Nā Pepa Keramika Pale ʻAʻahu Alumina: Nā Hoʻonā ʻAʻahu ʻOihana Hana Kiʻekiʻe

ʻO nā pepa keramika pale ʻaʻahu Alumina he mau mea keramika ʻoihana i hana nui ʻia mai ka alumini oxide (Al₂O₃) a sintered i nā mahana kiʻekiʻe. ʻO ka maʻamau, hiki kēia mau pepa i ka paʻakikī Mohs o 8-9. Ma o nā hoʻolālā ʻili kūikawā, e like me nā ʻili haʻahaʻa i hoʻopōʻino ʻia e hana ana i nā waihona glue grid, nalu, a i ʻole dot-matrix, hoʻonui nui ʻia ka ikaika hoʻopaʻa i nā substrates metala. Hoʻohana ʻia me nā mea hoʻopili keramika-metala kūikawā, hiki i kēia mau pepa ke hana paʻa i nā wahi a hiki i ka 350°C no ka lōʻihi, me kekahi mau huahana e kū ana i nā mahana o 500°C. ʻO ko lākou density ma kahi o 3.6 g/cm³, ʻo ka hapalua wale nō o ke kila, e hōʻemi pono ana i ka ukana o nā lako.

Nā pepa keramika pale ʻaʻahu aluminahāʻawi i ke kūpaʻa ʻana i ka ʻaʻahu ʻokoʻa, me ke ola lawelawe e hiki ke ʻoi aku ma mua o 100 mau manawa o ke kila manganese a ʻoi aku ma mua o 20 mau manawa o ka hao hao kiʻekiʻe-chromium, ma muli o nā kūlana hana. Hoʻohana nā pepa me nā kiko convex a me nā grooves concave i ka hoʻolālā waihona glue, e ʻae ana i ka mea hoʻopili e kahe a hoʻopiha ma lalo o ke kaomi, e hana ana i kahi ʻili hoʻopaʻa serrated e hoʻonui nui i ka hilinaʻi o ka hoʻonohonoho ʻana. ʻO kēia mau ʻano e hoʻohana nui ʻia ai i nā ʻoihana e like me ka mana wela, ke kila, ka sima, a me ka hana mining, ʻoi aku hoʻi no nā wahi i ʻaʻahu nui ʻia e like me nā paipu puka wili lanahu, nā mea hoʻokaʻawale pauka coarse a maikaʻi, a me nā impellers fan.
