TPU Moisture Reabsorption Speed
문제 현상
Dried TPU was used after being placed in the workshop for 1 hour, and bubbles reappeared
원인 분석
TPU reabsorbs moisture extremely fast; dried material exposed to humid air reabsorbs excessive moisture within 30-60 minutes; when troubleshooting on site, verify item by item according to this mechanism to avoid blindly adjusting the machine based only on experience
해결 방법
Dried material stored in an insulated drying hopper; usage time limited to within 30 minutes; re-dry if exceeded; 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
TPU dried material usage time limit is managed at 30 minutes; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshooting reference for similar problems in the future
