Tell You Why You Should Use Basalt Fiber?

The emergence of basalt fiber silencing cotton has brought us great convenience and help, and has been loved by a wide range of people, so what are its application places? The mid-to-high frequency of the sound has good sound absorption performance.

The main factors affecting the performance of basalt fiber silencing cotton are thickness, density and air flow resistance. Air flow resistance is the ratio of air pressure and air velocity on both sides of a material per unit thickness. Air flow resistance is an important factor affecting the sound absorption performance of basalt fiber silencing cotton.

If the flow resistance is too small, the material is sparse, the air vibration is easy to pass through, and the sound absorption performance is reduced, and if the flow resistance is too large, the material is dense, the air vibration is difficult to enter, and the sound absorption performance is also reduced. For basalt fiber sound-absorbing cotton, there is flow resistance in sound absorption.

Basalt fiber silencing cotton has countless small three micropores, large porosity, when the sound wave invades the glass fiber cotton, the energy will be inhaled in large quantities due to friction with the fiber and different sizes of air pockets. Generally speaking, the sound absorption rate is as high as 90% or more, which is a good talent to prevent noise interference, which is higher than the average requirements of NRC.
