Nā Piliki Mullite Māmā
ʻIke Huahana
ʻO nā ʻāpana nui onā pōhaku mullite māmāe komo pū me ka alumini oxide (Al₂O₃) a me ka silicon dioxide (SiO₂), a ʻo kona pae kristal nui ʻo mullite (3Al₂O₃·2SiO₂). I ka wā o ke kaʻina hana, hoʻohana pinepine ʻia kahi mea hoʻohua a me kahi mea hoʻopaʻa e kāwili i ka slurry, a ma hope o ka ninini ʻana, ka hoʻōla ʻana, ka maloʻo ʻana, ka hoʻomoʻa ʻana a me ke ahi ʻana, ua hana hope ʻia kahi piliki māmā me ka porosity kiʻekiʻe.
Nā Hiʻohiʻona:
Kiʻekiʻe ka refractoriness:ʻO ka maʻamau, ʻoi aku ka refractoriness ma mua o 1600°C, e mālama ana i nā waiwai kino a me nā kemika paʻa i nā wahi wela kiʻekiʻe.
Ka hoʻokele wela haʻahaʻa:Ma muli o kona ʻano māmā, haʻahaʻa kona conductivity thermal, maʻamau ʻo 0.1-0.2 W/(m·K), e hōʻemi pono ana i ka nalowale wela a hoʻomaikaʻi i ka pono o ka ikehu thermal.
Ikaika kiʻekiʻe a me ka haʻahaʻa haʻahaʻa:ʻO ka maʻamau, ʻo ka nui o ka nui mai 0.5-1.3 g/cm³, e hoʻemi ana i ke kaumaha o ke kūkulu ʻana me ka mālama ʻana i ka ikaika kiʻekiʻe.
Ke kūpaʻa haʻalulu wela maikaʻi loa:Kūpaʻa i nā loli wikiwiki o ka mahana, kūpaʻa i ka nahā ʻana i ka wā e hoʻomaka pinepine ai a pani ʻia ai ka umu, a mālama i ke kūpaʻa o ke kūkulu ʻana.
Ke kū'ē kemika:ʻO ke kūpaʻa maikaʻi loa i nā ʻōpala a me nā kinoea waikawa a me ka alkaline, e hiki ai ke hoʻohana lōʻihi i nā wahi ʻino.
Ka nui o ka haumia haʻahaʻa:Hoʻohana ʻia nā mea maka maʻemaʻe kiʻekiʻe i ke kaʻina hana, e hopena ana i kahi haʻahaʻa o ka haumia, kahi e hōʻemi ai i ka haumia o ka huahana i nā wahi wela kiʻekiʻe.

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.
Hoʻohana nui ʻia nā huahana a Robert i nā umu wela kiʻekiʻe e like me nā metala ʻaʻole ferrous, ke kila, nā mea kūkulu hale a me ke kūkulu ʻana, nā kemika, ka mana uila, ka puhi ʻana i nā ʻōpala, a me ka mālama ʻana i nā ʻōpala weliweli. Hoʻohana ʻia hoʻi lākou i nā ʻōnaehana kila a me ka hao e like me nā ladles, EAF, nā umu pahū, nā mea hoʻololi, nā umu coke, nā umu pahū wela; nā umu metallurgical ʻaʻole ferrous e like me nā reverberators, nā umu hoʻemi, nā umu pahū, a me nā umu rotary; nā umu ʻoihana mea kūkulu hale e like me nā umu aniani, nā umu sima, a me nā umu keramika; nā umu ʻē aʻe e like me nā paila, nā mea puhi ʻōpala, ka umu kālua, i loaʻa nā hopena maikaʻi i ka hoʻohana ʻana. Hoʻokuʻu ʻia aku kā mākou huahana i Asia Hikina Hema, Asia Waena, Hikina Waena, ʻApelika, ʻEulopa, ʻAmelika a me nā ʻāina ʻē aʻe, a ua hoʻokumu i kahi kahua hana like maikaʻi me nā ʻoihana kila kaulana he nui. Ke kakali nei nā limahana a pau o Robert i ka hana pū ʻana me ʻoe no kahi kūlana lanakila-lanakila.
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.
