Organic and inorganic composite nano-copper powder particles obtain the praise from international experts as lubricating oil additives. Due to its technical advantage and price advantage, copper nanoparticles additive is expected to become the first nanomaterials lubricant additive in large-scale applications.
The mainstream of development of nano-lubrication technology is to solve the stable dispersion of nanomaterials in the oils and greases.
Conventional nano-materials, such as simple inorganic or pure metal powder, it is difficult to be a stable dispersion in the lubricating oil will still be in the lubricating grease. Researchers make modification of nanomaterials. They make organic matter composed by copper powder (FCu) modified nanomaterials. The nano-copper is an approximately 3-7 nanometers nuclear surrounding nanotechnology nuclear dialkyl dithio phosphate organic composition of organic and inorganic composite. Composite surface of the organic compounds and lubricants are immiscible, the material is very stable dispersion in lubricant. As commonly used in lubricating oil detergent. Detergent is actually a dispersing agent. It has a stable dispersion function. This nano-copper powder additives on the lubricating oil inside a year are not subsidence, has solved the stability of the problem of fragmentation.
The nanomaterials additives in a stable dispersion, but also lubrication wear resistance and other properties. In addition to the antifriction, antiwear, and improve the bearing capacity, the nano-copper powder, but also has a very significant performance of antioxidant activity. In addition, this technology R & D personnel for decentralized clear dispersion properties of coke. The results show that the adverse effects of copper powder materials on coke.
Nano-materials costs are also nano-additives, whether the application is an important factor in the field of conventional lubrication. Copper nanoparticles additive cost is acceptable. At present, the copper nanoparticles additive per ton of 30 million RMB, and may soon do the 10 million tonne to 20 million RMB. Production scale up to 100,000 RMB per tonne or lower, there is hope.
The achievements solve the abrasion resistance, reducing abrasion and self-healing problems of engine and transmission machinery. The metal powder supplier also takes into account the oil circulation dynamics process. The nano copper powder’s particle size, content and lubrication media stick consistency are optimized to achieve the best cooling effect. It ensures lubrication repair function. The high thermal conductivity plays a key role in delaying lubricant oxidation, while improves the thermal effects of the carnot cycle. The product does not have problems of agglomeration and carbonization in high temperatures. The implementation of the project has great significance in energy conservation, extending the engine and transmission and other equipment life, reducing wear, exhaust and noise pollution.
