rubber and plastic insulation boards

How is the sound insulation effect of rubber and plastic insulation boards? Today, we are going to introduce the sound insulation function of rubber and plastic insulation boards. Maybe many people will ask, can the insulation effect be achieved by wrapping rubber and plastic insulation boards? Let's take a look together! Firstly, the sound absorption performance of rubber and plastic insulation boards is closely related to the physical structure of the product itself. Due to the tightly foamed structure and elastic surface of rubber and plastic insulation boards, they have a good effect on reducing external sounds. However, in the actual use of rubber and plastic insulation boards, many environmental factors determine the sound insulation and noise reduction effect of rubber and plastic insulation boards. For example, their thickness and density, as well as the air flow resistance, have a significant impact on sound insulation and noise reduction. Air flow resistance is usually the ratio of the air pressure on both sides of the material per unit thickness to the air flow between the two sides. It also affects the sound absorption efficiency of rubber and plastic insulation boards. If the flow resistance is too small, it indicates that the structure of the entire material is very loose. Noise is particularly easy to pass through this material during the process of air vibration, thus resulting in a decrease in sound absorption and noise reduction performance. Let's take an example: for instance, rubber and plastic wave cotton or rubber and plastic egg cotton processed from rubber and plastic insulation boards. A friend asked us to wrap this product around the sewer, but the effect was not good. The wavy shape of high-quality rubber and plastic egg cotton is an important factor in determining the sound insulation effect of the product. The concave and convex shapes and dense open-cell bubbles refract sound waves to achieve the effect of reducing sound. If the wrapping method is chosen, the rubber and plastic insulation board manufacturer suggests using thickened rubber and plastic boards with adhesive on the back. Because to fully utilize the excellent noise reduction characteristics of rubber and plastic insulation boards, the thickness should be determined based on the actual situation. Therefore, we can conclude that when using rubber and plastic egg cotton for sound insulation, the rubber and plastic insulation board should be made into a concave and convex surface to face the sound source. Noise is harmful to people, and noise reduction is to isolate the sound source within the range that the human body can tolerate, and rubber and plastic insulation boards are important materials in the process of noise treatment. Another point is to increase the thickness of rubber and plastic insulation boards. As the thickness of rubber and plastic insulation boards gradually increases, the sound absorption coefficient of some medium and low frequencies will gradually increase, but the high-frequency sound absorption coefficient changes little. When the total weight of the entire rubber and plastic insulation board increases, their low and medium-frequency sound absorption coefficients will gradually increase. As the total weight increases to a certain extent, the structure of the rubber and plastic insulation board will become particularly dense, and the overall sound absorption efficiency will gradually improve. It can be seen that in the actual use effect of rubber and plastic insulation boards, the sound absorption coefficient and sound absorption performance of different sounds are directly related to them. If their bulk density is high, the sound absorption performance will decrease. Because the material becomes particularly dense, it will have a significant impact on their use effect. A quiet environment brings people a better living or living experience. Rubber and plastic insulation boards are the best choice for sound insulation and noise reduction in building materials!
