Composite Insulation Coating Enameled Wire For Chemical Engineering
Product standard of enamelled round wire: GB6109-90 series standards
Polyurethane coating wire paint was developed by Bayer in 1937. It has the characteristics of direct welding, high frequency resistance and dyeing, so it has been widely used in the fields of electronics and electrical appliances. At present, foreign countries pay great attention to the improvement of heat resistance grade of polyurethane coating line without affecting its direct welding performance
Nickel has high chemical stability and good corrosion resistance in many media.
Its standard electrode position is -0.25V, which is positive than iron and negative than copper.
Nickel exhibits good corrosion resistance in the absence of dissolved oxygen in dilute non-oxidized properties (e.g., HCU, H2SO4), especially in neutral and alkaline solutions.This is because nickel has the ability to passivate, forming a dense protective film on the surface, which prevents nickel from further oxidation.
These enameled resistance wires have been broadly used for standard resistors, automobile parts, winding resistors, etc. using the insulation processing best suited for these applications, taking full advantage of the distinctive features of enamel coating.
Furthermore, we will carry out enamel coating insulation of precious metal wire such as silver and platinum wire upon order. Please make use of this production-on-order.
