Particle Sticking in PBT Extrusion Pelletizing
Sorun Belirtisi
After PBT recycled material is pelletized, the particles stick to each other and agglomerate, making them unusable.
Neden Analizi
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.
Çözüm
Lower the water bath temperature and increase the water bath length; keep the pelletizing knife sharp; use pneumatic conveying to cool the particles.
Temel Çıkarım
PBT pelletizing sticking affects subsequent processing.
