Brief Introduction of Lubricant Additive Ashless Dispersant
2019 / 10 / 10
Lubricants are composed of a base fluid and additives. The base fluid can be mineral, synthetic, or biological in origin. In terms of use, petroleum-derived (mineral) base fluids top the list, followed by synthetic fluids. Base oils of biological origin, that is, vegetable and animal oils, have not gained much popularity except in environmentally compatible lubricants. This is because of the inherent drawbacks these base oils have pertaining to their oxidation stability and low-temperature properties. Additives are added to the base fluid either to enhance an already-existing property, such as viscosity, of a base oil or to impart a new property, such as detergency, lacking in the base oil. The lubricants are designed to perform a number of functions, including lubrication, cooling, protection against corrosion, and keeping the equipment components clean by suspending ordinarily insoluble contaminants in the bulk lubricant. Although for automotive applications all functions are important, suspending the insoluble contaminants and keeping the surfaces clean are the most critical. As mentioned in on [detergents," this is achieved by the combined action of the detergents and the dispersants present in the lubricant. Dispersants differ from detergents in three signifcant ways: 1. Dispersants are metal-free, but detergents contain met
Market Analysis Of Lubricating Oil Industry
2019 / 10 / 10
Market Analysis Of Lubricating Oil Industry With the continuous development of the global automotive industry, the car ownership has been rising, and the demand for lubricants has been increasing. Although the global supply and demand for lubricants have shocked, they have basically maintained stable growth. China is a big automobile producer, and the car ownership is also increasing year by year. The demand for automobile lubricants is the main factor to promote the scale of China's lubricant industry. At present, the import quantity of lubricating oil industry in China is still larger than that of export. The imported lubricating oil is mainly high-end and special lubricating oil. Lubricating oil generally consists of base oil and additives. Base oil is the main component of lubricating oil, which determines the basic properties of lubricating oil. Additives make up for and improve the deficiencies of base oil performance, and give new performance, which is an important part of lubricating oil. Base oil, as the lower end product of crude oil industry chain, is extracted from petroleum by physical distillation. According to the classification criteria proposed by the American Petroleum Institute (API), base oils can be divided into five categories according to saturated hydrocarbon content, viscosity index and sulfur content. At present, China's base oil consumption is mainly based on API type I base oil and API type II base oil and non-standard products.
Global Demand for Lubricant Additives Reached 4.4 Million Tons in 2023
2019 / 10 / 09
With the development of industrial technology, the high speed, high performance, high automation, high efficiency and long service life required by modern equipment. It is difficult to use mineral oil lubricant alone in lubrication. Adding a small amount of other substances in lubricating materials can improve its performance and give it new characteristics. These substances are called additives to lubricants. Lubricant oil additives can be divided into Detergent, Dispersant, High Temperature Antioxidant, Corrosion Inhibitor, Antiwear EP Additive, Pour Point Depressant ect..And different additives have different effects. Adding different additives to oil products is the most economical and effective way to improve oil quality. Generally speaking, the variety and quality of lubricating oil often depend on the variety and quality of additives. Therefore, the development of production and use of additives has become an important way to make rational and effective use of resources, improve equipment performance and save energy. According to the June 9 Report of Chemistry Weekly, USA, IHS Markit's latest research report shows, In 2018, the global market demand for lubricant additives reached 4.2 million tons, with a market value of abo
Brief Introduction of Lubricant Additive Detergent
2019 / 10 / 08
Brief Introduction of Lubricant Additive Detergent Modern equipment must be lubricated to prolong its lifetime. A lubricant performs a number of critical functions. These include lubrication, cooling, cleaning and suspending, and protecting metal surfaces against corrosive damage. Lubricant comprises a base fluid and an additive package. The primary function of the base fluid is to lubricate and act as a carrier of additives. The function of additives is either to enhance an already-existing property of the base fluid or to add a new property. The examples of already-existing properties include viscosity, viscosity index, pour point, and oxidation resistance. The examples of new properties include cleaning and suspending ability, antiwear performance, and corrosion control. The extent of the desirability of various properties differs from lubricant to lubricant and largely depends on the conditions of use. Automotive use, for example, requires lubricants with good oxidation resistance, suitable low and high temperature viscosities, high-viscosity index (i.e., minimum loss in viscosity with an increase in temperature), and good cleaning and suspending ability. Conversely, the use as nonautomotive lubricants, such as industrial and metalworking lubricants, emphasizes oxidation resistance, antiwear performance, corrosion control, and cooling ability.
Introduction Of Antifoaming Agent For Lubricating Oil
2019 / 10 / 08
Introduction of Antifoaming Agent for Lubricating Oil During World War II, the foaming of lubricants used by American aircraft and vehicles caused serious problems. In order to find out the principle and solution of lube oil foaming, some oil companies and research institutes at home and abroad have studied it. In 1943, the company and Gulf company also discovered that liquid organosiloxane is a very effective antifoaming agent, so far it is the most important anti foaming agent in lubricants. At present, there are three main types of anti-foaming agents in the market: silicon-containing, non-silicon and composite anti-foaming agents. Here are the following anti-foaming agents. Performance of Antifoaming Agent: There are many reasons for the foaming of lubricating oil. Firstly, the oil itself is oxidized; secondly, the high-speed stirring of lubricating oil containing air; thirdly, various additives are used in oil products, especially those with active surface; there are several ways to solve the foaming of lubricating oil: physical anti-foaming method, mechanical anti-foaming method, chemical anti-foaming method, among which chemical anti-foaming method is the most commonly used.
How To Use P/N/S Sontaining Additives in Automotive Engine Oil
2019 / 09 / 30
Vehicle emissions legislation (e.g., in the United States, Europe, and Japan) now exists to control and substantially reduce the levels of particulates, hydrocarbons, carbon monoxide, and oxides of nitrogen in the engine exhaust. The engine manufacturers have met these requirements by a variety of design changes that impact the composition of oils and fuels in the following ways: • The introduction of catalytic converters to oxidize the hydrocarbon and carbon monoxide components to carbon dioxide and water, and reduce the nitric oxide (NO) to nitrogen, has been very successful in reducing emissions. When they operate at their normal operating temperature and optimum level of effciency, they are almost 100% effcient and most of the remaining emissions occur in the time before the catalyst reaches [light-off" temperature. Many studies into reducing this period to achieve yet lower emissions have been conducted. Although much success has been achieved, further progress may be hindered by the formation of a deactivating flm on the catalyst surface by the phosphorus from the ZDDP antioxidant and AW/EP additive. As a consequence, there is pressure to reduce the phosphorus content of engine oils to minimize catalyst fouling. Currently, oil specifcations such as ILSAC GF-4 and ACEA Cx limit the phosphorus content of both diesel and gasoline engine oils to 0.05–0.09% wi
70th Anniversary of China, 70 Years Development of Lubricant Additive
2019 / 09 / 29
Warmly celebrate the 70th anniversary of the founding of the Peoples Republic of China! As one of the 1.4 billion Chinese, I am sincerely proud. The 70 years of new China development is 70 years of rapid development in various industries, it is also 70 years of rapid development of Lubricant Additive industry. Lubricant Additive industry in China started relatively late. In the middle of 1950s, a set of small industrial plant of alkyl naphthalene Pour Point Depressant was built, and the systematic development and research began in the late 1950s. From 1963 to 1965, the industrial units of petroleum sulfonate salt detergent and Zinc Dialkyl Dithiophosphate Corrosion Inhibitor ZDDP were built one after another in China, so that the main additives used in internal combustion engine oil began to be based in China in the 1970s. Two detergent, thiophosphate polyisobutene barium salt and alkyl salicylate, poly alpha olefin Pour Point Depressant, polyisobutylene and polymethacrylate Viscosity Index Improver, Phenolic Antioxidant, etc., were produced respectively. In addition, a number of Rust Preventative Anti-rust Additive, such as barium petroleum sulfonate, barium diazenesulfonic acid salt, dodecenyl su
Performance of Emulsifier And Anti-Emulsifier
2019 / 09 / 29
Following is a discussion of the following issues: performance and scope of application of anti-emulsifiers and emulsifiers. Emulsifier is a kind of substance which can improve the surface tension of various constituent phases in the emulsion and make it form a uniform and stable dispersion system or emulsion. Emulsifier is a surfactant with hydrophilic and lipophilic groups in the molecule. It gathers at the oil/water interface, which can reduce the interfacial tension and reduce the energy needed to form the emulsion, thereby increasing the energy of the emulsion. Lubricating oil will lose its fluidity emulsifier can double the viscosity of oil) and lubricity after emulsification or its poor anti-emulsifying property. It will also cause metal corrosion and wear. Industrial gear oil, steam turbine oil and hydraulic oil (such as oil containing zinc salt) are vulnerable to water pollution, so these oils have higher requirements for anti-emulsification performance. Characteristics of emulsifiers and emulsifiers:
The difference between synthetic lubricant oil and mineral lubricant oil
2019 / 09 / 28
There is a basic important question: what is the difference between synthetic lubricant and mineral lubricant? Let us discuss it together as below. A lubricant is said to be mineral when its main component, the base oil are coming from the refining of crude oil. Crude oil is being extracted from the ground at various locations across the globe. Crude oil is a fossil fuel and is made of various different components in a ratio that will vary from its geographical origin. One component of crude oil is mineral oil used for lubricants.
Development Prospect of Lubricating Oil Additives in China
2019 / 09 / 28
The concept of lubricant oil additive is to add one or more compounds to lubricants in order to obtain some new properties of lubricants or to improve some of the existing properties of lubricants. Additives are mainly divided into functional categories, such as High Temperature Antioxidants, Antiwear EP Additive, friction modifiers, extreme pressure additives, Antifoam Additive Package, Rust Preventative Anti-rust Additive, Gear Oil Additive Package, PCMO Gasoline Engine Oil Additive Package and so on. In recent years, the good growth of China's automotive industry has made China the world's largest market for lubricant additives. With the continuous progress of domestic additive technology, some domestic additive products can compete with foreign additives in domestic and foreign markets. According to statistics, the domestic output of lubricant additives in 2017 is 641.2 million tons, and the domestic output of lubricant additives in 2018 is increased to 669 million tons. The main additives in China are comparable to those in other countries, but there is still a gap in product quality, and high-end products still need to be imported. In China, lubricant oil additives are widely used in transportation, construction machinery, metallurgy, mining, machine tools, special operations and other fields. Transportation is the most widely used market. With the gradual enhancement of environmental protection awareness in China,
70 Years Butterfly Change: China's Lubricants Grow Together with China
2019 / 09 / 27

At present, china can produce single additive(Calcium Alkyl Phenate, Ashless Dispersant, Pour Point Depressant etc. )and additive package(PCMO Gasoline Engine Oil Additive Package, HDEO Diesel Engine Oil Additive Package, Gear Oil Addtive Package etc.). Before the Daqing Oilfield was discoveried, China wore the cap of "oil-poor country" and Limited car ownership. The whole petrochemical industry is made up of scattered workshop-type small factories, and there is no way to start with the scale and systematization. A favourable appeared in the late 1950s. China's newly launched space launch vehicles and strategic nuclear weapons vehicles urgently needed reliable special lubricants as a guarantee. At that time, only a handful of countries mastered the manufacturing technology of space fluoride oil. In 1958, the predecessor of Sinopec Great Wall Lubricating Oil Company, No. 621 Factory, was established. The first task was to develop perfluorocarbon oil for China's nuclear industry and ensure the development progress of national strategic weapons.
Brief Introduction of Lubricant Additive Amine and Phenol High Temperature Antioxidant
2019 / 09 / 26
1. AMINE AND PHENOL-BEARING COMPOUNDS Given the high popularity and effectiveness of amine and phenol derivatives as lubricant anti oxidants, the combination of amine and phenolic moieties in one molecule represents a logic approach to enhance performance. In a prior art, fusing amine with a long carbon chain 3,5- di-tert-butyl-4-hydroxyphenalkyl group that separates the phenol group from the amino nitrogen leads to novel products with lower volatility, better thermal stability, and higher solubility in oils. Nelson and Rudnick reacted an ethyoxylated alkyl phenol with an alkyl arylamine in the presence of an aldehyde. The resulting product had improved antioxidant potency owing to a syn ergistic action between the phenolic moiety and the amine, and also showed enhanced solubility in oils owing to the presence of alkylated aromatic moiety in the molecule. Phenolic imidazo lines have been prepared from polyaminophenols and carbonyl compounds. In addition to providing antioxidant activity, the products also have corrosion inhibition and metal deactivation properties owing to the cyclic imidazoline moiety. Multifunctional additives containing sulfur, nitrogen, and phenolic moieties in one molecule have been reported. In this instance, mercaptoben

The Introduce of Lubricating Oil additive
2019 / 09 / 16
As a professional manufacturer & supplier of Lubricant Additive for years, We want to introduce the Lubricant Additive. Today we are mainly to introduce the Detergent,Detergent is one of the five additives of modern lubricants,In the past, detergents and dispersants were collectively referred to as detergents dispersants.In order to distinguish them, if including metal is called a ash detergent dispersant,if don't including metal is called Ashless detergent dispersant.At present, some literature refers to these two as deposit control additives.and the role of detergent and dispersants in lubricants is still different, therefore, after the 1970s, the clean dispersants are called detergents and dispersant two varieties. In the 1930s, due to the development of diesel engine to high power, there were problems such as increased carbon accumulation and sticky ring of piston ring grooves. The Detergent have evolved from fatty acids and cycloalic soaps to today's Sulfonates, alkylphenates , and Sulfurized alkyphenates, Phosphonothiolate, alkylsalicylates,Naphthena tes and other varieties. These five types of detergents were initially used with neutral salts. At the end of the 40th and early 50's, along with the increasing number of high-power supercharged diesel engines and the increase of sulfur-containing fuels, and Understanding and Understanding of the Role of Neutralization , all kinds of detergent began to develop in the direction of alkaline salt or high alkaline salt, and the amount of highly alkaline products in all kinds of detergent agents accounted for the majority. Our main products include: Additive Component
