Steel mesh manual binding line of the joint simple sliding, steel and concrete strength is weak, simple crack. The welded joint can accept not only pressure but also shear force. Longitudinal and transverse steel bars form a network structure, which plays a bonding anchorage effect. The number of solder joints per unit area is added when the diameter of the wire mesh is small and closely spaced. More conducive to strengthening the crack resistance of concrete, can reduce more than 75 percent of the attack of steel mesh cracks is a new, energy-efficient steel mesh structure, used in beams and columns, floors, roofs, walls, concrete pavement, bridge deck paving and other industrial and civil buildings.
The price of galvanized iron wire is relatively low, but the corrosion resistance is excellent, so it is favored by many screen businesses. In the production process of galvanized iron wire, first of all, we should check the equipment to see if there are any problems, and then we should look at the galvanized process, whether there are factors that cause product discoloration. If these problems do not exist, or some of them occur on the same equipment, and some are normal, then we should consider the problem of raw materials at this time.
Post time: 05-06-23From the point of view of spray, spray blade gill net (PVC blade gill net, coated blade gill net) is also called spray blade barbed wire, spray blade barbed wire is the blade barbed wire produced in the future, to carry out anti-rust treatment. Spray surface treatment to make it has quite good anti-corrosion ability, beautiful appearance, good waterproof effect, easy construction, economic and practical outstanding characteristics. Plastic sprayed blade barbed rope is a surface treatment method of spraying plastic powder on blade barbed rope in process.
- Of course, the quality of any kind of product is also affected by the implementation of the specification of the manufacturer, if it is the welding screen manufacturers in the production of their own is not very high implementation of the specification, or in the production line of the procedure specification has declined, or there is no higher requirements on the production link.
The production process of large rolls of galvanized wire is a level of drawing, through the mold into a slightly smaller diameter than the original. And so on down to the desired length. One pull is not desirable, must be numbered, from coarse to fine is dependent on metal ductility. If it changes too much it just breaks. After drawing to a certain diameter, galvanized, so that the finished product.
3. Quality test report
To remove surface active substances by matting with activated carbon. Or filtration to make the foam less stable, which are effective measures; Other measures should also be taken to reduce the amount of surface-active substances brought in to Z. The electroplating speed can be significantly reduced by the introduction of organic matter. Although the chemical formula is conducive to a high deposition rate, the coating thickness cannot meet the requirements after the organic matter is loaded, so activated carbon can be used to treat the tank.
- According to the habit often according to the basic galvanized hardware before plating treatment method, as long as it does not contact with water can keep 5~7 years or so without rust, of course, if it is a salt water test, it will not be over 4 hours. Hot dip zinc is to use zinc tin solution to cover the hardware, and the rust prevention time is about five times that of traditional galvanizing. The general outdoor construction is to use hot dip zinc, and the salt water test can do about 36 hours.
Post time: 11-08-22Large roll galvanized wire is simply galvanized iron wire, usually used wire is often visible, because iron is very easy to be corroded and rusted, so it is necessary to put a layer of other not easy to rust metal plating in the outer layer, to achieve the effect of corrosion resistance and rust resistance, the effect of zinc can do more. Therefore, many customers often require hardware factories to produce galvanized iron wire, which requires the use of galvanized iron wire equipment.
Post time: 18-05-22First, 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.
- 2. Breeding chickens, ducks, geese and other small animals, fruit and wood garden enclosure protection, medium breeding protection, it is recommended that you choose 2.3mm-2.5mm wire diameter products.
- Performance characteristics of zinc coating: zinc layer of thick galvanized wire zinc layer crystallinity meticulous, uniform and no gap, good corrosion resistance; The zinc layer obtained by electrogalvanizing is very pure and corrodes slowly in the gas, liquid and fog of acid and alkali, which can effectively protect the steel matrix. Galvanized layer can also be chromic acid passivation treatment into a variety of colors, beautiful and generous, with good decorative; The zinc layer on the galvanized wire has good ductility, can be cold blanking, rolling, bending and other molding without damage to the zinc layer.
In addition, heavy hexagonal net is commonly used in water conservancy projects, as the use of loading stone box, in order to achieve the purpose of river management, floods, in addition to it can also be used as slope prevention, retaining wall, breeding and cherish animals. Small hexagonal net is usually used for animal breeding, wall protection network, green vegetation network and so on.
- Through the maintenance of galvanized wire, not only can greatly prolong its service life, but also can improve its efficiency in the daily use process. The difference between galvanized wire and general iron wire is very big, general iron wire is cheap, and because iron is not very stable, easy to rust in wet places, so the stability is not very good, life is not very long. Galvanized wire A stable layer of zinc is coated on the outside of the wire, which is used to protect the wire and make the wire service life longer.
Industrial rust prevention method: coated with asphalt, iron roof, coated with asphalt, you can prevent rust. Metal coating: Some metal surface will form a dense oxide film, can be coated on the surface of the metal composed of this metal screen. Such as: galvanized iron, tinplate plating, bicycle underwire and some medical equipment are coated with chromium and nickel.
- 2, mesh, mesh also directly affects the price of the stone cage net
Enclosure to calculate the use of barbed rope, so as to reasonably plan to purchase the amount of barbed rope to facilitate construction
- Hot dip galvanizing is in the hot melt zinc liquid dip plating, production speed, thick but uneven coating, the market allows the thickness of 45 microns, up to 300 microns above. It is dark in color, consumes more zinc metal, forms infiltration layer with base metal, and has good corrosion resistance. Hot dip galvanizing can be maintained for decades in outdoor environment. The protection of zinc coating on iron matrix has two principles: on the one hand, although zinc is more active and easy to oxidize than iron, but its oxide film is not as loose and compact as iron oxide. The dense oxide layer formed on the surface inhibits the further oxidation of zinc in the interior.
Galvanized hexagonal mesh is a kind of galvanized metal wire mesh, the mesh shape is hexagonal.
- Packaging is also very important, cut wire to do a good job in the bundle with plastic film tightly packed, and then in the regular box, to fill the whole box is very full and sealed, it is best not to have a half box of conditions, if there is a half box to fill with foam and other things, so that in the transit cut wire will not receive a little damage.
Post time: 14-07-22- The common type of barbed rope is double-strand barbed rope, and the models are 2.0*2.0mm, 2.25*2.25mm, 2.7*2.25mm, and all of them are galvanized barbed rope (plastic coated barbed rope is rarely used). The barbed distance (that is, the distance between winding wires) is generally 14 cm. Here’s what these models mean:
- ② Electric galvanized shaft wire direct selling shall not be used for waist hoop compression reinforcement, usually not used for all binding.
Hot-dip galvanized wire is widely used in chemical equipment, petroleum processing, Marine exploration, metal structure, electric power transmission, shipbuilding and other industries. It has been widely used in recent years in agricultural fields such as agricultural medicine sprinkler irrigation, greenhouse and construction industry such as water and gas transmission, wire casing, scaffolding, Bridges, highway guardrail and so on.
Post time: 15-09-22Our country industry chooses the low carbon steel with good quality as raw material, and then produces the quality galvanized iron wire by drawing, galvanizing and other processes. Now the production technology of galvanized iron wire products can be divided into hot plating and electroplating two kinds of methods. No matter which one is chosen, it should be carried out in accordance with the corresponding operating specifications, so as to better ensure the production of good products. For key and important parts with tensile strength greater than 1034mpa before plating, the stress should be released at 200±10℃ for more than 1 hour and 140±10℃ before plating.
Post time: 16-05-23Razor wire, also known as razor wire and razor net, is a new type of protective net. Blade barbed wire has beautiful, economic and practical, good anti-resistance effect, convenient construction and other excellent characteristics, at present, blade barbed wire has been widely used in many countries of industrial and mining enterprises, garden apartments, border posts, military fields, prisons, detention houses, government buildings and other countries of the security facilities.
Post time: 23-02-23One: according to the color of the spray blade thorn rope, its price is higher than the ordinary blade thorn rope 2000-2200 yuan, but the price ratio of the spray blade thorn rope is much higher.
When the pet consignments need to use a special pet cage, usually domestic pet cage are not qualified. Prior to shipment, the pet must be taken to the airport for quarantine inspection. The quarantine certificate should be attached to the waybill. After confirming your flight, arrive at the airport at least 3 hours in advance, anticipate the waiting time and flight time, prepare enough water and food for pets, hot weather, poor ventilation, etc., will cause harm to pets. Those who want to take pets with public transport, must go to the animal quarantine station, with proof of immunity for the county animal quarantine certificate. Clean and disinfect the pet carrier.
The barbed rope factory will store the blade barbed rope in a suitable place when it is stored, because it understands the product characteristics.
