PVC hose production line in the production process will inevitably have some failures, such as: the outer surface of the plastic 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.
You can also understand that the plastic pipes produced by the PVC hose production line may have poor impact resistance, poor tensile strength and toughness, often manifested as brittle, low elongation and easy to break. In addition, the softening temperature is low, easy to deform when heated, and reduce the impact resistance, tensile strength and toughness of the pipe.
