The Introduction of Nano-Copper Colloidal

Nano-Copper Colloidal

Nano-Copper Colloidal of different particle size were dark purple to black, with no other colors mixed, spherical, no significant agglomeration.
Products made with nanomaterials has many peculiar properties. For example, nano-copper with superplastic ductility at room temperature can be stretched more than 50 times without cracks. Recently, the French National Scientific Research Center study found that the average size of only 80 nm nano-crystals of copper amazing mechanical properties, strength is not only three times higher than ordinary copper, and the deformation is very uniform, no significant narrowing of regional phenomena. This is the first time scientists have observed such a perfect elastic-plastic material behavior. This copper nanocrystals at room temperature mechanical properties for the manufacture of flexible material has opened up a bright future. Hydrogen generator for heat, gel propellants, combustion activity, catalyst, adsorbent water clean, nano-copper sintered active agent more likely than the average copper reacts with oxygen in the nano-copper copper copper copper atoms and ordinary atoms Like, just a very small nano-copper particles. Chemical properties of nano-copper showing more lively than the ordinary copper, and even change the inherent nature of that, but does not change the substance of nanomaterials is the state.
Uses:
Metal nano lubricant additive: Add 0.6% to 0.1 lubricating oil, grease, in the process, to Mount Sassafras Sassafras Vice surface friction self-lubricating, self-laminating, Vice significantly improve Friction friction anti-wear performance.
Metal and non-metallic conductive coating on the surface: nano aluminum, copper, nickel powder has a high activation of the surface, under anaerobic conditions at a temperature below the melting point of the implementation of powder coating. This technique can be applied to the production of microelectronic devices.
Efficient catalysts: copper and its alloys nano-powder as catalyst, high efficiency, selectivity, carbon dioxide and hydrogen can be used for methanol synthesis catalyst during the reaction.
Conductive paste: for MLCC internal electrode terminal and make miniaturization of microelectronic devices. With its superior performance alternative to precious metal powder preparation of electronic slurry, can greatly reduce costs, optimize microelectronics technology.
Bulk metallic nano-materials with raw materials: the use of inert gas bulk copper metal powder sintering nano-composite structure materials. Drug added materials: for the treatment of osteoporosis, osteoarthritis and other new cure for the added material. Nano-metal self-healing agent: metal machinery and equipment added to the friction in the lubricant, the friction has worn metal parts to achieve self-healing, energy consumption, improve equipment life and maintenance cycle.
