JM23 Mullite Insulation Brick Application
JM23 Insulation Brick are widely used for heat-insulating purpose in many kinds of industrial furnace, electric furnace and metallurgical stove,cracking furnace in petroleum, hot blast furnace in metallurgy,ceramic roller kiln, tunnel kiln, shuttle kiln for electrical porcelain,pot furnace for glass industry, Inner lining of kinds of electrial furnaces and high temperature equipment.
JM23 Mullite Insulation Brick Manufacturing Process
There are three methods for producing mullite insulation bricks: foam method, additive burning method and gasification method.
1.First Method of Producing Mullite Insulation Lightweight Bricks
The foamed mullite insulation brick is prepared by mixing a foaming agent, a stabilizer and water in a certain ratio, at first, forming a foaming liquid, and then mixing with the slurry through casting, curing, drying, baking and firing. Which made of high porosity mullite insulation brick.
2.Second Method of Producing Mullite Insulation RefractoryBricks
The addition of the smoldering method to the production of lightweight mullite bricks is to add a portion of the flammable additives, such as wood chips, polystyrene,coke. when the refractory brick is fired, the combustible additive burns rapidly, and the position of the additive becomes a pore. This high-density, low-density fire brick becomes a mullite insulation brick.
3.Third Method of Producing JM23 Mullite Insulation Bricks
Gasification process for producing mullite insulation bricks refers to the introduction in the ingredients. A person can chemically produce a substance that uses a chemical method to obtain gas, thereby producing a fire brick having a high porosity and a low density.
