Heavy smoke in PU processing
Fenómeno del problema
During PU processing, smoke and large amounts of volatiles overflow from the vent
Análisis de la causa
Low molecular volatiles in PU evaporate at processing temperature; additives decompose producing smoke; exhaust system insufficient
Solución
1) Lower processing temperature to reduce volatilization; 2) Increase exhaust system capacity; 3) Select low-volatility raw material grade
Conclusión clave
Heavy smoke is caused by volatiles evaporation; temperature reduction and exhaust are key
