Control of winding abnormality in PEOX coating bandages
Problem Phenomenon
During PEOX coating production of bandages, the problem of large fluctuation in winding occurs.
Cause Analysis
Mainly due to the processing temperature deviating from the window +65-95°C, moisture content >0.3% exceeding the standard, and shear heat accumulation.
Solution
Strictly control the temperature within the recommended range, fully dry the material to moisture content <0.1%, and reduce the screw speed.
Key Takeaway
PEOX processing requires precise control of the three elements of temperature, humidity, and residence time.
