PEEK Bonding and Surface Treatment
Sorun Belirtisi
【Problem Phenomenon】PEEK structural bonding strength is insufficient, and the adhesive interface separates
Neden Analizi
PEEK has low surface energy and strong chemical inertness, so direct bonding strength is limited; surface pretreatment such as chromic acid etching can significantly improve bonding force; epoxy, polyurethane, and silicone adhesives can all be selected
Çözüm
Chromic acid etching or plasma treatment of the surface before bonding; select epoxy or silicone system according to service temperature; perform shear strength verification on bonded joints; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
Temel Çıkarım
The success of PEEK bonding lies in surface pretreatment; inert surfaces must be activated; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshooting reference for similar problems in the future
