Rubber insulation board to absorb the performance and itself has a direct relationship

Release time：2019-10-25

Rubber insulation board has good absorption performance for sound, and there are many factors that can influence sound in the actual use of rubber insulation board, such as their thickness and density and air flow resistance, which have great influence on them. Air flow resistance is usually the ratio of air pressure on both sides of the unit thickness material to the flow rate between the air on both sides, it will also affect the efficiency of the rubber insulation board to absorb sound. If the flow resistance is too small, it indicates that the whole material is very sparse. In the process of air vibration, it is particularly easy to pass through such a material, and their performance will be reduced.

In fact, with the gradual increase of the thickness of the rubber-plastic insulation board, the sound absorption coefficient of some medium and low frequencies will also gradually increase. However, the change of their high-frequency sound absorption coefficient is not particularly large. Under the condition of constant thickness, when the weight of the whole rubber-plastic insulation board increases, the sound absorption coefficient of their medium and low frequencies will gradually increase, but when the whole weight increases to a certain degree, the materials will become very tight, and their flow resistance will gradually be greater than the good flow resistance, and even the efficiency of absorbing sound will gradually decrease.

It can be seen that in the actual function of rubber-plastic insulation board, the absorption coefficient of different sounds, or the absorption performance, will have a direct relationship with themselves, and also have a direct relationship with the tolerance. If their bulk density is relatively high, then the performance of absorbing sound will decline, because the material becomes particularly close, so it will have a great impact on them.
