Composite additives for oil products refer to additives that are composed of two or more additives with different functions mixed in a certain proportion. The main purpose of adding complex additives to oil is to improve the performance of the oil to meet the needs of practical applications. This article will introduce the functions, types, addition ratios and practical application cases of oil additive complexes.
The compound of oil additives has a variety of functions, including: improving oil quality, improving oil performance, preventing oil deterioration, enhancing oil stability, etc. Common oil additive compounds include fuel additives, lubricating oil additives, hydraulic oil additives, etc. The ingredients contained in these compound agents include detergents, antioxidants, metal passivators, anti-wear agents, extreme pressure agents, etc. These ingredients are mixed according to different proportions to achieve different effects.
For different oil products, the types and proportions of compounding agents that need to be added are also different. For example, for diesel engine oil, detergents and dispersants need to be added to reduce engine carbon deposits and soot generation; for hydraulic oil, anti-wear agents and extreme pressure agents need to be added to improve the stability and pressure resistance of the hydraulic system. ; For vehicle oil, detergents, antioxidants, metal deactivators, etc. need to be added to reduce engine wear and extend the oil change interval.
A diesel engine manufacturer used lubricating oil with compound additives in actual production, which significantly improved the fuel economy and emission performance of the diesel engine. Specifically, by adding detergents and dispersants to the lubricating oil, the friction and wear inside the engine are effectively reduced, the fuel injection and combustion processes are optimized, and the fuel consumption of the diesel engine is reduced by more than 10%. emissions.
In summary, oil additive complexes play an important role in improving oil performance. Through reasonable component ratio and selection of appropriate additives, the quality and stability of oil can be significantly improved, the fuel injection and combustion process can be optimized, engine wear and emissions can be reduced, the operating efficiency of the equipment can be improved, and the service life can be extended. Therefore, when selecting oil additives, you should fully consider the actual application needs, select a suitable compound agent and use it according to the recommended addition ratio to achieve the best results.
If you are specifically looking for compounds to identify oil additives in lubricants, spectroscopic techniques, such as infrared (IR) or nuclear magnetic resonance (NMR) spectroscopy, are commonly used for additive analysis in lubricants. These technologies allow the identification and quantification of specific compounds present in lubricants.
Infrared spectroscopy analyzes the absorption of infrared light by different functional groups in a molecule, providing information about the chemical composition of the oil and the presence of specific additives.
Nuclear magnetic resonance spectroscopy uses the magnetic properties of atoms to provide detailed information about the chemical structure and composition of molecules. NMR can be used to identify specific additives and determine their concentration in lubricants.
These spectroscopic techniques are extremely useful in the analysis and quality control of lubricants, allowing manufacturers to determine the presence and concentration of additives, monitor their effectiveness, and ensure that the lubricant achieves required performance characteristics.
