PPO Cumulative Drying Time Upper Limit
문제 현상
【Problem Phenomenon】PPO pellets show abnormal processing performance after repeated drying or long-time baking and storage
원인 분석
The NHP9023 data sheet clearly states a cumulative drying time upper limit of 8 hours; repeated drying accumulates heat history and affects the material, and after exceeding the limit, flowability and hue drift
해결 방법
Cumulative drying time is controlled within 8 hours; use up promptly after drying to avoid repeated re-baking; record drying history of remaining material and use it first; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
핵심 요약
PPO cumulative drying is capped at 8 hours, and re-baking times must be recorded; 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
