Polyester fiber sound-absorbing board is a kind of noise-reducing material with sound-absorbing function made of polyester fiber as raw material by hot pressing. Can create a quiet working and living space. The construction is simple, and various shapes can be changed through woodworking tools. Polyester fiber sound-absorbing panels can meet the requirements of different sound-absorbing and noise-absorbing effects, and are widely used in domestic sound-proof materials and acoustic engineering fields, and are deeply trusted and selected by acoustic designers from all walks of life.
Sound absorption performance
The sound-absorbing characteristics of polyester fiber sound-absorbing panels are similar to other porous materials. The sound-absorbing coefficient increases with the increase of frequency. The sound-absorbing coefficient of high-frequency is very large. The noise reduction coefficient is roughly around 0.8 to 1.10, making it a high-efficiency sound-absorbing body with a wide frequency band.
Physical and mechanical properties
Polyester fiber sound-absorbing board has the characteristics of sound-absorbing, heat-insulating and heat-insulating, and the material of the board is uniform and firm, full of elasticity, toughness, wear resistance, impact resistance, tear resistance, not easy to be scratched, and the board width is large (9×1220×2420㎜).
fire performance
The polyester fiber sound-absorbing panel has been tested by the National Fire Protection Testing Center for fire protection parameters, and the results show that it has good fire performance and meets the requirements of the national standard GB8624B1.
safety
The safety of polyester fiber sound-absorbing panels is manifested in two aspects. On the one hand, the material has excellent mechanical properties, light weight, and will not produce fragments or fragments after impact damage like some brittle materials such as perforated gypsum boards and cement fiber pressurized boards. There is a danger of falling. On the other hand, it is the release of harmful substances. After testing by relevant state departments, the standard requirement for formaldehyde release is ≤1.5㎎/1, and the test result is 0.05㎎/1. It meets the requirements of the national standard GB18580-2001E1, and is suitable for direct use in personnel work areas.
Ease of cleaning
Easy to remove dust and easy 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.
