ABS flame-retardant part drying protection
문제 현상
ABS flame-retardant part drying temperature >80°C causes thermal degradation of the flame retardant, resulting in performance failure.
원인 분석
ABS flame-retardant grades are sensitive to drying temperature; >80°C causes sensitive flame retardants to thermally degrade before reaching the screw; 75-80°C×2-3 hours; additive protection; performance retention.
해결 방법
①Flame-retardant parts 75-80°C×2-3 hours; ②avoid >80°C; ③awareness of additive protection; ④performance verification; ⑤supplier confirmation.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
핵심 요약
The drying temperature upper limit of ABS flame-retardant parts is additive protection; 75-80°C is the safe zone; verification ensures flame-retardant performance.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
