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