JB/T 5260-1991 "Guidelines for the Painting Process of Silicon Steel Sheets" is a mechanical industry standard, which stipulates the technical requirements and operating specifications for the painting process of silicon steel sheets. The content covers the pretreatment of painting (silicon steel sheet surface cleaning, degreasing), the selection of insulating paint (film adhesion, heat resistance and other performance indicators), the coating process parameters (paint concentration, coating speed, drying temperature and time), the operation process (paint method selection, coating thickness control) and mass inspection (film Appearance, insulation resistance test). The standard is applicable to the coating process of silicon steel sheet insulation coating, which aims to improve the insulation performance and interlayer adhesion of silicon steel sheet through the standardized process, reduce eddy current loss, provide technical guidance for the core manufacturing of electrical equipment such as motors and transformers, and ensure the energy efficiency and stability of electromagnetic devices.
