Sticking of PET during drying
Sorun Belirtisi
PET pellets stick and agglomerate in the dehumidifying dryer, cannot discharge normally.
Neden Analizi
Drying temperature set too high (exceeding PET softening point), temperature control system failure, material stays too long in high-temperature zone, amorphous PET low softening.
Çözüm
Strictly control drying temperature ≤175°C; calibrate temperature control; avoid long residence (>8h); pre-crystallize amorphous PET first.
Temel Çıkarım
PET drying sticking requires strict control of temperature and residence time.
