Heavy EMA processing smoke

Problem Phenomenon

During EMA processing, large amounts of volatile smoke escape from the vent

Cause Analysis

Low molecular volatiles in EMA evaporate at processing temperature; additive decomposition produces smoke; exhaust system insufficient

Solution

1) Lower processing temperature to reduce volatilization; 2) Increase exhaust system capacity; 3) Select low-volatile raw material grade

Key Takeaway

Heavy smoke is caused by volatile evaporation; lowering temperature and exhausting are key

EMA processing smoke volatiles exhaust system temperature reduction
