摘　　要：介绍自主研制的中国首套99 MPa氢渗透测试装置,解决氢气高压密封、微量氢渗透精准测量等关键技术难题,可实现工作压力0.1~99 MPa、温度-40~85℃下的非金属材料氢渗透测试,获得塑料内胆氢渗透系数。基于该装置,分别开展环境参数为(87.5 MPa,15℃),(80.5 MPa,55℃),(70 MPa,85℃)和(70 MPa,-40℃)下的材料氢渗透实验,验证该装置的可靠性。The hydrogen permeability of the materials under high pressure is an important parameter for the safety of the plastic liner hydrogen storage cylinder.This study introduces the first 99 MPa hydrogen permeability testing apparatus developed independently in China,which solves the key technical problems such as high-pressure hydrogen sealing and precise measurement of the trace amount of hydrogen.The hydrogen permeability test of non-metallic materials under the working pressure of 0.1 MPa-99 MPa and the temperature of-40℃-85℃can be conducted using the apparatus.Using the testing apparatus,the hydrogen penetration tests of the plastic liner materials under four different working conditions,including(87.5 MPa,15℃),(80.5 MPa,55℃),(70 MPa,85℃)and(70 MPa,-40℃),were carried out,and the reliability of the testing apparatus was verified.This work provides test methods and technical support for the hydrogen permeation test of plastic liner materials and the development of domestic plastic liner materials.
