Corrosion Phenomenon Of Disperser And Effective Anticorrosion Measures

2022-04-06

As one of the equipment used in chemical production, the disperser will come into contact with some materials to resist corrosion. There is no doubt that the corrosion of chemical equipment will not only damage the overall aesthetics of the equipment, but also seriously weaken the inherent safety application value of the equipment. Due to the limitation of various objective conditions, the anti-corrosion problem of chemical equipment cannot be well solved, which leads to major safety hazards in the operation and use of chemical equipment, and greatly reduces the safe service life of the disperser.

Usually, due to the particularity of the use environment of the equipment, in terms of the structure of the metal itself, it is easy to corrode, and the external environment such as temperature, humidity, and air will directly cause the metal to corrode. In an industrial environment, production involves drawing some redox gases, media, etc., and the production workshop has high humidity and high temperature, so a strong chemical reaction will occur on the metal surface, resulting in corrosion. The main reason for the corrosion of chemical equipment such as dispersers is that there are many harmful substances such as sulfur dioxide, hydrogen sulfide, carbon dioxide, halides, sulfides, and salt spray in the production medium of chemical enterprises during the production process.

In view of the problem of fast metal corrosion process in some chemical equipment, corrosion inhibitors can be considered. Corrosion inhibitors are low cost and simple to use. Essentially, corrosion inhibitors are substances that slow down the corrosion process of metals at low concentrations. After adding the corrosion inhibitor, a layer of adsorption film or passivation film will be formed on the surface of the electrode. This protective film can accelerate the polarization rate of the electrode while preventing corrosion caused by the flow of corrosion current to the device. Before choosing a corrosion inhibitor specifically, it is necessary to understand the type of metal, performance characteristics, and corrosive medium that the equipment is to be protected from.
