What is the proper PH value of cutting fluid, emulsion and emulsified oil?
December 23, 2021
Generally speaking, the pH value of the cutting fluid, emulsion and emulsified oil that we use normally is alkaline, between 8.0-9.5; when the pH of the cutting fluid is greater than 9, the cutting fluid, emulsion, and emulsified oil are irritating to human skin It can cause skin allergies and corrosion of non-ferrous metals among workers; when the pH of cutting fluid, emulsion, and emulsified oil is less than 8, the cutting fluid, emulsion, and emulsified oil are susceptible to bacterial infestation, and bacteria are easy to multiply, leading to cutting fluid. Emulsion and emulsified oil are degraded and smelly, which will reduce the service life of cutting fluid, cutting fluid, emulsion and emulsified oil.
Emulsified oil (cutting oil): Medium-load emulsified oil with the latest lubrication technology, environmentally friendly formula, does not contain sulfur, chlorine additives, does not irritate the skin, is non-corrosive to copper and aluminum, and has a short-term anti-rust function for processed steel materials. It can effectively prevent metal contact and sintering, meet the cutting process of turning, milling, drilling, boring, reaming, tapping, and engraving, and significantly improve the processing accuracy and surface finish of the processed workpiece. Cutting fluid (emulsion): The latest product specially developed for alloy processing. It has a stable microemulsion particle structure, contains boundary extreme pressure lubricants, provides good lubrication performance, effectively reduces the friction in the cutting area, and prevents the tool and the processed metal from occurring The case of soldering! The cutting fluid uses water-soluble and oil-soluble rust inhibitors to protect equipment and workpieces from rust; excellent biochemical stability, strong anti-corruption ability; PH value is about 9.2, no skin irritation, no allergies. The PH value of cutting fluid, emulsion and emulsified oil should be adjusted according to the processed materials. The applicable PH value of different materials is different. For example, if the PH value of processed aluminum is too low, the problem of oxidation will occur. So we can use the PH tester to adjust the PH value of the cutting fluid.
