Control of dissolution rate abnormality in PEOX coating medical products
Problembeschreibung
During PEOX coating production of medical products, the problem of large fluctuation in dissolution rate occurs.
Ursachenanalyse
Mainly due to the processing temperature deviating from the window +65-95°C, moisture content >0.5% exceeding the standard, and shear heat accumulation.
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.
