Citric acid has a strong chelating effect, it can complex Fe3+ and weaken the promotion of corrosion by Fe3+. It can remove metal oxide scales such as iron and copper, is easy and safe to use and is suitable for a wide range of materials. Since the molecule does not contain c1-, it does not cause stress corrosion of equipment. As a cleaning agent, citric acid has a lower corrosion rate on steel than hydrochloric acid. Citric acid is mainly used to remove rust, but is less soluble in calcium, magnesium and silica scale, so it is mainly used to clean new large installations. Citric acid can not remove calcium and magnesium scale and silicate scale, but citric acid and sulfamic acid, hydroxyacetic acid or formic acid mixed use, can be used to clean iron rust and calcium and magnesium scale citric acid and EDTA mixed use, can be used to clean heat exchangers. The corrosion inhibitor added to the citric acid cleaning solution is mainly thiourea at a dosage of 0. 1%, or 0.06% thiourea can be used mixed with other corrosion inhibitors. In addition, it can also be used in medicine, the sodium salt of citric acid can prevent blood clotting, the calcium salt can be used as an antacid for the stomach, and the barium salt is toxic.
