Embodiment 1

[0031] This example provides a method for regenerating copper rods from scrap copper wires, said method comprising the steps of:

[0032] (1) Use mechanical treatment to separate the waste copper wire and the plastic sheath to peel the waste copper wire, and then cut it into scrap copper particles of about 2.5mm;

[0033] (2) Polish the scrap copper particles prepared in step (1) with a polishing composition for 5 seconds. After polishing, put the scrap copper particles into clear water for 15 seconds of ultrasonic vibration, filter out the scrap copper particles, and then place them in a drying oven heated to 80°C, dried for 2 hours, and then stored in a closed oxygen-free environment; wherein, the polishing composition includes the first polishing agent, the second polishing agent and water in mass percentage, the first Polishing agent: 30% phytic acid, 20% hydroxyethylidene diphosphonic acid, 30% citric acid, 15% benzotriazole and polyethylene glycol 200 (purchased from Xi’...

Abstract

The invention discloses a method for regenerating a copper rod from a waste copper wire and a regenerated copper rod. The method comprises: (1) peeling the waste copper wire and making waste copper particles; (2) using a polishing composition to make The waste copper particles are polished, filtered and dried; the polishing composition includes a first polishing agent, a second polishing agent and water, and the components of the first polishing agent include a copper ion chelating agent, an organic acid, a brightening agent and a dispersing agent. The second polishing agent is sulfuric acid; (3) the treated waste copper particles are heated to the first temperature, kept warm, and hot-pressed into copper billets, and then the copper billets are heated to the second temperature, kept warm, and hot-extruded into copper rods; the first The temperature is 800-850°C, and the second temperature is increased by 50-100°C relative to the first temperature; and the regenerated copper rod made by the above method avoids problems such as low recovery rate, high cost, environmental pollution and the like of existing recycling methods , the low-oxygen copper rod was obtained in a green and environmentally friendly manner.

Description

technical field [0001] The invention belongs to the technical field of regeneration of pure copper waste, and in particular relates to a method for regenerating copper rods from waste copper wires and the regenerated copper rods. Background technique [0002] Copper has excellent electrical conductivity, thermal conductivity and ductility, so it is widely used in various fields such as electricity, electronics, air conditioning, transportation, construction, etc. Especially with the rapid development of the power industry, the demand for copper wires is increasing day by day. However, with the wide application of copper, there are a large number of waste copper wires in the market that need to be recycled due to process debugging, product replacement, scrapping and other reasons in the copper wire production process. According to different product forms, waste copper wire mainly includes waste bare wire, waste wire and cable with skin, and waste enameled wire. Moreover, the...
