Polyester fiber sound-absorbing panels have the functions of sound absorption, muteness, noise reduction, flame retardant, etc. The material is uniform and solid, not only elastic, tough, wear-resistant, impact-resistant, and not easy to The thin plate resonance sound absorber formed by scratching it and the cavity has an excellent effect. It is a high-efficiency sound-absorbing material with a wide frequency band. In addition, the polyester fiber sound-absorbing decorative board is lightweight and has excellent performance. Unlike some brittle materials such as perforated gypsum board and cement fiber pressurized board, there is a risk of falling fragments or fragments. The emission standard of formaldehyde.㎎/ is also far less than the national standard. The standard stipulates that the formaldehyde emission amount is less than or equal to. It is a new acoustic material that replaces the previous laminates plus sponge or glass fiber. It is easy to destroy, does not pollute the environment and can be recycled.

-:Kaicai-HeiTi:.. The sound absorption principle of polyester fiber board is that there are a large number of tiny connected pores inside the material. Along these pores, sound waves can penetrate deep into the material and cause friction with the material. The action converts sound energy into heat energy. The sound absorption characteristics of porous sound-absorbing materials are that the sound absorption coefficient gradually increases as the frequency increases, which means that low-frequency absorption is not as good as high-frequency absorption. The necessary condition for the sound absorption of porous materials is that the material has a large number of interconnected pores and the pores penetrate deeply into the material. One of the misunderstandings is that materials with rough surfaces have sound-absorbing properties. In fact, this is not the case, such as rough cement and stone with convex and concave surfaces. They basically have no sound-absorbing properties. The second misunderstanding is that materials with a large number of holes inside the material, such as polystyrene, polyethylene, closed-cell polyurethane, etc., have good sound absorption properties. In fact, these materials have no connectivity within the holes and sound waves cannot penetrate deep into the material to vibrate and rub. The sound absorption coefficient is very small and the sound absorption mechanism of the sound absorber structure composed of polyester fiber board and cavity body is thin plate resonance sound absorption. At the resonant frequency, a large amount of sound energy is absorbed due to the violent vibration of the thin plate. It has good sound absorption performance for medium, high and low frequencies.
