Rear zone temperature deviating from the recommended value affects plasticization
문제 현상
Rear zone temperature deviating from the recommended value affects plasticization
원인 분석
Rear zone temperature too high, material softens too early
Rear zone temperature too low, material not fully preheated
Temperature difference between rear zone and middle zone too large, plasticization discontinuous
Temperature control deviation causes actual rear zone temperature fluctuation
Rear zone temperature setting does not consider the melting characteristics of cellulose acetate butyrate
해결 방법
Set the rear zone temperature near the lower limit of 170-230°C according to the gradient
Ensure the rear zone temperature is 10-15°C lower than the middle zone
Stabilize the rear zone temperature control deviation ≤3°C
Adjust the rear zone temperature according to cellulose acetate butyrate characteristics
Check the working condition of heating bands and thermocouples
핵심 요약
Rear zone temperature needs to be set according to the gradient to ensure continuous plasticization
