Post time: 14-10-22Cold galvanizing (galvanizing) is in the plating tank after the current unidirectional, so that the zinc gradually plated on the metal surface, slow production speed, uniform coating, thin thickness, usually as long as 3-15g, bright appearance, poor corrosion resistance, usually a few months will rust. Compared with hot dip galvanizing, the production cost of electric galvanizing is lower.

- 3. Scope of application. Electrogalvanizing involves more and more extensive fields, fastener products have been widely used in machinery manufacturing, electronics, precision instruments, chemical industry, transportation, aerospace and so on in the national economy is of great significance.
3, reduce the bivalent iron ion in the plating aid used for hot plating wire, reduce the formation of zinc slag
Post time: 26-04-23The use of steel mesh saves a lot of on-site binding and construction site, can end civilized construction, advance the quality of steel structure engineering. Because the steel mesh is prefabricated in the factory, there is no need for site reprocessing, and there is no need for steel chips, because the construction cycle is shortened, and the cost of lifting machinery is reduced.
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.
Nemesis roller cage is used for the isolation and protection of pasture distance, railway and highway, as well as the enclosure and protection of garden apartment, government units, guard posts and border defense. The Nestor rolling cage is fixed with Nestor connecting card at intervals of 120° after the blade barbed rope is wound around the cage. After opening, the Nestor connecting card is formed into a snake belly network. After closing, the diameter of the blade barbed rope ring is 50cm.
- 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.
- 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.
- 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.
- The main raw materials of blade barbed wire are galvanized wire and galvanized sheet. Because the price of galvanized sheet is more expensive than galvanized wire, it is directly reflected in the price of blade barbed wire sales. There is also the difference in processing technology also leads to the difference in the price of the blade barbed rope. The traditional barbed rope is mechanically twisted, with relatively small labor consumption and high production efficiency. But the blade barbed rope is after the second mechanical processing in the artificial processing operations to appear. Therefore, there is a big gap between labor force and production efficiency. These factors lead to the price of the blade barbed rope is more expensive main factors.
In view of this situation, many manufacturers are committed to ensuring the corrosion resistance of titanium and titanium alloy under the premise of increasing the hardness of titanium alloy, and surface carburizing is one of the typical processing technology means. Similar to the surface carburizing treatment of steel, the surface carburizing treatment of titanium alloy is to make the active carbon atoms, diffusion to the internal of titanium alloy, the formation of a certain thickness of higher carbon content of the carburizing layer, after quenching and tempering, so that the surface layer of the workpiece to obtain high carbon content of titanium alloy wire.
- Galvanized wire often turns black, affecting its beauty. In the process of galvanized, attention should be paid to the air, impurities in the production of steel plate and the health of construction personnel. In fact, it is the problem that will affect galvanized wire. Some simple treatment methods can prevent galvanized silk from turning black or extending the time of turning black in the process of making it, such as: keep the work site dry, reduce and do not use chemicals, and the operator with clean gloves.

Post time: 07-09-22Large hexagonal net called the stone cage net. Stone cage net before delivery, must be folded into a simple surface, packed compression after delivery. Then put it into the right position to open, and then put the appropriate size of the stone into the cage, the lid tight, and then the various stone cage net and adjacent stone cage net tied up.
Post time: 05-01-23During this process, each time the wire is pulled over, the surface hardens due to the high friction temperature. So basically every time you pull it you have to annealing it in the furnace. On the one hand, it is to reduce the surface hardness. On the other hand, during the process of wire pulling, only the surface is deformed, and the center is unchanged. So there’s a lot of stress inside. Therefore, it is necessary to rely on annealing to eliminate the internal stress, so that the wire becomes soft again to eliminate the stress before being drawn again.
The characteristics of hexagonal wire mesh: strong structure, flat surface, with good corrosion resistance, oxidation resistance and so on.
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 machine, we can generally judge whether the quality of galvanized wire is high quality.
- According to different body shape, habits, bird cage can be divided into many species. The basic components of the bird cage are plate top, cage rack, cage bar, cage door, cage hook, dragon ring, bottom ring, bottom of the cage. The accessories are composed of poop board, sun bar, bird food pot, water tank, jade finger, horsetail string and so on.
Post time: 09-10-22And high quality data is constrained by production cost and production conditions, so some welding mesh manufacturers do not meet this requirement, natural in this case, there is no way to improve the strength of the product. In addition to the data, there is the production process, even if it is the best data, but the manufacturer does not meet the production process requirements in the welding, it will also form the product under high pressure welding, so this is also a decline in strength, the process conditions of different manufacturers are also very different, so it forms the market above the product has a difference in strength.
There is still some demand for galvanized barbed rope by daily residents, but often the quantity is not particularly much. If the barbed rope factory delivers goods, then the extra freight may be higher than the price of the customer to buy the barbed rope in the market. The thorn rope factory sells to customers who buy in large quantities. There is a lot of demand for it, and it also hopes to find a manufacturer to purchase.
