| add to favorites | Protection Principle Of Galvanized Coil Hot-Dip Galvanized Layer | Cars |
| Why hot dip galvanized steel coil for sale is very popular, why steel sheets are subject to heat by zinc because zinc can form a film with good corrosion resistance on the surface in a corrosive environment. It not only protects the zinc layer itself but also protects the steel base. Therefore, the steel after the heat is passed through the zinc. Greatly extended service life. The service life is related to the coating and the environment in which it is exposed, as evidenced by atmospheric corrosion tests on hot-dip galvanized sheets. Hot-dip galvanized sheets have different corrosion rates in different ambient atmospheres. Theoretically, such corrosion may be carried out in two different ways, namely chemical corrosion and electrochemical corrosion. Chemical eclipse is a direct chemical interaction between the metal and the surrounding plate. For example, dry (absolutely moisture-free) gases and non-conductive liquid media (non-electrolytes), the chemical action on zinc is called typical chemical corrosion. Hot-dip galvanizing is currently showing a dynamic development. Hot tin plating is in the process of being replaced by electroplated tin. The same is hot-dip, so there are different prospects, determined entirely by their use and characteristics. Tinplate is mainly used indoors, such as cans, tea boxes, etc., so it does not require too thick plating. In addition, the tin plate is cathodic protection, and once the iron is dropped, the layer is completely lost in protection. Therefore, like a tin plate, it is often required to be uniform and non-porous and thin, and the characteristics of the electric arc are just to meet these requirements. Galvanized sheets are mainly used outdoors, and their corrosive environment is relatively harsh, so thicker slope layers are required. In addition, the zinc layer belongs to the anode protection, and the layer is not uniform. The problem is not big. The thicker the reservoir layer, the longer the service life, and the characteristics of the hot money zinc can meet these requirements. The electro-galvanized coating is uniform, and it is firmly combined with the right, and the surface of the well is less, but the thickness of the layer is thin. It is only one-fifth to one-seventh of the thickness of the hot-dip zinc layer. If the zinc plating of the electric slope is thickened, not only the power consumption is large, but also the residence time in the electrolyte needs to be increased so that the equipment should be increased accordingly. The layer thickness of the electric zinc is generally up to about 18 g/m, so the use range of the pillow is limited. Moreover, its production cost is high and its production is low. It is seen that the production capacity in the world is only about one-seventh of that of hot zinc. Although the production of electricity by zinc is constantly increasing, it is not a strong enemy of heat development by zinc. | ||
