What is the use of nano-copper?

Nano copper overview

Nano-copper is a product made of nano-materials and has superplastic ductility. It is a pure thing.

Articles made of nanomaterials have many peculiar properties. For example, nano-copper has superplastic ductility and can be stretched more than 50 times at room temperature without cracks. Researchers from the French National Research Center found that copper nanocrystals with an average volume of only 80 nanometers have amazing mechanical properties. The strength is not only three times higher than that of ordinary copper, but also the deformation is very uniform, without obvious regional narrowing. This is the first time that scientists have observed such a perfect elastoplastic behavior of matter. This mechanical characteristic of copper nanocrystals is that nano-copper is more likely to react with oxygen than ordinary copper.

The copper atoms in nano-copper are the same as those of ordinary copper, but the nano-copper particles are very small.

The chemical properties of nano-copper are more active than ordinary copper, and even change the inherent properties, but nano-materials do not change the state of matter.

The bactericidal mechanism of copper: Cu chemically reacts with water under aerobic conditions to produce hydroxyl radicals (-OH) and reactive oxygen ions (O2-). They have strong redox effects and can destroy the proliferation ability of microbial cells. Thereby inhibiting and killing microorganisms. The specific surface area of nano-copper increases, and chemical reactions are more likely to occur.

Copper is a heavy metal, and it is recognized that heavy metals have a bactericidal effect (such as silver). Heavy metals are all toxic, and reaching a certain dose in the human body will have an impact on health, and even cause disease and poisoning (silver also has certain neurotoxicity and genetic toxicity). Copper is one of the essential trace elements for the human body and can be metabolized and absorbed by the human body, while silver is difficult to metabolize in the human body and will be enriched in the human body. Therefore, Europe and the United States have banned the use of nano-silver as antibacterial agents, and some use nano-copper as an alternative.

The manufacture of elastic materials at room temperature opens up a bright future.

Application of Nano Copper

For the manufacture of chemical appliances, electrical appliances, building materials and other industrial installations and appliances.

Because copper has many excellent properties, it is widely used in various industrial sectors. Until the 1960s, the importance and consumption of copper was second only to iron. After the 1960s, it gave way to aluminum, which is richer in resources and cheaper, and retreated to third place. The proportion of copper consumption in China in the late 1980s is shown in Table 2. As far as the world is concerned, more than half of copper production is used in the power and electronics industries, such as the manufacture of cables, wires, motors and other power transmission and telecommunications equipment. After the 1980s, part of the use of copper in telecommunications was replaced by optical fibers. Copper is also an important material for the defense industry.

Because of the good conductivity of copper, it is widely used in the electrical industry. The manufacture of wires and cables requires pure copper (content above 99.95%), which is refined by electrolysis of blister copper. Copper can form a variety of important alloys with zinc, tin, aluminum, nickel, and beryllium. Brass (copper-zinc alloy) and bronze (copper-tin alloy) are used to make bearings, pistons, switches, oil pipes, heat exchangers, etc. Aluminum bronze (copper-aluminum alloy) has strong vibration resistance and can be used to manufacture castings that require strength and toughness. Monel alloy in the copper-nickel alloy is known for its corrosion resistance and is mostly used in the manufacture of valves, pumps, and high-pressure steam equipment. Cupronickel is a copper-nickel alloy with good mechanical properties and corrosion resistance and is used in precision machinery manufacturing. The mechanical properties of beryllium bronze (containing beryllium copper alloy) exceed high-grade high-quality steel, and it is widely used in the manufacture of various mechanical parts, tools and radio equipment.

Copper compounds are important raw materials for pesticides, fungicides, pigments, electroplating, galvanic cells, dyes and catalysts.

Because of its high purity and no hydrogen embrittlement, oxygen-free copper is used in waveguides, vacuum tubes and transistor components, glass and metal sealing, coaxial cables, and the stabilization of superconducting magnetic windings. Tough copper is used to make copper bus bars, contactors, various types of conductors, radar components, switches and contacts, etc. The above-mentioned two kinds of copper are processed by adding silver to make devices that require anti-softening, such as windings of transformers, generators and large-scale synchronous generators. Phosphorus deoxidized copper is mainly used to make pipes for refrigerators and air conditioners, rectifiers, water pipes or gas pipes, etc. (when electrical and thermal conductivity, as well as welding performance or brazing performance is required). Free-cutting copper is mainly used to manufacture threaded products and other welding tips, fixtures, terminals and switch parts.

Nano-copper has excellent electrical conductivity, ductility and corrosion resistance. Nano-copper can not only significantly improve the wear resistance of lubricating base oil within a certain experimental range, reduce friction performance, but also significantly increase the load-bearing capacity of lubricating oil ability.

Nano copper powder can be used as a lubricant additive, and it is a new type of lubricant additive mainly used in various automobile engines. Nano copper powder has repair function and efficient heat dissipation function, which can reduce the wear of automobile engine by 80%.

Nano-copper is used as thermal hydrogen generator, gel propellant, combustion activator, catalyst, water cleaning adsorbent, sintering activator, antibacterial agent, wear, corrosion, and fatigue are three forms of mechanical material failure. The economic loss caused by wear is huge. About one-third of the world's primary energy is consumed by friction, and nearly 80% of parts are scrapped and worn due to friction. Reducing the use of lubricating oil is the most effective means to reduce friction or avoid wear. As a lubricating additive to improve the quality of lubricating oil is the focus of research in various countries. The lubricating oil made of materials added to the lubricating oil can significantly improve its lubricating performance and carrying capacity. Reduce the coefficient of friction, reduce friction resistance, and extend the life of the machine. This is one of the most successful applications so far. Under the action of the electric field formed by the friction process, the nano-particles are deposited on the friction surface through electric pulse motion to form a dense protective film, which shows good anti-friction and anti-wear performance. At the same time, under high load and at high speed, nano-copper The addition of can effectively improve the anti-wear performance of engine lubricating oil and prolong the service life of engine wearing parts.
