Problems solved by technology

[0005] One is to add a slip modifier to the lubricating oil (grease). The principle of this type of technology is to form a lubricating film on the contact surface between the friction pairs, with a thickness of several nanometers to tens of nanometers, which can reduce the friction between the friction pairs. The coefficient of friction reduces the frictional resistance. Its effect is equivalent to improving the lubricating index and lubricating performance of the lubricating oil and prolonging the service life of the lubricating oil. In essence, it is the optimization and modification of the lubricating oil itself, but it has the function of repairing the friction wound. relatively weak
[0006] The second is to add inorganic repair materials (such as serpentine, borate, etc.) to the lubricating oil (grease). The above-mentioned substances in the base react very slowly with the base surface (generally it takes several months), and a ceramic alloy film is formed on the contact surface, with a thickness ranging from tens of nanometers to tens of microns, which can continuously repair the friction wound The main feature is that the long-term repair function is relatively strong, but the effect is relatively slow. In essence, it is the optimization and modification of the friction base surface. The optimization of the lubricating oil (grease) is relatively weak, and the lubricating performance of the lubricating oil (grease) cannot be immediately improved. During the formation of the alloy film, the operating state of the lubricating oil does not improve much, and the lubricating performance will normally decay. After the formation of the alloy film, due to the greatly reduced friction coefficient, the friction energy will also decrease, and the lubricating oil will also prolong. (grease) service life, but the real reason is that the normal operation of the frictional movement has lower requirements on the performance of the lubricating oil than before the formation of the alloy film, rather than the improvement of the performance of the lubricating oil
