Discuss the causes of bacterial corrosion in metal processing oils and preventive measures

Thread Content

High bacterial levels in metal machining fluids can cause corrosion. Bacteria not only deplete the components of the processing fluid but also lower the pH value of the mixture. Bacterial metabolites include weak organic acids, which can lower the pH of the machining fluid and reduce its corrosion resistance ； If no detection is done, bacteria will cause the metal machining fluid to demulsify. For a single machine, metal cutting fluids contain a large number of bacteria. The simplest solution is to pour out the old fluid, thoroughly clean the entire system with an effective machine cleaning agent, rinse it with fresh water, and then add fresh metal cutting fluid at the recommended concentration. If it is difficult to obtain fresh solution, an appropriate fungicide can also be used. For central slot systems, preventive measures can be taken, including the proper use of bactericides to control bacterial growth.
