- (1) Protect and support seawalls, hillsides, roads and Bridges, river courses and other water conservancy projects;
- Packing and binding galvanized wire is in the liquid state of zinc, after a messy physical and chemical effect, not only on the steel plated thick pure zinc layer, and also generate a zinc-iron alloy layer. This kind of plating method, not only has the corrosion characteristics of the electric galvanized wire, and because of a zinc alloy layer. It also has strong corrosion resistance that can not be compared with electric galvanizing. Therefore, this plating method is particularly suitable for a variety of strong acid, alkali fog and other strong corrosive environment.
The main raw material of blade barbed rope is galvanized wire and galvanized sheet, because the price of galvanized sheet is more expensive than galvanized wire, so it is directly reflected in the price of the sales of blade barbed rope. There is also the difference in processing technology also led to the difference in the price of the blade thorn rope. The traditional barbed rope is mechanically twisted, which uses less labor and has high production efficiency. But the blade is after two mechanical processing in the manual processing operation before the appearance. So whether from the labor force or from the production efficiency also said there is a large gap. These factors lead to the price of blade thorn rope is more expensive the main factor.
One: according to the color of the spray blade thorn rope, its price is higher than the ordinary blade thorn rope 2000-2200 yuan, but the price ratio of the spray blade thorn rope is much higher.
“Dry” hot dip galvanizing is also called “drying solvent method” hot dip galvanizing. Iron and steel work pieces through degreasing, pickling, cleaning, dipping aid solvent and drying, and then immersed in the molten zinc solution to galvanize. The co-solvent is usually hydrochloric acid, ammonium chloride, or ammonium chloride mixed with zinc chloride in aqueous solution.
3. Put zinc block into the plating aid pool regularly, so that the bivalent iron in the plating aid becomes trivalent iron, and it is an important measure to stabilize the PH value in a numerical range. At the same time, it is convenient for the filter to filter out the trivalent iron ions in the plating aid; Ferric ion is controlled between 0.3 and 1.0g/L; When hydrogen is not released in the plating aid, the zinc block is continued. It is an effective measure to reduce zinc slag, improve the fluidity of zinc liquid and reduce the thickness of zinc layer to play the role of plating aid filter.
- Hard black galvanized iron wire is made of low carbon steel wire by wire drawing machine. Hard black galvanized iron wire is the first feature of high hardness, bright appearance. It is mainly used for welding clothes hanger, umbrella, metal mesh, basket, basket and other metal products. Soft black galvanized iron wire is made of low carbon steel wire after annealing and softening, and then cold drawing. Soft black galvanized iron wire is the first feature of good flexibility, slightly higher hardness, bright appearance. Mainly used for metal mesh weaving technology, welding net, process products of welding.
- Generally, 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.
The iron wire used for the barbed wire is woven or welded into low carbon steel wire, medium carbon steel wire, high carbon steel wire, stainless steel wire and other materials. Production process: general braided, embossed braided and spot welding. If the material is steel wire, after equipment processing into a network, it is called wire mesh.
The size of the dog cage is generally small, suitable for indoor small dogs, the dog cage is easy to carry, go out to compare the use, folding dog cage high strength steel wire and steel pipe material, outer spray treatment. Strong texture, excellent rust prevention performance, dog cage inside the tray, can be drawn out, convenient cleaning dog urine and feces, folding, dog cage suitable for family and pet shop multi-pet dog breeding.
Annealing wire is widely used mainly because it has a good elasticity and flexibility, in the annealing process can be a good control of its hardness and softness, it is mainly made of iron wire, more commonly used in the construction industry tie wire use. So why annealing wire according to material properties processing?
Post time: 21-09-22- Long-term exposure to such impurities will result in transition and gap corrosion. The direct solution to this phenomenon is to strengthen the coating of the material to avoid corrosion. Improve the quality of galvanized iron wire, can use the wire that had plated zinc beforehand to pull out when making galvanized iron wire, won’t appear the phenomenon of bad mechanical properties. The toughness of the wire is 15 to 25 per cent higher than that of the drawn and galvanized wire, and in some cases slightly stronger than that of the polished wire.
- Wire mesh depend on own unique strengths are indispensable in building professional, reinforcing crack strengthening anti-cracking material, products with high degree of error is small, uniform mesh, mesh welding, accept ability is strong, not easy deformation, steel wire mesh in different fields have different called, people call it soft steel bar in bridge engineering construction.
- The common barbed rope produced by the manufacturer is the 14*14 type of barbed rope product. Since the warp wire used is the same as the wire diameter of the barbed rope, it is easier to calculate the length and weight. Usually each kilogram of barbed rope can reach about 10 meters of service length. The length of each kilogram of raw material is about 35 meters. Since 35 meters of raw material wire diameter can produce 10 lengths of barbed rope cost.
- 3. The structure of the dog cage should be reasonable
Large coil galvanized wire is made of high quality low carbon steel wire rod processing, is made of high quality low carbon steel, after drawing molding, pickling rust removal, high temperature annealing, hot dip galvanized. Cooling process and other processing. Galvanized wire is divided into hot galvanized wire and cold galvanized wire. Galvanized wire in the process of smelting there are a lot of need to pay more attention to the place, galvanized wire products in the manufacturing process will experience a lot of process, of which the following galvanized wire annealing is a very important step, this step to the nature of galvanized wire has brought a lot of help.
Post time: 14-03-23Galvanized wire to galvanized uniform, a body is now its cross section, the second is the longitudinal uniformity. In the actual operation process, such as the jitter of steel wire, the surface of the pot scum and other reasons will cause galvanized wire surface galvanized layer accumulation, should try to solve the problem.
- Galvanized wire is coated with a layer of stable zinc on the outside of the wire, and the zinc layer is used to protect the wire and make the service life of the wire longer. In the production of galvanized wire, the wire should be pickled. Pickling is to use some acid mist or acid liquid to wash away some oxides on the surface of iron, that is, rust, and some other corrosion, to achieve the purpose of cleaning iron, so that zinc will fall off when galvanized.
In strict accordance with the multi-pass small compression rate drawing, the total compression rate is 96.48%, reducing the scraping of zinc layer. The whole wire drawing die is made of tungsten steel die and polycrystalline die. The Angle of the working cone of the wire drawing die is 12° ~ 16°, and the length of the sizing belt is 0.15 of the diameter of the wire, so as to ensure that the deformation of the zinc layer is basically synchronous with the steel wire substrate.
- 2, galvanized silk mesh forming sheet storage ground should be flat, according to the symbolic needs of regular accumulation, height should not exceed 2M, and away from heat source, avoid exposure.
- First of all, the protective layer of zinc-iron alloy can prevent the steel wire from being corroded by oxidation. The zinc metal reacts with water and oxygen to form a dense zinc oxide layer, which forms a physical barrier to prevent oxygen and water from entering the inside of the steel wire, reducing the chance of corrosion. Compared with ordinary steel wire, hot-dip galvanized wire is more resistant to corrosion in humid, high humidity or corrosive environments such as acid and alkali, so it is more durable.
Post time: 27-10-22With a large pickpocket used for steel wire, into the zinc liquid before the surface of the zinc ash stirring; Use a small outlet for galvanized steel wire; Zinc pot steel wire outlet in 30 minutes, with pickpockets back and forth, until the large, floating zinc residue into brown, real zinc ash, zinc ash surface. The extracted zinc ash should be brown yellow real zinc ash, zinc surface, effectively reduce zinc consumption. This is one of the biggest steps to bring zinc consumption down, and it’s a real problem, one that hasn’t been solved for years.
When the coating of large galvanized wire is blistered in the process of galvanizing, the bath temperature should be checked first. If the bath temperature is not low, and then strengthen the removal of oil before plating, to prevent the base metal in acid corrosion. If you pay attention to these problems, the bubbling phenomenon still exists, it should pay attention to the dosage and quality of additives, then you can stop adding additives, with high current electrolysis for a period of time, to reduce the content of additives, observe whether the bubbling phenomenon is improved. If there is no improvement, check whether the additive has been stored for too long or whether it contains too many impurities.
Post time: 08-05-23Cold wire drawing is a kind of cold processing of metal. The raw material is wire rod, which is produced by peeling, galvanizing and other processes. Galvanized cold drawing is used more in building materials. Its testing standards are also different. The strength of cold drawing is relatively high. Because of the high strength of steel, it plays a very important role in construction. It saves the construction steel in building materials, and also reduces the cost of the project. It also plays a very important role in the structure of concrete.
- The wire after the first plating, its strength limit is also higher than the first plating, plated zinc and then made of wire not only toughness and high strength. There is a lower figure in the strength limit of galvanized iron wire because of the quality of zinc, because the strength of zinc technology is several times smaller than the wire itself. It is difficult to hot-dip galvanize drawn wires, and it is impossible for finer and very fine wires to be coated with the desired thickness of smooth zinc.
