O soluție acustică grozavă - panou acustic din fibră de poliester

The sound-absorbing body composed of polyester fiber acoustic panels not only has high sound absorption coefficient and wide sound absorption rate, that is, excellent acoustic performance, but also has good physical and mechanical properties and indoor performance.
Sound absorption performance.

The sound absorption properties of polyester fiber acoustic 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 spatial sound-absorbing body formed by it can greatly improve the material's performance. 
Sound absorption performance.

The noise reduction coefficient is approximately 0.8-1.10, which becomes a broadband high-efficiency sound absorber.

Physical and mechanical properties
Polyester fiber acoustic 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 size (9×1220×2420MM)

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.

safety
The safety of the polyester fiber acoustic 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 standard requirement of formaldehyde emission is ≤1.5?1, and the test result is 0.05/1.
