Domestic rust remover

Abstract

The invention discloses a domestic rust remover. The domestic rust remover is prepared from the following materials including, by weight, 100-200 parts of citric acid, 50-100 parts of acetic acid, 100-200 parts of gluconic acid, 20-30 parts of tea seed powder, 20-45 parts of borax, 20-35 parts of wool fat, 10-30 parts of cellulose, 15-20 parts of sapindus mukorossi gaertn, 5-10 parts of rice, 15-25 parts of table salt, 400-800 parts of deionized water and 100-200 parts of coconut oil. In the domestic rust remover, the rice is rich in starch and amino acid, and the starch, the amino acid and tea saponin in the tea seed powder can be combined with iron on the surface of an appliance to form a layer of compact protecting film, so that the iron appliance is prevented from being rusted again.

Description

technical field [0001] The invention relates to the field of household chemicals, in particular to a household 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 wil...

[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 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.

However, in family life, household appliances are often rusted due to metal plating being rubbed off or other reasons, especially kitchen utensils are often exposed to water and oxygen-rich environments, and frequent use causes friction, which promotes its rusting

In general, manual rubbing is used to remove rust, which is relatively labor-intensive and time-consuming, and the household rust removers currently on the market are generally used in industry, and most of them contain harmful ingredients, which are not suitable for rust removal of household appliances; patent application number The patent document for 201410235983.7 discloses a household rust remover, the invention only removes rust, wherein glycerin and edible oil are used to form a moisturizing protective film on the surface of the utensil after rust removal, and this protective film is easy to clean fall off, and the utensils will rust quickly
