Wood wool acoustic panels in aspen fiber as raw material, combined with a unique inorganic hydraulic cement binder, using the technique of continuous operation at high temperature and high pressure conditions is made. The product has only through the synthesis of a number of different materials in order to obtain physical properties. 1, unique appearance, good sound-absorbing surface of filamentous unique texture, giving a rough sense of the original, meet the modern idea of ??returning to nature. Surface can be spray color and printing finishes processing, spraying up to six times. To achieve the highest sound absorption 1.00. 2, the structure solid structure and firm, and elastic, impact resistance, can withstand when used in the stadium basketball, soccer and volleyball repeated impact without cracking or breakage. 3, simple installation and easy to cut, installation is simple, general woodworking tools can be. 4, anti-bacterial moisture 25mm plates at 85% humidity conditions can be used, including open and swimming pool, but except where direct contact with water. 5, energy-saving insulation, long life due mainly from wood processing, thermal conductivity as low as 0.07, with strong thermal insulation properties. Economic and durable, long life, according to customized sizes. 6, the combustion performance testing combustion performance GB8624B1 level. Formaldehyde emission and grade: 0.1 E1 grade. 7, product specifications Thickness (mm): 15mm or 25mm Size (mm): 600X1200, 600X2400, 603X2440, 1220X2440 or other specifications.
