Pauka alumina no ka hoʻopili ʻana
ʻO ka pauka alumina ka mea kūpono no ka hana ʻana i ka alumini a me nā mea ʻē aʻe e pono ai ka paʻakikī a me ke kū'ē ʻana i ka abrasion a i ʻole nā ʻano kemika ʻē aʻe. He kūpono nō hoʻi ka pauka alumina no nā huahana e pono ai ke kū'ē i ka pala a me ke komo ʻana, a no nā huahana e pono ai ke alakaʻi wela kiʻekiʻe, e like me nā noi hoʻokaʻawale uila a me ka wela.
Hana huahana:
He pauka keʻokeʻo a he one maikaʻi paha ka huahana a he hana sintering maikaʻi kona. ʻAʻole hiki ke hoʻoheheʻe ʻia i ka wai, ʻaʻole hiki ke hoʻoheheʻe ʻia i ka waikawa a me ka hopena alkali. Hiki ke hoʻokele ʻia ka nui o ka ʻāpana o ka protocrystal.

ʻAno o ka pauka Alumina:
1. Ke kū'ē kemika
2. ʻO ka alumina maʻemaʻe kiʻekiʻe, ʻoi aku ka nui o ka alumina ma mua o 99%
3. Ke kūpaʻa wela kiʻekiʻe, ʻo ka mahana hana he 1600 ℃, a hiki i ka 1800 ℃
4. ke kūpaʻa haʻalulu wela, paʻa a paʻakikī hoʻi e haki
5. Hoʻoheheʻe ʻia ma ke kahakaha ʻana, he kiʻekiʻe kona nui
Loaʻa i ka pauka alumina nā pono o ka maʻemaʻe kiʻekiʻe a me ke kiʻekiʻe o ka density, i hoʻohana nui ʻia i nā keramika, ke aniani, nā plastics, nā textiles, nā mea kūkulu hale, nā abrasives, ka pepa a me nā lāʻau lapaʻau, a me nā ʻoihana ʻē aʻe he nui.
Ka Pōmaikaʻi o ka Pauka Alumina:
1. Ma o ka wili ea a me ka hoʻokaʻawale ʻana o nā papa ʻelima, he haiki ka hoʻokaʻawale ʻana o ka nui o ka palaoa, kiʻekiʻe ka pono o ka wili ʻana, maikaʻi ka hopena polishing, ʻoi aku ka kiʻekiʻe o ka pono o ka wili ʻana ma mua o nā mea abrasives palupalu e like me ka silica.
2. ʻO ke ʻano maikaʻi o nā ʻāpana, ʻo ka ʻili o ka mea e hoʻopili ʻia he kiʻekiʻe ke ʻano o ka laumania, i ke kaʻina hana polishing maikaʻi hope loa, ʻoi aku ka maikaʻi o ka hopena o ka wili ʻana a me ka polishing ma mua o ka pauka corundum keʻokeʻo.
1. Hoʻopili ʻia ka pale kelepona, me ka hoʻopili hope loa no ka pale kelepona sapphire, ka pale aniani kelepona. Hiki ke hoʻohana ʻia: nā pōhaku makamae hana, zircon, ke aniani kiʻekiʻe, nā pōhaku kūlohelohe, jade, agate a me nā hoʻopau haʻalulu ʻē aʻe (polishing mīkini, polishing ʻōwili), polishing lima (polishing wili) a pēlā aku.
2. Ka wili ʻana i nā metala, me ka pūpū kelepona paʻalima, nā huila kaʻa, ka wili hope loa o nā lako paʻa kiʻekiʻe.
3. Hoʻohana nui ʻia i ka wili ʻana a me ka poli ʻana o nā semiconductors, nā kristal, ka alumini, ke kila, ke kila kila, ka pōhaku, ke aniani, a pēlā aku.
4. Kūpono loa no ka wili ʻana a me ka poli ʻana o ke kila kila, ke keleawe, nā mea metala ʻē aʻe, a me ka ʻoihana aniani.
