PEI Creep Resistance Under High Temperature and Stress
Fenómeno del problema
PEI's creep behavior appears under high temperature and high stress levels; dimensions change under long-term load.
Análisis de la causa
PEI has creep resistance under high temperature and stress levels, but extreme conditions still need consideration; apparent modulus changes; design stress and temperature limits; long-term data support.
Solución
①Design stress and temperature according to creep data; ②carefully evaluate high temperature and high stress; ③track long-term deformation; ④set safety factors reasonably.; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
Conclusión clave
PEI creep resistance is a relative advantage; extreme conditions still need data; long-term tracking verifies the design.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
