PVB Thickness Selection
Problem Phenomenon
Improper PVB interlayer thickness selection: too thin gives insufficient compensation, too thick gives high cost.
Cause Analysis
PVB thickness 0.38~1.52mm selected according to application; glass flatness compensation; safety performance requirements; cost balance.; during on-site troubleshooting, verify item by item according to this mechanism, avoid blindly adjusting the machine based solely on experience
Solution
①Select thickness according to application and glass quality; ②Increase thickness when flatness is poor; ③Safety standard compliance; ④Cost optimization.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
PVB thickness selection is a balance of performance and cost; glass quality is an important input; standard compliance is the bottom line.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
