By automatic continuous sandwich composite molding machine, rock wool sandwich panel plant, outer layer is a high-strength material (eg, color galvanized steel, stainless steel plate), the inner layer is a lightweight insulation material (flame retardant polystyrene, mineral wool, polyurethane, etc.) by automatic molding machine, thick wool sandwich panels, high-strength adhesive bond between the two, 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 Shear, rock wool sandwich panel, as a contemporary popular new building materials. Please use rock wool fire retardant plate (glass wool) color steel sandwich. On the panel to be divided into two types: metal and nonmetal two panel panel. Metal panels easy processing, can be made into a variety of shapes, but some cases of non-metallic panels with metal panels that fall effects, such as corrosion resistance, impact resistance and other aspects.
