Large odor in PVA processing
Fenómeno del problema
Obvious irritating odor in the PVA processing workshop
Análisis de la causa
PVA releases odorous volatiles (such as acetic acid, formaldehyde, etc.) at processing temperature; additive decomposition releases odor
Solución
1) Control processing temperature within the PVA recommended range to reduce decomposition; 2) Strengthen workshop ventilation and exhaust; 3) Add absorbent to neutralize odor
Conclusión clave
Large odor is caused by PVA decomposition and volatilization; temperature control and ventilation are the key
