EMA surface microcracks
문제 현상
0.05-0.2mm microcracks appear on EMA product surface, affecting appearance and strength
원인 분석
Internal stress in EMA products too large, exceeding material yield stress; environmental stress cracking; stress concentration in product design
해결 방법
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
핵심 요약
Microcracks are caused by excessive internal stress; annealing and crack-resistant design are key
