Analyze the characteristics of rock wool board?

Stone wool board, also known as rock wool insulation decorative board, is an inorganic fiber board made mainly of basalt as the main raw material and processed by high-temperature melting. It was successfully tested in June 1981. Rock wool board is a new type of insulation, flame insulation, and sound absorption material.

Rock wool board is an artificial inorganic fiber processed by high-temperature melting, which has the characteristics of light weight, low thermal conductivity, heat absorption, and non flammability. Initially developed, it is a common application type in construction and is mainly used in industrial buildings. It should comply with the provisions of the "Application Types and Basic Requirements of Building Insulation Materials".

fireproof

Shida rock wool raw materials are made of natural volcanic rocks, which are non combustible building materials and fire-resistant materials.

Main fire protection characteristics:

⊙ It has the highest fire protection level of A1, which can effectively prevent the spread of fire.

⊙ The size is very stable and will not elongate, shrink, or deform in the event of a fire.

⊙ High temperature resistance, melting point above 1000 ℃.

⊙ No smoke or combustion droplets/fragments are generated during a fire.

⊙ Will not release harmful substances and gases in a fire.

Thermal insulation

Shida rock wool fiber is slender and flexible, with low slag ball content. Therefore, the thermal conductivity is low, and it has excellent insulation effect.

Sound absorption and noise reduction

Shida rock wool is an ideal sound insulation material, and a large number of slender fibers form a porous connection structure, which determines that Shida rock wool is an excellent sound absorption and noise reduction material.

Hydrophobicity

The hydrophobicity rate of Shida hydrophobic rock wool products can reach 89.9%; Extremely low water absorption and no capillary penetration.

Moisture resistance performance

Shida rock wool has a volumetric moisture absorption rate of less than 0.2% in environments with high relative humidity; According to the ASTMC1104 or ASTM1104M method, the mass moisture absorption rate is less than 0.3%.

Non corrosive

Shida rock wool has stable chemical properties, a pH value of 7-8, is neutral or weakly alkaline, and does not corrode metal materials such as carbon steel, stainless steel, and aluminum.

Safety and environmental protection

Shida rock wool has been tested to contain no harmful substances to the environment, such as asbestos, CFC, HFC, HCFC, etc. Will not be corroded or produce mold or bacteria. (Rock wool has been recognized by international cancer research authorities as a non carcinogenic substance)

Related performance

Fire prevention: The surface material and insulation material of the colored composite sandwich panel are non combustible materials, which can fully meet the requirements of fire prevention regulations.

Durability: Various studies have shown that, and it has been widely used for over 40 years abroad, colored steel plates treated with special coatings have a shelf life of 10-15 years. Afterwards, anti-corrosion coatings are sprayed every 10 years, and the lifespan of the plates can reach over 35 years.

Aesthetics: The clear lines of the profiled steel plate come in over ten different colors, which can meet the needs of any style of building and achieve satisfactory results.

High strength: Using high-strength steel plate as the substrate (tensile strength 5600KG/CM), combined with state-of-the-art design and rolling forming, it has excellent structural characteristics.

Thermal insulation: The commonly used insulation materials for this composite board include rock wool, glass fiber cotton, polyethylene, polyurethane, etc., with low thermal conductivity and good thermal insulation effect.
