Heavy Smoke in EVOH Processing
ظاهرة المشكلة
During EVOH processing, smoke and large amounts of volatiles escape from the vent
تحليل الأسباب
Low molecular volatiles in EVOH evaporate at processing temperature; additive decomposition produces smoke; exhaust system insufficient
الحل
1) Reduce processing temperature to decrease volatilization; 2) Increase exhaust system capacity; 3) Select low-volatile raw material grade
الخلاصة الأساسية
Heavy smoke is caused by volatile evaporation; cooling and exhaust are key
