ʻO Mullite Brick kahi ʻano o nā refractory kiʻekiʻe alumini e manaʻo nei i ka mullite (Al2O3•SiO2) ma ke ʻano he aniani nui. ʻO ka maʻamau alumina ma waena o 65% a me 75%. Ma waho aʻe o ka mullite mineral haku mele, aia i loko o ka alumina haʻahaʻa he wahi liʻiliʻi o ke aniani a me ka cristobalite; alumina kiʻekiʻe i loaʻa kahi ʻāpana corundum. ʻO ka refractoriness kiʻekiʻe a hiki i 1790 ° C. Hoʻomaka ka hoʻoulu ʻana i ka wela 1600 ~ 1700 °C. Ka ikaika compressive lumi wela 70 ~ 260MPa. Kūleʻa haʻalulu wela maikaʻi. Hoʻohana ka mullite brick i ka corundum plate i lawe ʻia mai a me ka corundum fused kiʻekiʻe ma ke ʻano he kumu kumu, a hoʻohana i ka ʻenehana hoʻohui ultrafine pauda. Ma hope o ka hui ʻana, hoʻomaloʻo a hoʻokumu ʻia, puhi ʻia i loko o kahi kiln kaʻa wela wela.

FAQ
Q: He mea hana ʻoe?
A: ʻAe, he hale hana mākou ma Kina. ʻO kā mākou hale hana e uhi ana i kahi ʻāpana o 30,000 square meters, loaʻa iā ia kahi hoʻonohonoho piha o nā lako hana hou, ʻelua mau kumu hana nui me ka hydro-metallurgy, ʻelua mau hale hana nui a me kahi keʻena hoʻāʻo me nā mea noiʻi nui.
Q: He aha ke ʻano o nā ʻōlelo uku āu e ʻae ai?
A: No ke kauoha liʻiliʻi, hiki iā ʻoe ke uku e T /T, Western Union a i ʻole Paypal, kauoha maʻamau e T /T a i ʻole LC i kā mākou moʻokāki hui.
Nīnau: Hiki iā ʻoe ke hāʻawi mai iaʻu i ke kumu kūʻai hoʻemi?
A: ʻOiaʻiʻo, pili ia i kāu nui.
Q: Pehea e hiki ai iaʻu ke loaʻa kahi laʻana?
A: Loaʻa nā hōʻailona manuahi, akā aia nā uku ukana ma kāu moʻokāki a e hoʻihoʻi ʻia nā uku iā ʻoe a i ʻole e unuhi i kāu kauoha i ka wā e hiki mai ana.
