How to recycle cables wires


With the continuous improvement of living standards, waste wire and cable recycling is gradually developing, so what are the classification of waste wire and cable recycling? And how to recycle?
Recycling and classification of waste wires and cables:
1, the recovery of commonly used electrical accessories: cable terminal junction box, waste wire and cable treatment method connecting pipe and terminal, cable intermediate junction box, steel plate wiring groove, cable tray, etc.
2, recovery cable bridge: general industrial and mining enterprises indoor and outdoor overhead laying of power cables, waste wire and cable treatment method control cables, can also be used for telecommunications, radio and television departments in the indoor and outdoor erector.
3, according to the use can be divided into: bare wire, insulated wire, heat-resistant wire, power cable, control cable, waste wire and cable treatment method shielded wire, communication cable, radio frequency cable and so on.
4, recovery of cable intermediate joint: connecting the conductor, insulating shielding layer and protective layer of the cable and the cable, so that the cable line connection device, waste wire and cable treatment method is called the cable intermediate joint.

How to recycling waste wire and cable:
Recycling and treating waste wires and cables is mainly to obtain the non-ferrous copper in them. Therefore, for the waste wires and cables we recycle, how to deal with them, no matter which method is adopted, the ultimate purpose is to separate the copper from the wire skin. Therefore, we have the waste wire and cable disposal method of burning, peeling, crushing, freezing and so on.

1. Manual peeling method: this method uses artificial way to peel the wire and cable, its low efficiency and high cost, for some cable, square line is good to deal with some, if it is some automobile lines, network cables, household appliances dismantling line and other wool yarn miscellaneous lines, the effect is poor. With the development of current economy, the labor cost is getting higher and higher, and fewer and fewer waste wires and cables are treated in this way.
2. Incineration method: this method is a more traditional method, which uses the flammable nature of the wire cover to directly burn the waste wire and cable, and then recover the copper inside. In the process of burning copper wire, the copper wire is seriously oxidized, which reduces the recovery rate of non-ferrous metals. However, the burning of thread skin is more polluting to the environment. In the national strong grasp of environmental protection today, it is banned.
3. Mechanical peeling method: the method is used in the stripping machine equipment, which belongs to the semi-mechanized operation, need a manual, labor intensity is large. What’s more, the method is only applicable to some single-stranded square wires and cables. If we are recycling the automobile wire, home wire, cable, electronic wire and other raw materials, the use of stripping machine equipment is not suitable.

4. Mechanical crushing method: Was crushing and sorting methods used by this method, by crushing will scrap wire and cable peeling, after the use of air separation, electrostatic separation of copper and plastic separation, this method is widely applicable, can not only processing thick square wire, cable, can also processing lines to cars, motorcycles, electric wire, cable, communications lines, raw materials such as home appliances dismantling line, electronic line, At the same time, compared with mechanical peeling equipment, its output is higher, greatly reducing the intensity of manual work. Automatic cable granulator more environmental protection, no pollution, save labor costs.
5. Chemical method: When the word “chemistry” is mentioned, what we think of most is environmental protection. Indeed, the method uses a chemical solution, which is soaked to separate the wire from the copper. The problem is that the potions it produces are not easy to deal with and will cause greater environmental pollution, so the method is only in the experimental stage and has not really been put into civilian use.
6. Refrigeration method: it is relatively tall, the method is also put forward in the 1990s, the use of liquid nitrogen as a refrigerant, so that the waste wire and cable are frozen at ultra-low temperature and become brittle, and then after crushing and vibration, the plastic and copper separation. This method is costly, difficult to large-scale industrial operation, and has not been put into actual production.
