- 2. Preheating: Put the steel wire into the preheating furnace to increase its temperature in order to better react with the molten zinc liquid.
1. Principle. Because zinc does not change easily in dry air, and in humid air, the surface can form a very dense film of zinc carbonate, which can effectively protect the interior from corrosion. And when the coating is damaged for some reason and the matrix is not too large, the zinc and steel matrix form a micro cell, so that the fastener matrix becomes the cathode and is protected. It is widely used in automobile transportation and other industries, but what is needed is the trivalent chromium passivation layer, zinc nickel alloy plating closed coating, reduce the harmful and toxic layer of hexavalent chromium passivation.
- 4, the material requirements of the silk: change wire braid, electric galvanized wire braid, hot galvanized wire braid, first braid after hot plating.

Post time: 22-02-23- 2. The positive and negative twisting barbed wire is cost-effective
Post time: 19-04-23The 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.
- Under normal circumstances, the organic matter contained in galvanized wire can make electroplating speed significantly reduced. 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. Zinc is a silver-white metal, brittle at room temperature, soluble in both acid and base, known as amphoteric metal.
Large volume galvanized wire welding net is made of high quality low carbon steel wire row welding, and then cold plating, hot plating, PVC plastic and other surface passivation, plasticizing treatment, net surface leveling, mesh uniform, welding spot firm, local machining performance is good, stable, anticorrosive, anticorrosive good galvanized welding net types. Galvanized welding net simple and practical judgment quality mainly from the following points:
Post time: 13-12-22- In the process of using hot-dip galvanized wire, we should do a good job of daily overhaul and maintenance, try to avoid the destruction of the surface galvanized layer, and extend the service life of the wire. In addition to user binding, building special electric galvanized shaft silk production factory can also be used to decorate gardens and buildings, make it more beautiful and have higher taste.
Now it is more used in the binding of the construction industry. Compared with ordinary wire, it is also softer and has better luster. Use in daily life does not need to carry out maintenance and maintenance, saving a lot of time, but also save the cost of maintenance and maintenance. Annealed wire has good stability, good corrosion resistance, greatly prolonging the service life. There are many kinds, which can be selected according to different uses. The device for making annealed wire is simple, and the utilization rate of the device is improved. The material properties of annealed wire can meet different processing needs.
Stainless steel barbed wire in the way of corrosion is not too, because the surface is not treated but rely on its own raw materials for corrosion resistance, so there will be no chemical reaction.
The distance between the adjacent two thorn rope installation do not know whether you have noticed? Careful observation can find that its spacing is not the same, the thorn rope factory for customer consultation when asking the installation height of the reason.
Since galvanized iron wire will rust, we need to pay attention in the process of storage and use, try to store in a dry and ventilated environment, in the process of use to avoid damaging the surface of galvanized iron wire, we can slow down the time of galvanized iron wire rust.
Traditional wire mesh is crisscross woven into the wire, with the development of the economy, the rapid rise of all walks of life, the use of traditional wire mesh limitations gradually exposed, such as: aquaculture, to the chicken circle a cage can not be too dense, the wire can not be too thick, woven up the net wire once the mesh is too large net surface will become soft.
- Because of the pre-tension given to the packaging and binding of galvanized wire, it has the excellent characteristics of low relaxation value, small stress loss, good stability after loading, not easy to deformation, no fracture, strong elasticity, ordinary steel lines and rebar are difficult to compare. The use of advanced galvanized finishing process, therefore, the use of hot-dip galvanized steel wire construction, not only good corrosion resistance, but also beautiful and generous. The product has the characteristics of smooth surface, high dimensional accuracy, good uniformity of zinc layer and strong adhesion.
- To stop normalizing or soxhlet processing of wire rod, spheroidization annealing is used instead of large specification. In the middle, especially before the waste drawing process, the thermal disposal of soxhlet is widely used. Prevent decarbonization during thermal disposal. After hot disposal, sulfuric acid or hydrochloric acid pickling is used to remove the iron sheet. Coating can be used to dip lime, phosphating, borax treatment or copper plating.
- Because the bundled galvanized wire is endowed with pre-tension, so it has the excellent characteristics of low relaxation value, small stress loss, good stability after loading, not easy to deformation, no fracture, strong elasticity, ordinary steel lines and rebar is difficult to match. The use of advanced galvanized finishing process, therefore, the use of hot-dip galvanized steel wire construction, not only good anti-corrosion performance, and beautiful generous. The product has the characteristics of smooth surface, high dimensional precision, good uniformity of zinc layer and firm adhesion.
- Galvanized iron wire has tolerance and elasticity, the amount of zinc can reach 300 g/square meter. It has the characteristics of thick galvanized layer and strong corrosion resistance. Widely used in construction, handicrafts, wire mesh, highway guardrail, commodity packaging and ordinary civilian and other fields.
In moist air, a dense basic zinc carbonate film forms on the surface of zinc. Zinc coating belongs to the anodic coating, it is mainly used to prevent the corrosion of steel, its protective performance and the thickness of the coating is very important. The protective and decorative properties of zinc coating can be improved significantly after passivation treatment, dyeing or coating with light protection agent.
The main reason for the high price of stainless steel barbed wire is that the raw material used in the barbed wire is more expensive, because the nickel in it makes it corrosion resistant and ductile. Stainless STEEL BARBED ROPE IS a new type of protective products, precisely because of its corrosion resistance in coastal or often acid rain landing site is widely used, the service life of up to 15 years.
- (3) anti-freezing, residential protection, landscaping protection;
Guardrail in the purchase of how to install the correct is very important, and the installation of guardrail is important, the requirements of height and material are very strict.
- Plastic spraying is also known as electrostatic powder spraying. It is the use of electrostatic attack device to make plastic powder charged, adsorbed on the surface of the iron plate, and then through the baking of 180~220℃, so that the powder can be melted and adhered to the metal surface. Plastic spraying products are mostly used in the indoor box, and the paint film appears flat or matte. Spray powder mainly acrylic powder, polyester powder and so on.
- 2. When there are channels, ponds, lakes and other natural barriers on the side of the road, there is no need to worry about people and animals entering and illegally occupying the road land.
Post time: 25-10-22- 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.
