PCABS Flame-Retardant Part Discoloration
Sorun Belirtisi
[Problem Phenomenon] Flame-retardant PC/ABS discolors after processing, raising doubts about flame retardant performance
Neden Analizi
Flame retardant thermally decomposes and discolors; the temperature upper limit is lower than general grades; halogen-free phosphorus-based is more sensitive; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
Çözüm
Take the lower limit of the temperature window for flame-retardant materials; verify flame retardancy retention upon discoloration; check the upper limit on the data sheet; 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
Temel Çıkarım
PC/ABS flame-retardant materials fear high temperature; check temperature first upon discoloration; 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
