摘要
对全氟醚橡胶密封圈低温条件下密封泄漏问题进行了理论分析,从改善材料压缩永久变形性能方面出发,调整二段硫化工艺参数,并进行产品低温密封试验。试验表明,调整后的二段硫化条件在保证全氟醚橡胶本身物理机械性能的条件下,提高了全氟醚橡胶密封圈在低温条件下的密封性能。
Leakage of perfluoroether rubber O seals under cryogenic condition was analysed theoretically. Parameters of the second vulcanizing process were adjusted and the cryogenic sealing tests were conducted for the purpose of compression performance improvement. The results show that the cryogenic sealing properties of the perfluoroether rubber seals were improved effectively without changing of the physical and mechnical properties.
