硬质聚氨酯泡沫两种表观密度测量方法之比较分析

Comparative Analysis of Two Methods for Determination of Apparent Density in RPUF

对硬质聚氨酯泡沫两种表观密度测试方法作了比较分析,指出两者基本一致。浮力法简单、快速。

Two methods for determination of the apparent density in rigid polyurethane foam are compared and analyzed in this paper. It is demonstrated that the floating power method is simple and convenient for companies and factories which produce or use rigid polyurethane foam.
