In modern industrial production, as an important cooling lubricant, cutting fluid is widely used in the field of metal cutting. It can not only effectively reduce the friction between the tool and the workpiece, improve the processing efficiency, but also extend the service life of the tool and ensure the processing quality. Today, let's uncover the mystery of Hubei cutting fluid and understand its internal composition.
1. Base Oil Composition
The base oil of the cutting fluid is usually selected from mineral oil, synthetic oil or biosynthetic oil. These oils have good lubricating properties and can provide a stable base for cutting fluids. Mineral oil has a wide range of sources, low cost, but poor biodegradability; synthetic oil has better high temperature resistance and biodegradability, which is environmentally friendly; biosynthetic oil combines the advantages of the former two, which is environmentally friendly and efficient.
2. extreme pressure antiwear composition
In order to improve the lubricating performance of the cutting fluid, extreme pressure antiwear agents are usually added to it. Such additives can chemically react with the metal surface under high temperature and high pressure conditions to form a protective film, thereby reducing the friction between the tool and the workpiece and improving processing efficiency. Common extreme pressure antiwear agents include sulfur, phosphorus, nitrides, and the like.
3. anti-rust components
The rust inhibitor in the cutting fluid can effectively prevent the workpiece from rusting during processing. These rust inhibitors are usually polar compounds that can form an adsorption film with the metal surface to isolate moisture and oxygen, thereby preventing rust. Common rust inhibitors include zinc sulfate, phosphate esters, etc.
4. anti-emulsifying and stabilizing ingredients
In order to maintain the stability of the cutting fluid and prevent its deterioration and odor, it is usually necessary to add anti-emulsifiers and stabilizers. The anti-emulsifier can destroy the emulsion in the oil-water mixture and separate the oil and water, thereby keeping the cutting fluid clean; the stabilizer can improve the antioxidant properties of the cutting fluid and extend its service life.
5. environmental protection and safety
With the continuous improvement of environmental awareness, the selection of cutting fluid ingredients is also more and more attention to environmental protection and safety. Many cutting fluids use additives with low toxicity and low environmental impact to reduce the harm to the environment and human body. At the same time, when using cutting fluid, it is also necessary to pay attention to safety protection measures to avoid damage to the human body and the environment.
6. epilogue
As an important industrial oil, cutting fluid has a rich and diverse composition combination to meet various processing needs. Through in-depth understanding of the composition and function of cutting fluids, we can better select and use cutting fluids, improve processing efficiency and quality, and protect the environment.
