摘　　要：对三种Ⅳ型高压储氢气瓶内胆材料尼龙6(PA6)的氢气和氦气渗透性进行了研究,主要分析了温度对渗透行为的影响以及两种气体渗透特性的差异。在15~55℃的测试温度范围内,氢气的透过系数高于氦气,两种气体的透过系数都随着温度的升高而增大,但通过对渗透活化能的对比,氦气对升温的依赖性更强。通过对比相同测试条件下两种气体的透过系数,得出了两种气体的转换系数的范围区间,为氦取代氢进行实验提供了数据支持。The permeation behavior of hydrogen and helium in the liner of a type IV high-pressure hydrogen storage vessel,specifically nylon 6(PA6),was studied.The effects of temperature on the permeation behavior and the differences between the two gases were analyzed.Within the test temperature range of 15-55℃,the permeation coefficient of hydrogen was higher than that of helium,and both increased with temperature.However,comparing the activation energy for permeation,it was found that helium had a stronger dependence on temperature increase.By comparing the permeation coefficients of the two gases under the same test conditions,the range of conversion coefficients for the two gases was obtained,providing data support for the replacement of hydrogen by helium.
