Screw parameters not matching the material, poor extrusion quality
문제 현상
Screw parameters not matching the material, poor extrusion quality
원인 분석
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
해결 방법
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
핵심 요약
The extrusion screw needs to match the material
