Alumina hollow sphere brick from Jundao manufacturer

详情

Alumina hollow sphere brick with fused corundum, sintered alumina and industrial alumina as the main raw material, made of fire and refractory products, with acid and alkali resistance and resistance to the ability of strong, good thermal shock resistance characteristics. It can be used in the following long-term use ***0 ℃. The foaming method and the burning method are two kinds of foaming method. The foam method is prepared by using the rosin soap and the fine raw material and the binder. The foam slurry is cast, molded, dried, sintered, shaped and checked. Foam production of the product, with a uniform structure, low thermal conductivity, well insulation properties. Burning method is the use of polystyrene balls for burning incense to make alumina insulation refractory bricks.
 
Alumina hollow sphere brick body light, pressure strength, low thermal conductivity, heavy volume shrinkage rate, thermal shock stability, and can be used for high temperature thermal insulation equipment or flame directly with the role of the furnace and The work of precision thermal equipment is lined, but it should not be used for direct contact with the erosion of the furnace and slag. In the use of reducing the atmosphere also has a high stability. The use of temperature as the product is generally low purity up to ********0 ℃.
