Energy saving, environmental protection and climate changes have become the common problems and hot spots of economic development. Currently, one third of world's energy is consumed in the friction loss. Especially in the environment of growing tension of oil and coal resources, rising raw material prices and growing environmental pressures, the market proposes higher and more requirements for lubricating antifriction materials. The lubricants and greases with better lubricating properties, longer life cycle and self-healing properties are continuing to emerge. They become the hot spot in market.

In the number of metal powder materials, because of its excellent thermal conductivity, electrical conductivity, wear resistance, non-magnetic, chemical stability, bright colors and unique antibacterial, coupled with the basic characteristics of the powder material, copper powder (FCu) is widely used in carbide, diamond tools, welding electrodes, friction materials, catalysts, coatings, conductive ink, electronic, medical and bio-tech fields. It has an increasingly wide range of applications and great potential. In anti-electromagnetic interference coatings of stealth aircraft, anti-electromagnetic interference device ultrafine also use the copper powder.

More than ten years, nano-copper powder in the field of friction and lubrication applied research has made significant progress in nano-copper powder as a functional additive, has greatly improved the thermal conductivity of the lubricant, wear self-healing performance. However, due to the high cost of production of copper nanoparticles, only the repair without lubrication, the color was black and similar waste oil, nano-copper powder is easily oxidized to black copper oxide, the key is there is not enough copper nanoparticles supply market, it added the lubricating oil of the copper nanoparticles has not been popularized.

Micron copper powder as a lubricant additives will change the traditional sliding lubrication rolling and sliding compound lubrication, the friction coefficient will be greatly decreased, the lubricating effect, better than the lubrication and repair the effects of high-grade lubricants on the market today. Friction surface self-healing, dispersion, forming an excellent 0.5 ~ 1.5um ultra-fine copper powder in the lubrication process will effectively fill the machining damage surface in the recess to achieve repair parts of the fill, a considerable improves precision machining accuracy and reduce the friction coefficient.

The protection of the friction surface, the lubricant contains millions of ultra-fine micron copper powder elastic particles, according to theoretical calculations for each micron copper powders can withstand the pressure of more than 150 kilograms, so that the cold start and high load can reduce the direct contact between the friction loss in the mechanical surface, to protect and extend the life of the engine; in improving the lubrication properties, millions of micron ultra-fine powder, equivalent to a number of ball directly change the slide friction and rolling friction, the friction coefficient is greatly reduced, power consumption is greatly reduced at the start and accelerate to naturally achieve a fuel-efficient and energy saving;

In compatibility aspect, with inorganic and organic surface treatment in ultra-fine copper powder by metal powder supplier, organic layer and lubricating oil has good compatibility and stable dispersion. In terms of liquidity, biggest particle size of micron ultra-fine copper powder is less than 1.5 microns. It is smaller than 5 micron pore size of oil filter cartridge. The ratio of lubricating oil is not high. The micron-level ultra-fine copper powder will be without sub- layer in more than a month if is dispersed by a certain percentage. Coupling with the pressure transportation and mixing of fuel injection pump in the using process, it resolves the problem of filter clogging and insufficient oil supply.Source:http://www.mhcmp.com
