Large volatile smoke during PBT '2079851475616104452
Sorun Belirtisi
A large amount of white smoke or pungent odor is generated during PBT '2079851475616104452.
Neden Analizi
Insufficient drying causes moisture vaporization, the processing temperature is too high causing low molecular oligomers to volatilize, and flame retardants or other additives decompose at high temperature.
Çözüm
Fully dry to moisture <0.02%; reduce the processing temperature to 240-260°C; select low-volatility additives; strengthen workshop ventilation.
Temel Çıkarım
PBT injection smoke is a product of moisture and additive decomposition.
