There are a few key factors to consider when choosing a cutting fluid defoamer:
Cutting fluid type: You need to determine whether to use an oil-based or water-based cutting fluid defoamer according to the specific conditions and requirements of the machining process. Oil-based defoamers are suitable for low-speed processing and provide long-term foam suppression.
Performance of defoamersChoosing a defoamer with good defoaming performance can effectively control the generation of foam and prevent foam from affecting the cooling effect of cutting fluid.
Composition of the defoamerCutting fluid defoamer is usually made of special modified silicon, polyether and other raw materials through special process, which has good solubility and high temperature resistance, acid and alkali resistance.
Process scenes: Different types of defoamers may be required for different process scenarios. For example, emulsified oil defoamers blend well with oil-based cutting fluids and are suitable for increasing the brightness of industrial parts and increasing the life of work machines.
Diffusion and permeability of defoamers: Choose a defoamer with excellent diffusion and permeability, which can quickly diffuse and penetrate into the bubble film, causing the film wall to thin and bursting the bubble.
Stability of the defoamer: Considering the stable foam that can be generated by the cutting fluid, it is necessary to select a defoamer that can effectively destabilize the foam.
Circulatory system: If the cutting fluid uses a recirculating system, the defoamer chosen should be able to maintain a stable defoaming effect during the cycle.
In summary, when choosing a cutting fluid defoamer, you should decide on the most appropriate type of defoamer based on the specific processing process, equipment requirements, and the nature of the cutting fluid. It is advisable to consult with a professional defoamer** before purchasing, or to test small batches to ensure that the selected defoamer meets your specific needs.
