Problems solved by technology

[0002] 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, the acid can react with the 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 pr

Abstract

The invention discloses a rust remover. The rust remover is characterized in that the rust remover comprises the following raw materials in parts by mass: 2-13 parts by mass of sodium silicate, 12-20 parts by mass of phosphoric acid, 1-10 parts by mass of lauryl sodium sulfate, 14-35 parts by mass of calcium hypophosphite, 2-15 parts by mass of potassium tetraborate and 200-400 parts by mass of water. The rust remover provided by the invention cannot cause harm to steel.

Description

technical field [0001] The invention belongs to the industrial field, in particular to a rust remover. Background technique [0002] 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...
