Polyurethane Edge Rock Wool Sandwich Board Thermal Insulation Flame Retardant Composite Board

Introduction

Sandwich panels are used in large industrial plants, warehouses, stadiums, supermarkets, hospitals, cold storage, mobile homes,building plus floors, clean workshops and places where insulation and fire protection are required. The sandwich panel has beautiful appearance, bright color and good overall effect. It integrates load-bearing, heat preservation, fireproof and waterproof, and does not require secondary decoration. It is a kind of versatile, especially in temporary facilities such as offices and warehouses for construction sites. , the wall, etc., more embodies the civilized construction of modern construction sites, especially in terms of rapid installation and use, there are obvious advantages in the detachable and recyclable index of materials that can be installed, and the temporary facilities cost of construction sites is greatly reduced.

Feature

(1) Good insulation performance: Good insulation performance is the basic feature of rock wool products. At room temperature (approximately 25 ℃), their thermal conductivity typically ranges from 0.03 to 0.046 w/(m · k)

(2) Excellent fire resistance: Rock wool itself belongs to inorganic silicate fibers and is not flammable. It has A-level combustion performance and the highest fire resistance, and is classified as a non combustible substance.

(3) Excellent sound insulation performance: Rock wool products have excellent sound insulation and absorption performance. The sound absorption mechanism is that the product has a porous structure. When sound waves pass through, friction is generated due to the effect of flow resistance, so some of the sound energy is absorbed by the fibers, which hinders the propagation of sound waves.
