Thermal Insulation Boards

Insulation Bricks Properties Strong in intensity: The strongest inorganic thermal insulation material in intensity as compared with other nearest density products.Hot-resistant: Not out of shape under the service temperatureWater-resistant: Strong in intensity wet or dryThermal insulation: The lower thermal conductivity than other hard mass thermal insulation materials.Major Applications Lining for industrial furnaces(heating furnace, soaking pit, metallurgy industry)Cooling machine in cement kilnGlass furnacePottery kilnPetrochemical industryHigh temperature flue in metallurgy industryPower plantsShipyardsPaper millsBanking material of refractory bricksElectrolyzing cell in nonferrous metal industry Advantages Temperature range 900oC to 1100oCExceptional strengthLow thermal conductivityEasy application: Available sizes and shapes reduce the number of required joints and makeCalcium silicate easy to work withEnergy saving: Low thermal conductivity provides significant energy savings.Adaptable: Calcium silicate can also be used on a various shapes and sizes of surfacesFire resistantLow chloride contentAsbestos-free Properties IS 9428 1993 limit Calcium Thermal 950 observed Calcium thermal 1100 observed Temperature(oC), max, service temperature oC 950 950 1100 Bulk Density (kg/m3), day 220-280+10% 256 270 Compressive strength, reduction in thickness Not to exceed under a load of Dry, 415kN/m2, Wet, after 18 hrs, immersion in water, 170kN/m2 5% 5% 1.1% 1.3% 0.6% 0.9% Flexural strength(kN/m2), min 240 430 680 Cold crushing strength, kN/m2, min 720 1350 Hot resistance under heat soaking for 24hrs Linear shrinkage (length), max at 950oC Linear shrinkage (length), max at 1050oC Loss in mass, max Compressive strength, reduction in thickness not to exceed under a load of 345 kN/m2 2% 15%  5% 1.5% 11.5% 2.4% 1.2% 9.5% 1.7% Thermal conductivity(W/m K), maximum At mean temperature 200oC 0.080 0.070 0.070 250oC 0.088 0.073 0.074 300oC 0.097 0.079 0.080 350oC 0.110 0.086 0.088 400oC 0.121 0.093 0.095 450oC 0.135 0.096 0.098 500oC 0.148 0.102 As dispatched, moisture content (%), max 7.5 5.5 5.2 Alkalinity, pH 8-11 10 10 Dimensional tolerance(mm) Length/width Thickness +3 -1.5, +3 +2 -1.5, +2 +2 -1.5, +2
