标准范围

ISO 2884的本部分是涉及色漆、清漆和相关材料的取样和测试的系列之一产品。它补充了ISO 2431:1993《色漆和清漆-使用流动杯测定流动时间》。它规定了在测定色漆、清漆和涂料的动态粘度时应遵循的一般程序相关产品的剪切速率在9 000 s之间？1和12000美元？1.获得的值提供了有关材料对刷洗、喷涂和滚筒的阻力的信息在使用过程中进行涂层。ISO 2884本部分规定的方法适用于所有色漆和清漆，无论其在任何情况下是否为牛顿型行为与否。含有大颗粒分散体的材料会产生虚假结果。

This part of ISO 2884 is one of a series dealing with the sampling and testing of paints, varnishes and relatedproducts.It supplements ISO 2431:1993, Paints and varnishes — Determination of flow time by use of flow cups.It specifies the general procedure to be followed in determining the dynamic viscosity of paints, varnishes andrelated products at a rate of shear between 9 000 s?1 and 12 000 s?1.The value obtained gives information about the resistance offered by the material to brushing, spraying and rollercoating during application.The method specified in this part of ISO 2884 is suitable for all paints and varnishes whether they are Newtonian inbehaviour or not. Materials containing dispersions of large particles will produce spurious results.
