Problems solved by technology

Many anti-corrosion methods used in the past, such as: coating anti-corrosion coatings, metal spraying, cement coating, bottom zinc-rich primer, surface epoxy coating, protective cover, etc., but due to the limited followability of the coating material itself , cannot keep up with the expansion, bending, and deformation of steel parts caused by external forces and cracks occur, which affects the anti-corrosion effect and life; for corroded uneven steel surfaces, especially protruding edges, valves, flanges, storage tanks Edge plates, spherical joints, screws, nuts, and various complex-shaped mechanical equipment cannot be well matched, so that moisture, air and other corrosive media penetrate, shortening the anti-corrosion life; and must be coated before coating Thoroughly clean the surface of protected objects, especially various uneven steel surfaces, corrosion holes, gaps and complex-shaped mechanical equipment, which are difficult to clean and waste anti-corrosion materials. High, limited anti-corrosion effect, short life

Embodiment 1

[0024] This embodiment is a detailed description of the present invention based on the example of the construction of the oxidative polymerization type anticorrosion technology in the valve of the protected object:

[0025] 1) Remove burrs, rust, and surface dust, water and oil from the valve of the protected object.

[0026] 2) Apply anti-corrosion paste evenly on the surface of the treated object to be protected,

[0027] 3) After coating, fill the irregularly shaped part of the object to be protected with filling material to make the surface smooth.

[0028] 4) Wrap the anti-corrosion tape on the valve of the object to be protected after the above three steps. When winding, stretch the anti-corrosion tape to overlap 50% of the winding to ensure that each part is 2 layers. Smooth the surface of the anti-corrosion tape by hand so that it fits tightly on the surface of the steel structure.

[0029] 5) Use a brush or roller to evenly apply the surface adhesive on the surface ...

Embodiment 2

[0036] This embodiment is a detailed description of the present invention based on the example of oxidation polymerization anti-corrosion technology in the oil and gas pipeline construction of the protected object:

[0037] 1) Remove burrs and rust from the pipeline of the protected object, and remove surface dust, water and oil.

[0038] 2) Apply anti-corrosion paste evenly on the surface of the treated object to be protected,

[0039] 3) After coating, fill the irregularly shaped part of the object to be protected with filling material to make the surface smooth.

[0040] 4) Wrap the anti-corrosion tape on the oil and gas pipelines to be protected after the above three steps. When winding, stretch the anti-corrosion tape to overlap 50% of the winding to ensure that each part has 2 layers. Smooth the surface of the anti-corrosion tape by hand so that it fits tightly on the surface of the steel structure.

Abstract

The invention relates to a corrosion prevention technology, and in particular relates to an oxidation polymerization type corrosion prevention method which is suitable for iron and steel structures of electric power plants, stay cables of bridges, various storage tank edge plates, oil-gas pipelines, valves, flanges, H-section steel, spherical joints, screws, screw caps and mechanical equipment with various complex structures. According to the method, a corrosion prevention cream, a filling material and a corrosion prevention belt are arranged on the surface of a protected steel body in sequence, and then an adhesive is brushed on the outer surface layer of the corrosion prevention belt; the corrosion prevention cream can be used for filling corrosion hole parts, and can be used for construction with rust and original coatings, namely the surface of a protected object which is coated can be simply treated, so that the labor cost is saved, and the construction efficiency is high. The filling material is used at shaped parts of flanges, valves, storage tanks, spherical joints, screws, screw caps and the like, and is convenient in molding. The chemical compounds soaked on the corrosion prevention belt have good adhesive force, can obstruct the contact between metals and corrosive media including water, air and the like, and has good corrosion prevention performance; the corrosion prevention belt has good flexibility and structural displacement tracing ability and can be closely matched with the protected article.

Description

technical field [0001] The present invention relates to anti-corrosion technology, specifically a kind of anti-corrosion technology suitable for steel structures of power plants, bridge stay cables, edge plates of various storage tanks, oil and gas pipelines, valves, flanges, I-beams, spherical joints, screws, nuts and various An oxidative polymerization type anti-corrosion method for complex-shaped mechanical equipment. Background technique [0002] Steel structures of power plants, stay cables of bridges, edge plates of various storage tanks, oil and gas pipelines, valves, flanges, I-beams, spherical joints, screws, nuts, and mechanical equipment of various complex shapes, etc., exposed to outdoor steel structures , Continuously exposed to wind, sun and rain, the corrosion is very serious. In order to ensure its safe operation and save resources, it is necessary to formulate targeted anti-corrosion countermeasures. In particular, coastal power plants are affected by the ...
