1. Manual peeling method: manual peeling is adopted in this method with low efficiency and high cost, and workers' operating environment is poor;
2. Incineration method: incineration method is a traditional method to make the plastic skin of waste cable burn, and then recover the copper, but the smoke pollution is extremely serious. Disposal method of waste wire and cable
3. Mechanical peeling method: cable peeling machine is adopted for processing, and waste wire and cable treatment method still requires manual operation, which is semi-mechanized with high labor intensity and low efficiency, and only suitable for processing coarse diameter cable;
4. Chemical method: the technology of chemical treatment of waste wire and cable was put forward in the 1990s. The treatment method of waste wire and cable has been studied in some countries, including China during the eighth five-year plan period. One of the biggest disadvantages of this method is that the waste liquid produced cannot be treated, which has a great impact on the environment, so it is seldom used.
5. Frozen method: scrap wire and cable processing method of the method is also put forward in the ninety s, using liquid nitrogen for refrigerants, waste cable brittle at low temperatures, and then after crushing and vibration, make plastic skin from copper wire section, during the period of "five-year" also once project research in China, scrap wire and cable processing way but the disadvantage is high cost, this method to industrialized production.
