Experimental Study on Hydrogen-exposed Rubber Materials for Hydrogen Transmission and Distribution Equipment
摘要
Abstract
This paper investigates the domestic and in-ternational standards for hydrogen-exposed rubber ma-terials,and proposes testing methods for hydrogen-exposed rubber materials used in hydrogen transmission and distribution equipment.Physical and mechanical property tests and gas resis-tance tests were conducted on three typical hydrogen-exposed rubber materials:fluoroelastomer(FKM),hy-drogenated nitrile butadiene rubber(HNBR),and ni-trile butadiene rubber(NBR).The results show that FKM exhibits the lowest tensile strength and elonga-tion at break among the three materials,while HNBR and NBR demonstrate superior physical and mechani-cal properties.FKM exhibits the lowest rebound resil-ience,indicating superior physical and mechanical properties.Hydrogen aging tests show no cracking in any of the three materials,confirming their applicabil-ity in hydrogen-exposed environments.The average minimum brittle temperature of FKM is-20 ℃,that of HNBR is-36 ℃,and that of NBR is-33 ℃.When the operating temperature of hydrogen-exposed equip-ment exceeds-20℃,all three materials are viable op-tions.For equipment operating within the temperature range of-33℃ to-20℃,either NBR or HNBR is suit-able.When the operating temperature falls between-36℃ and-33℃,HNBR is the recommended choice.In n-hexane immersion and high-pressure hydrogen im-mersion tests,FKM exhibits the smallest average vol-ume and mass change rates,indicating superior gas re-sistance compared to HNBR and NBR.Considering the physical and mechanical properties as well as the gas resistance performance,FKM should be prioritized for hydrogen transmission and distribution equipment.关键词
