What are the reasons for the deterioration of corrosion inhibitors?
Thread Content
I would like to ask the experienced colleagues what causes corrosion inhibitors to deteriorate over time when used for an extended period
Many corrosion inhibitors gradually decompose in acidic environments to produce corresponding products. Many bacteria that can survive in acidic conditions, as well as oxygen present in the air, cause oxidation, leading to deterioration. Therefore, after being used for a certain period of time, it is necessary to replenish them in appropriate amounts to keep their concentration at the designed level.
It’s mainly the carbon dioxide and oxygen in the air that have an impact!
Attention should be paid to the storage location of the corrosion inhibitor; it should be kept away from air as much as possible
