Polyurethane sealing rock wool sandwich panel on both sides give full play to the unique properties of rock wool core material, the fire prevention, heat preservation and heat insulation, sound-absorbing, sound insulation, etc, has a significant effect.
Rock wool core material: the density of 120kg / m3; rock wool block staggered laying, the fiber direction perpendicular to the sandwich is still under the surface, and closely Detailed enrich the entire vertical and horizontal surface movement plate. And wool and, through the high intensity blowing agent connections between the lower plate is formed integrally between rock wool blocks. Sophisticated production process to ensure to produce high density rock wool insulation between the body and the metal plate inside the inner wall of strong adhesion, so that the rock wool sandwich panel has good stiffness.
(1)excellent fireproof performance: the raw material, production technology and formula of the polyurethane sealing rock wool sandwich panel, so that it has good fireproof performance.
(2) sound insulation and sound absorption effect is remarkable: Polyurethane sealing rock wool sandwich panel has a significant reduction effect on noise transmission, especially for designated flights.
(3) remarkable effect in fire prevention, heat preservation, heat insulation, At the same time, it preserves the advantages of polyurethane molding, sealing, high strength and no water absorption.
Polyurethane sealing rock wool sandwich panel widely used in the steel structure factory building, activities room, roof, wall, air clean room ceiling and partition.
