After the cable tray is galvanized, there is a thick pure zinc layer on the steel surface, which can prevent the steel substrate from contacting with the corrosion solution and protect the bridge steel substrate from corrosion. In ordinary atmosphere, a very thin and dense zinc oxide layer is formed on the surface of the zinc layer of Shandong cable bridge. This zinc oxide layer is not easily soluble in water, so it can protect the steel substrate. After forming insoluble zinc salt with other components in the atmosphere, its anti-corrosion effect is more ideal.
First, the steel surface is covered with a thick and dense pure zinc layer, which can prevent the steel substrate from contacting with any corrosive solution and protect the steel substrate from corrosion.
Second, when exposed to the air, a thin and dense zinc oxide layer is formed on the surface of the zinc layer, which is not easily soluble in water, so it plays a certain role in protecting the steel substrate.
Third, if the zinc oxide and other components in the atmosphere form insoluble zinc salts, the anti-corrosion effect is more ideal. When the product has an iron-zinc alloy layer, it is closely bonded and has special corrosion resistance in the marine salt fog environment and industrial environment.
The cable tray has strong wear resistance due to its strong binding force and the mutual dissolution of zinc and iron. Because zinc has good ductility and its alloy layer is firmly adhered to the steel substrate, it can form hot-plated parts through cold stamping, rolling, wire drawing and bending without damaging the coating.
Hot dip galvanizing of steel structural parts is equivalent to one annealing treatment, which can effectively improve the mechanical properties of the steel substrate, eliminate the stress during the forming and welding of steel parts, and facilitate the turning of steel structural parts. The surface of the parts after hot galvanizing is bright and beautiful.
Pure zinc coating is a plastic zinc coating in hot galvanizing. Its performance is basically close to that of pure zinc, and it has ductility, so it has flexibility. What else do you not understand? Welcome to our website http://www.sddlqj.cn Consulting!
