EVA extruded film has transverse corrugations
문제 현상
EVA extruded film surface has transverse periodic corrugations with wavelength 5-10mm
원인 분석
Traction roller vibration or unstable rotation speed producing periodic stretching changes; cooling roller eccentricity or out-of-round surface causing periodic contact pressure changes
해결 방법
1) Overhaul the traction roller to eliminate vibration; 2) Round the cooling roller with eccentricity <0.02mm; 3) Install a pressure stabilizing device on the extruder to eliminate pressure fluctuations; 4) Stable control of traction speed ±0.5%
핵심 요약
Transverse corrugations are caused by traction vibration and roller eccentricity; equipment overhaul and stable control are key
