PMMA Drying Air Volume
문제 현상
In a large-capacity drying hopper, PMMA is dried unevenly between the top and bottom
원인 분석
The air volume does not match the loading amount, and the high resistance of the material layer causes uneven drying; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience; this mechanism has been repeatedly verified by industry literature and should be confirmed first during troubleshooting
해결 방법
Calculate the air volume at about 1m³/h per kilogram of material; do not load more than 80%; add a disperser to the hopper; after adjustment, take samples continuously to verify the effect, and resume mass production only after confirming stability
핵심 요약
Drying air volume should be calculated to match the loading amount; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a reference for troubleshooting similar problems in the future
