Control of viscosity abnormality in PEOX blown film medical products
Problembeschreibung
During PEOX blown film production of medical products, the problem of uneven viscosity occurs.
Ursachenanalyse
Mainly due to the processing temperature deviating from the window +70-90°C, moisture content >0.3% exceeding the standard, and insufficient cooling.
Lösung
Strictly control the temperature within the recommended range, fully dry the material to moisture content <0.1%, and strengthen cooling.
Wichtigste Erkenntnis
PEOX processing requires precise control of the three elements of temperature, humidity, and residence time.
