Frequent screen clogging in EVA extrusion
ظاهرة المشكلة
EVA extrusion requires screen replacement every 2-3h; clogging causes pressure surge and output decline
تحليل الأسباب
Many gel particles and impurities in raw material; screen mesh too high intercepting large amount of particles; filler or color masterbatch agglomeration clogging screen
الحل
1) Select raw material with low gel content; 2) Use 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
الخلاصة الأساسية
Screen clogging is caused by impurities and improper configuration; raw material control and stepped screens are key
