摘要
研究PVDF中空纤维膜拉伸性能的测试方法,通过单变量择优法分析不同拉伸标距、拉伸速率、浸泡温度、浸泡时间等因素对膜拉伸强度和拉断伸长率的影响并找到变化趋势,同时通过各组实验的变异系数确定PVDF膜在做拉伸试验时的最佳实验条件.
The study on the test method of tensile properties of PVDF hollow fiber membrane was carried out. The effects of different gauge, different tensile rate, different soaking temperature and different soaking time on the tensile strength of the membranes were investigated, the better experimental conditions from tensile strength experiments were determined by the coefficient of variation.
