Embodiment Construction
[0028] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0029] refer to figure 1 The steel structure anticorrosion process shown in the natural environment includes the following steps:
[0030] S100 derusting, using a high-pressure water gun to remove rust, scale and attached old paint on the surface of the steel structure;
[0031] S200 Apply anti-rust agent, and apply at least one layer of anti-rust agent on the surface of the steel structure;
[0032] S300 painting operation, spray primer, intermediate paint and top coat on the steel structure surface in sequence.
[0033] figure 2 It is a schematic flow chart of a preferred embodiment of the p...

The invention relates to the technical field of industrial maintenance methods, in particular to a steel structure corrosion prevention process in natural environment. The steel structure corrosion prevention process in natural environment comprises the following steps: S100, rust removal is conducted, specifically, rust, oxide skin and attached old paint on the surface of a steel structure are removed by using a high-pressure water gun; S200, an anti-rust agent is coated, specifically, the surface of the steel structure is coated with at least one layer of the anti-rust agent; and S300, painting operation is conducted, specifically, primer, intermediate paint and finish paint are sequentially sprayed to the surface of the steel structure. According to the steel structure corrosion prevention process in natural environment, the rust, oxide skin and attached old paint on the surface of the steel structure are removed through the high-pressure water gun firstly, and the surface of the steel structure is coated with at least one layer of anti-rust agent before painting operation, so that the problem that the paint is not tightly attached due to rust on the surface of the steel structure before painting operation is effectively solved; and the anti-corrosion effect and the anti-corrosion aging of the steel structure are improved, the safe service life of the steel structure is prolonged, and great contributions are made to the aspects of safe production, effective improvement of the production efficiency, reduction of the social and enterprise operating cost and the like of the country.
Description
technical field [0001] The invention relates to the technical field of industrial maintenance methods, in particular to a steel structure anticorrosion process in a natural environment. Background technique [0002] With the expansion of my country's steel structure construction market (high-rise buildings, bridges, main structures of the power industry, high-speed rail stations, etc.) Due to the characteristics of large-scale building steel structure itself, which is large in size, immovable, and the anti-corrosion position is often at a height of tens of meters or even hundreds of meters, the steel structure at a high position in the natural environment (especially in the coastal environment) How to carry out effective anti-corrosion has become an urgent and major issue to be solved. [0003] Moreover, most of the existing steel structure anti-corrosion processes have the problems of poor anti-corrosion effect and short anti-corrosion time limit, especially in coastal are...
