Problems solved by technology

[0003] At present, most of the traditional grounding materials in my country are made of steel (galvanized flat steel), but the corrosion resistance of steel is poor, and the corrosion problem of the grounding device is constantly exposed. It is necessary to invest a lot of money and manpower to transform the galvanized steel grounding device every year.

Abstract

The invention relates to a copper-plated steel wire and a production method thereof. The production method for the copper-plated steel wire comprises the following steps of pre-treating low-carbon steel, carrying out copper pre-plating, carrying out copper preliminary activating after carrying out water washing, carrying out acid thick copper plating and then carrying out post-treatment so as to obtain the copper-plated steel wire. According to the copper-plated steel wire and the production method thereof, an existing process for a copper-plated steel wire is improved, and therefore the working procedures taking the three modes, namely oil removing-copper pre-plating-acid thick copper plating as the principal things are determined; an HEDP solution is adopted for activating and pre-plating a copper layer, and therefore the copper-steel binding force can be greatly enhanced; and meanwhile, high-temperature, high-current-density and high-speed air agitation is adopted for electroplating, and a compact and smooth coating can be quickly achieved by means of the synergistic effect of multiple aspects.

Description

technical field [0001] The invention relates to a copper-plated steel wire and a production method thereof, belonging to the technical field of electroplating. Background technique [0002] With the continuous advancement of information technology, the demand for professional and effective lightning protection technology in various fields and industries is particularly urgent; a long-term, reliable and stable grounding system is the fundamental guarantee for maintaining stable operation of equipment and ensuring the safety of equipment and personnel. The key to long-term safe and reliable operation of the system lies in the correct selection of appropriate grounding materials and reliable connections. [0003] At present, most of the traditional grounding materials in my country are made of steel (galvanized flat steel), but the corrosion resistance of steel is poor, and the corrosion problem of the grounding device is constantly exposed. It is necessary to invest a lot of m...
