different types of nails for constructionGenerally, galvanized wire used for welding is required to have a certain hardness. After acceptance of galvanized wire, the first thing to do is to feel the hand, and the other thing is to test on the machine. Because the average user does not have testing equipment, it is also very inconvenient to test on the machine. Use a micrometer to measure the diameter of galvanized wire evenly, and keep it about 0.02mm above and below the contract signing standard, with neat appearance, no leakage plating and no mess.

different types of nails for constructionGenerally, due to wet weather and more precipitation, oxidation and rust of binding iron wire NetEase occurs, so we should better store and use galvanized iron wire to avoid rust as far as possible. About the barbed wire, the surface of the barbed wire attached a layer of galvanized layer, the galvanized layer if too thick will not meet the SGS environmental standards. But if it is too thin, it is easy to oxidize with water molecules and rust.

- 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.
Because the coal resources are exposed on the surface of the open pit coal mine, it is more important to protect and prevent coal theft. The erection and use of barbed rope in these places are better than other products. The barbed rope factory recommends suitable barbed rope products to everyone.
Post time: 13-12-22The 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.
Blade barbed rope production links need to be many times before the finished product, roughly down to four or five links.
The characteristics of galvanized hexagonal net: easy to use; Save transportation costs. It can be shrunk into small rolls and involved in moisture-proof paper packaging, taking up little space. Coating thickness uniformity, stronger corrosion resistance; The construction is simple and does not require special technology; Strong resistance to natural damage and corrosion resistance and adverse weather effects; Can withstand a large range of deformation, and still not collapse. It has the function of fixed heat preservation and insulation.
However, because the bath contains highly toxic cyanide, the gas escaping from the electroplating process will do great harm to the health of workers, and its waste water must be strictly treated before discharge. Galvanized iron wire has good anti-corrosion and anti-rust ability, so it can be used in some outdoor guardrails or fences, especially on handicrafts, which are also of great use. Galvanized iron wire is not easy to rust and oxidation on the surface.
Cold galvanized is in the plating tank through the current unidirectional zinc gradually plated on the metal surface, production speed is slow, uniform coating, thin thickness, usually only 3-15 microns, bright appearance, poor corrosion resistance, generally a few months will rust. Compared with electrogalvanizing, hot galvanizing has lower production cost and less impact on the environment than electroplating.
- In white iron, its carbon and iron phase into iron carbide, crack white, extremely strong and brittle, for the malleable steel material. Alloy grades are made up of various alloying elements with different compositions and structures. Because the alloy element in the iron can make the copper material thick strengthening degree, hardness, impact force, strength resistance, collection rate, elongation rate, so the alloy iron in the exercise of high quality iron, is an additive element.
The protective duration of galvanized iron wire is closely related to the thickness of galvanized iron wire. In general, zinc layer thickness needs to be very high in dry main gas and indoor applications, but in harsh environments. Therefore, in the selection of galvanized layer thickness, the impact of the environment should be considered. If galvanized iron wire products of different diameters are required, material selection and coating should be controlled reasonably.
Because the coastline is generally erected for protection, but often because of environmental factors lead to serious corrosion of the barbed rope lost its function. Stainless steel barbed rope is specially set up to prevent corrosion. Stainless steel barbed rope because the environmental requirements are not very high can be very good protection itself will not have a problem to extend the use of life, so that you can ensure safety.
Post time: 23-11-22In order to pack and bundle galvanized wire on the surface of the deposit layer to remove the surface film, surface inclusion and other defects can be found and treated by conventional technology; Excess foam is caused by soaps and saponable fatty surfactants being brought into the tank. Moderate foam formation rates may be harmless. Small homogeneous particles of large denier present in the tank can stabilize the foam layer. To remove surface active substances by matting with activated carbon. Or filtration to make the foam less stable, which are effective measures; Other measures should also be taken to reduce the intake of surfactant. The electroplating speed can be significantly reduced by the introduction of organic matter. Although the chemical formula is conducive to a high deposition rate, the coating thickness cannot meet the requirements after the organic matter is loaded, so activated carbon can be used to treat the tank.
Galvanized wire can be seen as iron wrapped in carbon. When extinguished, the surface layer is more shallow than carbon can contact with oxygen, produce carbon dioxide gas, and radiate the iron wrapped in it. The more carbon galvanized wire contains, the more obvious the phenomenon of spark. The carbon wrapped in iron acts as if it were an explosive in a charge bag, occasionally blowing the iron apart. Sodium and magnesium contain few flammable impurities, and when extinguished, they just glow.

Post time: 15-06-22With the rapid development of market economy, all walks of life are improving the production process and quality of products, galvanized iron wire industry can not be an exception, of course. However, as a result of galvanized iron wire types differ, its characteristics and production process is also different. Galvanized wire selection of high quality low carbon steel rod processing, is the selection of high quality low carbon steel.
- 3. Before cleaning the cage, put the birds in a safe place, and then clean out the garbage inside the cage. Clean it up with a sweep. Then use a wet rag to clean on site.
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.
The main customers of the thorn rope factory are still targeted at farms and plantations, because the demand for thorn rope is often very large.
- 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.
- The cost of blade thorn rope is much more troublesome than ordinary thorn rope, mainly because the raw materials and processes are more factors.
- The coating on the surface of the welding core is called the coating. The coating of electrode plays a very important role in the welding process. If the photoelectrode without drug skin is used for welding, in the welding process, oxygen and nitrogen in the air will invade a large number of molten metal, metal iron and beneficial elements such as carbon, silicon, manganese oxidation and nitriding to form various oxides and nitrides, and residual in the weld, resulting in slag inclusion or cracks in the weld. The gas in the weld pool may produce a large number of pores in the weld. These factors can greatly reduce the mechanical properties of the weld and make it brittle.
- 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.
When using these two products, it is obvious that there is a gap between them. By pulling or bending the wire, it is often difficult to restore the original, for example, if the same place is repeatedly bent, it will be found that it has broken, and the cold drawing wire will not. Cold drawing wire compared with iron wire, its hardness, tensile resistance, bending ability is greatly enhanced, suitable for building materials.
