Insulating bricks Introduction

Shape with regular insulation products. Are lightweight insulation refractory materials. The common feature of these materials is the volume density, light weight, low thermal conductivity. But lower strength, high-temperature heavy firing shrinkage is large.

Insulating bricks classification.Usually divided into three types: 

• ordinary Insulating bricks, use at temperatures below 1000 ℃, mainly diatomite brick, expansive razor brick, brick, expanded perlite, and more as an insulation layer of thermal equipment. 
• refractory Insulation bricks, using a temperature between 1000-1500 ℃, mainly light clay brick, silica brick lightweight, lightweight aluminum brick and so on. 
• high-temperature Insulating bricks, using a temperature above 1500 ℃, and can be directly used as a high-temperature furnace lining, there are lightweight corundum brick, alumina and zirconia hollow ball products, hollow ball products.
• Ultra-high temperature Insulating bricks, such as by a fibrous silica fibers, alumina fibers, carbon fibers, nitrogen fibers, silicon carbide fibers, at least one heat-resistant inorganic materials such as silica, alumina, lithium oxide, magnesium oxide and clay knot material as raw material, molding and sintering. This brick lightweight, high strength, excellent heat resistance and ultra-high-temperature thermal conductivity, ease of processing, apply to the universe aerospace equipment, industrial kilns and so on.
