PMMA Bonding Bubbles
ظاهرة المشكلة
Bubbles and whitening appear on PMMA bonding surfaces
تحليل الأسباب
Adhesive curing heat release or poor solvent volatilization traps bubbles in the bonding layer; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience; this mechanism has been repeatedly verified by industry literature and should be confirmed first during troubleshooting
الحل
Apply adhesive in thin, uniform layers; ventilate the curing environment; choose low-bubble special adhesives; after adjustment, take samples continuously to verify the effect, and resume mass production only after confirming stability; change only one variable at a time and record parameter changes to facilitate locating effective measures
الخلاصة الأساسية
Bonding quality relies on application process and adhesive selection; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a reference for troubleshooting similar problems in the future
