Post time: 15-03-23 - For single-layer wound non-rotating wire rope, it is necessary to strictly abide by the above principles, otherwise it is easy to cause permanent deformation of wire rope structure; In the case of multilayer winding, the rotation of the rope is determined by the orientation of the reel’s rope groove to lay the foundation for the next layer. The friction between the wire rope and the extrusion pressure of the multi-layer winding drum are large, and the disorderly rope phenomenon is easy to occur. Therefore, the wire rope with a diameter slightly smaller than the pitch of the rope groove and the diameter of the rope groove should be selected to add the touch area between the wire rope and the drum.

The advantage of galvanized iron wire after annealing: after annealing increases the elongation of the iron wire. Makes the product softer and increases the range of application. After electric galvanizing hot dip galvanizing. Copper electroplating is widely used and screen production. Galvanized iron wire is a soft iron wire product processed by low carbon steel wire through cold drawing, heating, constant temperature, and even heat preservation. Generally, the quality of ordinary galvanized iron wire will be relatively soft, the softness is relatively balanced, and the color is consistent. It is mainly used in construction, mining, chemical industry and so on.

1. The waterproof layer at the bottom of the cage should be checked regularly to prevent leakage at the bottom and replaced in time to avoid dropping liquid objects such as bird droppings, urine and water, resulting in corrosion of the cage edge.
- Reverse twisting of the barbed rope: first wrap the barbed wire around the main wire (that is, a single piece of iron wire) and then add an iron wire and twist together to form a double strand of barbed rope.
- Steel wire mesh is finished by fine welding of active welding equipment. The material can be divided into cold wire drawing, hot galvanizing, cold galvanizing, dip plastic and so on. To be used for bridge reinforcement, bridge deck pavement, building reinforcement and so on.

Paint on the galvanized layer, the binding force between each other and the baking temperature of the paint has a great relationship, after galvanized coating alkyd paint, adhesion is no problem. Galvanized amino paint, paint adhesion is not good. Do two bottom two surface, adhesion is ok, if the two bottom two surface to two bottom three surface, that is, more paint, more baking once, again test adhesion is very poor, poor to the paint from the galvanized layer of pieces torn off.
- 2. When there are channels, ponds, lakes and other natural barriers on the side of the road, there is no need to worry about people and animals entering and illegally occupying the road land.

If not packaged, then a car of blade thorn rope can not be loaded with many pieces, but also relatively occupied places and easy to be lost in the process of transportation. Each bundle of blade barbed rope is 50 bundles. After hydraulic compression, the volume is reduced and it is more convenient to load and unload. Forklift trucks can load and unload easily. In general, when exporting, the blade thorn rope will be packaged for sale, so that the volume occupied in the container is relatively small, which can be very easy to size and place will not take up much place.
- Generally speaking, in dry main gas and indoor use, the thickness of galvanized coating is only 6-12μm, but under poor environmental conditions, the thickness of galvanized coating is 20μm, can reach 50μm. Therefore, environmental factors should be considered when choosing the thickness of galvanized layer. Galvanized layer after passivation treatment, can naturally form a layer of bright, beautiful color passivation film, can obviously improve its protective function, decorative.
- 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.

Post time: 08-10-22 - When pickling, the galvanized wire needs to be slowly put into the cylinder to avoid liquid splashing on the body. Protective glasses should be worn in the pickling process to prevent acid splash out and hurt people. Pay attention to safety when receiving the line operation, the line tray needs to be lightly placed, stacked neatly, not more than 5 disks. No matter what kind of auxiliary materials are used, galvanized wire drawing must comply with national regulations, otherwise it is not allowed to be used.

Barbed wire is used to make barbed wire, in part, to prevent 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, it is because livestock generally have the habit of charging, and the barbed rope is used to circle, which makes livestock dare not rush to charge the barbed rope, thus saving the user’s use cost.
- At present, the blade rope has been widely used in many countries of industrial and mining enterprises, garden apartments, border posts, military fields, prisons, detention houses, government buildings and other national security facilities.
- Galvanized wire is coated with a layer of stable zinc on the outside of the wire, and the zinc layer is used to protect the wire and make the service life of the wire longer. In the production of galvanized wire, the wire should be pickled. Pickling is to use some acid mist or acid liquid to wash away some oxides on the surface of iron, that is, rust, and some other corrosion, to achieve the purpose of cleaning iron, so that zinc will fall off when galvanized.
- Filament is not thought to last as long as thickness, and common sense agrees. But the positive and negative twisting of barbed wire is hot galvanized steel wire, which is more than 3 times larger than the tensile strength of iron wire, and the zinc content is not less than hot galvanized wire.
-
Large rolls of galvanized wire in oxygen violently extinguished, spark, and sodium block, magnesium strip in oxygen extinguished, no spark phenomenon. This phenomenon is determined by the composition of galvanized wire. The galvanized wire used in the experiment is pig iron or steel wire, pig iron and steel are iron and carbon alloy, containing iron and carbon two elements of complex material. Carbon in galvanized wire will produce carbon dioxide when extinguished, solid into gas, volume will shrink rapidly.
- Relatively speaking, the wire is relatively soft, suitable for binding. Disadvantages are low hardness, low tension, easy to stretch, not suitable for building materials. In different applicable environment, we should make a reasonable choice. So in the usual use of cold drawing wire and wire, according to their own needs to choose, although the length of the same, but the performance is not the same.
-
The use of packaging galvanized wire with the development of industry and agriculture is also expanded accordingly. Therefore, galvanized silk commodities have been widely used in industry (such as chemical equipment, petroleum processing, Marine exploration, metal structure, electric power transportation, shipbuilding, etc.), agriculture (such as irrigation, heating houses), construction (such as water and gas transportation, wire casing, scaffolding, houses, etc.), Bridges, transportation, etc., in recent years. Because galvanized silk products have beautiful surface, good corrosion resistance and other characteristics, its use is more and more extensive.
-
Compared with other galvanizing processes, the cleaning requirements for low carbon steel wire before galvanizing are low. 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 the production, it is very important to properly clean and effectively rinse the substrate before electroplating.
- Because the large roll galvanized wire alloy element in ore iron, can make copper through the thickness, hardness, impact force, strength, library rate, elongation, so alloy iron in the exercise of good iron, is an important auxiliary element. Galvanized wire and general wire is very different, general wire is cheap, and because the iron is not very stable, easy to rust in the wet place, so the stability is not very good, the life is not very long.
-
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.
