PTFE Laminate Delamination
Fenómeno do problema
PTFE laminate layers separate and peel, the multilayer structural integrity is destroyed, and function fails.
Análise das causas
Insufficient interlayer bonding or sintering; interlayer surface contamination (oil, dust); uneven pressure during lamination causes inconsistent bonding; interlayer adhesion differences between different PTFE grades.
Solução
①Thoroughly clean surfaces before lamination; ②Apply uniform heat and pressure to ensure bonding; ③Select compatible PTFE grades to ensure interlayer adhesion; ④Include delamination inspection in non-destructive testing.
Conclusão principal
Cleanliness and pressure uniformity of PTFE laminates determine interlayer quality; grade compatibility is easily overlooked; non-destructive testing is quality assurance.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
