Environment-friendly rust remover

Abstract

The invention relates to the technical field of rust removers, in particular to an environment-friendly rust remover. The environment-friendly rust remover is characterized by comprising, by mass, 5-12 parts of glycerinum, 12-15 parts of trisodium phosphate, 15-19 parts of sodium dodecyl benzene sulfonate, 12-16 parts of lauryl sodium sulfate, 22-34 parts of hexamine, 5-9 parts of fatty glyceride, 3-8 parts of gluconic acid, 5-13 parts of potassium tetraborate, 10-20 parts of potassium hydroxide and 82-98 parts of deionized water. By the adoption of the formula, the environment-friendly rust remover can be used for rust removal and prevention under different processing technologies and different conditions. In addition, the environment-friendly rust remover has quite good rust removal and prevention performance, and is environmentally friendly, healthy, low in ingredient cost and low in energy consumption.

[0002] Ferrous metal (steel) is prone to rust when placed outdoors or in the open air, which not only affects the appearance quality, but also affects the normal progress of painting, bonding and other processes. Economic losses

Traditional chemical rust removal usually uses strong acid, which can chemically react with rust and metal oxides to generate soluble salts, so as to achieve the purpose of rust removal. At the same time of rust removal, acid can react with base metal to release hydrogen, hydrogen It can generate pressure on rust and insoluble scale, which is beneficial to their peeling and reduction of high-valent iron, and accelerates the pickling process, but the traditional acid treatment method also has obvious defects: that is, the large amount of hydrogen gas in the process The occurrence of hydrogen embrittlement will cause the steel to have hydrogen embrittlement, which will cause the mechanical properties of the metal to decline and affect the strength of the steel itself; at the same time, it is easy to form acid mist, which will affect the health of the operator and corrode the surrounding equipment and environment; the consumption of acid is also large. Increases disposal costs; these acids can over-corrode steel

In addition, the residues produced in large quantities need to be discharged frequently, which not only seriously corrodes industrial pipelines, but also pollutes the soil and the environment.
