氧化铝空心球制品

氧化铝空心球制品是采用氧化铝空心球为主要原料,高性能刚玉细粉为添加剂,成型干燥后,在1750℃高温窑炉中烧制而成。氧化铝空心球制品具有耐高温,密度小,导热系数低,保温性强,可以提高窑炉使用热效率,减轻炉体重量,降低能耗。


氧化铝空心球制品在航天、原子能、电子工业和新能源等行业广泛的应用。与其它轻质隔热材料相比,氧化物空心球砖隔热材料的特点是安全使用温度高、强度大和热导率小。他们的体积密度比同成分的致密制品低50%~60%,可承受高温火焰的冲击,直接作为高温窑炉的内衬。


Alumina hollow ball products are made by using alumina hollow ball as the main raw material, high-performance corundum fine powder as an additive, molding and drying, and firing in a 1750 ℃ high-temperature furnace. Alumina hollow ball products have high temperature resistance, low density, low thermal conductivity and strong thermal insulation, which can improve the thermal efficiency of the furnace, reduce the weight of the furnace and reduce energy consumption.


Alumina hollow ball products are widely used in aerospace, atomic energy, electronic industry, new energy and other industries. Compared with other lightweight insulation materials, oxide hollow spherical brick insulation materials are characterized by high safe use temperature, high strength and low thermal conductivity. Their bulk density is 50% ~ 60% lower than that of dense products of the same composition, which can withstand the impact of high-temperature flame and can be directly used as the lining of high-temperature kilns.
