标准摘要
[中文适用范围]: 涉及通过 ISO 8780 中描述的方法之一分散的有色颜料。 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。 其原理在于在指定条件下将颜料分阶段分散在商定的粘合剂体系中。 在每个分散阶段之后,取出一部分研磨料并分别与白色颜料混合以形成还原浆料。 每种还原浆料的着色强度按照 ISO 787-24 中的描述进行测定。 计算两个分散阶段之间着色强度的百分比增加,以评估颜料分散性的容易程度。 [外文原描述]: Relates to coloured pigments which have been dispersed by one of the methods described in ISO 8780. The method is of general use for comparing similar pigments, for example a test pigment against an agreed reference pigment. The principle consists in dispersing the pigment in stages under specified conditions in an agreed binder system. After each dispersion stage, a portion of the mill base is taken and mixed separately with a white pigment to form a reduced paste. The tinting strength of each reduced paste is determined as described in ISO 787-24. The percentage increase in tinting strength between two dispersion stages is calculated in order to assess the ease of dispersibility of the pigment.
