TPU Regrind Drying
Sorun Belirtisi
TPU products blended with regrind show bubbles and performance decline
Neden Analizi
Regrind absorbs moisture and accumulates heat history; elastomer performance is sensitive to degradation; when troubleshooting on site, verify item by item according to this mechanism to avoid blindly adjusting the machine based only on experience; this mechanism has been repeatedly verified by industry literature and should be confirmed first during troubleshooting
Çözüm
Dry regrind separately for 3 hours; blending ratio not exceeding 20%; regrind prohibited for performance parts; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability; change only one variable at a time and record parameter changes to facilitate locating effective measures
Temel Çıkarım
TPU regrind is dried and limited, and prohibited for performance parts; 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 problems in the future
