Enameled wire is the main raw material for motors, electrical appliances and other products. It is used in most industrial fields of the national economy, with an annual domestic usage of nearly 2 million tons. As more and more scrapped enameled wires are scrapped, how to recycle them has become a major problem in the industry. The pollution caused by direct use is very serious. At present, thermal depainting has gradually become a mainstream process. However, there is no generally recognized technical standard for regenerating depainted copper wire, which restricts the healthy development of the industry. This standard is based on many years of practical experience of enterprises and combined with the technical trends of the industry. It stipulates the grades and classifications of recycled paint-removing copper wires, and clarifies indicators such as copper content, paint layer removal rate, surface carbon residue, and copper metal recovery rate. According to the specific requirements, detection methods for copper metal recovery rate and paint layer removal rate have been formulated, which basically meet the needs of downstream users.
