Improper Screw Rotation Speed in PCTG '2079851475616104452
ظاهرة المشكلة
Too high a screw rotation speed causes excessive shear heat and degradation, and too low a speed causes insufficient plasticization.
تحليل الأسباب
The screw rotation speed is not optimized according to the characteristics of PCTG, and general parameter settings are not suitable.
الحل
Set the screw rotation speed to 50-80rpm; monitor the melt temperature to prevent overheating.
الخلاصة الأساسية
The PCTG screw rotation speed needs to balance plasticization and shear heat.
