The standard describes the typical process of high voltage airless spraying, including the selection of lame plating equipment, operating parameters, lame plating technology and maintenance. It provides systematic guidance for high voltage airless spraying technology to ensure coating mass and lame plating effect. Proposed by the National Metal and Non-metallic Coating Standardization Technical Committee and drafted by Wuhan Institute of Material Protection, it is suitable for high voltage airless spraying operations in various industrial painting projects.
