    In the copper wire drawing process, copper wire drawing oil plays a vital role. It can reduce friction, reduce wear, and ensure the smooth progress of copper wire in the wire drawing process. However, in the actual production process, copper wire drawing oil often produces foam, which not only affects production efficiency, but also may lead to a decline in product quality. Therefore, the application of defoamer for copper wire drawing oil is particularly important.
    The main working principles of defoamer for copper wire drawing oil are as follows:

    1. Reduce surface tension: Defoamer can reduce the surface tension of copper wire drawing oil, making the liquid film of bubbles thinner, thereby causing bubbles to rupture.

    2. Destroy the stability of bubbles: Defoamer can destroy the surface film structure of bubbles, causing bubbles to lose stability and then rupture.

    3. Control the generation of bubbles: Some defoamers can adsorb on the surface of copper wire drawing oil before bubbles are formed, preventing air from entering the oil, thereby controlling the generation of bubbles.

    In the production and use of copper wire drawing oil, there are mainly the following methods for applying defoamers:

    1. Direct addition method: Add the defoamer directly to the copper wire drawing oil and stir evenly.

    2. Add after dilution: For some high-concentration defoamers, they can be diluted before adding to the copper wire drawing oil.

    In short, defoamers for copper wire drawing oil play an important role in the copper wire drawing process. By reasonably selecting and using defoamers, the foam problem of copper wire drawing oil can be effectively controlled, production efficiency and product quality can be improved, and the sustainable development of copper wire drawing technology can be promoted.
