杭州The difference between rock wool composite board and glass wool composite board

Rock wool composite board and glass wool composite board have excellent insulation performance and thermal conductivity, long service life, and wide applicability. What is the difference between these two rock wool materials?

Rock wool composite board has thermal insulation performance, which is a basic feature of rock wool composite board products. The shelf life of special color boards after coating is 10-15 years, and the service life of road boards can exceed 35 years. External wall rock wool composite board ships and buildings have certain requirements for water and fire, reducing insulation and sound absorption oil, electrical and chemical equipment noise. Magnesium exterior wall insulation rock wool composite board, glass magnesium fireproof partition wall, cement rock wool insulation board surface, using special materials and 5-8mm reinforced board refractory fibers and grids on the surface, can cut the middle position rock wool insulation board, aluminum foil fireproof glass cloth is enclosed, and then special adhesives and metal fasteners are used to make the appearance of the rock wool glass magnesium refractory board, Foam type such as convenient construction and heat insulation has reached the construction method of similar panels, and the cost is low and moderate. it is a kind of fire and heat insulation material for exterior walls that is worth promoting. The fireproof price of rock wool composite board: The surface material of the colored stone composite intermediate layer is non combustible material, and its insulation material can fully meet the requirements of fire regulations. At room temperature (approximately 25 ℃), its thermal conductivity typically ranges from 0.03 to 0.047w/(Mok). The combustion performance and combustion performance of rock wool composite panels depend on the amount of combustible adhesive. Rock wool composite board itself is an inorganic silicate fiber that is not flammable. Organic adhesives or additives are sometimes added during product processing, which can have a certain impact on the combustion performance of the product.

The rock wool composite board has good sound insulation and absorption performance, and the products of the sound absorption mechanism have a porous structure. When sound waves pass through, the friction caused by flow resistance causes the fiber absorber to become a part of the sound and prevent the propagation of sound waves. It is widely used in industries such as shipbuilding, metallurgy, power construction, etc. The installation and construction of this product are convenient, energy-saving, and cost-effective.

Glass wool composite board has high optical density, high thermal conductivity, large absorption coefficient, and good flame retardancy. It can be widely used for heating, air conditioning, constant temperature cold and hot water pipelines, cold storage insulation and sound insulation, etc.

Compared with rock wool composite board, glass wool composite board has the advantages of low bulk density, low pill content, low thermal conductivity, long service life, and high fiber toughness. However, the maximum temperature of rock wool composite board is about 600 ℃, while the maximum temperature of wool composite board is only 260 ℃.

From the above comparison, it can be said that rock wool composite board is a better choice in terms of fire prevention and insulation, but in terms of weight and thermal conductivity, glass wool composite board is a better choice. Therefore, when choosing, it should be based on your own actual situation, and the most important thing is to analyze and select specific situations.
