Deciding how to formulate a cutting oil emulsion?

In machining, the main functions of cutting oil are cooling, lubrication and cleaning. However, there are some problems during the use of traditional cutting oil, such as oil contamination, insufficient lubrication, etc. These problems may lead to equipment failure, tool wear and other problems. In order to solve these problems, we can formulate the cutting oil into an emulsion to improve its lubrication performance while having good cooling and cleaning effects.

In order to formulate a cutting oil emulsion, we need to follow these steps:

Select the appropriate cutting oil base oil. Cutting oil base oil should have good lubricity, cooling and corrosion resistance. Commonly used base oils include mineral oil, vegetable oil, etc.

Add emulsifier. Emulsifier is the core component of emulsion preparation. Its main function is to disperse the base oil in water to form a stable oil-in-water emulsion. Commonly used emulsifiers include soap, sodium petroleum sulfonate, etc.

Add antioxidants. Antioxidants can extend the service life of the emulsion and prevent the base oil from oxidative deterioration. Commonly used antioxidants include phenolic compounds, aromatic amines, etc.

Add extreme pressure agent. Extreme pressure agents can improve the extreme pressure lubrication properties of emulsions and reduce tool wear. Commonly used extreme pressure agents include sulfide, phosphide, etc.

Add rust inhibitor. Rust inhibitors can prevent workpieces and tools from rusting and improve the reliability of the machining process. Commonly used anti-rust agents include petroleum sulfonates, amides, etc.

Below we use a specific preparation case to illustrate the preparation process of cutting oil emulsion:

Select the appropriate cutting oil base oil. In this example, we choose mineral oil as the base oil, whose main characteristics are good lubrication and cooling properties.

Add emulsifier. Sodium petroleum sulfonate was selected as the emulsifier, which has good emulsification effect and lubrication performance.

Add antioxidants. Choosing phenolic compounds as antioxidants can extend the service life of the emulsion.

Add extreme pressure agent. Using sulfide as the extreme pressure agent can improve the extreme pressure lubrication performance of the emulsion and reduce tool wear.

Add rust inhibitor. The use of petroleum sulfonate as an anti-rust agent can prevent workpieces and tools from rusting and improve the reliability of the processing process.

Mix the above ingredients together, and after stirring, leaving and other steps, you can get the cutting oil emulsion.

From the above content, we can see that the process of preparing cutting oil emulsion involves many aspects, such as the selection of base oil, the addition of emulsifier, the addition of antioxidants and extreme pressure agents, etc. In practical applications, we need to choose the appropriate formulation scheme based on specific processing needs and process conditions to achieve the best cutting effect and workpiece quality.

In short, formulating cutting oil emulsion is a method that can effectively solve the problems existing in the cutting process and can greatly improve cutting efficiency and workpiece quality. In future mechanical processing, we should further promote and apply this method to improve our production efficiency and product quality.

Creating a cutting oil emulsion requires careful consideration of the specific application and desired performance. Here are some factors to consider when formulating a cutting oil emulsion:

1. Selection of base oil: Choose a suitable base oil that can provide the required lubricity and cooling performance. Common base oils include mineral oil, synthetic oil, and vegetable oil. Consider factors such as viscosity, thermal stability, oxidation resistance, and compatibility with the workpiece material.
2. Selection of emulsifier: Choose an emulsifier that can form a stable and uniform emulsion. Emulsifiers help disperse and stabilize oil droplets in water. Examples of commonly used emulsifiers include surfactants, fatty acids, and amines. The selection of emulsifier should consider factors such as compatibility with the base oil, emulsion stability and environmental factors.
3. Water quality: Consider the quality of the water used in the lotion. Hard water can negatively affect emulsion stability and performance, so water treatment or the use of softened water may be required.
4. Additives: Additives can enhance the performance of cutting oil emulsions. These may include corrosion inhibitors, biocides, extreme pressure (EP) additives and rust inhibitors. The choice of additives will depend on the specific application and desired performance characteristics.
5. Formula ratio: Determine the optimal ratio of base oil, emulsifier, water and additives to achieve the required emulsification performance. This may require experimentation and testing to find the best balance of properties such as lubricity, cooling, stability and tool life.
6. Mixing and stability: Determine appropriate mixing conditions and equipment to achieve a stable emulsion. Proper mixing is critical to ensure even distribution of oil droplets in the aqueous phase. Consider factors such as mixing speed, temperature and time to achieve the desired emulsion stability.
7. Testing and optimization: Conduct performance tests to evaluate the lubricity, cooling effect, corrosion resistance, tool life, etc. of the cutting oil emulsion. Adjust formulations as needed to optimize emulsion performance for specific applications.

It is worth noting that the formulation of cutting oil emulsions can be complex and depends on a variety of factors such as the machining process, workpiece material and desired performance characteristics. Consulting with experts in the field or conducting thorough research can help guide the development process.
