高分子阻尼材料 meaning in English

polymer damping materials

Using the dynamic mechanical analyzer ( dma ) , pdms / pma ipn was investigated at temperature of 5 - 180 c . the initiator , the component ratio , the type of pdms and the filler effected the damping properties . the result showed that the damping ability varied with the parameter and there was an optimal value . the excellent damping material in the papers was ipn , where tan man was 0 . 735 , and the damping functional temperature ranged with tan 8 > 0 . 3 was 46 c . the micro - morphology and structure of pdms / pma ipn were characterized by two kinds of sem
高分子阻尼材料的有效阻尼功能区是在ipn材料的t _ g区间内，而研究常温条件下的阻尼性能更具有重要应用价值，运用动态热机械分析( dma )仪对ipn阻尼材料进行表征，在5 180内对其损耗因子( tan )进行研究，发现引发剂和交联剂的用量、聚硅氧烷的用量和分子量等参数对ipn阻尼性能的影响较大，存在一个合理配比值，当pma与粘度为3300pa ? s的pdms之比(质量比)为1 . 17 ： 1 、交联剂用量为1时， tan最大值为0 . 735 ，大于0 . 3的温域差达到46 。
