中文摘要:
      通过自组的基于气相色谱-质谱联用仪的气密性测试系统,分析三元乙丙橡胶(EPDM)、丁腈橡胶(NBR)和氟橡胶(FKM)对新型绝缘气体全氟异丁腈(C4F7N)和其平衡气体CO2的气密性。结果表明:FKM对C4F7N和CO2均具有较高的惰性和稳定性以及具有致密的微观结构、较小的比表面积,其气密性显著优于EPDM和NBR,更适合作为密封材料用于使用C4F7N和CO2作为绝缘气体的设备。
英文摘要:
      By a self-assembled air tightness test system based on gas chromatography-mass spectrometry,the air tightness of ethylene propylene diene rubber(EPDM),nitrile rubber(NBR)and fluororubber(FKM) to the new insulating gas perfluoroisobutyronitrile(C4F7N) and its equilibrium gas carbon dioxide(CO2) were tested respectively.The results showed that,FKM had high inertia and stability to C4F7N and CO2,dense microstructure and small specific surface area,its air tightness was significantly better than EPDM and NBR,and it was more suitable as sealing material for equipment using C4F7N and CO2 as insulating gas.
