Problems solved by technology

[0002] In industrial production, due to the adhesion of rust to the metal, the reaction between the metal and oxygen will be accelerated, the corrosion of the metal will be accelerated, and the difficulty in removing the generated rust will be aggravated.
[0003] In the prior art, the way to remove the rust wrapped on the metal surface is often through the chemical reaction between industrial acid or industrial alkali and rust. , will cause extremely serious harm to the health of operators, and the high concentration of acid mist will bring safety hazards to production;
[0004] Because the new compound produced by the chemical reaction between industrial acid or industrial alkali and rust has no adhesion to the metal surface, the purpose of removing rust can be achieved, but the new compound produced in this process is very corrosive to the environment and human body Whether there is a certain impact, so it must be recycled, and recycling will increase the processing cost

Embodiment 1

[0018] A pure bio-environmental protection degradable metal rust stripper, comprising the following components: edible gelatin 12kg, onion extract 8kg, citrus extract 3kg, soybean oil 14kg, hair fat 20kg, potato extract 29kg; Just mix evenly. The pure bio-environmental protection and degradable metal rust stripper combines the chelating factor contained in it with the metal ions in the rust to form a chelate, thereby detaching from the metal surface. The chelating process is a physical Reaction, and will not produce other substances, so it can keep the metal surface clean. The chelate will undergo a reverse reaction after a period of time, releasing chelation factor and rust. Since rust is insoluble in water, it will precipitate, and it can be filtered Get rust, the pure bio-environmental protection and degradable metal rust stripper can be reused, thus saving cost and reducing environmental pollution.

Embodiment 2

[0020] A pure bio-environmental protection degradable metal rust stripper, comprising the following components of quality: edible gelatin 13kg, onion extract 10kg, citrus extract 5kg, soybean oil 17kg, hair fat 22kg, potato extract 33kg; each component Mix well and serve.

Embodiment 3

[0022] A pure bio-environmental protection degradable metal rust stripper, comprising the following components: edible gelatin 150kg, onion extract 130kg, citrus extract 60kg, soybean oil 190kg, hair fat 240kg, potato extract 340kg; Mix well and serve.

Abstract

The invention discloses a pure biological environment-friendly degradable metal rust remover, and belongs to the technical field of industrial rust removal. The dust remover comprises, by mass, 12-15parts of edible gelatin, 8-13 parts of onion extracts, 3-6 parts of citrus extracts, 14-19 parts of soybean oil, 20-24 parts of wool fat and 29-34 parts of potato extracts. The chelating factor has definite single directivity, and whether metal oxide or other substances are not in the grabbing range of the chelating factor except dust, that is, no corrosive damage is caused to reaction containersor to-be-treated metal. Because the chelating factor does not have any corrosive performance and the adhesion is weak, the cleanliness degree of the metal surface is higher than that of metal obtainedthrough traditional acid washing or alkali washing, and subsequent treatment of the metal is facilitated.

Description

technical field [0001] The invention belongs to the technical field of industrial derusting, and in particular relates to a pure biological environment-friendly degradable metal rust stripping agent. Background technique [0002] In industrial production, due to the adhesion of rust to the metal, the reaction between the metal and oxygen will be accelerated, the corrosion of the metal will be accelerated, and the difficulty in removing the generated rust will be aggravated. [0003] In the prior art, the way to remove the rust wrapped on the metal surface is often through the chemical reaction between industrial acid or industrial alkali and rust. , will cause extremely serious harm to the health of operators, and the high concentration of acid mist will bring safety hazards to production; [0004] Because the new compound produced by the chemical reaction between industrial acid or industrial alkali and rust has no adhesion to the metal surface, the purpose of removing rus...
