Ambient temperature and humidity changes affect processing stability and product quality
Problembeschreibung
Ambient temperature and humidity changes affect processing stability and product quality
Ursachenanalyse
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)
Lösung
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
Wichtigste Erkenntnis
The environment needs humidity and temperature stability control
