PVB Glass Cleaning and Drying
Problem Phenomenon
Glass cleaning and drying before laminated glass assembly is not thorough, PVB adhesion is poor.
Cause Analysis
Glass surface cleanliness; water stain residue; drying temperature and time; cleaning agent selection; surface energy condition.; When troubleshooting on site, verify item by item according to this mechanism, avoiding blind machine adjustment based only on experience
Solution
①Glass cleaning process optimization; ②Sufficient drying without water stains; ③Cleaning agent compatibility; ④Surface energy inspection.; After adjustment, continuously sample to verify the effect, confirm stability before resuming mass production
Key Takeaway
Surface preparation for PVB-glass adhesion is the foundation; cleaning and drying is the premise; inspection ensures quality.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
