乙丙橡胶色度检测的影响因素分析

Analysis on influencing factors of color detection of ethylene propylene rubber

采用不同的操作条件,分析样品厚度、背景、入射光模式、样品透明度等因素对测定乙丙橡胶色度值的影响。结果表明,实验测得乙丙橡胶黄色指数(YI)和在日光照射下观察到的黄色程度能较好地吻合,因而能用于评价乙丙橡胶外观色度。

the yellow index(YI)of ethylene propylene rubber measured by experiment is in good agreement with the Yellow degree observed under sunlight,so it can be used to evaluate the appearance chromaticity of ethylene propylene rubber.Under different operating conditions,the effects of sample thickness,background,incident light mode and sample transparency on the chromaticity value of ethylene propylene rubber were analyzed.
