2. Visual Wear Cracks, fraying, or shiny spots on the belt’s surface are clear indicators that it may need to be replaced.
If the blade barbed rope produced by the barbed rope factory wants to be made into a straight line, it can’t be made too long because of the constraints of logistics.
Post time: 13-07-22Many customers are in great need of galvanized barbed rope when they decide to purchase it, and the barbed rope specification determines the length of the later installation.
- Different hot dip galvanizing process is divided into two categories of annealing outside the line and annealing in the line, hot dip galvanizing is in the hot melt zinc liquid immersion plating, production speed, thick but uneven coating, the market allows Z low thickness of 45 microns, Z high can reach more than 300 microns. It is dark in color, consumes more zinc metal, forms infiltration layer with base metal, and has good corrosion resistance. Hot dip galvanizing can be maintained for decades in outdoor environment.
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.
Therefore, the rust of galvanized black iron wire has a great relationship with storage. At the same time, after rust, it is also necessary to conduct reasonable post-processing to avoid affecting its use effect. Of course, when the black iron wire is galvanized, it is also necessary to ensure the thickness of the galvanized layer, so that it can also reduce the possibility of rust. Speaking of galvanized iron wire, perhaps many people think it is relatively rare, in fact, it is not.
Post time: 07-03-23The application of black iron wire in the process is mainly through the hot metal billet rolled into 6.5 mm wire rod, and then put it into the wire drawing device into a different diameter line, and then gradually reduce the aperture of the wire drawing disk, cooling and annealing, coating and other processes, made into a variety of different specifications of iron wire, this kind of iron wire and ordinary black iron wire compared, will be softer, Softness is also very uniform, color is consistent, widely used in the construction industry, mining, chemical industry, welding mesh, welding hanger, reprocessing industry.
- 4, barbed rope fence and culvert intersection, such as the ditch is narrow, barbed rope barbed rope fence can be directly across the ditch is wider, barbed rope barbed rope fence is difficult to cross, can take bridge, channel processing method.
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.
Galvanized wire to galvanized uniform, a body is now its cross section, the second is the longitudinal uniformity. In the actual operation process, such as the jitter of steel wire, the surface of the pot scum and other reasons will cause galvanized wire surface galvanized layer accumulation, should try to solve the problem.
- Especially after passivation of galvanized layer, the surface of the oxide layer is thicker and compact, itself has high oxidation resistance. On the other hand, when the surface of the galvanized layer is damaged, exposing the inner iron matrix, because zinc is more active than iron, zinc will bear the role of sacrificing zinc anode, zinc will be oxidized before iron, so as to protect the iron layer will not be damaged.
- The bird cage is the main environment for the birds to live and live in. Only with proper cage and other accessories, can the birds be kept healthy and lively, singing freely and suitable for viewing.
The 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.
Product features: strong structure, flat surface, with good corrosion resistance, oxidation resistance. The material of small hexagonal mesh is the same as that of other hexagonal mesh, which is generally made of low carbon steel wire, stainless steel wire and galvanized steel wire as raw materials by the hexagonal mesh machine.
Galvanized wire mesh is divided into hot dip galvanized wire mesh and cold galvanized wire mesh. Galvanized steel wire net selects the high quality low carbon steel wire, iron wire factory made by precision of automation machinery welding technology processing, smooth surface, firm structure, integrity is strong, even if the local cutting of galvanized steel wire net, or local also under pressure from loose phenomenon, after molding, wire mesh galvanized corrosion resistance good, has the advantage that the general steel mesh does not have.
- 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.
Zinc is a silver-white metal, brittle at room temperature, soluble in acid can also be soluble in alkali, known as amphoteric metal. Pure zinc in dry air is more stable, in humid air or containing carbon dioxide and oxygen water is small, the surface will generate a layer of basic zinc carbonate based thin film layer, it can delay the corrosion rate of zinc layer. The corrosion resistance of zinc coating in aqueous solution of acid, alkali and sodium chloride is stronger.
Post time: 04-11-22Take 20cm galvanized wire for acid fog experiment, check the zinc content of galvanized wire through the balance to see whether it meets the zinc layer standard required by customers, ensure that the metal wire achieves the role of rust and corrosion prevention, and meet the service life required by customers. Galvanized iron wires must be packed in good condition, bound neatly and orderly, and bound inward to prevent scratches during transportation. The inspection standard of galvanized iron wire also includes the tensile test, which is decided according to the material of the galvanized wire order ordered by the customer, and it needs to be tested by comparing the raw material list.
- The main raw materials of blade barbed wire are galvanized wire and galvanized sheet. Because the price of galvanized sheet is more expensive than galvanized wire, it is directly reflected in the price of blade barbed wire sales. There is also the difference in processing technology also leads to the difference in the price of the blade barbed rope. The traditional barbed rope is mechanically twisted, with relatively small labor consumption and high production efficiency. But the blade barbed rope is after the second mechanical processing in the artificial processing operations to appear. Therefore, there is a big gap between labor force and production efficiency. These factors lead to the price of the blade barbed rope is more expensive main factors.
- General material: electroplated low carbon steel wire
If the zinc coating is good, but when the light comes out in 3% nitric acid, there is a dark shadow on the coating, and the film is brown when passivation occurs, which may be caused by foreign metal impurities such as copper or lead in the galvanized liquid. When there is a problem in the process of galvanizing, check the temperature and current density first, and then measure and adjust the content of zinc and sodium hydroxide in the bath through the analysis of the bath. Whether DPE levels are low can be determined by Hull cell test.

Products are widely used in construction, handicrafts, wire mesh, highway guardrail, product packaging and daily civilian and other fields. Galvanized wire is divided into hot galvanizing, cold galvanizing, electric galvanizing, hot galvanizing price is high, the price of electric galvanizing is low. Hot dip galvanizing is not easy to rust, electric galvanizing is easy to rust, this is a simple discrimination. Hot dip galvanizing is dipped in zinc liquid melted by heating, with fast production speed and thick but uneven coating. The market allows a low thickness of 45 microns and a high of more than 300 microns.
Galvanized hexagonal mesh uses: building wall fixed, heat preservation, heat insulation; Power plant piping, boiler heating; Anti-freezing, residential protection, landscaping protection; Raise chicken and duck, isolate chicken and duck house, play the role of protecting poultry; Protect and support seawalls, hillsides, roads and Bridges and other waterworks.
The use of galvanized anticorrosion treatment is better, the metallurgical connection between galvanized layer and steel, combined with the appearance of steel as a whole, making the coating more durable, more reliable. In the suburbs, the galvanized thickness of hot dip galvanized can adhere to more than 50 years without repair, in the suburbs or near the seaside, galvanized layer can adhere to more than 20 years without repair, is the choice of anti-rust and anti-corrosion. Coating has strong toughness, in the process of transportation or use, can resist extrusion, withstand some damage, hot dip galvanized anticorrosion treatment both save time and effort, and faster than other processing, than dipping, spraying to save much time and effort.
3. Put zinc block into the plating aid pool regularly, so that the bivalent iron in the plating aid becomes trivalent iron, and it is an important measure to stabilize the PH value in a numerical range. At the same time, it is convenient for the filter 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.
