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