Large coils of galvanized wire are divided into hot dip galvanized and cold dip galvanized. Hot dip galvanized wire is dark in color, consumes more zinc metal, forms infiltration layer with the base metal, and has good corrosion resistance. Hot dip galvanized wire can be maintained for decades in outdoor environment. Cold galvanized production speed is slow, uniform coating, thin thickness, usually only 3-15 microns, bright appearance, poor corrosion resistance, generally a few months will rust.

2. The cleaning agent used for cleaning should have no effect on the binding force of the coating and no corrosion on the matrix.
Now it is more used in the binding of the construction industry. Compared with ordinary iron wire, it is softer and has better luster. Use in daily life does not need to carry out maintenance and maintenance, save a lot of time, but also save the cost of maintenance and maintenance. Annealed wire has good stability, good corrosion resistance, greatly prolonging the service life. More kinds, can be selected according to different uses, making annealing wire device is simple, improve the utilization rate of the device. The material properties of annealed wire can meet different processing requirements.
The blade gill net of plastic paint is formed after rust protection processing after the manufacture of blade type barbed iron wire rope. The periphery of blade gill net should have good rust prevention effect, the peripheral processing should be beautiful, and can be of good practical value, more convenient installation, higher cost performance and other advantages. Plastic paint is a common electrostatic coating method, which can be fixed on the periphery of chicken wire or wire plate. After two hundred heat treatment, plastic paint or powder paint is glued to the surface of wire plate. These blade gill nets coated with plastic paint are generally used on indoor boxes. The coating processing does not take too long, mainly because the effect of rust prevention and corrosion protection is quite good, much better than the general material.
2, performance characteristics. Zinc coating is thick, fine crystallization, uniform and no pores, good corrosion resistance; Is pure, the zinc plating layer in acid, alkali corrosion slower, such as fog Eng effectively protect tight sand-fixation matrix, the galvanized layer formed after chromate passivation, color white, army green, beautiful and easy, have certain adornment sex, because the galvanized layer has good ductility, and therefore can be rushed, rolling, cold bending and forming and not damage the coating.
- Hot dip galvanized steel wire surface smooth, smooth, no cracks, joints, thorns, scars and corrosion, galvanized layer uniform, strong adhesion, corrosion resistance lasting, toughness and elasticity is excellent. The tensile strength should be between 900Mpa-2200Mpa (wire diameter Φ0.2mm-Φ4.4mm). The number of torsion (Φ0.5mm) in more than 20 times, repeated bending should be more than 13 times. The thickness of galvanizing is thin, usually only 3-15 microns, bright, smooth, beautiful appearance, poor corrosion resistance, generally a few months will rust.
Post time: 31-01-23Customers in the order of wire mesh will often shop around, most customers are in comparison with manufacturers to give the product price, the company tells you, do not blindly compare the price. To standards, production technology, manufacturers and other factors lead to different prices.
If not packaged, then a car of blade thorn rope can not be loaded with many pieces, but also relatively occupied places and easy to be lost in the process of transportation. Each bundle of blade barbed rope is 50 bundles. After hydraulic compression, the volume is reduced and it is more convenient to load and unload. Forklift trucks can load and unload easily. In general, when exporting, the blade thorn rope will be packaged for sale, so that the volume occupied in the container is relatively small, which can be very easy to size and place will not take up much place.
- Galvanized wire for welding is generally required to have a certain hardness, after acceptance of galvanized wire, feel is the first thing to do, in addition to the machine test, because the average user does not have testing equipment, on the machine trial is also a very inconvenient way to test. The diameter of electric galvanized wire is measured with a micrometer, and it is kept at about 0.02mm above and below the contract signing standard, with neat appearance, no leakage plating and no messy wire.

The dog cage is equipped with a fixed food basin and a drinking device, and the rubber pad of the pet cage with a bayonet on the four sides can be assembled. Can be splicing according to the size of the cage, shear, disassembly convenient, easy to clean, can solve the puppy in the ordinary cage pinched foot problem, prevent the puppy in the development of adverse reactions. The bulkhead of the pet cage is breathable and comfortable, which can be used as a heat shield for pets in summer. A puppy with small feet, not a foot, not a pinch.
Post time: 10-11-22- Galvanized iron wire is divided into hot galvanized wire and cold galvanized wire (electric galvanized wire) is made of low carbon steel, after drawing molding, pickling rust removal, high temperature annealing, hot galvanized, cooling and other processes. Galvanized iron wire has good toughness and elasticity, zinc content can reach 300 grams/square meter. It has the characteristics of thick galvanized layer and strong corrosion resistance. The products are widely used in construction, handicrafts, wire mesh, galvanized hook mesh, spackle mesh, highway fence, product packaging and daily civilian and other fields.
- ③ The galvanized iron wire shall not be damaged when it is tightened.
- For example, if the barbed rope is used for circling, the cost per meter is only a few yuan. If the other products are used for circling, it may be more than ten or even 20 yuan. This is undoubtedly to increase the cost of users again, so the barbed rope is the most economical and affordable product for breeding cattle and sheep.
Post time: 10-02-23Out-of-line annealing means that the recrystallization annealing of hot or cold rolled steel plate is carried out in the bottom type annealing furnace or cover type annealing furnace before entering the hot plating wire line, so that there is no annealing process in the galvanized line. The steel plate must maintain a clean active surface of pure iron, free of oxides and other dirt, before hot dip galvanizing. In this method, the annealed surface oxide sheet is first removed by pickling method, and then coated with a layer of zinc chloride or a mixture of ammonium chloride and zinc chloride solvent for protection, so as to prevent the plate from being oxidized again.
- Technical product wire, choose a wire special processing, no broken end, zinc amount uniform bright, general quotation slightly expensive. Galvanized silk also contains sprinkling: one plate per volume weight of about 100kg-1000 kg, mainly suitable for industry, agriculture, animal husbandry. Strong corrosion ability, solid coating and other characteristics.
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.
