The Production Process Of Enameled Copper Wire Is A Complicated Process

Today, I'd like to introduce the production process of Enameled Copper Wire. The precondition is that the viscosity of paint, solid content, surface tension and contact angle are internal factors, while temperature and speed are external factors.

In the production process of enameled copper wire, the enamel liquid of enameled wire changes into a solid paint film after coating and baking. Theoretically, the lacquer-based polymer changes from a solution state to a polymer body, which is a complex physical and chemical process. Related to some basic concepts, especially polymer solution and related surface tension phenomena, evaporation of solvent and chemical reaction of polymer are closely related to the production process of enameled copper wire.

The production process of enameled copper wire is a process of painting enameled wires on metal wires to form a uniform paint film. Why can the paint be coated on the wire to form a uniform and smooth paint film? This problem involves liquid surface tension, wetting angle, and other characteristic parameters as well as solvent evaporation characteristics. The expression of surface tension is that the surface area of liquid is contracted to the minimum by physical force. Because the surface area of the ball is the smallest in the geometry of the same volume, if the liquid is not affected by any other force, it will become annular under the action of surface tension.

Pay-off Tension Of Copper Enameled Wire Should Be Uniform

In the electromagnetic wire manufacturers, we can see that the manufacturing process of copper enameled wire mainly includes: paying-off, annealing, painting, baking, cooling, lubrication, and winding up. On a normal operation enameled wire machine, most of the energy and physical strength of the operators are consumed in the paying-off part. Replacing the paying-off disc causes the operators to pay a lot of labor. During wire replacement, the joints are prone to quality problems and running faults. The effective method is large-capacity paying-off.

The key to the copper enameled wire is to control the tension. When the tension is high, it not only thins the conductor, making the surface of the conductor lose its brightness, but also affects many properties of the copper enameled wire. From the outside, the copper enameled wire coated by the thinned wire has poor luster. From the performance point of view, the elongation, resilience, flexibility and thermal shock of copper enameled wire are all affected. The pay-off tension is too small, and the thread is easy to jump, causing the problem of parallel thread or thread touching the furnace exit. When unreeling, it is most afraid of uneven tension in half a turn, which not only makes the wires loose and broken, and the wires are thinned one by one, but also causes big jump inside the oven, causing parallel and collision faults. Therefore, the unreeling tension should be uniform and appropriate.
