通过电机用氢化丁腈橡胶O形密封圈、丁腈橡胶O形密封圈,环氧树脂包覆电极在氟利昂F113环境下的高温加速老化试验,对材料的使用寿命进行预测。结果表明,氢化丁腈橡胶O形密封圈在工况下使用寿命为37.5年,能满足装置密封使用10年的要求。

It was predicted the life of above mentioned materials such as theNBR O seal ring、the HNBR O seal ring and the electrode coated with epoxy resin through the high temperature and accelerated aging test in the Freon F113. According to the experimental results, the HNBR O seal ring could meet the seal requirement after ten years, it’s aging life expectancy was 37.5 years under operating conditions.
