What is the cause of the deterioration and smell of metal cutting fluid?
The main reasons for the deterioration and smell of metal cutting fluid are anaerobic bacteria and aerobic bacteria. Aerobic bacteria have a characteristic. They must have sufficient oxygen in the process of survival and reproduction. They will automatically disappear or cannot reproduce without oxygen. ; The silicone defoamer added in the metal cutting fluid is essentially insoluble in water, it just floats on the top of the liquid, it has a certain degree of blocking the entry of oxygen, and the use of this characteristic defoamer has a certain sterilization effect.
Anaerobic bacteria are just the opposite. They like to live and multiply in a space without oxygen. When the oxygen reaches a certain amount, they will be automatically extinguished by oxygen. The metal cutting fluid will emit a odor after stopping the circulation for a few days. It is the result of the rapid reproduction of anaerobic bacteria under high temperature in an anaerobic environment. If the time does not exceed the cut-off point, it should be properly treated for 10 minutes. Circulating oxygen at the proper mixing point of the metal cutting fluid can destroy this living space, and the anaerobic bacteria in the metal cutting fluid will not reach the limit of deterioration and smell.
