In the metal processing industry, machining fluids are essential auxiliary materials that perform multiple functions such as lubrication, cooling, rust prevention, and cleaning. However, in the process of metal processing, the processing fluid often produces a lot of foam, which will not only affect the stability and performance of the processing fluid, but also adversely affect the processing accuracy and product quality. Therefore, defoamers in the metal processing industry, as a key tool to solve this problem, are gradually receiving widespread attention and importance from the industry.

During the use of metalworking fluid, it is easy to produce a lot of foam due to mechanical agitation, air mixing, chemical reaction and other factors. These foam will occupy the effective space of the processing fluid, reduce its cooling and lubrication effects, and increase the pumping resistance and energy consumption of the processing fluid. In addition, foam may also carry impurities and microorganisms in the air, which will pollute the processing fluid and further affect the processing quality and equipment life.

Defoamer for metal processing industry is a chemical agent specially used to eliminate or inhibit foam in processing fluid. Defoamer can quickly penetrate into the surface of foam, reduce the surface tension of foam, destroy the stability of foam, and make foam burst and dissipate rapidly. The effective ingredients in the defoamer can be adsorbed on the liquid surface to form a film, which prevents air from entering the liquid interior, thus inhibiting the formation of new foam. Defoamer can not only eliminate foam, but also improve the fluidity, lubricity and cooling property of processing fluid, and improve processing efficiency and product quality.

There are various types of defoamers in the metal processing industry, which can be classified into surfactants, organosilicon, inorganic, and composite defoamers based on their main components and mechanisms of action. When selecting defoamers for the metal processing industry, it is necessary to comprehensively consider factors such as the specific type of processing fluid, processing technology, and processing requirements, and choose the appropriate type and amount of defoamer to be added.

With the continuous development of the metal processing industry, the requirements for machining fluid performance and machining quality are also increasing. As an important tool for improving processing efficiency and quality, defoamers in the metal processing industry have a very broad application prospect. In the future, with the continuous advancement of technology and the improvement of environmental awareness, green, non-toxic, harmless, and multifunctional defoamers will become mainstream products. At the same time, the defoamer industry will continue to innovate and upgrade to meet the demand for high quality, high efficiency, and low energy consumption in the metal processing industry.

In summary, defoamers in the metal processing industry play a crucial role in the metal processing process. By eliminating or inhibiting foam in the processing fluid, the stability and performance of the processing fluid are improved. Defoamers in the metal processing industry provide a strong guarantee for improving processing efficiency and quality. With the continuous development of the industry and the advancement of technology, the application prospects of defoamers in the metal processing industry will be even broader.
