In the process of metal processing, metalworking fluid plays an important role in cooling, lubrication, and chip removal. However, due to mixing, circulation, spraying and other operations, a large amount of foam is often produced in metalworking fluid. These foam will not only affect the fluidity and spraying effect of the processing fluid, but also reduce the processing efficiency, and even cause equipment damage. Therefore, the use of defoamers in metalworking fluids is particularly important.

The existence of foam will hinder the flow of metal working fluid, which will lead to the cutting fluid can not reach the cutting area smoothly, thus affecting the processing effect. Defoamer can quickly eliminate these foam, restore good fluidity of the processing fluid, ensure that the cutting fluid can evenly cover the metal surface, and improve processing efficiency. Foam also affects the lubrication effect of cutting fluid, leading to the increase of cutting force and cutting temperature, thus affecting the cutting accuracy. The use of defoamer can eliminate foam, improve the lubricating performance of cutting fluid, reduce the cutting force and cutting temperature, thus improving the cutting accuracy and processing quality. Too much foam will lead to equipment blockage, nozzle blockage and other problems, and even equipment damage in serious cases. The use of defoamer can effectively reduce the production of foam, reduce the failure rate of equipment, extend the service life of equipment, and thus improve the processing efficiency. Foam will accelerate the oxidation and deterioration of metalworking fluid and shorten its service life. The addition of defoamer can significantly reduce the production of foam, extend the service life of processing fluid, reduce the replacement frequency and cost, and thus improve the overall processing efficiency.

In order to ensure the optimal performance of defoamers in metal processing, it is necessary to select and use defoamers reasonably. Firstly, the type and dosage of defoamer should be determined based on the specific composition and usage conditions of the machining fluid. Different types of metalworking fluids have different requirements for defoamers, and it is necessary to choose defoamers that are compatible with them. Secondly, during the processing, an appropriate amount of defoamer should be added as needed and thoroughly stirred to ensure that the defoamer can be evenly dispersed throughout the entire processing fluid.

Taking aluminum alloy cutting as an example, aluminum alloy cutting fluid is easy to produce foam during use, which affects cutting efficiency and processing quality. The use of defoamer for aluminum alloy cutting fluid can quickly eliminate foam, improve the fluidity and lubricity of the cutting fluid, and thus improve the cutting efficiency and machining accuracy. The use of defoamers in the processing of aluminum alloy components such as engine cylinder blocks and wheel hubs can ensure the normal cooling, lubrication, and chip removal effects of cutting fluid, improving production efficiency and product quality.

Defoamers for metalworking fluids play a crucial role in the metalworking process. Through reasonable selection and use of defoamer, the foam in metalworking fluid can be effectively eliminated, the fluidity and lubrication of the fluid can be improved, and the processing efficiency and product quality can be improved. For any enterprise engaged in metal processing, the use of metal processing fluid defoamers is essential. With the continuous development of metal processing technology, the performance and application of defoamers will also continue to improve, making greater contributions to the development of the metal processing industry.
