LLDPE and LDPE blending
Fenómeno do problema
Old equipment processing pure LLDPE has reduced output, blending LDPE improves it but performance is discounted
Análise das causas
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
Solução
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
Conclusão principal
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
