How to improve the quality of galvanized iron wire
The disadvantage of hot-dip wire hot-dip galvanizing in galvanized iron wire equipment is that the mechanical properties of the wire are poor, that is, the strength is reduced and the toughness is sharply reduced. Therefore, the quality of the manufactured galvanized iron wire is inferior to that of the light iron wire. How to improve the quality of galvanized iron wire?
When the galvanized iron wire is drawn by using a zinc wire which has been previously plated with zinc, there is no mechanical deterioration. The toughness of this wire is 15 to 25 percent higher than that of galvanizing, and in some cases even slightly exceeds the toughness of the wire.
The strength of the iron wire which is firstly plated and pulled out is also higher than that of the first wire after plating. The wire which is plated with zinc and then drawn is not only tough but also has high strength. The strength limit of the drawn galvanized iron wire is relatively low, which is due to the reason of zinc, because the strength of zinc technology is several times smaller than the wire itself.
Hot-dip galvanizing of the drawn wire is difficult, and it is less likely that a finer and finer wire will be plated with a smooth zinc layer of the desired thickness. The finest wire is broken and small, and the surface is relatively large, so the degree of erosion is the greatest, but the plating quality is particularly thin. If the zinc is first plated and then pulled, the Baidu of the zinc layer on the finished wire can be adjusted.
For the finest wire, the thickness of the zinc layer obtained by first plating and then drawing is more than 100% larger than that of the first plating. This will improve the quality of galvanized iron wire equipment.
