PE pipe: has moderate rigidity, strength, and good flexibility, creep resistance, environmental stress cracking resistance and hot melt performance.
PVC pipe: has the characteristics of acid and alkali resistance, wear resistance, good electrical insulation, low softening temperature, limited to use below 80℃.
PP pipe: odorless, tasteless, non-toxic, good heat resistance, good chemical stability and so on.
▏Common faults and troubleshooting
Plastic pipe production line common faults include:
Rough surface: Adjust the process temperature, reduce the cooling water temperature, check whether the waterway is blocked.
Internal jitter ring: Adjust the water discharge of the sizing sleeve to ensure that the water discharge is uniform, and check whether the vacuum gasket is too tight.
No vacuum: Check whether the inlet of the vacuum pump is blocked and whether the vacuum pump works normally.
Uneven wall thickness of the pipe: adjust the wall thickness of the mold, adjust the Angle of the vacuum setting machine and the nozzle in the spray box.
▏Care and maintenance
1. Regular inspection: Regular inspection of various components on the production line, including extruder, head, styling cooling system, tractor and cutting device, etc., to ensure that they are in good condition.
2. Cleaning and lubrication: regularly clean the dust and stains on the production line, and lubricate the parts that need to be lubricated to reduce wear and failure.
3. Replace the worn parts: for the parts with serious wear, such as screw, head mold, etc., it should be replaced in time to avoid affecting the production quality and efficiency.
4. Adjust the process parameters: according to the actual production situation, timely adjust the process parameters, such as temperature, pressure, speed, etc., to ensure product quality and production efficiency.
▏Training and operation
1. Staff training: Regular training of production line operators to improve their operational skills and safety awareness and reduce the impact of human factors on production.
2. Standard operation: Formulate and strictly implement the operation procedures of the production line to ensure that the operators operate in accordance with the procedures to avoid misoperation and illegal operation.
