Particle Sticking in PBT Extrusion Pelletizing
문제 현상
After PBT recycled material is pelletized, the particles stick to each other and agglomerate, making them unusable.
원인 분석
The pelletizing water temperature is too high and the particles are not fully cooled; the pelletizing knife is blunt, causing irregular particle shapes; the particle surface temperature is high.
해결 방법
Lower the water bath temperature and increase the water bath length; keep the pelletizing knife sharp; use pneumatic conveying to cool the particles.
핵심 요약
PBT pelletizing sticking affects subsequent processing.
