PC flame retardant grade temperature
Fenómeno del problema
【Problem Phenomenon】Flame retardant PC processed at general temperature, flame retardant decomposes
Análisis de la causa
Flame retardant PC (especially bromine-based) has a narrow temperature window; excessive temperature decomposes the flame retardant causing failure and gas generation; temperature takes the lower limit of the window；During on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience
Solución
Flame retardant material temperature takes the lower limit of the window; check data sheet upper limit; lower temperature immediately upon discoloration and gas generation；After adjustment, take continuous samples 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
Conclusión clave
PC flame retardant material fears high temperature, temperature takes the lower limit；After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence；Include this case in the defect archive as a reference for troubleshooting similar problems in the future
