- The mixture of rare earth and aluminum enhances the fluidity of zinc liquid, makes the coating more uniform, and also reduces the zinc consumption. Hot dip galvanized wire has better protection performance than cold galvanized wire, which makes it good application in chemical experimental equipment. Hot dip wire coating thicker, so that it has good corrosion resistance, can be in the outdoor sun and rain and other harsh environment can be maintained for decades, so hot dip galvanized wire is widely used in construction, traffic guardrail and other outdoor facilities.
(1) In the painting construction should pay attention to ventilation, moisture-proof, fire prevention. The working environment and painting tools should be kept clean, the pressure of the air pump should be controlled within 0.63MPa, and the safety valve should be checked for failure.
- 4. Cooling: The galvanized steel wire needs to be cooled to reduce its temperature to room temperature.
Zinc adhesion on galvanized wire surface and thickness of zinc layer
- The reason why there are black spots in wire mesh welding is that the action of wire feeding should be timely filled in the melting time, and the development should be appropriate. There is no argon gas, long burning, large current, long distance, blunt tungsten needle and high molten pool temperature are the fundamental reasons for blackening. Continuous burning, is about active welding machine energy selection, machine welding will appear black spots.
1. Used for mountain farming, road isolation, large farming enclosure protection, it is recommended that you choose 3mm wire diameter products.
Post time: 27-05-222, the production and installation is simple and fast, the use of patented friction connection or special connection accessories for installation, greatly improve the installation efficiency.
On the contrary, the denser the ion deposition, the better the quality of zinc layer. Under the condition that the surface zinc layer is dense and bright, the quality of zinc layer per unit area should reach 80g/m2, and the process parameters should be optimized as follows: current density is 16-20A /dm2, mass concentration of zinc sulfate solution is 500g/L, and pH value is 2.5-3.0.
- 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.
As we all know, the use of hexagonal net for protection can protect the natural environment while protecting the bridge, which can not only green the ecological environment, but also prevent soil erosion.
Large roll galvanized wire welding net is made of high quality galvanized wire welding net, wire through the current, after mutual melting, strong connection point, and the formation of metal mesh. In the use of galvanized iron wire to find the thickness and soft and hard to the size of flowers, weight and softness corresponding to the degree, too soft florets to use fine wire, and heavy flowers, flowers with thick stems to use thick wire.
- One is to do a good job of galvanized wire packaging, avoid bump, to ensure the integrity of the zinc layer;
- The top of the wall is installed with ordinary galvanized barbed rope for protection. Although the effect is better, the style is not beautiful. In recent years, it has been gradually replaced by blade barbed rope. First of all, the protection ability itself does not have any point of emphasis, can not use its own climbing at the same time, due to the relatively large volume of the intention to turn over the personnel caused no small difficulty, the whole body has a spike is very easy to be scratched or hook clothes, so in this aspect of the protection ability is better. Moreover, the style of spiral cross is more beautiful than the original single style, which is more suitable for some high-grade apartments and other external walls of the fence, at the same time, it will not cause the feeling of imprisonment in the interior.
- Non-proportional extension strength: It is mainly for hard steel without yield point. It is defined as the stress where the residual elongation of the standard distance part reaches 0.2% of the length of the original standard distance.
- The strength of the hook net should be satisfactory: when the vehicle is traveling at 80 km/h, the hook net will not fall into the river when it bumps against the railings at a 15 degree Angle. The shape and color of the hook mesh should be in harmony with the surrounding natural environment. The phenomenon planning of important Bridges should be done well.
- The production and processing process of blade barbed rope is tedious, which requires the cooperation of all departments, and the production cycle is relatively long. The barbed rope, whether galvanized barbed rope or stainless steel barbed rope, due to the relatively simple structure, the degree of mechanization in the production process is relatively high, so this is also a big difference in the price.
As we all know, the mechanism of resistance to atmospheric corrosion of zinc includes mechanical protection and electrochemical protection. Under the condition of atmospheric corrosion, there are ZnO, Zn(OH)2 and basic zinc carbonate protective film on the surface of zinc layer, which to a certain extent slows the corrosion of zinc. When this protective film (also known as white rust) is damaged, a new film will be formed.
Post time: 26-07-22Common galvanized iron wire equipment is usually used in barbecue net, barbecue net generally requires to have a long service life, with galvanized iron wire equipment to wire a layer of zinc, barbecue net is not easy to be corroded.
The use of packaging galvanized wire with the development of industry and agriculture is also expanded accordingly. Therefore, galvanized silk commodities have been widely used in industry (such as chemical equipment, petroleum processing, Marine exploration, metal structure, electric power transportation, shipbuilding, etc.), agriculture (such as irrigation, heating houses), construction (such as water and gas transportation, wire casing, scaffolding, houses, etc.), Bridges, transportation, etc., in recent years. Because galvanized silk products have beautiful surface, good corrosion resistance and other characteristics, its use is more and more extensive.
- Both sides of the galvanized welding net exposed can not be more than 2mm, so as to be qualified. And in the welding mesh of each warp and weft wire cross place, must be welded very firm, and if you want to welding very firm, both sides must have some warp and weft wire out, and the length must be controlled within two millimeters. From the mesh distribution is not uniform, galvanized is not uniform, but also to see whether the welding mesh is qualified standards.
- Smelting technology is good, advanced equipment, advanced process of large stainless steel plant whether in the control of alloy elements, impurities removal, billet cooling temperature control can be guaranteed, so the product quality is stable and reliable, good internal quality, not easy to rust. On the contrary, some small steel equipment is backward, backward process, smelting process, impurities can not be removed, the production of products will inevitably rust.
- Barbed wire manufacturers focus on galvanized barbed wire, hot galvanized barbed wire, blade barbed wire, stainless steel barbed wire, plastic coated barbed wire, reverse screw barbed wire production for ten years.
Spring steel wire should have high tensile strength, elastic limit, endurance and fatigue strength, and resistance to impact and oscillation. The strength and endurance objectives, especially to prevent the occurrence of modification cracks, are the key to the consumption of spring wire. The inner quality and outer quality of the wire rod directly affect the function of the wire.
- Galvanized hexagonal net is a kind of galvanized metal wire mesh, mesh shape is hexagonal.
Hot dip galvanizing is dipped in zinc liquid melted by heating, with fast production speed and thick but uneven coating. The market allows a low thickness of 45 microns and a high of more than 300 microns. The color is dark, the consumption of zinc metal is much, the formation of infiltration layer with the matrix metal, the corrosion resistance is good, and the outdoor environment of hot dip galvanized can be maintained for decades. Application range of hot dip galvanizing: because the coating is thicker, hot dip galvanizing has better protective performance than electric galvanizing, so it is an important protective coating for iron and steel parts in harsh working environment. Hot-dip galvanized products are widely used in chemical equipment, petroleum processing, Marine exploration, metal structure, power transmission, shipbuilding and other industries, in the field of agriculture such as sprinkler irrigation, greenhouse and construction industry such as water and gas transmission, wire casing, scaffolding, Bridges, highway guardrail and other aspects, has been widely used.
