Ⅰ. Surface of transparent PVC tube without shine

1. The mouth mold temperature is too low; the temperature of the transparent PVC tube mouth mold must be suitably raised.

2. Clean the mouth of the transparent PVC tube mold frequently if the inner wall of the mouth mold is not dry.

3. If the net compressed air supply is insufficient or there is air leakage, increase the transparent PVC tube air supply or inspect for and correct air leakage.

Ⅱ. The wall thickness of the clear PVC pipe is not uniform

1. The core mould and the mouth mould are not properly positioned; the core mould and the center of the mouth mould should be adjusted.

2. Check the transparent large clear pvc pipe traction device for uneven plasticization.

3. Because traction is abnormal, the transparent PVC tube air supply system should be smooth.

4. Insufficient compressed air, improve control of the transparent PVC tube plasticizing system.

5. If the temperature around the head is not stable, ensure that the transparent PVC tube head heating equipment is in good working order.

Ⅲ. Black markings on the surface of transparent PVC tubes

1. The additives in the raw materials are not equally disseminated; improve the mix and strengthen the mixing to increase dispersion performance.

2. The raw material fluidity is too low; enhance the transparent PVC tube raw material formula.

3. The temperature of the transparent clear pvc pipe head section and the filter is too high; it is necessary to lower the temperature.

4. Check the transparent PVC tube strainer, clear pvc coupler and diversion plate, as well as the head strainer and diversion plate and other substandard structures.

5. The filter network is dirty; the transparent PVC tube filter network should be cleaned regularly.

Ⅳ. Wrinkles and ripples on the surface of transparent PVC tubes

1. If the temperature of the transparent PVC tube mouth mold is too high or the heating is uneven, check whether the heating device is damaged and lower the temperature.

2. The water supply to the clear PVC pipe cooling and shaping equipment is insufficient, the water temperature is excessive, and it is necessary to increase the amount of water supply.

3. If the transparent PVC tube traction speed is too slow, increase it.

4. If the mouth mold made of the material isn't uniform, adjust the space between the clear PVC pipe mouth mold and the transparent PVC tube mouth mold.

Ⅴ. Cracks in the walls of transparent PVC tubes

1. Impurities in raw materials necessitate raw material processing.

2. If the core mould temperature is too low, raise the temperature of the transparent PVC tube core mould.

3. If the temperature of the transparent PVC tube barrel is too low, raise the temperature.

4. If the traction speed is too high, reduce the traction speed.

5. Adjust the transparent PVC tube recipe if there is too much lubrication.
