PPO Steam-Resistant Part Failure
Problembeschreibung
Products for PPO steam-resistant applications show performance degradation after long-term use, and service life in high-temperature and high-humidity environments is lower than expected.
Ursachenanalyse
Although PPO has outstanding water and steam resistance, long-term high temperature and high humidity still have cumulative effects; processing defects such as internal stress and microcracks become the starting points of degradation; use temperature exceeding the recommended range accelerates aging.
Lösung
①Design according to the -127~121℃ long-term use range; ②low-stress process to reduce degradation starting points; ③verify service life with damp heat aging tests; ④regular performance tracking.
Wichtigste Erkenntnis
PPO's steam resistance advantage must be exerted within design limits; processing quality determines whether the advantage can be realized; long-term verification data guides application boundaries.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
