The life of the “wire”, is actually “low carbon steel wire”, carbon content in less than 0.2%. The surface is usually coated with zinc plating because it is easy to rust. Under atmospheric conditions, the galvanized layer will not rust before most of the fall off, relatively soft. The life of the “steel wire”, is carbon content in about 0.6% of the “carbon steel wire”, or carbon content in about 0.8% of the “high carbon steel wire”, they have enough hardness and elasticity after appropriate heat treatment, high strength. Uses such as winding ordinary spring and so on.

In order to pack and bind galvanized wire in the surface of the sedimentary layer to local removal of surface film, surface inclusion and other defects can be found and treated by conventional technology; Excess foam is formed when soap and surfactants such as saponified fats are brought into the tank. Moderate rates of foam formation may be harmless. Small, homogeneous particles of large denier present in the bath can stabilize the foam layer. Use activated carbon mat to remove surface active substance. Or through filtration to make the foam is not too stable, which are effective measures; Other measures should also be taken to reduce the amount of surfactant introduced. The electroplating speed can be obviously reduced by the addition of organic matter. Although chemical formulations facilitate high deposition rates, the deposition of organic matter does not meet the requirements of coating thickness, so activated carbon can be used to treat the bath.

Breeding cattle and sheep with barbed rope effect is better, because the advantages of barbed rope are more. So the thorn rope used to do animal husbandry effect is good?

The production process of large rolls of galvanized wire is a level of drawing, through the mold into a slightly smaller diameter than the original. And so on down to the desired length. One pull is not desirable, must be numbered, from coarse to fine is dependent on metal ductility. If it changes too much it just breaks. After drawing to a certain diameter, galvanized, so that the finished product.

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.

Therefore, when zinc reaches saturation in the solid melt, the two elements of zinc and iron atoms diffuse with each other, and the zinc atoms diffused into (or infiltrated into) the iron matrix migrate in the lattice of the matrix and gradually form an alloy with iron, while the iron diffused into the molten zinc liquid forms an intermetallic compound FeZn13 with zinc and sinks into the bottom of the hot-dip galvanized pot, that is, zinc slag. When the workpiece is removed from the zinc leaching solution, the surface of the pure zinc layer is formed, which is hexagonal crystal, and its iron content is not more than 0.003%.

With the increasingly extensive use of hook mesh, the method of bridge rail is also different. The height of sidewalks or seatbelt outer railings should not be lower than 1.10 metres. 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.

Cold galvanizing is also called electric galvanizing. It is the use of electrolytic equipment to remove oil, pickling, and then put the pipe into the solution of zinc salt, and connect the anode of the electrolytic equipment, place zinc plate on the opposite side of the pipe, and connect the positive pole of the electrolytic equipment to the power supply. A layer of zinc is deposited on the pipe fitting by directional movement of an electric current from the positive pole to the negative pole. Cold plated pipe fitting is processed before galvanizing.

Stainless steel barbed wire is mainly used in the place near the sea more, wet salty air for metal corrosion is particularly serious, and the selection of stainless steel barbed wire is in order to prevent corrosion.

Strictly control the pH value of large roll galvanized wire bath, research shows that the size of the bath pH value directly affects the quality of steel wire coating, improper control of pH value will cause loose coating. When the pH value is greater than 3, the steel wire coating has burr caused by fine dendrites, and the surface is not smooth. The current density is strictly controlled. From the microscopic morphology, the higher the current density, the larger the zinc layer grain deposition, the less dense the corresponding zinc layer.
