0.1-0.5mm black speck carbonized matter appears inside EEA products
Análise das causas
EEA carbonized by prolonged heating in barrel dead zones; carbon deposits on the screw head; raw material impurities
Solução
1) Lower processing temperature to reduce carbonization; 2) Regularly clean the screw and barrel; 3) Filter raw material to remove impurities
Conclusão principal
Black specks are caused by thermal carbonization and carbon deposits; lowering temperature and regular cleaning are key
