Tianjin waste wire and cable recycling method and treatment method

Tianjin scrap wire and cable recyclingMethod and treatment method

Waste cable recycling classification

1. Recycle common electrical accessories: cable terminal junction box, connecting pipe and terminal, cable intermediate junction box, steel plate junction box slot, cable bridge, etc。

2, recovery cable bridge: general industrial and mining enterprises in indoor and outdoor overhead laying power cables,。Disposal method of abandoned wire and cable control cable, can also be used for telecommunications, radio and television departments in indoor and outdoor erection。

3, can be divided into bare wire, insulated wire, hot wire, power cable, control cable, waste wire and cable treatment shielding line, communication cable, radio frequency cable, etc。

4. Regenerative cable intermediate connector: a device for connecting cables and lines with conductors, insulating shielding layers and protective layers。The disposal method of abandoned wire and cable is called cable intermediate connector;
Disposal method of waste cable
1, manual peeling method: This method uses manual peeling, low efficiency, high cost, workers operating environment is poor;

2, incineration method: Incineration method is a traditional method, the plastic shell of the waste cable will be burned to recover the copper, but the smoke pollution is extremely serious。At the same time, the copper wire surface is severely oxidized during the incineration process, reducing the metal recovery rate。This method has been strictly banned by governments。

3, mechanical peeling method: cable peeling machine processing, waste wire and cable still need manual operation。This method is semi-mechanized, with high labor intensity and low efficiency, and is only suitable for the processing of coarse diameter cables。

4, chemical method: chemical treatment of waste cable technology is proposed in the 1990s。One of the disadvantages of this method is that the waste liquid produced cannot be treated and has a great impact on the environment, so it is rarely used。

5, freezing method: The disposal method of abandoned wire and cable is also proposed in the 1990s。Liquid nitrogen is used as the refrigerant to make the waste cable brittle at very low temperatures, and then the plastic skin is separated from the copper wire by extrusion and vibration。However, the disadvantage of this method is that it is expensive and difficult to carry out industrial production。
