ASA Low-Temperature Embrittlement
문제 현상
【Problem Phenomenon】ASA products toughness decreases in low-temperature environment, impact cracking
원인 분석
ASA low-temperature toughness is better than most styrenics but still decreases with temperature; notches and stress concentration points crack first at low temperature; during on-site troubleshooting, verify item by item according to this mechanism, avoid blindly adjusting the machine based only on experience
해결 방법
Low-temperature applications do low-temperature impact verification; structure rounded; toughened grades cover severe cold scenarios; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
핵심 요약
ASA low-temperature toughness has limits, severe cold parts verify and toughen; 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 subsequent similar problems
