Environment-friendly derusting conditioning fluid for metal equipment of flue-curing barn

Abstract

The invention relates to environment-friendly derusting conditioning fluid for metal equipment of a flue-curing barn. By the environment-friendly derusting conditioning fluid, the technical problem of poor derusting effect or high cost and the like in the conventional deruster is solved. According to the key point of the technical scheme, the environment-friendly derusting conditioning fluid is prepared by mixing and stirring the following raw materials in part by weight: 50 to 70 parts of deionized water, 20 to 30 parts of orthophosphoric acid, 1 to 3 parts of zinc hydroxide, 2 to 4 parts of manganous dihydrogen phosphate, 0.5 to 1.5 parts of sodium tripolyphosphate, 1 to 3 parts of sulfosalicylic acid, 1 to 3 parts of sodium nitrite, 2 to 4 parts of boric acid, 0.5 to 1.5 parts of sodium molybdate and 0.5 to 1.5 parts of polyvinyl alcohol. By the environment-friendly derusting conditioning fluid, rust melting and rust proofing are completed at one time, so that the labor production efficiency is improved greatly, and the cost of conditioning rust is reduced. The environment-friendly derusting conditioning fluid can be widely applied to a surface treatment process for steel devices.

Description

technical field [0001] The invention relates to a rust-removing and anti-rust solvent for iron and steel products, in particular to an environmentally friendly rust-removing treatment liquid for metal equipment in a barn. Background technique [0002] At present, the scope of use of steel products has involved various industries that people need, but the oxidation and corrosion of steel have also caused great problems for the use of steel products. The amount of loss caused by rust every year in the world is astonishing, and some existing rust removal technologies have certain unsatisfactory points, such as troublesome construction and incomplete treatment, and mechanical and manual rust removal are easy to cause wear and tear of items and are not easy to complete Cleaning, using the method of chemical rust removal, the discharged metal compounds are easy to pollute the water quality, and generally have poor anti-rust performance. Therefore, it is necessary to research and d...

[0002] At present, the scope of use of steel products has involved various industries that people need, but the oxidation and corrosion of steel also cause great problems for the use of steel products.

The amount of loss caused by rust every year in the world is astonishing, and some existing rust removal technologies have certain unsatisfactory points, such as troublesome construction and incomplete treatment, and mechanical and manual rust removal are easy to cause wear and tear of items and are not easy to complete Cleaning, using chemical derusting method, the metal compounds discharged by it are easy to pollute the water quality, and generally have poor anti-rust performance. Therefore, it is necessary to research and develop newer technologies and products to improve and improve rust removal and anti-rust technology
