EVOH Processing Temperature Fluctuation
문제 현상
During EVOH processing, temperature fluctuates ±5-8°C, exceeding ±2°C control precision
원인 분석
PID parameters of temperature control system improper; heater bands aged with uneven power; thermocouple position improper, measurement deviation
해결 방법
1) Re-tune PID parameters; 2) Replace aged heater bands; 3) Adjust thermocouple position to the melt pool center
핵심 요약
Temperature fluctuation is caused by improper temperature control system; PID tuning and heater band replacement are key
