PVC hose production line in the production process will inevitably have some failures, such as: the outer surface of the plastic hose pipe is rough and unsmooth, to adjust the process temperature in time; The wall thickness of the pipe is uneven, adjust the wall thickness on the mold; There are grooves on the inner surface of the pipe, check whether the inner pipe has entered the water and reduce the internal temperature of the mold; The outer surface of the plastic pipe produced by the PVC hose production line has grooves, and the water outlet pressure of the sizing sleeve is adjusted, and the water output is required to be balanced.
If a jitter ring appears inside the pipeline, adjust the sizing sleeve to make the water outlet uniform; No vacuum, check whether the water inlet of the vacuum pump is blocked; The cutting gauge length is inaccurate, check whether the gauge wheel is pressed, etc., must be found, viewed and processed in time.
In the production process of PVC hose production line, common problems of plastic pipes: First, the impact resistance is poor, even 10 impacts, all ruptured. Second, the tensile strength and toughness are poor, often manifested as brittle, low elongation and easy to break. Third, the softening temperature is low, which is easy to deform when heated, which reduces the impact resistance, tensile strength and toughness of the pipe.
