       Lubricating oil is generally composed of two parts: base oil and additive。Base oil is the main component of lubricating oil, determines the basic characteristics of lubricating oil, additives can fill and improve the performance of the base oil level is insufficient, granted some new properties, is a key component of lubricating oil。Lube base oilLubricating oilBase oil is mainly divided into two categories: mineral base oil and generated base oil。

       Mineral base oil is widely used and the amount used is very large (approxAbove 95%), but there are some application places must use the product of the generated base oil, so that the generated base oil has a rapid development trend。Mineral oil base oil is derived from petroleum。The key production processes of lubricating oil base oil are: normal distillation, organic solvent leaching, organic solvent processing, solvent dewaxing, clay or hydrocracking fill manufacturing 。The current standard specifications for lubricating oil base oil in our country were revised in 1995, the classification methods were changed, and the specifications for two special types of base oil, low coagulation and deep manufacturing, were promoted。The production of mineral lubricants requires the use of high quality petroleum。The composition of mineral base oils consists of high melting point, high relative molecular weight nitrogen compounds and non-nitrogen compounds。

Lubricating oil

       Its composition is generally ethane (net disc straight chain, carbon bond, polycarbon bond), cyclic hydrocarbons (monocyclic, biporous, polycyclic), aromatic hydrocarbons (monocyclic aromatic, polycyclic aromatic), cycloalkyl aromatic hydrocarbons and their oxygen content, nitrogen, sulfur content of organic compounds and collagen fibers, leach and other non-hydrocarbon compounds。Additives Additives are the essence of modern high-grade lubricating oil, appropriate use of reasonable addition, can improve its physical characteristics, grant new special properties of lubricating oil, or enhance its original performance of a certain class, to achieve higher regulations。According to the quality and performance of lubricating oil regulations, the additives are carefully selected, carefully balanced, and reasonable preparation is to ensuregreaseOil quality is important。Generally common additives are: viscosity coefficient change agent, pour point reducer, antioxidant, antioxidant, static thickening agent, friction moderator, oil solubility agent, anti-fire hydraulic oil, anti-foam agent, metal material passivation agent, demulsifier, anti-corrosion agent, anti-rust oil, demulsifier。
