Heavy smoke in PU processing
ظاهرة المشكلة
During PU processing, smoke and large amounts of volatiles overflow from the vent
تحليل الأسباب
Low molecular volatiles in PU evaporate at processing temperature; additives decompose producing smoke; exhaust system insufficient
الحل
1) Lower processing temperature to reduce volatilization; 2) Increase exhaust system capacity; 3) Select low-volatility raw material grade
الخلاصة الأساسية
Heavy smoke is caused by volatiles evaporation; temperature reduction and exhaust are key
