PVB Glass Matching
ظاهرة المشكلة
PVB laminated glass flatness mismatch, stress concentration and bubbles.
تحليل الأسباب
Tempered glass flatness differences; two pieces of glass matching; PVB thickness compensation capability; edge deformation; stress distribution.; When troubleshooting on site, verify item by item according to this mechanism, avoiding blind machine adjustment based only on experience
الحل
①Glass flatness inspection and pairing; ②Sufficient PVB thickness; ③Edge quality control; ④Stress detection.; After adjustment, continuously sample to verify the effect, confirm stability before resuming mass production
الخلاصة الأساسية
PVB glass matching is the premise of lamination quality; inspection and pairing is an effective means; thickness compensation has limitations.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
