The hook mesh is a good material for flood control and flooding. Can also be used for arts and crafts manufacturing, mechanical equipment transport network mountain beautification network – high strength steel wire grid (hook mesh, diamond mesh) hook mesh mountain protection application principle, hook mesh interests, mesh uniform, flat, woven concise, hook woven, beautiful and generous, net, net width, wire diameter is thicker, not easy to corrosion, long life, strong usefulness.
The steel mesh is also called longitudinal reinforcement and transverse reinforcement. The longitudinal reinforcement and transverse reinforcement are spaced at right angles to each other, and all the crossing points are welded together. It has the characteristics of crack – proof, small error and good quality. Steel mesh is mainly used in coal mine roadway, concrete pavement, bridge deck, airport runway and buildings. So, what are the advantages of mesh?
After annealing, the wire will become soft, flexibility will increase, iron is a relatively active metal, and more active than hydrogen, so it is a good reducing agent. At room temperature, iron is not easy to react with oxygen, sulfur, chlorine and other non-metallic elements in dry air. Its production cost is lower, its use and scale are also relatively wide, and it has better protective function. Therefore, it is an important material for steel parts in strict working environment.
That said, it can always deform by pulling hard without changing its integrity, so cold drawing has usually reached a limit, which is not a problem, because without this property it increases hardness, which is the desired effect. Cold wire drawing encountered more rain, when the climate is wet, easy oxidation and rust. Therefore, in the storage process should pay attention to avoid rust.
2) wire spacing: we all know that the smaller the wire spacing, the stronger the cage, in fact, too close is not good, too close to the dog will have a feeling of repression, we recommend that you buy wire spacing between 15-25mm, so it is not too close, and not too loose.
When the coating of large galvanized wire is blistered in the process of galvanizing, the bath temperature should be checked first. If the bath temperature is not low, and then strengthen the removal of oil before plating, to prevent the base metal in acid corrosion. If you pay attention to these problems, the bubbling phenomenon still exists, it should pay attention to the dosage and quality of additives, then you can stop adding additives, with high current electrolysis for a period of time, to reduce the content of additives, observe whether the bubbling phenomenon is improved. If there is no improvement, check whether the additive has been stored for too long or whether it contains too many impurities.
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.
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.
