Structure of rock wool sandwich board


●  upper and lower surface: the galvanized color steel plate is used, the thickness is 0.4-0.8mm. In accordance with the specific requirements of the customer, aluminum plated zinc colored steel plate or galvanized steel plate can also be used. The steel plate is rolled and formed by the molding machine first, and it is combined with the rock wool factory.


●  rock wool core material: the density is 120kg/m³ the rock wool block is interlaced and laid on the upper and lower surfaces of the sandwich panel, and the fibers are closely connected to enrich the entire longitudinal plane of the sandwich panel. Between the rock wool and rock wool block between the upper and lower layer plate by high strength adhesive foaming agent and the formation of the overall, sophisticated production process produce strong adhesion energy between the inner wall of high density rock wool heat insulator and metal plate, so that the rock wool sandwich panel has good stiffness.
