(2) Packing and binding galvanized shaft wire order notes: ① the galvanized iron wire shall not be damaged when the tightening. (2) Stop the use of more than two strands of galvanized iron wire around the operation method. ③ The diameter of galvanized wire for pulling should not be less than 4mm, and the diameter of galvanized wire for binding should not be less than 2.6mm. (4) Galvanized iron wire shall not be used as waist hoop down reinforcement, usually not used as a whole binding. Warehouse galvanized wire is mainly used to block and distinguish the function of the area, warehouse galvanized wire is one of the primary use of galvanized wire, warehouse galvanized wire primary layout features are as follows: layout: Column mesh frame, column to choose square steel pipe, galvanized wire frame is also a small square pipe as the data, column and mesh frame corresponding direction are welded connecting ear piece (flat iron), column and mesh frame through the connection of the ear piece bolt fixed, column bottom welding plate, column bottom plate through expansion bolts and fixed on the ground.
Sodium and magnesium contain less combustible impurities, and when extinguished, they simply glow. Galvanizing belongs to the electrochemical processing process which is widely used on the surface of steel. So it is, first of all, because zinc coating (especially after supplementary processing, such as chromate treatment and phosphating) resistance to atmosphere and water is more stable, and the galvanized process itself this is cheaper and simple.
Galvanized iron wire is very common in practical application, some people think that galvanized iron wire will not rust, in fact, it is not. Metal corrosion is caused by the chemical or electrochemical action of the surrounding medium. According to different media, it is divided into atmospheric corrosion, soil corrosion, seawater corrosion, bacterial corrosion and so on. Atmospheric corrosion is more common, because metal products in the process of processing, transportation and storage, when in contact with the atmosphere, there are always atmospheric corrosion conditions.
There are too many fake things on the market now, so shoppers should learn how to distinguish the quality of galvanized wire, the right to protect their consumers’ rights and interests. Galvanizing process of galvanized wire products is a very effective metal anticorrosion method, and it is also widely used in other industrial fields. After galvanizing, iron wire is commonly used in metal structure equipment of various industries.
Because of the high carbon content, simple cracks occur during water quenching, so double liquid quenching (water quenching + oil cooling) is mostly used, and oil quenching is mostly used for small cross section parts. This type of steel is generally used after quenching by medium temperature tempering or normalizing or in the surface quenching state. Mainly used for manufacturing spring and wear-resistant parts.
The decorative hook mesh is made of stainless steel, aluminum alloy, brass, red copper and other alloy materials by special technology. It is to do a good decorative screen, today we introduce the aperture and wire diameter of decorative hook mesh.
Stainless steel hexagonal network is composed of machine will be produced stainless steel wire of a kind of metal mesh, not easy corrosion, the survival of the fixed number of year is longer, net of wide, coarser size, strong practicability, flexibility and other unique places, stainless steel hexagonal wire netting material is stainless steel wire, wire diameter because stainless steel wire big viscosity of large stainless steel hexagonal network would be hard to manufacture, Of course, it is more difficult to hold the edge or twist the edge, so stainless steel hexagonal mesh whether from the material or artificial are expensive, but stainless steel hexagonal mesh will not rust and use years is also very long, appearance without disposal can achieve the use effect.
There are three methods to detect the thickness of zinc layer of galvanized wire: weighing method, cross section microscopy method and magnetic method, among which the first two experiments will cause certain damage to galvanized wire, including the length of galvanized wire and the reduction of dosage. The general detection of galvanized wire galvanized layer is detected by magnetic method, which is also a more intuitive and convenient method. The standard of galvanized layer thickness is related to the wire diameter of galvanized wire. The larger the wire diameter of galvanized wire, the thicker the galvanized layer is. It is the thickness of galvanized layer and cast iron after centrifugal separation.
The characteristics of galvanized hexagonal net: easy to use; Save transportation costs. It can be shrunk into small rolls and involved in moisture-proof paper packaging, taking up little space. Coating thickness uniformity, stronger corrosion resistance; The construction is simple and does not require special technology; Strong resistance to natural damage and corrosion resistance and adverse weather effects; Can withstand a large range of deformation, and still not collapse. It has the function of fixed heat preservation and insulation.
The coating of electrode plays a very important role in the welding process. If adopting the light of the coated electrode welding, is in the process of welding, oxygen and nitrogen in the air can invade the molten metal, the metal iron and beneficial elements carbon, silicon, manganese oxide and nitride oxide and nitride formation, and remain in the weld, weld slag or crack. And melt into the molten pool in the gas can make the weld produces a large number of pores, these factors can make the mechanical properties of the weld is greatly reduced, at the same time to make the weld brittle.
