Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of anti-corrosion, in particular to a composite anti-corrosion steel structure. Background Art
[0002] Steel structure is a structure made of steel materials and is one of the main types of building structures. Due to the advantages of good plasticity and toughness, high strength, good seismic resistance, short construction period and easy production, steel structure is widely used in high-rise structures, large-span structures, industrial plants and other fields.
[0003] For example, in the steel structure project of a chemical plant, due to the high humidity all year round, the acid and alkali mist in the workshop easily forms a slight acid or alkaline dew, which accumulates on the surface of the steel structure, causing electrochemical corrosion, resulting in a greatly increased corrosion rate. The corrosive gases and ions in the air, such as SO2, H2S, CL - It is easy for them to penetrate the cross-linked network of the outer anti-corrosion layer and directly cause penetration corrosion to the pipe wall substrate, leading to swelling, rusting and cracking and peeling of the outer anti-corrosion layer.
[0004] Therefore, the current conventional anti-corrosion processes in chemical plants, such as zinc-rich primer + micaceous iron intermediate paint + polyurethane topcoat, are more effective against chemical corrosion under dry conditions, but are difficult to resist electrochemical corrosion, gas and ion penetration corrosion under humid conditions. In the long run, they are likely to cause corrosion and thinning of steel structures, causing hidden dangers to operational safety.
