What are the types of lithium bromide solution corrosion inhibitors? What are the addition methods? Let me introduce them you below.

 
I. Types of Lithium Bromide Solution Corrosion Inhibitors: To inhibit the corrosion of solution on metallic iron, besides isolating air as much as possible, adding a certain amount of corrosion inhibitors into the solution is also an effective measure to prevent corrosion. This is because corrosion inhibitors can form a dense protective film on the metal surface, thereby preventing direct contact between the solution and the steel plate, achieving the purpose of anti-corrosion.

 
Currently, the most commonly used corrosion inhibitors in absorption units are lithium chromate and lithium molybdate. Lithium chromate is a yellow liquid and has a harmful effect on the environment, so fewer manufacturers are using it. Lithium molybdate is a colorless liquid that is harmless to the environment and has been adopted by technologically advanced manufacturers.

 
II. Addition Methods of Lithium Bromide Solution Corrosion Inhibitors: An excessive or insufficient amount of corrosion inhibitors in the solution will affect the formation of the protective film. Additionally, as the unit operates, the corrosion inhibitors will gradually be consumed. Therefore, regular and timely addition of corrosion inhibitors is an important maintenance measure to ensure the normal operation of the unit.

 
The above is an introduction to the types and addition methods of lithium bromide solution corrosion inhibitors. I hope everyone can gain an understanding.
