Application of by938 and by939 to repair the rubber lining of manhole door of mixed bed
-
DeviceName:
Manhole door of mixed bed
-
DeviceProblem:
The extrusion between the rubber lining on the inner wall of the manhole door and the manhole cover plate will cause cracks in the original rubber lining after long-term operation, and the medium will penetrate into the rubber lining, resulting in bulging, which needs to be repaired. (the original repair adopts the phosphorus coating process, resulting in deformation after extrusion)
