Product Details

Steel is easy to rust in air, water or soil, or even completely damaged. The annual loss of steel caused by corrosion accounts for about 1/10 of the entire steel production, hot-dip galvanizing is a method to prevent steel rust, from 170 years ago, hot-dip galvanizing should be used for the first time, has been widely used in the protection of steel, and in a variety of coating methods to protect the steel matrix, hot-dip zinc is a very good... It is in the liquid state of zinc, after a very complex physical and chemical action, not only on the steel plated with a thick pure zinc layer, but also to generate a zinc-iron alloy layer. This plating method not only has the characteristics of corrosion resistance of electrogalvanizing, but also has a zinc-iron alloy layer. It also has strong corrosion resistance that cannot be compared with electrogalvanizing. Therefore, this plating method is especially suitable for various strong acid, alkali mist and other strong corrosion environment.
Second, principle: hot dip galvanizing layer is formed by zinc in high temperature liquid state in three steps: 1, the surface of the iron base is dissolved by zinc liquid to form a zinc-iron alloy phase layer; 2, the zinc ions in the alloy layer further diffuse to the matrix to form a zinc-iron miscible layer; 3. The surface of the alloy layer is enveloped by the zinc layer.
Third, performance characteristics: (1) A thick dense pure zinc layer is covered on the surface of the steel, which can avoid the contact of the steel matrix with any corrosion solution and protect the steel matrix from corrosion. In the general atmosphere, the surface of the zinc layer forms a thin and dense zinc oxide layer surface, which is difficult to dissolve in water, so it plays a certain protective role on the steel matrix. If zinc oxide and other components in the atmosphere to form insoluble zinc salt, the corrosion protection is more ideal. (2) It has an iron-zinc alloy layer, which is compact and has unique corrosion resistance in Marine salt spray atmosphere and industrial atmosphere; (3) Due to the firm combination, zinc-iron miscible, with strong wear resistance; (4) Due to the good ductility of zinc, its alloy layer is firmly attached to the steel base, so the hot-plated parts can be cold-blanking, rolling, drawing, bending and other forms without damaging the coating; (5) After hot-dip galvanizing of steel structural parts, it is equivalent to a annealing treatment, which can effectively improve the mechanical properties of the steel matrix, eliminate the stress during the forming welding of steel parts, and is conducive to the turning of steel structural parts. (6) The surface of the hot-dip galvanized part is bright and beautiful. (7) Pure zinc layer is the most plastic galvanized layer in hot dip galvanizing, its properties are basically close to pure zinc, ductility, so it is flexible.
