Polymer metal powder, various additives formulated reaction, and then rolling and made, is to control noise in sound attenuation measures in the pipeline a new type of insulation material. The use of polymer-based metal powder composite acoustic vibration damping materials environmentally friendly fire-retardant insulation blankets; 1) acoustic insulation blankets lightweight materials; 2) Ultra-thin (1.2mm), good barrier properties (single 22.7 dB, equivalent to 128 times lower listening loudness! barrier effect of the sound is better than 1 m thick glass wool); 3) flame retardant, high strength, soft; 4) within the material loss, can effectively change the material of the "match effect ", improve insulation performance; 5) to facilitate the construction (dry construction); 6) low cost, to the maximum to meet the needs of consumers; 7) Versatile; 8) using the new surface treatment technology and composite technology; 9) This project is made of a polymer material and the acoustic result of joint efforts of the two disciplines; sonic vibrations will strengthen the bending waves, a phenomenon known as consistent effect. Then flexural vibration particularly large degree of convergence to the other side of the acoustic energy radiated in the air is particularly large, thereby reducing the sound insulation effect.
