The quality of hot-dip galvanized barbed wire is only the zinc layer attached to the surface of the wire, and with the chemical reaction, the zinc layer on the surface will gradually lose its role because of the oxidation reaction, which is more prominent in the humid environment. And because the use of rusty wire after all, it is said that the quality of hot-dip galvanized barbed wire is certainly not up to the level of stainless steel barbed wire.
2. When there are natural barriers such as canals, ponds and lakes on the side of the road, barbed rope protection nets shall not be set up in the section where there is no need to worry about people and livestock entering and illegally occupying the road land.1. Eliminate caked zinc residue on zinc liquid surface
The material of the blade can be roughly divided into high quality steel wire, galvanized steel plate, stainless steel plate. The general technology used on the blade: hot dip galvanizing – stamping. The blade has the advantages of corrosion resistance, aging resistance, good weather resistance, easy installation, low price and so on. The use of blade rope: Blade rope has been widely used in military sites, prisons, government, banks, residences, private homes, villas, doors and Windows, roads, railway fences and border lines, etc., to ensure safety. Most prisons basically use razor blades.
The characteristics of this kind of small animal cage, is small, light, easy to carry, but also easy to clean care. For small animal cages, 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 “violent”, or the cage under the “destruction” will occur welding or plastic crack off.
3, galvanized wire galvanized processThe lighting surface of each type of shed is designed to be curved, improving the Angle of the light surface, because the lighting surface is curved, no dust accumulation, good light transmittance, high temperature in the shed, after measurement, the average temperature in the shed is 3℃ higher than the traditional bamboo pole cement column shed, the yield is increased by 15~20%, and the harvest date is advanced. The formula is scientific, the surface does not absorb moisture, do not return halogen through modification technology and scientific production process, solve the greenhouse frame rod is easy to absorb moisture return halogen, poor water resistance and easy to change the shortcomings, so that the greenhouse steel pipe in the high temperature and high humidity environment, few drops, frost phenomenon, and reduce pests and diseases.
Some large roll galvanized wire products in order to meet different industrial needs, will be further processed on the surface, such as the anti-corrosion layer, galvanized, iron plating, aluminum alloy plating, or in the galvanized wire appearance above the copper plating, brass plating, etc., to strengthen the steel wire and colloidal years and capabilities. Generally, galvanized wire products should be well plated and drawn when they are produced, and the sequence of the two processes should be decided according to the production or industrial needs.
We must have a certain understanding of the hexagonal network, we are the beautiful shape of the hexagonal network, more than the appearance of the hexagonal network is very beautiful, in fact, the practical value of survival is very high. To introduce the relevant information should be very clearly know the highway guardrail net, hexagonal wire netting in all kinds of fence netting, in the value of the high-speed on the road more MaoJian, it not only be used in all kinds of road, in a sports ball games venue and try our best to take care of landslides, also has reached very matter effectiveness.
High quality galvanized wire in general, the zinc layer attached to the surface of the wire is relatively thick, so when we buy galvanized wire, as long as we look at the thickness of the zinc layer machine, we can generally judge whether the quality of galvanized wire is high quality.
B. When the thickness of the plating is greater than 4 mm, the zinc adhesion should not be less than 610g/m, that is, the average thickness of the zinc layer should not be less than 86 microns.During this process, each time the wire is pulled over, the surface hardens due to the high friction temperature. So basically every time you pull it you have to annealing it in the furnace. On the one hand, it is to reduce the surface hardness. On the other hand, during the process of wire pulling, only the surface is deformed, and the center is unchanged. So there’s a lot of stress inside. Therefore, it is necessary to rely on annealing to eliminate the internal stress, so that the wire becomes soft again to eliminate the stress before being drawn again.
Large coils of galvanized wire are divided into hot dip galvanized and cold dip galvanized. Hot dip galvanized wire is dark in color, consumes more zinc metal, forms infiltration layer with the base metal, and has good corrosion resistance. Hot dip galvanized wire can be maintained for decades in outdoor environment. Cold galvanized production speed is slow, uniform coating, thin thickness, usually only 3-15 microns, bright appearance, poor corrosion resistance, generally a few months will rust.
The wire mesh is composed of low carbon steel wire or medium carbon steel wire, high carbon steel wire or stainless steel wire. There are two kinds of manufacturing technology of steel wire mesh, one is the weaving method, the other is the welding connection, the formation of grid.
The anticorrosion of these raw materials are very different, the use of life is not the same. Cattle fence cold galvanized, also known as electroplating, galvanized little, rust in rain, but the price is cheap, the use of life in 5-6 years. Hot dip galvanizing (low zinc and high zinc) zinc content in 60 grams to 400 grams, the use of life is about 20-60 years, corrosion resistance is general.
