What is the structure of composite rock wool board

Structural composition of composite rock wool board: adhesive layer, thermal insulation layer, plastering layer, decorative layer and accessories. The intermediate layer between the bottom layer and the surface layer is the adhesive layer. Firstly, the upper and lower layers must be fastened with cement Bonded together, followed by filling with inorganic materials.

The insulation layer can reduce the heat loss of the pipeline, and its main fillings are organic matter, moisture, adhesive, etc. The decorative layer is mostly light functional coatings such as decorative mortar or exterior wall paint with outstanding air permeability. The rock wool composite board made in this way has the characteristics of light weight and beautiful appearance.

Accessories are generally various types of coatings. On the one hand, they can change the appearance color of the composite rock wool board. On the other hand, the coatings have a certain degree of flame retardancy and thermal insulation.

The composite rock wool board adds a cement mortar screed on the basis of the rock wool board, which increases the hardness of the rock wool board, which can simplify the construction process and shorten the construction cycle. Rock wool board is made of basalt and other natural ores as the main raw material, melted into fibrous form at high temperature, added an appropriate amount of binder, and cured. Rock wool board is widely used in industrial equipment, construction and other fields, and can be used for heat insulation and sound insulation of ships.
