标准范围

本文件规定了通过筛分分析测定涂层粉末粒度分布的方法。最大粒径小于100μm的粒径分布由激光衍射确定，ISO 8130-13。该方法特别用于确定超大材料或是否存在污染，并可通过检查单个筛子上的残留量作为质量控制程序（“go”/“no go”测试）。以下粒度是涂层粉末的典型粒度，但粒度可能会因应用而有所不同:-薄膜技术:1μm至63μm；-静电涂层:10μm至200μm；-流化床法:100μm及以上。注:筛孔尺寸小于32μm的筛子不实用，在使用过程中可能会变盲。

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.
