BS EN ISO 23900-2:2018规定了一种测定测试颜料颜色特性的方法 相对于一个标准，DHPVC-P颜料分散的难易程度取决于颜色的差异 增塑聚氯乙烯在不同条件下分散着色剂的强度 （PVC-P）化合物。该方法适用于有机和无机黑色和彩色颜料以及颜料 准备工作。以这种方式确定的分散易度仅对分散设备有效，即分散 使用的条件和分散介质。使用不同于规定的试验条件 可能会产生不同的结果；这既适用于绝对量值，也适用于值之间的关系 各种颜料易于分散。下标DHPVC- 因此，P被用来表示 根据ISO 23900本部分规定获得的值。ISO 23900本部分的原则也可通过参考用于常规质量控制目的 对于在130°C下研磨的板材产生的光度数据，出于质量控制目的 相关方可就颜料与TiO2的比例达成一致。有机颜料的比例为1:10 建议无机颜料的0.2至0.5:1为方便且广泛使用的标准比例。交叉引用:ISO 787-24:1985ISO 15528ISO 18314-1EN 12877-1EN 12877-4购买本文件时提供的所有当前修订版均包含在购买本文件中。

BS EN ISO 23900-2:2018 specifies a method of determining the colouristic properties of a test pigment relative to a standard, and the ease of dispersion DHPVC-P of pigments from the differences in colour strength on dispersing colouring materials under various conditions in plasticized polyvinyl chloride (PVC-P) compounds.The method is appropriate for use with organic and inorganic black and colour pigments and for pigment preparations.The ease of dispersion determined in this way is valid only for the dispersion equipment, dispersion conditions and dispersion medium being used. The use of test conditions differing from those specified may give different results; this applies both to the absolute magnitude and to the relation between values of the ease of dispersion of various pigments. The subscript DHPVC-P is therefore used to designate the value obtained as specified in this part of ISO 23900.The principle of this part of ISO 23900 may also be used for routine quality control purposes by reference to the photometric data generated from the sheets milled at 130 °C. For quality control purposes, the ratio of pigment to TiO2 may be agreed between the interested parties. Ratios of 1:10 for organic pigments and 0,2 to 0,5:1 for inorganic pigments are suggested as convenient and widely used standard ratios.Cross References:ISO 787-24:1985ISO 15528ISO 18314-1EN 12877-1EN 12877-4All current amendments available at time of purchase are included with the purchase of this document.
