| 摘 要： | 抗冲击聚苯乙烯(PS-1)悬臂梁缺口冲击强度测试是与制样、环境状态调节、铣缺口、测试环节等多个要素相关的条件实验,这些实验条件直接影响了冲击强度的再现性.由于仪器等条件限制,目前国内各生产厂家执行的制样及检测标准不完全一致,导致分析结果可比性差.本文注重讨论如何提高 PS-1悬臂梁冲击强度测试结果的再现性问题,使不同生产企业的抗冲击聚苯乙烯(PS-1)的悬臂梁冲击强度结果有较好的可比性.

| Abstract: | The test of Izod notched impact strength of PS-1 relates to sample preparation,environmental state regulation,milling notch,test course and so on.These test conditions influence the reproducibility of impact strength test results.Because of the restriction of instruments,sampling and test standard adopted by national laboratories is inconsistent,which results in poor comparability of analysis results.In this paper,how to improve the reproducibility of Izod impact strength test results of PS-1 was discussed,which can result in preferable comparability of analysis results of Izod impact strength of PS-1 in different production enterprises. |
