Glass fiber feeding difficulty during extrusion pelletizing
문제 현상
Continuous glass fiber yarns pile up and tangle at the feed port and cannot feed normally
원인 분석
The feed section design does not adapt to the feeding characteristics of long fibers; the compression ratio of the screw compression section is too large, blocking fiber conveying; the glass fiber yarns are not fully opened
해결 방법
Optimize the feed port design and the feed section channel depth; reduce the compression ratio to 1.5-1.8:1 to adapt to long fibers; use a side feeding device to add glass fiber at the middle and rear sections
핵심 요약
The feeding method of long glass fibers is the key to determining fiber retention length and dispersion uniformity
