PVB laminated glass ceramic ink area adhesion is poor, bubbles and delamination.
원인 분석
Ceramic ink compatibility with glass/PVB; ink curing degree; surface energy differences; ink thickness uniformity.; When troubleshooting on site, verify item by item according to this mechanism, avoiding blind machine adjustment based only on experience
해결 방법
①Ink compatibility verification; ②Curing process specification; ③Ink thickness control; ④Adhesion testing.; After adjustment, continuously sample to verify the effect, confirm stability before resuming mass production
핵심 요약
Adhesion in PVB ink areas is a special challenge; compatibility is a material issue; testing and verification are indispensable.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
