This article discusses how to apply the liquid crystal film to the surface of the product in the liquid crystal inspection electrostatic method. The sketch of high voltage electrostatic generator and electrostatic spray gun is given, and the technical factors that influence the quality of spray are discussed and discussed. The formulation of the liquid crystal solution for electrostatic spraying and the method for adjusting the conductivity of the formulation are provided. Finally, an example of a specific description of the electrostatic spraying process.
