PA66 sealed conveying system
ظاهرة المشكلة
Centralized feeding system conveys dried PA66 to machines, moisture content exceeds standard afterward
تحليل الأسباب
Conveying lines use ordinary compressed air or open conveying; dried material re-absorbs moisture from humid air during conveying; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience
الحل
Dried material conveying uses closed-loop dry air conveying system, lines heat-preserved; conveying time controlled within 10 minutes; machine hopper capacity configured for 30-minute usage; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
الخلاصة الأساسية
Dried material conveying must be closed-loop to keep dry, small-capacity machine hoppers reduce exposure; 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 subsequent similar problems
