Embodiment 1

[0008] Embodiment 1, the present invention uses orthophosphoric acid as the main preparation raw material, and each formulation raw material is prepared by stirring and mixing according to the weight ratio, wherein 5-70 parts of deionized water, 20-30 parts of orthophosphoric acid, hydrogen oxidized 1-3 parts of zinc, 2-4 parts of manganese dihydrogen phosphate, 0.5-1.5 parts of sodium tripolyphosphate, 1-3 parts of sulfosalicylic acid, 1-3 parts of sodium oxalate, 2-4 parts of boric acid, molybdenum Sodium acid 0.5-1.5 parts, polyvinyl alcohol 0.5-1.5 parts.

[0009] When in use, the solvent prepared by the present invention can be directly painted or sprayed on the surface of the rusted steel parts, and the iron oxide formed on the surface of the steel parts due to rust can be dissolved by the solvent of the present invention and converted into a composite metal Salt protective film. Therefore, the present invention can directly carry out derusting treatment on the rusted p...

Embodiment 2

[0010] Embodiment 2, the present invention is formulated by the raw material of following weight parts, deionized water 50-70 parts, orthophosphoric acid 20-30 parts, zinc hydroxide 1-3 parts, manganese dihydrogen phosphate 2-4 parts, three 0.5-1.5 parts of sodium polyphosphate, 1-3 parts of sulfosalicylic acid, 1-3 parts of sodium nitrite, 2-4 parts of boric acid, 0.5-1.5 parts of sodium molybdate, 0.5-1.5 parts of polyvinyl alcohol; The preparation process is as follows: First, mix all the polyvinyl alcohol and deionized water in a weight ratio of 1:1-5, heat it to 40-60 degrees, stir repeatedly for 10-30 minutes, and then let it stand for 24 hours. Liquid A is the prepared polyvinyl alcohol polymer lubricating coating solution, which is non-toxic, tasteless, harmless to the human body, does not pollute the environment, and is cheap and easy to prepare. Then mix all the zinc hydroxide and deionized water according to the ratio of 1:0.5-10 by weight to prepare liquid B evenly...

Embodiment 3

[0011] Embodiment 3, the present invention is made up of the raw material drug preparation of following parts by weight, 60 parts of deionized water, 25 parts of orthophosphoric acid, 2 parts of zinc hydroxide, 3 parts of manganese dihydrogen phosphate, 1 part of sodium tripolyphosphate, sulfo water 2 parts of salicylic acid, 2 parts of sodium oxalate, 3 parts of boric acid, 1 part of sodium molybdate, and 1 part of polyvinyl alcohol. All the other are with embodiment 1 or 2.

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...
