POE surface gloss poor
Problembeschreibung
POE product surface gloss <60%, below 80% requirement, dull appearance
Ursachenanalyse
Mold surface rough Ra>0.4μm; POE crystallinity high, surface microcrystals scatter light; cooling rate improper
Lösung
1) Polish mold to Ra<0.1μm mirror finish; 2) Raise mold temperature to delay crystallization and reduce scattering; 3) Add nucleating agent to control crystal size
Wichtigste Erkenntnis
Poor gloss is caused by mold roughness and crystallization scattering; polishing mold and controlling crystallization are key
