General phenolic bactericides are more toxic and cause pollution from waste fluids and have been used less frequently.

Product introduction:
Use of cutting fluid, management and protection of machine tool corrosion
Metal cutting fluids - emulsions are widely used because of their low cost. However, during its use, because users did not use the requirements of the standardization, they could not achieve the desired results during the use. For example, there are operators who are still using the emulsion when it fails to smell, resulting in rusting of the workpiece, corrosion of the machine tool, contamination of the environment, and the like. Therefore, the rational and effective use of emulsion is the focus of this article. 1 Emulsion preparation Water quality: The water used to prepare the emulsion is very important, and the suitable hardness of the water should be 50-200. Emulsions formulated with hard water often quickly delaminate, leaving large amounts of oil and soaps that are insoluble in water, affecting the results. On the other hand, if the water quality is too soft, the bubble may increase. Therefore, when preparing the emulsion, it is necessary to understand the situation of the water quality in advance. If the water quality is too hard, it must be pre-treated. Adding 0.1% to 0.3% of sodium tripolyphosphate or diethylamine tetraacetate to the water can reduce water quality. The role of hardness, the best use of deionized water. Dilution: The dilution of the cutting fluid is related to the stability of the emulsion. Before using the cutting fluid, it is necessary to determine the dilution ratio and the volume of the required emulsion. Then calculate the amount of emulsion used (raw solution) and the amount of water. The operation method is: selecting a clean container, pouring all the required water into the container, and then adding the emulsion liquid under low-speed stirring. When the emulsion is prepared, the speed of addition of the original solution is such that the non-emulsified stock solution does not appear. Pay special attention: The procedure for adding the emulsion stock solution and water cannot be reversed. Do not mix the emulsion directly in the oil pool (tank) of the machine tool. In actual operation, we often see that workers are very random when formulating emulsions. The operator sees that the cutting fluid in the water tank is less, then add water, add the concentrated liquid, and feel that the cutting fluid is not white enough after mixing, and then add the concentrate; It looks too strong and adds water. It is almost right to think what proportion is not proportional. The result is that the ratio of today's preparation is 1:20, tomorrow may be 1:30, which will definitely have a serious impact on the cutting fluid. In the actual use of water-soluble cutting fluids, different processing forms have different requirements for skidding and cooling. The general rule is that the greater the cutting load and the higher the lubrication requirement, the higher the preparation concentration of the cutting fluid; the higher the processing speed, the greater the requirement for cooling, and the lower the preparation concentration of the cutting fluid. In general, the change law of cutting load is: grinding <turning <milling <broaching. The processing speed is just the opposite. 2 Continuous use Because the cutting fluid is used in an open environment, and the general anti-bacterial properties of the components of the cutting fluid are limited, it creates conditions for the invasion and reproduction of bacteria and microorganisms. Since most of the bacteria growing in the cutting fluid are anaerobic bacteria, the long-term shutdown of the cutting fluid will lead to the formation of an oxygen-deficient environment conducive to the growth of bacteria, while the continuous use will enable the oxygen in the air to fully contact the cutting fluid. To some extent, the growth of bacteria is inhibited. Therefore, the use of cutting fluid is not afraid of static, so downtime should not exceed three days. There are two aspects of the maintenance and management of the emulsion emulsion clean emulsion: first, to prevent the mixing of external pollutants and timely removal, the other is to maintain the stability of the water-soluble working fluid: such as concentration, rust resistance, pH value, Antibacterial ability and so on. Although the general cutting fluid products have a certain degree of antibacterial ability, but some of the components are bacteria and microbial nutrients, so in the case of insufficient antibacterial capacity, the service life of the cutting fluid is limited. All kinds of debris are often the source of the corruption of the cutting fluid. For example: Cigarettes, tea, cotton yarn and other debris are randomly discarded in the water basin, contaminating the cutting fluid and becoming carriers and nutrients for the growth and reproduction of bacteria and microorganisms. Therefore, strict control must be exercised to prevent external foreign matter from mixing. Clean up immediately. In the case of almost no external foreign matter mixing, the materials that contaminated the cutting fluid are mainly metal powder and gravel fine powder, floating oil and free water, microorganisms and breeding materials, and the like. Floating oil refers to the oil used in the cutting fluid system of the machine tool transmission and hydraulic system oil leakage due to the lack of strict sealing of the machine tool. The hazard of floating oil is that some of the material of the cutting fluid system swells and distort, disturbing the emulsification balance of the emulsion, and destabilizing the emulsion. In addition, floating oil often floats on the surface of the emulsion oil, blocking the contact between the emulsion and the air, resulting in lack of oxygen in the emulsion, rapid propagation of anaerobic bacteria, and accelerated spoilage of the emulsion. 4 Intramuscular administration and countermeasures in the use of the cutting fluid When the emulsion turns from milky white to grayish brown and a foul odor occurs, a fungicide should be added immediately to kill the bacteria, or the emulsion should be replaced again. At present, the more commonly used low-toxic bactericide is Sandan oil, and the addition amount is about 0.1% to 0.2% (for the diluted emulsion), which has a significant effect on extending the life cycle of the emulsion.
