According to the galvanized iron wire manufacturer, galvanized iron wire is the selection of excellent low carbon steel, through drawing molding, pickling rust removal, high temperature annealing, hot galvanized, cooling and other processes. The following points should be paid attention to in the use of galvanized iron wire:
Cold galvanized is in the plating tank through the current unidirectional zinc gradually plated on the metal surface, production speed is slow, uniform coating, thin thickness, usually only 3-15 microns, bright appearance, poor corrosion resistance, generally a few months will rust. Compared with electrogalvanizing, hot galvanizing has lower production cost and less impact on the environment than electroplating.
Thus, when zinc is sufficient in a solid melt, the two atoms of zinc and iron disperse with each other. The zinc atoms in the iron matrix are moved into the lattice of the matrix, and the iron elements are gradually formed into alloys. The zinc composition of iron and intermetallic compound FeZn13 in molten zinc solution and the bottom of hot galvanized sheet can be used as zinc slag. The pure zinc layer composed of zinc leaching solution is hexagonal crystal.
Using activated carbon mat to remove surface active substances, or through filtration to make the foam is not too stable, this is an effective measure; Other measures should also be taken to reduce the amount of surfactant introduced to Z.
Hot-dip galvanized wire is widely used in chemical equipment, petroleum processing, Marine exploration, metal structure, electric power transmission, shipbuilding and other industries. It has been widely used in recent years in agricultural fields such as agricultural medicine sprinkler irrigation, greenhouse and construction industry such as water and gas transmission, wire casing, scaffolding, Bridges, highway guardrail and so on.
Galvanized wire mesh is divided into hot dip galvanized wire mesh and cold galvanized wire mesh. Galvanized steel wire net selects the high quality low carbon steel wire, iron wire factory made by precision of automation machinery welding technology processing, smooth surface, firm structure, integrity is strong, even if the local cutting of galvanized steel wire net, or local also under pressure from loose phenomenon, after molding, wire mesh galvanized corrosion resistance good, has the advantage that the general steel mesh does not have.
The corrosion or discoloration of galvanized iron wire in the atmosphere caused by oxygen, moisture and other pollution impurities is called rust or rust. After galvanized iron wire rusting, it will affect the appearance quality, seriously affect the use, and even cause scrap, so galvanized iron wire must be properly kept and pay attention to rust prevention.
Cold galvanized, generally speaking, do not need heating, galvanized amount is little, this galvanized parts are easy to fall off in wet environment. Hot dip galvanizing, also known as hot dip galvanizing, is to melt the zinc ingot at high temperature, put some auxiliary materials in, and then dip the metal structural parts into the galvanized groove, so that the metal members are attached to a layer of zinc layer. The advantage of hot dip galvanized is that its anticorrosion ability is strong, the adhesion and hardness of galvanized layer is better.
