PVC Flame Retardant Application
ظاهرة المشكلة
PVC was chosen for a flame retardant part but failed the glow-wire test
تحليل الأسباب
PVC is flame retardant but contains hydrogen, and some high flame retardant grade tests still require modification; during on-site troubleshooting, 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 data and should be confirmed first during troubleshooting
الحل
Select flame-retardant modified grades for high flame retardant requirements; verify according to test standards; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability; change only one variable at a time and record parameter changes to facilitate locating effective measures
الخلاصة الأساسية
PVC has a flame retardant foundation, but high grades still require modification; 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 in the future
