PMMA Color Masterbatch Drying
문제 현상
Bubbles appear in PMMA products with color masterbatch added
원인 분석
The color masterbatch carrier absorbs moisture without being dried, and the introduced moisture vaporizes 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.; this mechanism has been repeatedly verified by industry data and should be confirmed first during troubleshooting
해결 방법
Dry color masterbatch under the same conditions as the base material; select PMMA-dedicated color masterbatch; oven-dry dampened color masterbatch; After adjustment, continuously sample 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.
핵심 요약
Synchronized drying of color masterbatch is an anti-bubble detail; 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.
