The standard is JB/T 7504-1994 "Technical Conditions for Electrostatic Spraying Equipment", which stipulates the technical requirements of electrostatic spraying equipment. The content covers the electrostatic performance of the equipment (Electric Field Strength, Charge Density), lame plating efficiency (Coating adhesion rate, atomization effect), structural design (insulation protection, grounding requirements), safety control (overload protection, explosion-proof measures) and environmental adaptability (temperature and humidity tolerance, anti-interference ability), etc., and clarifies the performance indicators and test methods. It is suitable for lame plating equipment using the principle of electrostatic adsorption, providing technical specifications for its design, manufacturing and inspection to ensure efficient and uniform coating deposition in industrial painting, and at the same time ensure the safety and stability of equipment operation.
