On the contrary, the denser the ion deposition, the better the quality of zinc layer. Under the condition that the surface zinc layer is dense and bright, the quality of zinc layer per unit area should reach 80g/m2, and the process parameters should be optimized as follows: current density is 16-20A /dm2, mass concentration of zinc sulfate solution is 500g/L, and pH value is 2.5-3.0.
When using these two products, it is obvious that there is a gap between them. By pulling or bending the wire, it is often difficult to restore the original, for example, if the same place is repeatedly bent, it will be found that it has broken, and the cold drawing wire will not. Cold drawing wire compared with iron wire, its hardness, tensile resistance, bending ability is greatly enhanced, suitable for building materials.
Widely used in practice, iron wire also has certain harm, simple rust and corrosion, so we can generally use galvanized method to prevent product corrosion. Together in addition to this method, metal commonly used treatment methods and phosphating treatment, oxidation treatment, etc. Metal phosphating treatment: iron and steel products to remove oil, rust, into the specific composition of the salt solution soak, you can form a layer of water soluble salt film on the surface of the metal, this process is called phosphating treatment.
Wire flexibility and elongation is good, can withstand the pressure of mechanical operation, in our country’s industry has played a very important role. There are many kinds of iron wire, the most common is to give black iron wire, galvanized iron wire. The corrosion resistance of the outer coating is effectively improved, but the phenomenon of crevice corrosion will be found after long-term use.
Hexagonal mesh is made of galvanized iron wire woven by automatic mesh machine, mesh into regular hexagonal, mesh standard, beautiful, mesh size can be customized according to customer requirements, usually 27mm,20mm, 13mm, wire diameter from 0.40mm to 1.20mm, to meet the requirements of different customers.
Every time galvanized wire production enters the peak season of the industry, the road leading to the factory will see from time to time transport wire and container vehicles, as well as galvanized bright wire short-distance transport trucks, driving the labor utilization rate in the surrounding countryside, solving the employment problem of most people. Galvanized wire is divided into hot dip galvanized wire and cold galvanized wire difference: hot dip galvanized is in the heated melting zinc liquid dip plating, production speed is fast, the coating is thick but not uniform. Dark color, consumption of zinc metal, and matrix metal formation of infiltration layer, good corrosion resistance, hot dip galvanizing in outdoor environment can be maintained for decades.
