LLDPE casting roll temperature
Sorun Belirtisi
Poor roll contact of LLDPE cast stretch film
Neden Analizi
Chill roll temperature or air knife condition is poor; 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
Çözüm
Chill roll temperature 20-40°C; optimize air knife; clean roll surface; 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
Temel Çıkarım
Casting roll contact relies on roll temperature and air knife; 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
