Since middle March, international oil prices have continued to rebound. As of the close on April 13th, US WTI crude oil futures have risen to $83.09 per barrel, setting a record for the highest closing price this year. The fluctuation of crude oil prices directly affects the downstream industry chain, and the expectation of tight oil supply is bound to drive up the market of downstream petroleum products, including lubricants. In fact, lubricant companies have recently started a price adjustment model. Expert analysis suggests that due to multiple factors such as rising oil prices, rising costs, and continuous maintenance of refineries, there is still a demand for further increases in lubricant prices. Major lubricant companies are raising prices one after another From February to early April this year, major domestic and foreign lubricant companies have completed a wave of price increases. Starting from April 1st, Sinopec Lubricants Company will raise the price of Great Wall Lubricant, with a price increase of over 8% for main sales of passenger car oil and an increase of 400 yuan/ton for main sales of commercial vehicle oil. Castrol Lubricants also decided to adjust the prices of passenger car channel lubricant products and OEM lubricant products from April 1 by 5% - 10%. In addition to these two top lubricant companies, most brands in the lubricant market, such as Shell, Kunlun, SK, Shengpai, etc., have completed price adjustments, with the highest increase of 20% for SK lubricant.
Effect of Emulsion Index on Cold Rolled Sheet
2023 / 04 / 05
The emulsion mainly consists of base oil, emulsifiers, additives, and water. In addition to emulsifiers, the performance and content of other components also have a significant impact on the lubrication performance, usage effect, and service life of the emulsion. The main functions of emulsions include cooling, lubrication, rust prevention, etc., and their chemical properties have a certain impact on their functions. Its cooling function is mainly used to cool the rolled piece and roll, reduce deformation of the rolled piece, improve flatness accuracy, extend roll life, and thereby improve rolling speed and reduction, and improve productivity. Various lubricant additives, such as fatty acid oil, amide esters, polymers, etc., are added to existing emulsions, which can play a role in rolling lubrication, effectively reduce the friction force between the roller and the workpiece, improve the accuracy and surface finish of the product, and extend the service life of the roller. 1. The Effect of Emulsion Temperature on Rolling Force The use temperature of emulsion is also one of the main factors affecting rolling lubrication, and the temperature affects the size and spread of dispersed emulsion oil droplets. A low temperature may cause the emulsion to become rancid and grow bacteria, and low temperature is not conducive to the use of additives such as extreme pres
Process Cognition of Component and Additive Package in Lubricant
2023 / 03 / 26
Lubricant additives are generally divided into two categories: component and additive package. The component part includes: detergents, ashless dispersants, oxygen and corrosion resistant additives, antioxidants, rust inhibitors, pour point depressants and antifoam additives; Additive Package: engine oil additive package, gear oil additive package, hydraulic oil additive package, metal working oil additive package, other additive package, etc. In response to this change in market demand, product quality upgrades and product structure updates, advantageous products emerge in endlessly. For example, detergent products have good detergency, strong acid neutralization ability, low foaming tendency, low viscosity, low turbidity, and low chroma. They have excellent compatibility with base oils and compatibility with other additives. The ashless dispersant series is mainly composed of polyisobutylene succinimide, with the advantages of good dispersion, environmental protection, and low consumption; The anti oxygen and anti corrosion agent series mainly con
Evolution of green cutting lubrication technology
2023 / 03 / 14
Purpose of cutting fluid During the cutting process, high temperature and high pressure are produced at the cutting part due to severe friction, which seriously affects the service life of the tool, the precision and surface finish of the machined part. There are two main measures to reduce temperature, reduce friction, ensure tool life and workpiece accuracy: (1) Reduce friction during cutting and reduce tool wear; (2) Take away the high temperature gathered in the cutting part in time. The traditional lubrication method is to spray cutting fluid to the machining point. According to experience, the greater the supply of cutting fluid, the better the effect. In the past few years, "high pressure cooling" was actively promoted in the field of cutting. For a time, a large supply of cutting fluid was regarded as the "savior" of cutting. Hazards of using cutting fluid Since the 20th century, the machinery manufacturing industry has undergone new changes: (1) The world has paid extensive
What is the acceptable standard of turbine lubricating oil particle size?
2023 / 03 / 14
Oil particle size is an objective measure of the particle size in petroleum products. It reflects the distribution, size and quantity of particles in the oil. There are standards to follow: NAS1638, ISO4406, GJB420, GJB380. 1. The concept of particle size. The particle size refers to the number and concentration of solid particles with different particle sizes in the unit volume of oil, with the unit of pieces/100 ml. It is measured with a special particle size meter. Particle size is an important standard to judge whether turbine lubricating oil is qualified. It is generally believed that when people can't see the oil without particles, that is, the oil is not polluted. In fact, it is less than 40 μ Particles below m are invisible to the naked eye, and are more than 40 μ M Smaller particles have disastrous effects on hydraulic components or bearings, and often these small particles play a key role in the wear process. 2. Reasons for unqualified particle size in turbine lubricating oil. 1) Contaminants left by lubricating oil system components during manufacturing, assembly and overhaul. Such as hair, iron filings, welding slag, dust, etc. These pollutants were not cleaned timely and thoroughly during unit installation and flushing. 2) The oil enters
The secret of ensuring the best use of cutting fluid and effectively extending its service life
2023 / 02 / 26
1. Reasonable use of cutting fluid Reasonable use of metal cutting fluid can effectively reduce cutting force, cutting temperature and thermal deformation of the processing system, which can not only ensure the processing quality of the workpiece, but also extend the tool life and reduce the processing cost. The main functions of metal cutting fluid in mechanical removal are cooling, lubrication, cleaning and rust prevention. The effect of cutting fluid depends not only on the various properties of the cutting fluid itself, but also on the processing requirements, workpiece materials, tool materials, processing methods and other factors, which should be comprehensively considered, reasonably selected and correctly used. (1) Select according to processing requirements During rough machining, a large amount of cutting heat is generated due to large cutting amount. In order to reduce the cutting temperature, water-based cutting fluid with good cooling performance should be selected at this time. During finishing, the workpiece is required to obtain the best surface quality and smaller surface roughness value, so cutting oil should be used. (2) Corresponding to different processing methods In conte
How to choose lubricant for normal temperature chain and high temperature chain?
2023 / 02 / 16
What are the requirements for selecting lubricant for normal temperature chain? Basically, the lubricant used for the chain should meet the following two requirements: 1. Basic requirements: be able to cope with slow oscillation motion/high frequency pressure and oscillation load; The wear caused by mixed friction and boundary friction., 2. On the premise of sufficient budget, the lubricant is required to have good permeability, adhesion and anti-wear effect. Why should we meet the above two requirements? That is because: the anti-wear effect is good, which can maximize the service life of the chain. With good permeability and adhesion, the oil can reach the friction part in the chain link, allowing the chain to obtain continuous lubrication supply. The frequency of oil pumping will be reduced; The dosage will decrease naturally. How to choose lubricant for high-temperature chain? The working condition of high-temperature chain is more severe than that of normal-temperature chain, so the requirements for lubricant selection are hig
Principle system of cutting fluid formula
2023 / 02 / 02
1. Classification of cutting fluids Water-based cutting fluid can be divided into emulsion, semi-synthetic cutting fluid and fully synthetic cutting fluid. The classification of emulsion, semi-synthetic and fully synthetic usually depends on the type of base oil in the product: emulsion is a water-soluble cutting fluid that only uses mineral oil as the base oil; Semi-synthetic cutting fluid is a water-soluble cutting fluid containing both mineral oil and chemically synthesized base oil; Fully synthetic cutting fluid is a water-soluble cutting fluid that only uses chemically synthetic base oil (i.e., mineral oil). Each type of cutting fluid will contain various additives other than base oil: antirust agent, non-ferrous metal corrosion passivator, defoamer, etc. Some manufacturers will classify micro lotion; It is generally considered to be between emulsion and semi-synthetic cutting fluid. The diluent of the emulsion is milky white in appearance; The diluent of semi-synthetic solution is usually translucent, and some products are milky white; The diluent of the total synthetic solution is usually completely transparent, such as water or slightly colored.
What additives should be used for a good hydraulic oil?
2022 / 12 / 26
With the development of hydraulic technology, the requirements for hydraulic fluid are getting higher and higher. The performance of base fluid itself is far from meeting the requirements of hydraulic system. It is necessary to improve the performance of base fluid by adding various additives. At present, almost all the fluids used in hydraulic systems contain additives with various functions. The additives of hydraulic fluid can be roughly divided into two categories: one is to improve the physical properties of the fluid, such as oily agent, tackifier, anti foaming agent and pour point depressant. The other is additives to improve the chemical properties of oil, such as antioxidants, rust inhibitors, mold inhibitors, demulsifiers and metal passivators. 1. Oiliness Additive Oily agent is a kind of substance with strong polarity. Under low temperature and pressure, it can adsorb with metal surface to form a firm adsorption film, prevent metal from direct contact, improve oil film strength, and reduce metal friction and wear. In hydraulic fluid, commonly used oily agents include oleic acid, sulfurized whale oil (T401), sulfurized cottonseed oil (T404), sulfurized olefin cottonseed oil (T405), dimeric acid (T402), etc. 2. An
How to select cutting fluid correctly for 10 different types of cutting processes?
2022 / 12 / 05
Whether the selection of cutting fluid is reasonable and the problem of cooling and temperature control will greatly affect the processing efficiency and even the quality of finished products. First of all, for different types of cutting, the metal removal characteristics are completely different, and the higher difficulty of cutting will also require higher cutting fluid. The sequence of cutting process from difficult to easy is: internal broaching, external broaching, tapping, thread processing, hobbing, deep hole drilling, boring, forming tool cutting thread, high-speed low feed thread cutting, milling, drilling, planing, single edge tool turning, sawing and grinding. Today we will see how to select the corresponding cutting fluid for 10 different machining methods! 1. Turning & boring 1.1 Rough turning During rough turning, the machining allowance is large, so the cutting depth and feed are large. The cutting resistance is large, a lot of cutting heat is generated, and the tool wear is also serious. Therefore, water-based cutting fluid mainly used for cooling, cleaning, lubrication and rust prevention is mainly selected to take away cutting heat in time, reduce cutting temperature and improve tool durability. In general, it is better to select extreme pressure emulsion. In addition to good cooling performance, it also has good extreme pressure lubrication, which can
How to conduct depth inspection on ferrous metal water-based rust inhibitor?
2022 / 12 / 05
Ferrous metal water-based rust inhibitor is generally composed of corrosion inhibitor, complexing agent, alkali, wetting agent, etc. The substance that plays a key role in the rust prevention process is a corrosion inhibitor. Different inhibitors have different corrosion inhibition mechanisms. Different corrosion inhibitors have different antirust properties. Common inorganic corrosion inhibitors include sodium nitrite, sodium molybdate, sodium tungstate, boric acid, borax, phosphate, etc. They are all anodic oxidation inhibitors. There are more kinds of organic corrosion inhibitors, such as the well-known carboxylic acid salts: mono carboxylic acid, dicarboxylic acid, ternary acid, etc. In addition, fatty acid amides, borate esters, petroleum sulfonates, alkyl succinic acids, cationic quaternary ammonium salts, etc. This kind of corrosion inhibitor contains nitrogen, phosphorus, sulfur, oxygen and other elements with lone pair electrons, which can directly form a chemical adsorption layer on the metal surface. It is a mixed corrosion inhibitor. Common complexing agents include EDTA, phosphate, etc. The amount and type of complexing agents have a great influence on the rust resistance. The complexing agent chelates with calcium and magnesium ions in water, while the corrosion inhibitor generates sodium salt
Solution to cutting oil smoke and adhesion problems
2022 / 11 / 14
1. Smoke problem The smoke problem is caused by physical reasons, that is, the oil mist escaping into the air due to high-pressure crushing atomization. There are also chemical reasons, that is, the boiling point temperature of pure cutting oil is too low, the temperature in the processing area is close to the initial boiling point, and the cutting oil changes chemically when heated, producing smoke. The root cause of the problem is that the chemical causes are not easy to solve, which is also the most harmful. Improve the refining degree of cutting pure oil base oil and increase the initial boiling point. The higher the boiling point on the apparent physical and chemical indicators, the less likely it is to produce smoke. Cutting temperature is the root of generating oil vapor smoke. From the perspective of temperature control, there are two paths: controlling accumulated temperature and strengthening heat dissipation. Fundamentally, improving the ability of extreme pressure lubrication can delay the accumulated temperature reaching the boiling point range of cutting oil. From experience, the extreme pressure capacity is increased by 5%. Under the proper liquid supply pressure, the cutting temperature can be lowered by more than 30 degrees, which can significantly reduce cutting smoke. 2. Adhesion problem
Formula characteristics of industrial gear oil
2022 / 11 / 07
Industrial gear oil is widely used in steel, cement, coal, petrochemical and many other industries. With the rapid development of the national economy, its consumption is increasing year by year. In 2020, the domestic demand has reached 310000 t/a. According to the requirements of GB5903-2011, 16 physical and chemical indexes and bench performance of industrial gear oil, including kinematic viscosity, liquid phase corrosion, oxidation stability, four ball extreme pressure and anti-wear, and FZG bearing capacity, shall be tested before delivery. Some of the test items have a long period (for example, oxidation takes 13d) and high cost (FZG is 20000 yuan/time), which results in many oil batch test items, high test cost and delayed delivery, which is not conducive to timely supply to customers. If the factory batch inspection items are reasonably simplified according to the industrial gear oil formula and product performance characteristics, it can effectively avoid repeated waste and help the market to ensure supply. Characteristics of gear oil formula Industrial gear oil is developed according to the characteristics of gear box working conditions. It is generally required to have appropriate viscosity, good viscosity temperature performance, sufficient extreme pressure and anti-wear performance, good oxidation stability, anti emulsification performance, anti foam performance, rust prevention and corrosion resistance, etc., mainly involving extreme pressure agent, anti-wear agent, friction improver, pour point depressant, antioxidant, rust inhibitor, copper corrosion inhibitor, demulsifier, anti foam agent and other additives. According to the main role of additives
How are the quality inspection items of cutting oil and water-based cutting fluid different?
2022 / 11 / 02
The main quality control indicators of cutting oil include viscosity, flash point, pour point, fat content, sulfur content, chlorine content, copper strip corrosion, water, mechanical impurities, four ball test, etc. Water based cutting fluid shall be diluted with water when it is used, and its test items can also be divided into direct measurement and water measurement. The items directly measured include storage stability, sulfur and chlorine content, nonvolatile components, etc. The items to be measured after adding water include surface tension, pH value, foaming property, rust resistance, corrosivity, adaptability to paint, allowable amount of salt, antibacterial property, etc. The significance of most of these projects is relatively clear. Quality inspection items of cutting oil Fat content Fat is an oily additive in cutting oil and an important index to classify cutting oil. Fat in cutting oil can play a role in reducing friction coefficient and tool wear (especially effective in preventing tool flank wear). The cutting oil with more fat is especially suitable for nonferrous metal processing and the occasions where the cutting amount is small but the product precision and finish requirements are high (such as fine turning thread). Generally, saponific
How can we simply judge the performance and quality difference of different cutting fluids
2022 / 11 / 01
How can we simply judge the performance and quality difference of different cutting fluids in daily use? Even if we are in the factory, we can compare the main performance indicators of different cutting fluid products in the simplest way. You only need to spend 5 minutes, which may save at least 10% of the cost! 1) Cutting fluid performance The longer the tool life and the better the surface finish, the better the cutting fluid lubrication performance. In the case of the same equipment, the same tool and processing the same workpiece, compare the tool life (number of parts that can be processed by a single tool or cutting distance) and processing quality (surface finish). Lubrication performance is a very important index of cutting fluid. It directly affects the processing quality and cost. However, it is impossible to judge intuitively, because you cannot know the formula of cutting fluid and the effective lubricating composition. 2) Stability Delamination, impurities and non-uniformity are found in any of the following two items. It can be determined that the cutti
Development and application prospect of synthetic industrial gear oil
2022 / 09 / 29
Development trend of industrial gear oil: the improvement of gear box manufacturing technology and the specification evolution of industrial gear oil are two major factors affecting the development trend of industrial gear oil. 1. Development of Industrial Gear Equipment With the rapid development of the gear industry, the industrial gearbox is developing towards greater power, higher load and smaller volume, and the working environment is humid. The increase of the load increases the contact pressure of the tooth surface and the wear and pitting between metals; The reduction of gearbox volume means that there is less oil for lubricating gears and bearings, which will lead to the increase of oil temperature and accelerate the oxidation of oil. The sludge generated in the oxidation process will shorten the service life of oil and gearbox components; 2. Evolution of Industrial Gear Oil Specifications AIST 224 standard has always represented the highest specification of industrial gear oil, and the quality of L-CKD gear oil in the national standard GB 5903-2011 Industrial Closed Gear Oil formulated in China has reached this standard. In addition, the commonly used industrial gear oil specifications include the national standard ISO 12925, AGMA 9005-E02 EP in North America, and DIN51517-3 in Europe. From the above development of industrial gear manufacturing and industrial gear oil specifications, the future industrial gear oil should not only have good tribological properties, but also meet the r
Characteristics of Modern Cutting Fluids
2022 / 09 / 29
With the rapid development of modern machinery manufacturing industry, the continuous innovation of cutting technology and cutting process has put forward higher requirements for the performance of cutting fluid. Especially in recent years, environmental protection and human health have increasingly become the focus of attention of the whole society, and cutting fluid will cause pollution and damage to the environment and human body, so the use of cutting fluid and waste liquid treatment have been increasingly restricted by environmental regulations. In developed industrial countries, the amount of smoke generated during machining with cutting fluid is also strictly limited. Some cutting fluid waste liquid and chips with cutting fluid are required to be treated as toxic materials, and the cost of treatment is increasing. In order to meet the requirements of social development, some new features have emerged in the development of modern cutting fluid technology. 1. Development of cutting fluid with high performance, long life and low pollution and research on waste liquid treatment technology In recent years, China has imported more and more advanced manufacturing equipment such as CNC machine tools and machining centers. If the required cutting fluid is imported for a long time, the production cost will rise significantly due to the high price. Therefore, it is urgent to develop high-performance cutting fluid to replace imported products. At present, water-based cutti
How to reduce equipment lubrication failure prevention monitoring is very important
2022 / 09 / 25
Equipment lubrication management is one of the basic contents of equipment management. The level of equipment lubrication management can reflect the level of enterprise equipment management and the civilization level of on-site management from one side, and it is also directly related to the safety and economic and technical indicators of equipment operation. How to do well in equipment lubrication is an important part of equipment management. Preventive measures for lubrication failure 1. Guide rail: to ensure good lubrication of the guide rail, the following should be done: ensure the processing accuracy of the guide rail and the contact area of the dynamic and static guide rails; The shape and size of the lubricating groove shall be correctly selected, and the position of the oil inlet hole shall be reasonably arranged. The appropriate guide oil shall be selected according to the load, movement speed, guide rail layout, etc. 2. Gear: the working characteristics of general gears are high contact stress and low speed, and it is difficult to form fluid lubricating film in the meshing area. The lubrication state of the tooth surface is mainly boundary lubrication and mixed lubrication. The tooth surface is mainly damaged by adhesive wear (gluing), fatigue pitting and abrasive wear. The lubrication is mainly
How will the grease market trend in 2022?
2022 / 09 / 04
The grease market is extremely fragmented, with a total capacity increase of approximately 6.25 million tons in 2022. At present, the overall trend of the market is stable, and the market demand is bound to grow further. In the future, the lubricating grease market will have obvious aggregation phenomenon. The following is an analysis of the lubricating grease industry market. The 2022-2027 China synthetic grease industry market demand and investment consulting report pointed out that the bidding volume of various lubricants in 2022 has dropped sharply since January, and the decline of each product is about 25-45%. The sum of the data from January to May shows that hydraulic oil decreased by 18% year-on-year, gear oil decreased by 25% year-on-year, other industrial oils decreased by 45% year-on-year, grease decreased by 45% year-on-year, and antifreeze increased by 162% year-on-year.

The history and future development trend of cutting fluid in China
2022 / 09 / 04
The development of cutting fluid is basically a type of fine chemical product that was born and developed with the development of metal processing tools (ie machine tools) and processing technology. Its main function is to cool the workpiece and tools during the machining process. To prevent rust of workpieces and machine tools, rinse metal chips and other impurities. In the 1950s and 1960s, China was basically a manual rocker type machine tool, with low processing efficiency, low difficulty and poor precision. The quality of its products mainly depended on the technical level and experience of the workers. The requirements are very low. Generally, the factory has special personnel to prepare some low-grade cutting fluids with some chemical raw materials such as nitrite and alcohol amine. This type of cutting fluid is mainly used for cooling and rust prevention. For products processed under high lubrication conditions, people generally use saponified oil to solve the problem, which basically met the production requirements at that time. With the deepening of China's reform and opening up, by the early 1980s, China had made great progress in the field of machining, and introduced a large number of advanced production technologies and equipment from abroad, the most important of which was the introduction of CNC machine tools. On the one hand, the use of CNC machine tools not only speeds up the production speed, but also ensures the reliability and consistency of product quality. However, the rapid processing state of CNC machine tools cannot meet the processing requirements for ordinary traditional original cutting fluids, such as high-speed operation. The cutting speed of the cuttin

2022 / 07 / 31
The structure of the automobile chassis is compact and complex. There are about 20 to 40 different parts of the chassis of trucks, trailers, buses, construction machinery and equipment, cranes, forklifts, combine harvesters and some forklifts that need to be lubricated frequently. friction work. The lubrication of the chassis is very important to ensure the normal operation of the vehicle. If the lubrication is not good, it will cause damage and failure of the parts and affect the technical condition of the vehicle. The grease for automobile chassis varies according to the structure and characteristics of the mechanical parts and the requirements for grease and other working conditions. The following is a brief sharing of the performance requirements of lubricating greases according to the lubrication parts. 01. Clutch The clutch pedal, clutch release fork, and brake pedal bearings all require grease lubrication. The clutch bearing moves periodically and is easily polluted by external water and dust. It needs good extreme pressure and water resistance, and the clutch in the high temperature part also needs to have good high temperature resistance. The structure of the clutch is special, and it is difficult to grease the release bearing after loading. Burnout of clutch release bearing is mainly caused by poor lubrication.

What should I do if the anti-rust oil precipitates?
2022 / 06 / 26
Why does precipitation occur during the use of anti-rust oil? There is also a reason for this. Anti-rust oil manufacturers When using anti-rust oil, how to prevent the occurrence of anti-rust oil precipitation, and how to deal with the precipitation of anti-rust oil? 1) Precipitation phenomenon of anti-rust oil Antirust oil precipitation refers to the phenomenon in which the antirust oil sinks from its solid content to the bottom of the container during storage. When the precipitation of some anti-rust oils is serious, the solid components in the anti-rust oil are precipitated into dense lumps that are not easily redispersed by stirring methods, which is called anti-rust oil agglomeration. 2) Why does the anti-rust oil appear precipitation? In the process of production and processing, the dispersion is poor and the grinding is not fine. In the formulation of oil products, some reasons such as the excessive density of solid raw materials are prone to precipitation. Because too much diluent is added, the viscosity of the anti-rust oil is reduced, and the raw material of the anti-rust oil loses the suspended solids on the surface, resulting in precipitation. The materials undergo a certain chemical reaction or adsorption to each other, causing the gel to precipitate. Rust oi
The contact hazards and preventive measures of water-based cutting fluid must be kept in mind
2022 / 06 / 26
Workers engaged in cutting operations have many chances of prolonged contact with cutting fluid on hands, wrists, etc. during operation, and sometimes dermatitis occurs. This is a tricky question. According to statistics, about 1/4 of people exposed to oil-based cutting fluids suffer from occupational dermatitis, folliculitis, acne (pimples and pustules caused by inflammation of the pores), pigmentation, keratoderma, and abscesses to varying degrees. From the phenomenon point of view, the symptoms caused by oil-based cutting fluid and water-based cutting are different. 1. Problems and incentives Dermatitis caused by water-based cutting fluids generally causes the skin to degrease, crack, and cause redness, swelling, and purulence. Its symptoms are similar to the rough hands of housewives who often use detergent. The main reasons are: 1) Degreasing effect of surfactants (resulting in reduced sebum secretion, insufficient sebum film formation, and dry and thick skin). 2) Alkaline damage caused by alkaline substances such as organic amines and inorganic bases. 3) Irritant damage caused by fungicides, preservatives, antifungal agents, etc.
