Heavy Smoke in EVOH Processing
문제 현상
During EVOH processing, smoke and large amounts of volatiles escape from the vent
원인 분석
Low molecular volatiles in EVOH evaporate at processing temperature; additive decomposition produces smoke; exhaust system insufficient
해결 방법
1) Reduce processing temperature to decrease volatilization; 2) Increase exhaust system capacity; 3) Select low-volatile raw material grade
핵심 요약
Heavy smoke is caused by volatile evaporation; cooling and exhaust are key
