用自然堆积法测定膨胀梗丝的填充值

Determination of Expanded Cut Stem Filling Value by Natural Stacking Method

摘要: 对DD密度计法和自然堆积法两种测试膨胀梗丝填充值的方法进行了实验分析对比。采用DD密度计测定法的不足之处是只注重了梗丝的耐压弹性,而忽略了梗丝的柔软性,不能准确反映梗丝的实际膨胀效果;而用自然堆积测定法则能较为准确地反映梗丝的实际膨胀效果,是一种简便可行的方法。

Abstract: The relation between DD density meter method and natural stacking method for determining filling value of cut stem was discussed.The results showed that the filling value of expanded cut stem could be accurately determined by natural stacking method, and the method is simple and convenient.
