What are the differences in the process of galvanized steel wire rope
Electrogalvanizing is to obtain a plating layer by electrodeposition through an external power supply. The obtained plating layer is composed of fine pure zinc grains. Cold galvanized (or electrogalvanized) is zinc plated by electroplating or other methods at room temperature. In theory, electroplated zinc can obtain a zinc layer of any thickness. At present, the amount of zinc on practical electroplating zinc can reach 1200g/m2. In general, the amount of zinc on the electroplated zinc layer can also reach 750g/m2.
Hot-dip galvanizing is to form a plating layer by physical thermal diffusion. First, an iron-zinc compound is formed, and a pure zinc layer is successively formed on the surface of the iron-zinc compound. The maximum value of zinc on hot-dip galvanizing is only 593g/m2. Hot-dip galvanizing will reduce the mechanical properties of the steel wire. Galvanized steel wire ropes with high strength and high corrosion resistance are required. Most of them are made of electrogalvanized steel wire. Hot dip galvanizing is zinc plating in a molten zinc bath at 450-480 degrees.
The essential difference between hot-dip galvanized steel wire rope and cold-dip galvanized steel wire rope is that, compared with cold-dip galvanized zinc layer, hot-dip galvanized steel wire layer has better corrosion resistance due to zinc-iron alloy layer. The surface of the hot-dip galvanized steel wire rope is hot-dipped with zinc-iron alloy, so his color should be a little darker. However, no chemical reaction occurs on the electroplated surface, so it is still the original color of zinc and looks brighter. In general, the zinc layer of hot-dip galvanizing is thicker and the corrosion resistance is better. The zinc layer of electroplated zinc is relatively thin, and its corrosion resistance is poor.
Hot dip galvanized steel wire is immersed in heated and ablated zinc liquid. The production speed is fast. The coating is thick but uneven. It consumes a lot of zinc metal. It forms an entry layer with the base metal. The corrosion resistance is good. Persevere for decades. Hot-dip galvanized steel wire has excellent resistance and elasticity, and the maximum amount of zinc can reach 300 g/m2. It has the characteristics of thick galvanized layer and strong corrosion resistance.
Nowadays, there are more and more types of steel wire. What kind of steel wire is the best? The galvanized steel wire we often use is very intact, because if it is other ordinary steel wire, we will not use it for a long time, it will easily occur corrosion, if we want it to have a continuous service life If the length of the side is long, then you have to brush the galvanized steel wire with a layer of other materials, so as to effectively prevent oxidation.
The use of galvanized steel wire is very wide, and in addition to its corrosion resistance, the appearance of galvanized steel wire is also very good. Compared with other black iron wires, galvanized steel wire seems to feel very high Yan value!
