Nā Pilikia Mullite Kaumaha Māmā
ʻIkepili Huahana
ʻO nā mea nui onā pōhaku lepo māmāe komo pū me ka alumini oxide (Al₂O₃) a me ka silicon dioxide (SiO₂), a ʻo kona māhele aniani nui he mullite (3Al₂O₃·2SiO₂). I ka wā o ke kaʻina hana, hoʻohana pinepine ʻia kahi mea hoʻoulu a me kahi stabilizer e hoʻohui i ka slurry, a ma hope o ka ninini ʻana, hoʻōla, hoʻomaloʻo, kālua a puhi ʻana, hana ʻia kahi pōhaku māmā me ka porosity kiʻekiʻe. ?
Nā hiʻohiʻona:
ʻO ka refractoriness kiʻekiʻe:ʻOi aku ka refractoriness ma mua o 1600°C, e mālama mau ana i nā waiwai kino a me nā kemika i nā wahi wela kiʻekiʻe.
Haʻahaʻa thermal conductivity:Ma muli o kona ʻano māmā, haʻahaʻa kona conductivity thermal, maʻamau 0.1-0.2 W/(m·K), e hōʻemi pono ana i ka nalowale o ka wela a me ka hoʻomaikaʻi ʻana i ka ikehu wela.
Ka ikaika kiʻekiʻe a me ka haʻahaʻa haʻahaʻa:Mai ka 0.5-1.3 g/cm³ ka mānoanoa nui, e hō'emi ana i ke kaumaha o ke kino me ka mālama 'ana i ka ikaika ki'eki'e.
Kūleʻa haʻalulu wela maikaʻi loa:Kū'ē i nā loli wela wikiwiki, kū'ē i ka pohā i ka wā e hoʻomaka pinepine ai ka umu ahi a pani, a mālama i ka paʻa o ke kūkulu.
Ke kū'ē kemika:Kūleʻa maikaʻi loa i ka ʻakika a me ka alkaline slags a me nā kinoea, hiki ke hoʻohana lōʻihi i nā kaiapuni corrosive.
Haʻahaʻa haumia maʻiʻo:Hoʻohana ʻia nā mea maka maʻemaʻe kiʻekiʻe i ke kaʻina hana, ka hopena i kahi haʻahaʻa haʻahaʻa haʻahaʻa, e hōʻemi ana i ka hoʻohaumia ʻana o ka huahana ma nā wahi wela kiʻekiʻe.

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.
Hoʻohana nui ʻia nā huahana a Robert i nā kiln wela kiʻekiʻe e like me nā metala non-ferrous, ke kila, nā mea kūkulu hale a me ke kūkulu ʻana, kemika, ka mana uila, ka ʻōpala ʻōpala, a me ka mālama ʻino ʻino. Hoʻohana ʻia lākou i nā ʻōnaehana kila a me ka hao e like me nā ladles, EAF, nā kapuahi pahū, nā mea hoʻololi, nā umu coke, nā umu wela wela; nā kapuahi hoʻoheheʻe hao ʻole e like me nā reverberators, nā kapuahi hoʻēmi, nā kapuahi pahū, a me nā kiln rotary; nā mea kūkulu hale kiln ʻoihana e like me nā kiln aniani, nā kiln sima, a me nā kiln seramika; nā kapuahi ʻē aʻe e like me nā paila, nā mea hoʻoheheʻe ʻōpala, ka umu hoʻohala, i loaʻa nā hopena maikaʻi i ka hoʻohana ʻana. Hoʻokuʻu ʻia kā mākou huahana i Asia Hema, Central Asia, Middle East, ʻApelika, ʻEulopa, ʻAmelika a me nā ʻāina ʻē aʻe, a ua hoʻokumu i kahi kumu hana maikaʻi me nā ʻoihana kila kaulana. Ke kakali nei nā limahana a pau o Robert e hana pū me ʻoe no kahi kūlana lanakila-lanakila.
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.
