几种泡沫塑料的受热影像行为分析

Analysis image of Several foam deformation behaviors in the process of heat

采用SJY影像式烧结点试验仪研究几种常见泡沫塑料受热过程中的变形行为,并记录不同温度下聚苯乙烯(模塑与挤塑)、聚氨酯和两种酚醛树脂泡沫塑料的受热变形情况。根据变形图像绘制温度-变形曲线,为分析泡沫塑料的受热变化过程提供参考。

Several foam deformation behaviors in the process of heat are studied by the application of SJY modelling material fireproof performance cryoscope,with different temperature recorded. The temperature deformation curve is mapped according to the deformation images. It gives useful reference to the results of analysis of the heat changes in the process of foam.
