Large EAA processing smoke
Problem Phenomenon
Large amount of smoke and volatiles overflowing from the vent during EAA processing
Cause Analysis
Low molecular volatiles in EAA evaporate at processing temperature; additive decomposition produces smoke; insufficient exhaust system
Solution
1) Reduce processing temperature to reduce volatilization; 2) Increase exhaust system exhaust volume; 3) Select low-volatility raw material grade
Key Takeaway
Large smoke is caused by volatile evaporation; lowering temperature and exhausting is key
