CEF internal black speck carbonization
Problem Phenomenon
Black specks of 0.1-0.5mm carbides appear inside the CEF product
Cause Analysis
CEF is carbonized by long-term heating in the dead corner area of the barrel; carbon deposits at the screw head; raw material impurities
Solution
1) Reduce the processing temperature to reduce carbonization; 2) Regularly clean the screw and barrel; 3) Filter the raw material to remove impurities
Key Takeaway
Black specks are caused by thermal carbonization and carbon deposits; reducing temperature and regular cleaning are the key
