HDPE drying temperature
Sorun Belirtisi
After HDPE is dried for a long time above 100℃, the melt flow deteriorates
Neden Analizi
Excessive drying slightly oxidizes the HDPE surface, affecting processing fluidity and product performance; when troubleshooting on site, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
Çözüm
HDPE drying at 80-90℃ for 1-2 hours; avoid high-temperature long-time drying; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Temel Çıkarım
HDPE drying only needs low temperature and short time; 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
