The formation process of hot dip galvanized layer is the process of forming iron-zinc alloy between the iron matrix and the outside pure zinc layer. The surface of the workpiece forms the iron-zinc alloy layer during the hot dip plating, 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 solution, 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 gravitational attraction between the atoms is relatively small.

- If adult dogs touch noses with puppies out of affection, adult dogs touch noses with dogs that have more meaning in life. For example, dogs can touch their noses to communicate where food is safe and whether people or other animals are in danger.
The entire steel surface is protected, and the melted zinc is easily coated evenly, whether in the interior of the pipe fitting in a depression, or in any other corner where the coating is difficult to access. The hardness of galvanized coating is greater than that of steel. The Eta layer of the upper layer of Z is only 70 DPN hardness, so it is easy to be dented by collisions. However, the hardness values of the lower layer of Zeta layer and delta layer are 179 and 211 DPN respectively, which are higher than that of the iron material of 159 DPN. Therefore, its impact resistance and wear resistance are quite good.
In our daily life, what we can bend with our hands is basically galvanized iron wire, not steel wire. It has a high zinc content, which ensures excellent toughness and resilience, as well as ultra-high corrosion resistance, which can be maintained in outdoor environments for decades. There are many practical galvanized iron wire, such as strong reliability, galvanized layer and iron together, forming a special metallurgical structure, in the use and transportation process, can ensure that it will not be mechanical damage.
Post time: 04-08-22In the process of composite electroplating galvanized wire, the plating solution must be stirred to obtain the composite coating in which the particles dispersed in the matrix metal. Stirring methods include mechanical stirring, air stirring, ultrasonic stirring, bath circulation, etc. The acid activation solution in the production process can remove the corrosion products and oxide film on the surface of the low carbon steel wire without excessive corrosion on the matrix.
2. Use a large pickpocket to stir the zinc ash before the steel wire enters the zinc liquid; Use a small outlet for the galvanized steel wire; Zinc pot steel wire outlet in 30 minutes, with pickpockets back and forth, until the large, floating zinc residue into brown, real zinc ash, zinc ash surface. After the removal of zinc ash should be brown yellow real zinc ash, zinc surface, effectively reduce zinc consumption. This is one of the measures to reduce zinc consumption, but it is also a real problem, which has not been solved for many years.

Post time: 30-05-22- The advantages of hook net hook net raw material resolution of its use, used for road guardrail, sports stadium fence, etc., because the weaving characteristics of hook net can make the guardrail both beautiful and useful, have a good ability to hit, and can extend the service life, not easy to fade to prevent the effect of beautiful. And can also be used for family interior decoration, because its plasticity is very good so the use is also very much, is now many local are widely used.
- There is also a kind of stainless steel welding railing, which is also called: bridge anti-throwing mesh guardrail, in fact, the meaning of the river isolation net is the same. Stainless steel railing is a kind of high performance guardrail which has higher hardness, and corrosion resistance use long life. There are many varieties of it and also different shapes. Its basic function is to connect the guardrail structure. General guardrail thickness should be maintained at 0.7mm and above, the guardrail installation is more complex. If the tube part has some thin, affect the service life of the guardrail.
Post time: 10-06-22- In the processing of stainless steel barbed wire after cold galvanized or hot galvanized coating on the surface of the last zinc material, not only beautiful but also plays a good protective role.
- 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.
For mountainous or hilly areas where the ground is more undulating set up stakes. You need to set a stake at the beginning and the end, and then determine the position. In the middle of the ups and downs, to increase the stakes according to the complexity of the ups and downs of the terrain, we need to be able to see 3 stakes at the same time, so that the installation is. It’s a straight line.
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.
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.
- 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.
- Avoid hanging cages near heaters, as failure to dissipate heat can interfere with bird molting.

Post time: 31-10-22- The tensile resistance of welding net to 120N, otherwise for unqualified welding net. In this respect, there is no simple way to test the tensile resistance of the welding net, only through professional tools, expert testing to test, we will not introduce in detail. The outcrop on both sides of the welding net should not exceed 2MM. The welding net diameter wire and weft wire crossing place should be welded firmly, but the edge of the welding net to weld firmly weft wire must come out some, to weld firmly, but can not come out too much, generally not more than 2 mm is qualified welding net.
