PPO Insulating Parts for High-Temperature Applications
Fenómeno do problema
[Problem Phenomenon] Insulating parts in high-temperature environments; ordinary insulating materials have insufficient heat distortion resistance
Análise das causas
PPO has a high heat distortion temperature and stable electrical properties over a wide temperature range, and can be used as insulating parts at relatively high temperatures; transformers and motor parts are typical scenarios; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
Solução
Select PPO high-heat-resistant grades for high-temperature insulating parts; check HDT according to working conditions; retest insulation after long-term thermal aging; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Conclusão principal
PPO for high-temperature insulation meets both heat distortion and electrical property standards; 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
