For the classification of corrosion, there are generally two classification methods. First, classification is based on the mechanism of corrosion generation, and second, classification is based on the causes and appearance of corrosion.
According to the mechanism of corrosion, it can be divided into electrochemical corrosion and chemical corrosion. Electrochemical corrosion mainly refers to the metal material in contact with the electrolyte solution, due to the occurrence of surface electrode reaction and corrosion, this reaction is generally redox reaction, the main factor is the environmental humidity and temperature problems; Chemical corrosion means that a strong chemical reaction occurs between the metal surface and the medium in contact with the metal surface, so that the metal is subjected to certain damage. The reason for this corrosion induction is mainly high temperature and dry environment. According to the appearance and classification of corrosion, the classification can be divided into stripping layer corrosion, industrial atmospheric corrosion, high temperature oxidation corrosion, and atmospheric corrosion of the sea.
In those environments where industrial pollution is severe, there are many volatile substances such as sulfides, carbon dioxide, and hydroxides in the air, as well as some industrial dust. These are all media that can easily cause corrosion. These media in a humid environment, acid gas will combine with water to form inorganic acids, these acids have a strong corrosion performance, so it will induce corrosion. In an industrial atmosphere environment, equipment is caused by a combination of electrochemical corrosion and direct chemical corrosion. The nature of all corrosion is actually an oxidation process in which metal elements form ions after losing electrons. The main difference between electrochemical corrosion and industrial atmospheric corrosion is the difference in the environment in which they occur.
The solution:
Corrosion of equipment is closely related to the material of the equipment. In the selection process of chemical materials, it is necessary to focus on the occurrence of corrosion and pay attention to the rationality of material selection. The nature of the medium, the temperature of the environment, and the pressure of the operation must be fully taken into account. The requirements of raw materials design the structure and type of equipment.
The design of the structure should focus on the production requirements and stress characteristics of the production and operation of chemical equipment. In the design, we need to pay attention to several aspects:
The first is that the structural requirements of the product's products should be consistent with the requirements for corrosion resistance of the production chemical products;
The second is to pay attention to the stability and fluency of the operation of the chemical equipment, to prevent the suspension of the corrosive medium, the uneven distribution of the heat load, and the condensation of steam and the accumulation of corrosion products. Finally, it is necessary to pay attention to the protection of external forces to prevent Fatigue corrosion due to alternating stress.
