ipu hoʻoheheʻe keramika Alumina
ʻIke Huahana
ipu hoʻoheheʻe keramika aluminahe pahu hoʻokolohua kū i ka mahana kiʻekiʻe a me ka palaho i hana ʻia me ka alumina maʻemaʻe kiʻekiʻe (Al₂O₃) ma ke ʻano he mea maka nui ma o kahi kaʻina hana kikoʻī. Hoʻohana nui ʻia ia i nā wahi hoʻokolohua wela kiʻekiʻe ma nā kahua o ke kemika, metallurgy, a me ka ʻepekema mea.
Nā Hiʻohiʻona:?
Maʻemaʻe kiʻekiʻe:ʻO ka maʻemaʻe o ka alumina i loko o nā ipu hao keramika alumina he 99% a ʻoi aku paha, e hōʻoiaʻiʻo ana i ke kūpaʻa a me ka inertness kemika i nā mahana kiʻekiʻe.
Ke kūpaʻa wela kiʻekiʻe:ʻO kona kiko heheʻe he 2050℃ ke kiʻekiʻe, hiki i ka mahana hoʻohana lōʻihi ke piʻi i 1650℃, a hiki iā ia ke kū i nā mahana kiʻekiʻe a hiki i 1800℃ no ka hoʻohana pōkole.
Ke kūpaʻa ʻana i ka palaho:He kūpaʻa ikaika kona i nā mea ʻino e like me nā waikawa a menā alkalis, a hiki ke mālama i ka hana paʻa i nā ʻano kemika ʻino like ʻole.
Ke alakaʻi wela kiʻekiʻe:Hiki iā ia ke alakaʻi koke a hoʻopuehu i ka wela, e kāohi pono i ka mahana hoʻokolohua, a hoʻomaikaʻi i ka pono o ka hoʻokolohua.
Ikaika mīkini kiʻekiʻe:He ikaika mechanical kiʻekiʻe kona a hiki ke kū i ke kaomi waho nui me ka ʻole o ka hōʻino maʻalahi ʻia.
Ka helu hoʻonui wela haʻahaʻa:Hoʻemi i ka pilikia o ka haki ʻana a me ka hōʻino ʻia e ka hoʻonui ʻana a me ka ʻūmiʻi ʻana o ka wela.
Maʻalahi e hoʻomaʻemaʻe:He laumania ka ʻili a maʻalahi hoʻi e hoʻomaʻemaʻe me ka ʻole o ka haumia ʻana i ka laʻana, e hōʻoiaʻiʻo ana i ka pololei o nā hopena hoʻokolohua.

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.
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.
