Different types of enameled wire, the curing process on the paint film requirements are also different, most enameled wire are coated with paint film, so that the paint film is fully cured. The polyimide enameled wire is completely different from the enameled wire.Today, xinyu brings you knowledge of enameled wire, such as Enameled Aluminum Wire, Enameled Copper Wire, etc.But if the paint film is fully baked every time during the curing process, the paint will separate between the paint layers and will not form a strong paint layer. The strength of the paint will be poor and the scratch resistance will be unacceptable. This is due to the complete curing of the polyacrylamideimide film after baking into a refractory material, coupled with its poor adhesion characteristics, resulting in film delamination phenomenon, in the scratch test, the film will form a scratch layer . The baking of the polyimide makes the film substantially solid but not enough. In some molecules of the film, there is still a small amount of unreacted reaction of the substrate. When the paint is completely baked, it is baked at a high temperature, the paint film is completely cured, and the whole is formed. More sturdy.
Most enameled wire can determine the degree of curing by the color of the paint film. However, due to the multiple baking of the enameled wire, the appearance is not comprehensive. When the internal curing is not sufficient, the external curing is sufficient and the enameled wire is good in color, but the peeling property is poor, and the heat aging test may cause large peeling of the film housing.
In the curing reaction, the density or humidity of the solvent gas in the gas mainly affects the conjunctiva reaction, and the strength of the enameled film decreases, which affects the scratch resistance.
Xinyu is always committed to producing various specifications (0.18~6.50mm) and temperature levels (130~220C) of enameled aluminum wire, enameled copper wire, enameled copper clad aluminum wire(ECCA). Under the the guidance of “Quality First, Customer Uppermost”, Xinyu has made great efforts in technological innovation and market development. After years of development, Xinyu brand becomes one of the best-known manufacturers in the field of enameled wire both in China and worldwide.
