PVB Laminated Glass Edge Delamination Bubbles
Fenómeno del problema
Laminated glass edge delamination and bubbles, accounting for 15% of production waste and over 85% of after-sales complaints, poor edge sealing.
Análisis de la causa
Poor edge sealing after roller pressing; too fast roller pressing speed; low roller pressing temperature (cold glass); autoclave pressure released too early; tempered glass edge deformation too large; PVB pattern too fine with poor venting.
Solución
①Optimize roller pressing process for edge sealing; ②Control roller pressing speed and temperature; ③Standardize autoclave pressure release procedure; ④Glass edge quality inspection; ⑤PVB pattern design matching venting.
Conclusión clave
PVB edge defects are the most serious problem of laminated glass; roller pressing and autoclave processes are the key; glass quality and PVB design jointly influence.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
