The acoustic board is a plate-like material with sound absorption and noise reduction functions, mainly used in the theater, concert hall, museum, exhibition hall, library, interrogation room, galleries, auction hall, gym, report hall, multi-function hall, hotel lobby, hospital, shopping mall, school, piano, conference room, studio, studio, KTV room, bar, industrial plant, computer room, home noise reduction, etc.
Here is the content list:
l Acoustic board classification by producing materials
l Material properties of polyester fiber acoustic boards
1 Wooden
The wooden acoustic board is based on the essential processing of acoustic principles, consisting of finishes, core materials, and acoustic board thin felts. Wooden acoustic board plate slotted wood acoustic board plate and hole wood acoustic board plate.
2 Mine cotton
The surface treatment form of the toner sound-absorbent plate is rich in form, and the plate has a strong decorative effect. The surface-treated rolling mineral wool plate, commonly known as "caterpillar", shades of surface, shape, and different pore diameters.
3 Fabric
The fabric acoustic board plate-core material is centrifugal glass wool. Centrifugal glass wool is an acoustic material whose long-term use in the world has proven to have excellent acoustic board properties.
4 Polyester fiber acoustic board plate
Polyester fiber sound absorbers are an ideal sound absorbing ornamental material. Its raw material is 100% polyester fiber, with sound absorption, environmental protection, flame retardant, insulation.
1. Fire prevention performance
The fire prevention performance of the audible places such as the auditorium, the dance hall, the auditorium, the multi-functional hall, the gym, etc. is crucial. The polyester fiber acoustic boards are inspected by fire prevention parameters through the national fire detection center. The results show that there is better fire prevention performance, which meets the national standard GB8624B1 requirements.
2. Sound absorption performance
The sound absorption characteristics of the polyester fiber sound-absorbent panel and other porous materials are similar, and the acoustic board coefficient increases with the frequency, the high-frequency sound-absorbent coefficient is large, and the cavity is retaining the cavity and the spatial sound-absorbent of the composed thereof can greatly improve the material. Sound absorbing performance. The noise reduction coefficient is approximately from about 0.8 to 1.10, and it is a high-efficiency sound absorbing body of a wide frequency band.
3. Physical mechanics performance
The polyester fiber acoustic board has an acoustic board heat insulation thermal insulation, and the material is uniform, elastic, tough, wear-resistant, anti-impact, tear resistance, not easy to scale, large board size (9 × 1220 × 2440 ㎜)
4. Show the effect
The polyester fiber acoustic board has a variety of colors, which can be made into various patterns. The surface shape has a plane, square (mosaic), wide strip, thin strip. The sheet can be bent into a curved shape. The indoor body shape can be made more flexible and rich. Even art draws through the computer on the polyester fiber acoustic board plate.
5. Environmental safety
Safety of polyester fiber acoustic boards in two aspects, one aspect of material excellent mechanical properties, lightweight, not damaged by some brittle materials such as perforated plasterboard and cement fiber plugging plate after impact. There is a danger of falling in blocks. On the other hand, the release of hazardous substances has been detected by relevant state departments, and its formaldehyde release standard is ≤1.5 ㎎ / 1, and the detection result is 0.05 ㎎. The national standard GB18580-2001E1 requirements are met, which is in line with direct requirements for indoor decoration.
6. According to the environmental level
The acoustic board is in the substrate installation. According to the release of formaldehyde according to the material of the substrate, there is a total of E0, E1, E2 level, wherein the E0 level is the highest level of environmentally friendly, E1 second, E2 formaldehyde release relatively speaking, the highest. Directly used in indoor installations, E1 levels are qualified.
