PA66 raw material opening management
문제 현상
A whole package of PA66 opened and used over three days, third-day material products show silver streaks
원인 분석
After opening, material continuously absorbs moisture from the environment, third-day moisture content already exceeds 0.2%, original dried state failed; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience
해결 방법
Open in sub-packages by shift usage; unused material sealed with desiccant for storage; re-bake 2 hours before reuse; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
핵심 요약
Opened material is managed as wet material, sub-packaging, sealing plus re-baking; 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 subsequent similar problems
