Carbonized Black Specks Inside EVOH
Sorun Belirtisi
0.1-0.5mm carbonized black specks appear inside EVOH products
Neden Analizi
EVOH carbonized from prolonged heating in barrel dead zones; carbon deposit at screw head; raw material impurities
Çözüm
1) Reduce processing temperature to decrease carbonization; 2) Regularly clean screw and barrel; 3) Filter raw material to remove impurities
Temel Çıkarım
Black specks are caused by thermal carbonization and carbon deposit; cooling and regular cleaning are key
