Post time: 25-05-23The welding core is the metal core of the electrode. In order to ensure the quality of the weld, there are strict regulations on the content of various metal elements in the weld core. In particular, there are strict restrictions on harmful impurities (such as sulfur and phosphorus), and the quality of the weld core metal should be better than that of the base metal. Arc welding cannot be carried out on a smooth rod without a coating. This is because the arc stability is very poor, splashing is very large, and the weld is not well formed. After long-term practice, it is gradually found that the performance of the electrode is greatly improved by coating the welding core with some mineral raw materials (i.e. electrode coating). (1) Ensure stable arc combustion, so that the welding process is normal. (2) Using the gas produced after the drug skin reaction, protect the arc and the molten pool, prevent the harmful gases in the air (such as nitrogen, oxygen, etc.) from invading the molten pool, such as these gases will cause cracks and pores in the welding material, so that the welding can not achieve the ideal effect. (3) After the drug skin is melted, slag is formed, which covers the weld surface to protect the weld metal, make the weld metal slowly cool, help the gas escape, prevent the generation of pores, and improve the structure and performance of the weld. (4) After melting, various metallurgical reactions will be carried out, such as deoxygenation, sulfur removal, phosphorus removal, etc., so as to improve weld quality and reduce alloying element burning loss.
Spray powder mainly acrylic powder, polyester powder and so on. Dipping is a kind of plastic coating process, that is, the plastic coating on the matrix, generally metal, such as: daily use of clothes hangers, pliers handles, scissors on the rubber sleeve, various handrails, etc. Plastic immersion is to heat the metal to spray plastic powder evenly on the metal to form a plastic film, or heat immersion liquid into the metal to cool it and then plastic coating on the metal surface.
Post time: 15-02-23The 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.

Post time: 24-11-22- 2, galvanized wire mesh molding sheet storage ground should be flat, according to the symbolic requirements of the accumulation of regular, height should not exceed 2M, and away from heat sources, avoid exposure.
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).
- Positive twist: Twist two or more pieces of wire into a double wire rope and then wrap the wire around the double wire. It’s called a positive twist cord which is a common double strand cord.
(1) The application method of packaging and binding galvanized shaft wire ordering: ① the pulling position on the goods should be reasonably selected. When used to avoid horizontal movement of goods, the pulling position should be as low as possible; When used to avoid overturning the goods, the pulling position can be appropriately high. ② The use of galvanized iron wire [1] pull reinforcement methods mainly include: figure eight, inverted figure eight, cross, zigzag or reverse zigzag and so on. Various pull methods can be used alone, but also two or more than two kinds of use. The pull should be as symmetrical as possible. (3) When pulling reinforcement, the single or double strands of galvanized iron wire will reciprocate around the goods and vehicles between the two tying nodes, and should be pulled tight galvanized iron wire so that the tightness of each strand is as common as possible, and some of the remaining cross around its own rope rod, and the rest of the tail toward the car.
- And the role of wire mesh in the exterior wall plastering if from an Angle of anti-falling method, the effect of anti-cracking is relatively small, because of the azimuth problem; And about the external insulation system is used in the brick veneer, as for the role should also be anti-drop followed by anti-cracking, so we should choose the grid 10×10×0.6, these are some experience selection, the conversion of the grid comes from the national standards of steel wire mesh, the selection of steel content of the grade conversion.
- 5, there are no special requirements: such as whether to shrink packaging.
First, galvanizing can enhance the corrosion resistance of the product. Zinc has high potential and excellent anodic protection. When the surface of the product is galvanized, zinc will have an electrochemical reaction with oxygen and water in the environment, thereby forming a dense zinc oxide protective film, preventing the metal from further contact with external oxygen, water and other substances, slowing the corrosion rate of the metal. Galvanized products after wire drawing processing, because the surface of the product has a more dense zinc oxide protective film, it can better resist external corrosion and improve the corrosion resistance of the product.
- 2. Breeding chickens, ducks, geese and other small animals, fruit and wood garden enclosure protection, medium breeding protection, it is recommended that you choose 2.3mm-2.5mm wire diameter products.

Cold galvanizing, also called electric galvanizing, is the use of electrolytic equipment to remove oil, pickling, after the pipe fitting into the composition of zinc salt solution, and connected to the negative electrode of the electrolytic equipment. Wire factory on the opposite side of the pipe fittings placed zinc plate, connected to the positive electrode of the electrolytic equipment is connected to the power supply, the use of current from the positive electrode to the negative electrode will deposit a layer of zinc on the pipe fittings, cold plating pipe fittings is first processed after galvanized.
- 2. Dissolution treatment: Put the pickling steel wire into the dissolution tank, and dissolve the zinc powder with the bath liquid by heating, and the dissolved zinc liquid will adhere to the surface of the steel wire.

Post time: 12-07-22Stainless steel barbed rope in the way of corrosion is not very, because the surface is not treated but rely on its own raw materials for corrosion resistance, so there will be no chemical reaction.
- Ask the factory to provide the corresponding quality inspection report before packing. Cold drawing is a kind of material often used in our life, especially in the construction of buildings. Cold wire drawing is used more in building materials, cold wire drawing testing standards are also different. The strength of cold wire drawing is high, and it can be used in many aspects. Where plasticity is not required, only strength is required, such steel can be used.
The barbed rope factory not only provides the sales work of blade barbed rope, including the subsequent construction, but also contracted together, and the construction price is particularly different.
Post time: 08-08-22- The application range of small hexagonal net is also relatively wide, can be used for building wall fixed insulation layer, pipeline, boiler fixed insulation, decoration and other fields.
Post time: 07-07-22Hot-dip galvanized wire has longer service life and better corrosion resistance than ordinary steel wire. Hot dip galvanizing is a method of chemical combination of zinc metal and steel wire surface, through the formation of a strong and self-healing zinc-iron alloy protective layer on the steel wire surface, so as to prevent direct contact between the steel wire and the external environment, reduce the possibility of oxidation corrosion, and extend the service life of the steel wire.
