- National standards on the use of wire mesh standards have certain requirements, diameter and mesh size matching use, rather than simply diameter size, on the plaster layer to use is mesh should not be greater than 20×20, diameter is not easy to be less than 1mm, light selection diameter is not much significance, choose 40×40×0.9 and choose 10×10×0.6 wire mesh, Which one is better? 10×10×0.6, I’m afraid.
- ③ Galvanized iron wire shall not be damaged when it is tightened.
Post time: 17-04-23Guardrail in the purchase of how to install the correct is very important, and the installation of guardrail is important, the requirements of height and material are very strict.
- General material: electroplated low carbon steel wire
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.
Post time: 08-06-22- Galvanized iron wire is divided into hot galvanized wire and cold galvanized wire, the use of low carbon steel wire processing, after drawing molding, pickling rust removal, high temperature annealing, hot galvanized, cooling and other processes. Good toughness and elasticity, zinc content 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 the tie wire used in the building, the length of 20cm 30cm 40cm, can be cut off according to requirements.
Post time: 11-11-22- At present, it is recognized that the best surface treatment method for rust prevention is to make dacron rust. Generally, auto parts have been used this method for rust prevention. The salt water test generally lasts more than 96 hours. But if the hardware is used in very poor conditions, there are also people who use “asphalt” which is tar to do the surface treatment.
- (2) Greenhouse special electric galvanized shaft wire shall not be used for waist hoop compression reinforcement, usually not used for all binding.
What’s the difference between cold galvanized wire and hot galvanized wire? It is mainly different production process. Cold galvanized iron wire, also known as electric galvanized iron wire, is the use of electrolytic galvanizing process, and hot galvanized iron wire is the use of hot penetration galvanizing process. Compared with the two, hot dip galvanized iron wire thick coating, high zinc content, has stronger anti-corrosion and anti-rust effect. Similarly, the price is also higher, cold galvanized iron wire and hot galvanized iron wire which good? Mainly for the use of scenarios and requirements to choose appropriate galvanized iron wire, appropriate is better.
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. Electrode structure: portable non – electrode, including cylinder, tube, sleeve plug. The electrode is made of metal or metal oxide powder, such as high heat agent and additives. Paper tube is generally used for drug pipe, and metal tube can also be used for different welding parts and use environment. The plug is at the end of the electrode, which is the clamping part that matches the sleeve during welding and prevents the flux from leaking out of the tube.
1, stress relief before plating where the maximum tensile strength is greater than 1034Mpa key and important parts before plating should be at 200±10℃ stress relief for more than 1 hours, carburizing or surface quenching parts should be at 140±10℃ stress relief for more than 5 hours.
The distance between the adjacent two thorn rope installation do not know whether you have noticed? Careful observation can find that its spacing is not the same, the thorn rope factory for customer consultation when asking the installation height of the reason.
Post time: 22-05-23- After a long time of use, it will not rust after the corrosion protection layer on the surface of hot dip galvanized barbed rope, because the material inside the stainless steel barbed rope is the same as the material on the surface.
Post time: 17-06-22- The coating on the surface of the welding core is called the coating. The coating of electrode plays a very important role in the welding process. If the photoelectrode without drug skin is used for welding, in the welding process, oxygen and nitrogen in the air will invade a large number of molten metal, metal iron and beneficial elements such as carbon, silicon, manganese oxidation and nitriding to form various oxides and nitrides, and residual in the weld, resulting in slag inclusion or cracks in the weld. The gas in the weld pool may produce a large number of pores in the weld. These factors can greatly reduce the mechanical properties of the weld and make it brittle.
Post time: 13-05-22- Galvanizing refers to the surface treatment technology of plating a layer of zinc on the surface of metal, alloy or other materials to play the role of aesthetics and rust prevention. The main method used now is hot galvanizing. However, hot dip galvanizing industry has been developed with the rapid development of cold strip rolling in the past 30 years. The production process of hot-galvanized sheet mainly includes: raw plate preparation → pre-plating treatment → hot-dip plating → post-plating treatment → finished product inspection and so on.
Post time: 24-04-22- Good word of mouth blade barbed rope must be a reasonable evaluation given by consumers after using, this is because many people feel good after choosing the blade barbed rope, whether in terms of safety protection or in the overall decoration and beautification effect is very good, so that in the actual choice will be more assured, In the eyes of many people, the high quality razor cord will not have problems, or the overall service life is really long, so that we can reduce a lot of cost, and can know whether it is the best.
- Hot galvanized products in chemical equipment, petroleum processing, ocean exploration, metal structure, power transmission, shipbuilding and other industries have a wide range of applications, in the agricultural field such as pesticide irrigation, greenhouse and construction such as water and gas transmission, wire casing, scaffolding, bridge, highway guardrail and other aspects, in recent years has been widely used.
When galvanized wire out of the light plating should be carried out light treatment. The bath temperature of galvanized wire should be controlled well. Galvanized wire, also known as hot dip zinc and hot dip galvanized, is an effective way of metal corrosion prevention, mainly used in various industries of metal structure facilities. It is to immerse the steel parts after rust removal into the molten zinc liquid at about 500℃, so that the surface of the steel member is attached with zinc layer, so as to play the purpose of anticorrosion.
We compare the difference between galvanized welding net and other welding net by introducing in detail, and write the following to introduce its material: Galvanized welded wire mesh is made of low carbon wire, through automation of fine precision machinery equipment spot welding processing after forming, selection of disposal of the appearance of zinc leaching technology, produce practice British standard, with smooth surface neat, uniform layout to consolidate, the function is good, even if some sections or accept pressure also won’t attack lax appearances, it is the strongest anti-corrosion function in iron mesh, Screen mesh is iron use one of the most widely network class, excellent anticorrosive makes its popularity in the breeding, sucking the neat surface, increased the look and feel, can play will be decorating effect, this feature makes it reflected in the mining industry, because the select material of low carbon high quality material, make it unique iron mesh not usually have flexibility, Concluded that it is used in the process of plasticity, and then can be used for the deep processing of hardware technology, disorderly wall swing, underground leak-proof crack, light net body, make this cost is much lower than the cost of iron screen, more can understand its economy, benefits. Galvanized welding net can be used as poultry cage, egg basket, channel fence, drainage tank, porch fence, rat net, mechanical protective cover, livestock and plant fence, grid frame, etc. It is also widely used in industry, agriculture, construction, transportation, mining and other occupations.
In a rainy climate, it is good to find a place with high dry ground. If there is a rain cloth to hide the rain, so much the better. For field operators, please rest assured that the safety and stability of the mesh, especially in the stacking of paper, slight corrosion will not affect the application.
- For corn circles: used as corn circle nets, the original galvanized welded wire mesh with a mesh size of 5cm*7cm or 5cm*5cm is generally used, with a wire diameter ranging from 1.8mm-2.3mm and a height ranging from 1.2m to 1.8m.
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.
- 5, when limited by the terrain, the barbed rope barbed rope protective net before and after the continuous setting, take the place as the end of the barbed rope protective net, and deal with the end of the sealing.
Cold galvanizing (galvanizing) is in the plating tank after the current unidirectional, so that the zinc gradually plated on the metal surface, slow production speed, uniform coating, thin thickness, usually as long as 3-15g, bright appearance, poor corrosion resistance, usually a few months will rust. Compared with hot dip galvanizing, the production cost of electric galvanizing is lower.
The main difference between the two is the carbon content. The carbon content of iron is 2.11 percent or greater, while the carbon content of steel is 2.11 percent or less. The iron carbon alloy with carbon content above 2.11% is cast iron (pig iron), which is basically not malleable and cannot be drawn into wire. Secondly, the content of impurities is different. The content of harmful impurities such as sulfur and phosphorus in steel is smaller. Steel wire general color focus, iron wire color light point, white point.
