Fast Thermal Aging of CMC
문제 현상
After aging at 80°C for 7 days, mechanical properties of CMC products decrease by >30%
원인 분석
CMC molecular chains break and degrade under thermal oxidation; antioxidant system is imperfect and protection is insufficient
해결 방법
1)Improve the antioxidant system 1010+168+DSTDP; 2)Select high-molecular-weight grade; 3)Add metal deactivator 0.05wt%
핵심 요약
Thermal aging is caused by thermal oxidation; improving the antioxidant system is the key
