Problems solved by technology

[0004] However, in the process of anti-corrosion construction of the steel structure used indoors, when the surface of the steel structure is not thoroughly treated, the surface of the steel structure is coated, which is likely to affect the bonding force and strength of the coating and the surface of the steel structure. Corrosion resistance, especially affects the bonding force and corrosion resistance of the base film of the coating and the surface of the steel structure, which can easily cause the steel structure to continue to corrode even under the protection of the coating, causing the anti-corrosion layer to peel off and affecting the steel structure. Anti-corrosion properties

Embodiment 1

[0061] A steel structure anticorrosion construction process, comprising the following steps:

[0062] S1. Surface cleaning of steel structure: Clean up the scale, welding spatter, oil and dust on the parts to be painted.

[0063] S2. Sandblasting and derusting: place the steel structure on the stirrup, fill the sand tank with quartz sand, keep the pressure of the air compressor at 0.5Mpa, keep the spray angle at 40°, and place the nozzle at a distance of 120mm from the surface of the steel structure. Quartz sand is evenly sprayed onto the surface of the steel structure until the surface of the steel structure reveals a metallic luster, and then the rust dust and residual abrasives are removed with a brush.

[0064] S3. Surface roughness treatment of the steel structure: Use a grinding wheel to grind the surface of the steel structure to make the steel structure have a certain surface roughness, and then use cotton yarn to clean the residual abrasive on the surface of the steel...

Embodiment 2

[0075] A steel structure anticorrosion construction process, the difference from Embodiment 1 is that it includes the following steps:

[0076] S1. Surface cleaning of steel structure: Clean up the scale, welding spatter, oil and dust on the parts to be painted.

[0077] S2. Sandblasting and derusting: place the steel structure on the stirrup, fill the sand tank with quartz sand, keep the pressure of the air compressor at 0.5Mpa, keep the spray angle at 50°, and place the nozzle at a distance of 130mm from the surface of the steel structure. Quartz sand is evenly sprayed onto the surface of the steel structure until the surface of the steel structure reveals a metallic luster, and then the rust dust and residual abrasives are removed with a brush.

[0078] S3. Surface roughness treatment of the steel structure: Use a grinding wheel to grind the surface of the steel structure to make the steel structure have a certain surface roughness, and then use cotton yarn to clean the res...

Embodiment 3

[0089] A steel structure anticorrosion construction process, the difference from Embodiment 1 is that it includes the following steps:

[0090] S1. Surface cleaning of steel structure: Clean up the scale, welding spatter, oil and dust on the parts to be painted.

[0091] S2. Sand blasting and derusting: place the steel structure on the stirrup, fill the sand tank with quartz sand, keep the pressure of the air compressor at 0.6Mpa, keep the spray angle at 70°, and the distance between the nozzle and the surface of the steel structure is 150mm. Spray evenly onto the surface of the steel structure until the surface of the steel structure reveals a metallic luster, and then use a brush to remove rust and residual abrasives.

[0092] S3. Surface roughness treatment of the steel structure: Use a grinding wheel to grind the surface of the steel structure to make the steel structure have a certain surface roughness, and then use cotton yarn to clean the residual abrasive on the surfac...

Abstract

The invention relates to the field of steel structure corrosion resistance, in particular to a steel structure anti-corrosive construction technology. The steel structure anti-corrosive construction technology includes the following steps that S1, the surface of a steel structure is cleaned, so that impurities on the surface of the steel structure are removed; S2, derusting by sandblast is conducted; S3, roughness treatment is carried out on the surface of the steel structure; S4, primer preparation is performed; S5, steel structure primer is coated, so that a bottom film is formed on the surface of the steel structure; S6, finish paint of the steel structure is coated; and S7, steel structure products are inspected and accepted. The steel structure anti-corrosive construction technology has the beneficial effects that the impurities on the surface of the steel structure can be removed completely before coating, the binding force of coatings and the surface of the steel structure can be better increased, corrosion resistance of the coatings and the surface of the steel structure can be better improved, and the corrosion resistance of the steel structure is good.

Description

technical field [0001] The invention relates to the technical field of steel structure anticorrosion, more specifically, it relates to a steel structure anticorrosion construction technology. Background technique [0002] Steel structure engineering is a structure mainly made of steel, which is one of the main types of modern building structures. The annual steel production in the world exceeds 100 million tons, and the scrapped steel equipment due to corrosion is equivalent to about 30% of the annual production. How to improve the rust removal and anticorrosion construction technology of steel structures has become an urgent problem to be solved. Before taking various anti-corrosion measures for steel structures, rust removal is a necessary process step. [0003] For steel structures used indoors, after derusting the steel structures, anti-corrosion construction should be carried out in order to avoid re-corrosion of the surface. Anti-corrosion construction is mainly to ac...
