Release time:2024-11-29 Page-views:43

Metalworking fluid plays a crucial role in the metal processing, mainly used for cooling and lubrication, reducing friction, extending tool life, and improving machining accuracy. However, in the use of metalworking fluid, the generation of foam often becomes a headache. At this point, the role of defoamers becomes particularly important.

During the metal processing, due to friction and excessive flow rate, a large number of bubbles will be generated in the metal processing fluid. These bubbles will reduce the stability of the machining fluid, occupy effective volume, and lead to a decrease in cooling and lubrication effects, thereby affecting machining efficiency and quality. Foam can also increase gas-liquid contact, promote oxidation, and generate flotation effect, which may lead to uneven mixing of components, and may lead to product deterioration and corrosion. The addition of defoamers is precisely to solve these problems.

Defoamer can quickly eliminate bubbles and foam in metal processing, and play a lasting role in foam suppression. First, defoamer can cause bubbles and foam to break and disappear by reducing their surface tension. Under proper concentration, hydrophobic particles in defoamer can form a layer of surfactant film on the gas-liquid interface and the liquid interface, thus destroying the gas on the original gas-liquid interface and affecting the surface tension below, reducing the interfacial tension to a lower equilibrium value, so that bubbles and foam will break and dissipate instantaneously. This process effectively reduces the foam in the processing fluid and ensures the stability of the processing fluid.

Secondly, the use of defoamers can significantly improve the cooling and lubrication effects of machining fluids. The reduction of foam means that the processing fluid can more effectively contact and lubricate the metal surface, thus reducing friction and wear, and extending the service life of the tool. Meanwhile, a stable machining fluid can better absorb and disperse the heat generated during the cutting process, maintain temperature stability in the machining area, and improve machining accuracy and efficiency.

In addition, defoamers also help protect processing equipment and improve the cleanliness of the working environment. Foam will increase the viscosity of processing fluid, thus increasing the load of mechanical equipment, which may lead to equipment damage. Defoamer reduces the risk and protects processing equipment by reducing the generation of foam. At the same time, the reduction of foam also means that the cleaning work is reduced and the cleanliness and safety of the working environment are improved.

However, the effectiveness of defoamers is not constant and is influenced by various factors. For example, the amount of defoamer added, the composition of metalworking fluid, and the temperature and pressure of the working environment can all affect the defoaming effect. Therefore, in practical applications, adjustments need to be made according to specific situations to achieve the best results. At the same time, the addition of defoamers should be uniform and rapid, avoiding any agglomeration to ensure their uniform distribution and full effectiveness.

To sum up, metal processing fluid defoamer has significantly improved metal processing efficiency by rapidly eliminating bubbles and foam, stabilizing the properties of processing fluid, improving cooling and lubrication effects, protecting processing equipment and improving the cleanliness of the working environment. The correct selection and use of defoamers are crucial for metal processing techniques.
