Large smoke in PVA processing
Problembeschreibung
During PVA processing, large amount of smoke and volatiles overflow from the vent
Ursachenanalyse
Low molecular volatiles in PVA evaporate at processing temperature; additive decomposition produces smoke; insufficient exhaust system
Lösung
1) Lower processing temperature to reduce volatilization; 2) Increase exhaust system capacity; 3) Select low-volatility raw material grade
Wichtigste Erkenntnis
Large smoke is caused by volatiles evaporation; temperature reduction and exhaust are the key
