LDPE Film Static Electricity Dust Attraction
Problembeschreibung
The film surface attracts dust and requires repeated cleaning before printing and laminating.
Ursachenanalyse
Film friction generates static electricity that attracts environmental dust; static accumulation is more serious when ambient humidity is low.; During on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience.
Lösung
①Install ionized air static elimination devices; ②Increase ambient humidity; ③Add antistatic masterbatch; ④Standardize the cleaning process.; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability.
Wichtigste Erkenntnis
Static management relies on both equipment and material means; antistatic masterbatch suits long-term storage scenarios.; After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
