Poepoe wili alumina
Hōʻike huahana
Alumina wili poepoe,i hana ʻia me ka alumini oxide (Al₂O₃) ma ke ʻano he kumu nui a me ka hoʻohana ʻana i ke kaʻina sintering seramika, he mau pōpō seramika hana i hoʻolālā ʻia no ka wili, ʻokiʻoki, a me ka hoʻopuehu ʻana i nā mea. ʻO lākou kekahi o nā mea wili wili maʻamau i hoʻohana ʻia i nā noi wili ʻoihana (e like me nā seramika, nā uhi, a me nā minela).
Hoʻokaʻawale ʻia nā pōpō wili alumina e ko lākou ʻano alumina i ʻekolu mau ʻano: nā pōpō alumini-medium (60% -65%), nā pōpō alumini-kiʻekiʻe-kiʻekiʻe (75% -80%), a me nā pōpō alumini kiʻekiʻe (ma luna o 90%). Hoʻokaʻawale hou ʻia nā pōpō alumini kiʻekiʻe i 90-ceramic, 92-ceramic, 95-ceramic, a me 99-ceramic grades, me ka 92-ceramic ka mea i hoʻohana nui ʻia ma muli o kāna hana holoʻokoʻa. ʻO kēia mau pōpō wili e hōʻike ana i ka paʻakikī kiʻekiʻe (Mohs hardness o 9), kiʻekiʻe kiʻekiʻe (ma luna o 3.6g/cm³), ka lole a me ka pale ʻana i ka corrosion, a me ke kūpaʻa wela kiʻekiʻe (1600 ° C), e kūpono ia no ka wili maikaʻi ʻana i nā aniani seramika, nā mea kemika, a me nā minerala metala.
Nā hiʻohiʻona:
Paʻa kiʻekiʻe a me ka pale ʻana i ka ʻaʻahu:ʻO ka paʻakikī o Mohs hiki i ka 9 (kokoke i ke daimana), me ka haʻahaʻa haʻahaʻa haʻahaʻa (<0.03% / 1,000 mau hola no nā kumu hoʻomaʻemaʻe kiʻekiʻe). Kū'ē ia i ka brittleness a me ka ʻōpala i ka wā wili lōʻihi, e hopena i ke ola lawelawe lōʻihi.
Kiʻekiʻe kiʻekiʻe a me ke kiʻekiʻe wili maikaʻi:Me ka mānoanoa nui o 3.6-3.9 g/cm³, hāʻawi ia i ka hopena ikaika a me ka ʻoki ʻana i ka wā wili, hoʻomaʻemaʻe wikiwiki i nā mea i ka pae micron, me ka maikaʻi 20% -30% kiʻekiʻe ma mua o nā pōpō alumini haʻahaʻa.
ʻO nā mea haumia haʻahaʻa a me ka paʻa kemika:Loaʻa i nā kumu hoʻomaʻemaʻe kiʻekiʻe ma lalo o 1% nā mea haumia (e like me Fe₂O₃), e pale ana i ka haumia o nā mea. Kū'ē i ka nui o nā waikawa a me nā alkalis (koe naʻe nā ʻakika ikaika a me nā alkalis), nā wela kiʻekiʻe (ma luna o 800 ° C), a kūpono i nā ʻōnaehana wili like ʻole.
Nā nui hikiwawe a me ke kūpono:Loaʻa i nā anawaena mai ka 0.3 a hiki i ka 20 mm, hiki ke hoʻohana ʻia ka pōleʻa i hoʻokahi a hui pū ʻia paha, kūpono me nā wili pōleʻa, nā wili lepo, a me nā mea hana ʻē aʻe, e hoʻokō i nā pono āpau mai ka wili a hiki i ka wili maikaʻi.

Shandong Robert New Material Co., Ltd.Aia ma Zibo City, Shandong Province, Kina, kahi kumu hana hana refractory. He ʻoihana hou mākou e hoʻohui i ka noiʻi a me ka hoʻomohala ʻana, ka hana ʻana, ke kūʻai aku, ka hoʻolālā kiln a me ke kūkulu ʻana, ʻenehana, a me nā mea refractory hoʻokuʻu aku. Loaʻa iā mākou nā lako piha, nā ʻenehana holomua, ka ikaika ʻenehana ikaika, ka maikaʻi o ka huahana maikaʻi, a me ka inoa maikaʻi. Uhi kā mākou hale hana ma luna o 200 mau ʻeka a ʻo ka puka makahiki o nā mea refractory i hoʻohālikelike ʻia ma kahi o 30000 tons a me nā mea refractory unshaped he 12000 tons.
ʻO kā mākou huahana nui o nā mea refractory:nā mea pale alkaline; aluminika silika refractory mea; nā mea refractory ʻaʻole i hoʻohālikelike ʻia; insulation thermal refractory mea; nā mea refractory kūikawā; nā mea refractory hana no nā ʻōnaehana hoʻolei mau.
Nīnau pinepine
Pono kōkua? E ʻoluʻolu e kipa i kā mākou hui 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. Hoʻohiki mākou e hāʻawi i ke kumukūʻai maikaʻi loa, ʻoi aku ka maikaʻi ma mua o ke kūʻai aku a ma hope o ke kūʻai aku.
No kēlā me kēia kaʻina hana, loaʻa iā RBT kahi ʻōnaehana QC piha no ka haku mele a me nā waiwai kino. A e hoʻāʻo mākou i nā waiwai, a e hoʻouna ʻia ka palapala hōʻoia me nā waiwai. Inā loaʻa iā ʻoe nā koi kūikawā, e hoʻāʻo mākou i ka maikaʻi loa e hoʻokipa iā lākou.
Ma muli o ka nui, ʻokoʻa kā mākou manawa lawe. Akā ke hoʻohiki nei mākou e hoʻouna koke aku me ka maikaʻi i hōʻoia ʻia.
ʻOiaʻiʻo, hāʻawi mākou i nā hōʻailona manuahi.
ʻAe, ʻoiaʻiʻo, ʻoluʻolu ʻoe e kipa i ka hui RBT a me kā mākou huahana.
ʻAʻohe palena, hiki iā mākou ke hāʻawi i ka manaʻo maikaʻi loa a me ka hopena e like me kou kūlana.
Ua hana mākou i nā mea refractory ma mua o 30 mau makahiki, loaʻa iā mākou ke kākoʻo ʻenehana ikaika a me ka ʻike waiwai, hiki iā mākou ke kōkua i nā mea kūʻai aku e hoʻolālā i nā kiln like ʻole a hāʻawi i ka lawelawe hoʻokahi.
