Large roll galvanized wire phosphating film is dark gray to black gray, the thickness is generally 5-20μm, has better corrosion resistance in the atmosphere. Membrane is a microporous structure, strong adsorption ability to paint, such as used as paint bottom, corrosion resistance can be further advanced. Metal oxidation treatment: Add steel products to NaOH and NaNO2 mixed solution, heating treatment, the surface can form a layer of thickness of about 0.5-1.5μm blue oxide film, in order to reach the purpose of steel corrosion prevention, this process is called blue treatment, referred to as blue.
- Reverse twist: Twist the barbed wire in the opposite direction from where the nematocyst is wound around the main wire. It’s not twisted in one direction. It’s called the reverse twist.
The quality of hot-dip galvanized barbed wire is only in the surface of the wire attached to the galvanized layer, and with the reason of the chemical reaction, the surface of the zinc layer will gradually lose its role because of the oxidation reaction, this situation is more prominent in humid areas. And because after all, the steel wire will rust, so the quality of hot-dip galvanized barbed wire is certainly not up to the level of stainless steel barbed wire.
Moderate rates of foam formation may be harmless. The presence of small, homogeneous particles of large denier in the tank can stabilize the foam layer, but the accumulation of excessive solid particles can cause an explosion. Using activated carbon mat to remove surface active substances, or through filtration to make the foam is not too stable, this is an effective measure; Other measures should also be taken to reduce the amount of surfactant introduced to Z.
Post time: 14-06-24- The above is to extend the service life of stainless steel barbed rope method, mainly to spray and galvanized.
- The effect of chemical composition and metallographic structure of steel wire
The vertical distance between the lower edge of the Nestor roller cage and the upper edge of the reinforced concrete protective fence is 0.05m. Longitudinal reinforcement adopts hot-dip galvanized netting, double-twist weaving process, barbed wire 2.2mm, main line 2.5mm, netting joint card adopts galvanized steel plate stamping or Q235 carbon steel plate stamping for galvanized.
Compared with galvanizing, hot-dip galvanizing has lower production cost and less environmental impact than galvanizing. Because the coating obtained is thicker, hot-dip galvanizing has better protective performance than electric galvanizing, so it is an important protective coating for steel parts used in harsh working environment. Hot-dip galvanized products are widely used in chemical equipment, petroleum processing, ocean exploration, metal structure, electric power transmission, shipbuilding and other industries.
Post time: 28-01-23In the atmosphere containing carbon dioxide and hydrogen sulfide and Marine atmosphere is not corrosion resistant, in high temperature and high humidity air and contain organic acid atmosphere is small, galvanized layer is also easy to be corroded. In order to make large rolls of galvanized wire on the surface of the deposited layer to the local, remove the surface film layer, surface inclusions and other defects can be found and treated by conventional techniques. Excess foam is caused by soaps and surfactant saponable fats brought into the tank, and moderate rates of foam formation may be harmless.
Post time: 30-05-23The invention technology is used to put zinc block into the plating aid pool regularly, so that the bivalent iron in the plating aid becomes trivalent iron, and plays an important measure to stabilize the PH value within a numerical range, and also facilitate the filter 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.
One is the frame isolation net, guardrail net with frame, frame using material cold plate belt welded into the square tube, usually 2*3 thickness 1.2 thick, the middle for low carbon steel wire welding mesh, wire diameter can choose another welding aperture can also choose, for example, customers want good quality long service time, you can choose thick wire diameter, small welding aperture, Such mesh is not only high quality, but also long service life, customized mesh and frame after welding, surface treatment to reach the customer needs of goods.
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.
Post time: 26-05-22- 3) wire surface coating: some businesses say their pet cage with what stainless steel, in fact, we also know that the price of stainless steel will not be very cheap, most of the cage surface coating is a layer of anti-rust coating, the material is mainly PE powder, but some color is different. The cage of good quality will be cleaned before coated with PE powder, and then baked at a high temperature of 200 degrees, so that PE powder can stick firmly on the wire.
For the wide use of screen, the state has regulations. You also specify the diameter size, mesh size, or usage method. For plastering nets, the mesh should be less than 20 and the diameter should be greater than 1 mm. Not only are specifications specified, but safety is preferred if wire mesh is used in exterior plastering nets. If you fall, the consequences are unimaginable. Therefore, the application of norms should be combined with reality.

Post time: 27-02-23Hexagonal mesh is also known as twisted mesh, insulation mesh, soft edge mesh. It is made of a single mesh reel. The mesh, mesh, galvanized and PVC coated properties are the same as the cage. This product can be different shapes, sizes of the stone into the alloy net to form a flexible whole, can be lifted, cars, shipping to the L place, the alloy net connected into a larger whole, the construction of throwing convenient, fast, good economic performance.
Heavy hexagonal mesh is made of steel wire by special machinery woven hexagonal mesh mesh. This kind of net, after cutting, assembly can be made into fence net, mountain hanging net, vegetation three-dimensional network, combination and so on.
- Purpose of galvanized hexagonal net: building wall fixed, heat preservation, heat insulation; Power plant tied pipe, boiler warm; Anti-freezing, residential protection, landscaping protection; Raising chickens and ducks, isolating chicken and duck houses, to protect poultry; To protect and support seawalls, hillsides, roads and Bridges and other waterworks.
