- 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.
- Because the coating obtained is thicker, hot-dip galvanizing has very good protective function than electric galvanizing, so it is an important maintenance coating for iron and steel parts in strict working environment. Hot-dip galvanized products are widely used in chemical equipment, petroleum processing, Marine exploration, metal structure, electric power transportation, shipbuilding and other occupations. In the field of agriculture, such as pesticide irrigation, greenhouse and construction industry such as water and gas transportation, wire casing, scaffolding, Bridges, highway guardrail and other aspects, it has been widely used in these years.
Post time: 17-05-23According to the galvanized iron wire manufacturer, galvanized iron wire is the selection of excellent low carbon steel, through drawing forming, pickling rust removal, high temperature annealing, hot dip galvanized, cooling and other processes. Galvanized iron wire should pay attention to the following points in the use process:
Hot dip galvanizing has been used for more than 150 years, and its principle has not changed so far. The steel structure should be fully immersed in zinc at one time to achieve uniform galvanized film structure. If it is too long or too wide to be dipped twice, the zinc layer at the joint will appear rough, too thick and so on. In addition, if the single weight of steel structure is too heavy, it will make its operation difficult if it exceeds the load of galvanizing equipment. Therefore, the communication with the hot dip galvanizing factory in advance.
The material of steel structure will affect the organization and thickness of hot dip galvanized film. For example, high tension steel containing silicon, carbon content is high, easy to react with molten zinc quickly, the result of excessive growth of alloying, will cause a grayish black appearance, but does not affect its corrosion resistance. Or heat treated steel, if its tensile strength exceeds 90kg/mm2, after hot dip operation, easy to reduce its strength, etc.

- Stainless steel barbed rope is in the material aspect of protection so durability is also better, these two products are known for long service life, but is high in price.
Post time: 14-12-22The lighting surface of each type of shed is designed to be curved, improving the Angle of the light surface, because the lighting surface is curved, no dust accumulation, good light transmittance, high temperature in the shed, after measurement, the average temperature in the shed is 3℃ higher than the traditional bamboo pole cement column shed, the yield is increased by 15~20%, and the harvest date is advanced. The formula is scientific, the surface does not absorb moisture, do not return halogen through modification technology and scientific production process, solve the greenhouse frame rod is easy to absorb moisture return halogen, poor water resistance and easy to change the shortcomings, so that the greenhouse steel pipe in the high temperature and high humidity environment, few drops, frost phenomenon, and reduce pests and diseases.
High quality galvanized wire in general, the zinc layer attached to the surface of the wire is relatively thick, so when we buy galvanized wire, as long as we look at the thickness of the zinc layer machine, we can generally judge whether the quality of galvanized wire is high quality.
And high quality data and production cost and production conditions are bound, so some welding screen manufacturers did not meet the requirements of this aspect, natural in this case there is no way to improve product strength. In addition to data, and produce process, even if again good data, but the factory did not meet the requirements of production process in welding, also can form the product under the high pressure welding, so it is also a kind of strength on the decline, process conditions of different manufacturers also have very big difference, so it formed a shopping mall on the above products are differences of strength.
- Determine the size of the cage based on the actual size of the dog as an adult. In general, the cage should be three times the size of the dog’s body, with enough room for the dog to turn around and so on.
Hook net: hook net also known as diamond net, rhombus net, slope protection net. It is widely used in warehouse, east and west cold storage, protection reinforcement, park, zoo fence, Marine fishing gate and construction site fence, mechanical equipment protection, highway guardrail, sports place purse Seine, road green belt protection net.

Compared with other galvanizing processes, galvanized steel wire has low cleaning requirements before plating. However, under the current trend of increasing the quality level of galvanized layer, some pollutants brought into the plating tank are obviously harmful. Because cleaning galvanized coating wastes a lot of time and reduces production, it is very important to properly clean and effectively rinse the substrate before electroplating.
Hot plating wire can generate thicker coating, and there are both pure zinc layer and iron zinc alloy layer, so the corrosion resistance is better. The production power of hot dip galvanizing is particularly high, and the duration of the parts in the hot dip galvanizing tank usually does not exceed lmin. Compared with galvanizing, hot-dip galvanizing has lower production cost and less environmental impact than galvanizing. To plate, tape, wire, tube and other profiles plating, automation degree is higher.
- If adult dogs and puppies touch noses out of love, then adult dog nose touching is more meaningful. For example, dogs can touch their noses to communicate where food is safe and whether people or other animals are in danger.
Post time: 17-10-22- Using the patented technology of the invention, regularly put zinc block into the plating aid pool, so that the bivalent iron in the plating aid into trivalent iron, and play a stable PH value in a numerical range of an important measure, but also easy to filter out the trivalent iron ions in the plating aid; Ferric 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 play the role of plating aid filter.

With the development of mining industry, the classification of pig iron is already very broad in our country, which can satisfy the demand of mechanical industry. In general, the iron used to produce large rolls of galvanized wire can be divided into two classes. A metal exercised directly from the iron ore through the iron making stroke, the composition of the ore is iron oxide, silica and other miscellaneous stones. When this ore is specially refined into metal iron, carbon, silicon, manganese, and other elements are mixed into it. The material produced in this way is called ordinary pig iron, which is also the material for the first grade.
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.
- (4) Stop the use of more than two strands of galvanized iron wire around the operation method.
The second is according to the barbed wire material to determine the importance of the process, it is especially embodied in hot dip galvanized barbed wire, because of the different treatments of barbed wire in wire material and ductility have some discrepancy, if not pay attention to in the process it is easy to damage on the surface of zinc layer, directly affect the barbed wire rust resistance.
