Gloss measurement of surface

This paper introduces the measurement method of non-metallic materials floating on the surface. Focusing on the basis of 20°, 45°, 60°, 85° specular gloss methods, discuss their measurement principles, methods, accuracy and correction. And taking the SS-75 Youdian Yuze meter formed by the 45° specular gloss method as an example, the application of this method to the gloss measurement on the surface of the building material "Sanshi" is illustrated.
