Emulsified cutting fluid is a common type of cutting fluid that consists mainly of emulsions of water and oil. It is usually made by mixing oil and water in a certain proportion and then emulsifying it by adding auxiliary agents such as emulsifiers and stabilizers. Emulsified cutting fluidsDefoamerIt is one of the important formulations of cutting fluid, which can solve the problem of foam generation well.
Cutting fluids can be divided into several types according to their composition and use, and the common ones include:
1.Emulsion cutting fluid: Composed of emulsions of water and oil, it has good cooling properties and lubricating properties, and is suitable for medium processing loads and general machining.
2.Fully synthetic cutting fluid: composed of synthetic base oil and additives, without mineral oil, with excellent cooling and lubrication effect, and at the same time environmentally friendly, suitable for high-speed, high-precision, difficult-to-machine material processing.
3.Aerosol cutting fluid: Aerosol is formed by atomizing and spraying cutting fluid, which is suitable for some special processing requirements.
In the cutting process, the vibration of the machine tool and the workpiece will cause the stirring and movement of the cutting fluid, resulting in fluctuations in the liquid level, resulting in bubbles and foam, so the cutting fluid needs to have a certain resistance to foaming.
Defoamer for emulsifying cutting fluidsIt is a kind of chemical substance that can effectively inhibit the production of a large number of bubbles on the surface of the liquid, which can effectively reduce the generation of foam, improve the heat transfer efficiency of the cutting fluid, and help improve the processing efficiency. Foam can also cause overflow during the working process, resulting in waste of cutting fluid and contamination of equipment and workpieces. At the same time, foam may also affect the circulation and filtration of the cutting fluid, which increases the cleaning and maintenance of the cutting fluid. The addition of defoamers can help reduce these problems and extend the life of the cutting fluid.
