  • 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.

  • The whole welding process of galvanized steel wire mesh does not need special technological methods, good weldability. However, in a few cases, the welding process will present difficulties: the converter steel produced by the old smelting method has high nitrogen content and high impurity content, resulting in high cold brittleness, added aging sensitivity, lower quality of welded joints, and poor weldability.

  • What are the differences between the hook fence net production plant used on the highway? The guest soil of galvanized zigzag net creates favorable conditions for the growth of vegetation on the slope. Its composition varies with the growth conditions of plants on the slope. According to the side slope rate, geological conditions, temperature, precipitation and other characteristics of reasonable selection of net types, galvanized hook mesh on the slope vegetation protection effect will be better. Highway and railway galvanized hook mesh, through the vegetation developed root system and mesh body closely combined, to achieve the purpose of protection of highway slope. The guest soil of galvanized zigzag net creates favorable conditions for the growth of vegetation on the slope. Its composition varies with the growth conditions of plants on the slope.

  • Electrode structure: portable non – electrode, including cylinder, tube, sleeve plug. Explosive welding flux by high fever agent and additives such as metal or metal oxide powder forming technology; Commonly used medicine tube paper tube. It can also be used for different weldment and use environment, use metal pipe, etc; Plug at the end of the electrode, which is with casing welding clamping position of the match, and stop welding flux leakage from the tube.

  • One end of the wire must be clearly marked and the other end left on the outer layer for easy connection by other wires. 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 bird cage is the main environment for the birds to live and live in. Only with proper cage and other accessories, can the birds be kept healthy and lively, singing freely and suitable for viewing.

  • Heavy duty hexagonal mesh made of steel wire by special machinery woven into a hexagonal mesh net. This kind of mesh can be cut and assembled into fence mesh, mountain hanging mesh, vegetation three-dimensional mesh, composite, etc.

  • Plastic spraying is also known as electrostatic powder spraying. It is the use of electrostatic attack device to make plastic powder charged, adsorbed on the surface of the iron plate, and then through the baking of 180~220℃, so that the powder can be melted and adhered to the metal surface. Plastic spraying products are mostly used in the indoor box, and the paint film appears flat or matte. Spray powder mainly acrylic powder, polyester powder and so on.

  • Stainless steel material refers to air, steam, water and other weak corrosive medium and acid, alkali, salt and other chemical corrosive medium corrosion of steel, also known as stainless acid-resistant steel. In practical application, the steel that is resistant to weak corrosive medium is often called stainless steel, and the steel that is resistant to chemical medium corrosion is called acid resistant steel. And galvanized wire has good toughness and elasticity, the amount of zinc can reach 300 grams/square meter. It has the characteristics of thick galvanized layer and strong corrosion resistance. Products are widely used in construction, handicrafts, silk mesh, highway fence, product packaging and daily civilian and other fields.

  • The surface of the galvanized wire deposition layer before galvanized to remove the surface film layer, surface inclusion and other defects to the local, can be found and treated by conventional technology. Excess foam is caused by soaps and saponable fatty surfactants being brought into the tank. Moderate foam formation rates may be harmless.

  • In summary, as a commonly used anticorrosive material, electrogalvanized wire has good corrosion resistance. Its corrosion resistance mainly depends on the thickness, uniformity and structure of zinc layer, substrate material and environmental conditions and other factors. Through reasonable electroplating process and material selection, the corrosion resistance of electrogalvanized wire can be improved and its service life can be extended.

  • The color of powder coating is divided into: razor wire blue, grass green, dark green, yellow. Plastic-sprayed blade gill net is made of hot-dip galvanized steel plate or stainless steel sheet stamped out of sharp knife sheet, high tension galvanized steel wire or stainless steel wire as core wire combination of resistance devices. Because the shape of the barbed rope is not easy to contact, so it can reach an excellent protective barrier effect. The primary raw materials of products are galvanized sheet, stainless steel plate, high quality low carbon steel wire (electric galvanized, hot galvanized, plastic coated, plastic spraying) wire, blue, green, yellow and other colors.

  • B. When the thickness of the plating is greater than 4 mm, the zinc adhesion should not be less than 610g/m, that is, the average thickness of the zinc layer should not be less than 86 microns.

  • There are many categories of large coils of galvanized wire, and different categories can be applied to different scenarios. Galvanized iron wire common application is the application of the construction industry, one is the use of binding wire, whether it is the binding of scaffolding or reinforcement, need galvanized iron wire to carry out, the common specifications are 22 and 24 wire, common length of 30cm, 35cm, 40cm, 45cm, 50cm. There is also 20kg or 50kg a bundle of 18, 16, 14, 12, 10 galvanized coil wire.

  • Paint on the galvanized layer, the bonding force between each other has a great relationship with the baking temperature of the paint, and alkyd paint is coated after galvanized, and the adhesion is not a problem. After galvanized to do amino paint, paint adhesion is not very good. Do two bottom two surface, adhesion is good, if the two bottom two surface changed to two bottom three surface, that is, more paint, more baked once, again test adhesion is very bad, bad enough to tear the paint from the galvanized layer.

  • Greenhouse special electroplating process iron wire blackening solution:

  • 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.

  • 1. Avoid direct sunlight
  • The surface of alluvium before hot dip galvanizing of orchard special electric galvanized shaft wire can partially remove the surface film layer, surface impurity and other shortcomings according to the basic technology to find and solve; Excessive foam is caused by soap and soapable surface active substances such as human fat into the tank. A moderate rate of foam production would be fine. There are many fine homogeneous particles in the tank, can stabilize the foam layer, with activated carbon mat to remove surface active substances. Or make the bubble unstable according to overworry, these are all reasonable countermeasures; Other strategies should also be used to reduce the amount of surface-active substances introduced. The introduction of organic matter can make the electroplating process speed drop sharply. Although the secret recipe of organic chemistry is beneficial to the high accumulation rate, the thickness of the coating can not meet the requirements after the organic matter is brought in, so the activated carbon can be used to solve the tank.

  • Hexagonal barbed wire is divided into small hexagonal net and heavy hexagonal net. Heavy hexagonal net is also known as large hexagonal net, large size hexagonal net, mountain protective net, hanging net, stone mesh, gabion net.

  • Stainless steel barbed rope in the way of corrosion is not too, because the surface is not processed but depends on its own raw materials for corrosion resistance, so there will be no chemical reaction. After a long time of use, will not be similar to hot dip galvanized barbed rope surface corrosion coating problems will rust, because the stainless steel barbed rope internal material and the surface of the material is the same.

  • Three: packaging: moisture-proof paper, woven bag strip, other packaging can be packed according to customer requirements

  • 3. Put zinc block into the plating aid pool regularly, so that the bivalent iron in the plating aid becomes trivalent iron, and it is an important measure to stabilize the PH value in a numerical range. At the same time, it is convenient for the filter to filter out the trivalent iron ions in the plating aid; Ferric 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 play the role of plating aid filter.

  • 1. Principle. Because zinc does not change easily in dry air, and in humid air, the surface can form a very dense film of zinc carbonate, which can effectively protect the interior from corrosion. And when the coating is damaged for some reason and the matrix is not too large, the zinc and steel matrix form a micro cell, so that the fastener matrix becomes the cathode and is protected. It is widely used in automobile transportation and other industries, but what is needed is the trivalent chromium passivation layer, zinc nickel alloy plating closed coating, reduce the harmful and toxic layer of hexavalent chromium passivation.
