Nā Pōpō Wili Alumina
Wehewehe Huahana
Nā pōpō wili alumina,i hana ʻia me ka alumini oxide (Al₂O₃) ma ke ʻano he ʻāpana koʻikoʻi a me ka hoʻohana ʻana i ke kaʻina hana sintering ceramic, he mau pōpō ceramic hana i hoʻolālā kūikawā ʻia no ka wili ʻana, ka wāwahi ʻana, a me ka hoʻopuehu ʻana i nā mea. ʻO lākou kekahi o nā mea wili i hoʻohana pinepine ʻia i nā noi wili ʻoihana (e like me nā ceramics, nā uhi, a me nā minelala).
Ua hoʻokaʻawale ʻia nā pōpō wili alumina e ko lākou ʻano alumina i ʻekolu ʻano: nā pōpō alumini waena (60%-65%), nā pōpō alumini waena-kiʻekiʻe (75%-80%), a me nā pōpō alumini kiʻekiʻe (ma luna o 90%). Ua māhele hou ʻia nā pōpō alumini kiʻekiʻe i nā papa 90-ceramic, 92-ceramic, 95-ceramic, a me 99-ceramic, me 92-ceramic ka mea i hoʻohana nui ʻia ma muli o kāna hana holoʻokoʻa kiʻekiʻe. Loaʻa i kēia mau pōpō wili ka paʻakikī kiʻekiʻe (paʻakikī Mohs o 9), ka nui o ka density (ma luna o 3.6g/cm³), ke kūpaʻa i ka ʻaʻahu a me ka palaho, a me ke kūpaʻa wela kiʻekiʻe (1600°C), e kūpono ai no ka wili maikaʻi ʻana o nā glazes seramika, nā mea maka kemika, a me nā minelala metala.
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.

ʻO Shandong Robert New Material Co., Ltd.Aia ma ke kūlanakauhale ʻo Zibo, ka moku ʻo Shandong, Kina, he kahua hana mea refractory. He ʻoihana hou mākou e hoʻohui i ka noiʻi a me ka hoʻomohala ʻana, ka hana ʻana, ke kūʻai aku ʻana, ka hoʻolālā a me ke kūkulu ʻana i ka umu, ka ʻenehana, a me ka hoʻokuʻu aku i nā mea refractory. Loaʻa iā mākou nā lako piha, nā ʻenehana holomua, ka ikaika loea ikaika, ka maikaʻi o ka huahana maikaʻi loa, a me ka inoa maikaʻi. Uhi kā mākou hale hana ma mua o 200 ʻeka a ʻo ka hopena makahiki o nā mea refractory i hoʻohālikelike ʻia he 30000 tons a ʻo nā mea refractory i hoʻohālikelike ʻole ʻia he 12000 tons.
ʻO kā mākou huahana nui o nā mea refractory:nā mea kūpaʻa alkaline; nā mea kūpaʻa silicon alumini; nā mea kūpaʻa ʻano ʻole; nā mea kūpaʻa wela insulation; nā mea kūpaʻa kūikawā; nā mea kūpaʻa hana no nā ʻōnaehana hoʻolei mau.
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.
