Metal tube inner wall cleaning solution and preparation method thereof

Abstract

The invention relates to a metal tube inner wall cleaning solution and a preparation method thereof. The metal tube inner wall cleaning solution is mainly prepared from the following components: 4-6 parts of chloroprene rubber, 8-14 parts of acrylic acid, 30-40 parts of tea leaves, 50-60 parts of animal livers, 40-60 parts of corn starch, 60-70 parts of an antirust oil agent, 90-110 parts of ethyl alcohol, 4-6 parts of a phenolic aldehyde-butyronitrile rubber copolymer, 4-6 parts of deionized water, 9-11 parts of passivation solution, 19-21 parts of a mixture of modified amine and polyamide, 5-15 parts of urea, 6-10 parts of ammonium hydroxide and 90-120 parts of a cleaning agent. The metal tube inner wall cleaning solution is easy to prepare, low in cost, harm-free, water-saving, gentle to hands, safe and simple in cleaning process and good in cleaning effect and has no corrosive effect and small influence on human hygiene and health, and as a natural rust remover, the cleaning solution can be wiped, or washed with water, is simple to prepare, safe and non-toxic and has a good rust removal function on metal.

Description

Technical field: [0001] The invention relates to the field of metal pipe manufacturing, in particular to a metal pipe inner wall rust remover and a preparation method thereof. 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, a 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 ...

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, a 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.
