Post time: 22-02-23Strictly control the pH value of large roll galvanized wire bath, research shows that the size of the bath pH value directly affects the quality of steel wire coating, improper control of pH value will cause loose coating. When the pH value is greater than 3, the steel wire coating has burr caused by fine dendrites, and the surface is not smooth. The current density is strictly controlled. From the microscopic morphology, the higher the current density, the larger the zinc layer grain deposition, the less dense the corresponding zinc layer.
Some customers are just for ordinary fencing, but the pictures provided to the barbed rope factory are indeed applied to the barbed rope products in prison, maybe because the customers prefer the style, but such products are really a little overqualified to be installed in ordinary areas. Even if the customers prefer such barbed rope products, the higher price is prohibitive. The price and quality of the prison rope are certainly not the level of the rope we contact in our daily life.
Stainless steel blade barbed wire production process is similar to galvanized blade barbed wire production process, usually according to the mold to determine the size of the blade.
Therefore, when zinc reaches saturation in the solid melt, the two elements of zinc and iron atoms diffuse with each other, and the zinc atoms diffused into (or infiltrated into) the iron matrix migrate in the lattice of the matrix and gradually form an alloy with iron, while the iron diffused into the molten zinc liquid forms an intermetallic compound FeZn13 with zinc and sinks into the bottom of the hot-dip galvanized pot, that is, zinc slag. When the workpiece is removed from the zinc leaching solution, the surface of the pure zinc layer is formed, which is hexagonal crystal, and its iron content is not more than 0.003%.

Post time: 16-11-22Hot wire plating adopts zinc-free slag to add hot molten zinc and galvanizing, which avoids the traditional heating process, radiates 1653 hot molten zinc on surface 4102 of zinc liquid surface, and reduces the high temperature oxidation of zinc liquid surface. At the same time, the heating body is in contact with the zinc liquid, and the heat is directly transferred to the zinc liquid. The utilization rate of heat energy can reach more than 90%, and the heat radiation on the zinc liquid surface is reduced.
- The diameter of welded mesh wire for external walls is generally 2.2-ф4.0, and the mesh is generally 25-50.
Iron products are common metal products in life. Iron products appear everywhere in our life, but there is a big problem in using iron products. Iron products will rust, and when rust occurs, it will affect the use and appearance of iron products. Adding non-metallic coating: clean, dry and coat the surface of iron and steel products with a layer of protective materials, such as oil, mineral grease, rust-proof grease, plastic and lacquer.
- Four: spray blade barbed rope long service life.
- Dip is one of the anticorrosion methods of galvanized diamond net. For hook mesh immersion is one of the methods of anti-corrosion, now the domestic more mature method is: powder immersion method, it originated from the fluidized bed method, the so-called fluidized bed is used in the Winkler gas furnace on the oil contact decomposition, and then developed the solid-gas two-phase contact process, gradually used in metal coating. So sometimes it is still called “fluidized bed coating method”, the actual process is to add the powder coating to the bottom of the porous, breathable container, the blower from the bottom into the treated compressed air, so that the powder coating turned to the “fluidization state”. It becomes a fine, evenly distributed powder.
On the contrary, the denser the ion deposition, the better the quality of zinc layer. Under the condition that the surface zinc layer is dense and bright, the quality of zinc layer per unit area should reach 80g/m2, and the process parameters should be optimized as follows: current density is 16-20A /dm2, mass concentration of zinc sulfate solution is 500g/L, and pH value is 2.5-3.0.
Large hexagonal net called stone cage net, mainly used for mountain preparedness protection, hydraulic construction, etc. Small wire hexagonal net is used as a good material for culture, will twist the hexagonal net in the welding of the iron frame on the hexagonal net welding into chicken cage, pigeon cage, rabbit cage and other cage, hexagonal net is an excellent material for culture with net.
- For key and important parts with tensile strength greater than 1034Mpa, the stress should be removed at 200±10℃ for more than 1 hour before plating, and for carburized or surface hardened parts, the stress should be removed at 140±10℃ for more than 5 hours. The cleaning agent used for cleaning shall have no effect on the binding force of the coating and no corrosion on the substrate. 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.
Galvanized wire can be used zincate galvanized or chloride galvanized and other processes, appropriate additives should be used to obtain the coating required by the standards of low carbon steel wire. When the galvanized wire out of light plating should be carried out light treatment, the galvanized wire bath to control the temperature. Now the quality level of galvanized wire on the market is not equal, galvanized wire is also called hot dip zinc and hot dip galvanized, is an effective way of metal corrosion prevention, mainly used in various industries of metal structure facilities.
- Of course, the quality of any kind of product is also affected by the implementation of the specification by the manufacturer. If the manufacturer of electric welding mesh has no high implementation specification in the production itself, or the procedure specification has declined in the production line, or there is no higher requirement on the production link.
Plastic paint is often see way of electrostatic daub, can be fixed on the periphery of the barbed wire or iron wire board, requires two baidu after heat treatment, make plastic paint or powder coating adhesive on the wire plate, these are painted plastic razor wire is commonly used in indoor boxes, plastic paint surface look overall feeling is very good, strong adhesive force, at the same time is more durable, Coating processing does not take too long, mainly rust prevention and corrosion effect is quite good, much better than the general material.
2. Eliminate caked zinc residue on zinc liquid surface
- Bridge bridge reinforcement is durable in poor function and aging, etc., through the wire mesh reinforcement, can prolong the service life of the bridge, avoiding the phenomenon of bridge cracks, subsidence and so on, wire mesh can play an obvious effect of crack in bridge reinforcement engineering, engineering construction speed, to enhance the crack resistance of concrete function, better economic benefit.

Post time: 02-11-22The different spacing of the thorn rope is mainly in order to save costs to consider, because if they are too close, then obviously a little waste of resources, but the installation is too sparse will not work. Usually the bottom spacing is about 10cm, and the top is up to 20cm, this is because the higher the place is more difficult to climb over, usually more than one meter without the help of tools it is difficult for ordinary people to climb over, and the bottom because of the relatively tight can prevent personnel from drilling in the past.

Post time: 25-10-22Life said “wire”, in fact, is “low carbon steel wire”, carbon content in 0.2% below. The surface is usually coated with zinc coating because it is easy to rust. Under atmospheric conditions, the galvanized layer will not rust before most of the fall off, relatively soft. Life said “steel wire”, is the carbon content of about 0.6% of the “carbon steel wire”, or carbon content of about 0.8% of the “high carbon steel wire”, they have enough hardness and elasticity after appropriate heat treatment, high strength. The use of words such as winding ordinary spring and so on.
- 3. For temporary protection, breeding chickens and ducklings, etc., it is recommended that you choose products with a wire diameter of 2mm.
- Correction is the hot galvanized wire or cold galvanized wire secondary treatment, the surface after correction is smooth and shiny, and the tensile strength is stronger, so that it is not easy to break. Now it is usually used for screen industry will be changed, which can improve the quality. In addition, clothes rack, communication, high voltage line will be changed to prevent breakage.
There 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.
- (4) Stop the use of more than two strands of galvanized iron wire around the operation method.
