ʻO ka ʻōwili keramika Alumina
ʻIke Huahana
Nā wili keramika aluminahe mau huahana keramika ʻoihana hana kiʻekiʻe i haku ʻia me ka alumina (Al₂O₃), a he mau ʻāpana koʻikoʻi ia o nā umu wili wela kiʻekiʻe o kēia wā.
Ka Hoʻohui Mea:ʻO ka maʻamau, ʻo ka nui o ka alumina he ≥95% e hōʻoia i ka hana wela kiʻekiʻe maikaʻi loa a me nā waiwai mechanical.
Nā Hiʻohiʻona Huahana:
Paʻakikī Kiʻekiʻe:ʻO ka paʻakikī o Rockwell ʻo HRA80-90, ʻo ka lua wale nō ma hope o ke daimana, ʻoi aku ka maikaʻi ma mua o ke kūpaʻa ʻana o ke kila kūpaʻa a me ke kila kila ʻole.
Ke kūpaʻa maikaʻi loa i ka hoʻohana ʻana:ʻO ke kūpaʻa o ke komo ʻana he like ia me 266 mau manawa o ke kila manganese a me 171.5 mau manawa o ke kila hao kiʻekiʻe-chromium, e hoʻolōʻihi ana i ke ola o nā lako ma ka liʻiliʻi he ʻumi mau manawa.
Māmā:ʻO ka nui o ka mānoanoa he 3.6 g/cm³, hapalua wale nō ia o ke kila, e hoʻemi nui ana i ka ukana o nā lako.
Ke kū'ē ʻana i ka mahana kiʻekiʻe:ʻO ke kūpaʻa wela kiʻekiʻe maikaʻi loa, me ka mahana hana kiʻekiʻe loa o 1600 ℃. I ka manawa like, hōʻike ia i ke kūpaʻa wela hilinaʻi loa a me ke kūpaʻa haʻalulu wela maikaʻi loa no nā huahana i hoʻā ʻia a hiki i 1400 ℃.
Nā kikoʻī:ʻO ke anawaena maʻamau he 12-80mm, ʻo ka lōʻihi he 1200-5300mm, a loaʻa ka hoʻopilikino ʻana e like me nā umu like ʻole a me nā pono hana.
Nā Mālama Hoʻohana:Pono e hoʻopiha ʻia nā lua o loko ma nā wēlau ʻelua o ka wili me ka pulupulu olonā kūpaʻa. Pono e hoʻopili ʻia kahi uhi pale ma mua o ke komo ʻana i loko o ka umu a ʻae ʻia e maloʻo loa. I ka wā e hoʻohana ai, pono e hoʻomaʻemaʻe mau ʻia nā koena o ka ʻili. I ka hoʻololi ʻana i nā wili, e makaʻala i ka wikiwiki a me ke ʻano o ka hoʻomaʻalili ʻana e pale aku i ka pōʻino i hana ʻia e ka hoʻomehana wikiwiki a i ʻole ka hoʻomaʻalili ʻana.

1. ʻOihana Keramika Hoʻolālā Hale:ʻO kēia ka wahi noi nui no nā wili keramika alumina. I ke kaʻina hana puhi ʻana i ka umu wili o nā keramika hoʻolālā e like me nā tile paia, nā tile papahele, nā tile kahiko, a me nā tile ma o ke kino, kākoʻo pololei nā wili i nā blanks keramika, e hoʻokō ana i ka hoʻoili paʻa ma nā mahana kiʻekiʻe (maʻamau 1200–1450 ℃) e hōʻoia i ka hoʻomehana like a me ke ahi ʻana o nā huahana kūpono.
2. ʻOihana Keramika Hoʻohana i kēlā me kēia lā:Hoʻohana ʻia i loko o nā umu ahi wela kiʻekiʻe no nā keramika hoʻohana o kēlā me kēia lā e like me nā kīʻaha, nā pā, nā kīʻaha, a me nā pā liʻiliʻi, a me nā mea hoʻomaʻemaʻe keramika (nā lua, nā poho holoi, a pēlā aku). ʻO nā ʻano hoʻonui wela haʻahaʻa o nā wili e pale ai i ka deformation a i ʻole ka haki ʻana i hoʻokumu ʻia e nā loli wela koke, e hōʻoiaʻiʻo ana i ke ʻano a me ke kūpaʻa o ka maikaʻi o nā huahana keramika hoʻohana o kēlā me kēia lā.
3. ʻOihana Keramika Kūikawā a me nā Mea Paʻakikī:Kūpono no nā umu sintering wela kiʻekiʻe no nā keramika kūikawā ʻoihana (e like me nā insulators keramika, nā blanks mea hana keramika, nā ʻāpana keramika kūkulu), nā piliki refractory, a me nā modula mea refractory. Pono kēia mau noi i ke kūpaʻa wela kiʻekiʻe mai nā wili; hiki i nā wili keramika alumina me ka nui o ka alumina (≥95%) ke kū i nā mahana kiʻekiʻe loa o 1600 ℃.
4. ʻOihana Hana Hohonu Aniani:I loko o nā umu hoʻoheheʻe aniani a me nā lako hoʻoili ʻāpana hoʻomehana no ka hana ʻana i ke aniani i hoʻomaʻamaʻa ʻia, hiki i nā ʻōwili keramika alumina ke pani i nā ʻōwili metala, e pale ana i nā ʻōwili metala mai ka pipili ʻana i ka ʻili aniani i nā mahana kiʻekiʻe. I ka manawa like, ʻo ko lākou kūpaʻa maikaʻi loa i ka ʻaʻahu e hoʻolōʻihi i ke ola o nā lako a hōʻoia i ka laumania o ka ʻili o nā huahana aniani.
5. ʻOihana Keramika Uila:Hoʻohana ʻia i ke kaʻina hana puhi wela kiʻekiʻe o nā ʻāpana keramika uila (e like me nā capacitors keramika, nā keramika piezoelectric, a me nā keramika magnetic). He mau koi koʻikoʻi ko nā keramika uila no ke kūpaʻa o ke kaiapuni puhi. ʻO ka haʻalulu wela haʻahaʻa a me ka inertness kemika o nā wili keramika alumina e pale aku i nā wili iā lākou iho mai ka haumia ʻana i nā ʻāpana keramika, e hōʻoiaʻiʻo ana e hoʻokō nā ʻāpana hana o nā ʻāpana uila i nā kūlana.
Nā Nīnau i Nīnau Pinepine ʻia
Pono kōkua? E kipa aku i kā mākou mau kahua kākoʻo no nā pane i kāu mau nīnau!
He mea hana maoli mākou, ua loea kā mākou hale hana i ka hana ʻana i nā mea refractory no nā makahiki he 30 a ʻoi. Hoʻohiki mākou e hāʻawi i ke kumukūʻai maikaʻi loa, ka lawelawe mua a me ka lawelawe ma hope o ke kūʻai aku.
No kēlā me kēia kaʻina hana, loaʻa iā RBT kahi ʻōnaehana QC piha no ka hoʻohuihui kemika a me nā waiwai kino. A e hoʻāʻo mākou i nā waiwai, a e hoʻouna ʻia ka palapala hōʻoia maikaʻi me nā waiwai. Inā he mau koi kūikawā kāu, e hoʻāʻo mākou i ka maikaʻi loa e hoʻokō iā lākou.
Ma muli o ka nui, ʻokoʻa ka manawa hoʻouna. Akā ke hoʻohiki nei mākou e hoʻouna koke me ka maikaʻi i hōʻoia ʻia.
ʻOiaʻiʻo, hāʻawi mākou i nā laʻana manuahi.
ʻAe, ʻoiaʻiʻo, ua ʻoluʻolu ʻia ʻoe e kipa i ka hui ʻo RBT a me kā mākou huahana.
ʻAʻohe palena, hiki iā mākou ke hāʻawi i ka manaʻo maikaʻi loa a me ka hoʻonā e like me kou kūlana.
Ua hana mākou i nā mea refractory no nā makahiki he 30 a ʻoi, loaʻa iā mākou ke kākoʻo loea ikaika a me ka ʻike waiwai, hiki iā mākou ke kōkua i nā mea kūʻai aku e hoʻolālā i nā kilns like ʻole a hāʻawi i ka lawelawe hoʻokahi.
