EMA internal unmelted particles
Problembeschreibung
Unmelted transparent or translucent particles appear inside EMA products
Ursachenanalyse
Screw plasticizing capacity insufficient with temperature too low; feeding amount too large exceeding plasticizing capacity; EMA melting temperature too high
Lösung
1) Increase processing temperature to ensure full melting; 2) Reduce feeding amount to match plasticizing capacity; 3) Increase screw mixing section
Wichtigste Erkenntnis
Unmelted particles are caused by insufficient plasticization; increasing temperature and reducing feeding are key
