标准范围

ISO 8504的本部分描述了在涂覆油漆和相关产品之前，钢表面处理的喷砂清理方法。它还包含关于各个方法的有效性及其应用领域的信息。ISO 8504适用于新的和腐蚀的钢表面，以及未涂覆或之前已涂覆油漆和相关产品的钢表面。有关限制，请参见注释2。注1:这些方法基本上适用于热轧钢，以去除轧屑、锈迹等，但也可用于足够厚度的冷轧钢，以承受磨料冲击造成的变形。注2:为了补充ISO 8504的这一部分，买方的采购文件中应包括几个项目。涂层前表面处理应考虑的项目包括边缘打磨、油脂和油的去除、焊缝气孔、焊接飞溅物的去除、毛刺和其他锐边的去除、焊缝的打磨、，填充凹坑和其他表面缺陷，这些缺陷可能导致涂层系统过早失效（更多信息见ISO 8501-3），并去除水溶性污染物。

This part of ISO 8504 describes abrasive blast-cleaning methods for the preparation of steel surfaces before coating with paints and related products. It also contains information on the effectiveness of the individual methods and their fields of application.ISO 8504 is applicable to new and corroded steel surfaces and to steel surfaces that are uncoated or have been previously coated with paints and related products. For limitations, see note 2.NOTE 1 These methods are essentially intended for hot-rolled steel to remove mill scale, rust, etc., but could also be used for cold-rolled steel of sufficient thickness to withstand the deformation caused by the impact of abrasive.NOTE 2 There are several items that should be included in the purchaser's procurement documents to supplement this part of ISO 8504. Items that should be considered as a part of surface preparation before coating are edge grinding, removal of grease and oil, porosity of welds, removal of weld spatter, removal of burrs and other sharp edges, grinding of welds, filling of pits and other surface imperfections that may cause premature failure of the coating system (see ISO 8501-3 for more information) and the removal of water-soluble contaminants.
