Fully synthetic cutting fluid is a water-soluble cutting fluid that uses only chemical synthetic base oil (i.e. does not contain mineral oil). Water has good heat transfer and cooling effects, but pure water can easily cause metals to rust and has poor lubrication properties. Therefore, sufficient additives are always added to the aqueous solution, such as rust-proof additives, surfactants, and oily additives, so that it has both excellent rust-proof properties and certain lubrication properties. When preparing the aqueous solution, pay attention to the water quality. If it is hard water, soften it. Semi-synthetic cutting fluid refers to a water-soluble cutting fluid containing both mineral oil and chemical synthetic base oil. It is also called micro-emulsified cutting fluid. Its concentrate consists of a small amount of mineral oil (content is 5%-30%), oiliness agent, extreme pressure agent, rust inhibitor, surfactant and preservative. The diameter of the diluent oil droplet is less than 1μm, and the diluent is transparent or translucent. It has good cooling, lubrication and rust prevention properties. It has the advantages of emulsion and synthetic cutting fluid, and makes up for each other's shortcomings. It is the trend of cutting fluid development. Comparing semi-synthetic cutting fluid and fully synthetic cutting fluid, they have the following differences between them: 1. Semi-synthetic cutting fluid has relatively poor lubrication performance and poor processing results. Fully synthetic cutting fluid does not contain mineral oil substances and has many advantages such as long service life, cooling, cleanability, stability, etc. Semi-synthetic cutting fluid, because oil-soluble lubricating additives are difficult to add, results in weak lubricity and is not practical for production and processing. Not very effective.

The basic components of metalworking fluids are summarized as consisting of base materials and various additives. Base materials refer to the main components or carriers of metalworking fluids, which are used to dissolve and mix various functional additives. Commonly used base materials include water, base oil, animal and vegetable oils, alcohol and chemical solvents. Functional additives include oiliness agents, extreme pressure agents (or EP agents), rust inhibitors, viscosity index improvers, emulsifiers, antioxidants, pour point depressants, antifoaming agents, smoke suppressants, preservatives and bactericides, etc.   Metalworking fluids are divided into two categories: cutting fluids and forming lubricants. According to the type of machine tool and the method of material removal, they can be divided into cutting fluids, grinding fluids, electroprocessing fluids and forming lubricants. Cutting fluid is a lubricating and cooling medium used to lubricate and cool workpieces and tools or abrasives during cutting. Reasonable selection of cutting fluid can effectively reduce friction during cutting, improve heat dissipation conditions, reduce cutting force and cutting temperature, improve cutting efficiency and tool durability, and ensure the surface quality of the workpiece. Synthetic cutting fluid is composed of various water-soluble additives and water, and does not contain mineral oil. Its concentrate can be liquid, paste and solid powder, etc. When used, it is diluted with a certain proportion of water to form a transparent or translucent diluent, which has a long service life, excellent cooling and cleaning performance, and good anti-rust performance. It is suitable for grinding and cutting of steel, copper, aluminum and their alloys, and is also suitable for high-speed cutting. Since the synthetic fluid is transparent and has good visibility, it is particularly suitable for use in CNC mac

Common antiwear agents include sulfides, phosphides, etc. 3. Extreme pressure agent: Extreme pressure agent is an additive to reduce metal friction and is widely used in lubricating oils under high temperature, high pressure and heavy load conditions. It can form a protective film to effectively reduce the contact and wear of metal surfaces.   4. Improver: Improvers are mainly used to improve the fluidity and cleaning performance of lubricating oils. For example, dispersants can prevent precipitation and reduce the formation of sediments; detergents can remove dirt and sediments inside mechanical equipment.   5. Viscosity index improver: The viscosity index of lubricating oil refers to the ability of lubricating oil to change viscosity at different temperatures. Viscosity index improvers can keep lubricating oil at a relatively stable viscosity at different temperatures and improve lubrication performance.   6. Degassing

Differences in composition between ester oil and mineral oil 1. Ester oil Ester oil molecules contain COO and CH2 groups, as well as alcohol groups or epoxy groups. Due to the different combinations of these groups, ester oil has a variety of different chemical structures and properties. 2. Mineral oil The main components of mineral oil are hydrocarbons, including alkanes, cycloalkanes and aromatic hydrocarbons. Since these molecules are only connected by weak chemical bonds, petroleum molecules can easily react chemically to produce a variety of different products. Differences in physical and chemical properties between ester oil and mineral oil 1. Ester oil Ester oil generally has a lower melting point, which can reach -90℃, and is more suitable for use in low temperature environments than mineral oil. At the same time, because ester oil molecules contain polar groups, they are usually compatible with water and easily degraded. 2. Mineral oil Mineral oil usually has a higher melting point than ester oil, about -20℃ to -40℃. Since they are non-polar molecules, they usu

Corrosion inhibitor is a general term for inorganic and organic substances that have the function of inhibiting metal corrosion. Its function is to slow down the corrosion of metals during pickling, ensuring that the metal being cleaned is not corroded and damaged by the acid solution while pickling and descaling. Corrosion inhibitors are chemical substances that can reduce the corrosion rate of metals. They can achieve corrosion inhibition in a variety of ways. Generally speaking, corrosion inhibitors extend the service life of metals in the following ways:   1. Reduce surface potential   Corrosion inhibitors can reduce the potential of the metal surface and reduce the possibility of metal contact with electrolytes, thereby reducing the corrosion rate of metals.   2. Form a protective film   Corrosion inhibitors can form a protective film on the metal surface to resist corrosive substances and reduce the possibility of oxidation of the metal surface.   3. Hinder chemical reactions   Corrosion inhibitors can slow down the oxidation rate of metals by hindering chemical reactions, playing a role in corrosion prevention. Corrosion inhibitors are widely used in various fields, among which the most common application areas include:   1. Petroleum industry   During the process of oil drilling and transportation, corrosion inhibitors can slow down the rate of metal corrosion and oxidation, reduce the frequency of equipment maintenance and replacement, and save costs.   2. Automobile manufacturing and maintenance   Corrosi

In the metal processing industry, cutting fluid, as a key auxiliary material, plays a vital role in processing accuracy, tool life and workpiece quality. However, when processing aluminum and non-ferrous metals, improper use of cutting fluid often leads to oxidation and discoloration of the workpiece, seriously affecting product quality.How to solve the problem of oxidation discoloration of workpieces processed by cutting fluid 1. Choose the right cutting fluid: Choose a cutting fluid with excellent antioxidant properties according to the processing materials (such as aluminum and non-ferrous metals) and processing requirements. 2. Regularly test and adjust the pH value: Use instruments such as an acidometer to regularly test the pH value of the cutting fluid to ensure that it is within the normal range (6.5-8.5). If the pH value is found to be high or low, add an appropriate amount of regulator in time to adjust it. 3. Strengthen the cleaning and maintenance of the cutting fluid: Regularly replace the cutting fluid and keep the water tank and cutting fluid clean. Additives with antibacterial properties can be used to extend the service life of the cutting fluid. 4. Stabilize the cutting fluid formula system: Choose a cutting fluid formula that has been optimized to ensure that it can maintain stable performance under various working conditions. At the same time, pay attention to the compatibility of the various components of the cutting fluid. 5. Ensure that the cutting fluid contains sufficient aluminum slow-release agent: When selecting a cutting fluid, pay attention to whether it contains enough aluminum slow-release agent and keep its content stable during use. 6. Regularly test the concentration and pH value of the cutting fluid: Use instruments such as refract

Lubricating oil is the "golden blood" of mechanical equipment, playing the role of lubrication, cooling, rust prevention, cleaning, sealing and buffering. Lubricating oil is generally composed of two parts: base oil and additives. Base oil is the main component of lubricating oil and determines the basic properties of lubricating oil. Additives are an important part of lubricating oil, which can make up for the deficiencies in the performance of base oil, and are used to improve the performance of lubricating oil or give it some new characteristics. According to the different functions of additives, lubricating oil additives can be divided into antioxidants, anti-wear agents, friction modifiers (also known as oiliness agents), extreme pressure additives, detergents, dispersants, foam inhibitors, anti-corrosion and anti-rust agents, anti-emulsifiers, viscosity index improvers and other types. Today we focus onRust Preventative Anti-rust Additive . Adding anti-corrosion and rust-proof agents to lubricating oil can form a protective film on the metal surface, preventing oxygen in the air from oxidizing the metal surface, and preventing the metal surface from being corroded by water, acids, alkalis and other chemicals. It can effectively extend the service life of lubricating oil, improve lubrication effect and reduce maintenance costs.   The role of anti-rust additives in lubricating oil is to prevent metal parts from rusting and ensure the normal operation of the engine.   Rust inhibitors, also known as corrosion inhibitors, are an important additive in lubricating oils. Their main function is to prevent rust caused by oxidation during the use of lubricating oils, thereby extending the service life of lubricating oils. This additive can

In order to reduce energy consumption and CO2 emissions, the energy efficiency of mechanical systems must be improved, and an important way to achieve this goal is to develop lubricants that can produce low friction in machine parts. One way is to optimize the rheology of liquid lubricants to minimize hydrodynamic shear, stirring and pumping losses. In practice, this usually means reducing the lubricant viscosity as much as possible. Another way is to add a small amount of Friction Modifier to the lubricant to reduce friction in boundary lubrication and mixed lubrication. In practice, it is best to use both methods at the same time, because as the viscosity of the lubricant gradually decreases, the contact points rely only on thinner and thinner friction films, so more and more Friction Modifiers must be used. Generally speaking, there are several types of friction modifier additives: organic Friction Improver, functionalized polymers, soluble organic molybdenum additives dispersed nanoparticles. The lubricant industry has had to evolve to meet the stringent requirements of the growing transportation technology. For example, from simple wear reduction to heat transfer media in cast iron machines. Lubricants are also expected to act as high temperature antioxidants and protective coatings for modern internal combustion engines. Two common ingredients in industrial lubricants today are viscosity and friction modifiers, which work to improve operating efficiency and reduce wear. Friction modifiers (FM) reduce energy losses caused by internal friction and maintain boundary films to prevent wear. Although the base oil can reduce some boundary friction, it is not considered a true FM. Additional additives, including polymers are often used to reduce friction. However, polymer additives have poor shear stability.

High temperature antioxidants are a class of chemicals that can effectively prevent or slow down the oxidation degradation of materials under high temperature conditions. They are widely used in the production of plastics, rubber, oils, resins and other materials to improve the heat resistance, weather resistance and service life of these materials High temperature resistance: High temperature antioxidants can maintain stable antioxidant properties under high temperature conditions and effectively prevent the oxidation degradation of materials under high temperature. High efficiency: This type of antioxidant can quickly capture free radicals and interrupt the oxidation chain reaction, thereby significantly improving the antioxidant properties of the material. Wide applicability: High temperature antioxidants are suitable for a variety of materials, such as plastics, rubber, oils, resins, etc., and can meet the needs of different fields. High temperature resistant antioxidants are widely used in plastics, rubber, synthetic fibers, lubricants, fuel oils, food packaging materials and other fields. In plastic processing, they can improve the heat resistance, weather resistance and processing stability of plastics; in rubber products, they can extend the service life of rubber and prevent aging; in lubricants and fuel oils, they can inhibit the oxidation and deterioration of oil products and improve the performance of oil products. Adding antioxidants to lubricants can effectively extend the service life of oil products and maintain the normal operation of machinery and equipment. Antioxidants can resist oxidation reactions, protect oil products from oxidation, and thus slow down the aging of oil products. Antioxidants can also eliminate free radicals in lubricating oil and reduce the

Lubricating oil is an indispensable and important substance in industrial production. It plays the role of lubrication, friction reduction, cooling and sealing in mechanical equipment. However, bubbles are often generated during the production process, which will have a negative impact on the performance and stability of the lubricating oil. In order to solve this problem, anti-foaming agent is usually added during the production of lubricating oil. 1. Why do we need to add Anti-Foam when producing lubricating oil?   First of all, understanding the formation of bubbles in lubricating oil is the key to understanding the importance of adding Anti-foaming Agent. During the production process of lubricating oil, it is often subjected to violent stirring, high-speed stirring or operation under high temperature and high pressure conditions. During these processes, the air or other gases in the lubricating oil will be stirred to form a large number of bubbles. These bubbles will reduce the flow performance of the lubricating oil, and even prevent the lubricating oil from entering the friction surface of the equipment, affecting the lubrication   effect.2. What is the use of adding Anti-foaming Agent?   The addition of Anti-foaming Agent can effectively control the generation and stability of bubbles in lubricating oil. Defoaming agent is a special chemical substance that has the effect of reducing surface tension and viscosity. When defoaming agents are added to lubricating oil, they quickly diffuse to the surface of bubbles and change the physical properties of the bubble surface. In this way, the surface tension of bubbles is reduced, and the interaction force between bubbles is also reduced, so that the

Metal Working Fluid is an important and indispensable supporting material for mechanical processing. Its quality, level and quality directly affect the processing quality, production efficiency, energy consumption, material consumption and production environment of mechanical parts. The use of metal working fluid accounts for about the total amount of lubricating oil products, so both at home and abroad attach great importance to its development. Metal working fluids are divided into four types according to their form: oil, soluble oil, semi-synthetic fluid and synthetic fluid. The main ingredients of Water Soluble Cutting Fluid: oily additives and extreme pressure additives, anti-rust additives, anti-mildew additives, anti-foaming additives, and emulsifiers. Function: Cooling effect: When processing metal workpieces, the tool will generate friction with the metal workpiece, thereby generating high heat, causing deformation and damage to the workpiece; Lubricating effect: During the processing of metal workpieces, the friction between the tool and the workpiece surface will cause the tool and the metal workpiece to be scrapped; Cleaning effect: During the processing of metal workpieces, iron powder, grinding chips, oil stains and other dirt will be generated.

Water Soluble Fully Synthetic Cutting Fluid is an oily cutting fluid dispersed in water with a surfactant added. Water is used as a medium to reduce the temperature, oil is used as a lubricant, and the surfactant emulsifies the oil and water. Water-based cutting fluid is a relatively new, environmentally friendly, and non-toxic cutting fluid. Fully Synthetic Cutting Fluid is a fully oily cutting fluid. It is an older formula, but it is necessary for cutting certain workpieces. It is non-toxic The main difference between Water Soluble Fully Synthetic Cutting Fluid and Fully Synthetic Cutting Fluid lies in the type of base oil and the occasion of use. The base oil of water-soluble cutting fluid can be mineral oil or chemical synthetic base oil, while Fully Synthetic Cutting Fluid does not contain mineral oil at all and only uses chemical synthetic base oil. In addition, the dilution ratio of water-soluble cutting fluid is usually higher, while the dilution ratio of Fully Synthetic Cutting Fluid is lower, and the higher the concentration used, the better the lubrication and rust prevention performance.Water-soluble cutting fluid is suitable for various metal processing, including aluminum alloy, carbon steel, stainless steel and other materials. It has good cooling and lubrication properties and is suitable for various load processing. Fully Synthetic Cutting Fluid is mainly used for high-load processing, such as grinding and high-speed processing. It has good rust prevention and cooling properties, and is especially suitable for occasions requiring high-precision processing.

In the complex environment of lubrication systems, the existence and application of emulsifiers as a special additive brings both convenience and potential challenges.As a type of surfactant, the core feature of emulsifiers is the amphiphilicity of their molecular structure, that is, one end is hydrophilic (polar) and the other end is lipophilic (non-polar). This unique molecular structure enables emulsifiers to form a thin film on the oil-water interface, effectively reducing the interfacial tension between oil and water, and causing the two originally immiscible liquids to mix into a uniform emulsion. In lubricating oils, the role of emulsifiers is particularly critical. It can not only improve the dispersibility and stability of lubricating oils, but also achieve the stable existence of oil-water mixtures in certain specific application scenarios, such as wet clutches or certain systems that require water-based cooling, thereby optimizing system performance. The emulsification of lubricating oil has a significant negative impact on the performance and life of the equipment: 1. Reduced lubrication effect: The strength of the emulsified lubricating oil film is weakened, and it cannot effectively isolate the metal surface, resulting in increased friction and aggravated wear. 2. Accelerated corrosion: Water reacts with certain components in the lubricating oil, which may generate corrosive substances and accelerate the corrosion of metal parts inside the equipment. 3. Impact on heat dissipation: The thermal conductivity of the emulsion is worse than that of pure lubricating oil, resulting in a decrease in the heat dissipation efficiency of the equipment, which in turn affects the overall operating efficiency. 4. Oil contamination: The quality of th

Lubricant emulsifiers, as an indispensable chemical additi2024 09/06ve in modern industry, have shown significant technicaladvantages in the field of lubricants. Lubricant emulsifiers effectively combine the oil phase with the water phase to form a stable emulsion, which greatly improves the performance of lubricants and demonstrates its unique value in multiple industrial fields. 1. Characteristics of lubricating oil emulsifiers The core characteristics of lubricating oil emulsifiers are their strong emulsification ability and stability. Emulsifiers reduce the tension of the oil-water interface, allowing the oil-water mixture to form tiny droplets, thereby achieving uniform and stable emulsification. This characteristic enables lubricating oil emulsifiers to play an excellent role in lubricating oils, tightly combining the oil phase and the water phase to form a stable lubrication system. In addition, lubricating oil emulsifiers also have good lubrication performance and anti-wear and friction reduction properties. The stable emulsion formed by the emulsifier can better adhere to the friction surface, reduce friction a

In the process of metal processing and storage, the selection of anti-rust oil is very important. Solvent-dilutable anti-rust oil and displacement anti-rust oil are widely used due to their unique properties. There are significant differences in the use of additives in these two anti-rust oils, which directly affect their anti-rust effects and usage scenarios.Solvent-dilutable rust-proof oil, as the name implies, is rust-proof oil diluted by solvent. Its main feature is that it contains volatile petroleum solvents, which evaporate naturally when used at room temperature, thus forming a uniform protective film on the metal surface. The additives of this rust-proof oil mainly include two categories: hard film-forming materials and soft film-forming materials. Hard film-forming materials such as asphalt, resin (alkylphenol amino resin, tert-butylphenol methyl ester resin, petroleum resin, etc.), etc., will form a hard film on the metal surface after the solvent evaporates. This hard film is not sticky to the hands, dust and impurities, transparent or opaque, has good corrosion resistance, and can be easily washed off in petroleum solvents such as gasoline. However, its disadvantage is that it must wait for the solvent to completely evaporate before packaging or contact, otherwise it will cause the workpiece to stick. Therefore, hard film anti-rust oil is more suitable for rust prevention on the surface of large mechanical equipment, or for the sealing of raw materials and equipment stored in open air conditions. Unlike hard film-forming materials, soft film-forming materials are mainly composed of oils and fats, such as lanolin and its derivatives, wax, vaseline, oxidized petroleum grease and its barium soap. After the solvent evaporates, these materials form an oil film, namely a soft

In the field of modern metal processing, cutting fluid, as an indispensable auxiliary material, has a vital impact on processing quality, tool life and production efficiency. With the increasing awareness of environmental protection and increasingly stringent regulations, phosphorus-free cutting fluid, as a new type of green and environmentally friendly cutting fluid, has gradually gained favor in the market.Phosphorus-free cutting fluid, as the name implies, is a cutting fluid that does not contain phosphorus. Phosphorus is often used as a rust inhibitor and extreme pressure additive in traditional cutting fluids to improve the anti-rust performance and extreme pressure lubrication ability of cutting fluids. However, phosphorus causes great pollution to the environment, especially the eutrophication of water bodies, making the development and application of phosphorus-free cutting fluids an inevitable trend. Phosphorus-free cutting fluids achieve similar or even better performance than traditional cutting fluids by using new environmentally friendly additives such as synthetic fats, extreme pressure agents, rust inhibitors, fungicides, etc., while greatly reducing the negative impact on the environment. Characteristics of phosphorus-free cutting fluid 1. Environmentally friendly: The biggest feature of phosphorus-free cutting fluid is its environmental friendliness. It does not contain toxic and harmful substances such as phosphorus, nitrites, phenols, etc., has good biodegradability, reduces pollution to water bodies, and meets the requirements of modern industrial green development. 2. Superior performance: Although phosphorus-free, modern phosphorus-free cutting fluid can still maintain excellent lubricity, cooling, permeability and rust resistance through scientific formula design. During the cutting process, it can effectively reduce workpiece scratches and wear, increase cutting

The foam problem in water treatment has troubled many people, including the initial foam in debugging, surfactant foam, impact foam, peroxide foam, foam generated by adding non-oxidizing bactericides in circulating water treatment, etc. Therefore, the use of Anti-foaming Agent in water treatment is relatively common. This article comprehensively introduces the principle, classification, selection and dosage of Anti Foam! 01 Methods for eliminating foam 1. Physical methods From a physical point of view, the methods for eliminating foam mainly include placing baffles or filters, mechanical stirring, static electricity, freezing, heating, steam, radiation, high-speed centrifugation, pressurization and decompression, high-frequency vibration, instantaneous discharge and ultrasound (acoustic liquid control), etc. These methods promote the permeation rate of gas at both ends of the liquid film and the drainage of the bubble film to varying degrees, making the stability factor of the foam smaller than the attenuation factor, so that the amount of foam gradually decreases. However, the common disadvantages of these methods are that their use is strongly restricted by environmental factors and the defoaming rate is not high. The advantages are environmental protection and high reuse rate. 2. Chemical method The methods of eliminating foam from a chemical perspective mainly include chemical reaction method and adding defoaming agent method. The chemical reaction method refers to adding some reagents to react chemically with the foaming agent to generate water-insoluble substances, thereby reducing the concentration of surfactants in the liquid film and promoting the rupture of foam. However, this method has the disadvantages of uncertain composition of the foaming agent and the generation of insoluble substances that harm the system equipment. Nowadays, the most

Ashless dispersant is a type of substance that adjusts the performance of internal combustion engine oil. When used in combination with Oil Additive, it can more effectively prevent deposits formed by oxidation products during the use of internal combustion engine oil. The chemical structure of ashless dispersant is composed of lipophilic groups, polar groups and connecting parts. Such a chemical structure can easily form micelles in lubricating oil, ensuring that it has a strong solubilizing effect on liquid initial oxidation products, and has a good peptizing and dispersing effect on solid particles such as carbon deposits and soot, effectively ensuring the low-temperature dispersion performance of internal combustion engine oil, and especially effectively solving the low-temperature sludge problem of gasoline engine oil. When gasoline engine oil with dispersant is changed after running for a long time, the sludge in the crankcase is reduced, and the dispersing and solubilizing effect on soot and lubricating oil oxidation products generated by high-temperature oxidation is also improved. In particular, it has a synergistic effect when combined with metal detergents, which not only improves the quality of the lubricating oil, but also reduces the amount of Industrial Oil Additive added. What is the role of Ashless dispersants?   Solubilization: Some oxidation products are polymerized and mixed with condensed water to form engine sludge, which increases engine carbon deposits and adheres to the fuel tank to prevent the oil pump from sucking in, thereby clogging the filter. Succinimide dispersants can form micelles with carbon deposits and sludge that are insolub

Lubricating oil is an indispensable and important substance in industrial production. It plays the role of lubrication, friction reduction, cooling and sealing in mechanical equipment. However, bubbles are often generated during the production process, which will have a negative impact on the performance and stability of the lubricating oil. In order to solve this problem, defoaming agents are usually Antifoam Additive when producing lubricating oil. During the production process, lubricating oil is often subjected to violent stirring, high-speed agitation, or operation under high temperature and high pressure conditions. During these processes, air or other gases in the lubricating oil will be stirred to form a large number of bubbles. These bubbles will reduce the flow performance of the lubricating oil and even prevent the lubricating oil from entering the friction surface of the equipment, affecting the lubrication effect. The addition of defoamers can effectively control the generation and stability of bubbles in lubricating oil. Defoamers are special chemicals that have the effect of reducing surface tension and viscosity. When defoamers are added to lubricating oil, they quickly diffuse to the surface of bubbles and change the physical properties
