POE extrusion surface rough
문제 현상
POE extruded product surface roughness Ra>5μm, exceeding requirement
원인 분석
Extrusion temperature too low <160°C, melt flow unstable; die inner wall rough or damaged; POE melt elasticity, die swell uneven
해결 방법
1) Raise extrusion temperature to 160-200°C; 2) Polish die inner wall to Ra<0.4μm; 3) Reduce extrusion rate 10-15%; 4) Add 0.3-0.5wt% external lubricant
핵심 요약
Surface roughness is caused by low-temperature extrusion and die defects; raising temperature and polishing the die are core countermeasures
