Steel rust remover is a kind of rust remover. Black metal (steel) is easy to rust when placed outdoors or in the open air, which will not only affect the appearance quality, but also affect the normal process of painting and bonding. If it is not handled in time, it will even lead to the scrapping of materials and unnecessary economic losses. The role of rust remover is to remove the oxide on the metal surface and expose the metal to the original surface.
Traditional chemical derusting usually uses strong acid, which can react with rust and metal oxides to generate soluble salts, thus achieving the purpose of derusting. When rust is removed, the acid can react with the base metal to release hydrogen, which exerts pressure on rust and insoluble scale, which is beneficial to their peeling and reduction of high-valent iron, and accelerates the pickling process. However, the traditional acid treatment method also has obvious defects:
That is, the generation of a large amount of hydrogen during treatment will cause hydrogen embrittlement of steel, decrease the mechanical properties of metal and affect the strength of steel itself; At the same time, it is easy to form acid mist, which affects the health of operators and corrodes surrounding equipment and environment; The amount of acid solution is also large, which increases the treatment cost; This acid will corrode steel. In addition, a large number of residues need to be discharged frequently, which not only seriously corrodes industrial pipelines, but also pollutes soil and environment. Its superior performance will bring you unexpected convenience.
It can be widely used in manufacturing, construction, repair, transportation, energy, electric power, petroleum and mining industries, and is suitable for rust removal of steel products such as mechanical equipment, vehicles, ships, ordnance, hardware tools, building templates and metal spare parts.
