Hot dip galvanizing, also known as hot dip galvanizing, is a method of obtaining a metal covering layer by immersing a steel member into a molten zinc solution. With the rapid development of high-voltage power transmission, transportation and communication, the protection requirements for steel parts are becoming higher and higher, and the demand for hot-dip galvanizing is also increasing. Usually the thickness of electrogalvanized layer is 5 ~ 15μm, and the large roll galvanized wire layer is generally more than 35μm, or even up to 200μm. Hot dip galvanized coating ability is good, dense coating, no organic inclusions.
Galvanized steel pipe is divided into hot dip galvanized and electric galvanized. The layer of hot dip galvanized is thick, the cost of electric galvanized is low, and the surface is not very smooth. Used for steel blowing oxygen pipe, generally with small diameter welded steel pipe, specifications from 3/8-2 inches of eight. Made of 08, 10, 15, 20 or 195-Q235 steel strip, in order to prevent corrosion, some should be aluminized.
Hot dip galvanized wire is dipped in zinc liquid melted by heating, with fast production speed and thick but uneven coating. The market allows a low thickness of 45 microns and a high of more than 300 microns. The color is dark, the consumption of zinc metal is much, and the matrix metal forms the infiltration layer, the corrosion resistance is good, the outdoor environment of hot dip galvanized wire can be maintained for decades.
The antisepsis of these materials is very different, the use of life is not the same. Cold galvanized cattle net, also known as electroplating, galvanized amount is small, rust in rain, but the price is cheap, the service life is 5-6 years. The amount of zinc on hot dip galvanizing (low zinc and high zinc) is about 60g to 400g, the service life is about 20-60 years, and the corrosion resistance is general.
What’s the difference between cold galvanized wire and hot galvanized wire? It is mainly different production process. Cold galvanized iron wire, also known as electric galvanized iron wire, is the use of electrolytic galvanizing process, and hot galvanized iron wire is the use of hot penetration galvanizing process. Compared with the two, hot dip galvanized iron wire thick coating, high zinc content, has stronger anti-corrosion and anti-rust effect. Similarly, the price is also higher, cold galvanized iron wire and hot galvanized iron wire which good? Mainly for the use of scenarios and requirements to choose appropriate galvanized iron wire, appropriate is better.
Hexagonal mesh is made of galvanized iron wire woven by automatic mesh machine, mesh into regular hexagonal shape, 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.
There is also a scaly or boride film or oxide. To remove the photosynovium or oxide commonly used methods are: lead grease removal method, acoustic cleaning method, alkali washing or pickling electrolysis grease to oxide method, these methods in the use of gas or steam harmful to human body, pollution, not environmental protection.
Coping methods we also have: 1, gouging, the straight wire rolled into a wavy shape, but still not enough to raise chickens with mesh can only be large enough to extend the beak can not feed! 2, is the electric welding net, with the current to wire spot welding together, mesh is not limited.
