Sound absorption performance

The sound absorption characteristics of polyester fiber sound absorbing panels and other porous materials are similar. The sound absorption coefficient increases with the increase of frequency, and the high frequency sound absorption coefficient is large. The cavity behind the back cavity and the space absorbing body formed by it can greatly improve the material. Sound absorption performance. The noise reduction coefficient is approximately 0.8 to 1.10, which is a high-efficiency sound absorbing body in a wide frequency band.

Physical and mechanical properties

Polyester fiber sound absorbing panels have sound-absorbing and heat-insulating properties, and the material of the board is even and solid, elastic, tough, wear-resistant, impact-resistant, tear-resistant, not easily scratched, and large in width (9×1220×2440mm)

Product variety

Polyester fiber sound absorbing panels are available in more than 40 colors and can be assembled into a variety of patterns. The surface shape has a flat surface, a square (mosaic shape), a wide strip, and a thin strip. The sheet can be bent into a curved shape. It can make the indoor body design more flexible and effective. It is even possible to copy art on a polyester sound absorbing panel by computer.

Fire performance

The polyester fiber sound absorbing panel has been tested by the National Fire Protection Center for fireproof parameters. The results show that it has good fire performance and meets the national standard GB8624B1.

Safety

The safety of polyester fiber sound absorbing panels is manifested in two aspects. On the one hand, the excellent mechanical properties of the material, light weight and impact damage will not cause fragments or crushing like some brittle materials such as perforated gypsum board and cement fiber pressure board. There is a danger of falling of the block. On the other hand, the release of harmful substances, the standard of formaldehyde emission is ≤1.5mg/1, and the test result is 0.05mg/1. Meet the national standard GB18580-2001E1 requirements, in line with the area directly used for personnel.

Clean and simple

Dust removal is easy and maintenance is simple. Dust and impurities, use a vacuum cleaner and tweezers to flick. Dirty areas can also be wiped with a towel and water and detergent.
