Introduction to the material characteristics and advantages of alumina hollow sphere products
Alumina hollow spheres and their products are a new type of high-temperature thermal insulation refractory material. It has high strength, good chemical stability, light bulk density, and a large number of closed pores. It is widely used in petroleum, chemical, ceramics, and high-temperature and ultra-high temperature for national defense scientific research. On thermal equipment.
Alumina hollow spheres can be directly used as heat insulation fillers for high-temperature and ultra-high temperature thermal equipment, or they can be made into bricks to build high-temperature and ultra-high temperature electric furnaces. The lining of the furnace can reduce the weight of the furnace body, greatly improve thermal efficiency and shorten The production cycle is an ideal refractory material for energy saving, material saving and high efficiency.
Alumina hollow sphere products are used in the insulation layer (aluminum tile) in quartz glass continuous melting furnaces and tungsten-molybdenum intermediate frequency furnaces. They have the advantages of high strength, high temperature resistance, and chemical corrosion resistance. The maximum operating temperature is 1800°C.
Alumina hollow spheres have obvious thermal insulation properties, low thermal conductivity, can play a very good thermal insulation effect, reduce heat dissipation, improve thermal efficiency, thereby saving energy, and the energy saving effect can reach more than 30%.
