Galvanized iron wire can be divided into hot-dip galvanized iron wire and cold galvanized iron wire according to different processing methods. Galvanized iron wire is more prominent in its corrosion resistance. Galvanized iron wire has good toughness and elasticity, the amount of zinc can reach 300 g/square meter, with thick galvanized layer, strong corrosion resistance and other characteristics. Galvanized iron wire products are widely used in construction, handicrafts, wire mesh preparation, the production of galvanized hook mesh, wall mesh, highway guardrail, product packaging and daily civilian and other fields.
(2) The construction is simple and does not need special technology;Galvanized welding net is currently a large use of galvanized wire drawing products, galvanized welding net is divided into cold galvanized welding net and hot galvanized welding net. The price of cold galvanized welding net is cheaper than that of hot galvanized welding net, and the anti-corrosion performance is worse. Production process standard for cold galvanized electric welding mesh. The selection of galvanized electric welding net uses Q195 low-carbon metal wire, the wire rod is drawn by wire drawing machine.
Welding electrode has a wide range of applications, can realize a variety of materials, a variety of profiles and a variety of joint forms of welding.
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.
Surface coating, surface inclusion and other defects can be removed locally from the surface of the deposited layer before galvanized, which can be found and treated by conventional techniques. Excess foam is caused by the introduction of soap and saponable fatty surfactants into the tank. Moderate foam formation rates may be harmless. The presence of a large number of tiny homogenous particles in the tank, which can stabilize the foam layer, mat with activated carbon to remove surface active substances, or make the foam less stable through filtration, are effective measures.
Heavy hexagonal mesh can be used for slope support, mountain rock face hanging net shotcrete, slope planting green, it can also be made of stone cage cage, stone pad cage, for rivers, DAMS and seawall prevention and control of erosion and reservoirs, river interception with stone cage.1. Eliminate caked zinc residue on zinc liquid surface
There are various specifications of barbed rope, which can be divided into two categories: ordinary barbed rope and blade barbed rope.
The characteristics of large volume galvanized wire is smooth and bright surface, but wet will affect the brightness of galvanized wire, so we must pay attention to avoid humidity when storing, can support a shelf on the ground, so that galvanized wire and the ground isolation, so that it will not be affected by the surface moisture, there is to pay attention to the change of weather, to avoid galvanized wire rain. Galvanized wire has good toughness and elasticity, the amount of zinc can reach 300 g/square meter. It has the characteristics of thick galvanized layer and strong corrosion resistance.
National standards on the use of wire mesh standards have certain requirements, diameter and mesh size matching use, rather than simply diameter size, on the plaster layer to use is mesh should not be greater than 20×20, diameter is not easy to be less than 1mm, light selection diameter is not much significance, choose 40×40×0.9 and choose 10×10×0.6 wire mesh, Which one is better? 10×10×0.6, I’m afraid.In order to improve the corrosion resistance of steel pipe, the general steel pipe is galvanized. Galvanized steel pipe is divided into hot dip galvanized and electric galvanized. The layer of hot dip galvanized is thick, the cost of electric galvanized is low, and the surface is not very smooth. Used for steel blowing oxygen pipe, generally with small diameter welded steel pipe, specifications from 3/8-2 inches of eight. Made of 08, 10, 15, 20 or 195-Q235 steel strip, in order to prevent corrosion, some should be aluminized.
