PMMA Moisture Content Standard
문제 현상
Bubbles appear intermittently in PMMA products, and the moisture content control standard is unknown
원인 분석
PMMA '2079851475616104452 moisture content generally requires below 0.04%, optical grade requires 0.02%, and moisture exceeding the standard vaporizes into bubbles in the melt; During on-site troubleshooting, verify item by item according to this mechanism to avoid blindly adjusting the machine based on experience alone.
해결 방법
Equip a moisture meter to judge according to grade requirements; optical grade strictly follows 0.02%; re-dry dampened material; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability.
핵심 요약
PMMA moisture content is controlled in grades by application, optical grade being the strictest; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence.; include this case in the defect archive as a troubleshooting reference for similar future problems.
