LLDPE film production line speed-up
Sorun Belirtisi
After speed-up, bubble instability and thickness deviation problems erupt collectively.
Neden Analizi
LLDPE high-speed production has higher requirements for cooling and bubble stabilization; the original equipment capability reaches its limit.; During on-site troubleshooting, verify item by item according to this mechanism, avoiding blindly adjusting the machine based only on experience.
Çözüm
①Evaluate cooling system upgrade; ②adopt a dual-lip air ring; ③strengthen online thickness measurement; ④stepwise speed-up verification.; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability.
Temel Çıkarım
Speed-up is a system engineering; cooling and inspection capabilities must precede the speed increase.; 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.
