As a good lubricating medium, nano-copper powder has been widely recognized by international authoritative organizations, and has been applied in some cutting-edge projects in the developed countries of the United States and Europe. Its lubricating effect and self-repairing function are unmatched by general lubricants and organic additives, and the potential application of this technology is very wide, such as various high-load working conditions such as automobiles, ships, airplanes, tanks and mining machinery. The equipment underneath can greatly improve the wear resistance of high-speed moving parts such as precision machinery and aviation.
The nano copper powder lubricating oil additive developed by the technology adopts a completely different concept compared with the lubricating oil organic additive currently widely used on the market. The nano-copper powder in the nano-copper powder lubricating oil additive acts as a buffer on the surface of the friction workpiece during the circulation of the oil circuit, and the nano-copper powder has better high-temperature chemical stability with respect to the organic additive, and therefore, fundamentally It solves the problem of agglomeration and carbonization which may occur in lubricating oil at high temperatures. More importantly, the nano copper powder is fine and soft, and can be filled with friction defects at any time to play a self-repairing effect. The function of nano copper lubricant additive is mainly reflected in:
1. Reduce frictional resistance, improve engine effective power and extend engine life;
2. Eliminate damage to the engine from initial start-up and save fuel consumption;
3. Improve the efficiency of the lubricating oil and ensure the power output of the engine.
The nano copper powder in the nano copper powder lubricating oil additive belongs to the ultrafine metal powder material, and the preparation of the material is a key research project in the national “10th Five-Year” science and technology development plan.
Technical indicators
Experimental studies have shown that the addition of 0.1% nano-copper powder lubricant additive to the lubricating oil can reduce the friction coefficient by 30%, the wear by 34%, the fuel economy by 5%, and the average fuel consumption by 3%.
The technology has reached the industrial scale production level, the average particle size of the nano copper powder is adjustable within the range of 2 to 30 nm, and the product repeatability between the batches is good and the quality is stable.
Application range
This technology has a wide range of applications, which can greatly improve the wear resistance of high-strength, high-load equipment such as high-speed components such as precision machinery and aviation, such as automobiles, ships, airplanes, tanks and mining machinery.
