Fenómeno do problema
LLDPE film thickness and strength fluctuate.
Análise das causas
Frost line height fluctuation changes the stretching and cooling state; During on-site troubleshooting, verify item by item according to this mechanism, avoiding blindly adjusting the machine based only on experience; This mechanism has been repeatedly verified by industry data and should be confirmed first during troubleshooting.
Solução
Air ring airflow and air temperature stable; frost line height fixed and monitored; 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.
Conclusão principal
Frost line stability is a sign of LLDPE film consistency; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a reference for troubleshooting similar problems in the future.
