- The quantity should be the same as the contract, cold drawing, carefully record the quantity of each specification and packing method. If there is a label, check whether the label is correct and take a photo to confirm. Each roll of iron wire is fastened with galvanized packing tape, and then tightly bound with a very strong transparent plastic bag. The outer layer of coated iron wire is wrapped with white braided cloth, and the outer layer of galvanized iron wire is wrapped with green braided cloth, so as to ensure that the packaging will not be lax in the transportation process. One end of the wire must be clearly marked and the other end left on the outer layer for easy connection by other wires.
Factors affecting the corrosion resistance of galvanized wire: The corrosion resistance of galvanized wire is affected by many factors, mainly including the following aspects.
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.
Moderate rates of foam formation may be harmless. The presence of small, homogeneous particles of large denier in the tank can stabilize the foam layer, but the accumulation of excessive solid particles can cause an explosion. Using activated carbon mat to remove surface active substances, or through filtration to make the foam is not too stable, this is an effective measure; Other measures should also be taken to reduce the amount of surfactant introduced to Z.
(1) In the painting construction should pay attention to ventilation, moisture-proof, fire prevention. The working environment and painting tools should be kept clean, the pressure of the air pump should be controlled within 0.63MPa, and the safety valve should be checked for failure.
The galvanized layer forms a particular metallurgical structure that is capable of accepting mechanical damage during transport and use. Every part of the plating can be zinc plated, even in dents, sharp corners and hidden places can be fully maintained. The galvanizing process is more convenient than other coating construction methods, and can avoid the required time after the installation on the site.
- In addition to these reasons, we should also pay attention to the tooling and process must be stable, and regular testing should be done to ensure the uniformity of galvanized layer.
The hot dip galvanized hexagonal net is made of low carbon steel wire by mechanized braided welding and then by hot dip zinc treatment. Net color bright white, thick zinc layer, uniform mesh, mesh surface smooth, solder joint tensile resistance, high corrosion resistance.
This oxide film has greater elasticity and lubricity, does not affect the accuracy of parts. Therefore, the parts of precision instruments and optical instruments, spring steel, thin steel sheet, fine steel wire and so on are commonly bluing treatment. The commonly used galvanizing treatment of large roll galvanized wire is equivalent to forming a protective layer on the surface of the iron wire. The commonly used methods are hot dip galvanizing, hot spray plating, vacuum plating and so on. Different methods have corresponding characteristics.
Blade barbed rope is a new product of safety protection supplies, and other barbed rope is different with very sharp blade, its production process is the stainless steel sheet stamping forming. The blade barbed wire protective net is a new kind of protective net. The blade barbed wire produced by our factory is made of corrosion-resistant hot-dip galvanized steel plate or stainless steel plate.

In order to pack and bind galvanized wire in the surface of the sedimentary layer to local removal of surface film, surface inclusion and other defects can be found and treated by conventional technology; Excess foam is formed when soap and surfactants such as saponified fats are brought into the tank. Moderate rates of foam formation may be harmless. Small, homogeneous particles of large denier present in the bath can stabilize the foam layer. Use activated carbon mat to remove surface active substance. Or through filtration to make the foam is not too stable, which are effective measures; Other measures should also be taken to reduce the amount of surfactant introduced. The electroplating speed can be obviously reduced by the addition of organic matter. Although chemical formulations facilitate high deposition rates, the deposition of organic matter does not meet the requirements of coating thickness, so activated carbon can be used to treat the bath.
- But there are some necessary precautions in the production of galvanized wire. Remove all tools and piles on the work site and equipment that hinder activities, and slowly put the wire into the cylinder during pickling to prevent acid splashing on the body. When adding acid, the acid must be slowly poured into the water. Do not pour water into the acid to prevent acid spillage and injury. Workers should wear protective glasses when working. Then in the handling of wire and other items, it is strictly prohibited to push hard.
- Barbed wire, on the one hand, is a great protection against livestock theft, because the surface is covered with sharp spikes that make it very difficult to penetrate through the barbed wire. On the other hand, because livestock generally have the habit of bumping, the barbed rope is used to circle, which makes the livestock dare not rush to collide with the barbed rope, so as to save the use cost of users.
Cold galvanizing, also called electric galvanizing, is the use of electrolytic equipment to remove oil, pickling, after the pipe fitting into the composition of zinc salt solution, and connected to the negative electrode of the electrolytic equipment. Wire factory on the opposite side of the pipe fittings placed zinc plate, connected to the positive electrode of the electrolytic equipment is connected to the power supply, the use of current from the positive electrode to the negative electrode will deposit a layer of zinc on the pipe fittings, cold plating pipe fittings is first processed after galvanized.
Hexagonal mesh is a metal wire woven Angle mesh (hexagonal) made of wire mesh, the use of metal wire diameter is based on the size of the hexagonal and different. Also known as: twist flower net, stone cage net, gabion net, flood control network.
After the optimization of the process, mass production of 0.80mm electro galvanized steel wire electro galvanized zinc layer quality is controlled within 80 ~ 90g/m2, zinc layer quality dispersion is very small; The results show that the average weight of zinc layer is 14.5g/m2, the loss of zinc layer is less than 5%, and the tensile strength of steel wire is 2300 ~ 2500MPa. It not only effectively controls the quality of zinc layer of raw steel wire, but also reduces unnecessary waste and production cost.
The characteristics of hexagonal net: solid structure, flat surface, with good corrosion resistance, oxidation resistance and other characteristics: used for raising chickens, ducks, geese, rabbits and zoo fences, mechanical equipment protection, highway guardrail, sports places Seine, road green belt protection net. The screen in the production of box shaped container, with stone filled with cages, can be used to protect and support seawall, hillside, road and bridge, reservoir and other civil engineering, is a good material for flood control and flood resistance, namely (stone cage net, stone cage cage).
- In general, the organic matter contained in the galvanized wire can make the plating speed significantly reduced. Although the chemical formulation is conducive to high deposition rate, but the organic matter with the coating thickness can not meet the requirements, so activated carbon can be used to treat the tank liquid. Zinc is a silver-white metal, brittle at room temperature, soluble in acid can also be soluble in alkali, known as amphoteric metal.
- Some welding methods of galvanized steel mesh will reduce the quality of low carbon steel welded joints, such as electroslag welding. Because the line energy is high, the coarse grains in the heat affected zone of welding will become very coarse, leading to a severe reduction in impact toughness. After welding, it is necessary to normalize with refined grains to improve impact toughness.
