Wide Application of Insulating Coatings for Electrical Steel
Electrical steel is a kind of metal material widely used in the manufacture of electrical equipment, which has excellent electrical conductivity, magnetic properties and corrosion resistance. However, because its surface is susceptible to oxidation, corrosion, etc., it is necessary to use insulating coatings for protection.
Electrical steel insulation coatingis a kind of coating specially used to improve the surface insulation performance of electrical steel, which is usually composed of polymers, solvents and additives. The coating has good high temperature resistance, abrasion resistance and corrosion resistance, and can effectively prolong the service life of electrical steel.
At present, the common electrical steel insulation coatings on the market include silicone insulation coatings, polyimide insulation coatings and epoxy resin insulation coatings. Among them, silicone insulation coating has excellent high temperature resistance and chemical stability, suitable for use in high temperature environment; Polyimide insulation coating has high dielectric strength and thermal resistance, and is suitable for manufacturing high voltage electrical equipment. Epoxy resin insulation coating has good mechanical properties and adhesion, suitable for the repair and maintenance of electrical equipment.
In addition to the traditional coatings, some new insulation coatings for electrical steel have been developed in recent years, such as nano-composite insulation coatings and inorganic ceramic insulation coatings. These new coatings have higher insulation properties and broader application prospects, and will become an important direction for the development of electrical steel insulation coatings in the future.
In short, electrical steel insulation coatings play an important role in the manufacture of electrical equipment, which can effectively improve the insulation performance and service life of electrical steel. With the continuous progress of science and technology and the continuous improvement of people's requirements for insulation performance, it is believed that the future electrical steel insulation coating will have a broader application prospect and development space.
