PETG '2079851475616104452 screw speed too high, gasification
Sorun Belirtisi
Excessive screw speed causes melt shear overheating, bubbles and degradation.
Neden Analizi
Excessive screw speed produces a large amount of shear heat, exceeding the PETG thermal stability limit.
Çözüm
Reduce the screw speed to a reasonable range of 50-100rpm; use back pressure to discharge gas.
Temel Çıkarım
PETG screw speed should be as low as possible under the premise of ensuring plasticization.
