Product Description
High Purity Alumina Bubble Brick Refractory Materials For Insulation Lining
Description:
The product used the alumina hollow ball as the main raw material, high-performance powder as additives, and organic material from the temporary binding agent. After mixing, drying, forming, firing at high temperature shuttle kiln made. The material is widely used in carbon black furnace, gasifier, gas furnace, hydrogen furnace, as well as shuttle kilns and other high-temperature furnace equipment. Products, dimensions, physical and chemical indicators of useful life are up to customer requirements. The company produced lightweight insulation refractory material by its high purity, mechanical strength, and low thermal conductivity.
Applications:
The material can direct contact with flame, anti-spalling, high temperature, and high-temperature industrial furnaces can be used as insulation lining, but also can be used as the work of other industrial high-temperature furnace lining, so the puzzle weight loss, energy-saving and so on.
