What materials are rock wool composite boards made of?

Rock wool sandwich panel is a kind of sandwich panel made of rock wool. Rock wool sandwich panels give full play to the unique properties of rock wool core materials, and have significant effects in fire prevention, thermal insulation, sound absorption and sound insulation. So what materials does rock wool composite board consist of?

Composition of rock wool composite board

The structure of rock wool sandwich composite panel is mainly composed of 4 aspects: bonding layer, insulation layer, plastering layer, finishing layer and accessories.

1、 The bonding layer is the architectural layer, which is between the bottom layer and the surface layer. The upper and lower layers shall be firmly bonded together with cementitious materials, and the filler mainly comes from inorganic materials.

2、 In order to avoid and reduce the heat loss of steam turbine to the environment, the thermal insulation material layer laid on the outer surface of steam turbine and pipeline is mainly filled with a certain amount of organic matter, moisture and adhesive.

3、 The finishing layer shall be light functional coating such as finishing mortar and decorative mortar or water-based exterior wall coating with excellent air permeability. In this way, the rock wool composite panel maintains its lightweight characteristics and increases its aesthetics.

4、 The accessories are mainly made of various paints. On the one hand, the color of the surface of the rock wool composite board is increased so that it can be applied to any environment. On the other hand, the paint can also play a role in flame retardant and heat preservation to a certain extent.
