随着科学技术的发展,各种高温、高压、高速、强腐蚀、强辐照的工作环境相续出现,机器设备处在越来越苛刻的工作条件下,物料漏泄所造成的浪费以及由此而带来的环境污染越来越严重。在这种形势下,密封的新结构、新材料、新工艺不断涌现,其中柔性石墨就是一种收效显著的新型密封材料,而且优于过去采用的任何一种密封形式。它是由天然鳞状石墨经过特殊化学处理、热处理加工而成的不含任何粘结剂的纯石墨制品,除了具有天然石墨原有的特性外,还具有广阔的使用温度范围、优良的耐腐蚀性和自润滑性能、优良的气密性、独特的柔韧性和回弹性、良好的导热导电性,是一种理想的高级密封材料,可广泛用于航空、航海、交通、炼油、化工、化纤、化肥、
With the development of science and technology, various high-temperature, high-pressure, high-speed, highly corrosive and strong irradiation work environments continue to emerge. The equipment is under increasingly harsh working conditions, the waste caused by material leakage and thus The environmental pollution brought about more and more serious. In this situation, the new structure of the seal, new materials, new processes continue to emerge, including flexible graphite is a significant new sealing material, and better than any of the sealing used in the past. It is made from natural flake graphite after special chemical treatment, heat treatment and processing of pure graphite products without any binder, in addition to the original features of natural graphite, but also has a wide temperature range, excellent corrosion resistance It is an ideal high-grade sealing material which can be widely used in aviation, navigation, traffic, oil refining, chemical industry, chemical fiber ,fertilizer,
