Sound Absorbing Panel

Rock wool sound-absorbing panel is what we usually call sound-absorbing and hydrophobic rock wool panel. It is a mineral fiber product. Rock wool sound-absorbing panel is made of natural rock as raw material, which is melted at high temperature, added with a small amount of binder, spun into fiber by high-speed centrifugation and processed. It is a special board that can be waterproof, sound-absorbing and noise reduction after collection, pendulum and solidification.

Sound Absorbing Panel

Rock wool panel, also known as rock wool insulation decorative board, takes basalt as the main raw material. Rock wool sandwich panel is an artificial inorganic fiber processed by melting. It has the characteristics of light weight, low thermal conductivity, heat absorption and non combustion. Rock wool is an ideal sound insulation material. A large number of slender fibers form a porous connection structure, which determines that rock wool is an excellent noise reduction and sound absorption material.

Rock Wool Sound Absorbing Panel

Performance of rock wool sound-absorbing board

Rock wool is an inorganic thermal insulation material. It is made of iron slag as the main raw material, which is melted and cooled by high-pressure steam injection. It has the advantages of light weight, low thermal conductivity, good elasticity, non combustion, non decay, and chemical stability. It also has excellent sound insulation performance.

  • Thermal insulation. Good thermal insulation is the basic characteristic of rock wool. Under normal temperature (about 25 ℃), their thermal conductivity is usually between 0.03~0.047w/ (Mok).
  • Combustion performance. The combustion performance of rock wool depends on the amount of combustible adhesive. Rock wool is an inorganic silicate fiber, which is nonflammable. 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.
  • Sound insulation performance. Rock wool has excellent sound insulation and absorption performance. Its sound absorption mechanism is that this product has a porous structure. When sound waves pass through, friction occurs due to the effect of flow resistance, so that part of the sound energy is absorbed by the fiber, which hinders the transmission of sound waves.

Characteristics of sound absorption panel

1. Superior sound absorption effect can effectively control and adjust the reverberation time of thespace and reduce noise.

2. The inner panel is firmly bonded with a non-woven fabric backing.3.Aperture: 3-6mm.

4. Opening rate: 78%.

5. The core material is made of glass wool and rock wool for heat insulation and excellent fire pre-vention effect.
