How to separate copper and plastic from scrap copper wire?
Scrap copper wire is made of copper and plastic, which can be separated and reproduced new products. The effective separation of copper and plastic has always been a top priority in the later stage of the scrap copper wire recovery. At present, there are three main separation methods to separate copper and plastic from scrap copper wire: fire burning, chemical dissolution and dry physical separation. Fire burning:
Fire burning is a method for easily disposal for scrap copper wire, which takes advantage of the flammability of scrap copper wire. Through burning, the plastic of the outer layer of scrap copper wire will be melted, and the remaining metal is the non-flammable metal - copper.
Fire burning can separate copper and plastic from scrap copper wire with a simple and fast way. However, during burning, the melted plastic will stick to copper, which will cause low separation rate and recovery rate of copper. Besides, it will produce a large amount of gas, which has severe pollution to environment.
Chemical dissolution:
Chemical dissolution is chemical method, which will use chemical dissolution to process scrap copper wire to separate copper and plastic. Immerse the scrap copper wire in water with chemical solvent, and just left for 1-2 hours, the copper will be extracted naturally.
Just like fire burning, this method can also separate copper from plastic fast and simple. But the recovery rate is relatively inefficient, and to some extent, the quality of copper will also be affected due to the chemical solvent, which won't be sold a good price in metal trading market. In addition, the used water with chemical solvent is usually dumped directly, which will cause pollution to soil and water.
Dry physical separation:
Dry physical separation usually refers to process scrap copper wire by using scrap copper wire recycling machine, which is an environmental friendly and high efficient way to separate copper
and plastic from scrap copper wire. The whole scrap cable wire recycling machine includes crushing, air separation and electrostatic separation.
First, the scrap cable wires is pressed into small pieces so that it can be separated in the air separator because of the difference in gravity between copper and plastic. And if the raw material has very thin wires, the separation rate may not be so ideal, so electrostatic separation is required. Electrostatic separator can separate fine copper from plastic according to their different conductivity.
The working process of scrap copper wire recycling machine uses no water, fire, or chemical solvent, and the dust removal system ensures that no dust is flying during operation, thus it won't lead to any pollution to environment. Moreover, the separated copper and plastic have high quality, which have a considerable price.
