Control of dissolution rate abnormality in PEOX coating medical products
Fenómeno del problema
During PEOX coating production of medical products, the problem of large fluctuation in dissolution rate occurs.
Análisis de la causa
Mainly due to the processing temperature deviating from the window +65-95°C, moisture content >0.5% exceeding the standard, and shear heat accumulation.
Solución
Strictly control the temperature within the recommended range, fully dry the material to moisture content <0.1%, and strengthen cooling.
Conclusión clave
PEOX processing requires precise control of the three elements of temperature, humidity, and residence time.
