Awọn biriki Aluminiomu Magnesia
apejuwe
Magnesia-alumina biriki: Magnesia alumina spinel biriki jẹ ifasilẹ alkali pẹlu periclase ati spinel gẹgẹbi awọn ohun alumọni akọkọ, eyiti o jẹ ti iṣelọpọ agbara-titẹ ati iwọn otutu giga.Ni akoko kanna, mineralizer kan pato ti wa ni afikun lati darapọ taara awọn patikulu alakoso gara ti ọja naa.
Awọn ẹya ara ẹrọ
O jẹ ijuwe nipasẹ resistance ipata kemikali otutu otutu, resistance alkali ti o dara julọ, iwọn otutu rirọ fifuye giga, iduroṣinṣin mọnamọna gbona ti o dara, resistance ogbara to lagbara, ati iṣẹ iṣẹ otutu giga ti o dara.
Ohun elo
O jẹ lilo ni akọkọ ni agbegbe iyipada oke ati isalẹ ti kiln rotari simenti ati ohun elo kiln ti o nilo resistance otutu otutu ati resistance mọnamọna ooru.
