尽管在过去几十年已推出了许多弹性体流变性能的测试设备和新方法,但是一些传统方法还一直在使用。传统方法中,我们比较熟悉的是压缩永久变形,橡胶试样被两个金属板压缩,在一定时间内进行热老化,最后去除应力在预定时间测试试样高度。尽管此方法已被标准化,但是由于它需要较长 Although many test equipment and new methods for rheological properties of elastomers have been introduced in the past few decades, some traditional methods have been used. The traditional method, we are more familiar with the compression set, the rubber sample is compressed by two metal plates, heat aging in a certain period of time, and finally remove the stress at a predetermined time to test the sample height. Although this method has been standardized, it needs to be longer
