ASA continuous temperature resistance exceeded
문제 현상
After long-term use in high-temperature environments, ASA products soften and deform, dimensions become unstable, and performance decays sharply near the heat deflection temperature.
원인 분석
ASA continuous use temperature is medium; when approaching the heat deflection temperature, the modulus decreases significantly; creep accumulates under long-term heating under load; the actual temperature in enclosed spaces in summer often exceeds design expectations.
해결 방법
①Select materials according to actual maximum working condition temperature and leave margin; ②consider heat-resistant modified grades for high-temperature conditions; ③structural design reduces thermal load on load-bearing parts; ④thermal aging test verifies long-term dimensional stability.
핵심 요약
The temperature resistance boundary of ASA is at a medium level, and high-temperature applications require margin evaluation; creep is the invisible killer of long-term thermal load; measured working condition temperature is more reliable than theoretical values.
