The purpose of boiler water treatment is to remove impurities that are harmful to the boiler, prevent boiler scaling and corrosion, ensure good steam quality, ensure the safe and economic operation of the boiler while achieving the purpose of energy-saving and energy conservation.
This paper briefly introduces the factors influencing the corrosion rate of metals in the pickling process and uses them as a basis for selecting the appropriate corrosion inhibitor.
Organic polymers have a long history of application as corrosion inhibitors, such as natural gums, starches, and other early acidic corrosion inhibitors.
In recent years, the research of environment-friendly water-based rust inhibitors has received wide attention at home and abroad, especially the development of long-lasting water-based rust inhibitors has become a trend.
The commonly used cleaning agents can be roughly divided into acidic, alkaline, and neutral systems. Acidic and alkaline cleaning agents are used more frequently in the market. Due to the presence of acid and alkaline substances in the system, the cleaning effect of cleaning agents tends to be more significant. Improved, but at the same time, acid-base substances can also cause metal corrosion, which adds incredible difficulty to the formulation design of the cleaning agent.
To inhibit metal corrosion, scientific researchers have been tirelessly exploring the work through the continuous research before and after, roughly summed up three effective anti-corrosion technology: the surface coating treatment and the material alloying treatment the third is electrochemical protection.
