LLDPE film regrind usage
ظاهرة المشكلة
After blending in regrind, bubble stability and film surface quality decline.
تحليل الأسباب
Regrind melt index changes and may bring in impurities; LLDPE is more sensitive to the regrind proportion.; During on-site troubleshooting, verify item by item according to this mechanism, avoiding blindly adjusting the machine based only on experience.
الحل
①Control the regrind proportion; ②dry the regrind and remove impurities; ③monitor the blended melt index; ④limit regrind for key products.; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability.
الخلاصة الأساسية
LLDPE regrind management must be stricter than LDPE; melt index monitoring is a necessary control means.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence.
