PMMA Adhesive Selection
문제 현상
Using the wrong adhesive causes the sheet to crack, or insufficient bonding strength causes debonding
원인 분석
Solvent-type and polymer-type adhesives have better adhesion than contact-type adhesives; when internal stress has not been relieved, solvents cause stress cracks; methylene chloride, polymer, and epoxy types are suitable for PMMA
해결 방법
①Temper at 60-90℃ to relieve stress before bonding; ②select solvent-type or polymer-type special adhesives; ③contact-type adhesives are only used for low-stress temporary fixing; after adjustment, take samples continuously to verify the effect, and resume mass production only after confirming stability
핵심 요약
For PMMA bonding, relieve stress before selecting the adhesive; solvent-type gives the best effect, but the premise is proper annealing; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
