What is the difference between galvanized steel cold base galvanized steel strip and hot galvanized steel strip?
In addition because of the high density of zinc, galvanized steel coating with the same aluminium zinc plate in the price there is no advantage, because the control relationship between zinc flower, zinc plating is more difficult to control, and anti oxidation performance and ALuminum zinc is poor compared to several times, so now mainly in the aluminum zinc as the main building materials and its the performance is 3-4 times of zinc, but the current electronics industry because of influence of hot dip galvanizing plate conductivity, appearance or using mainly low coating, building materials mainly to hot-dip aluminum zinc 100g/ square meters above. The main hot dipped aluminum zinc is 55%AL and 44.5%Zn.
The soaking process is mainly used in electroplating process, some appearance of repairing damaged more, a large number of plates or on the hot dip galvanizing process implementation. Cold is the use of zinc plating on the surface of the steel plate with filler replacement attached to a layer of zinc to the surface of the steel plate, the plating thickness is very small, generally between 10-50g/ square meters, anti-corrosion performance is poor, and its effect and general coating, sometimes as coated with a layer of anti rust oil in key parts this method should not be used so as not to affect the structure and properties of corrosion. The above is hot dip galvanized plate is heated to 500 DEG C into liquid zinc (zinc liquid temperature about 470 degrees Celsius), the formation of Zn Fe alloy coating and zinc layer, this method is the most commonly used, and the thickness of zinc can be controlled in more than 20 mu, ranging from 60g-275g/ square meters, even more thick, far better than cold plating process.
