- There is: positive and negative twisting barbed rope high service life
The surface coating of galvanized wire can be seen whether the quality of galvanized wire is good or not. If the strength of zinc attached to the wire is very poor, then this galvanized wire do not buy, because this galvanized wire must be poor galvanized wire. 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, we can generally judge the quality of galvanized wire.
The temperature of large roll galvanized wire should be controlled at 30 to 50℃ during electroplating. Because the chloride ions in the bath are very corrosive, quartz glass heaters are generally used. Continuous production does not need heating, but needs cooling. Cooling can be in the groove side row thin wall plastic pipe, through the flow of tap water cooling, can also be used as a titanium pipe temperature control device.
- Application: Building materials
Annealed wire is mainly through low carbon steel heating, hot drawing, constant temperature and other processes made into soft iron wire, because in the use of different, so there are different in the production process, made of a variety of specifications. Annealed wire can be widely used, mainly because annealed wire and other kinds of iron wire, has many advantages.

In fact, there are not too many kinds of plastic coated thorn rope in color, often seen as grass green and fruit green, export types have white, orange, dark green.
- The optional height of this type of wire mesh is 1 meter, 1.2 meters, 1.5 meters, 1.8 meters, 2 meters. The latter three are the most commonly used, too low to achieve the fence protection effect. The mesh size is divided into 3 cm and 6 cm, and the vast majority of 6 cm is used.
Hexagonal mesh is also known as twisting mesh, thermal insulation net, soft edge net. It is made of single – layer mesh. Its mesh, mesh wire, galvanized and PVC film properties and the same as the cage. This product can be different shapes and sizes of the block stone into the alloy net to form a flexible whole, can be lifted, car, shipping to the designated place, the alloy net connected to each other into a larger whole, construction throwing convenient, fast, good economic performance.
Zinc is a silver-white metal, brittle at room temperature, soluble in acid and alkali, known as amphoteric metal. Pure zinc is more stable in dry air, and small in humid air or water containing carbon dioxide and oxygen. A thin film layer of basic zinc carbonate will be formed on the surface, which can delay the corrosion rate of zinc layer. The corrosion resistance of galvanized layer in aqueous solution of acid, alkali and sodium chloride is relatively strong. It is also not resistant to corrosion in atmospheres containing carbon dioxide and hydrogen sulfide and in Marine atmospheres; In high temperature and high humidity air and containing organic acid atmosphere is small, galvanized layer is also easy to be corroded.
- The material of wire mesh can choose galvanized wire, stainless steel wire, copper wire, coated wire, lacquer wire, etc., different materials are used in different fields, such as construction, culture, decoration, etc.
Zinc adhesion on galvanized wire surface and thickness of zinc layer
Did not do the adhesion test of powder spraying or fluorocarbon spray on the packaging galvanized wire, but there are two points for reference: one, in the sealed or air circulation environment, non-metallic volatiles can corrosion zinc coating; Second, zinc above 230 degrees (c) will brittle the base metal. After powder spraying and fluorocarbon spraying, it is necessary to bake at a higher temperature and in a sealed environment, causing rapid corrosion of zinc, resulting in loose corrosion film resulting in decreased adhesion of coating, and even leading to brittle situation of steel wire.
Abandoned barbed wire guardrail network will generally choose classification pick up, classification gathering pick up and other methods, better to promote the better use of the whole highway guardrail network, abandoned metal guardrail network is still common copper mesh profile.
Galvanized diamond net to reduce the impact of the project on the environment, protect the slope protection area of the land, maintain the rock can be fully strong, slope protection hook net through artificial planting grass planting, the implementation of green function. Suitable for any complex terrain, at the same time, does not destroy the original landform, the product is mesh distribution, visual interference, convenient for artificial afforestation, conducive to the environment, engineering and environment integration system flexibility.
- For single-layer wound non-rotating wire rope, it is necessary to strictly abide by the above principles, otherwise it is easy to cause permanent deformation of wire rope structure; In the case of multilayer winding, the rotation of the rope is determined by the orientation of the reel’s rope groove to lay the foundation for the next layer. The friction between the wire rope and the extrusion pressure of the multi-layer winding drum are large, and the disorderly rope phenomenon is easy to occur. Therefore, the wire rope with a diameter slightly smaller than the pitch of the rope groove and the diameter of the rope groove should be selected to add the touch area between the wire rope and the drum.
- Professional materials in use can meet the needs of most consumers for materials, and the quality of these products is certainly to withstand the test, so if you really can not make up your mind, choose what kind of barbed rope, it is recommended to choose the best blade barbed rope.
Cold plating is a physical treatment method, the zinc is simple and uneven, the amount of zinc is also less than in the corrosion and rust prevention and chemical disposal of hot plating; The amount of hot zinc plating is relatively thick, the surface of the disposal is flat on average, and it is not easy to fall off. A layer of alloy composed of zinc and metal has very strong oxidation ability, and there is a layer of pure zinc on the outside of this layer of alloy, which is why hot plating is thicker and stronger than cold plating. Under the condition of high degree of natural recovery, galvanized hook net can play a very good maintenance effect on the environment, it is not afraid of wind and rain, it is the battle machine in the hook net, much stronger than the dip plastic hook net.
- In cow pen net there are generally pvc covered plastic pvc covered plastic is in the original galvanized steel wire coated with a layer of dark green or gray brown plastic mold, to avoid the corrosion of wire diameter, conducive to the improvement of the corrosion and rust prevention function of wire diameter. So the better the material, the higher the price. Zinc-aluminum alloy cattle net is the best metal net on the market, the price is higher than hot dip galvanized raw materials. The service life is about 80-90 years, and the anti-corrosion function is excellent.
- Every part of the plating can be zinc plated, even in dents, sharp corners and hidden places can be fully maintained. The cost of hot dip galvanized rust prevention is lower than that of other paint coatings. The galvanizing process is more convenient than other coating construction methods, and can prevent the time required after the device is painted on the site. In suburban environment, the standard hot-dip galvanized rust prevention thickness can adhere to more than 50 years without repair. In urban or offshore areas, the standard hot-dip galvanized rust protection layer can last 20 years without repair.
And high-quality data are constrained by production costs and production conditions, so some electric welding mesh manufacturers do not meet this requirement, in this case, there is no way to improve product strength. In addition to data, and produce process, even if again good data, but the factory did not meet the requirements of production process in welding, also can form the product under the high pressure welding, so it is also a kind of strength on the decline, process conditions of different manufacturers also have very big difference, so it formed a shopping mall on the above products are differences of strength.
1, stress relief before plating where the maximum tensile strength is greater than 1034Mpa key and important parts before plating should be at 200±10℃ stress relief for more than 1 hours, carburizing or surface quenching parts should be at 140±10℃ stress relief for more than 5 hours.
With the development of mining industry, pig iron classification in Our country has been very extensive, can satisfy the demand of machinery industry. In general, iron used to produce large coils of galvanized wire can be divided into two classes. A metal produced directly from iron ore and iron smelting, consisting of iron oxide, silicon dioxide, and other miscellaneous stones. When this ore is specially refined into metal iron, carbon, silicon, manganese, and other elements are mixed in, so that the refined material is called general pig iron, is also for the initial grade of the material.
