The melting temperature of calcium silicate adiabatic production is around 2000°C, the heat-resistant temperature of asbestos rope is 500°C for all asbestos fibers, 250°C for cotton fibers with no more than 10% content, and 350°C for magnesium carbonate filling. The heat-resistant temperature of asbestos cloth is 500°C, the heat-resistant temperature of asbestos yarn is 700°C, and the heat-resistant temperature of asbestos yarn is 500°C. Insulation material industrial equipment and pipelines are insulated with thermal insulation measures and material aerogels, which were first applied to the thermal insulation lining of space suits developed by NASA.
It has the characteristics of low thermal conductivity, low density, high flexibility, fireproof and waterproof. The thermal conductivity at room temperature is 0.018W/(K·m) and is absolutely waterproof. The thermal insulation performance is 3-8 times that of traditional materials. Organic insulation materials mainly include polyurethane foam, polystyrene board, and phenolic foam. Organic thermal insulation materials have the advantages of light weight, good processability, high compactness, and good thermal insulation effect, but the disadvantages are: not resistant to aging, large deformation coefficient, poor stability, poor safety, easy combustion, poor ecological and environmental protection, construction The difficulty is high, the project cost is high, its resources are limited, and it is difficult to recycle.
Traditional polystyrene boards and inorganic insulation boards have excellent insulation effects and are widely used in China's wall insulation materials market, but they do not have safe fire protection performance, especially when they burn to produce poisonous gas.
