标准摘要
[中文适用范围]： 该方法通常用于比较类似的颜料，例如测试颜料与商定的参考颜料。 颜料在指定条件下分阶段分散在商定的粘合剂体系中。 在每个阶段之后，取出一部分研磨料并制成组合物，将其施加到基材上并干燥或烘烤。 每个干燥薄膜的镜面光泽度按照 ISO 2813 中的描述进行测定。 光泽度值以图表形式绘制为分散阶段的函数（例如表示为时间、研磨机的转数）。 从该图中，可以确定获得一致的镜面反射值所需的色散功。 [外文原描述]： The method is of general use for comparing similar pigments, for example a test pigment against an agreed reference pigment. The pigment is dispersed in stages under specified conditions in an agreed binder system. After each stage, a portion of the mill base is taken and made into a composition that is applied to a substrate and dried or stoved. The specular gloss of each dried film is determined as described in ISO 2813. The gloss values are plotted graphically as a function of the dispersion stage (expressed for example as time, number of revolutions of a muller). From the graph, the dispersion work necessary to obtain an agreed specular reflection value is determined.
