Fenómeno do problema
HDPE products blended with recycled material have more bubbles
Análise das causas
Recycled material stored exposed absorbs water and contains pollutants, bringing in moisture and impurities; when troubleshooting on site, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience; this mechanism has been repeatedly verified by industry data and should be confirmed first during troubleshooting
Solução
Dry recycled material at 80-90℃ for 2 hours; control the blending ratio; store sealed after crushing; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Conclusão principal
HDPE recycled material should be dried and used in limited quantity; 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 similar future problems
