PCABS drying equipment selection
문제 현상
【Problem Phenomenon】Ordinary hot air oven drying PC/ABS has fluctuating effect, batch silver streaks in the rainy season
원인 분석
PC/ABS moisture content requirements are strict, only a dehumidifying dryer with stable dew point can guarantee the endpoint; hot air ovens are greatly affected by environmental humidity and fail in the rainy season; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based on experience alone
해결 방법
Equip a dehumidifying dryer with dew point below -30℃; hot air ovens only for low-requirement parts; intensify moisture content sampling in the rainy season; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
핵심 요약
PC/ABS drying needs a dehumidifier as the backstop, hot air ovens depend on the weather; 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
