Glass Fibre extruded film has transverse ripples
Fenómeno del problema
Glass Fibre extruded film surface transverse periodic ripples, wavelength 5-10mm
Análisis de la causa
Haul-off roller vibration or unstable speed produces periodic stretching change; cooling roller eccentric or surface not round causes periodic contact pressure change
Solución
1) Overhaul haul-off roller to eliminate vibration; 2) cooling roller rounded, eccentricity <0.02mm; 3) install pressure stabilizing device on extruder to eliminate pressure fluctuation; 4) haul-off speed stable control ±0.5%
Conclusión clave
Transverse ripples are caused by haul-off vibration and roller eccentricity; equipment overhaul and stable control are key
