Heavy Smoke in EVOH Processing
Problembeschreibung
During EVOH processing, smoke and large amounts of volatiles escape from the vent
Ursachenanalyse
Low molecular volatiles in EVOH evaporate at processing temperature; additive decomposition produces smoke; exhaust system insufficient
Lösung
1) Reduce processing temperature to decrease volatilization; 2) Increase exhaust system capacity; 3) Select low-volatile raw material grade
Wichtigste Erkenntnis
Heavy smoke is caused by volatile evaporation; cooling and exhaust are key
