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.

There is no need to carry out daily maintenance and maintenance when in use, which can not only save a lot of time, but also reduce the cost, but also has good stability, strong corrosion resistance, greatly extend the service life. According to the different technology is divided into different types, can be selected according to their own needs, has better flexibility and elasticity. The main function of annealing wire is to control its hardness, when the annealing wire is made of steel wire.

Post time: 08-07-22 - Scope of use: Because the obtained coating is thicker, hot-dip galvanizing has very good protective function than electric galvanizing, so it is an important maintenance coating for iron and steel parts in strict working environment. Hot-dip galvanized products are widely used in chemical equipment, petroleum processing, Marine exploration, metal structure, electric power transportation, shipbuilding and other occupations. In agriculture, such as pesticide irrigation, greenhouse and construction industry, such as water and gas transportation, wire casing, scaffolding, Bridges, highway guardrail and other aspects, have been widely used in these years.
- Some herdsmen avoid the intrusion of wild animals and other people’s livestock and from time to time to increase the grassland grassland stainless steel barbed rope fence net, so that the grassland grassland stainless steel barbed rope fence net has become a barrier to all kinds of wild animals. It is in herders’ interests to increase the number of their livestock, but consciously raising barbed ropes not only directly frightens and harms wildlife, but also cuts them off from food and migration.

Corrosion usually metal corrosion has three types: physical, chemical corrosion and electrochemical corrosion, and corrosion depends on the chemistry of the metal itself and the organizational structure, still have relationship with the surrounding medium, such as wet environment than dry environment is easy to rust, more less than the impurities of impurities is easy corrosion, high temperature conditions than under the condition of low temperature corrosion, etc. After knowing these, we can effectively prevent the corrosion of the dip plastic six side wire mesh, prolong the service life of the product.

There is also a straight blade stabbing rope, which is mainly because the board and wire are not wound in the process of wrapping, so the blade stabbing rope produced is a straight product. The length of the barbed rope of this specification cannot be too long due to the limitation of logistics, and it cannot be bent because it is easy to be deformed by force. This is also the main reason why the barbed rope of the straight blade is not whole or long. Customers are advised to determine the spacing before purchase to prevent losses caused by no calculation.

The main difference is carbon content. Iron has a carbon content of 2.11 percent or more, while steel has a carbon content of 2.11 percent or less. Iron-carbon alloys with carbon content of more than 2.11% are cast iron (pig iron), which are basically not malleable and cannot be drawn into wire. Secondly, the content of impurities is different, and the content of harmful impurities such as sulfur and phosphorus in steel is smaller. Wire general color key, wire color light point, white point.
- With a large pickpocket used for steel wire, into the zinc liquid before the surface of the zinc ash stirring; Use a small outlet for galvanized steel wire; Zinc pot steel wire outlet in 30 minutes, with pickpockets back and forth, until the large, floating zinc residue into brown, real zinc ash, zinc ash surface. The extracted zinc ash should be brown yellow real zinc ash, zinc surface, effectively reduce zinc consumption. This is one of the measures to reduce zinc consumption, but it is also a real problem, which has not been solved for many years.

In general, the hardness of a metal is often considered to be the resistance of the material to plastic deformation, scratches, wear, or cutting. In the debugging of zinc wire dipping distance, keep the original speed unchanged, according to the time of dipping zinc, the diameter of steel wire, and then estimate the dipping distance. By adjusting the zinc immersion distance, the zinc immersion time of steel wire of various specifications is shortened by 5s on average compared with that before debugging, so that the zinc consumption per ton of steel wire is reduced from 61kg to 59.4kg.

Post time: 07-06-24 - Three points should be selected before installation, which are the highest point (lowest) and the side line on both sides. The number of thorn rope column is good. When installing, it can be installed gradually according to the hook arrangement of thorn rope column.

Large roll galvanized wire is simply galvanized iron wire, usually used wire is often visible, because iron is very easy to be corroded and rusted, so it is necessary to put a layer of other not easy to rust metal plating in the outer layer, to achieve the effect of corrosion resistance and rust resistance, the effect of zinc can do more. Therefore, many customers often require hardware factories to produce galvanized iron wire, which requires the use of galvanized iron wire equipment.

Large roll galvanized wire is processed from high quality low carbon steel wire rod. Each wire rod rolled by continuous rolling mill is not less than 200kg, but 15% of the number of plates in each batch is allowed to be composed of two, of which the weight of each rod is not less than 80kg, and 4% of the number of plates in each batch is allowed, and the mass of its single wire rod is less than 200kg, but not less than 40kg. Each rod rolled by semicontinuous mill shall not be less than 60kg, and each batch shall be allowed to have 5% disk nitrogen. The mass of the rod shall not be less than 60kg, but not less than 30kg.

Galvanized wire coating has galvanized, aluminum, nylon or plastic coating. Zinc plating is divided into thin coating after steel wire plating and thick coating after steel wire drawing. The mechanical properties of thick coating are lower than that of smooth steel wire rope, and it is suitable for use in serious corrosive environment. Aluminized wire rope it is more resistant to corrosion, wear resistance, heat resistance than galvanized wire rope, using the method of production after the first plating. The wire rope coated with nylon or plastic is divided into two kinds: coated rope and coated rope.
