  • Hot dip galvanizing is in the hot melt zinc liquid dip plating, production speed, thick but uneven coating, the market allows the thickness of 45 microns, up to 300 microns above. It is dark in color, consumes more zinc metal, forms infiltration layer with base metal, and has good corrosion resistance. Hot dip galvanizing can be maintained for decades in outdoor environment. The protection of zinc coating on iron matrix has two principles: on the one hand, although zinc is more active and easy to oxidize than iron, but its oxide film is not as loose and compact as iron oxide. The dense oxide layer formed on the surface inhibits the further oxidation of zinc in the interior.
  • 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.

  • If the surface of galvanized wire hair black, galvanized layer is thin and uneven, this galvanized wire is partly because the inventory storage time is longer, it may also be because the production technical requirements of galvanized wire, do not meet the standard standards and lead to galvanized wire quality problems. According to the use of galvanized wire is different, galvanized wire has soft and hard, so the galvanized wire for binding requires the flexibility of galvanized wire is better, the flexibility of galvanized wire is good, which can facilitate the operation of workers.

  • Wire mesh welding after galvanized is through the end of the welding and then the cold company to make wire mesh wire mesh steel mesh construction mesh floor heating mesh galvanized or hot galvanized. After the first galvanized welding is to change the wire mesh, after the end of welding can see the welding spot; The two processes are different prices are also very different, the cost of the first plating after welding is low, the appearance is smooth, and the cost of the first welding after plating is higher, not easy to rust.

  • The electrode is a kind of material that the coating (that is, the coating) is uniformly and centrally applied on the welding core outside the metal welding core. The electrode is composed of two parts: the welding core and the coating. The welding core is the metal core of the electrode. In order to ensure the quality and performance of the weld, there are strict regulations on the content of various metal elements in the welding core. Electrode structure: portable non – electrode, including cylinder, tube, sleeve plug. The electrode is made of metal or metal oxide powder, such as high heat agent and additives. Paper tube is generally used for drug pipe, and metal tube can also be used for different welding parts and use environment. The plug is at the end of the electrode, which is the clamping part that matches the sleeve during welding and prevents the flux from leaking out of the tube.

  • 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 welding core is the metal core of the electrode. In order to ensure the quality of the weld, there are strict regulations on the content of various metal elements in the weld core. In particular, there are strict restrictions on harmful impurities (such as sulfur and phosphorus), and the quality of the weld core metal should be better than that of the base metal. Arc welding cannot be carried out on a smooth rod without a coating. This is because the arc stability is very poor, splashing is very large, and the weld is not well formed. After long-term practice, it is gradually found that the performance of the electrode is greatly improved by coating the welding core with some mineral raw materials (i.e. electrode coating). (1) Ensure stable arc combustion, so that the welding process is normal. (2) Using the gas produced after the drug skin reaction, protect the arc and the molten pool, prevent the harmful gases in the air (such as nitrogen, oxygen, etc.) from invading the molten pool, such as these gases will cause cracks and pores in the welding material, so that the welding can not achieve the ideal effect. (3) After the drug skin is melted, slag is formed, which covers the weld surface to protect the weld metal, make the weld metal slowly cool, help the gas escape, prevent the generation of pores, and improve the structure and performance of the weld. (4) After melting, various metallurgical reactions will be carried out, such as deoxygenation, sulfur removal, phosphorus removal, etc., so as to improve weld quality and reduce alloying element burning loss.

  • The price of galvanized iron wire is relatively low, but the corrosion resistance is excellent, so it is favored by many screen businesses. In the production process of galvanized iron wire, first of all, we should check the equipment to see if there are any problems, and then we should look at the galvanized process, whether there are factors that cause product discoloration. If these problems do not exist, or some of them occur on the same equipment, and some are normal, then we should consider the problem of raw materials at this time.

  • Galvanized hook mesh selection of low carbon steel wire, the surface of cold galvanized or hot galvanized anticorrosive treatment, strong mesh, strong protection, long anticorrosive time. Galvanized wire hook nets are widely used, widely used in warehouses, refrigeration between things, protective reinforcement, parks, zoos, Marine fishing fences and construction site fences, mechanical equipment protection.

  • If the solder joint is too deep, it is not good, although the welding is more solid, but the bearing capacity of the solder joint is greatly reduced, once the pressure exceeds the load range, it will fracture at the solder joint, so it is more dangerous to use. Large galvanized wire production process of low carbon steel wire cleaning cleaning agent, should have no effect on the binding force of the coating, no corrosion of low carbon steel wire. Production process, acid activation acid activation liquid, should be able to remove the surface of low carbon steel wire corrosion products, oxide film, no corrosion to the matrix.

  • No matter how old dogs are, they seem to love to touch noses with people and other animals. In fact, dogs touch noses as a way of socializing, just like humans shake hands and hug when they meet. But dogs don’t nuzzle every human or every animal. They pick and choose who to nuzzle. If they don’t like you, or don’t know you at all, they won’t touch your nose. However, adult dogs will touch almost every puppy’s nose, and they will not only touch the puppy’s nose, but also smell the puppy’s body.

  • If using common galvanized barbed wire due to the influence of climate and environment, will accelerate the corrosion rate of barbed wire lower utilization rate, so use stainless steel barbed wire in coastal areas is the best choice, if it is the environment is dirty it is recommended to use stainless steel barbed wire of nickel content in the highest 316 l, so that you can extend the service life, greatly enhance the protective effect.

  • 2. Preheating: Put the steel wire into the preheating furnace to increase its temperature in order to better react with the molten zinc liquid.

  • When the barbed rope is installed in different places, the choice of barbed rope column is different. Usually, the barbed rope column we install is cement column, but the use of cement column also has its drawbacks. For example, it’s not so convenient if we install it on a steep hill where transportation is not very convenient. This time can use barbed rope with the composite column to install.

  • Application scope of hot wire: Because the coating is thicker, hot galvanized has better protective performance than electric galvanized, so it is an important protective coating for steel parts used in harsh working conditions. Hot galvanized products in chemical equipment, petroleum processing, ocean exploration, metal structure, power transmission, shipbuilding and other industries have a wide range of applications, in the agricultural field such as pesticide irrigation, greenhouse and construction such as water and gas transmission, wire casing, scaffolding, bridge, highway guardrail and other aspects, in recent years has been widely used.
