PC insufficient drying hidden brittle fracture
문제 현상
【Problem Phenomenon】PC products appear normal in appearance but break brittlely during assembly or dropping, a hidden failure
원인 분석
When drying insufficiency is slight, there are no silver streaks in appearance but the molecular weight has already decreased, and impact strength is greatly impaired; this hidden failure is the most dangerous, only exposed during assembly or use；During on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience
해결 방법
Moisture content strictly measured; impact strength sampling inspection; hidden brittle fracture traced to drying records；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
핵심 요약
Insufficient PC drying causes hidden brittle fracture; normal appearance does not mean qualification；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
