Abstract
The invention discloses a production process of a copper plating wire. The production process comprises the steps of degreasing an aluminum wire; performing acid cleaning; performing ultrasonic cleaning and washing; performing passivation; plating a nickel alloy layer; performing cleaning activation; plating copper; performing cleaning passivation; plating tin, instantly placing the copper-clad aluminum wire undergoing cleaning passivation in tin plating liquid of 20-40 DEG C, controlling the transmission speed at 2-5m/s, and controlling current density at 5-15a/dm2; performing washing; and drying, winding and packaging the copper plating wire. The production process is reasonable, plated layers are good in uniform adhesion, a tin plating layer has extremely good oxidation resistance, using cost is low, and resources are saved.
Description
Technical field
The invention belongs to the electric wire processing technique field, be specifically related to a kind of copper facing electric wire production technology.
Background technology
Most of pure copper wire that uses in present electric wire or cable, pure copper wire conducts electricity very well, but the high resource of copper price needs a large amount of import use costs high less, progressively adopted now aluminum steel to replace pure copper wire, but the large poor electric conductivity of aluminum steel resistance, we need at present a kind of instead of wireline with the good conductivity of copper cash and aluminum steel economy with and production technology.
Summary of the invention
The object of the present invention is to provide a kind of technique reasonable, coating is even, the copper facing electric wire production technology that the use cost that conducts electricity very well is low.
Technical solution of the present invention is:
A kind of copper facing electric wire production technology is characterized in that: comprise the following steps 1, with the aluminum steel degreasing degreasing, 2, pickling, 3, with Ultrasonic Cleaning and washing, 4, passivation, 5, nickel plating alloy layer, 6, clean activation, 7, copper facing, 8, Cleaning and Passivation, 9 is zinc-plated, soon the copper-clad aluminum conductor after Cleaning and Passivation is put into temperature immediately at 20 ℃～40 ℃ tin plating electrolytes, and transmission speed is controlled at 2 ~ 5m/s, and current density is controlled at 5～15a/dm
2, 10, washing, 11, the dry packing of reeling.
Technique of the present invention is reasonable, and the even tack of coating is good, and tin coating has that good oxidation proof properties@and use cost are low to economize on resources.
