Galvanized wire is divided into hot galvanized wire and cold galvanized wire (electric galvanized wire). Hot dip galvanizing is dipped in zinc liquid melted by heating. It has fast production speed, thick but uneven coating. The market thickness is 45g and can reach more than 300g. The color is dark, the zinc metal is consumed, and the matrix metal is formed into the entry layer, the corrosion resistance is good, and the outdoor environment of hot dip galvanized can adhere to decades.

In strict accordance with the multi-pass small compression rate drawing, the total compression rate is 96.48%, reducing the scraping of zinc layer. The whole wire drawing die is made of tungsten steel die and polycrystalline die. The Angle of the working cone of the wire drawing die is 12° ~ 16°, and the length of the sizing belt is 0.15 of the diameter of the wire, so as to ensure that the deformation of the zinc layer is basically synchronous with the steel wire substrate.

If it is not packaged, then a car of blade thorn rope can not be loaded with many pieces, and it is also relatively occupied and easy to lose in the transportation process. The number of the packed blade thorn rope is 50 bundles, and the volume is reduced after hydraulic compression so that it is more convenient to load and unload, and the forklift can easily load and unload. Under normal circumstances, when exporting, the blade thorn rope will be packaged and sold, so that the volume occupied in the container is relatively small, which can be easily placed and will not occupy much place.

The application of electric welding mesh is more widely, at present, it has replaced the use of other parts of the screen, the cost of electric welding mesh is low, the production speed is very fast, so it is very popular. The treatment required before galvanized welding mesh is recrystallization annealing, because the welding mesh must maintain an oxide and no other impurities of pure iron active surface, if you can’t keep its surface clean will lead to poor galvanized effect, galvanized layer and iron material is not tightly combined, so this step is necessary.

The temperature of large roll galvanized wire should be controlled at 30 to 50℃ during electroplating. Because the chloride ions in the bath are very corrosive, quartz glass heaters are generally used. 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.

After electric galvanizing hot galvanizing. Electroplated copper and other common applications of screen consumption. The weaving of the binding of the building steel wire mesh has the first braided after plating, plating after weaving and other methods, after the disposal of the wire mesh or wire mesh has good corrosion, oxidation resistance characteristics, can be used in the construction, petroleum, chemical, aquaculture, garden protection, food processing and other industries of reinforcement, protection and insulation.

After proper heat treatment or cold drawing hardening, high carbon steel wire has high strength and hardness, high elastic limit and fatigue limit (especially notched fatigue limit), cutting function is acceptable, but welding function and cold plastic deformation ability is poor.

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.

No matter how good the quality of hot-dip galvanized barbed rope is, it is only attached to the surface of the wire with galvanized layer, and with the cause of chemical reaction, the zinc layer on the surface will gradually lose its effect because of oxidation reaction, which is more prominent in the humid area of the environment. And because, after all, the wire will rust, so the quality of hot-dip galvanized barbed rope is certainly not up to the level of stainless steel barbed rope.

Bridge protection system generally do not need to be specially installed special drainage system, the use of hexagonal mesh made of gabion mesh box, the inside of the filler are selected stones, these stones are not easy to wear, and between the stones and stones will retain some gaps, so it is very good to meet the drainage requirements.
