Back Pressure Setting Problem in PBT '2079851475616104452
Sorun Belirtisi
Too low back pressure causes poor plasticization of the material with unmelted particles, and too high back pressure generates shear heat degradation.
Neden Analizi
The back pressure is set improperly, and the back pressure is not set in coordination with the barrel temperature and screw speed.
Çözüm
Set the back pressure at 0.3-1.0MPa; optimize according to the plasticization quality and melt temperature.
Temel Çıkarım
PBT back pressure needs to balance plasticization and degradation risk.
