碳—石墨材料良好的耐腐蚀性、独特的自润滑性和突出的导热导电性,在国民经济各部门得到了广泛地应用。当要用它作不透性材料使用时,必须改变石墨材料多孔易渗的缺点;当要在特别苛刻的环境中使用时,必须赋于材料更高的耐酸碱、耐高温、耐磨、耐冲击等性能;当要得到高整流性能电刷时,电刷材料必须具有超凡的电阻。 Carbon-graphite materials, good corrosion resistance, unique self-lubricating and outstanding thermal conductivity, in various sectors of the national economy has been widely used. When it is used as impermeable material, the porous material of porous graphite material must be changed. When it is to be used in a particularly harsh environment, it must be given higher resistance to acid, alkali, high temperature, abrasion, Impact resistance and other performance; when you want to get high commutation brush, brush material must have extraordinary resistance.
