Product Description

Corrosion inhibitor

Acid pickling commonly used acids are hydrochloric acid, sulfuric acid, phosphoric acid, hydrofluoric acid, sulfamic acid and other inorganic acids, and citric acid, EDTA and other organic acids. However, due to the corrosive effect of acid on metal equipment, especially inorganic acid corrosion is more serious, and the released hydrogen will spread to the metal interior, so that the washed equipment hydrogen embritterization. In addition, the precipitation of a large number of acidic gas, will worsen the working conditions. Therefore, corrosion inhibitors should be added during pickling to inhibit the corrosion of metals in acidic media, reduce the amount of acid used, improve the pickling effect, and extend the service life of thermal equipment. When pickling, not only the iron solubilization ability of acid should be considered, but also the scale composition, metal material, waste liquid treatment method and other factors should be considered. Therefore, choosing a good quality corrosion inhibitor is an important link of pickling, and understanding the corrosion inhibition performance of various corrosion inhibitors can be better for corrosion prevention work.
