ʻŌwili Silicon Carbide
Nā wili Silicon Carbide (SiC)ʻo ia nā ʻāpana hoʻoili koʻikoʻi o nā umu wili, i hoʻohana nui ʻia i ke ahi ʻana i nā keramika hoʻolālā hale, nā mea hoʻomaʻemaʻe, nā keramika kūloko, a me nā keramika uila. Ma muli o ke kaʻina hana, ua hoʻokaʻawale nui ʻia lākou i ʻelua ʻano: Reaction Bonded Silicon Carbide (RBSiC) a me Recrystallized Silicon Carbide (RSiC).
Hoʻohālikelike ʻAno:
1. ʻO ka SiC i hoʻopaʻa ʻia (RBSiC):
ʻAno: Loaʻa kahi liʻiliʻi o ka silicon manuahi.
Nā Pōmaikaʻi: Kiʻekiʻe ka nui, ikaika kiʻekiʻe, a me ke kumukūʻai kūpono.
Ka Mahana Loa: A hiki i 1400°C.
Hoʻohana: Kūpono no nā umu wili wela waena a kiʻekiʻe e hoʻā ana i nā tile a me nā keramika home. Hāʻawi i ke kaulike maikaʻi loa o ka hana a me ke kumukūʻai.
2. SiC i hoʻopili hou ʻia (RSiC):
ʻAno: Maʻemaʻe kiʻekiʻe me ka ʻaneʻane ʻole o ka pae hoʻopili.
Nā Pōmaikaʻi: Ke kūpaʻa wela kiʻekiʻe a me ke kūpaʻa kolo (ʻaʻohe deformation i ka wela nui).
Ka Mahana Loa: A hiki i ka 1650°C+.
Hoʻohana: He kūpono no ke kuni ʻana i nā mea hoʻomaʻemaʻe a me nā keramika kūikawā i ka mahana kiʻekiʻe kahi e pono ai ke kūpaʻa wela loa.
Nā Hiʻohiʻona Koʻikoʻi:
1. Ikaika Mahana Kiʻekiʻe Loa:Mālama i nā waiwai mechanical maikaʻi loa ma nā mahana mai 1400°C a 1600°C.
2. Kū'ē Kū'ē Wela Maika'i Loa:Kūpaʻa i nā loli wikiwiki o ka mahana, e pale ana i ka nahā a i ʻole ka haki ʻana i ka wā o ka hoʻomehana wikiwiki a me nā pōʻaiapuni hoʻomaʻalili.
3. Ke kū'ē kiʻekiʻe o ka hoʻohana ʻana:Hoʻolōʻihi i ke ola lawelawe a hoʻemi i nā kumukūʻai mālama i nā wahi umu abrasive.
4. Ke kū'ē ʻana i ka palaho a me ka ʻokikene:Hana maikaʻi i nā lewa umu like ʻole, e pale ana i ka ʻinoʻino kemika.
5. Pololei Ana Kiʻekiʻe:ʻO ka hoʻopau ʻana o ka ʻili laumania e hōʻoiaʻiʻo ai i ka halihali paʻa a pololei o nā huahana seramika.

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.
