Juku fiber sound-absorbing decorative art board

1. The material has excellent acoustic performance, and it is light in weight. After being damaged by impact, it will not be like some fragile materials (such as perforated gypsum board and cement fiber pressure board) to produce fragments or there is a danger of falling.
2. Tested by relevant state departments, the formaldehyde emission is 0.05MG/1, which meets the requirements of the national standard GBI8580-2001E1 and meets the requirements of direct use in interior decoration.
Fire performance: the fire performance of all kinds of decoration materials in public gathering places is very important. The test of the fire protection parameters by the National Fire Protection Testing Center shows that the fire protection performance of the poly-cool fiber sound-absorbing board meets the national standard (GB862481).
Scope of application: indoor interior walls and pendants of public buildings such as exhibition halls, concert halls, conference centers, lecture halls, film and television halls, schools, computer rooms, libraries, etc., in order to improve the sound quality and voice clarity.
Sound absorption performance: The sound absorption performance of poly-cool fiber sound-absorbing decorative art board is similar to other porous sound-absorbing materials, and the sound absorption coefficient increases with the increase of frequency. The sound absorption coefficient of high frequency is very large, and the back cavity and the space sound absorber made of it can greatly improve the sound absorption performance of the material. The noise reduction coefficient is about 0.8~1.10, making it an efficient sound absorber with wide frequency band.
