The use and characteristics of conventional insulating varnishes

insulation materials classification many, there are insulation board, insulated wire, as well as insulating paint, are some widely used insulating materials. Since the use of different, then the use of insulating paint varieties are different, what are the more commonly used types?
Most of the insulating paint is composed of paint base, solvent or thinner and auxiliary materials and other components, and can be divided into impregnated paint, enameled wire paint, covering paint, silicon steel paint, anti-corona paint and other varieties. Which impregnated insulating paint can also be divided into solvent paint and solvent-free paint two categories, mainly used in dipping motor, electrical coil and so on.
 Enameled wire insulation paint, of course, is a special enameled wire core coated insulating material, this insulating paint has a good coating, making the coating evenly, and the film adhesion, smooth and soft surface toughness; In addition, but also have a certain Wear resistance and elasticity, electrical performance, heat resistance, solvent resistance, no corrosion on the conductor and other characteristics.
Covered with heat resistant tape paint is used to coat the impregnated coil and insulation components of the material, in its surface to form a uniform thickness of the insulation protection layer to prevent the equipment insulation by mechanical damage and the atmosphere, the erosion of chemicals, improve surface insulation strength.
In contrast, silicon steel insulation paint is mainly used for coating silicon steel sheet, in order to reduce the core of the eddy current loss, and enhance corrosion resistance. However, it should be noted that the silicon steel insulation coating after the need for high temperature drying, in order to play a good feature.
The remaining anti-corona insulating paint is a kind of insulating varnish and non-metallic conductor powder mixed with insulating material, mainly for high-voltage coil, in order to play a good use requirements, requiring such insulation paint surface resistivity and stability, Strong adhesion, good wear resistance, fast drying, storage and so on.
