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.
In order to pack and bundle galvanized wire on the surface of the deposit layer to remove the surface film, surface inclusion and other defects can be found and treated by conventional technology; Excess foam is caused by soaps and saponable fatty surfactants being brought into the tank. Moderate foam formation rates may be harmless. Small homogeneous particles of large denier present in the tank can stabilize the foam layer. To remove surface active substances by matting with activated carbon. Or filtration to make the foam less stable, which are effective measures; Other measures should also be taken to reduce the intake of surfactant. The electroplating speed can be significantly reduced by the introduction of organic matter. Although the chemical formula is conducive to a high deposition rate, the coating thickness cannot meet the requirements after the organic matter is loaded, so activated carbon can be used to treat the tank.

- In the processing of stainless steel barbed wire after cold galvanized or hot galvanized coating on the surface of the last zinc material, not only beautiful but also plays a good protective role.
Wire mesh first welding after galvanized is through the end of welding and then cold this company to produce wire mesh wire mesh steel mesh construction mesh floor heating mesh galvanized or hot dip galvanized. First galvanized after welding is to change wire mesh, after the end of welding can see the solder joint; The two processes are different in price. The cost of plating after welding is low, the appearance is smooth, and the cost of plating after welding is high, and it is not easy to rust.
Post time: 29-05-23- All can do spring can be called spring steel wire, and high carbon is the highest carbon content. Features: WITH high strength and hardness, high elastic limit and fatigue limit (especially notched fatigue limit), cutting function is OK, but welding function and cold plastic deformation ability is poor.
- Large aperture hexagonal net is widely used in mountain, embankment protection, railway and highway isolation barrier, river channel management, soil consolidation berm, water conservancy engineering construction, rivers, DAMS and seawall anti-erosion protection and reservoir river interception, animal husbandry, grassland isolation guardrail, etc.
Post time: 14-10-22Galvanized electric welding mesh refers to the mesh made of zinc alloy material, because of its high strength, high hardness, beautiful appearance, bright color and other advantages, become used in residential communities. Traditional electric welding mesh using iron bars, aluminum alloy materials, need to use welding and other technology, and the texture is soft, easy to rust, single color.
“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.
- 2.25*2.25mm 10 meters per kilogram
- (3) It has a strong ability to resist natural damage, corrosion resistance and adverse climate impact;
- ③ The galvanized iron wire shall not be damaged when it is tightened.
The bonding and anchoring function between cold wire drawing and cold rolled ribbed steel bar and concrete is outstanding. Therefore, when used in components, the phenomenon of cracking of component anchorage area and damage caused by steel wire slip is fundamentally eliminated, and the load-bearing ability and anti-cracking ability of component end are improved. In reinforced concrete structure, the crack width is smaller than that of circular steel bar or even that of hot rolled thread bar.
With the development of mining industry, the classification of pig iron is already very broad in our country, which can satisfy the demand of mechanical industry. In general, the iron used to produce large rolls of galvanized wire can be divided into two classes. A metal exercised directly from the iron ore through the iron making stroke, the composition of the ore is iron oxide, silica and other miscellaneous stones. When this ore is specially refined into metal iron, carbon, silicon, manganese, and other elements are mixed into it. The material produced in this way is called ordinary pig iron, which is also the material for the first grade.
- The above is to extend the service life of stainless steel barbed rope method, mainly to spray and galvanized.
- 1. Cleaning: Soak the pre-treated steel wire in detergent to remove surface impurities and dirt.
The application of black iron wire in the process is mainly through the hot metal billet rolled into 6.5 mm wire rod, and then put it into the wire drawing device into a different diameter line, and then gradually reduce the aperture of the wire drawing disk, cooling and annealing, coating and other processes, made into a variety of different specifications of iron wire, this kind of iron wire and ordinary black iron wire compared, will be softer, Softness is also very uniform, color is consistent, widely used in the construction industry, mining, chemical industry, welding mesh, welding hanger, reprocessing industry.
- Compared with the traditional braided barbed rope, the blade barbed rope has a relatively complex technology and a relatively high cost of raw materials.
The large roll of galvanized wire is like the literal meaning, is wrapped in a layer of zinc on the surface of low carbon steel wire material, beautify the appearance at the same time, but also improve the corrosion resistance of galvanized wire. Zinc dissolves easily in acids and also in bases, so it is called a bi-soluble metal. Zinc changes little in dry air. In moist air, a dense basic zinc carbonate film forms on the surface of zinc.
Cyanogen bath has alkaline zincate bath, ammonium bath, sulfate bath and ammonia chloride bath. Cyanide galvanized solution plating ability is good, the coating lubrication, in production has been selected for a long time, steel mesh chromium plating: chromium plating layer has a high hardness, according to the bath composition and process conditions are different, the hardness can be changed in a large scale 400~1200HV.
