Means a lightweight castable volume density of less than 1800kg / m3, the total porosity is greater than 45% shrinkage at a given temperature is less than 1.5% of the castable. Lightweight castable small bulk density, low thermal conductivity Yunnan castable alumina hollow ball, because it has good insulation properties. The most commonly used classification: sand light brick, clinker, porous, hollow ball, perlite and other lightweight ceramic and refractory castable. I produced the high-temperature high-strength lightweight insulation castable do not, you can also do the job lining, long direct contact with the flame, the liquid metal, slag. Use of high-strength wear-resistant castable 1, the power generation industry for coal unloading chute, coal hopper, storage bunker, dry coal gate, dumper, slag, water treatment and so on. 2, the chemical industry, anti-corrosion ground, pump base and so on. 3, wear-resistant lining of the coal industry waste rock storage, medium bucket, scraper, bucket elevator, chute, funnel, etc. within the next screen. 4, the steel industry's blast mixing positions, firing hopper, feeder, make the ball machine. High-strength wear-resistant castable Features 1, high strength, high wear resistance, impact resistance, anti-erosion, anti-oil seepage 2, flame retardant, low water absorption, resistance to high temperature 3, durability, long life 4, The construction is simple, fast, easy to master 5, the overall good, easy to repair Chongqing castable alumina balloons, not falling 6, non-toxic, tasteless, environmental protection, no physical damage to the operator
