介绍一种用环氧树脂修复制动缸的方法。将一定成份的环氧树脂压入模内,压模的外壁是要修复的制动缸,而内壁是心子。在混合浆固化和热处理之后,便得到不需任何辅助加工的镜面。混合浆的成份列入组份混合浆中各组份的数量(按重量计) (?)—5环氧树脂 100 添加剂: 氧化亚铁《红粉》 38 B号一级陶瓷用细滑石粉 9 液体的聚硫橡胶(增塑剂) 18 结晶已二胺或聚乙烯多胺(硬化剂) 15 在称量以前,除了硬化剂以外,所有组份在温度110±10℃条件下烘干两个小时。称量是在精确度达0.5％的工业天平上进行的。混合浆按以下次序准备:将树脂注入容器,添加增塑剂,并搅拌均匀。然后加予先混合好的添加剂。硬化剂的添加量视压模的填充量而定。混合浆和模子零件的温度,在浇注以前为25—30℃。
A method of repairing brake cylinder with epoxy resin is introduced. A certain amount of epoxy resin into the mold, the outer wall of the die is to repair the brake cylinder, and the inner wall is the heart. After the mixture is solidified and heat treated, the mirror is obtained without any additional machining. (By weight) (-) - 5 Epoxy resin 100 Additive: Ferrous oxide “Red” 38 Fine grade talc powder for Class B ceramics 9 Liquid Polysulfide rubber (plasticizer) 18 Crystalline diamine or polyethylene polyamine (hardener) 15 All components except the hardener were dried at a temperature of 110 ± 10 ° C for two hours prior to weighing . Weighing is carried out on an industrial scale with an accuracy of 0.5%. The mixed paste is prepared in the following order: the resin is injected into the container, the plasticizer is added and the mixture is stirred well. Then add to the first mixed good additives. The amount of hardener added depends on the filling amount of the stamper. The temperature of the mix and mold parts is 25-30 ° C prior to pouring.
