Electric galvanized wire is dipped in the zinc solution of heating ablation, the production speed is fast, the coating is thick but not uniform, the market allows a low thickness of 45 microns, up to 300 microns or more. The color is dark, the zinc metal is consumed, and the matrix metal is formed into the entry layer, the corrosion resistance is good, and the outdoor environment of hot dip galvanized can adhere to decades.
The wire used for barbed wire is woven or welded with low carbon steel wire, medium carbon steel wire, high carbon steel wire, stainless steel wire and other materials. The production process includes: general braid, embossed braid and spot welding. If the material is steel wire, after equipment processing into a network, it is called wire mesh.
1. Principle. Because zinc does not change easily in dry air, and in humid air, the surface can form a very dense film of zinc carbonate, which can effectively protect the interior from corrosion. And when the coating is damaged for some reason and the matrix is not too large, the zinc and steel matrix form a micro cell, so that the fastener matrix becomes the cathode and is protected. It is widely used in automobile transportation and other industries, but what is needed is the trivalent chromium passivation layer, zinc nickel alloy plating closed coating, reduce the harmful and toxic layer of hexavalent chromium passivation.
Stainless steel wire is characterized by good corrosion, in chemical plants or pharmaceutical industry can often be used to stainless steel wire, suitable for acid, alkali environment. Aluminum alloy wire is characterized by high temperature, can adhere to the high temperature of more than 100 degrees Celsius does not fade, and has good corrosion, patience is also very good. It can be used for device manufacturing in construction industry.
With the development of mining industry, the classification of pig iron is already very broad in our country, which can satisfy the demand of mechanical industry. In general, the iron used to produce large rolls of galvanized wire can be divided into two classes. A metal exercised directly from the iron ore through the iron making stroke, the composition of the ore is iron oxide, silica and other miscellaneous stones. When this ore is specially refined into metal iron, carbon, silicon, manganese, and other elements are mixed into it. The material produced in this way is called ordinary pig iron, which is also the material for the first grade.
The hot plating wire is made of low carbon steel wire rod, which is processed by drawing forming, pickling and rust removal, high temperature annealing, hot dip galvanizing and cooling. Galvanized iron wire has resistance and elasticity, the amount of zinc can reach 300 g/square meter, with thick galvanized layer, strong corrosion resistance and other characteristics. Widely used in construction, handicrafts, wire mesh, highway guardrail, commodity packaging and ordinary civilian and other fields.
Traditional barbed wire is crisscross woven into the wire, with the development of the economy, the rapid rise of all walks of life, the limitations of the use of traditional barbed wire gradually exposed, such as: aquaculture, to the chicken circle cage can not be too dense, the wire can not be too thick, woven mesh wire once the mesh will become soft. We also have coping methods: 1, cotton gouging, rolling straight wire into wavy shape, but still not enough to raise chickens with mesh can only be extended to the beak can not feed! 2, is the electric welding net, with the current of the longitude and weft wire spot welding together, the mesh is not limited to do more.
Some raw materials in the production of unstable processing, the wire itself will exist burr, surface small pits and other local defects. Galvanized steel in galvanized, generally should pay attention to the galvanized layer protection time of galvanized wire, and the thickness of galvanized layer has a great relationship. Generally speaking, when the main gas is relatively dry and used indoors, the galvanized layer thickness of galvanized wires is only 6-12μm, and under relatively harsh conditions, the galvanized layer thickness of galvanized wires needs 20μm, and can be predicted to reach 50μm.
