- Drill Rods These are the connecting links between the surface rig and the drill bit, allowing for the transmission of energy and air.
- Take 20cm galvanized wire for acid fog experiment, check the zinc content of galvanized wire through the balance to see whether it meets the zinc layer standard required by the customer, ensure that the metal wire can achieve the role of rust and corrosion prevention, and meet the service life required by the customer. Galvanized iron wires must be packed in good condition, bound neatly and orderly, and bound with an inward end to prevent scratches during transportation. The inspection standard of galvanized iron wire also includes the tensile test. This item is determined according to the material of the galvanized wire order ordered by the customer, and it needs to be tested by comparing the raw material list.
- 4. When the dog is tired or nervous, it can enjoy its own private space in the cage and let it have a good rest.
- The electrolytic deposition of large roll galvanized wire zinc-chin layer is basically the following two kinds of electrolyte: zinc is mainly in the form of zinc cation hydration in the solution; Zinc is mainly present in solution as complex anion. Acid electrolyte belongs to one class, complex cyanide and zincate electrolyte, and nickel sulfate electrolyte constitute the second class. Cyanide electrolyte and acid electrolyte are of great significance.
- Choose a well-structured crate, such as one with a tray under it so the dog can pee and defecate in it. It’s also easy for the host to clean up.
Post time: 19-05-22Removal of surface-active substances by activated carbon matting. Or make the bubble unstable according to overworry, these are all reasonable countermeasures; Other strategies should also be used to minimize the amount of surfactant taken in. The introduction of organic matter can make the electroplating process speed drop sharply. Galvanized iron wire blackening can be effectively prevented, such as: the work site to keep dry, reduce and do not use chemicals, operators with clean gloves and so on. In addition, hot dipping zinc factory can be required, after dipping zinc must be passivation treatment, passivation treatment of zinc has a better anti-discoloration effect, can effectively prolong the discoloration time, the combination of the two, discoloration should be able to solve.
On the highway, barbed rope protection net is generally to prevent people and animals from crossing the highway at will, so as not to interfere with driving and reduce accidents, as well as effectively prevent illegal occupation of road land and other issues of traffic safety facilities. There are many forms of barbed rope protective nets, commonly used metal, woven net, barbed wire and often green gracilaria. Metal braided net is set in crowded areas, barbed wire is used in areas with few people and animals, and the structure of hedges and barbed wire is used in toll stations and service areas. In the past two years, considering the beauty of the problem, in the Pearl River Delta region of some highways with fruit plastic spot welding network (usually said guardrail network), this barbed rope protection network is more good-looking, durable, the overall effect is good, but the construction requirements are higher, more expensive. General sections should not be used, in the city center, scenic spots or strong requirements for beautiful sections can be used.
- Reverse twist: Twist the barbed wire in the opposite direction from where the nematocyst is wound around the main wire. It’s not twisted in one direction. It’s called the reverse twist.
- 1, the width and length of the hexagonal net (according to your actual needs, we can adjust the width and length flexibly).
Two, the production process is different
There are many important details that need to be paid special attention to during the production of barbed rope or blade barbed rope by the barbed rope factory. If any improper, it will cause unnecessary losses.
- The galvanized requirements of the parts to be plated: the surface of the parts to be plated should be smooth, and there is no dirt that cannot be removed by pickling method. Such as paint, grease, cement, asphalt and excessive rotten harmful substances; All welds of welded components shall be sealed without air; Pipe fittings and containers must have exhaust and zinc inlet holes; The workpiece should be finished welded steel pipe without thread, if any thread should be protected.
During this process, each time the wire is pulled over, the surface hardens due to the high friction temperature. So basically every time you pull it you have to annealing it in the furnace. On the one hand, it is to reduce the surface hardness. On the other hand, during the process of wire pulling, only the surface is deformed, and the center is unchanged. So there’s a lot of stress inside. Therefore, it is necessary to rely on annealing to eliminate the internal stress, so that the wire becomes soft again to eliminate the stress before being drawn again.
3. Acid activation acid activation solution should be able to remove corrosion products and oxide film (skin) on the surface of parts, without excessive corrosion on the matrix.
- Ring corn with: used as a ring corn net, generally use mesh 5cm*7cm or 5cm*5cm of the original galvanized welding net, wire diameter from 1.8mm-2.3mm, height of 1.2m – 1.8m.

Post time: 25-07-22- Compared with hot-dip galvanized barbed rope, it is much better in the circle of mountains and forest protection. Because it can choose several colors on its appearance, different sites have different colors, which is both beautiful and practical, so as to facilitate the growth of natural plants and gradually recover the original ecological environment.
Poor pretreatment before electroplating; Bath temperature is too low; Poor quality additives or excessive additives and organic impurities can cause poor bonding. The quality of the additive also has an effect on coating foaming. Some additives react incompletely during synthesis and continue to polymerize during long-term storage or use. The additive tends to distort the lattice and create stress, causing the coating to blister.
- At present, blade barbed rope has been widely used in industrial and mining enterprises, garden apartments, border posts, military fields, prisons, detention centers, government buildings and other national security facilities in many countries.
Post time: 04-11-22One is to do a good job of galvanized wire packaging, to avoid bumping, to ensure the integrity of the zinc layer;
For example, in gray iron, its carbon exists in iron ore in the form of graphite, the crack is often gray, soft and tough, simple filter cutting, suitable for casting. In the white iron, the carbon and iron are combined to form iron carbide, the crack appears white, the quality is very strong and brittle, and it is the material of malleable steel. Alloying grade is composed of various alloying elements with different composition and structure.
- Material: low carbon steel wire
The production process of large rolls of galvanized wire is a level of drawing, through the mold into a slightly smaller diameter than the original. And so on down to the desired length. One pull is not desirable, must be numbered, from coarse to fine is dependent on metal ductility. If it changes too much it just breaks. After drawing to a certain diameter, galvanized, so that the finished product.
