EEA Surface Microcracks
Problembeschreibung
0.05-0.2mm microcracks appear on the surface of EEA products, affecting appearance and strength
Ursachenanalyse
Internal stress of EEA products is too large, exceeding the material yield stress; environmental stress cracking; stress concentration in product design
Lösung
1) Annealing treatment to release internal stress; 2) Product design to avoid sharp corners and stress concentration; 3) Select high-molecular-weight EEA to improve crack resistance
Wichtigste Erkenntnis
Microcracks are caused by excessive internal stress; annealing and crack-resistant design are key
