PVB Laminated Glass Optics
Problem Phenomenon
PVB laminated glass optical distortion, uneven thickness and stress.
Cause Analysis
PVB uneven thickness; glass flatness; lamination stress; cooling rate; optical inspection.; during on-site troubleshooting, verify item by item according to this mechanism, avoid blindly adjusting the machine based solely on experience
Solution
①PVB thickness uniformity; ②Glass quality; ③Lamination process optimization; ④Optical performance inspection.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
PVB laminated optical quality is a multi-factor combination; uniformity and stress management; inspection ensures delivery.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
