The importance of detergent dispersive additives in lubricating oil

The importance of detergent dispersive additives in lubricating oil

One is that the lubricating oil can suspend the insoluble substances such as colloid and carbon deposit formed after oxidation in the oil to form a stable colloidal state and is not easy to deposit on the parts;

The second is to wash the colloids and carbon deposits deposited on the engine components through lubricating oil washing. Detergent dispersant is a substance with surface activity. It can adsorb solid particle pollutants in oil and suspend pollutants on the surface of oil to ensure that the oil participating in lubrication cycle is clean and reduce the formation of high temperature and paint film. The dispersant can disperse the low-temperature oil sludge in the oil to filter it out in the lubricating oil circulation. Detergent dispersion additive is the general name of them. It also has the functions of washing, anti-oxidation and anti-corrosion. Therefore, it is also called multi effect additive. In a sense, the quality of lubricating oil is mainly different in the performance of resisting high and low temperature deposits and paint film formation. It can also be said that it is reflected in the performance and amount of detergent dispersant in lubricating oil. It can be seen that detergent dispersant has an important impact on the quality of lubricating oil.
