HDPE melt temperature range
Problembeschreibung
The HDPE melt temperature was set to 290℃, and the product turned yellow with abnormal odor
Ursachenanalyse
When the HDPE melt exceeds 280℃, thermal oxidative degradation accelerates, the color turns yellow and an odor is produced; when troubleshooting on site, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
Lösung
Control the melt temperature at 200-280℃; take 220-260℃ for '2079851475616104452; empty the overheated material; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Wichtigste Erkenntnis
The upper limit of HDPE melt is 280℃, and overheating causes oxidative degradation; 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
