Copper Wire Recycling: Small but Promising Industry

As we all know, electrical industry is the main sector of copper consumption. Construction, Manufacturing industry and transportation also need great amounts of copper.  Besides, copper is widely used in communication equipment like mobile phone, TV, communication satellite, etc. It is because of its multifunction that the need of copper is large. Since 1980's, the world consumption of refined copper is: 904.67, 910.712, 994.41, 964.39, 1007.51, 1041.336, 1053.02, 1098.82, 1079.44, 1071.40, and 1073.13. The future need for copper will must increase greatly.

To the contrary, although the productivity of copper has increased a lot, it can not completely satisfy the need of modern industry. The shortage of copper concentrate leads to our demand for copper scrap recycling. Besides, from a long term,copper recycling is also inevitable since copper is unrenewable resource. As we mentioned, electrical industry is the main field of copper consumption, a large amount of copper wire scrap will be generated. 

The copper in these copper wire scrap are mostly in good condition. If most of copper wire scrap can be efficiently recycled and reused, it will produce great economical effect. Then how to efficiently recycle these copper scrap?

There exits many methods such as thermal decomposition, cryogenic freezing method, chemical agents, etc. Of them, I think the most economical and efficient method is mechanical method. Copper cable granulator and wire stripping machine are the two common machines in copper recycling. A good copper cable let your work half the done. 

Amisy is a professional manufacturer of copper cable granulator and wire stripping machine with 13 years’ experience. You can visit our website and know more about these two machines!

New Trend of Environmental Protection Industry

With many changes happen such as the great improvement of income per capita and environmental consciousness and the fast development of globalization, environmental protection also sees a series of changes. What are these new trends at present?

In the past, the development of environmental protection is mainly for the need of environmental benefit. Simply speaking, we are in a command mode. Now it is gradually replaced by Community-Market-Regulatory (CMR). Once it is completely formed, those sensitive multinational companies will expand quickly and strongly promote the development of environmental protection. For example, those companies in Japan, Korea and the West, invest in China and other Asian countries for existence in globalization. The giant in international investment, Buffett becomes a shareholder in BYD, the biggest manufacturer of battery, which shows its interest for new energy.

Besides, the market focus of environmental protection industry is gradually turning to developing countries. At present, demand in the domestic market of environmental protection in developed countries has tended to balance while the position of developing countries in this aspect has greatly improved. According to a survey of Caesar Consulting Company, an authoritative Germany company in environmental protection and biological sciences research, China’s environmental protection market grows quickly, including drinking water market, metal recycling market and solid waste recycling market. At the same time, other Asian countries also have good performance in environmental protection.

Asian countries not only have great potentiality in market, it also adheres to the manufacturer of recycling machines. For example, Amsiy is a renowned Chinese manufacturer of copper cable granulator and wire stripping machine. If you are in copper recycling, you can visit its website to have a understanding.

Magic Use of Copper’s Chemical Compound

We are familiar with these facts: Copper is the major of various fields. In fact, copper’s chemical compounds also have widely and magic use. Let’s know several kinds among them.

We know that copper is the main material of most electrical wires. If we want to ensure the good conductivity of copper, we must guarantee the purity of copper. Then how to remove the impurity in copper? In industry field, the commonly used method is electrolytic method. Here we need copper’s compound: cupric sulfate. Cupric sulfate is one of the most important copper’s chemical compounds. It is a kind of sky blue crystal, which has good sterilizing effect.

Moreover, we also can use cupric sulfate to distinguish whether there is water in organic solution. For example, if we want to know whether ethyl alcohol is mixed with water, we only need put some anhydrous cupric sulfate into alcohol. If the cupric sulfate turns blue, it proves that the alcohol contains water.

Another important copper’s chemical compound is cupric oxide. We know that paste is a frequently-used material. Once our books are broken, we can use paste to restore them. But if we need to connect two pieces of metal, how can we make it? There is a magic metal “paste”. First, we need to heat he mixture of ortho-phosphoric acid and calmogastrin; then put the powder of cupric oxide into the mixture and continuously stir the mixture, finally we get this metal “paste”. In the past, the cutter edge of lathe tools is welded.The hot welding temperature often reduces the hardness, thus shortening the lifetime of tools. But if we use this metal “paste”, the cutter edge can be closely connected with the mine body of tools without heating, the lifetime of tools can be doubled

We see the magic use of copper and its compound, and then we can have a further understanding of the importance of copper. Since copper is non-renewable resource, copper recycling is necessary. Copper cable granulator and wire stripping machine are commonly used copper recycling machines.

The Classification of Copper Scrap

Copper is widely used in various fields，therefore copper scrap is also a big family. How to define them? Generally, the classification of copper scrap is according to the content of pure copper. The common categories mainly include over 20 kinds.  Now come to know some of them. First, No.1 Copper Wire. It includes two grades. First grade is pure and naked copper wire without paint coat, alloy and broken filament, of which the diameter should not be less than 1.6 mm. Second grade is colorless pure copper wire and electrical cable without paint cover, tin and alloy, which not contain broken filament and burnt fragile copper wire. Another common kind of copper scrap is NO.2 Copper Wire. It refers to copper wire scrap without alloy. The copper content can not be lower than 94% and it can’t contain the following kinds: copper wire with excessive amount lead and tin; welding copper wire, yellow copper and bronze copper; copper wire with much oil, scrap steel and iron and nonmetal; etc. Purple copper scrap is also a main kind. It has three sub-grades: special purple composition copper scrap, No.1 purple composition copper scrap and No.2 purple composition copper scrap. Special purple composition copper comes from copper processing factory, like leftover bits and pieces, defective raw material, etc. No.1 purple composition copper refers to clean processing waste without alloy and painted coat. The copper content must be higher than 96%. No.2 purple composition copper is mixed pure copper scrap without copper alloy and its copper content should not be lower than 94% The last but not least kind is copper wire granule. It also has two grades: No.1 copper granule and No.2  copper granule. No.1 copper granule is made from copper scrap without painted coat and alloy while No.2 copper granule is made from copper scrap without alloy. The lowest copper content requirement is 99%. To get higher recycling rate, a good copper granulatoris very important. After we know these kinds, it is not difficult to find copper wire recycling is an important field. In copper wire recycling, you can’t miss copper cable granulator and wire stripping machine.
