涂覆涂料前钢材表面处理 表面处理方法 手工和动力工具清理
Application Summary AI generated
This standard specifies hand- and power-tool cleaning methods for preparing steel surfaces before applying paints or related coatings. It is applied in manufacturing and industrial maintenance contexts, such as shipbuilding, bridge construction, and heavy machinery, where manual or mechanical tools are used to remove rust, mill scale, or old coatings from steel substrates. The standard ensures consistent surface cleanliness and roughness to improve coating adhesion and corrosion protection.
