Instructions for galvanizing hot-galvanizing steel wire rope
The difference between galvanized steel wire rope and electric galvanized steel wire rope
Hot galvanizing wire rope and cold galvanizing wire rope have this essential difference in process.
Electrogalvanizing is to obtain the coating by the external power source and electrodeposition, and the coating obtained is composed of fine pure zinc grains.
Electrogalvanizing (or cold galvanizing) is zinc plating or other plating at room temperature.
In theory, any thickness of zinc can be obtained by electroplating. The available zinc on electric galvanization can reach 120g/m2 at present. Generally, the amount of zinc on electric galvanizing layer can be up to 750g/m2.
Hot galvanizing is formed by physical thermal diffusion. First, the iron-zinc compound is formed, and then the pure zinc layer is formed on the surface of the iron-zinc compound
The maximum amount of zinc on hot galvanizing was only 593g/m2. Galvanizing will reduce the mechanical property of the steel wire, require high strength and high corrosion-resistance galvanizing steel wire rope, use electricity galvanizing steel wire twist more. Hot galvanizing is zinc plating in molten zinc at 450-480 degrees.
Hot galvanizing wire rope and cold galvanizing wire rope essential difference is: hot galvanizing zinc layer and cold galvanizing compare, because have zinc iron alloy layer, anticorrosion performance is better. Hot-dip galvanized steel wire ropes are coated with zinc and iron alloy, so their color should be slightly darker. And electroplate surface did not produce chemical reaction so still zinc is ecru, look more bright.
Generally speaking, the zinc layer of hot galvanizing is thicker, and the corrosion resistance is better. Zinc electroplating is thinner and has poor corrosion resistance. (unless the cold galvanizing zinc layer also reaches the degree of thick zinc layer) the difference between the use and price of hot galvanizing steel wire rope and cold galvanizing steel wire rope is the following questions that our users are concerned about
