauna ʻana i ka pauka ʻokikene alumini
He mea maʻemaʻe kiʻekiʻe ka pauka alumina, he mea i hana ʻia mai ka alumini oxide (Al2O3) i hoʻohana nui ʻia i nā ʻano hana like ʻole. He pauka kristal keʻokeʻo ia i hana pinepine ʻia ma o ka hoʻomaʻemaʻe ʻana i ka ore bauxite. Loaʻa i ka pauka alumina nā ʻano waiwai i makemake ʻia, me ka paʻakikī kiʻekiʻe, ke kūpaʻa kemika, a me ka insulation uila, ka mea e lilo ai ia i mea waiwai nui ma nā ʻoihana he nui.

Noi ʻana i ka pauka ʻokikene alumini
1.ʻOihana Ceramic: nā keramika uila, nā keramika refractory, a me nā keramika loea holomua.
2. ʻOihana Polishing a me Abrasive: nā aniani optical, nā wafers semiconductor, a me nā ʻili metala.
3. Hoʻouluulu
4. Nā Uhi ʻEleʻele Wera: nā ʻoihana aerospace a me nā kaʻa.
5. Hoʻokaʻawale Uila
6. ʻOihana Refractory: 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
8. ʻĒ aʻe: ma ke ʻano he uhi hana, nā adsorbents, nā mea hoʻoulu a me nā kākoʻo mea hoʻoulu, ka uhi ʻana i ka vacuum, nā mea aniani kūikawā, nā mea hui pū ʻia, ka mea hoʻopiha resin, nā bio-ceramics etc.
Kāu Nīnau
Inā he mau nīnau kāu. E ʻoluʻolu e hoʻokaʻaʻike mai iā mākou.
