消光粉光泽和光泽的测定
Determination of Gloss and Gloss of Extinction Powder
光线投射到物体的表面会发生光线的反射，物体表面对光线的反射能力称为光泽。不同物体表面的光泽不一样，衡量物体表面对光线反射能力的大小，称为光泽度。光泽度用百分数表示。物体表面的光泽度越高，它反射光线的能力就越强，亮度也就越高。光泽度的大小通过光电光泽仪进行测定。根据光泽度的大小，可以将涂料分为亮光、亚光、无光等几种。
When light is projected onto the surface of an object, it will reflect light. The reflectivity of the surface of an object to light is called gloss. The gloss of different objects is different. It is called glossiness to measure the reflectivity of the object surface to light. Glossiness is expressed in percentage. The higher the glossiness of an object's surface, the stronger its ability to reflect light and the higher its brightness. The glossiness was measured by photoelectric glossometer. According to the glossiness, the coatings can be divided into bright, Matt and matt.
