Polyester fiber acoustic decorative panels with sound-absorbing, mute, noise, fire-retardant, insulation, thermal insulation and other effects, material uniformly solid, not only flexibility, toughness, abrasion resistance, impact resistance, easy to cut, formed with a cavity Sheet resonance absorber is very effective, is an efficient wideband sound-absorbing material. Furthermore polyester fiber acoustic decorative plate light, excellent material properties, unlike some brittle materials such as perforated plasterboard and cement fiber board and other produce pressurized dangerous debris or debris falling, formaldehyde emission standards 0.05㎎ / 1 far less than the state is less than or equal to 1.5 formaldehyde emission standards is to replace the conventional foam or fiberglass laminates add new acoustic materials, and easy to destroy not pollute the environment, can be recycled polyester fiber acoustic principle: Yes There are a large number of small interior materials communicating pores, these pores in depth along the acoustic inner material, the action of friction with the material of the acoustic energy into heat. The case of porous sound-absorbing material, sound absorption characteristics with the higher frequency absorption coefficient increases, which means there is no low-frequency absorption of high-frequency absorption is good. A necessary condition for sound absorption is a porous material: the material has a lot of voids, gaps in communication between each other, internal porosity-depth material. One misconception is considered a material having a surface roughness of sound absorption properties, it is not true, for example, stucco, stone surface punch was basically do not have the sound absorption capability. The second misconception is considered a material having a large number of holes inside material, such as polystyrene, polyethylene, closed-cell polyurethane, etc., with good acoustic performance, in fact, these materials do not have connectivity due to internal holes, sonic depth not Internal friction material vibration, and therefore the absorption coefficient is small and polyester fiber sound absorption and sound absorption mechanism of the body cavity structure is composed of thin resonant sound absorption. The resonance frequency, due to severe vibration plate absorbs sound energy. The pair have good high-frequency sound absorption performance. Applications: Polyester fiber acoustic decorative panels can be used for home theater, hotels, dance halls, nightclubs, KTV box, concert halls, function rooms, studios, recording studios, theaters, offices, meeting rooms, an indoor gymnasium, a library, exhibition hall, classrooms, training centers, interrogation rooms ... and other indoor places. Miramar has a sound-absorbing acoustic panels, mute, noise, fire-retardant, insulation, thermal insulation and so on. Specifications: 1220 * 2420 * 9mm has more than forty kinds of colors Miramar polyester fiber acoustic panels: solid material uniformity, not only flexible, toughness, abrasion resistance, impact resistance, easy to cut, thin it with a cavity resonance absorption constituted sound body is very effective, is an efficient wideband sound-absorbing material.
