PVC products with color masterbatch show bubbles and color difference
تحليل الأسباب
Masterbatch carrier absorbs moisture or poor compatibility with PVC, poor dispersion; during on-site troubleshooting, verify item by item according to this mechanism, avoid blindly adjusting the machine based solely on experience; this mechanism has been repeatedly verified by industry data and should be confirmed first during troubleshooting
الحل
Choose PVC-dedicated masterbatch; masterbatch dried; dispersion effect verified; 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
الخلاصة الأساسية
PVC masterbatch needs dedicated type, drying plus dispersion verification; 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 similar problems later
