Description

technical field [0001] The invention relates to the technical field of conductive agents, more specifically, it relates to a water-based inorganic conductive liquid and its preparation method and application. Background technique [0002] Electrostatic spraying is a spraying method that uses a high-voltage electrostatic electric field to make negatively charged paint particles move in the direction opposite to the electric field, and adsorb the paint particles on the surface of the workpiece. The premise of spraying powder coating is that the substrate has excellent electrical conductivity and can provide continuous electric field adsorption force for powder particles. However, the heat-sensitive insulating base material has poor conductivity, and it is necessary to solve its uniform adsorption capacity for charged powder. The traditional preheating process is to heat the plate, and the free water in the plate evaporates to the surface of the plate to form a water film, rely...
