Fire protection: The surface material and thermal insulation material of the multicoloured composite sandwich panel are non-combustible materials, which can fully meet the requirements of fire protection standards.
Durability: Various studies have shown that the shelf life of colorful steel sheets treated with special coatings is 10-15 years, and after spraying anticorrosive coatings every 10 years, the life of the sheets can reach more than 35 years.
Beauty: Profiled steel plate has clear lines of more than dozens of colors, which can meet the needs of any individual building to achieve a satisfactory effect.
High Strength: The use of high strength steel plate as the base material (tensile strength 5600KG/CM), coupled with the most advanced design and rolling forming, has excellent layout characteristics.
Heat preservation and insulation: The commonly used insulation materials of the composite board are rock wool, glass fiber wool, polyethylene, polyurethane, etc., with low thermal conductivity and excellent heat preservation and insulation effect.
Layout function of rock wool board
The system layout of rock wool board mainly consists of bonding layer, insulation layer, coating layer, decorative layer and accessories.
In order to build the bonding layer, it is between the bottom layer and the surface layer. The first thing is to use cementitious materials to bond the upper and lower layers firmly. The filler of the bonding layer mainly comes from inorganic substances.
In order to avoid and reduce the heat loss of steam turbine to the environment, the insulation material layer is laid on the outer surface of steam turbine and pipeline. Its main filler is rock wool fiber and a certain amount of organic matter, moisture, and adhesive.
The facing layer should be lightweight functional coatings such as decorative mortar and decorative mortar or water-borne exterior wall coatings with outstanding permeability, which can keep the lightweight characteristics of rock wool board and add its aesthetic degree.
Fittings are mainly made of various coatings. On the one hand, the surface color of rock wool insulation board is added, so that it can be applied to any environment and paint can play a role of flame retardant and thermal insulation to a certain extent.
Rock wool board insulation material
In the market of thermal insulation materials, energy-saving materials which can satisfy the requirements of apparent density, use temperature, compressive strength, thermal conductivity and water absorption are mainly polystyrene foam board (EPS and XPS), glass wool, glass wool felt and ultra-light polyphenyl granular thermal insulation slurry. A common feature of all the above materials is that there are a large number of closed holes in the interior of the materials, and their apparent density is small, which is also necessary for thermal insulation materials.
