柔性石墨又叫膨胀石墨,它是近几年研制使用的新型密封材料。 把天然石墨中的杂质除去,再以某种液体浸入石墨层间,用强制手段使其层间间隔扩大,就成了质地柔软的柔性石墨。它具有质地柔软,富有弹性,耐腐,既耐低温(-200℃)又耐高温(500℃),低摩擦系数,自润滑等一系列优良性能,因而成为很有前途的密封材料。 Flexible graphite, also known as expanded graphite, is a new type of sealing material developed and used in recent years. To remove impurities in natural graphite, and then some kind of liquid immersed in the graphite layer, with mandatory means to expand the interval between the layers, it becomes soft and flexible texture of graphite. It has a soft, flexible, decay resistant, both low temperature (-200 ℃) and high temperature (500 ℃), low coefficient of friction, self lubrication and a series of excellent performance, which has become a promising sealing material.
