FGD technologies have been widely adopted in many countries as a means of meeting stringent environmental regulations and reducing the impact of air pollution on public health and the environment. In the United States, the Clean Air Act Amendments of 1990 mandated the installation of FGD systems on coal-fired power plants to reduce emissions of sulfur dioxide and other pollutants
Annealed wire is mainly made of soft iron wire through low carbon steel heating, hot drawing, constant temperature and other processes. Because of the differences in use, there are also different in the production process, and the specifications are varied. Annealed wire can be widely used, mainly because annealed wire and other kinds of wire, has many advantages.
- 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.
- After a long time of use, it will not rust after the corrosion layer on the surface of the hot-dip galvanized barbed wire has problems, because the material inside the stainless steel barbed wire is the same as the material on the surface.
When the zinc layer is seriously damaged and endangers the iron matrix, the zinc will produce electrochemical protection on the matrix, the standard potential of zinc is -0.76V and the standard potential of iron is -0.44V. When zinc and iron form microbatteries, the zinc will be dissolved as the anode, and the iron will be protected as the cathode. Obviously, the atmospheric corrosion resistance of hot dip galvanizing is better than that of electric galvanizing.
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.
Hook mesh we usually see everywhere, in fact, hook mesh is a kind of fence, like the highway, stadium fence, road fence, etc., have hook mesh. So what are the effects and advantages of the use of hook net?
Hexagonal twist flower network is divided into heavy hexagonal network and small hexagonal network two categories. Both are made of steel wire braided with various materials, the difference is that the former uses thicker steel wire, and the latter uses finer steel wire braided.
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.
- Take 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 the customer, ensure that the metal wire can achieve the role of rust and corrosion prevention, and meet the service life required by the customer. Galvanized iron wires must be packed in good condition, bound neatly and orderly, and bound with an inward end to prevent scratches during transportation. The inspection standard of galvanized iron wire also includes the tensile test. This item is determined 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.
Post time: 10-03-23- “Wet” hot dip galvanizing is also called “molten solvent method” hot dip galvanizing. Iron and steel workpiece through degreasing, pickling and cleaning, it is necessary to set in a special box above the surface of the molten zinc in the “molten solvent” (also called cosolvent), and then into the zinc liquid to galvanized. The molten solvent is usually a mixture of ammonium chloride and zinc chloride, but also other chlorine salts.
- Purpose of galvanized hexagonal net: building wall fixed, heat preservation, heat insulation; Power plant tied pipe, boiler warm; Anti-freezing, residential protection, landscaping protection; Raising chickens and ducks, isolating chicken and duck houses, to protect poultry; To protect and support seawalls, hillsides, roads and Bridges and other waterworks.

Continuous production does not need heating, but needs cooling. Cooling can be in the groove side row thin wall plastic pipe, through the flow of tap water cooling, can also be used as a titanium pipe temperature control device. In 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.
1. Grid structure is simple, beautiful and practical; 2. Easy to transport, installation is not limited by terrain relief; 3. Especially for mountain, slope, multi-curved area adaptability; 4. Medium low price, suitable for large area use. Main market: railway, highway closed net, yard fence, residential guardrail, all kinds of isolation net.
Post time: 04-01-23- Hexagonal net structure can be used for slope support, excavation, rock surface net mine support form, slope vegetation (green color), railway road isolation block, it can be made into a cage, cushion, used for rivers, flood DAMS and seawall erosion protection and reservoir, river closed cage. Driving and directing river, river flood disaster is a major erosion of water river damage, resulting in flooding, resulting in a great deal of loss and property subjected to the amount of water and soil dissipation. Because of this, in dealing with these problems, the application of a lifestyle grid structure becomes a solution plan that has the potential to protect the bank forever.

The best way to manage off-road safety is to carry out management and protection from the source, maximize the safety of people’s lives and property, and reduce the non-operational costs of railway enterprises, which is a key content of railway safety work in the new era. At this time, it is necessary to install protective nets on both sides of the railway, which is what we usually say, blade barbed rope protective nets, which can prevent accidents.
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.
The quality of hot-dip galvanized barbed wire is only in the surface of the wire attached to the galvanized layer, and with the reason of the chemical reaction, the surface of the zinc layer will gradually lose its role because of the oxidation reaction, this situation is more prominent in humid areas. And because after all, the steel wire will rust, so the quality of hot-dip galvanized barbed wire is certainly not up to the level of stainless steel barbed wire.
Hexagonal mesh is also known as twisting mesh, thermal insulation net, soft edge net. It is made of single – layer mesh. Its mesh, mesh wire, galvanized and PVC film properties and the same as the cage. This product can be different shapes and sizes of the block stone into the alloy net to form a flexible whole, can be lifted, car, shipping to the designated place, the alloy net connected to each other into a larger whole, construction throwing convenient, fast, good economic performance.
- Because the barbed rope is a strong use of regeneration value. Generally, the use of discarded guardrail networks for exercise, or steel production of new structural raw materials, do a good job of daily cleaning up and recovery can promote the value of the whole guardrail network faster. Again is to recover the use, the use of it in the appearance of the use of places that are not high, such as as other days purse Seine; Taking apart or discarding the raw materials that do not need to rust can carry out the whole regeneration.

The formation process of hot dip galvanized layer is between the iron matrix and the outside of the pure zinc layer, the formation of iron-zinc alloy process, the workpiece surface in hot dip plating when the formation of iron-zinc alloy layer, 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 liquid, 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 attraction between the atoms is relatively small.
Post time: 12-06-24The error of construction welding net diameter should be controlled at 0.02 mm. For example, we buy wire diameter of 89 wire welding net, with a micrometer to measure the diameter, the diameter of the allowable range is 87 -91 wire. In this range is qualified welding net. Because the accuracy has been compared, but no one can control it so well in the production process. The welding net can be accurate to 0.01 mm, so the error is allowed.
