CEF extrusion film winding wrinkling
문제 현상
After the CEF extruded film is wound, transverse wrinkles and longitudinal creases appear
원인 분석
The film tension is uneven and fluctuates ±20%; the film thickness is uneven, causing inconsistent stretching of each section; the shrinkage rate after cooling is anisotropic
해결 방법
1) Automatic tension control system to stabilize the winding tension; 2) Improve the film thickness uniformity to ±5%; 3) Adjust the guide roller parallelism <0.05mm/m; 4) Fully cool the film to <30°C before winding
핵심 요약
Film wrinkling is caused by tension fluctuations and uneven thickness; automatic tension control and homogenization are the key
