Glass Fibre extrusion pelletizing connected pellets
Sorun Belirtisi
During Glass Fibre extrusion pelletizing, pellets connected between each other, not completely cut, forming bead-string shape
Neden Analizi
Glass Fibre soft, during pelletizing the knife cuts in but elastic recovery makes cut surfaces re-bond; pelletizing water temperature too low <40°C, not fully solidified; cutter speed not matched with extrusion speed
Çözüm
1) Raise pelletizing water temperature to 50-60°C, cut after full solidification; 2) increase cutter speed to ensure fast cutting; 3) cutter gap 0.01-0.02mm ensures clean cutting; 4) rotary cutter instead of flat cutting to reduce connected pellets
Temel Çıkarım
Connected pellets are caused by elastic recovery and low-temperature pelletizing; high-temperature water cutting and fast cutting are key
