LDPE Air Ring Cooling
Fenómeno del problema
LDPE film transverse thickness deviation is large.
Análisis de la causa
Uneven air ring output makes bubble cooling inconsistent in all directions; 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.
Solución
Clean the air ring for uniform air; stabilize air temperature and pressure; automatic air ring thickness closed-loop; 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.
Conclusión clave
Transverse thickness is controlled by air ring uniformity; 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.
