Heavy smoke in PU processing

문제 현상

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

원인 분석

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

해결 방법

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

핵심 요약

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

PU processing smoke volatiles exhaust system temperature reduction
