摘要
实验研究了环境温度变化对聚乙烯发泡材料动态缓冲性能的影响,在参考相关温度试验标准及实际包装件流通环境温度统计分析的基础上,分别进行了常温、40℃和60℃等3种温度条件下聚乙烯发泡材料的动态冲击试验。研究结果表明,环境温度上升使聚乙烯发泡材料的动态载荷能力下降,冲击加速度升高,缓冲保护性能下降。
Dynamic compression tests of EPE samples were carried out at ambient temperature, 40 C and 60 re- ferring to temperature test standard and statistics of package temperature during practical circulation. The results indi- cated that when the temperature increases from ambient temperature to 40 C and 60 C, the dynamic loading ability of EPE decreases, the impact acceleration increases, and the cushioning protection performance degrades.
