The bonding and anchoring function between cold wire drawing and cold rolled ribbed steel bar and concrete is outstanding. Therefore, when used in components, the phenomenon of cracking of component anchorage area and damage caused by steel wire slip is fundamentally eliminated, and the load-bearing ability and anti-cracking ability of component end are improved. In reinforced concrete structure, the crack width is smaller than that of circular steel bar or even that of hot rolled thread bar.

In strict accordance with the multi-pass small compression rate drawing, the total compression rate is 96.48%, reducing the scraping of zinc layer. The whole wire drawing die is made of tungsten steel die and polycrystalline die. The Angle of the working cone of the wire drawing die is 12° ~ 16°, and the length of the sizing belt is 0.15 of the diameter of the wire, so as to ensure that the deformation of the zinc layer is basically synchronous with the steel wire substrate.

Large roll galvanized wire is the use of low carbon steel wire processing, after drawing forming, pickling rust removal, high temperature annealing, cooling and other processes, in the use of is more widely. The temperature of large roll galvanized wire for electroplating should be controlled at 30 to 50℃. Because the chloride ions in the bath are very corrosive, quartz glass heaters are generally used.

If the zinc coating is good, but in 3% nitric acid when the light, the coating has dark shadow, passivation occurs when the film is brown, may be caused by foreign metal impurities such as copper or lead in the galvanizing liquid. When problems occur in the process of galvanizing large coil galvanized wire, the temperature and current density are checked first, and then the content of zinc and sodium hydroxide in the plating solution is measured and adjusted through the analysis of the plating solution. Whether DPE content is low can be determined by hull cell test.

Hot-dip galvanized wire is widely used in chemical equipment, petroleum processing, Marine exploration, metal structure, electric power transmission, shipbuilding and other industries. It has been widely used in recent years in agricultural fields such as agricultural medicine sprinkler irrigation, greenhouse and construction industry such as water and gas transmission, wire casing, scaffolding, Bridges, highway guardrail and so on.

Defects such as surface film and surface inclusions can be found and treated by conventional techniques in order to remove them locally from the surface of the deposition layer. Excess foam is formed when soap and surfactants such as saponified fats are brought into the tank.

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.

Want to keep a dog friends need to know: choose suitable dog and family environment of the cage, the dog cage to consider the material, the size of the dog, space, location, whether easy to clean and so on. Let’s take a look at these aspects.

The basic thing to choose a pet carrier is to be able to stand up straight inside it, so that your pet can be comfortable, but also need to be able to stretch out all four feet when lying down. Think of your pet as a person, and give it a larger cage where it can move around on one side and sleep on the other. You can use an old blanket for cushions in your pet’s cage, or buy special cushions for pets, as long as they are comfortable.

In use, there is no need for daily maintenance and maintenance, not only can save a lot of time, but also can reduce costs, but also has good stability, strong corrosion resistance, greatly prolong the service life. According to the different process is divided into different types, can choose according to their own needs. With good flexibility and elasticity, the main role of annealing wire is to control its degree of softness and hardness, in the production of annealing wire is made of steel wire, now more used in the construction industry binding use, compared with ordinary wire is also more soft, have better luster.

Annealing wire is widely used mainly because it has a good elasticity and flexibility, in the annealing process can be a good control of its hardness and softness, it is mainly made of iron wire, more commonly used in the construction industry tie wire use. When the wire factory is in production, the annealing wire will be processed according to the performance of the material, and its hardness will be changed according to the different demand, which can make it have more advantages, reduce the consumption of metal and reduce the cost of production.

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.
