Corrosion Inhibition of Sodium Tungstate Inhibitor On Carbon Steel
In recent years, in order to save fresh water resources and reduce the cost, some of the coastal chemical, metallurgy, electric power and petrochemical enterprises began to use seawater as a type of industrial circulating cooling water. Although this practice has many advantages, in the sea cl - content is high, easy to produce metal corrosion, metal corrosion is one of the most important destructive factors, which can cause corrosion and perforation of equipment and pipes, cause serious corrosion, and cause enormous economic losses and social harm. In order to reduce the probability of metal corrosion, it is a simple and effective anti-corrosion method to add inhibitors to circulating cooling water. Only common chromate, nitrite, phosphate and other corrosive agents are toxic preparations, excessive use is tantamount to quenching thirst with poison, research and development of low toxicity, non-toxic and effective corrosion inhibitors have a greater significance. ...
