Longitudinal thickness fluctuation of PET film
문제 현상
The longitudinal thickness of PET biaxially stretched film fluctuates periodically, affecting winding flatness.
원인 분석
The extruder or metering pump output pulsates; casting drum speed fluctuates; stretching roller speed ratio is unstable; filter clogging causes pressure fluctuation.
해결 방법
Check the condition of the extruder and metering pump; stabilize the casting drum and stretching roller drives; replace clogged screens; use online thickness measurement feedback control.
핵심 요약
Longitudinal thickness fluctuation of PET film originates from equipment stability.
