Talk about the reason why the enamelled wire is not oxidized

Enamelled wire can avoid oxidation, mainly based on the following key factors:

First, the insulating coating on the surface of the enameled wire plays a key role in isolation. This paint can effectively prevent oxygen from coming into direct contact with the wire, thus reducing the possibility of oxidation reactions.

For example, common polyester paint, polyester imide paint, etc., the dense coating they form is like a solid barrier to keep oxygen out.

Secondly, the paint layer itself has good chemical stability. This means that the coating material does not react chemically with oxygen easily, thus not providing conditions for the oxidation process.

In addition, the enamelled wire usually goes through strict treatment and process control in the production process. For example, the cleaning and pretreatment of the wire surface can remove impurities and pollutants that may lead to oxidation, providing a good basis for subsequent painting and anti-oxidation.

In addition, when storing and using enamelled wire, if the environmental conditions are reasonably controlled, such as keeping dry and avoiding adverse factors such as high temperature and humidity, it also helps to reduce the risk of oxidation.

In short, the enamel wire is not oxidized is the result of many factors, including the isolation and stability of the paint layer, the optimization of the production process and the control of environmental conditions.

The main reason the enameled wire will not oxidize is that the wire surface is covered with a coat of paint. No matter how the external environment changes, the coating will play its own characteristics, such as some antioxidant functions. The general copper material is oxidized because its surface will be eroded by air, water, oil and other dirt, resulting in copper oxide and cuprous oxide, and then show the phenomenon of gray and dark red.

Enamelled wire is mainly composed of a conductor and an insulating layer. Its bare conductor wire is softened by annealing, then painted and baked several times. It can be used in all areas of life, such as various motors, transformers, rectifiers, voice coils, electromagnetic induction coils, etc. Enamelled wire, there are many kinds, such as pure copper enamelled wire, copper enamelled aluminum wire, aluminum enamelled wire and so on.

Pure copper enamelled wire as a traditional type of enamelled wire, pure copper, enamelled wire is widely used, generally has the advantages of easy welding and stable performance.

Copper coated aluminum wire as a substitute for pure copper coated wire, enameled wire, copper coated aluminum enameled wire has excellent high frequency transmission performance and can be used for various high frequency electromagnetic induction coils. At the same time, its density is small, and the unit product weight is 40% higher than that of copper wire to save less, which can greatly save the cost of production materials.

Aluminum enamelled wire has a lower density than copper coated aluminum, and the unit product weight is less than that of copper wire, which is 60% higher, saving the production material cost.
