POE internal unmelted particles
Problembeschreibung
POE product interior shows unmelted transparent or semi-transparent particles
Ursachenanalyse
Screw plasticizing capacity insufficient, temperature low; feeding amount too large, exceeding plasticizing capacity; POE melting temperature high
Lösung
1) Raise 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; raising temperature and reducing feeding are key
