利用ＰＶＣ和无机物等研制了一种性能优良的吸声材料。该吸声材料具有低频吸声系数好、成型加工简单、成本低等优点。着重讨论了岩棉含量、厚度、发泡时间和发泡温度等因素对吸声材料的吸声性能的影响。
The use of PVC and inorganic and other developed a good performance of the sound-absorbing material. The sound-absorbing material has a low-frequency sound absorption coefficient, forming simple, low cost. The effects of rock wool content, thickness, foaming time and foaming temperature on the sound absorption performance of sound-absorbing materials are mainly discussed.
