Black iron wire application in the process, the main is through the hot metal billet rolling into six point five mm wire rod, and then put it in the drawing into a line of different diameter, the plant and then gradually narrow drawing plate aperture, cooling and annealing, plating process, such as making a variety of different specifications of the wire, the wire compared with ordinary black iron wire, will be more softer, Softness is also very uniform, color is also consistent, widely used in the construction industry, mining, chemical industry, welding mesh, welding coat hanger, reprocessing industry and so on.
3, twist the weight of hexagonal mesh production plant, the greater the weight, the more sufficient the material.
Hot dip galvanizing is also called hot dip zinc and hot dip galvanizing: it is an effective way of metal anticorrosion, mainly used in various industries of metal structure facilities. It is to immerse the steel parts after rust removal into zinc solution melted at about 500℃, so that the surface of the steel members is attached with zinc layer, so as to play the purpose of anticorrosion.

Secondly, the zinc-iron alloy protective layer of hot-dip galvanized wire has self-healing properties. When the surface of hot-dip galvanized wire is damaged or scratched, zinc metal can form zinc ions through electrochemical reaction, self-healing repair of the damaged zinc-iron alloy protective layer, so as to maintain the corrosion resistance of the steel wire. This self-healing property enables the hot-dip galvanized wire to be quickly repaired during use, even if there is a slight scratch or damage on the surface, avoiding further corrosion. After the ordinary steel wire is damaged on the surface, it is often unable to repair itself, which is easy to lead to the diffusion of corrosion and accelerate the aging and damage of the steel wire.
Hot dip galvanized wire is used in carbon structural steel, which is processed by drawing and hot dip galvanized. It is widely used in the manufacture of wire mesh, highway guardrail and construction projects. Electro galvanized wire is a kind of metal conforming material made of low carbon steel as core wire by wire drawing and electro galvanized process. Mainly used in wire mesh, highway guardrail and construction projects.
Packaging and binding electric galvanized wire is in the state of liquid zinc, after messy physical and chemical effects, not only on the steel plating thicker pure zinc layer, and also generate a zinc – iron alloy layer. This plating method not only has the corrosion resistance characteristics of galvanized wire, but also has a zinc-iron alloy layer. It also has strong corrosion resistance that can not be compared with galvanizing. Therefore, this plating method is especially suitable for all kinds of strong acid, alkali fog and other strong corrosion environment.
The first is the cost of raw materials galvanized sheet and galvanized wire, some specifications and waste calculation and so on. Then there is the cost of mechanical processing process and manual processing process. Finally, there is the cost of packing and shipping. In recent years, due to the rapid development of thorn rope manufacturers, so the profit margin of blade thorn rope is not particularly broad.
2, can quickly let the dog develop home habits, let it learn to wait for the owner to take it out, prevent it from making the home dirty, dirty its nest.
Galvanized iron wire has excellent endurance and elasticity, zinc content can reach 300 grams/square meter. It has the characteristics of thick galvanized layer and strong corrosion resistance. Widely used in construction, handicrafts, silk screen preparation, highway guardrail, commodity packaging and ordinary civilian categories.
Atmospheric relative humidity At the same temperature, the percentage of atmospheric water vapor content and its vapor saturation content is called relative humidity. Below a certain relative humidity, the corrosion rate of metal antirust oil is small, while above this relative humidity, the corrosion rate increases sharply.

There are many production links of blade barbed rope, and the finished product can only be produced after several times of production. Roughly, there are four or five links.
Other discarded guardrails can be used as enclosures for cattle, sheep or other domestic animals. It has a good protective effect. Together these robust products do not have a variety of effects on the overall perimeter. It also shows the value of the rich guardrail network in the community, rural cultivation, or cultivation. Although the appearance of barbed wire fence is not safe after abandonment, the protective function will not be affected, so it will not affect the recovery and use.
6, according to the wire diameter thickness to adjust zinc dipping time. Zinc dipping time should be adjusted according to the thickness of wire diameter. The method of adjustment is the length of the distance between the lead screw on the zinc pot and the ceramic sinking roll. The zinc dipping time of coarse wire diameter should be long, and the zinc dipping time of fine wire diameter should be short.
In addition to these reasons, we should also pay attention to the tooling and process must be stable, and regular testing should be done to ensure the uniformity of galvanized layer.

Hot dip galvanizing 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, the formation of infiltration layer with the matrix metal, the corrosion resistance is good, and the outdoor environment of hot dip galvanized can be maintained for decades. Application range of hot dip galvanizing: because the coating is thicker, hot dip galvanizing has better protective performance than electric galvanizing, so it is an important protective coating for iron and steel parts in harsh working environment. Hot-dip galvanized products are widely used in chemical equipment, petroleum processing, Marine exploration, metal structure, power transmission, shipbuilding and other industries, in the field of agriculture such as sprinkler irrigation, greenhouse and construction industry such as water and gas transmission, wire casing, scaffolding, Bridges, highway guardrail and other aspects, has been widely used.
The diameter of cold-drawn wire should conform to the contract, check whether the amount of zinc meets the requirements of the contract, check the tensile strength, and ask the factory to provide the corresponding inspection report. The wire factory introduces that the weight of a single coil of wire of different specifications should not be lower than the volume weight required by the contract, and record the value. No contacts are generated for each reel of wire. If there are contacts, no more than three contacts are generated for each reel. Each contact should be smooth surface treatment, the wire can not be pulled off from the contact, in line with customer packaging requirements.

Many pet cages are designed with a small box in the base, so that pets can clean up when they poop, but also convenient for pets’ health. For example, if there is no excreta box, pet excreta will be on the ground, which is quite unhealthy. If you have a box, it’s easy to take the box out and wash the trash away so it doesn’t get all over the place, so it’s more hygienic.
5. Environmental conditions: Galvanized wire in different environmental conditions, its corrosion resistance may also be different. For example, in acidic environment, zinc layer is easy to be corroded; The corrosion resistance of zinc layer is better in alkaline and neutral environment.
3.Packaging: moisture-proof paper, woven bag, other packaging can be packed according to customer requirements

The small homogeneous particles with large denier in the tank can stabilize the foam layer, but the accumulation of too many solid particles will cause explosion. Coating with activated carbon to remove surfactant, or filtering to make the foam less stable, are effective measures. Other measures should also be taken to reduce the amount of surfactant brought in to Z. The speed of electroplating can be significantly reduced by the addition of organic matter. Although the chemical formulation is conducive to high deposition rate, but the organic matter with the coating thickness can not meet the requirements, so activated carbon can be used to treat the tank liquid.
