摘要
以低碱水泥和膨胀珍珠岩为主要原料 ,辅之以分散性良好的增强剂聚丙烯纤维 ,研制出一种新型吸声材料 .它具有成本低、耐久性高、吸声性能好的特点 .文中对引气剂用量、珍珠岩用量及水灰比对材料吸声性能影响进行了研究与分析 .结果表明 ,这些因素对材料吸声性能均有重要影响 .
A new type of sound absorbing materials mainly made from low alkaline cement and expanding pearlite has been investigated on the basis of sound absorption principle. Its good characteristics include low cost,high durability and good property of sound absorption. The paper analyzes its performance with the range of the content of gas former,expanding pearlite and water-cement ratio.The results show that the variables have great effects on the sound absorbing performance of the samples.
