Glass Fibre internal black specks carbonization
Problem Phenomenon
Glass Fibre product interior shows 0.1-0.5mm black specks carbides
Cause Analysis
Glass Fibre heated for long time in barrel dead corner zone and carbonized; screw head carbon deposit; raw material impurities
Solution
1) Reduce processing temperature to reduce carbonization; 2) regularly clean screw and barrel; 3) filter raw material to remove impurities
Key Takeaway
Black specks are caused by thermal carbonization and carbon deposit; cooling and regular cleaning are key
