Which elements are related to the quality of large roll galvanized wire?

Galvanized iron wire manufacturers take you to understand the quality of large rolls of galvanized wire and what elements are related to the generation?
The quality of large roll galvanized wire is different. How can customers easily and accurately identify the quality of galvanized wire? It is related to the elements that make galvanized wire. Today, I will tell you some useful methods. According to the adhesion of the standard galvanized wire coating, the zinc layer of the plating parts should be firmly combined with the base metal, have enough adhesion, and do not fall off and protrude after the hammer test.
According to different industrial requirements, different provisions are selected to combine different alloy elements such as chromium, molybdenum and nickel in smelting. These pop-up materials are called alloy Kuang iron. The key components of galvanized wire directly from ore iron through the furnace are oxidation grades, silica and a few other things, and then carbon, silicon and other classics are added. This material is commonly known as cast iron.
Galvanized wire manufacturer galvanized wire, plating thickness of 3-4mm, zinc adhesion should be less than 460 g/m, that is, the average thickness of the zinc layer is not less than 65 g μm; When the coating thickness is more than 4 mm, the zinc adhesion should be no less than 610 g/m, that is, the average thickness of zinc layer is no less than 86μm. Standardized galvanized wire coating must be uniform, galvanized layer is basically uniform, with copper sulfate solution test corrosion five times without exposing iron.
Galvanized iron wire manufacturers should control the temperature at 30150℃ when electroplating. Because the chloride ions in the bath are very corrosive, so the glass heater is generally used in time. In continuous production, heating is not required, but cooling and cooling are required. Refrigeration method can not only thin - walled plastic pipe dense drainage into the groove side.
Cooling by running tap water, titanium tubes can also be used as temperature control devices. In the process of composite plating, in order to obtain the composite coating distributed in the matrix metal particles diffuse, it is necessary to mix plating solution. Mixing modes include mechanical mixing, gas mixing, ultrasonic mixing, bath circulation, etc.
