固体润滑板,系由玻璃纤维织物浸以环氧酚醛树脂为基体的石墨胶液,通过加温加压,经交联固化复合而成。由固体润滑板做成的摩擦件与摩擦轨道形成一对(对偶件一般为金属)摩擦体。在摩擦初始阶段,处于干摩擦运动,逐渐转变为由微粒状石墨层为润滑剂的摩擦运动,进而达到了自润滑的效果。摩擦一段时间后,由于石墨粒子不再从固体润滑板上脱离,固体摩擦件达到工作稳定的阶段,摩擦体的运动阻力大大减少,摩擦系数降低,同时也降低了摩擦件在运
Solid lubricating board, which is made of glass fiber fabric impregnated with epoxy phenolic resin as matrix graphite glue, is heated and pressurized, and is formed by cross-linking curing compound. The friction member made of the solid lubricating plate forms a pair of friction members (the pair is generally a metal) friction body with the friction rail. In the initial stage of friction, it is in a dry friction movement and gradually changes into the frictional movement of the lubricant by the granular graphite layer, thereby achieving the self-lubricating effect. After a period of friction, since the graphite particles are no longer detached from the solid lubricating plate, the solid friction material reaches the stage of stable operation, the frictional resistance of the friction material is greatly reduced, the friction coefficient is reduced, and the friction material is also reduced
