Color steel polystyrene composite board Caigang polystyrene composite panels have vertical and bedroom two modes of production, vertical production is to be made of polystyrene foam beads poured into the pressure plate, then heated and cured a heating temperature of 110-130 ℃, heating time 40-60 minutes, 8-10 minutes cooling time; bedroom production is the use of polystyrene foam board as the core brand of rock wool sandwich panel, and the surface layer by adhesive color plate combined. sandwich panels by automatic continuous composite molding machine Buy wool sandwich panels, outer layer is a high-strength material (eg, color galvanized steel, stainless steel) rock wool sandwich panel, the inner layer is a lightweight insulation material ( flame retardant polystyrene, mineral wool, polyurethane, etc.) by automatic molding machine, with two high-strength adhesive bonding, pressurized, trimming, slotting, blanking from sheet metal. Sandwich only has good insulation, thermal insulation and moisture and other physical properties, but also has good mechanical properties of shear, as a contemporary popular new building materials. Please use rock wool fire retardant plate (glass wool) color steel sandwich.
