POE extrusion film winding wrinkling
Sorun Belirtisi
POE extruded film shows transverse wrinkles and longitudinal creases after winding
Neden Analizi
Film tension uneven, fluctuating ±20%; film thickness uneven causing inconsistent stretching of each section; shrinkage anisotropy after cooling
Çözüm
1) Automatic tension control system to stabilize winding tension; 2) Improve film thickness uniformity to ±5%; 3) Adjust guide roller parallelism <0.05mm/m; 4) Film fully cooled to <30°C before winding
Temel Çıkarım
Film wrinkling is caused by tension fluctuation and uneven thickness; automatic tension control and uniformization are key
