Hiki ke hoʻopili ʻia nā keramika alumina i nā mea hana wela kiʻekiʻe a me ke kapa kiʻekiʻe i ka ʻoihana mana wela

I loko o ka ʻoihana mana wela, ua hōʻino pinepine ʻia nā lako ma muli o ke kaiapuni wela kiʻekiʻe a me nā kūlana ʻaʻahu kiʻekiʻe, kahi e hoʻopilikia ai i ka hana palekana o ka ʻōnaehana holoʻokoʻa. I mea e hoʻoponopono ai i kēia pilikia, pono e ʻimi i nā mea e hiki ke kū i nā mahana kiʻekiʻe a kūʻē i ka ʻaʻahu. He kūpono loa nā mea keramika alumina.

ʻO ka alumina ceramic kahi ʻano alumina (Al2O3) ma ke ʻano he mea maka o ka mea seramika, ma hope o ke kaomi maloʻo ʻana, a laila ma o ka ʻoi aku ma mua o 1,700 degere o ka sintering wela kiʻekiʻe. Loaʻa i nā keramika alumina nā ʻano o ka conductivity maikaʻi, ka ikaika mechanical, ke kūpaʻa wela kiʻekiʻe a me ke kūpaʻa corrosion. I ana ʻia e ka Shanghai Institute of Silicate o ka Chinese Academy of Sciences, ʻo kona paʻakikī Rockwell ʻo HRA80-90, ʻo ka paʻakikī ka lua wale nō i ka daimana, ʻoi aku ka nui ma mua o ke kūpaʻa ʻana o ke kila kūpaʻa a me ke kila kila. ʻO ke kūpaʻa ʻana o ke kapa he 266 mau manawa o ke kila manganese a me 171.5 mau manawa o ka hao hoʻolei chromium kiʻekiʻe. Wahi a kā mākou noiʻi hahai mea kūʻai aku no nā makahiki he ʻumi a ʻoi, ma lalo o nā kūlana hana like, hiki ke hoʻolōʻihi ʻia ke ola lawelawe o nā lako ma ka liʻiliʻi he ʻumi mau manawa.

Hiki ke hoʻohana ʻia nā keramika alumina i nā ʻāpana lako hana wela kiʻekiʻe a me nā mea hana ʻaʻahu kiʻekiʻe i ka ʻoihana mana wela, e like me nā mea pā, nā rotors pamu, nā pūpū, nā paipu, nā noho, nā apo sila, a me nā mea ʻē aʻe. Pono kēia mau ʻāpana e kū i ke kiʻekiʻe o ka mahana, ke kaomi kiʻekiʻe a me nā mea ʻino, no laila pono lākou e hoʻohana i nā mea pale ʻaʻahu maikaʻi e hana ai.

I ka ʻoihana mana wela, ʻo ka wili lanahu ka lako nui, a me ka hoʻohana ʻana onā keramika pale ʻaʻahuhiki ke hoʻomaikaʻi maikaʻi i ke ola lawelawe o ka wili lanahu, a laila e hōʻoia i ka hana o ka ʻōnaehana paila holoʻokoʻa. ʻAʻole hiki i kēia ke hōʻemi wale i ka downtime o ka hāʻule ʻana o nā lako, e hōʻoia i ka hana paʻa o ka ʻōnaehana paila, akā e hōʻemi pū i ke kumukūʻai o ka mālama ʻana i nā lako, kahi e kūlike me ka ʻimi ʻana i nā pono waiwai i ka ʻoihana mana wela.

Pono e hoʻomaopopo ʻia i nā noi hana, pono e koho ʻia nā kikoʻī, ka ʻike, ka hana ʻana a me ka hoʻohana ʻana i nā keramika kūpaʻa e like me nā kūlana hana maoli e hōʻoia i ka hana a me nā hopena maikaʻi loa.
