Performance Characteristics Of Soundproof Rockwool Fire Insulation Board
Posted by: Date:23.Aug.2022
Soundproof Rockwool Fire Insulation Board is made of natural rock, ore and other raw materials, melted in a cupola or other pool kiln (temperature below 2000 ℃), blown with a pressure of 50 atmospheres, and quenched into fibers. Or use the spinning method to drop the molten liquid flow on the multi-stage rotary rotor, and throw it into fibers by centrifugal force. The diameter is generally 3-9 microns, the bulk density is 50-200 kg/m^3, and the thermal conductivity at room temperature is 0.029-0.046 Watt/m²Kelvin, below 600℃, it is 0.111～0.145W/m²Kelvin, non-combustible, mildew, and moth-free. According to the temperature of use, it is divided into ordinary rock wool; high temperature rock wool. Rock wool resistance. For single crystal furnace, metallurgical casting, petroleum cracking and space technology ablation-resistant, high-temperature thermal insulation materials; sound-absorbing materials and thermal insulation materials for buildings and equipment; and natural asbestos substitutes for cement products, rubber reinforcing materials and high temperature Sealing material, high temperature filter material and high temperature catalyst carrier, etc.
Performance characteristics of rock wool board
1. Thermal insulation performance: Good thermal insulation performance is the basic characteristic of rock wool and slag wool products. The thermal conductivity of rock wool is usually between 0.03 and 0.047W/(moK) at room temperature (about 25°C).
2. Combustion performance: The combustion performance of rock wool and slag wool products depends on the amount of flammable adhesives in them. Rock wool and slag wool are inorganic mineral fibers and are not combustible. In the process of processing into products, organic binders or additives are sometimes added, which will have a certain impact on the combustion performance of products.
3. Sound insulation performance: Rock wool board has excellent sound insulation and sound absorption performance. Its sound absorption mechanism is that this product has a porous structure. When sound waves pass through, friction is generated due to the effect of flow resistance, so that part of the sound energy is fiber. Absorbed, Yin hinders the transmission of sound waves.
Application of rock wool board: Rock wool board is widely used in construction and industrial equipment, pipelines, kilns for thermal insulation, fire protection, sound absorption, earthquake resistance, metallurgy, machinery, building materials, petroleum, chemical and other industries. Thermal insulation material for the effect of rock wool thermal insulation products.
