EMA Extrusion Screen Pack Frequent Clogging
Sorun Belirtisi
EMA extrusion requires screen replacement every 2-3h; clogging causes sudden pressure rise and output drop
Neden Analizi
Many gel particles and impurities in the raw material; screen mesh too high, intercepting a large number of particles; filler or color masterbatch agglomerates clog the screen
Çözüm
1) Select raw material with low gel content; 2) Adopt stepped screens of 40/80/120 mesh; 3) Add filler and color masterbatch by the masterbatch method to reduce agglomeration; 4) Install an automatic screen changer to reduce downtime
Temel Çıkarım
Screen clogging is caused by impurities and improper configuration; raw material control and stepped screens are key
