Nā Pōpō Wili Alumina
Ma ke ʻano he mea wili seramika hana kiʻekiʻe, ʻo kā mākouNā Pōpō Wili Aluminaua hana ʻia e hāʻawi i ka hana kūikawā i ka wili ʻana, ka wāwahi ʻana, a me nā kaʻina hana hoʻopuehu ma nā ʻāpana ʻoihana like ʻole. Hana ʻia me ka alumini oxide maʻemaʻe kiʻekiʻe (Al₂O₃) ma ke ʻano he ʻāpana koʻikoʻi a me ka ʻenehana sintering ceramic holomua, kū kēia mau pōpō no ko lākou paʻakikī kiʻekiʻe, ke kūpaʻa ʻana i ka ʻaʻahu, a me ke kūpaʻa kemika, e lilo ana iā lākou i koho mua no ka hana ʻana i nā mea pono a pololei.
1. Hoʻokaʻawale ʻana e ka ʻIke Alumina
(1) Nā Pōpō Alumini Waena (60%-65% Al₂O₃):Koho kūpono no ke kumukūʻai no nā hana wili maʻamau. Kūpono no ka wili ʻana i nā mea me ka paʻakikī haʻahaʻa, e like me ka slime lanahu, nā mea hoʻouluulu, a me nā minelala maʻamau. Kūpono no nā mea kūʻai aku e ʻimi nei i ka hana kaulike a me nā hopena kūpono i ke kālā.
(2) Nā Pōpō Alumini Waena-Kiʻekiʻe (75%-80% Al₂O₃):Hoʻonui ʻia ke kūpaʻa ʻana i ka ʻaʻahu i hoʻohālikelike ʻia me nā pōpō alumini waena. Hoʻohana nui ʻia i ka wili ʻana i nā mea maka seramika, nā mea kūkulu hale, a me nā huahana kemika haʻahaʻa-ʻino. He koho maʻalahi no ka wili ʻoihana hana waena.
(3) Nā Pōpō Alumini Kiʻekiʻe (≥90% Al₂O₃):Papa kiʻekiʻe me ka hana piha kiʻekiʻe. Hoʻokaʻawale hou ʻia i nā subgrades 90-ceramic, 92-ceramic, 95-ceramic, a me 99-ceramic. I waena o lākou, ʻo nā pōpō 92-ceramic ka mea kaulana loa ma muli o ko lākou kaulike kūpono o ka hana a me ke kumukūʻai, hoʻohana nui ʻia i ka wili maikaʻi ʻana o nā glazes seramika, nā mea uila, a me nā mea maka kemika maʻemaʻe kiʻekiʻe. Hoʻolālā ʻia nā pōpō 99-ceramic, me ka ʻike alumina kiʻekiʻe loa, no ka wili pololei loa i nā ʻoihana kiʻekiʻe e like me semiconductor a me aerospace.
2. Nā lawelawe hoʻopilikino
Hoʻomaopopo mākou he ʻokoʻa nā pono wili o nā mea kūʻai aku. No ka hoʻokō ʻana i kāu mau koi kikoʻī, hāʻawi mākou i nā lawelawe hoʻopilikino piha:
ʻO ka nui o ka alumina i hoʻopilikino ʻia e kūlike me kāu wahi wili a me nā ʻano o ka mea.
Nā nui maʻamau (mai 1mm a 50mm) a me nā kinona (spherical, cylindrical, a pēlā aku).
Lapaʻau ʻili kūikawā no ka hoʻoikaika ʻana i ke kūpaʻa ʻana i ka ʻaʻahu a i ʻole ka hoʻemi ʻana i ka haumia.
Nā hoʻonā hoʻopili maʻamau (ʻōpala nui, ʻōpala i loko o nā ʻeke, a pēlā aku) e maʻalahi ai ka halihali a me ka mālama ʻana.
Nā Hiʻohiʻona:
Paʻakikī kiʻekiʻe a me ke kūpaʻa ikaika:ʻO ka paʻakikī Mohs e hiki i ka 9 (kokoke i ka daimana), me ka helu haʻahaʻa o ke komo ʻana (<0.03%/1,000 hola no nā hiʻohiʻona maʻemaʻe kiʻekiʻe). Kūʻē ia i ka palupalu a me nā ʻōpala i ka wā wili lōʻihi, e hopena ana i kahi ola lawelawe lōʻihi.
Ka nui o ka density a me ka hana wili kiʻekiʻe:Me ka nui o ka nui o 3.6-3.9 g/cm³, hāʻawi ia i ka hopena ikaika a me nā ikaika ʻokiʻoki i ka wā e wili ai, e hoʻomaʻemaʻe koke ana i nā mea i ka pae micron, me ka pono he 20%-30% kiʻekiʻe ma mua o nā pōpō alumini waena a me ke ʻano haʻahaʻa.
Nā haumia haʻahaʻa a me ke kūpaʻa kemika:ʻO nā hiʻohiʻona maʻemaʻe kiʻekiʻe he emi ma mua o 1% nā haumia (e like me Fe₂O₃), e pale ana i ka haumia o nā mea. Kūpaʻa i ka hapa nui o nā waikawa a me nā alkalis (koe wale nō nā waikawa ikaika a me nā alkalis i hoʻopaʻa ʻia), nā mahana kiʻekiʻe (ma luna o 800°C), a kūpono no nā ʻano ʻōnaehana wili like ʻole.
Nā Nui a me ka Hoʻohālikelike Hiki ke Hoʻololi:Loaʻa i nā anawaena mai 0.3 a 20 mm, hiki ke hoʻohana ʻia ka pōpō i nā nui hoʻokahi a hui pū ʻia paha, kūpono me nā wili pōpō, nā wili one, a me nā lako ʻē aʻe, e hoʻokō ana i nā pono āpau mai ka wili ʻana a hiki i ka wili maikaʻi.

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.
