In the field of metalworking, the generation of foam is often a headache. These foams can not only interfere with the processing process, affect product quality, and may even damage equipment. In order to solve this problem, semi-synthetic defoamers for metal processing were born.

Metalworking semi-synthetic defoamers are chemical additives specifically designed to control and eliminate foam in metalworking fluids. Compared to fully synthetic defoamers, semi-synthetic defoamers combine the advantages of organic and inorganic components to achieve higher efficacy and a wider range of applications.
1. Reduce surface tension: The surfactant components in the defoamer can reduce the surface tension of the metalworking fluid, making the foam more likely to burst. The reduction in surface tension makes the foam walls more fragile and therefore more susceptible to rupture by external factors.
2. Damage the foam film: Some components in the defoamer can penetrate into the foam film and destroy the stability of the film, resulting in the rupture of the foam. This process typically involves the interaction between the defoamer and the surfactant in the foam film.
3. Inhibit foam formation: In addition to eliminating existing foam, semi-synthetic defoamers can also inhibit the formation of new foam. This is achieved by reducing the concentration of surfactants in metalworking fluids or changing their properties.
Semi-synthetic defoamers for metal processing are widely used, involving casting, cutting, grinding, cleaning and other metal processing links. Proper use of defoamers can not only improve processing efficiency and reduce equipment maintenance costs, but also ensure product quality and improve production efficiency.
However, it is important to note that while semi-synthetic defoamers play an important role in metalworking, their use also needs to be adapted on a case-by-case basis. Excessive use of defoamers can have a negative impact on the performance of metalworking fluids, so adequate testing and adjustment is required in real-world applications.
In general, semi-synthetic defoamers for metalworking can effectively control and eliminate foam problems in the metalworking process by reducing surface tension, destroying foam film and inhibiting foam formation, which provides strong support for the efficient and stable production of metalworking industry.
