产品特点：
Product features:
指试样的初始厚度与在规定时间、规定温度下压缩后，经过规定恢复时间的试样zui终厚度差异。差异的大小与初始厚度有关。
The initial thickness and in the specified time, the prescribed temperature compressed specimen, specimen thickness difference after the prescribed final recovery time. The size difference is related to the initial thickness.
主要用途：
Main uses:
用夹具及定位块将海绵压陷至原始厚度的50%、75%、90%，放置在规定温度的恒温箱内，待至22小时、72小时之后从中取出压缩器，将试样从压缩器中取出放置30min后，测量厚度，计算其变形量。
