LDPE Winter Water Temperature
Problem Phenomenon
In winter, the frost line of the LDPE film production line fluctuates.
Cause Analysis
Cooling air temperature changes with the environment; in winter, too low air temperature makes the frost line unstable; During on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience; This mechanism has been repeatedly verified by industry literature and should be confirmed first during troubleshooting.
Solution
Adjust air temperature by season; workshop insulation; frost line height monitoring compensation; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability; Change only one variable at a time and record parameter changes to facilitate locating effective measures.
Key Takeaway
With seasonal changes, adjust air temperature to stabilize the frost line; After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence; Incorporate this case into the defect archive as a troubleshooting reference for similar future problems.
