Galvanized wire coating rough, passivation film is not bright, bath temperature is too high. If the cathode current density is too high, zinc content in the bath is too high or sodium hydroxide and DPE content is too low; Electroplating solution with solid particles or excessive foreign metal impurities, will lead to such problems. Solution: If the large roll galvanized wire to the above coating is rough, there may be solid particles in the plating solution. If the roughness of the part is severe, the current density may be too high.
- Pressure welded steel grid plate is the steel grid plate fixed by pressure resistance welding at each intersection of bearing flat steel and transverse bar, which is called pressure welded steel grid plate. Torsion torsion square steel is generally used for cross bar of pressure welded steel grid. Although they do not belong to the same variety, but in the steel lattice plate standards and performance are still the same.

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.

Unless the stainless steel blade barbed rope is specially customized, it is usually produced by the mould with the knife length of 22mm, which is the BTO-22 type we usually call. This is not necessarily the specification from 11mm to 65mm are specifications. Unless the customer insists on customized length requirements, the barbed rope manufacturer will produce BTO-22 stainless steel blade barbed rope.

Post time: 14-12-22 - After the appearance of barbed wire black spots, you can choose the appearance of treatment to deal with this problem, such as galvanized, spray painting, dip plastic to deal with, after the appearance of welding mesh appearance smooth and bright, beautiful and generous.

Stainless STEEL HAS THE ABILITY to resist ATMOSPHERIC OXIDATION – that is, rust resistance, but also has the ability to resist corrosion in the medium containing acid, alkali, salt – corrosion resistance. However, the corrosion resistance of the steel varies with its chemical composition, additive state, service conditions and environmental media type.

Wire flexibility and elongation is good, can withstand the pressure of mechanical operation, in our country’s industry has played a very important role. There are many kinds of iron wire, the most common is to give black iron wire, galvanized iron wire. The corrosion resistance of the outer coating is effectively improved, but the phenomenon of crevice corrosion will be found after long-term use.
- The cage should be strong so that the bars cannot be bent or damaged by the parrot, and weak bars can be bent or damaged by the parrot and injure the parrot. Cages made of plastic coated railings can cause parrots to eat the coating and are not suitable. Quality cages are made of stainless steel, especially those made of colorful mild steel railings. Railing spacing is very important for the parrot’s safety, and the railing should always be small enough to prevent the parrot from poking its head out between the railing gaps. For small parrot species, column spacing of 1/2 inch (1.3 cm) is necessary. Medium parrot species such as grey parrots and Amazons require a 1 inch (2.5 cm) pitch, while great macaws can reach a pitch of more than 1 by inch (3.8 cm).
- 4. Substrate material: The substrate material of electrogalvanized wire also has a certain impact on its corrosion resistance. The substrate of different materials has different chemical properties and electrochemical activities, and the corrosion performance is different under different environmental conditions, and the compatibility with zinc layer will also have a certain impact on the corrosion performance.

Post time: 24-05-23 - Steel mesh plastic sprayed: Coating is also we often speak of electrostatic powder spraying coating, it is to make plastic powder charged with static electricity generator, adsorption in the iron plate or other product appearance, and then through 180 ~ 220 ℃ baking, make powder agglomeration adhesion of metal or other objects, plastic product used for indoor use more boxes, paint film present flat or matte effect. Spray powder mainly acrylic powder, polyester powder and so on.

Post time: 03-08-22 - Compared with the traditional braided barbed rope, the blade barbed rope has a relatively complex technology and a relatively high cost of raw materials.

For mountainous or hilly areas where the ground is more undulating set up stakes. You need to set a stake at the beginning and the end, and then determine the position. In the middle of the ups and downs, to increase the stakes according to the complexity of the ups and downs of the terrain, we need to be able to see 3 stakes at the same time, so that the installation is. It’s a straight line.

Greenhouse steel pipe is mainly made of greenhouse composite materials made of pull rod, pressure rod, column, and arch rod to cover the plastic film in a greenhouse. Wire factory introduces its this shape is circular plastic greenhouse, this greenhouse covers a large area, the effect of heat absorption is also very good, convenient to build, the cost of building a is also very low. The raw material source of greenhouse steel pipe is very rich and extensive, and the application effect is good.
- Cages are more often used for large dogs, which have a lot of strength. The crate must be strong, or the dog will easily break out of the crate.

Post time: 20-10-22 - 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.

When the pet consignments need to use a special pet cage, usually domestic pet cage are not qualified. Prior to shipment, the pet must be taken to the airport for quarantine inspection. The quarantine certificate should be attached to the waybill. After confirming your flight, arrive at the airport at least 3 hours in advance, anticipate the waiting time and flight time, prepare enough water and food for pets, hot weather, poor ventilation, etc., will cause harm to pets. Those who want to take pets with public transport, must go to the animal quarantine station, with proof of immunity for the county animal quarantine certificate. Clean and disinfect the pet carrier.

Through the maintenance of galvanized wire, it can not only greatly prolong its service life, but also improve its efficiency in the daily use process. Because the labeled electrode potential of zinc is -0.762v, which is negative than iron, zinc becomes the anode when the galvanic cell is formed after being corroded by the medium. It itself is dissolved to protect the steel matrix. The duration of the protection of galvanized wire layer has a great relationship with the thickness.

The number of each bundle of the blade barbed rope is 50, which is reduced by hydraulic compression and thus more convenient for loading and unloading. The forklift can load and unload easily. Under normal circumstances, when the export will be packaged and sold, so that the volume occupied in the container is relatively small, it can be easily placed and will not take up much space.
