Screw parameters not matching the material, poor extrusion quality
ظاهرة المشكلة
Screw parameters not matching the material, poor extrusion quality
تحليل الأسباب
Screw compression ratio improper, uneven plasticization
Screw L/D ratio improper, insufficient mixing
Screw head design improper, pressure fluctuation
Screw does not match the melting characteristics of cellulose acetate butyrate
Screw wear, plasticization efficiency decreased
الحل
Select an extrusion screw suitable for cellulose acetate butyrate
Compression ratio 3.0-3.5 is generally applicable
L/D ratio 24-30:1 recommended for extrusion
Select the screw head design according to cellulose acetate butyrate
Regularly check screw wear
الخلاصة الأساسية
The extrusion screw needs to match the material
