LLDPE color masterbatch dispersion
Fenómeno del problema
Poor dispersion of color specks in LLDPE film
Análisis de la causa
The melt index of the color masterbatch carrier does not match the LLDPE; when troubleshooting on site, verify item by item according to this mechanism to avoid blindly adjusting the machine based only on experience; this mechanism has been repeatedly verified by industry data and should be confirmed first during troubleshooting
Solución
Select color masterbatch with matching melt index; mix material uniformly; verify dispersion effect; 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
Select color masterbatch by melt index matching; 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
