Use of lubricating oil additives

Lubricating oil additive refers to a mixture of several single agents that are mixed according to a certain proportion and blending technology and can meet the requirements of a certain quality grade.
Before the 1980s, the additive raw materials of blended lubricating oil in China were basically single agents, that is, according to the quality requirements of the adjusted oil, select a certain nature of the base oil and add some additives that can improve the characteristics of a certain oil. Due to the low quality grade of lubricating oil and the simple requirements for oil performance evaluation, the blending technology of single dose raw materials is widely used. However, in the past ten years, the import of automobiles and the introduction of technology to produce automobiles have increased significantly, the quality requirements of internal combustion engine oil are also getting higher and higher, the use of single raw material technology to blend oil products is not only troublesome in the process, but also difficult in the formulation evaluation, most lubricating oil blending plants are difficult to do. Therefore, some manufacturers produce composite additives on the basis of bench evaluation, this composite agent has a variety of functions required for refined oil, as long as the appropriate dose is added to the specified nature of the base oil, you can produce a certain quality level of oil. The production process of blending lubricating oil with compound agent as raw material is simple, easy to operate, short production cycle and good economy.
