PP Anti-Static Modification
Fenómeno del problema
[Problem Phenomenon] PP for electronic packaging and coal mines needs anti-static properties
Análisis de la causa
PP is insulating and easily accumulates static electricity; anti-static modification (anti-static agents/conductive fillers) is used for electronic packaging, coal mine safety products, and cleanroom supplies; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based on experience alone
Solución
Select modified PP for anti-static parts; verify surface resistance according to standards; select carbon black/carbon fiber grades for conductive parts; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Conclusión clave
PP anti-static relies on modification; used in both electronic packaging and coal mines; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshooting reference for similar future problems
