EEA extruded film has transverse ripples
문제 현상
Transverse periodic ripples on the EEA extruded film surface, wavelength 5-10mm
원인 분석
Haul-off roller vibration or unstable speed producing periodic stretching change; cooling roller eccentric or out-of-round surface causing periodic contact pressure change
해결 방법
1) Overhaul the haul-off roller to eliminate vibration; 2) Round the cooling roller, eccentricity <0.02mm; 3) Install a pressure stabilizing device on the extruder to eliminate pressure fluctuation; 4) Stable control of haul-off speed ±0.5%
핵심 요약
Transverse ripples are caused by haul-off vibration and roller eccentricity; equipment overhaul and stable control are the key
