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