The electrode is a kind of material that the coating (that is, the coating) is uniformly and centrally applied on the welding core outside the metal welding core. The electrode is composed of two parts: the welding core and the coating. The welding core is the metal core of the electrode. In order to ensure the quality and performance of the weld, there are strict regulations on the content of various metal elements in the welding core.
- Hook net raw materials are basically low carbon steel wire, stainless steel wire and aluminum alloy silk woven, and what are the characteristics and use of these raw materials? Low carbon steel wire is actually the wire we usually use, plasticity is good, good patience, pull is very good.
The characteristics of large volume galvanized wire is smooth and bright surface, but wet will affect the brightness of galvanized wire, so we must pay attention to avoid humidity when storing, can support a shelf on the ground, so that galvanized wire and the ground isolation, so that it will not be affected by the surface moisture, there is to pay attention to the change of weather, to avoid galvanized wire rain. Galvanized wire has good toughness and elasticity, the amount of zinc can reach 300 g/square meter. It has the characteristics of thick galvanized layer and strong corrosion resistance.
- The patented technology is used to regularly put zinc blocks into the plating aid pool, 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 to filter out the trivalent iron ions in the plating aid; The trivalent iron 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 give full play to the function of plating aid filter.

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.
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.
- Pure zinc is more stable in dry air. In moist air or water containing carbon dioxide and oxygen, the surface will generate a layer of basic zinc carbonate based thin film layer, which can delay the corrosion rate of zinc layer. Comparison of corrosion resistance of zinc coating in aqueous solution of acid, alkali and sodium chloride; It is also resistant to corrosion in atmospheres containing carbon dioxide and hydrogen sulfide and in oceanic atmospheres; In high temperature and high humidity air and contain organic acid atmosphere is small, galvanized layer is also easy to be corroded.
Post time: 07-03-23The galvanized layer forms a particular metallurgical structure that is capable of accepting mechanical damage during transport and use. Every part of the plating can be zinc plated, even in dents, sharp corners and hidden places can be fully maintained. The galvanizing process is more convenient than other coating construction methods, and can avoid the required time after the installation on the site.
Pet cage is generally made of high quality iron wire, low carbon steel wire, stainless steel wire welding, which is characterized by beautiful, lightweight, folding, easy to store. The surface treatment of pet cage is generally: cold galvanized, hot galvanized, spray, dip, chromium plating, nickel plating and other methods.
The diameter of cold-drawn wire should conform to the contract, check whether the amount of zinc meets the requirements of the contract, check the tensile strength, and ask the factory to provide the corresponding inspection report. The wire factory introduces that the weight of a single coil of wire of different specifications should not be lower than the volume weight required by the contract, and record the value. No contacts are generated for each reel of wire. If there are contacts, no more than three contacts are generated for each reel. Each contact should be smooth surface treatment, the wire can not be pulled off from the contact, in line with customer packaging requirements.
Post time: 18-04-23- With the progress of the anti-corrosion skills of the cattle fence, the steel wire function of the cattle fence will also improve, so that the life of the progress of the use of great help. The number of years of use is primarily dependent on the environment of use and whether the operation of the construction is standard at the time. The operation standard of progress operation can also extend the number of years of use. The above is a general estimate of the life of the cattle net, I hope to help you.
Post time: 21-12-22The common weight standard of galvanized barbed rope is 25kg per coil, and the length of each coil varies from 220-250 meters according to the specifications of the barbed rope. And of course we all know that the heavier the disc the longer it is. But there is one point that is worth our attention, that is, the hollow inside the general larger disk is relatively small, and the hollow inside the lighter galvanized thorn rope is relatively large. The purpose of this is to reduce the number of bending of the thorn rope and make it easier and more beautiful when installing, on the other hand, it looks larger in appearance.
Post time: 13-04-23- No matter what kind of blade you buy, daily maintenance is indispensable, can prepare some good antirust paint and some rust removal spray, spray antirust paint to the blade rope, so not only beautiful and play the effect of rust, can effectively slow down the process of oxidation, extend its life.
- After a long time of use, it will not rust like the corrosion layer on the surface of hot dip galvanized barbed rope, because the internal material of stainless steel barbed rope is the same as the material on the surface.
The production of large rolls of galvanized wire iron can be divided into two categories, is directly from the iron ore after iron stroke exercise out of the metal, the composition of the ore is iron oxide, silica and other miscellaneous stone.
After electric galvanizing hot galvanizing. Electroplated copper and other common applications of screen consumption. The weaving of the binding of the building steel wire mesh has the first braided after plating, plating after weaving and other methods, after the disposal of the wire mesh or wire mesh has good corrosion, oxidation resistance characteristics, can be used in the construction, petroleum, chemical, aquaculture, garden protection, food processing and other industries of reinforcement, protection and insulation.
- Galvanized iron wire is divided into hot galvanized wire and cold galvanized wire, using low carbon steel wire processing, after drawing molding, pickling rust removal, high temperature annealing, hot galvanized, cooling and other processes. It has good toughness and elasticity, and the amount of zinc can reach 300 grams/square meter. It has the characteristics of thick galvanized layer and strong corrosion resistance. Galvanized iron wire can be cut off in the construction of the tie wire, the length of 20cm, 30cm and 40cm, can be cut off according to requirements.
Common weight length conversion of thorn rope:
- Reverse twist barbed rope: first wrap the barbed wire around the main wire (i.e. a single wire) and then add another wire to twist and weave it into a double strand barbed rope.
If the zinc coating is good, but in 3% nitric acid when the light, the coating has dark shadow, passivation occurs when the film is brown, may be caused by foreign metal impurities such as copper or lead in the galvanizing liquid. When problems occur in the process of galvanizing large coil galvanized wire, the temperature and current density are checked first, and then the content of zinc and sodium hydroxide in the plating solution is measured and adjusted through the analysis of the plating solution. Whether DPE content is low can be determined by hull cell test.
The barbed rope is twined and braided to save transportation space. It is usually wound into bundles.
The life of the “wire”, is actually “low carbon steel wire”, carbon content in less than 0.2%. The surface is usually coated with zinc plating because it is easy to rust. Under atmospheric conditions, the galvanized layer will not rust before most of the fall off, relatively soft. The life of the “steel wire”, is carbon content in about 0.6% of the “carbon steel wire”, or carbon content in about 0.8% of the “high carbon steel wire”, they have enough hardness and elasticity after appropriate heat treatment, high strength. Uses such as winding ordinary spring and so on.
Decorative hook mesh selection of stainless steel, aluminum alloy, brass, copper and other alloy materials, through the special process of preparation of hook mesh. It is a silk screen made of decoration. Today we introduce the aperture and wire diameter of the decorative hook mesh.
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.
- Cold galvanized wire has good toughness and elasticity, high zinc content can reach 300 g/square meter. It has the characteristics of thick galvanized layer and strong corrosion resistance. Cold galvanized wire is widely used in construction, handicrafts, wire mesh preparation, the production of galvanized hook mesh, wall mesh, highway guardrail, product packaging and daily civilian and other fields.
Nemesis roller cage is used for the isolation and protection of pasture distance, railway and highway, as well as the enclosure and protection of garden apartment, government units, guard posts and border defense. The Nestor rolling cage is fixed with Nestor connecting card at intervals of 120° after the blade barbed rope is wound around the cage. After opening, the Nestor connecting card is formed into a snake belly network. After closing, the diameter of the blade barbed rope ring is 50cm.
When the barbed rope is installed in different places, the choice of barbed rope column is different. Usually, the barbed rope column we install is cement column, but the use of cement column also has its drawbacks. For example, it’s not so convenient if we install it on a steep hill where transportation is not very convenient. This time can use barbed rope with the composite column to install.
