We must have a certain understanding of the hexagonal network, we are the beautiful appearance of the hexagonal network, hexagonal network is not only very beautiful appearance, in fact, the practical value of survival is very high. To introduce the relevant information should be very clearly know the highway guardrail net, hexagonal wire netting in all kinds of fence netting, in the value of the high-speed on the road more MaoJian, it not only be used in all kinds of road, in a sports ball games venue and try our best to take care of landslides, also has reached very matter effectiveness.
Cold galvanizing is in the plating tank through the current unidirectional zinc gradually plated on the metal appearance, the production speed is slow, uniform coating, thin thickness, usually only 3-15 microns, bright appearance, smooth, high aesthetics, poor corrosion resistance, generally a few months will rust. Hot dip galvanized coating is thicker, generally 30-60 microns, coating corrosion resistance is higher. Suitable for outdoor work of steel parts, such as highway fences, power towers, large size fasteners and other more “rough” workpiece long-term rust prevention.
- The strength, service life and hardness of positive and negative twisting rope are good. The tensile strength of steel wire is 1200N and that of iron wire is 350N. This service life is much longer than ordinary wire barbed rope.
- Galvanizing can be done by zincate galvanizing or chloride galvanizing. Appropriate additives shall be used to obtain a coating that meets the requirements of this standard. Luminescence treatment should be carried out after luminescence plating. The parts that need to be dehydrogenated for passivation should be passivated after dehydrogenation. Before passivation, 1%H2SO4 or 1% hydrochloric acid should be applied to activate 5~15s. Passivation shall be treated with colored chromate unless otherwise specified in the design drawings.
Large roll galvanized wire can be divided into hot-dip galvanized wire and cold galvanized wire, the difference between the two lies in the way of zinc and the amount of zinc. Hot dip galvanizing is to soak steel wire in melted zinc liquid, hot dip galvanizing zinc fast, zinc layer thick rust prevention performance is very good, but the zinc is not uniform, and the surface is dark, the life of hot dip galvanizing can reach 20 years.
Post time: 12-06-24When using these two products, it is obvious that there is a gap between them. By pulling or bending the wire, it is often difficult to restore the original, for example, if the same place is repeatedly bent, it will be found that it has broken, and the cold drawing wire will not. Cold drawing wire compared with iron wire, its hardness, tensile resistance, bending ability is greatly enhanced, suitable for building materials.
Post time: 28-10-22The welding between low carbon steel, low alloy steel, medium carbon steel, alloy steel and the same kind of metal materials or dissimilar metal materials can be realized. The weld has good comprehensive mechanical properties, tensile strength can reach more than 400MPa.
Plastic-coated barbed rope is not only used but also beautiful, so it is used in a large number of highway sides, and other special places, so what are the colors of plastic-coated barbed rope? Where are the plastic-coated thorn ropes of no color respectively applied?
It’s not clear why friends would want to use building nets for floor heating. What is its advantage in the floor heating project, the role of steel wire mesh is convenient for construction. Building mesh can better fix the pipe, conducive to the construction of the floor, improve efficiency. Anti-cracking function. The building network can improve the bearing capacity of the foundation of the insulation board, the thicker the diameter of the building steel wire, the greater the bearing capacity, effectively prevent the appearance of cracks and cracks of steel wire mesh can improve the thermal shrinkage and shrinkage of cement, strengthen the tensile strength of cement, improve the quality of the heating project.
- The patented technology is used to regularly put zinc blocks into the plating aid pool, so that the bivalent iron in the plating aid becomes trivalent iron, and plays an important measure to stabilize the PH value within a numerical range, and also facilitate the filter to filter out the trivalent iron ions in the plating aid; The trivalent iron ion is controlled between 0.3 and 1.0g/L; When hydrogen is not released in the plating aid, the zinc block is continued. It is an effective measure to reduce zinc slag, improve the fluidity of zinc liquid and reduce the thickness of zinc layer to give full play to the function of plating aid filter.
Hot dip galvanizing is dipped in zinc liquid melted by heating, with fast production speed and thick but uneven coating. The market allows a low thickness of 45 microns and a high of more than 300 microns. The color is dark, the consumption of zinc metal is much, the formation of infiltration layer with the matrix metal, the corrosion resistance is good, and the outdoor environment of hot dip galvanized can be maintained for decades. Application range of hot dip galvanizing: because the coating is thicker, hot dip galvanizing has better protective performance than electric galvanizing, so it is an important protective coating for iron and steel parts in harsh working environment. Hot-dip galvanized products are widely used in chemical equipment, petroleum processing, Marine exploration, metal structure, power transmission, shipbuilding and other industries, in the field of agriculture such as sprinkler irrigation, greenhouse and construction industry such as water and gas transmission, wire casing, scaffolding, Bridges, highway guardrail and other aspects, has been widely used.
A. When the thickness of the plating is 3-4 mm, the zinc adhesion should be less than 460g/m, that is, the average thickness of the zinc layer is not less than 65 microns.
- Slowly through the axial flow fan or exhaust hole directly discharged to the sand blasting room, so that the power of dust discharge is low. And in the discharge of dust because there is no further treatment, so the discharge of dust will seriously pollute the sandblasting room and the surrounding environment, the health of the site staff will also harm.
- The top of the wall is installed with ordinary galvanized barbed rope for protection. Although the effect is better, the style is not beautiful. In recent years, it has been gradually replaced by blade barbed rope. First of all, the protection ability itself does not have any point of emphasis, can not use its own climbing at the same time, due to the relatively large volume of the intention to turn over the personnel caused no small difficulty, the whole body has a spike is very easy to be scratched or hook clothes, so in this aspect of the protection ability is better. Moreover, the style of spiral cross is more beautiful than the original single style, which is more suitable for some high-grade apartments and other external walls of the fence, at the same time, it will not cause the feeling of imprisonment in the interior.
Post time: 16-12-22Now the production of stainless steel blade barbed rope unless it is a specially customized model, under normal circumstances are the use of a knife length of 22mm mold production, that is, we usually say bto-22 type. It’s not necessarily the case that there are specifications from 11mm to 65mm. Unless the customer insists on customizing the required length, the barbed rope manufacturer produces bto-22 stainless steel blade barbed rope.
Post time: 05-08-22Dip plastic six side barbed wire corrosion lost the original characteristics, in the shape, color and mechanical properties and other aspects will change, resulting in equipment damage, pipeline leakage, in particular, is prone to fracture, lose the original protective function.
Post time: 27-02-23No 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.
- 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.
