The sound-absorbing properties of polyester fiber board are similar to those of other porous materials. The sound-absorbing coefficient increases with the increase of frequency. The high-frequency sound-absorbing coefficient is very large. The cavity on the back and the spatial sound-absorbing body formed by it can greatly improve the material's performance. Sound absorption performance. The noise reduction coefficient is about 0.8-1.10, which becomes a high-efficiency sound absorber with a wide frequency band.
2.Physical and mechanical properties
Polyester fiber board has the characteristics of sound absorption, heat insulation and heat preservation, and the material of the board is uniform and solid, flexible, tough, wear-resistant, impact-resistant, tear-resistant, not easy to be scratched, and large (9×1220×2440mm).
3.Variety of products
polyester fiber board come in more than 40 colors and can be assembled into various patterns. The surface shapes are flat, square (mosaic), wide strips, and thin strips. The plate can be bent into a curved shape. It can make the indoor figure design more flexible and changeable and effective. It is even possible to copy art paintings on a polyester fiber sound-absorbing panel through a computer.
4.Fire performance
polyester fiber board have been tested by the National Fire Protection Testing Center on fire parameters, and the results show that they have good fire resistance and meet the requirements of the national standard GB8624B1.
5.safety
The safety of the Polyester fiber board is manifested in two aspects. On the one hand, the material has excellent mechanical properties, light weight, and will not be broken or broken like some brittle materials such as perforated gypsum board and cement fiber pressurized board after being damaged by impact. The block is in danger of falling. On the other hand, it is the release of harmful substances. The formaldehyde emission standard requirement is ≤1.5㎎/1 and the test result is 0.05㎎/1 after testing by the relevant national departments. It meets the national standard GB18580-2001E1 level requirements and meets the requirements for direct use in personnel working areas.
6.Easy to clean
Easy to remove dust and simple to maintain. Dust and impurities can be flicked with a vacuum cleaner and a duster. Dirty parts can also be wiped with a towel, water and detergent.
