AI Technical Summary
The existing single-layer enameled multi-color parallel line process is difficult to control the resistance difference within 3%, and due to the high friction coefficient and insufficient bonding force of the adhesive paint, the scratch resistance is poor.
By improving the wire drawing process, steam-heated copper wire is used to perform micro-stretching, reducing the resistance difference of single-layer enameled wire; at the same time, the composition of polyurethane paint is improved and modified vapor-phase silica is added to enhance the surface paint and the external adhesive paint. Binding power.
The resistance difference of single-layer enameled wire is controlled within 2%, and the scratch resistance of single-layer enameled multi-color parallel wire is significantly improved.
