介绍了PVC-U管道的破裂原因和粘接修复工艺.从粘接工艺不合理、环境温度变化、PVC-U管材运输、储存不当、管道受到过度挤压几个方面综合分析了PVC-U管道的破裂原因.选用玻璃纤维布和环氧树脂胶黏剂作为修复材料对PVC-U管道进行粘接修复,通过显色法明确了PVC-U管道粘接修复部位的情况、对粘接表面进行粗化打磨和有机溶剂清洗、准备玻璃纤维布和配制环氧树脂胶黏剂、涂胶固化完成了PVC-U管道的破裂粘接修复工艺过程.采用水压法对PVC-U管道破裂的粘接修复质量进行了检验,结果表明修复效果好.“,”The main reason of rupture and the bonding repair process of PVC-U tube were introduced.The reasons of the rupture of PVC-U tube were analyzed from the aspects of the unreasonable bonding process,the change of temperature,the improper transport and storage of PVC-U tube and the excessive squeezed.The glass-fiber and epoxy adhesive were selected to complete the bonding repair process of PVC-U tube.The bonding repair process included the defining status of bonding parts by the coloring method,the coarsen and cleaning by the organic solvent of the bonding surface,the preparation of glass-fiber and epoxy adhesive,gelatinizing and curing.The repairing quality was inspected by hydrostatic pressure method,the results showed that it had good effect.
