Analysis of Color0Difference and Physical Property of Anti-Corrosion Coatings Used in Concrete Tank

콘크리트 수조 구조물에 사용하는 방식코팅재의 화학수 침지에 따른 색차 변화와 물리적 성질의 관계분석 기초 연구 -에폭시 수지계 도료를 중심으로-

This study deals with the analysis of color-difference and physical property of anti-corrosion coatings using at inside of concrete tank for drinking water. Because anti-corrosion coatings are effected by chemical attack, color and physical property are changed. So in this study when epoxy resin coatings of 3 types were received chemical attack by Cl- and NaOH, we present the co-relationship between color-difference and bond strength. For this study, we used the colorimetry, which can measure the degree of color difference on surface of materials. As the results, in case of Cl-, color change is appeared, bond strength also is decreased. From this experiment, we could know that color change due to chemical aging has the deep relationship with physical performance(bond strength) materials. further researches are needed.
