Glass wool is the molten glass fibrosis formation of shaped material, cotton, chemical composition of glass, is a kind of inorganic fiber with good forming, small volume density, thermal conductivity Di, insulation, good sound absorbing performance, corrosion resistance, chemical properties and stability.
Sound absorbing cotton internal fiber fluffy staggered, the existence of a large number of tiny pores, is a typical porous sound absorbing materials, has good sound absorption properties. Sound absorbing cotton can be made into a wall, ceiling, space absorber, can absorb a large amount of sound within the room, reduce the reverberation time, reduce indoor noise.
Absorbent cotton absorption characteristics not only with the thickness and density, and the covering material, structure and other factors. In building application still needs while taking into consideration the cost, appearance, fire, moisture, dust, aging etc.
Sound absorbing cotton with fire prevention, heat insulation, easy to cut and other excellent properties, is one of the most commonly used materials building absorption.
Architectural acoustics in commonly used sound-absorbing glass wool has a thickness of2.5cm,5cm,10cm, bulk density of 16,24,32,48,80,96,112kg/m3. Usually use 5cm thick,12-48kg/m3sound absorption cotton.
