Control of strength abnormality in PEOX extrusion pharmaceutical films
Fenómeno do problema
During PEOX extrusion production of pharmaceutical films, the problem of unstable strength occurs.
Análise das causas
Mainly due to the processing temperature deviating from the window +60-100°C, moisture content >0.3% exceeding the standard, and insufficient cooling.
Solução
Strictly control the temperature within the recommended range, fully dry the material to moisture content <0.1%, and reduce the screw speed.
Conclusão principal
PEOX processing requires precise control of the three elements of temperature, humidity, and residence time.
