I believe that friends in the metal processing industry are no strangers to cutting fluids. It is widely used in the field of metal processing. However, after a long period of use, manufacturers have also discovered many shortcomings of cutting fluids, the most serious of which is the foaming problem. In order not to be affected by foam, manufacturers have added a cutting fluid defoamer. What role can it play?

First of all, let's understand the reasons for the foaming of the cutting fluid
The foaming of the cutting fluid is mainly because the liquid level of the machining fluid is too low, and the flow rate of the cutting fluid is too fast, so that the bubbles that appear have no time to overflow and accumulate more and more. When the cutting fluid is used, the fluid circulation pump is not tightly sealed, and the air will enter the circulation system to dissolve with the cutting fluid, and it is difficult for these gases to escape, resulting in the generation of foam. In addition, the processing equipment is not cleaned properly, there are solvent residues and impurities in the cutting fluid, these reasons will also cause the generation of foam.
Some people may think that it is not just some bubbles, as for all the fuss. In fact, the impact of these bubbles is very large.
·Excessive foam will make the lubricating performance, cooling performance and anti-rust performance of the cutting fluid ineffective, resulting in quality problems of the product
·The foam will also accumulate in the oil tank, which not only wastes the volume of the oil tank, but also reduces the utilization rate of the oil tank
·In the process of processing, the foaming of cutting fluid will also block the line of sight, which is not conducive to the observation of processing conditions, and ultimately affects the quality and accuracy of processing.
·And a large amount of foam will remain on the surface of the metal processing equipment, which will cause certain corrosion to the processing machine tools and props, and shorten the service life of the processing equipment.
The cutting fluid defoamer is a defoamer made of modified polysiloxane as the main component, together with an emulsifier, a dispersant, and a stabilizer. It can be used in metal processing, cutting fluid, metal cutting fluid, etching fluid, electrolyte wire cutting fluid, alkali extraction process defoaming, dehydrating agent and other processes to defoaming and suppressing foaming.
It is added to the foam system by destroying the elasticity of the film and causing the bubble to burst and the defoamer will diffuse to the gas-liquid interface, making it difficult for the surfactant with the function of foam stabilization to restore the elasticity of the film to defoaming and suppressing the foam. Strong adaptability, continuous defoaming and anti-foaming under high temperature, high shear, high acid-base environment, and good water solubility, can quickly penetrate into the foam, disperse quickly, and is well compatible with cutting fluids. No oil drift, no precipitation.
