What is the role of basalt fiber silencing cotton in the application?

Basalt fiber silencing cotton has good thermal insulation, fire prevention, sound insulation, heat insulation and other performance characteristics, and is one of the commonly used thermal insulation and sound-absorbing materials in the construction industry. However, due to its intricate surface structure, it is often made into various sound-absorbing components for concealed use.

Good sound insulation materials, for example, our purpose is mainly sound insulation, so to put it bluntly, it is to "eliminate" the noise. For example, "gradient silencing cotton" is a kind of porous material with laminated stepped density, and the holes inside are connected, and the sound enters and rubs against the hole wall of the material, and the energy is converted to achieve the purpose of attenuating sound energy.

If the flow resistance is too small, it means that the basalt fiber sound-absorbing cotton is sparse, and 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, and 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.

On the basalt fiber silencing cotton, when some attachments are treated, it is also necessary to pay attention to its directionality, not because of its own reverse and its paint to achieve scratches or scratches, and after cleaning, must also be covered, often more often, like this basalt fiber silencing cotton is often because of too much attachment, and let the performance decline, so there are often many car owners are also cleaning in this regard, and when cleaning, we must pay attention to this aspect of the problem.
