Severe EEA extruder screw wear
ظاهرة المشكلة
After 200h of EEA extrusion, screw and barrel wear reaches 0.5mm
تحليل الأسباب
Filler causes large wear on the screw; insufficient screw material hardness, not nitrided; processing temperature too high causing EEA to adhere to the screw and aggravate wear
الحل
1) Use nitrided screw or bimetallic screw SK-2 alloy; 2) Reduce processing temperature to reduce adhesive wear; 3) Treat filler with coupling agent to reduce friction; 4) Regularly check wear, replace in time when >0.3mm
الخلاصة الأساسية
Screw wear is caused by filler friction and adhesion; wear-resistant screw and temperature control are the key
