General Information
Our silicon insulation brick is made of baked crystalline silica as raw material by adding into compound flammable substance. This product has low thermal conductivity, high refractoriness
under load, residual expansion trace, excellent variability of re-burning line and other characteristics, which is widely available for heat-insulating layer of various high-temperature furnace equipments not in contact with molten slag under high temperature condition (≤1,500 ℃).
With dense and smooth appearance, uniform corner and edge, pure color and luster and accurate size.
1) Silicon oxide is above 95%.
2) Good acid erosion resistance.
3) High softening point with temperature.
4) No shrink in burn repeatedly.
5) Temperature of refractoriness under load is above 1650º C
Typical Application
Light- weight Insulating Brick can be used as a hot surface or other refractory refractory insulation support, used for melting furnace, ignition furnace, flue, refining equipment, heating equipment and piping, regeneration device, gas furnace, soaking furnace, annealing furnace, heat reaction chamber and other industrial equipment.
Advantage of Insulating Brick
Light- weight Insulating Bricks are made from refractory clay as the main raw material of the AL2O3 content is 30% ~ 48% of the heat insulation refractory brick. The production process adopts the burn out of character and bubble method. With refractory clay, drift beads, refractory clay clinker as raw material, adding binder and sawdust, the ingredients, mixing, molding, drying, firing, volume density was 0.8 to 1.5 g/cm3.
