EMA internal black specks carbonization
문제 현상
0.1-0.5mm black specks of carbonized material appear inside EMA products
원인 분석
EMA carbonized by prolonged heating in barrel dead zones; carbon deposit at screw head; raw material impurities
해결 방법
1) Lower processing temperature to reduce carbonization; 2) Regularly clean screw and barrel; 3) Filter raw material to remove impurities
핵심 요약
Black specks are caused by thermal carbonization and carbon deposit; lowering temperature and regular cleaning are key
