Material Composition

Composite rock wool board is composed of galvanized thin steel plate, PVC plastic decorative film, adhesive and rock wool composite. Specifically, the composite rock wool board is a kind of rock wool in the middle of two layers of 0.7mm thick galvanized steel plate, lining a certain thickness of rock wool, the weight of composite rock wool board per square is 19kg. The connection form between plates is the form of A-type plate and C-type plate.

System Structure

The system structure of composite rock wool board is mainly composed of: bonding layer, thermal insulation layer, plastering layer, finishing layer and accessories.

The bonding layer is attributed to the building, is between the bottom layer and the surface layer, the primary use of cementitious materials to the upper and lower layers of the two layers firmly bonded together, and its filler is mainly derived from inorganic materials.

Insulation layer to avoid and reduce the turbine heat loss to the environment, in the turbine and pipeline and other external laying of insulation material layer, the main filler for the rock wool fibre and a certain amount of organic matter, moisture, and adhesives.

Finish layer should be selected with finishing mortar, embellishment mortar and other lightweight functional coating or water-based exterior coating with outstanding permeability, so that the composite rock wool board to maintain its lightweight characteristics, but also increase its aesthetic degree.

Accessories are mainly used in various types of paint, on the one hand, to increase the surface of the composite rock wool board colour, so that it can be applied to any environment and paint can be a certain degree of flame retardant as well as thermal insulation role.
