First, the effect of tensile strength or hardness of steel wire
Large roll galvanized wire phosphating film is dark gray to black gray, the thickness is generally 5-20μm, has better corrosion resistance in the atmosphere. Membrane is a microporous structure, strong adsorption ability to paint, such as used as paint bottom, corrosion resistance can be further advanced. Metal oxidation treatment: Add steel products to NaOH and NaNO2 mixed solution, heating treatment, the surface can form a layer of thickness of about 0.5-1.5μm blue oxide film, in order to reach the purpose of steel corrosion prevention, this process is called blue treatment, referred to as blue.
The electrode is a kind of material that the coating (that is, the coating) is uniformly and centrally applied on the welding core outside the metal welding core. The electrode is composed of two parts: the welding core and the coating. The welding core is the metal core of the electrode. In order to ensure the quality and performance of the weld, there are strict regulations on the content of various metal elements in the welding core.
With the increasing use of hook mesh, the method of bridge rail is also different. The height of the outer railing of the walkway or seat belt should not be lower than 1.10 meters. The net distance between railings should not be greater than 140 mm and horizontal bar rails should not be used. The planning of the hook mesh is necessary to be safe and reliable, the bolt should be installed on the basis of the railing, its strength should meet the requirements of the standard.
The difference is that hot dip galvanizing is dipped in zinc solution melted by heating, which has fast production speed and thick but uneven coating. The color is dark, the consumption of zinc metal is much, the formation of infiltration layer with the matrix metal, the corrosion resistance is good, and the outdoor environment of hot dip galvanized can be maintained for decades. Cold galvanized is in the plating tank through the current unidirectional zinc gradually plated on the metal surface, the production speed is slow, uniform coating, thin thickness, usually only 3-15 microns, bright appearance, poor corrosion resistance, generally a few months will rust.
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.
Galvanized hexagonal mesh is a kind of galvanized metal wire mesh, the mesh shape is hexagonal.
The impregnated hexagonal wire mesh will lose its original characteristics after corrosion, and will change in shape, color and mechanical properties, resulting in equipment damage, pipeline leakage, etc., specifically, it is easy to break and lose the original protection function. Usually there are three kinds of metal corrosion: physical corrosion, chemical corrosion, electrochemical corrosion, corrosion in addition to the chemical properties and organizational structure of the metal itself, but also related to the surrounding medium, such as wet environment than dry environment easy corrosion, more impurities than impurities less easy corrosion, high temperature conditions than low temperature conditions easy corrosion. After understanding these, we can effectively prevent the corrosion of impregnated hexagonal wire mesh, prolong the service life of products.
Features: Strong flexibility, good plasticity, a wide range of uses process: selection of high-quality low-carbon raw materials, after drawing, annealing processing, soft and strong tensile resistance. The finished product is coated with anti-rust oil, not easy to rust, can be bundled according to customer requirements, each bundle is 1-50kg, can also be made into U wire, broken wire, etc., plastic inside and linen outside packaging, mainly used for binding wire, construction wire, etc.
First of all, we need to pay attention to the material of the barbed wire, because the galvanized barbed wire itself includes cold plating and hot plating. The properties and prices of the two are obviously different, and it is easy to be confused by a little negligence.
Hot dip galvanized hexagonal net is made of low carbon steel wire by mechanized braided welding and then by hot dip zinc treatment. The net color is white and shiny, thick zinc layer, uniform mesh, flat mesh surface, solder joint tension resistance, high corrosion resistance. The surface of the steel wire is usually protected by hot-dip galvanizing, and the thickness of the galvanized protective layer can be made according to the requirements of customers. Hot-dip galvanizing hexagonal net is another kind of twisting mesh corresponding to the galvanizing hexagonal net.
In use, there is no need for daily maintenance and maintenance, not only can save a lot of time, but also can reduce costs, but also has good stability, strong corrosion resistance, greatly prolong the service life. According to the different process is divided into different types, can choose according to their own needs. With good flexibility and elasticity, the main role of annealing wire is to control its degree of softness and hardness, in the production of annealing wire is made of steel wire, now more used in the construction industry binding use, compared with ordinary wire is also more soft, have better luster.
Enclosure to calculate the use of barbed rope, so as to reasonably plan to purchase the amount of barbed rope to facilitate construction
The service life of the original galvanized iron welding mesh is very limited. Generally, good iron railings can only be used for about 2 years, and then renovated until the service life, which is not only time-consuming but also has safety risks. After the appearance of zinc-steel railings, the service life has been increased to a great extent in the post-processing. Generally, it can be used for at least 20 years. To improve the service life of zinc steel railings, we first have a brief understanding of the product characteristics of railings. Then from the maintenance aspect, it is necessary to maintain. Maintenance method of electric welding mesh:
The barbed wire factory will store the blade barbed wire inventory in the appropriate place, because it understands the product characteristics.
The methods to control the thickness of galvanizing are as follows: you can slow down the lifting speed of the workpiece, control the time of galvanizing as far as possible, add the appropriate amount of thinning alloy, reduce the thickness, and improve the temperature of hot-dip galvanizing. But consider the zinc pot, iron pot should not exceed 480 degrees, ceramic pot can be 530 degrees, which can reduce the time of zinc immersion.
Stainless steel barbed wire in the way of corrosion is not too, because the surface is not treated but rely on its own raw materials for corrosion resistance, so there will be no chemical reaction.
Application: Mainly used in communication devices, medical equipment and braided mesh, brush, steel cable, filter screen, high pressure pipe, construction, technical products and other professional electric galvanized wire: is a low carbon steel as core wire, metal composite materials processed by wire drawing, electric galvanized technology.
