塑料具有良好的防腐能力,在机械性能上还具有良好的耐磨性和较低的磨擦系数,因此近年来在机床检修上已经试用这种材料。铁道部长辛店机车车辆工厂自1964年7月开始试用热喷望塑料方法,用于调整车床尾座中心高度,并在20余台车床大溜板和各种镶条上进行了喷塗试验,经过将近一年的验证,情况良好,目前已在机床检修中正式采用这种 Plastic has good corrosion resistance, mechanical properties also have good wear resistance and low coefficient of friction, so in recent years in the machine overhaul have tried this material. The railway minister Xindian locomotive and rolling stock factory has been testing the heat-spray plastic method since July 1964 to adjust the center height of the lathe tailstock and carry out the spraying test on more than 20 lathe large slide plates and various inserts, After nearly a year of verification, in good condition, has been officially adopted in the machine maintenance of this
