Introduction
Now environmental requirements are becoming more and more stringent. If factories do not properly process their waste, it will increase the burden of garbage disposal. Plastics, wires, and cables are among the most common electrical equipment at the end of their life.
Has anyone ever thought about how to deal with old, discarded wires and cables? Today, Wanrooetech Machine will explain several common recycling methods.
Common Recycling and Processing Methods for Used Cables
1. Manual Peeling Method
This method mainly uses manual peeling. It has low efficiency, high cost, a poor working environment for workers, and high health risks.
2. Incineration Method
Incineration is a traditional method that burns the plastic insulation off waste cables and then recovers the copper. However, the flue gas pollution is very serious.
During the incineration process, the surface of the copper wire undergoes severe oxidation, reducing the metal recovery rate. Currently, this method has been strictly prohibited by governments.
3. Mechanical Separation
Mechanical separation refers to the use of crushing and sorting methods to separate copper from waste copper cables. A copper granulator machine is suitable for processing different sizes of waste copper cables.
Through dry crushing, waste copper cables are broken into a copper-plastic mixture. Then, using air specific gravity and high-voltage electrostatic separation technology, copper and plastic are separated. The copper-plastic separation purity can reach 99%.
This is a superior recycling method for waste copper cables.
4. Chemical Method
Chemical treatment technology for waste cables was proposed in the 1990s. This method for waste wire and cable treatment has been studied in some countries.
The biggest disadvantage of this method is that the waste liquid produced cannot be properly treated, which has a significant impact on the environment. Therefore, it is rarely used.
5. Freezing Method
The freezing method for processing waste cables was proposed in the 1990s. Using liquid nitrogen as a refrigerant, waste cables become brittle at low temperatures. After crushing and vibration, the plastic insulation and copper wire are separated.
This is a very effective method for processing scrap wire and cable, but due to its high cost, it is difficult to popularize in industrial production.
Important Note
The separated copper must be returned to a copper recycling company for recycling and is prohibited from entering the market through reprocessing.
