Jing Li Lun long fiber acoustic panels are installed belong to simple acoustic materials, long fiber acoustic panels Installation is simple and quick. Its sound-absorbing decorative effect is superior, is a very good novel sound-absorbing decorative materials. 1. Long fiber acoustic panels with sound insulation, mute, noise, fire-retardant insulation, insulation and so on, even a solid material, not only flexibility, toughness, abrasion resistance, impact resistance, easy to cut, with a cavity formed resonance absorber plate is very effective, is a high bandwidth efficient sound-absorbing material. Also long-fiber insulation decorative plate light, excellent material properties, unlike some brittle materials such as perforated gypsum board and cement fiber boards and other pressure generating chips or chunks at risk of falling, formaldehyde emission standard 0.05 / 1, is far far less than the state of formaldehyde emission standards of less than or equal to 1.5. is to replace the conventional foam or fiberglass laminate add new acoustic material, and easy to destroy not pollute the environment, it can be recycled. 2. Long fiberboard insulation principle: Further reading: 3. Long fiber acoustic panels are inside the material has an internal communication with a large number of tiny pores, these pores can drill down acoustic material, and the material friction effect sound energy into heat. Metallic porous sound-absorbing material, sound absorption characteristics with the increasing frequency of sound absorption coefficient increases, which means that no high-frequency absorption good low frequency absorption. A necessary condition for absorption of porous materials is: there is a lot of material voids, gaps in communication between each other, internal porosity-depth material. One misconception is that the rough surface of a material having absorption properties, it is not true, such as stucco, stone surface of the punch was basically does not have the sound absorption capability. The second misconception is that the holes inside the material with a large number of materials, such as polystyrene, polyethylene, closed-cell polyurethane, etc., with good acoustic performance, in fact, these materials due to internal pores no connectivity, Sonic does not get to vibration friction inside the material, and therefore the absorption coefficient is small. 4. The absorption mechanism of long fiber with hollow cavity structure composed of a thin absorption resonance absorption. The resonance frequency due to severe vibration plate absorbs sound energy. For the high and low frequency have good absorption properties.
