POM wear-resistant modified grades

Fenómeno do problema
POM sliding parts wear fast and are noisy, and squeal under high-load rubbing
Análise das causas
Although pure POM has good self-lubrication, wear intensifies and squealing noise is generated under high-load PV conditions; PTFE or silicone oil modified grades significantly improve wear resistance and noise reduction
Solução
①Select PTFE or silicone oil modified wear-resistant grades for high PV conditions; ②note that PTFE modification does not change thermal stability, and temperature discipline remains the same; ③manage the surface roughness matching of mating parts
Conclusão principal
Wear-resistant modification is the upgrade route for POM sliding parts; modification does not change temperature discipline, and the processing window and ventilation requirements remain unchanged; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
