                    The application of magnesium oxide in metalworking fluids is mainly reflected in its role as a pH regulator,anti-wear agent,and corrosion inhibitor,which can improve the performance of metalworking fluids and extend their service life.These applications utilize the chemical stability,high pH buffering capacity,and lubrication properties of magnesium oxide.The following will provide a detailed introduction to the specific application and functions of magnesium oxide in metalworking fluids:

PH regulator

                    Stable pH value:Magnesium oxide has a high pH value(usually between 9-10),which can serve as an effective pH regulator to keep metalworking fluids in a stable alkaline environment.A stable pH value helps prevent metalworking fluids from corroding metal workpieces and machine tools during the machining process due to the accumulation of acidic substances.

                    Neutralizing acidic substances:During metal processing,acidic substances such as fatty acids and hydrochloric acid can lower the pH value of the processing fluid,leading to corrosion problems.Magnesium oxide neutralizes these acidic substances,maintains the stability of the liquid,and reduces the corrosive effect on metal workpieces and equipment.

Anti-wear agent

                    Forming a protective film:The protective film formed by magnesium oxide on the metal surface can reduce direct contact between the tool and the workpiece,reduce mechanical wear,and extend the service life of the tool.This protective film also helps improve the machining accuracy and surface quality of the workpiece.

                    Reduce wear:In long-term continuous processing,magnesium oxide can reduce the wear of cutting tools and workpieces,maintain the sharpness of cutting tools and the dimensional accuracy of workpieces,thereby improving production efficiency and product quality.

Corrosion inhibitor

                    Corrosion prevention:Magnesium oxide can react with moisture on the metal surface to form a protective film that isolates oxygen and moisture from the air,effectively preventing corrosion of metal workpieces during processing and storage.This helps maintain the appearance and performance of the workpiece.

Long term protection:Even in humid environments,magnesium oxide can provide long-term rust protection,ensuring that metal workpieces are not affected by corrosion during transportation and storage.This is particularly important for metal products that require long-term storage or long-distance transportation.

Lubricant performance improver

                    Improve lubricity:Magnesium oxide fine particles are evenly dispersed in the metalworking fluid and can be filled into the micropores on the surface of the tool and workpiece,improving the lubrication performance of the machining fluid and reducing cutting resistance.This makes the cutting process smoother and improves the surface smoothness of the workpiece.

                    Improving surface quality:Due to the improved lubricity,the surface quality of the workpiece has been significantly improved,reducing the workload of later polishing and grinding,and lowering production costs.

Cooling performance enhancer

                    Improving thermal conductivity:Magnesium oxide has good thermal conductivity,which can improve the cooling efficiency of metalworking fluids,accelerate the heat dissipation of workpieces during the machining process,and prevent deformation and accuracy loss caused by overheating.

                    Stable working temperature:In high-speed and heavy-duty machining,magnesium oxide can help quickly stabilize the working temperature of the workpiece,maintaining consistency and stability in the machining process.

Antioxidant

                    Extended service life:Magnesium oxide can effectively inhibit the growth of bacteria and microorganisms in metalworking fluids,prevent their decomposition and deterioration,and thus extend the service life of metalworking fluids.This not only reduces material costs,but also reduces the frequency of waste liquid treatment and environmental impact.

                    Maintain liquid cleanliness:By inhibiting the growth of bacteria and microorganisms,magnesium oxide maintains the cleanliness of metalworking fluids and avoids processing quality issues caused by liquid contamination.

                    In summary,magnesium oxide has a wide and diverse range of applications in metalworking fluids,from stabilizing pH values,reducing mechanical wear,preventing rust,to improving lubrication and cooling performance,all of which significantly enhance the overall performance of metalworking fluids.In the future,with the continuous advancement of technology and the increasing demand for metal processing,the role of magnesium oxide in the field of metal processing fluids will become more important and widespread.
