硅酸钙隔热制品是继膨胀珍珠岩、岩棉和矿棉之后的第三代保温隔热材料，它是以钙质和硅质原料，在一定的温度、压力的水热条件下，合成特定类型的含水硅酸钙，并配加一定的增强材料，制成各种固定形状的硬质保温材料；它具有容重轻、导热率低、使用温度高、不溶于水、受潮后再? Calcium silicate thermal insulation products are the third generation of thermal insulation materials following the expansion of perlite, rock wool and mineral wool. They are synthesized from calcareous and siliceous materials under certain conditions of temperature and pressure under hydrothermal conditions. A specific type of hydrous calcium silicate is formulated with a certain amount of reinforcing material to form a rigid insulation material with a variety of fixed shapes; it has a light weight, low thermal conductivity, high operating temperature, insoluble in water and moisture.
