Post time: 08-10-22- The diameter of the wire is generally 0.3mm – 3mm, after the wire is not very strong, need to annealing, annealing this step is very important, can ensure the production of galvanized welding net, with good elasticity and toughness. After welding, the welding mesh becomes black wire welding mesh and can not be put on the market, because its corrosion resistance is poor and the service life is short, so it needs to be galvanized or dipped plastic treatment.
Pay attention to safety in line collection and operation, others without the consent of the monitor, Ben have to get on the bus operation. The reels should be placed lightly, stacked firmly and neatly, not more than 5 reels. Direct contact with acid and alkali must be prohibited. When the acid fog exceeds the specified target of the state, measures should be taken to control it in time, otherwise production is not allowed.

2, galvanized wire mesh molding sheet storage ground should be flat, according to the symbolic requirements of the accumulation of regular, height should not exceed 2M, and away from heat sources, avoid exposure.
Post time: 07-06-24- 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.
- 3, the external environment, the climate is dry and ventilated environment is not easy to rust.
The price of galvanized iron wire is relatively low, but the corrosion resistance is excellent, so it is favored by many screen businesses. In the production process of galvanized iron wire, first of all, we should check the equipment to see if there are any problems, and then we should look at the galvanized process, whether there are factors that cause product discoloration. If these problems do not exist, or some of them occur on the same equipment, and some are normal, then we should consider the problem of raw materials at this time.
- In the rolling process, if the surface of the steel wire is rough, the relative friction coefficient of the steel wire and roll increases, the friction resistance increases, the steel wire elongation decreases, the width increases. In the production of weighted leather material is easy to wide, is because of its rough surface. On the contrary, the surface of the steel wire is smooth, because the friction resistance between the steel wire and the roll is small, it is easy to extend, and the width is small. Domestic steel wire in order to prevent rust, the surface coated with butter, such as butter removal is not clean, easy to slip when rolled flat, also affect its width.
- The reason why there are black spots in wire mesh welding is that the action of wire feeding should be timely filled in the melting time, and the development should be appropriate. There is no argon gas, long burning, large current, long distance, blunt tungsten needle and high molten pool temperature are the fundamental reasons for blackening. Continuous burning, is about active welding machine energy selection, machine welding will appear black spots.
And high quality data is constrained by production cost and production conditions, so some welding mesh manufacturers do not meet this requirement, natural in this case, there is no way to improve the strength of the product. In addition to the data, there is the production process, even if it is the best data, but the manufacturer does not meet the production process requirements in the welding, it will also form the product under high pressure welding, so this is also a decline in strength, the process conditions of different manufacturers are also very different, so it forms the market above the product has a difference in strength.
Field fence line net is a streamlined, streamlined, beautiful, tacky, fashionable European elegance; The diversity of color selection, a variety of standard color card colors to choose from, can meet different varieties, different, different needs. On-site fence line can be separated from a variety of methods, and according to the customer’s disagreement request.
Post time: 12-06-24No matter how big they are, dogs seem to love touching noses with people and other animals. In fact, nose touching is a form of social interaction for dogs, much like shaking hands and hugging humans. But dogs don’t rub their noses with every person or animal. They choose who to rub their noses with. If they don’t like you or don’t know you at all, they won’t touch your nose. However, adult dogs will touch the nose of almost every puppy. They will not only touch the puppy’s nose, but also smell the puppy.
The size of the dog cage is generally relatively small, suitable for indoor small dogs, dog cage is easy to carry, go out to compare the use, folding dog cage high strength steel wire and steel pipe material, the outer layer spray treatment. Strong texture, excellent rust resistance, the dog cage inside the tray, can be pulled out, convenient to clean the dog’s urine and feces, folding, dog cage is suitable for families and pet stores to raise more pet dogs.
- In fact, after the construction of the power grid does not need to be energized, the only security measures can play the equipment is these galvanized barbed rope, in the choice of time is certainly to choose some of their own needs, and the quality of the product of reliable materials.
- C, coating uniformity: galvanized layer is basically uniform with copper sulfate solution test etched five times without exposing iron.
- In addition, hot-dip galvanized wire also needs to pay attention to maintenance and maintenance during use. Although it has good corrosion resistance, the zinc-iron alloy protective layer of hot-dip galvanized wire will gradually wear out after a long time of use. Therefore, regular inspection and maintenance of the surface of hot-dip galvanized wire, such as recoating or anti-corrosion treatment, helps to extend its service life.
Hexagonal guardrail network custom corrosion lost the original characteristics, in the shape, color and mechanical properties will change, resulting in equipment damage, pipeline leakage, etc., specifically, it is easy to break, lose the original protection function.

The welding core is the metal core of the electrode. In order to ensure the quality of the weld, there are strict regulations on the content of various metal elements in the weld core. In particular, there are strict restrictions on harmful impurities (such as sulfur and phosphorus), and the quality of the weld core metal should be better than that of the base metal. Arc welding cannot be carried out on a smooth rod without a coating. This is because the arc stability is very poor, splashing is very large, and the weld is not well formed. After long-term practice, it is gradually found that the performance of the electrode is greatly improved by coating the welding core with some mineral raw materials (i.e. electrode coating). (1) Ensure stable arc combustion, so that the welding process is normal. (2) Using the gas produced after the drug skin reaction, protect the arc and the molten pool, prevent the harmful gases in the air (such as nitrogen, oxygen, etc.) from invading the molten pool, such as these gases will cause cracks and pores in the welding material, so that the welding can not achieve the ideal effect. (3) After the drug skin is melted, slag is formed, which covers the weld surface to protect the weld metal, make the weld metal slowly cool, help the gas escape, prevent the generation of pores, and improve the structure and performance of the weld. (4) After melting, various metallurgical reactions will be carried out, such as deoxygenation, sulfur removal, phosphorus removal, etc., so as to improve weld quality and reduce alloying element burning loss.
- Many luxury cat, dog, parrot, bird and flock cages use iron square pipes. Luxury cages use iron square tubes that are usually used as the frame of the cage body, and then touch welded wire on each face. The characteristics of the square tube cage are more beautiful shape design, cage body more solid, surface treatment methods.
When using these two products, it is obvious that there is a gap between them. By pulling or bending the wire, it is often difficult to restore the original, for example, if the same place is repeatedly bent, it will be found that it has broken, and the cold drawing wire will not. Cold drawing wire compared with iron wire, its hardness, tensile resistance, bending ability is greatly enhanced, suitable for building materials.
When we buy barbed rope, we need to know the kilogram weight of each bundle and the length to be used, so as to decide which product to buy. Or let it check directly into how much money a meter, is also a means to avoid being cheated. What you need to know when buying is the weight, and the length of the barbed rope can be customized from 50-250 meters. If the barbed rope is installed in a large area, it is recommended to use the barbed rope of 250 meters to reduce the use cost and logistics and transportation costs.
