Heavy smoke in PU processing

Problembeschreibung

During PU processing, smoke and large amounts of volatiles overflow from the vent

Ursachenanalyse

Low molecular volatiles in PU evaporate at processing temperature; additives decompose producing smoke; exhaust system insufficient

Lösung

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

Wichtigste Erkenntnis

Heavy smoke is caused by volatiles evaporation; temperature reduction and exhaust are key

PU processing smoke volatiles exhaust system temperature reduction
