PVA surface microcracks
Sorun Belirtisi
PVA product surface shows 0.05-0.2mm microcracks affecting appearance and strength
Neden Analizi
PVA product internal stress too large, exceeding the material yield stress; environmental stress cracking; product design stress concentration
Çözüm
1) Annealing treatment to release internal stress; 2) Product design to avoid sharp corners and stress concentration; 3) Select high molecular weight PVA to improve crack resistance
Temel Çıkarım
Microcracks are caused by excessive internal stress; annealing and crack-resistant design are the key
