  • Packing and binding galvanized wire is in the liquid state of zinc, after a messy physical and chemical effect, not only on the steel plated thick pure zinc layer, and also generate a zinc-iron alloy layer. This kind of plating method, not only has the corrosion characteristics of the electric galvanized wire, and because of a zinc alloy layer. It also has strong corrosion resistance that can not be compared with electric galvanizing. Therefore, this plating method is particularly suitable for a variety of strong acid, alkali fog and other strong corrosive environment.

  • The drawing process of the product drawing process has a great influence on the product function. Generally, a large total surface reduction rate of about 90% (see area reduction rate) and a small pass surface reduction rate (about less than 23%) are selected to ensure the endurance of the product. On the high strength spring steel wire, drawing should control the exit temperature of each passage of the steel wire is lower than 150℃, to avoid the steel wire due to strain aging and appear to change the crack, which is the formation of steel wire scrap the primary disadvantage.

  • One is to do a good job of galvanized wire packaging, avoid bumping, to ensure the integrity of the zinc layer;

  • 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.

  • And high quality data and production cost and production conditions are bound, so some welding screen manufacturers did not meet the requirements of this aspect, natural in this case there is no way to improve product strength. In addition to data, and produce process, even if again good data, but the factory did not meet the requirements of production process in welding, also can form the product under the high pressure welding, so it is also a kind of strength on the decline, process conditions of different manufacturers also have very big difference, so it formed a shopping mall on the above products are differences of strength.

  • After a long time of use, it will not rust like the corrosion layer on the surface of hot dip galvanized barbed rope, because the internal material of stainless steel barbed rope is the same as the material on the surface.

  • Of course, these are limited to the maintenance of the indoor balcony, so outdoor, some of this is less than maintenance, some maintenance will waste resources, because of the expected life, in order to ensure the safety of the role, timely update is good.

  • Titanium alloy with low carbon content is obtained because the carbon content remains the original concentration. The hardness of titanium alloy is mainly related to its carbon content. Therefore, after carburizing and subsequent heat treatment, the workpiece can obtain the performance of hard and tough inside. Galvanized wire varieties are mainly classified into three categories: electric galvanized wire, hot galvanized wire and galvanized wire. Among them, the classification of galvanized wire is divided into large roll galvanized wire, medium roll galvanized wire, small roll galvanized wire, galvanized shaft wire, truncated galvanized wire and other main production varieties.

  • 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.

  • 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.

  • Operating procedures: When using cold galvanized wire, all tools and stacked objects obstructing activities should be removed from the work site and equipment. When pickling, put the wire into the cylinder slowly to prevent acid splashing on the body. When adding acid, it is necessary to pour the acid into the water slowly. It is forbidden to pour the water into the acid to prevent the acid from splashing out. Wear protective glasses when working. Do not push or beat cold galvanized wire and other articles when handling them.

  • 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.

  • Hot dip galvanizing is in the hot melt zinc liquid dip plating, production speed, thick but uneven coating, the market allows the thickness of 45 microns, up to 300 microns above. 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 protection of zinc coating on iron matrix has two principles: on the one hand, although zinc is more active and easy to oxidize than iron, but its oxide film is not as loose and compact as iron oxide. The dense oxide layer formed on the surface inhibits the further oxidation of zinc in the interior.
  • Electric welding mesh can be made into the form of mesh, mesh surface can be used to dip plastic or spray plastic process, forming a layer of protective film on the surface of electric welding mesh, can effectively make the wire and the outside of the water or with corrosive substances isolation, can achieve the effect of increasing the use of time, can also make the mesh surface show different colors, so that the mesh to achieve beautiful effect. Impregnated mesh is usually used for outdoor, and column link, can play a protective anti-theft effect.

  • Blade rope in the world has been widely used in the military, prison, government agencies, banks; Living community wall, private residence, villa wall, doors and Windows, highway, railway guardrail and border line and other protection security.

  • 2, oil: it is recommended to use cloth (there is a kind of textile cloth for polishing glasses, do not knit, because the nap is easy to fall off), oil to the inside and outside of the cage. The amount of oil is not much, because the bamboo material is old, density and hardness are relatively high.

  • The common barbed rope produced by the manufacturer is the 14*14 type of barbed rope product. Since the warp wire used is the same as the wire diameter of the barbed rope, it is easier to calculate the length and weight. Usually each kilogram of barbed rope can reach about 10 meters of service length. The length of each kilogram of raw material is about 35 meters. Since 35 meters of raw material wire diameter can produce 10 lengths of barbed rope cost.

  • Stainless steel barbed rope is in the material aspect of protection so durability is also better, these two products are known for long service life, but is high in price.

  • Galvanized iron wire can be divided into hot-dip galvanized iron wire and cold galvanized iron wire according to different processing methods. Galvanized iron wire is more prominent in its corrosion resistance. Galvanized iron wire has good toughness and elasticity, the amount of zinc can reach 300 g/square meter, with thick galvanized layer, strong corrosion resistance and other characteristics. Galvanized iron wire products are widely used in construction, handicrafts, wire mesh preparation, the production of galvanized hook mesh, wall mesh, highway guardrail, product packaging and daily civilian and other fields.

  • Galvanized hook net standard is thorough, mesh planning: 3cm-20cm, wire planning: 1.2mm-4.5mm, galvanized hook net 6000 square meters, some standards have in stock. Benefits: The selection of low carbon steel wire, the surface of cold galvanized (electric galvanized) hot galvanizing anti-corrosion treatment, net wire strong, strong protection, anti-corrosion time is long.

  • The shape of the cage has round, square, octagonal, hexagonal and other shapes. Because the circular space uses a large area, it is more suitable for the activities of birds, and it is not easy to get hurt, so it is popular with everyone. A cage is dear to a man who loves birds, for it is inhabited by his master’s birds. If well maintained, it can be maintained for many years. Let’s look at how to maintain the cage.

  • 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.

  • Bird food, now raising birds can be fed with bird food on the market, which is more convenient, of course, you can also feed some cereals, herbs and so on, in order to supplement nutrition.
