Background
The expanded perlite is a natural acidic vitreous lava, a nonmetallic mineral product, and comprises perlite, pitchstone and obsidian, and the perlite, the pitchstone and the obsidian are different only in crystal water content. Since the volume of the expanded perlite is rapidly expanded by 4 to 30 times under the high temperature condition of 1000 to 1300 ℃, the expanded perlite is called as expanded perlite. The heat conductivity coefficient at normal temperature is 0.0245-0.048W/(m.K), the heat conductivity coefficient at high temperature is 0.058-0.175W/(m.K), the heat conductivity coefficient at low temperature is 0.028-0.038W/(m.K), and the maximum use temperature is 800 ℃. The composite material is used as a high-efficiency heat-preservation and cold-insulation filling material, and can improve the heat insulation effect of a heat-preservation material. Expanded perlite passes through the base cloth layer and the division board is separated to fill the filling space through the foaming polyurethane, improved expanded perlite's stability, use it in the heated board, improved the thermal insulation performance of heated board greatly.
