Ambient temperature and humidity changes affect processing stability and product quality
Fenómeno do problema
Ambient temperature and humidity changes affect processing stability and product quality
Análise das causas
High ambient humidity, raw material moisture absorption accelerates
Ambient temperature fluctuation affects equipment temperature control
Poor workshop ventilation affects drying effect
Seasonal changes require process parameter adjustment
Cellulose acetate butyrate has high sensitivity to ambient humidity (PA type especially obvious)
Solução
Control workshop humidity ≤60%RH
Stabilize workshop temperature
Improve workshop ventilation
Adjust process parameters when seasons change
PA-type raw materials stored sealed and used quickly
Conclusão principal
The environment needs humidity and temperature stability control
