Frequent screen clogging in PU extrusion
Sorun Belirtisi
In PU extrusion, the screen needs to be replaced every 2-3h; clogging causes sudden pressure rise and output decrease
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 clogging the screen
Çözüm
1) Select raw material with low gel content; 2) Adopt stepped screens 40/80/120 mesh; 3) Add filler and color masterbatch by masterbatch method to reduce agglomeration; 4) Install 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
