标准摘要
[中文适用范围]: 本文件规定了一种通过筛分分析测定涂层粉末粒度分布的方法。 最大粒度小于 100 µm 的粒度分布通过激光衍射 (ISO 8130-13) 测定。 该方法尤其用于测定过大材料或是否存在污染物,并且可以用作质量控制程序(“通过”/“不通过”测试),通过检查单个筛子上的保留量。 以下粒度是涂层粉末的典型粒度,但粒度会根据应用而有所不同: — 薄膜技术:1 µm 至 63 µm; — 静电喷涂:10 µm 至 200 µm; — 流化床法:100 µm 及以上。 注:网眼尺寸小于 32 µm 的筛子不实用,在使用过程中容易变盲。 [外文原描述]: This document specifies a method for the determination of the particle size distribution of coating powders by sieve analysis. Particle size distributions with a maximum of less than 100 µm is determined by laser diffraction, ISO 8130‑13. This method is used especially for determining the oversize material or for the presence of contamination and can be used as a quality control procedure ("go"/"no go" test) by checking the amount retained on a single sieve. The following particle sizes are typical for coating powders, however the particle size can deviate depending on the application: — thin-film technology: 1 µm to 63 µm; — electrostatic coating: 10 µm to 200 µm; — fluidizing-bed method: 100 µm and above. NOTE Sieves with a mesh size smaller than 32 µm are not practical and are likely to become blind during use.
