Cold galvanizing, also called electric galvanizing, is the use of electrolytic equipment to remove oil, pickling, after the pipe fitting into the composition of zinc salt solution, and connected to the negative electrode of the electrolytic equipment. Wire factory on the opposite side of the pipe fittings placed zinc plate, connected to the positive electrode of the electrolytic equipment is connected to the power supply, the use of current from the positive electrode to the negative electrode will deposit a layer of zinc on the pipe fittings, cold plating pipe fittings is first processed after galvanized.

In the process of composite electroplating galvanized wire, the plating solution must be stirred to obtain the composite coating in which the particles dispersed in the matrix metal. Stirring methods include mechanical stirring, air stirring, ultrasonic stirring, bath circulation, etc. The acid activation solution in the production process can remove the corrosion products and oxide film on the surface of the low carbon steel wire without excessive corrosion on the matrix.

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.

Common galvanized iron wire equipment is usually used in barbecue net, barbecue net generally requires to have a long service life, with galvanized iron wire equipment to wire a layer of zinc, barbecue net is not easy to be corroded.

Good galvanized wire, plating thickness of 3- 4 mm, zinc adhesion should be less than 460 grams/m, that is, the average thickness of zinc layer is not less than 65 microns. When the thickness of plated parts is greater than 4 mm, the zinc adhesion should not be less than 610 g/m, that is, the average thickness of zinc layer should not be less than 86 microns. Standard galvanized wire coating must be uniform, galvanized layer basically uniform with copper sulfate solution test etching five times no dew iron. For standard galvanized wire coating adhesion requirements, the zinc layer of plated parts should be firmly combined with the basic metal and have enough adhesion strength, after hammer test does not fall off, not convex.

Now it is more used in the binding of the construction industry. Compared with ordinary iron wire, it is softer and has better luster. Use in daily life does not need to carry out maintenance and maintenance, save a lot of time, but also save the cost of maintenance and maintenance. Annealed wire has good stability, good corrosion resistance, greatly prolonging the service life. More kinds, can be selected according to different uses, making annealing wire device is simple, improve the utilization rate of the device. The material properties of annealed wire can meet different processing requirements.

As we all know, the mechanism of resistance to atmospheric corrosion of zinc includes mechanical protection and electrochemical protection. Under the condition of atmospheric corrosion, there are ZnO, Zn(OH)2 and basic zinc carbonate protective film on the surface of zinc layer, which to a certain extent slows the corrosion of zinc. When this protective film (also known as white rust) is damaged, a new film will be formed.

The main raw material of blade barbed rope is galvanized wire and galvanized sheet, because the price of galvanized sheet is more expensive than galvanized wire, so it is directly reflected in the price of the sales of blade barbed rope. There is also the difference in processing technology also led to the difference in the price of the blade thorn rope. The traditional barbed rope is mechanically twisted, which uses less labor and has high production efficiency. But the blade is after two mechanical processing in the manual processing operation before the appearance. So whether from the labor force or from the production efficiency also said there is a large gap. These factors lead to the price of blade thorn rope is more expensive the main factor.

Wire mesh welding after galvanized is through the end of the welding and then the cold company to make wire mesh wire mesh steel mesh construction mesh floor heating mesh galvanized or hot galvanized. After the first galvanized welding is to change the wire mesh, after the end of welding can see the welding spot; The two processes are different prices are also very different, the cost of the first plating after welding is low, the appearance is smooth, and the cost of the first welding after plating is higher, not easy to rust.

The characteristics of these cages are small, light, easy to carry and easy to clean. For small animal cage, the wire diameter of the general iron wire is not very large, the thickness of the plastic is relatively thin, so the use of the time can not be “violence”, otherwise the cage in the “destruction” will occur under the welding or plastic crack.

We contrast the difference between galvanized electric welding mesh and other electric welding mesh by introducing in detail, and the following describes its material: Galvanized welded wire mesh is made of low carbon wire, through automation of fine precision machinery equipment spot welding processing after forming, selection of disposal of the appearance of zinc leaching technology, produce practice British standard, with smooth surface neat, uniform layout to consolidate, the function is good, even if some sections or accept pressure also won’t attack lax appearances, it is the strongest anti-corrosion function in iron mesh, Screen mesh is iron use one of the most widely network class, excellent anticorrosive makes its popularity in the breeding, sucking the neat surface, increased the look and feel, can play will be decorating effect, this feature makes it reflected in the mining industry, because the select material of low carbon high quality material, make it unique iron mesh not usually have flexibility, Concluded that it in the use of plasticity in the process, and then can be used for hardware technology in the deep processing and production, disorderly wall batch swing, underground leakage prevention crack, light mesh body, so that the cost is much lower than the cost of iron screen, more able to understand its economic and practical. Galvanized electric welding net can be used as poultry cage, egg basket, channel fence, drain sink, porch fence, rat net, mechanical shield, livestock and plant fence, grid frame, etc. It is also widely used in industry, agriculture, construction, transport, mining and other occupations.
