2, reduce the bivalent iron ion in the plating aid used for hot plating wire, reduce the formation of zinc slag
The hook mesh is a good material for flood control and flooding. Can also be used for arts and crafts manufacturing, mechanical equipment transport network mountain beautification network – high strength steel wire grid (hook mesh, diamond mesh) hook mesh mountain protection application principle, hook mesh interests, mesh uniform, flat, woven concise, hook woven, beautiful and generous, net, net width, wire diameter is thicker, not easy to corrosion, long life, strong usefulness.

The bonding and anchoring function between the cold rolled ribbed steel bar and concrete is outstanding. In reinforced concrete structure, the width of black iron wire processing crack is smaller than that of circular steel bar, even than that of hot rolled thread steel bar. Therefore, it is used in the component, which fundamentally eliminates the phenomenon of steel wire sliding and damage, and improves the load bearing ability and crack resistance ability of the component end.
Large rolls of galvanized wire in oxygen violently extinguished, spark, and sodium block, magnesium strip in oxygen extinguished, no spark phenomenon. This phenomenon is determined by the composition of galvanized wire. The galvanized wire used in the experiment is pig iron or steel wire, pig iron and steel are iron and carbon alloy, containing iron and carbon two elements of complex material. Carbon in galvanized wire will produce carbon dioxide when extinguished, solid into gas, volume will shrink rapidly.

Post time: 27-06-22There are too many fake things on the market now, so shoppers should learn how to distinguish the quality of galvanized wire, the right to protect their consumers’ rights and interests. Galvanizing process of galvanized wire products is a very effective metal anticorrosion method, and it is also widely used in other industrial fields. After galvanizing, iron wire is commonly used in metal structure equipment of various industries.
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.
1. Electroplating process control
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.
The most common barbed rope is 14*14 and 12*14 wire diameter barbed rope. The 14*14 wire diameter barbed rope is made of 200mm galvanized wire, and the barbed distance can be directly adjusted from 8-12cm. According to the different needs of each customer processing customized. Similarly, the length of each bundle of barbed rope can be cut from 50-250m as required. The 12*14 standard barbed rope is twisted by two different specifications of galvanized wire for 260mm and 220mm barbed wire. Other parameters are roughly the same except for different wire diameters. The price is slightly expensive because the latter uses more materials.
Large hexagonal mesh called stone cage net, is mainly used for mountain protection, hydraulic construction and so on. Small wire hexagonal mesh is used as a good material for breeding, will twist twist hexagonal mesh in the welded iron frame on the hexagonal mesh welding into chicken coop, pigeon cage, rabbit cage cage cage, hexagonal mesh is the best material for breeding with a net.
3. Acid activation acid activation solution should be able to remove corrosion products and oxide film (skin) on the surface of parts, without excessive corrosion on the matrix.
Therefore, the rust of galvanized black iron wire has a great relationship with storage. At the same time, after rust, it is also necessary to conduct reasonable post-processing to avoid affecting its use effect. Of course, when the black iron wire is galvanized, it is also necessary to ensure the thickness of the galvanized layer, so that it can also reduce the possibility of rust. Speaking of galvanized iron wire, perhaps many people think it is relatively rare, in fact, it is not.
The use of electric welding mesh is very widely, but also used in different industries, different places, many times the name is named because of the use or use, so the use of electric welding mesh is doomed to a variety of different names. Can be called row welding mesh, or zinc plating welding mesh or galvanized welding mesh. There’s also the outer wall wire, which is just used for insulation, usually placed on the outside of the wall, to reduce heat emission.
Post time: 23-06-22The large roll of galvanized wire is violently extinguished in oxygen and sparks radiate, while the sodium block and magnesium bar are extinguished in oxygen and no sparks radiate. This phenomenon is determined by the composition of large rolls of galvanized wire. The large rolls of galvanized wire used in the experiment are pig iron or steel wire, both of which are alloys of iron and carbon (complex substances containing the elements iron and carbon). When the carbon in galvanized wire is extinguished, carbon dioxide will be produced, and the solid will be changed into a gas, and the volume will shrink rapidly.
“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.

Post time: 19-04-23- (4) can withstand a large range of deformation, but still do not collapse. Play the role of fixed thermal insulation;
- Barbed rope often appears in another model: 14*14# barbed rope, 12*12# barbed rope, 12*14# barbed rope, among which the diameter of 14# wire is about 2.0 mm, the diameter of 12# wire is about 2.65 mm, there is a non-standard 2.25 mm is also commonly used line. According to this specification, a kilogram of 14*14# barbed rope is 12 meters, a kilogram of 12*14# barbed rope is 8 meters, and a kilogram of 12*12# barbed rope is about 5 meters.
The prepared black wire welding net is placed in environmental protection galvanized equipment for galvanized treatment. The surface of galvanized welding net is evenly covered with a layer of metal zinc. The corrosion resistance of zinc is very good and it is not easy to be oxidized. The wire diameter error of galvanized welding mesh is very strict, and the gap should be controlled at about 0.02 mm. But whether the tension of an electric welding mesh is qualified, can only be tested by professional tools.
Thus, when zinc is sufficient in a solid melt, the two atoms of zinc and iron disperse with each other. The zinc atoms in the iron matrix are moved into the lattice of the matrix, and the iron elements are gradually formed into alloys. The zinc composition of iron and intermetallic compound FeZn13 in molten zinc solution and the bottom of hot galvanized sheet can be used as zinc slag. The pure zinc layer composed of zinc leaching solution is hexagonal crystal.
Stainless steel barbed rope in the way of corrosion is not too, because the surface is not processed but depends on its own raw materials for corrosion resistance, so there will be no chemical reaction. After a long time of use, will not be similar to hot dip galvanized barbed rope surface corrosion coating problems will rust, because the stainless steel barbed rope internal material and the surface of the material is the same.
Post time: 30-03-23- 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.
