The system structure of rock wool composite board is mainly composed of: bonding layer, thermal insulation layer, plastering layer, finishing layer and accessories.
The bonding layer is between the bottom layer and the surface layer. The upper and lower layers are firmly bonded together with cementing materials. Its filler mainly comes from inorganic substances.
To avoid and reduce the heat loss of steam turbine to the environment, the thermal insulation layer laid on the outer surface of steam turbine and pipeline is mainly filled with a certain amount of organic matter, water, adhesive, etc.
The finishing layer shall be light functional coating such as finishing mortar and decorative mortar or water-based exterior wall coating with excellent permeability, so that the rock wool composite board can maintain its lightweight characteristics and increase its aesthetics.
The accessories are mainly made of various kinds of paints. On the one hand, the color of the surface of the rock wool composite board is increased to make it suitable for any environment. On the other hand, the paint can also play the role of flame retardant and heat preservation to a certain extent.
