- D, coating adhesion; The zinc layer of the plating parts should be firmly combined with the base metal with sufficient adhesion strength, and will not fall off or bulge after the hammer test.
The design is designed not only for ease of installation, but also for the ability to achieve such installation in harsh terrain conditions such as cliffs, with little anchorage and little excavation for quick and easy installation. Based on the characteristics of heavy hexagonal mesh double stranded structure, even in the case of wire damage can also withstand the impact of falling rock.
Post time: 23-11-22- 2. Dissolution treatment: Put the pickling steel wire into the dissolution tank, and dissolve the zinc powder with the bath liquid by heating, and the dissolved zinc liquid will adhere to the surface of the steel wire.
- The key and important parts with tensile strength greater than 1034Mpa should be relieved of stress at 200±10℃ for more than 1 hour before plating, and the carburized or surface hardened parts should be relieved of stress 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.
Large roll of galvanized wire alloy elements in iron ore, can make copper through the material thickening degree of strengthening, hardness, impact force, strength resistance, closing rate, elongation, so alloy iron in the exercise of good iron, is an important supplementary element. The difference between galvanized wire and general iron wire is very big, general iron wire is cheap, and because iron is not very stable, easy to rust in wet places, so the stability is not very good, life is not very long.
- 2. Preheating: Put the steel wire into the preheating furnace to increase its temperature in order to better react with the molten zinc liquid.
The iron wire used for the barbed wire is woven or welded into low carbon steel wire, medium carbon steel wire, high carbon steel wire, stainless steel wire and other materials. Production process: general braided, embossed braided and spot welding. If the material is steel wire, after equipment processing into a network, it is called wire mesh.

To introduce the relevant information should be very clearly know the highway guardrail net, hexagonal wire netting in all kinds of fence netting, in the value of the high-speed on the road more MaoJian, it not only be used in all kinds of road, in a sports ball games venue and try our best to take care of landslides, also has reached very matter effectiveness.
Post time: 30-09-22- Post-plating treatment (passivation, hot melting, sealing and hydrogen removal, etc.) for the purpose of enhancing protective properties, decoration and other special purposes. After galvanized, chromate passivation or other conversion treatment is generally required to form the corresponding type of conversion film, which is one of the key processes to ensure the quality of post-plating.
6, passivation to remove hydrogen parts should be passivation after the removal of hydrogen, passivation before the application of 1%H2SO4 or 1% hydrochloric acid activation 5~15s. Passivation shall be treated with colored chromate unless otherwise specified in the design drawings.

Post time: 11-10-22The 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.
- 4: spray blade barbed rope long service life.
Take 20cm galvanized wire for acid fog experiment, check the zinc content of galvanized wire through the balance to see whether it meets the zinc layer standard required by customers, ensure that the metal wire achieves the role of rust and corrosion prevention, and meet the service life required by customers. Galvanized iron wires must be packed in good condition, bound neatly and orderly, and bound inward to prevent scratches during transportation. The inspection standard of galvanized iron wire also includes the tensile test, which is decided according to the material of the galvanized wire order ordered by the customer, and it needs to be tested by comparing the raw material list.
Post time: 29-06-22The main reason for the high price of stainless steel barbed wire is that the raw material used in the barbed wire is more expensive, because the nickel in it makes it corrosion resistant and ductile. Stainless STEEL BARBED ROPE IS a new type of protective products, precisely because of its corrosion resistance in coastal or often acid rain landing site is widely used, the service life of up to 15 years.
In the thorn rope manufacturer, there are also great differences between hot galvanized thorn rope and cold galvanized thorn rope.
- Galvanized iron wire has excellent endurance and elasticity, zinc can reach 300 grams/square meter. It has the characteristics of thick galvanized layer and strong corrosion resistance. Widely used in construction, handicrafts, wire mesh, highway guardrail, commodity packaging and ordinary civilian and other categories.
We must have a certain understanding of the hexagonal network, we are the beautiful shape of the hexagonal network, more than the appearance of the hexagonal network is very beautiful, in fact, the practical value of survival is very high. To introduce the relevant information should be very clearly know the highway guardrail net, hexagonal wire netting in all kinds of fence netting, in the value of the high-speed on the road more MaoJian, it not only be used in all kinds of road, in a sports ball games venue and try our best to take care of landslides, also has reached very matter effectiveness.
Paint on the galvanized layer, the binding force between each other and the baking temperature of the paint has a great relationship, after galvanized coating alkyd paint, adhesion is no problem. Galvanized amino paint, paint adhesion is not good. Do two bottom two surface, adhesion is ok, if the two bottom two surface to two bottom three surface, that is, more paint, more baking once, again test adhesion is very poor, poor to the paint from the galvanized layer of pieces torn off.
The formation process of hot dip galvanized layer is between the iron matrix and the outside of the pure zinc layer, the formation of iron-zinc alloy process, the workpiece surface in hot dip plating when the formation of iron-zinc alloy layer, so that the iron and pure zinc layer is well combined. The process of large roll galvanized wire can be simply described as: when the iron workpiece is immersed in the molten zinc liquid, the first zinc and α-iron (body-centered) solid melt is formed on the interface. This is a crystal formed by the matrix metal iron dissolved with zinc atoms in the solid state. The two metal atoms are fused with each other, and the attraction between the atoms is relatively small.
Steel wire and iron wire have a lot of similarities, but carefully distinguish, you will find that they are not only different in the material, but also in the product characteristics are very different. So when choosing, make sure you make a clear distinction between the two. Steel wire factory introduces steel wire carbon structure steel made above, generally not galvanized, used for machinery, spring. Black and hard; Iron wire: low carbon steel (mild steel), galvanized, used for joining and wrapping. It’s white and soft.
