Granulated Copper is a course granular solid with a cylindrical shape with slight metallic odour. The length ranges between 0.9 and 6.0 mm with a mean at 2.1 mm and the width ranges between 0.494 and 0.949 mm with a mean at 0.706 mm. Its melting point is 1059-1069°C. It is not required to test for vapour pressure as the melting point is above 300ºC. Solubility in water is pH dependent (acidic conditions). The solubilisation results of the oxido-reduction reaction of the copper metal into ionic copper. Cu(0) → Cu(I) → Cu (II). At low pH, these reactions are promoted. At pH 6.34-7.56 and at 20 °C the solubility is 1 mg/L.

Benefits of copper wire recycling

Copper is an extremely sought-after metal for recycling due to its efficiency and durability. It is one of the most profitable types of scrap metal and can easily be found in homes or businesses. From old, outdated appliances and electronics, to plumbing and auto parts, there are many places to find scrap copper quickly and easily. This extremely durable metal is often used for wires as it does not lose its electrical connectivity over time. Unfortunately, this means that it does not break down with regular waste, which doesn’t take advantage of its longevity and needlessly fills up landfills.

Copper can be recycled repeatedly for massive environmental and economic benefits. Copper retains its performance despite being recycled multiple times making it an economical metal for a range of industries. The process of recycling copper not only produces less carbon dioxide and greenhouse gases, but it requires less energy and effort than the costly process of extracting and refining raw, virgin iron. Using scrap metal to its full capacity by recovering copper and stripping the shielding from cables and wires, benefits businesses, the environment and you.

Copper wire is an essential material for motor and transformer winding. Copper wire is available in different gauges (32 gauge to 18 gauge). The gauge of the copper wire depends upon the winding required for the specific motor or transformer. The wire having conductor diameter from 0.500 to 4.000mm, is suitable for submersible motor winding. There is a heavy market for copper wire/enameled copper wire in motor and transformer manufacturers and this wire is also used in rewinding of motors and transformers. Reasons for its wide use is that the copper has resistance to atmospheric corrosion because of the form ation of uniform layer of oxide on the surface of metal.

Benefits of Using Copper Wire

Copper wire is the most preferred wire today for umpteen critical industries, like electronics, telecommunications, construction, marine, and soforth. These great features of Copper wire have made it an obvious choice for these industries.

Flexibility: Flexible in nature, Copper wire can be Moulded, cut and blend to suit the needs. Such need is widely required in industries such as marine and construction.

Conductivity: Copper is the second highest conductivity element, with silver being the most. Because of the extremely high electrical and thermal conductivity features of Copper wire and less expensive than silver, make Copper wire the most sought after wire for industries

Melting Point: Since Copper displays absolutely high melting point, it suits to the needs of industries like electrical and construction.

Strength: Copper wire is very strong as it is made out of high tensile Copper Ore. In industries like telecommunication where wire is used for signal transmission across long distance, wire of similar strength is required.

Compatible: Copper wires such as bare copper wire and tinsel copper wire are highly compatible with one another, and they can form brisk mixture should there be need.

One of the primary factors that marked the evolution of the human beings is the advent of technology. What started as the invention of wheel has got us to ace age of technology and innovations. The use of technology can be experienced everywhere near us. However, the basic factor that drives most of the technical machines is electric current. In order to transfer the charges bearing the current, the use of conducting wires is extremely important. The current conducting wires should have the required features as per the needs that would make them a proper candidate. One such wire is the submersible winding wire.

Basic Features of the submersible winding wire:

The submersible winding wires are also known by the name of poly winding wires. There are many types of machinery where mechanical abrasion and corrosion is very common. Along with that, some industrial machines are also exposed to high temperature. In addition, there are various kinds of machinery, which are required to carry out their functions underwater. In such conditions, one should not call for the regular wires because such extremities can cause the wires to break down thus inviting un-called for hazards. It is for such situations where the submersible winding wires comes to rescue so that the regular operations performed by the machines can be carried on smoothly and safely.

Copper Oxychloride 50% WP is a copper based broad spectrum fungicide which controls the fungal as well as bacterial diseases by its contact action. It also effectively controls the fungus resistant to other fungicides. Due to its fine particles, it sticks to the leaves and helps to restrict the growth of the fungus.

Copper based fungicides/bactericides are used extensively in agriculture. It has been observed that various types of copper compounds can be used to effectively treat various plant pathogens, and are available in different types of formulations including wettable powders, emulsifiable concentrates, water-based flowables and dry flowables (also known as water dispersible granules). Dry flowable products are generally dustless, free-flowing, granular products. They are popular among users because the products can be formulated with a higher percentage of active ingredients, are easy to use and have improved shelf life compared to the aqueous fungicides/bactericides. Dry bactericides/ fungicides can be stored for a long period of time, over wide extremes of temperature, without destroying the stability of the formulation.

While copper compounds have been known for their ability to control fungi/bacteria, the copper materials applied must be relatively non-toxic to the plants. Generally, inorganic copper compounds have been used because they have been observed to be non-phytotoxic, whilst most of the organic copper compounds have been found phytotoxic, especially in foliar applications.

With respect to the inorganic copper compounds, water soluble copper compounds are known to be extremely phytotoxic. As a result, water insoluble copper compounds are used as fungicides/bactericides.

Biological activity of the copper-based fungicides/bactericides is measured by the free Cu2+ ions available for consumption by the fungi or bacteria. The biological activity of a fungicide/bactericide increases with an increase in the amount of free Cu2+ ions released. Therefore, the fungicides/bactericides formulated based on water insoluble copper compounds are normally applied in relatively large amounts to effectively control the phytopathogenic fungi.

Dicopper chloride trihydroxide is the chemical compound with the formula Cu2(OH)3Cl. It is often referred to as tribasic copper chloride (TBCC), copper trihydroxyl chloride or copper hydroxychloride. It is a greenish crystalline solid encountered in mineral deposits, metal corrosion products, industrial products, art and archeological objects, and some living systems.

Natural occurrence

Cu2(OH)3Cl occurs as natural minerals in four polymorphic crystal forms: atacamite, paratacamite, clinoatacamite, and botallackite. Atacamite is orthorhombic, paratacamite is rhombohedral, and the other two polymorphs are monoclinic.

Atacamite and paratacamite are common secondary minerals in areas of copper mineralization and frequently form as corrosion products of Cu-bearing metals.

The most common Cu2(OH)3Cl polymorph is atacamite. It is an oxidation product of other copper minerals, especially under arid, saline conditions. Its color varies from blackish to emerald green. It is the sugar-like coating of dark green glistening crystals.

It is intended to prepare a Feasibility Report to install 3000 MT/Year Copper Oxychloride production facilities as a Green Field Project.

TYPES OF ELECTRICAL WIRES

There are two main types of wires: solid or stranded.

A solid wire is a single conductor that is either bare or insulated by a protective colored sheath. It offers low resistance and is perfect for use in higher frequencies. When inside a covering there are many thin strands of wires twisted together, it is called a stranded wire. Stranded wires are used where flexibility is important because which the wire can be used for a longer period. This type of wire have larger cross-sectional area than solid wires for the same current carrying capacity. Stranding is process of twisting together of small wires to form a single larger conductor. Used to provide flexibility, ease of handling and vibration resistance.
