柔性石墨密封垫片的研究现状及发展趋势
Present Research and Development Trend of Flexible Graphite Sealing Gasket
摘要
Abstract
The present research of flexible graphite sealing gasket were summarized .The preparation and performance of flexi -ble graphite,the main structure of metal-graphite composite gasket were introduced .The preparation technology mainly includes chemical oxidation method 、electrochemical method、microwave、detonation and gaseous volatilization method .The structures in-clude metal-graphite spiral wound gasket ,flexible graphite corrugated metal gasket and metal to metal contact type gasket .The re-search status of graphite sealing mechanism were also analyzed and the main leaking models were summarized .The application of graphite seal in areas such as nuclear power and development trend were also prospected .The future development direction of graphite gasket concentrates on highly purified graphite and design of new structure .The finite element analysis as auxiliary meth-ods will become one of research hot spot .关键词
