Control of transparency abnormality in PEOX calendering pharmaceutical films
ظاهرة المشكلة
During PEOX calendering production of pharmaceutical films, the problem of uneven transparency occurs.
تحليل الأسباب
Mainly due to the processing temperature deviating from the window +70-90°C, moisture content >0.5% exceeding the standard, and shear heat accumulation.
الحل
Strictly control the temperature within the recommended range, fully dry the material to moisture content <0.1%, and strengthen cooling.
الخلاصة الأساسية
PEOX processing requires precise control of the three elements of temperature, humidity, and residence time.
