New price for spot supply of 40kg glass wool roll boardCentrifugal glass wool has fluffy and interlaced fibers inside, with a large number of tiny pores, making it a typical porous sound-absorbing material with good sound absorption properties. Centrifugal glass wool can be used to make wall panels, ceilings, spatial absorbers, etc., which can absorb a large amount of sound energy in the room, reduce reverberation time, and minimize indoor noise.

The sound absorption characteristics of centrifugal glass wool are not only related to thickness and bulk density, but also to factors such as cover material and structural construction. In architectural applications, it is also necessary to simultaneously consider various issues such as cost, aesthetics, fire prevention, moisture resistance, dust, and aging resistance.

Centrifugal glass wool belongs to porous sound-absorbing materials and has good sound absorption performance. The reason why centrifugal glass wool can absorb sound is not due to its rough surface, but because it has a large number of tiny pores and voids that are connected internally and externally. When sound waves are incident on centrifugal glass wool, they can enter the interior of the material through the pores, causing vibrations of air molecules in the pores. Due to the viscous resistance of air and the friction between air molecules and pore walls, sound energy is converted into heat energy and lost.

Centrifugal glass wool has good sound absorption performance for high frequencies in sound. The main factors affecting the sound absorption performance of centrifugal glass wool are thickness, density, and air flow resistance. Density is the weight per cubic meter of material. Air flow resistance is the ratio of air pressure and air velocity on both sides of a material per unit thickness. Air flow resistance affects the sound absorption performance of centrifugal glass woolzuiImportant factors. If the flow resistance is too small, it indicates that the material is sparse, and air vibration is easy to pass through, resulting in a decrease in sound absorption performance; If the flow resistance is too high, it indicates that the material is dense, making it difficult for air vibrations to be transmitted, and the sound absorption performance also decreases. For centrifugal glass wool, there is flow resistance in its sound absorption performance. In practical engineering, it is difficult to measure air flow resistance, but it can be roughly estimated and controlled through thickness and bulk density
