Lubricant Additive Significantly Improve The Use Of Performance Jul 04, 2017

For lubricants users, the viscosity of lubricants is more familiar with the concept, because the viscosity is the primary indicator of the purchase of lubricants. For the already used lubricants, viscosity is also an important indicator of concern in the test. The composition of the lubricating oil is the base oil and some Lubricant Additives, the viscosity of the main and the base oil. In addition to base oils, Lubricant Additives also play an important role in lubricants. Good lubrication on the role of Lubricant Lubricant Additive to do a brief introduction.

Lubricant Lubricant Additive are some organic or inorganic compounds, some are liquid, can be dissolved in the lubricating oil, some are solid, suspended in the lubricating oil. Lubricant Additives in the lubricating oil content is small, depending on the type of oil, the content of 0.1% to 30% (volume ratio) range, some lubricants contain more Lubricant Additives, such as oil, some lubricants contain less Lubricant Additives, Such as turbine oil.

The role of lubricating oil Lubricant Additives is divided into three areas:

To further enhance the base oil itself has some of the properties, such as antioxidants, rust inhibitors, anti-foam agent, anti-emulsifier.

The basis of the lack of performance of the base oil to make up, such as pour point depressant, viscosity index improver.

Giving the base oil new performance, that is, the performance of the base oil itself does not have, these properties are mainly achieved by Lubricant Additives, such as extreme pressure (EP), dispersant, metal deactivator.

Lubricant Lubricant Additive will be adsorbed to the surface of impurity particles, and surrounded by impurities wrapped around, such Lubricant Additives are mainly metal deactivators, detergents, dispersants. In the case of dispersants, it can adsorb solid small particles such as carbon and impurities, disperse them in the oil, prevent the accumulation of impurity particles to form large particles of sediment. Clean dispersant is an important Lubricant Additive in automotive engine oil.

Although the Lubricant Additive has an enhanced effect on the performance of the lubricating oil, it does not mean that the benefits are better. There are two possible consequences of the excessive use of the Lubricant Additive in the lubricating oil: one is to reverse the performance of the lubricating oil. For example, if the concentration of the clean dispersant added is higher than the normal level, the clean dispersant will surround the antiwear or extreme So that they are suspended in the oil, resulting in extreme pressure and anti-wear agent when needed, where the need to form an effective protective layer, the result is increased wear. If the use of anti-wear agent excessive, will cause the performance of metal rust preservatives to reduce, as previously said, the Lubricant Additive will be adsorbed on the surface of polar substances, including metal. If the anti-wear agent is excessive, will be adsorbed to the metal surface, the rust may not be local adsorption, resulting in anti-rust anti-corrosion effect. Therefore, the Lubricant Additive is not a lot of the better, to maintain a variety of Lubricant Additive formulations balance, is a necessary condition for high-quality lubricants.

If the Lubricant Additive is used too much, there is a result that the relative performance of the lubricating oil is not enhanced, but the extension of the Lubricant Additive is extended. But as a user, there is generally no way to understand the consequences of the use of certain Lubricant Additives, therefore, do not recommend the user to add their own Lubricant Additives. In some cases, if necessary, consult the oil supplier or add it under the guidance of the oil inspection laboratory.

Lubricant Additives in the development process is worth mentioning is ZDDP. This compound was originally used to solve the problem of corrosion of copper-lead bearings, and later found that ZDDP also has excellent antioxidant and anti-wear properties, which makes ZDDP become the most popular anti-oxidation, anti-corrosion, anti-corrosion effect Lubricant Additives, has been applied for more than half a century. In the early 1960s, non-polymerized succinimide ashless dispersant was developed and applied abroad. It has excellent low temperature dispersion performance and has a significant effect in improving the low temperature sludge, thus effectively solving the problem of low temperature sludge. Succinate dispersant and metal detergent compound also has a synergistic effect, can significantly improve the use of lubricating properties, and reduce the Lubricant Additive dosage, which is a major breakthrough in lubricant Lubricant Additive technology.

The late 1960s, foreign countries have been basically the main types of internal combustion engine oil Lubricant Additives, namely, metal detergent, ash dispersant and ZDDP become the engine engine oil three functional Lubricant Additives. In the 1970s, the researchers on the one hand the various types of Lubricant Additives for chemical structure adjustment and series of serialization, so that a single performance more features, and further study the compound effect of these Lubricant Additives, in order to meet the economic principles, Lubricant Additives have better overall performance. After the 1980s, Lubricant Additives on international markets were sold more in the form of composite Lubricant Additives, the reason for this.
