Molecular formula :
nature : to improve the pickling process and reduce the pickling time, enhance the quality of pickling, prevent corrosion and hydrogen embrittlement over, and reduce the formation of acid mist, the acid lotion into pickling various additives such as corrosion inhibitors, wetting agent , Defoamer, thickening agents, such as acid inhibitors. Defoamer and thickening agent used in jet pickling. Pickling commonly used inhibitors have Urotropine (6-methyl-4 amine), xylene thiourea (if small), imidazole compounds, imidazoline compounds pyrazolone derivatives such. Lotion acid used by the wetting agent, most non-ionic and anionic surfactants, such as fatty alcohol polyoxyethylene (peregal), alkylphenol polyoxyethylene (OP), polyoxyethylene (20) sorbitan ester oil alone (Tween 80), Airborne washing etc. General amount to 10 ~ 12g / L, respectively. Surfactant is a wetting, and infiltration by emulsifying, dispersing, solubilization and Decontamination role in improving the pickling process can shorten the pickling time. Mist inhibitors generally surfactants derived compound, such as the development of China's production of "841" net wash acid fog agent, and inorganic acid used in conjunction with, not only with fog obviously, but also has pickling derusting increase, in addition to scaling, degreasing effect, also metallic materials there was a certain inhibition.
