本文介绍的自润滑材料——填充F—4在2D压缩机上的应用,特别是在高压级中采用,经几年来运行实践的考验,取得了良好的效果。 填充F—4材料的基体为聚四氟乙烯(F—4),添加剂为玻璃纤维、青铜粉、石墨及二硫化钼。添加剂使F—4的载荷—速度性能大大提高。填充F—4与钢对摩时,在钢表面上会形成转移膜,使其由与金属的摩擦改变成为与其本身的摩擦,因此改善了磨损性能。F—4的磨擦系数低,静摩擦 This article describes the application of self-lubricating material - filling F-4 in the 2D compressor, especially in the high-pressure stage, after several years of operation of the test, and achieved good results. F-4 filled with PTFE matrix material (F-4), additives for the glass fiber, bronze powder, graphite and molybdenum disulfide. Additives make the F-4’s load-velocity performance greatly enhanced. When F-4 is filled with steel, a transfer film is formed on the surface of the steel, changing it from friction with metal to friction with itself, thereby improving the wear performance. F-4 low coefficient of friction, static friction
