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