PPO Alloy Grade Phase Separation
문제 현상
[Problem Phenomenon] Delamination and uneven performance of PPO/PS or PPO/PA alloy products
원인 분석
Improper processing temperature and shear of the alloy system cause abnormal phase distribution; PPO/PA is a semi-crystalline system, and its crystallization behavior is more affected by the process; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
해결 방법
Process according to the alloy grade's dedicated process window; trace temperature and shear records for phase-separated parts; monitor batch performance sampling; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
핵심 요약
For PPO alloy delamination check the process window; stable phase means stable performance; 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
