Main Characteristics of Glass Cotton

2019/05/05

The sound absorption characteristics of centrifugal glass wool are not only related to thickness and bulk density, but also to cover data, structure and other factors. In the construction and use, it is necessary to take into account the cost, beauty, fire prevention, moisture-proof, dust, aging resistance and other issues.

Arbitrary cutting

Anti-bacterial and anti-mildew, anti-aging, anti-corrosion to ensure a healthy environment.

It can be cut and shaped at will.

Stability of physical properties

The national standard GB/T 13350-2000, which is certified by AS/NSZ4859.1 in Australia and New Zealand, is used for insulation, sound absorption and noise reduction in industrial buildings, warehouses, public facilities, exhibition centers, shopping malls, indoor playgrounds and sports venues.

Centrifugal glass wool belongs to porous sound absorption data and has good sound absorption function. The reason why centrifugal glass wool can absorb sound is not because of its rough appearance, but because there are many small holes and holes connected inside and outside. When the sound wave is incident on centrifugal glass wool, it can enter the data along the pore, causing the oscillation of air molecules in the air and ground. Because of the viscous resistance of air and the friction between air molecule and pore wall, sound energy is transformed into heat energy and is lost.
