Pure biological environment-friendly degradable metal rust remover

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...
