Glass Fibre hydrolysis aging
문제 현상
Glass Fibre product in humid-hot environment mechanical properties drop >25%
원인 분석
Glass Fibre contains polar groups, hydrolytic chain scission under humid-hot conditions; ester bonds/amide bonds etc. sensitive to water
해결 방법
1) Select low-polarity-content grade to reduce hydrolysis tendency; 2) add anti-hydrolysis stabilizer; 3) coat product surface with waterproof layer
핵심 요약
Hydrolysis aging is caused by polar groups' sensitivity to water; selecting low-polarity grade is key
