Post time: 25-05-23Fence use: generally used as a fence is a plastic-impregnated welded wire mesh with a height of 1.2 meters to 2 meters. Most of the mesh holes are 6cm, and the wire diameter varies from 2mm to 3mm.
- Hot dip galvanized steel wire surface smooth, smooth, no cracks, joints, thorns, scars and corrosion, galvanized layer uniform, strong adhesion, corrosion resistance lasting, toughness and elasticity is excellent. The tensile strength should be between 900Mpa-2200Mpa (wire diameter Φ0.2mm-Φ4.4mm). The number of torsion (Φ0.5mm) in more than 20 times, repeated bending should be more than 13 times. The thickness of galvanizing is thin, usually only 3-15 microns, bright, smooth, beautiful appearance, poor corrosion resistance, generally a few months will rust.
- 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.
Post time: 28-12-22- In addition to these reasons, we should also pay attention to the tooling and process must be stable, and regular testing should be done to ensure the uniformity of galvanized layer.
- The application of electric welding network is more and more widely, and the technology is gradually mature, electroplating rust prevention, plastic processing, used for breeding, grille, coupled with the framework made of guardrail network.
- Galvanized wire for welding is generally required to have a certain hardness, after acceptance of galvanized wire, feel is the first thing to do, in addition to the machine test, because the average user does not have testing equipment, on the machine trial is also a very inconvenient way to test. The diameter of electric galvanized wire is measured with a micrometer, and it is kept at about 0.02mm above and below the contract signing standard, with neat appearance, no leakage plating and no messy wire.
Large volume galvanized wire is made of high quality low carbon steel wire rod processing, is made of high quality low carbon steel, after drawing molding, pickling rust removal, high temperature annealing, cooling and other processes. Galvanized wire has good toughness and elasticity, the amount of zinc can reach 300 grams/square meter, with thick galvanized layer, strong corrosion resistance and other characteristics. Widely used in construction, handicrafts, silk screen preparation, highway guardrail, product packaging and daily civil and other fields. Galvanized wire is divided into hot galvanized wire and cold galvanized wire (electric galvanized wire).
When large rolls of galvanized wire are used to bind and reinforce the goods, corresponding binding methods should be selected according to the fastening node conditions of the strengthened goods, such as opening binding, opening binding, insertion binding and so on. The insulation layer of semi-hard and soft insulation products shall be based on the diameter of the steel pipe and the size of the equipment. Large rolls of galvanized wire or glue are tied together with a width of 60mm. The binding interval of semi-hard insulating products shall not exceed 300 mm; The larger length of felt and cushion shall not exceed 200mm, and the number of belts shall not be less than 2.
The service life of the original galvanized iron welding mesh is very limited. Generally, good iron railings can only be used for about 2 years, and then renovated until the service life, which is not only time-consuming but also has safety risks. After the appearance of zinc-steel railings, the service life has been increased to a great extent in the post-processing. Generally, it can be used for at least 20 years. To improve the service life of zinc steel railings, we first have a brief understanding of the product characteristics of railings. Then from the maintenance aspect, it is necessary to maintain. Maintenance method of electric welding mesh:
Pet cage is generally made of high quality iron wire, low carbon steel wire, stainless steel wire welding, which is characterized by beautiful, lightweight, folding, easy to store. The surface treatment of pet cage is generally: cold galvanized, hot galvanized, spray, dip, chromium plating, nickel plating and other methods.
The characteristics of these cages are small, light, easy to carry and easy to clean. For small animal cage, the wire diameter of the general iron wire is not very large, the thickness of the plastic is relatively thin, so the use of the time can not be “violence”, otherwise the cage in the “destruction” will occur under the welding or plastic crack.
Steel mesh jinsu appearance treatment: polyethylene thermoplastic powder coatings is also called polyethylene powder coating, is the high pressure polyethylene (LDPE) as the basic material, adding a variety of function additives, colors, its antiseptic powder coating manufacturing processes, jinsu coating layer has the function of chemical, shock, circuitous, acid, salt fog corrosion, decorate a function and has good appearance.
- Black iron wire is mainly used in the construction industry, handicrafts, woven screen, product packaging, parks and daily life used to tie the wire. Hot dip galvanized wire is processed from low carbon steel wire rod, which is processed through drawing molding, pickling and rust removal, high temperature annealing, hot dip galvanized and cooling, etc. Hot dip galvanized wire quotation, market
With the development of mining industry, pig iron classification in Our country has been very extensive, can satisfy the demand of machinery industry. In general, iron used to produce large coils of galvanized wire can be divided into two classes. A metal produced directly from iron ore and iron smelting, consisting of iron oxide, silicon dioxide, and other miscellaneous stones. When this ore is specially refined into metal iron, carbon, silicon, manganese, and other elements are mixed in, so that the refined material is called general pig iron, is also for the initial grade of the material.
Post time: 30-06-22The use of bundled galvanized wire with the development of industry and agriculture also expanded accordingly. Therefore, galvanized wire products in the industry, such as chemical equipment, oil processing, Marine exploration, transport, electricity, shipbuilding, metal structure, etc.), agriculture (such as sprinkler irrigation, dim room, building (such as water and gas transport, wire casing, scaffolding, house, etc.), Bridges, shipping, etc., has been widely use in recent years. Because galvanized wire goods have beautiful surface, good corrosion resistance and other characteristics, its use scale is more and more extensive.
Post time: 28-01-23Wet air in rain and snow climate, steel mesh sheet exposed, easy to rust, to avoid affecting the use of steel mesh, it is necessary to carry out simple rust prevention treatment, of course, slight rust float will not affect the use of steel mesh. Common network site storage, rainy days, heavy snow, rainy days and rainy days, how to better save the steel mesh, this is a lot of friends need to consider.
- Generally speaking steel does not rust easily with chromium content of 10.5%. The higher the content of chromium and nickel, the better the corrosion resistance, such as 304 material nickel content in 8-10%, chromium content of 18-20%, such stainless steel in general is not rust.
1. The surface of the stainless steel pet cage is deposited with dust or alien metal particles containing other metal elements. In the humid air, the condensed water between the attachment and stainless steel will connect the two into a micro cell, which causes the electrochemical reaction and the protective film is destroyed, which is called electrochemical corrosion. To avoid this situation, as long as the stainless steel surface is clean, you can ensure that the stainless steel pet cage does not rust.
The 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.
Galvanized hexagonal net is a kind of galvanized metal wire mesh, mesh shape is hexagonal.
After electric galvanizing hot galvanizing. Electroplated copper and other common applications of screen consumption. The weaving of the binding of the building steel wire mesh has the first braided after plating, plating after weaving and other methods, after the disposal of the wire mesh or wire mesh has good corrosion, oxidation resistance characteristics, can be used in the construction, petroleum, chemical, aquaculture, garden protection, food processing and other industries of reinforcement, protection and insulation.
