ʻO ka Polycrystalline Al2O3 alumina keramika i hoʻopilikino ʻia ke kūpaʻa wela kiʻekiʻe

Hana keramika alumini oxide

1--Paʻakikī kiʻekiʻe

ʻO ka paʻakikī Rockwell o nā keramika alumina he HRA80-90, ʻo ka lua wale nō i ka paʻakikī ma hope o ke daimana, ʻoi aku ka nui ma mua o ke kila kūpaʻa i ke kapa komo a me ke kila kila kila ʻole.

2--Ke kūpaʻa maikaʻi o ka lole

ʻO ke kūpaʻa o ka ʻaʻahu o nā keramika alumina ua like ia me 266 mau manawa o ke kila manganese a me 171.5 mau manawa o ka hao hoʻolei chromium kiʻekiʻe. Ma lalo o nā kūlana hana like, hiki iā ia ke hoʻolōʻihi i ke ola lawelawe o nā lako ma ka liʻiliʻi he ʻumi mau manawa.

3--Kaumaha Māmā

ʻO ka nui o nā keramika alumina he 3.7 ~ 3.95g/cm°, ʻo ia wale nō ka hapalua o ka hao a me ke kila, a hiki ke hōʻemi nui i ke kaumaha o nā lako.

4--Nā ʻano noi ākea

Hoʻohana nui ʻia nā keramika alumina i nā mīkini, nā optics fiber, nā mea ʻokiʻoki, nā lāʻau lapaʻau, ka meaʻai, ka kemika, ka aerospace a me nā ʻoihana ʻē aʻe.

Nā pōmaikaʻi o nā keramika alumina:

1--He maikaʻi loa nā ʻano insulation o nā keramika alumina. He liʻiliʻi ka pohō alapine kiʻekiʻe, a maikaʻi ka insulation alapine kiʻekiʻe.

2--He kūpaʻa wela ko nā keramika alumina, he coefficient liʻiliʻi o ka hoʻonui wela, ikaika mechanical kiʻekiʻe a me ka conductivity thermal maikaʻi.

3--Loaʻa i nā keramika alumina ke kūpaʻa kemika a me ke kūpaʻa metala hoʻoheheʻe ʻia.

4--ʻAʻole hiki ke lapalapa nā keramika alumina, ʻaʻole maʻalahi ka popo a ikaika a ʻaʻole maʻalahi e hōʻino, me nā mea olaola ʻē aʻe a me nā mea metala ʻaʻole hiki ke hoʻohālikelike ʻia me ke ʻano maikaʻi loa.

5--ʻOi aku ka maikaʻi o ke kūpaʻa ʻana o nā keramika alumina, paʻakikī a me ka corundum like, hiki ke hiki i ka paʻakikī Mohs 9, hiki ke hoʻohālikelike ʻia kona kūpaʻa ʻana me nā mea hoʻohuihui paʻakikī loa.
