自六十年代末,美国联合碳化物公司发表了柔性石墨板材的研究专利后,接着美国洛克惠尔阀门工程研究设计中心试验所为解决原子能阀门泄漏问题,于1971年采集了16种不同类型的填料在64个试验点进行试验,其结果表明,柔性石墨密封效果居于首位。从此柔性石墨密封盛行于世。我国虽然起步较晚,但发展较快,上海材料研究所等单位于1978年开始研制以来,通过各方面的考核,已在石油化工、化肥、农药、仪表、制药、热电等工业部门中应
Since the late 1960s, United Carbide Corporation published a patent on flexible graphite sheet, followed by the Lockheed Valve Engineering Research and Design Center in the United States to solve the problem of atomic valve leakage test, in 1971 collected 16 different types of Fillers were tested at 64 test points and the results showed that flexible graphite sealing effect in the first place. Since then flexible graphite seal prevalent in the world. Although China started late, but developed rapidly, Shanghai Institute of Materials and other units began to develop in 1978, through all aspects of assessment, has been in the petrochemical, chemical fertilizers, pesticides, instruments, pharmaceuticals, thermoelectric and other industrial sectors should
