MP surface microcracks
Problembeschreibung
MP product surface shows 0.05-0.2mm microcracks, affecting appearance and strength
Ursachenanalyse
MP product internal stress too large, exceeding the material yield stress; environmental stress cracking; product design stress concentration
Lösung
1) annealing to release internal stress; 2) product design avoiding sharp corners and stress concentration; 3) select high molecular weight MP to improve crack resistance
Wichtigste Erkenntnis
microcracks are caused by excessive internal stress; annealing and crack-resistant design are key
