Fire performance.
The fireproof performance of sound-absorbing materials in theaters, dance halls, auditoriums, multi-function halls, gymnasiums and other public gathering places is very important. Polyester fiber sound-absorbing panels 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.
Sound absorption performance.
The sound absorption characteristics of ester fiber sound-absorbing panels are similar to those of other porous materials. The sound absorption coefficient increases with the increase of frequency. The high-frequency sound absorption coefficient is very large. The cavity on the back and the space sound-absorbing body formed by it can greatly improve the sound absorption of the material. performance. The noise reduction coefficient is about 0.8~1.10, making it a wide-band high-efficiency sound absorber.
Physical and mechanical properties.
Polyester fiber sound-absorbing board has the characteristics of sound absorption, heat insulation and heat preservation, and the material of the board is uniform and solid, flexible, tough, abrasion-resistant, impact-resistant, tear-resistant, not easy to be scratched, and large in width (9×1220×2440mm).
The display effect is good.
Polyester fiber sound-absorbing panels come in a variety of 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.
Environmental protection and safety.
The safety of polyester fiber sound-absorbing board is manifested in two aspects. On the one hand, the material has excellent mechanical properties, is light in 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 is the release of harmful substances. The formaldehyde emission standard requirement is ≤1.5㎎/1, and the test result is 0.05㎎/1. It meets the requirements of the national standard GB18580-2001E1 and meets the requirements for direct use in interior decoration. Requirements.
