EMA surface microcracks
Fenómeno del problema
0.05-0.2mm microcracks appear on EMA product surface, affecting appearance and strength
Análisis de la causa
Internal stress in EMA products too large, exceeding material yield stress; environmental stress cracking; stress concentration in product design
Solución
1) Annealing treatment to release internal stress; 2) Product design avoids sharp corners and stress concentration; 3) Select high molecular weight EMA to improve crack resistance
Conclusión clave
Microcracks are caused by excessive internal stress; annealing and crack-resistant design are key
