Metal rust remover

Abstract

The invention discloses a metal rust remover which is composed of, by mass, 5-7 parts of ammonium hydroxide, 15-25 parts of quartz sand, 8-10 parts of sodium iodide, 8-10 parts of coconut oil fatty acid, 6-8 parts of thiourea, 7-9 parts of hexadecyl benzene sulfonate, 1-3 parts of a corrosion inhibitor, 3-5 parts of dextrin, 20-30 parts of vinegar and 600-800 parts of deionized water. The metal rust remover does not contain inorganic acid, has no influences on health of the human body, does not corrode the environment, and is safe and reliable in performance and good in rust removal effect,

Description

technical field [0001] The invention relates to the technical field of rust removal, in particular to a metal rust remover. Background technique [0002] Metal 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. If it is not handled in time, it will cause scrapping of materials and unnecessary economic losses. The existing 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. Hydrogen, hydrogen can generate pressure on rust and insoluble scale, which is beneficial to the peeling off of the rust surface and the reduction of high-valent iron, and accelerates the pickling process, but the traditional acid treatment method also has obvious defects: the traditional Most of the acid used is inorganic acid, which will ca...

[0002] Metal 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. If it is not handled in time, it will cause scrapping of materials and unnecessary economic losses

The existing 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. Hydrogen, hydrogen can generate pressure on rust and insoluble scale, which is beneficial to the peeling off of the rust surface and the reduction of high-valent iron, and accelerates the pickling process, but the traditional acid treatment method also has obvious defects: the traditional Most of the acid used is inorganic acid, which will cause the mechanical properties of the metal to decline during use and affect the strength of the steel itself; at the same time, it is easy to form acid mist, which is corrosive and affects the health of operators and corrodes the surrounding equipment and environment. , there is a security risk
