ظاهرة المشكلة
Obvious irritating odor in the PVA processing workshop
تحليل الأسباب
PVA releases odorous volatiles (such as acetic acid, formaldehyde, etc.) at processing temperature; additive decomposition releases odor
الحل
1) Control processing temperature within the PVA recommended range to reduce decomposition; 2) Strengthen workshop ventilation and exhaust; 3) Add absorbent to neutralize odor
الخلاصة الأساسية
Large odor is caused by PVA decomposition and volatilization; temperature control and ventilation are the key
