ASA garden furniture low-temperature brittle cracking
문제 현상
ASA outdoor furniture shows cracking and fracture complaints in winter, passes room temperature inspection, and low-temperature drop test reproduces brittle cracking failure.
원인 분석
ASA low-temperature toughness decays as temperature decreases, and notched impact strength decreases significantly below the embrittlement-sensitive range; outdoor furniture winter low temperature superimposes load concentration; toughness further decreases after aging.
해결 방법
①Verify low-temperature impact performance for applications in cold regions; ②structure eliminates sharp corner notches; ③post-aging low-temperature combined test evaluates the full life cycle; ④if necessary, select low-temperature modified grades.
핵심 요약
The low-temperature performance of ASA outdoor parts must be included in design verification; passing room temperature does not mean winter safety; combined aging and low-temperature testing is closest to real life.; After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
