PCABS flame retardant grade temperature
ظاهرة المشكلة
【Problem Phenomenon】Flame retardant PC/ABS processed at general temperature, flame retardant decomposes and fails
تحليل الأسباب
Flame retardant grades have a narrow processing temperature window: too high, the flame retardant decomposes and fails and produces gas; halogen-free phosphorus flame retardants are more temperature sensitive; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based on experience alone
الحل
Flame retardant grades take the middle-lower limit of the temperature window; check the data sheet temperature upper limit; if discoloration and gas generation occur, lower the temperature to verify; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
الخلاصة الأساسية
PC/ABS flame retardant material takes the lower temperature limit, flame retardants fear high temperature; 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
