Lightweight clay bricks are made of sillimanite composite as the matrix, mixed with special additives and a small amount of rare earth oxides, and then high-pressure molding and high-temperature firing. Ordinary lightweight heat-insulating refractory bricks are clay, high-aluminum and high-strength floating bead bricks, low-iron mullite, high-aluminum poly-light heat-insulating refractory bricks, and diatomite heat-insulating refractory bricks.
Characteristics of lightweight clay bricks
9. Processability: This product is light and has various specifications and sizes, which is convenient for nailing, drilling, chopping, and using expansion nails on the wall can directly fix hanging cabinets, air conditioners, etc. It will bring convenience to your water and electricity installation and home decoration.
10. Fire resistance: The refractoriness is 700 degrees, which is a Class A1 fire proof material. The fire resistance of 100mm thick blocks reaches 225 minutes, and the fire resistance of 200mm thick blocks reaches 480 minutes.
Clay lightweight insulation bricks have high refractoriness under load, low creep and high thermal shock resistance. It is commonly used in large blast furnaces, hot blast stoves, etc.
