Sound absorption principle of rock wool sandwich board

Sometimes the rock wool sandwich board needs to participate in organic binder or additives, which will have a certain impact on the incineration function of products. Sound insulation function: rock wool and slag wool products have excellent sound insulation and absorption functions. The sound absorption mechanism is that this product has porous structure. When sound waves pass through, part of the sound energy is absorbed by fibers due to the conflict of the effect of flow resistance, which hinders the transmission of sound waves.

Precautions for use of rock wool sandwich board

First of all, when using rock wool sandwich board, we must pay attention to prevent rain. It is very important not to work in rainy days. In addition, we should consider whether it is used for cold insulation or thermal insulation. If it is cold insulation, we must add moisture-proof layer, so as to achieve good results. If it is thermal insulation, we must pay attention to the question of moisture-proof. After all, we must pay attention to anti-corrosion when recycling rock wool board. Although the material itself can play a good anti-corrosion effect, it does not mean that we don't need to pay attention. If we don't pay attention, the material can be corroded.
