Steel structure is one of the commonly used building structures. In addition to industrial plants, it is also widely used in multi-high-rise civil building structures, large theaters, bridge structures and office building structures. In actual engineering, steel is often corroded due to lack of maintenance, which affects the quality of engineering structure and leads to accidents such as building collapse. The following has sorted out the relevant points of steel structure anticorrosion, let's take a look with steel structure house manufacturers. 1. Hot-dip galvanizing anti-corrosion method Hot-dip galvanizing anti-corrosion technology is currently advanced and widely used technology, and it is also a steel anti-corrosion method with good use effect and economic benefits. structure. In the actual project, the workpiece to be plated is mainly immersed in the molten metal zinc tank, and then plated, so that a pure galvanized layer is formed on the surface of the steel, and a zinc alloy coating is formed on the subsurface, so as to play the role of anti-corrosion of the steel. . Generally speaking, the hot-dip zinc coating is dense and thin, generally about 30~50μm. During construction, it should be ensured that the surface of the hot-dip galvanized parts used is smooth, free from peeling, no leakage, no drip, roughness and zinc thorns, and no residual solvent residue. At the same time, it is also necessary to try not to design components with matching surfaces, so as to avoid the incomplete pickling in the gap of the bonding surface or the poor cleaning of the acid solution, which will cause the phenomenon of yellow water flow on the galvanized surface. 2. Painting and anti-corrosion method The construction cost of the painting and anti-corrosion method is low, but the outdoor maintenance cost is high, and the anti-corrosion effect is not good, so it is more used for indoor steel structures or outdoor steel structures that are relatively easy to maintain. In actual engineering, pure zinc powder is first dissolved in solvent, additives and film-forming substances to form a zinc-rich primer, and then it is painted on the anti-corrosion workpiece, and it is cured on the surface of the workpiece through film formation, thereby isolating corrosion. Dip people in medium. When using mechanical tools for painting and anti-corrosion, it is necessary to explore the ingredients according to the weather, temperature and humidity of the construction site and the surrounding media, adjust the viscosity, and flexibly control the speed of the spraying machine to avoid spraying blanks caused by the speed of the spraying machine, or the paint surface caused by too slow. Accumulation, sag, and affect the later drying time. At the same time, 4 to 5 times of paint should be applied during construction, and the next paint should be sprayed after the paint has dried to 80% or completely dried. 3. Arc spraying anti-corrosion method The arc spraying method has high bonding force, strong adaptability to the size of components, almost unlimited shape and size of components, and has a long life of corrosion resistance and wear resistance, which can reach more than 10 months. The anti-corrosion coating does not require any other maintenance during the month's service life, so this method is often used in underwater or underground structures. During construction, sandblasting and rust removal should be carried out on the surface of the steel member to expose the metallic luster and roughen, and then the metal should be melted by burning an arc between two continuously fed metal wires, and sprayed on the surface of the steel member. Arc spray zinc and aluminum coatings are formed on the metal components that have been sandblasted and derusted in advance, thereby forming a long-term anti-corrosion composite coating. In addition, vertical cross spraying should be carried out in an environment where the relative humidity is less than 85% (the spray gun and the workpiece are in a vertical direction). If vertical spraying cannot be carried out, the slope of the spray gun and the surface of the workpiece should not be less than 45°.
