The main material of rock wool composite board is basalt cotton board. Basalt, iron ore and bauxite are the main raw materials. The artificial inorganic fiber is made by high temperature melting processing and adding appropriate amount of binder. It has the characteristics of light weight, low thermal conductivity, heat absorption and non combustion.
The density of rock wool composite board is related to the insulation quality of rock wool composite board. The density of rock wool composite board used in different types of walls is also different because of its different fire rating. After adjustment, the density of rock wool composite board will have some impact on noise reduction effect. As a new type of building material, rock wool composite board, together with calcium silicate board and ultra-fine glass fiber, has become the main material of ship interior decoration. The structure of rock wool composite board has four layers, which are bonding layer, insulation layer, plastering layer, facing layer and accessories.
The main source of bonding between the upper layer and the lower layer is the adhesive material between the upper layer and the lower layer. With the development of rock wool composite technology, it will be widely used in the construction industry.
In this process, the air pressure also plays a key role in the air absorption performance. In this kind of airflow process, in order to obtain good sound absorption effect, rock wool composite board can gradually achieve good noise reduction effect, and this effect is also widely used in building thermal insulation.
