How to remove the outer skin of the wire

Methods to remove the outer skin of the wire:

1, manual peeling method, the method uses manual peeling, low efficiency and high cost.

2, incineration method, incineration is a traditional method to make the plastic skin of the waste cable burning, and then recover the copper in it, but the smoke generated by the pollution is extremely serious, at the same time, in the incineration process of the surface of the copper wire is seriously oxidized, reducing the rate of recovery of the metal, the method has been strictly prohibited by governments.

3, mechanical stripping method, the use of cable stripping machine for processing, the method still requires manual operation, is semi-mechanized, labor-intensive, low efficiency, and only applies to deal with thick diameter cable.

4, chemical method, chemical treatment of waste cable technology was proposed in the 1990s.

5, the freezing method, the method was proposed in the 1990s, the use of liquid nitrogen as a refrigerant, so that the waste cable at very low temperatures to become brittle, and then after the crushing and vibration, so that the plastic skin and copper segments of the separation, but the disadvantage of this method is the high cost, it is difficult to carry out industrialized production.
