Large roll galvanized wire can be divided into hot-dip galvanized wire and cold galvanized wire, the difference between the two lies in the way of zinc and the amount of zinc. Hot dip galvanizing is to soak steel wire in melted zinc liquid, hot dip galvanizing zinc fast, zinc layer thick rust prevention performance is very good, but the zinc is not uniform, and the surface is dark, the life of hot dip galvanizing can reach 20 years.
- Pure zinc is more stable in dry air. In moist air or water containing carbon dioxide and oxygen, the surface will generate a layer of basic zinc carbonate based thin film layer, which can delay the corrosion rate of zinc layer. Comparison of corrosion resistance of zinc coating in aqueous solution of acid, alkali and sodium chloride; It is also resistant to corrosion in atmospheres containing carbon dioxide and hydrogen sulfide and in oceanic atmospheres; In high temperature and high humidity air and contain organic acid atmosphere is small, galvanized layer is also easy to be corroded.
The impregnated hexagonal wire mesh will lose its original characteristics after corrosion, and will change in shape, color and mechanical properties, resulting in equipment damage, pipeline leakage, etc., specifically, it is easy to break and lose the original protection function. Usually there are three kinds of metal corrosion: physical corrosion, chemical corrosion, electrochemical corrosion, corrosion in addition to the chemical properties and organizational structure of the metal itself, but also related to the surrounding medium, such as wet environment than dry environment easy corrosion, more impurities than impurities less easy corrosion, high temperature conditions than low temperature conditions easy corrosion. After understanding these, we can effectively prevent the corrosion of impregnated hexagonal wire mesh, prolong the service life of products.
Maintenance is indispensable in the use of galvanized wire. Large coils of galvanized silk should be coated with oil, fiber core immersion oil, oil is required to protect the fiber core is not rotten, not rust, wire moisture fiber, and from the internal lubrication wire rope. Surface coating so that all wire rope strands in the surface, are evenly coated with a layer of rust-proof lubrication grease, which for friction lifting and mineral water large mine rope, to be coated with grinding and water-resistant black oil grease. Coated with red oil with strong film and good rust resistance, it is required to have a thin oil layer, which is easy to keep clean during operation.
Steel wire and iron wire have many similarities, but carefully distinguish, will find that they are not only different in the material, but also in the product characteristics of the great difference. So when choosing, be sure to make a clear distinction between the two. Steel wire factory introduces steel wire carbon structural steel made above, generally not galvanized, used for machinery, spring. Black, very hard; Wire: made of mild steel (mild steel), galvanized, used for joining and binding. White and soft.
- Most cattle netting is mechanically woven from highly malleable and corrosion-resistant mild steel wire or PVC coated steel wire. Several commonly used raw materials for the manufacture of cattle net are electrogalvanized wire, hot-dip galvanized wire, Galfan steel wire, ten percent aluminum zinc alloy steel wire and the new type of selenium chromium steel wire.
Hook mesh is crocheted with silk heart, its mesh is uniform, flat net surface, beautiful and generous net width, thick silk diameter, not easy to corroded long life, weaving simple, beautiful and useful. Widely used for raising chickens, ducks, geese, rabbits and zoo enclosures. Protection of mechanical equipment, highway guardrail, sports site fence, road beautification with protective net. The screen in the manufacture of a box-like container, with stone filled with the cage, can be used to maintain and support seawall, hillside, road and bridge, reservoir and other civil engineering.
Post time: 31-08-22- 2. Drying: Dry the washed steel wire through hot air or other drying equipment to remove water.
Stainless steel barbed wire in the way of corrosion is not too, because the surface is not treated but relies on its own raw materials for corrosion resistance, so there will be no chemical reaction.
Because there are many large livestock in pasture, and because of the large cost of development and easy to be destroyed by livestock, galvanized barbed rope is the best choice for enclosure. Pasture installation thorn rope is necessary, wire mesh factory to introduce the role of pasture installation thorn rope。
- 2. To avoid galvanized iron wire being gripped by tools like pliers or hardened claws, when the wire suffers from tension or bending stress, scoring or pooping on the surface can lead to damage.
- Used for inner wall welding wire diameter is generally 0.4-ф0.9, mesh is generally 9.5-1.9.
Post time: 04-01-23- Decorative hook mesh size width generally does not span 2 meters. Generally, the length does not span 4m. The length of 2 meters is difficult for workers, and the second is that the galvanized plating is not good. It can reach up to six meters in length, but it doesn’t cross six meters. Generally, the price will increase significantly after 4 meters.
The spring steel wire is made of high carbon and high quality carbon structural steel or carbon tool steel wire rod, and its chemical composition, gas content and non-metallic inclusion must be strictly controlled according to the use of the spring. In order to reduce the appearance of shortcomings and decarbonization layer, the consumption of rod billet to stop surface grinding, if necessary, but also stop peeling.
Hot drawing is the heating before the wire enters the die hole, mainly used for high melting point wire drawing; The temperature drawing is carried out by heating the heater to the range of temperature, mainly used for galvanized steel wire, difficult to deform drawing.
- Determine the size of the crate based on the actual size of the dog as an adult. In general, the cage should be three times the size of the dog’s body, so that the dog has enough room to turn around and so on.
No matter how big they are, dogs seem to love touching noses with people and other animals. In fact, nose touching is a form of social interaction for dogs, much like shaking hands and hugging humans. But dogs don’t rub their noses with every person or animal. They choose who to rub their noses with. If they don’t like you or don’t know you at all, they won’t touch your nose. However, adult dogs will touch the nose of almost every puppy. They will not only touch the puppy’s nose, but also smell the puppy.
Iron products are common metal products in life. Iron products appear everywhere in our life, but there is a big problem in using iron products. Iron products will rust, and when rust occurs, it will affect the use and appearance of iron products. Adding non-metallic coating: clean, dry and coat the surface of iron and steel products with a layer of protective materials, such as oil, mineral grease, rust-proof grease, plastic and lacquer.

Post time: 31-05-22- 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.
Industrial rust prevention method: coated with asphalt, iron roof, coated with asphalt, you can prevent rust. Metal coating: Some metal surface will form a dense oxide film, can be coated on the surface of the metal composed of this metal screen. Such as: galvanized iron, tinplate plating, bicycle underwire and some medical equipment are coated with chromium and nickel.
2, the production and installation is simple and fast, the use of patented friction connection or special connection accessories for installation, greatly improve the installation efficiency.
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.
- Smelting technology is good, advanced equipment, advanced process of large stainless steel plant whether in the control of alloy elements, impurities removal, billet cooling temperature control can be guaranteed, so the product quality is stable and reliable, good internal quality, not easy to rust. On the contrary, some small steel equipment is backward, backward process, smelting process, impurities can not be removed, the production of products will inevitably rust.
- Twisting the barbed wire: twisting the barbed wire in the opposite direction of the main wire. That is, it’s not twisted in one direction. This is called the twisted cord.
