Scope

Scope: This document applies to recycled de-painted copper wires produced from waste enameled wires. Waste enameled wires mainly come from scrapped mechanical and electrical products and unqualified enameled wires or scrap materials generated during the production process of enameled wire manufacturers. Main technical content: Enameled wires are the main raw materials for motors, electrical appliances and other products, and are applied in most industrial fields of the national economy. The annual domestic consumption volume is nearly 2 million tons. With an increasing number of scrapped enameled wires, how to recycle them has become a major challenge for the industry. Direct utilization of scrapped enameled wires causes serious pollution. At present, pyrolytic de-painting has gradually become the mainstream process, but there is still no widely recognized technical standard for recycled de-painted copper wires, which restricts the healthy development of the industry. Based on the company's years of practical experience and combined with the technical trends of the industry, this standard specifies the grades and classification of recycled de-painted copper wires, clarifies the specific requirements of indicators such as copper content, paint removal rate, surface residual carbon content, and copper metal recovery rate, and formulates the testing methods for copper metal recovery rate and paint removal rate, which basically meets the various needs of downstream users.
