Surface Chalking of LCP Products After Xenon Lamp Aging
Fenómeno del problema
【Problem Phenomenon】Outdoor LCP products show slight surface chalking and discoloration after long-term light exposure
Análisis de la causa
LCP's weather resistance is average; long-term ultraviolet action degrades and chalks the surface molecules; outdoor applications need to evaluate weather resistance or add protection; during on-site troubleshooting, verify item by item according to this mechanism to avoid blindly adjusting the machine based solely on experience
Solución
For outdoor parts, select weather-resistant modified grades or surface coating protection; use outdoors only after xenon lamp aging verification meets the standard; for non-weather-resistant occasions, avoid storage in direct sunlight; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Conclusión clave
Weather resistance is not LCP's strength; outdoor applications must select weather-resistant grades plus verification; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshooting reference for subsequent similar problems
