Acid-resistant Borosilicate Cellular Glass Brick

--Acid-resistant borosilicate cellular glass is the only light-weighted insulation with 100% waterproofing property. Its water permeability is 0.00 and closed cell 100%. It can guarantee permanently reliable heat conservation result. This material is completely incombustible itself and won't cause any poisonous gas, as a result, it is a safe fireproof material to human absolutely; --Acid-resistant borosilicate cellular glass is a kind of inorganic silicate with closed cells. It has excellent properties: low density, high strength, low thermal conductivity, no water absorption, vapor impermeability, incombustibility, protection form worm, resistant to acid and alkali (except hydrofluoric acid), no toxin, no radioactivity, chemically stable, easy to cut and no deformation, etc. Technical Properties: PROPERTYUNITBS 150BS 200ColorBlackBlackRaw MaterialQuartz SandQuartz SandDensitykg/m3180±10190±10Thermal Conducctivity (20°C)W/m.K0.0560.058Ratio of Water AbsorptionVol%≤0.2≤0.2Compressive Strength 110°C±5°Cx24hMPa≥1.5≥2.0Flexural Strength 110°C±5°Cx24hMPa≥1.2≥1.7Coefficient of Linear Thermal Expansion1/°C6.0×1066.0×106Service Temperature°C-196 +450-196 +450Combustibility--A Grade Non- combustibleA Grade Non- combustibleAcid Fastness(Dip in 40% Sulfuric acid for 30 days at ambient Temp.)--≥0.95 No impact on strength≥0.95 No impact on strengthHeat Resistance (250°CX4h)--≥0.95≥0.95Water Resistance (Dip in water for 30 days at ambient Temp.)--≥0.90≥0.90Durable Years-->30 years>30 years Product TypeUnitBS105BS115BS120BS130BS140BS150BS160BS200Ave.Densitykg/m3105115120130140150160200Ave.Thermal Conductivity (10°C)W/(m·K)0.0390.04250.0430.0440.0460.0470.0480.065Ave.Compressive StrengthMPa0.50.70.81.01.21.41.62.4Chloride Contentppm≤25Water AbsorptionVol%≤0.5Service Temp.°C-268 +480Lineal Expansion Coefficient1/°C9×10-6
