Adhesive solvents attack the PMMA surface, producing microcracks and whitening; 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
Çözüm
Choose low-attack adhesives; precisely control adhesive application without overflow; polish and repair whitened areas; 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
Temel Çıkarım
Bonding whitening is solvent attack; adhesive selection and quantity control are key; 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
