柔性石墨密封材料是一种纯石墨制品,没有任何粘着剂或粘结材料,它具有耐腐蚀、耐高温,耐低温、耐高剂量辐照、导热、导电、摩擦系数低、自润滑等特点。且具有特殊柔性,是国际上七十年代新颖的工程材料。本文着重介绍制造这种材料的关键原材料—膨胀石墨粒子的制造方法。
Flexible graphite sealing material is a kind of pure graphite product without any adhesive or bonding material. It has the characteristics of corrosion resistance, high temperature resistance, low temperature resistance, high dose radiation resistance, thermal conductivity, electrical conductivity, low friction coefficient and self-lubrication. And has a special flexibility, is the international seventies novel engineering materials. This article focuses on the manufacture of expanded graphite particles, the key raw material for making this material.
