As we all know, the application of steel structure is more and more extensive, in offices, industrial plants, buildings, warehouses, sports facilities, stadiums and other fields can often see it. Steel structure is easy to corrosion, general need to rust, galvanized or paint, and to regular maintenance, then it corrosion when how to protect and protect it? Let's talk about it together!
There are many ways to maintain the corrosion of steel structure, one is to change the internal structure of the metal, such as making a variety of corrosion-resistant alloys, adding chromium, nickel and other common steel made of stainless steel. Second, the protective layer method, in the metal surface covered with a protective layer, so that the metal products and the surrounding corrosion media isolated, so as to prevent corrosion. For example, steel parts on the surface of oil, vaseline, paint or covered with enamel, plastic and other corrosion-resistant non-metallic materials. Thirdly, by means of electroplating, hot-plating and spraying, a layer of metal which is not easy to be corroded, such as zinc, tin, chromium and nickel, is plated on the surface of steel. These metals often form a dense oxide film because of oxidation, to Stop the corrosion of steel by water and air. Fourth, electrochemical protection method, using the principle of galvanic cell to protect metal, try to eliminate galvanic corrosion caused by GALVANIC cell reaction. Electrochemical protection is divided into anodic protection and CATHODIC protection. CATHODIC protection is the most widely used protection method. Fifth, the corrosion medium is treated to eliminate the corrosion medium, such as often clean metal equipment, in the precision instrument placed desiccant and in the corrosion medium to add a small amount of corrosion inhibitor can slow down the corrosion rate.
Above is the steel structure corrosion protection and protection methods to share, I hope to help you. If you are interested in our products, we warmly welcome people from all walks of life to contact us and look forward to creating a better future with you.
