聚乙烯管材拉伸性能试验影响因素的分析

Analysis of influencing factors of tensile performance test of polyethylene pipe

分析了影响热塑性聚乙烯塑料管材拉伸试验结果的因素,包含试验环境温度、拉伸试验速度2个因素。通过对不同试验速度和不同试验环境温度的拉伸试验进行了分析。结果表明,试验速度、试验环境温度等因素均对拉伸性能产生较大影响。由此得出结论,测试严格按照标准条件进行,尽量减少人员和环境改变因素而影响试验结果。通过多组试验和数据分析,给出了试验环境温度、拉伸试验速度这2个因素对试验结果的影响程度,并通过分析得出了聚乙烯管材拉伸性能的标准试验速度和标准环境温度。

In this work,we analyzed the factors affecting the tensile experimental results of thermoplastic polyethylene pipes,which included the ambient temperature and tensile test speed.The results indicated that the tensile performance of the pipes was greatly influenced by the test speed and the test ambient temperature.The test was conducted in strict accordance with the standard conditions to minimize personnel and environmental change factors that affect the test results.Through multigroup test and data analysis,the influence of test temperature and standard test temperature of the PP pipe are presented.
