How to deal with the corrosion of steel structure

Steel structure is a structure composed of steel material, is one of the types of structures, is mainly made of steel and steel plates, etc, they are connected by welding, bolts and rivets, now widely used in the large steel structure workshop, venues, super-tall field, due to the steel structure corrosion resistance is poor, especially in humid and corrosive medium environment, So the problem of steel structure corrosion occurs frequently, so let's analyze the causes of corrosion and protective measures.

[Corrosion causes]

According to our analysis, steel itself is easy to water, steam, chemical corrosive gases, acid and alkali salt solution under the action of electrochemical corrosion. Many impurities are distributed on the surface of steel, and these impurities become the cathode to the metal body because of their high point, while the metal becomes the anode. There are many tiny cathodes and anodes on the metal surface, which form many tiny galvanic cells. These tiny galvanic cells are called microcells, and the cells constantly react to produce corrosion products, which is the phenomenon of electrochemical corrosion. These reasons are a little abstract, but it is easy to understand that steel structure rust also belongs to a chemical reaction.

[Measures taken]

What are the anti-corrosion measures of speed steel supply chain company? If you want the steel structure to have a long life, and do not want to carry out large-scale maintenance, then long-term coating protection is a good choice. Good anti-corrosion coating not only has good product performance and anti-corrosion ability, but also can protect a wide variety of corrosive chemicals, including strong acids, strong bases, gases, solvents and oxidants. Of metal base material, composite materials and concrete has good adhesiveness and adhesion, good flexible stress, abrasion and impact resistance, resistance to hydraulic deoxidization, steam cleaning, also can online repair, low surface tension, has a good resistance to heat and cold cycle performance at the same time, choose the anticorrosive coating really can save a lot of maintenance effort, Later also can prevent steel structure corrosion more effectively.
