A large amount of smoke and white fumes is produced during PET '2079851475616104452, the working environment deteriorates, and products have an odor.
Análisis de la causa
Insufficient '2079851475616104451 with high moisture content vaporizing at high temperature; excessive processing temperature volatilizes low-molecular substances; oligomer content is high.
Solución
Ensure full drying (moisture ≤0.003%); reduce processing temperature; select low-oligomer raw materials; install a ventilation system.
Conclusión clave
PET '2079851475616104452 smoke mainly originates from moisture and low-molecular volatiles.
