2014 found that corrosion signs will also involve electrical corrosion

Current is generated during the production of corrosion signs, and the corrosion process is a primary battery working process. Make the local potential negative (Anode)Lose electrons and suffer corrosion. The electrochemical corrosion process consists of the following three links (As shown below) Chemical-related reactions that include at least one anode reaction and one cathode reaction. Stainless steel and other materials are the main raw materials of the brand factory, in the chemical industry. Corrosion occurs due to frequent contact with corrosive media and various acids, alkalis, salts, organic solvents and corrosive gases that strongly affect the service life of equipment. Corrosion not only causes huge losses to metal and alloy data. Moreover, it shortens the maintenance cycle of the equipment and increases the non-production time and repair cost; Corrosion makes the phenomena of running, running, dripping and leakage of equipment and pipelines more serious, causing a large amount of losses to raw materials and waste products, affecting the quality of products, polluting the environment and endangering human health; Equipment explosion, fire and other accidents caused by corrosion have caused equipment damage and stopped production, causing huge economic losses and even endangering human lives. So, it is extremely important to study the influence of corrosion on chemical equipment. Metal corrosion mainly includes chemical corrosion and electrochemical corrosion. Electrochemical corrosion is extremely dangerous to chemical equipment corrosion, so it is necessary to study electrochemical corrosion. Electrochemical corrosion of Cangnan Dake brand factory refers to the damage caused by electrochemical action of metal in contact with electrolyte solution. Intergranular corrosion and stress corrosion are the most important in electrochemical corrosion.
