Internal Black Specks and Carbonization of CMC
Problem Phenomenon
Black specks and carbonized matter of 0.1-0.5mm appear inside CMC products
Cause Analysis
CMC is heated for a long time in the dead corner area of the barrel and carbonizes; carbon deposits on the screw head; raw material impurities
Solution
1)Reduce processing temperature to reduce carbonization; 2)Regularly clean the screw and barrel; 3)Filter raw material to remove impurities
Key Takeaway
Black specks are caused by thermal carbonization and carbon deposits; temperature reduction and regular cleaning are the key
