PVB Re-bubbling Phenomenon
ظاهرة المشكلة
Re-bubbling appears during the service period of laminated glass, residual air from roller pressing or PVB moisture weakens the bond.
تحليل الأسباب
Residual air trapped during roller pressing; high PVB moisture content weakens glass-film bonding; poor adhesion of ceramic ink to glass/PVB; service environment induces it.
الحل
①Sufficient roller pressing venting to prevent residue; ②Strict PVB moisture management; ③Ink adhesion verification; ④Service environment assessment.; After adjustment, continuously sample to verify the effect, confirm stability before resuming mass production
الخلاصة الأساسية
PVB re-bubbling is the delayed appearance of production defects; moisture and venting are prevention priorities; adhesion verification covers interfaces.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
