How much do you know about the test method of cutting fluid anti foam performance?
February 19, 2023
Many enterprises have such worries. How to use so much foam when using cutting fluid? How to know whether the defoaming performance of cutting fluid is good?
Anti-foaming performance of cutting fluid is also an important aspect to measure the quality of cutting fluid, especially the cutting fluid used in CNC machining centers. Whether the anti-foaming performance is excellent or not directly affects the quality of metal processing, processing efficiency, and the subsequent maintenance and processing costs.
When the defoaming test of cutting fluid is carried out in the laboratory, especially for metal processing used in CNC machining centers and high-speed grinders, the defoaming performance of cutting fluid is required to be very high. Therefore, when preparing this type of cutting fluid, it is very necessary to test the defoaming performance of the cutting fluid. The defoaming performance of cutting fluid can be tested by using the spray gun to simulate the field. Many peer companies will release some experiments such as manual defoaming to prove to customers, but the manual defoaming experiment can not fully explain the problem, and is not reliable. The experiment shows that many manufacturers have suffered from using manual testing. In addition, performance test of defoamer: First, it depends on its compatibility, especially in aqueous systems; Second, it depends on whether there is anything precipitated after a period of inactivity, Finally, it is recommended to use filtration membrane in the field of chip cutting and laboratory simulation; At the same time, the data of cutting fluid maintenance and inspection also includes: cutting fluid concentration, PH value, anti-rust performance, anti-foam performance and anti-rust performance. The ph value of the cutting fluid can be detected by the ph value test paper. If the ph value of the cutting fluid is too high, it will affect the corrosion of metal and cause the skin allergy of operators. If the ph value is too low, it will affect the antibacterial and antirust properties of the cutting fluid. The concentration is also an important data for cutting fluid detection. At present, the refractometer is mainly used to detect the concentration of the cutting fluid. The use concentration of the cutting fluid affects the effect of metal processing, the service life of the tool and the normal use of the cutting fluid. The defoaming performance and antirust performance of the cutting fluid can not be ignored in the detection work. If the foam of the cutting fluid is abnormal and the antirust performance is reduced, please take corresponding measures to deal with it in time. Finally, I would like to remind you that in the defoaming performance test of cutting fluid, the national standard is not the only way to test the actual use effect! The defoaming performance of cutting fluid cannot be measured only at low temperature, but also at medium and high temperature. Because temperature changes have a great impact on the number of cutting fluid foam. After the above explanation, do you understand something? If you don't understand anything, please continue to pay attention to us.
