Application introduction of magnet wire coating products

At present, the application of magnet wire coating products has greatly increased the amount of magnet wire with the acceleration of my country's modern industrial construction and the rapid growth of export products. Enameled wire and magnet wire mainly use insulating electrostatic powder coatings. The insulating oxide film magnet wire treated with concentrated sulfuric acid of metal aluminum wire can also be applied to the enameled wire coated with insulating varnish. The following is an introduction to the application of magnet wire coating products: Because the coating thickness of general powder coatings is suitable for round wires with a diameter of more than 1.6mm or flat wires with a width × thickness of 1.6mm × 1.6mm or more, coating Insulation coatings with a film thickness of 40 μm or more cannot be used for coatings requiring thin coatings. If the ultra-thin powder coating is used, the thickness of 20-40 μm can be achieved, but due to the high cost of coating processing and the difficulty of coating, it cannot be widely used. When the thickness of the coating film is too thick, the flexibility and other functions of the coating film will be reduced, and it is not suitable for products with too large bending angle of the metal wire. Due to the limitation of film thickness, too thin metal wires are not suitable for powder coating technology.
