Large smoke in PVA processing
Sorun Belirtisi
During PVA processing, large amount of smoke and volatiles overflow from the vent
Neden Analizi
Low molecular volatiles in PVA evaporate at processing temperature; additive decomposition produces smoke; insufficient exhaust system
Çözüm
1) Lower processing temperature to reduce volatilization; 2) Increase exhaust system capacity; 3) Select low-volatility raw material grade
Temel Çıkarım
Large smoke is caused by volatiles evaporation; temperature reduction and exhaust are the key
