PC Weather Resistance Modification
Fenómeno del problema
[Problem Phenomenon] PC outdoor products require weather resistance; pure PC is insufficient
Análisis de la causa
PC with UV absorber/carbon black modification or surface coating improves weather resistance; outdoor lamps and building parts adopt weather-resistant solutions; when troubleshooting on site, verify each item according to this mechanism one by one, and avoid blindly adjusting the machine based on experience alone
Solución
Select weather-resistant grades or coatings for outdoor parts; carbon black grades have good weather resistance but are black; xenon lamp aging verification; after adjustment, take samples continuously to verify the effect, and resume mass production only after confirming stability
Conclusión clave
PC outdoors relies on weather-resistant modification or coating; 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
