LLDPE and LDPE blending
Problembeschreibung
Old equipment processing pure LLDPE has reduced output, blending LDPE improves it but performance is discounted
Ursachenanalyse
When processing LLDPE on low-power old equipment, high viscosity limits output; blending more than 15-20% LLDPE into LDPE also reduces output; 50% blend is an economical transitional solution
Lösung
①Use LDPE/LLDPE blend as transition on old equipment; ②50% blend concentration is the balance point between equipment and performance; ③the long-term solution is equipment upgrade; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Wichtigste Erkenntnis
Blending LDPE with LLDPE is the balancing art between equipment and performance; 50% concentration is the classic transitional formula; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
