Ultra-fine copper powder is a good conductivity, high strength nano-copper indispensable basic raw materials. Because of its excellent electrical properties, widely used in conductive adhesives, conductive coatings and electrode materials, in recent years found that can be used for the production of catalysts, lubricants additives, and even can be used for the treatment of osteoporosis, fractures and so on.
Ultrafine particle material refers to a powder whose particle size is between 1 and 100 nm, also known as a nanoparticle material (in which an ultrafine particle material is extended to a few microns in application). Nanoparticles have small size effects, large specific surface and macroscopic quantum tunneling effects, and thus nanotubes show many excellent properties that are not available for micron-grade powders. Nano-copper powder than the large surface area, the number of surface active center in metallurgy and petrochemical industry is an excellent catalyst. In the process of hydrogenation and dehydrogenation of polymer, nano-copper powder catalyst has a very high activity and selectivity, in the acetylene polymerization process used to make conductive fibers in the process, nano-copper powder is a very effective catalyst. In the process of vehicle exhaust purification, nano-copper powder as a catalyst can be used to partially replace the precious metals platinum and ruthenium, the toxic carbon monoxide into carbon dioxide, nitric oxide into nitrogen dioxide. With the development of the electronics industry, the ultra-fine thick film slurry prepared by nano-copper powder will play an important role in the large-scale integrated circuit, while the price is higher than the precious metal silver powder, palladium powder is low, has broad application prospects. Nano-copper lubricants additive is a new type of lubricating oil additive product guided by nano-tribology, which is guided by nanometer tribology. It has excellent anti-friction and anti-friction and energy saving and environmental protection. The addition of nano-copper lubricating oil additive to the engine oil will reduce the starting current of the engine and increase the cylinder pressure. The engine uses the additive for a period of time, the liner and the piston ring will form a protective film. at this time. Once the lubrication system fails, the car can safely travel for a long time, which is very meaningful in the military.
The development of nanometer copper powder is a key technology which may bring about the revolutionary change of copper and its alloy, which has important theoretical and practical value. Nano-copper powder research is still in the development stage, and its wide range of uses will make nano-copper powder research has a better market value and market prospects.
