Core Material:100% polyester fiber
Installation:Glue or nails
1.Sound absorption performance
The sound absorption properties of polyester fiber sound absorbing panels are similar as other porous materials, whose sound absorption coefficient increases with increasing frequency. High frequency sound absorption coefficient is very large,the cavity behind the back and the sound absorber formed by it can greatly improve the sound absorbing performance of the material.The noise reduction coefficient is approximately 0.8 to 1.10, it is regarded a high-efficiency sound absorber in a wide band.
2.Physical and mechanical properties
Polyester fiber sound absorbing panels have sound absorbing and heat insulation properties,and the material of the board is even and solid, elastic, tough, wear-resistant, impact-resistant, tear-resistant, not easily scratched, large plate width (9x1220x2440mm).
Polyester fiber sound absorption panels are available in more than 40 colors and can be combined into various patterns.Surface shape is available for flat, square (mosaic), wide strip, thin strip.The sheet can be bent into a curved shape.Can make the indoor design more flexible and full of effects. You can even copy art paintings on a polyester sound absorbing panel by computer.
The fireproof performance of sound absorbing materials is crucial in public places such as theaters, dance halls, auditoriums, multi-purpose halls, gymnasiums, etc.Polyester fiber acoustic panels have been tested by fire prevention parameters by the National Fire Protection Testing Center, the results show that it has good fire performance, which is in line with the national standard GB8624 B1 requirements.
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, there is no danger of falling or chipping like some brittle materials such as perforated gypsum board and cement fiber pressure board if being damaged by impact. On the other hand, the release of harmful substances. Tested by relevant state departments,the standard requirements for formaldehyde emission≤1.5mg/1,the test result is 0.05mg/1, which meets the national standard GB18580-
2001 E1 requirements, and meets the requirements for direct use in interior decoration.
Easy to remove dust and easy to maintain. Dust and impurities can be flicked by a vacuum cleaner and tweezer. Dirty areas can also be wiped with a towel and water and detergent.
Scope of application
The acoustic panel polyester board is used for opera house, theater, recording studio,broadcasting room, audition room, TV station, radio station, business office, multi-purpose hall, conference room, studio, concert hall, auditorium, gymnasium, leisure and entertainment city, hotel, KTV, high-end villas or places with strict acoustic requirements.
