Control of viscosity abnormality in PEOX extrusion water-soluble bags
Problembeschreibung
During PEOX extrusion production of water-soluble bags, the problem of not up to standard viscosity occurs.
Ursachenanalyse
Mainly due to the processing temperature deviating from the window +60-100°C, moisture content >0.5% exceeding the standard, and excessively long residence time.
Lösung
Strictly control the temperature within the recommended range, fully dry the material to moisture content <0.1%, and reduce the screw speed.
Wichtigste Erkenntnis
PEOX processing requires precise control of the three elements of temperature, humidity, and residence time.
