Particle Sticking in PBT Extrusion Pelletizing
ظاهرة المشكلة
After PBT recycled material is pelletized, the particles stick to each other and agglomerate, making them unusable.
تحليل الأسباب
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.
الحل
Lower the water bath temperature and increase the water bath length; keep the pelletizing knife sharp; use pneumatic conveying to cool the particles.
الخلاصة الأساسية
PBT pelletizing sticking affects subsequent processing.
