The use of preservatives in the spraying of steel structures can not only extend the service life of steel, but also effectively reduce the tilt and deformation of steel. This not only ensures the safety and stability of the building structure, but also improves the economic benefits and construction efficiency of the project.
First of all, preservative spraying can significantly enhance the corrosion resistance of steel. Steel is prone to corrosion when exposed to moisture, salt and other corrosive environments. This corrosion not only weakens the strength of the steel, but may also cause its surface to be uneven, which can trigger stress concentration and structural deformation. By spraying preservatives on the surface of the steel structure, a protective film can be formed to isolate the contact between the steel and external corrosion factors, slow down the corrosion rate, and ensure that the steel maintains stable physical properties throughout the service life.
Secondly, preservative spraying helps to reduce the tilt and deformation of the steel. In the environment of temperature change and humidity change, steel will be deformed to a certain extent due to thermal expansion and cold contraction and wet expansion and dry contraction. This kind of deformation will lead to structural deviation and instability under long-term action, affecting the safety of buildings. Preservative spraying can not only reduce the corrosion rate of steel, but also reduce the microscopic defects and inhomogeneity of its surface, thereby reducing the deformation caused by environmental changes. In addition, some preservatives have good high temperature resistance, which can form a stable protective layer on the surface of the steel, further reducing the structural deformation caused by temperature changes.
