Post time: 29-07-22- Two, cold galvanized wire production process of galvanized. Galvanizing is the core process in the production of cold galvanized wire, mainly by soaking the steel wire in a molten zinc solution to form a zinc layer on its surface.
- The strength, service life and hardness of positive and negative twisting rope are good. The tensile strength of steel wire is 1200N and that of iron wire is 350N. This service life is much longer than ordinary wire barbed rope.
- If using common galvanized barbed wire due to the influence of climate and environment, will accelerate the corrosion rate of barbed wire lower utilization rate, so use stainless steel barbed wire in coastal areas is the best choice, if it is the environment is dirty it is recommended to use stainless steel barbed wire of nickel content in the highest 316 l, so that you can extend the service life, greatly enhance the protective effect.
- Pure zinc is more stable in dry air. In moist air or water containing carbon dioxide and oxygen, the surface will generate a layer of basic zinc carbonate based thin film layer, which can delay the corrosion rate of zinc layer. Comparison of corrosion resistance of zinc coating in aqueous solution of acid, alkali and sodium chloride; It is also resistant to corrosion in atmospheres containing carbon dioxide and hydrogen sulfide and in oceanic atmospheres; In high temperature and high humidity air and contain organic acid atmosphere is small, galvanized layer is also easy to be corroded.
Post time: 20-04-23- Hot dip galvanizing is also called hot dip zinc and hot dip galvanizing: it is an effective way of metal anticorrosion, mainly used in various industries of metal structure facilities. It is to immerse the steel parts after rust removal into zinc solution melted at about 500℃, so that the surface of the steel members is attached with zinc layer, so as to play the purpose of anticorrosion.
Hexagon mesh weight calculation method is: hexagon mesh weight calculation method: wire.× wire.× base x length x width ÷2=kg base: 1/2′=2.151′=1.273/4′=1.65/8′=1.875/4′=1.091′x1/2′ : 3′=0.4 warp.× Warp.×2x length x width ÷8×3=kg
Large hexagonal net called the stone cage net. Stone cage net before delivery, must be folded into a simple surface, packed compression after delivery. Then put it into the right position to open, and then put the appropriate size of the stone into the cage, the lid tight, and then the various stone cage net and adjacent stone cage net tied up.
Each coil of steel wire shall consist of one wire. The surface of the rod shall not have cracks, folds, scars, ears, layers or inclusions. However, indentation, pits, bumps, scratches and pockmarks are allowed, and the depth or height shall not be 0.2mm. There should be no corrosion and oxidation skin on the surface of the steel wire, and oxidation color is allowed by heat treatment. The surface of the wire is allowed to have scratches not exceeding half of the allowable deviation range of the diameter, and local defects not exceeding the allowable deviation of the appropriate diameter.
Galvanized wire is processed by low carbon steel wire rod. It is made of low carbon steel, after drawing forming, pickling and rust removal, high temperature annealing, hot dip galvanizing, cooling and other processes. Electrogalvanized iron wire using low carbon steel as raw materials, after drawing, galvanized and other processes completed. It has the characteristics of galvanized layer, strong corrosion resistance, strong galvanized layer, and so on. Galvanized iron wire is widely used in construction, highway walls, Zahua, weaving and other industries.
- After the wire mesh appears black spots, you can choose the appearance of treatment to deal with this problem, such as galvanized, paint, dip plastic to deal with, after the appearance of the welding mesh surface smooth and bright, beautiful and generous.
Post time: 16-08-22- Tolerance range: radial mesh deviation range is not more than ± 4%, zonal mesh deviation range is not more than ± 3%; Solder joint tensile strength exceeds the national standard.
- Galvanized wire is coated with a layer of stable zinc on the outside of the wire, and the zinc layer is used to protect the wire and make the service life of the wire longer. In the production of galvanized wire, the wire should be pickled. Pickling is to use some acid mist or acid liquid to wash away some oxides on the surface of iron, that is, rust, and some other corrosion, to achieve the purpose of cleaning iron, so that zinc will fall off when galvanized.
- The common barbed rope produced by the manufacturer is the 14*14 type of barbed rope product. Since the warp wire used is the same as the wire diameter of the barbed rope, it is easier to calculate the length and weight. Usually each kilogram of barbed rope can reach about 10 meters of service length. The length of each kilogram of raw material is about 35 meters. Since 35 meters of raw material wire diameter can produce 10 lengths of barbed rope cost.
And high quality data and production cost and production conditions are bound, so some welding screen manufacturers did not meet the requirements of this aspect, natural in this case there is no way to improve product strength. In addition to data, and produce process, even if again good data, but the factory did not meet the requirements of production process in welding, also can form the product under the high pressure welding, so it is also a kind of strength on the decline, process conditions of different manufacturers also have very big difference, so it formed a shopping mall on the above products are differences of strength.
- Hexagonal cage has a wide range of applications, with the progress of science and technology, has been extended to the major hydraulic, civil engineering. Geotechnical engineering and other projects. In the hydraulic hexagonal cage in the river construction to close the utility, it is considered appropriate to use hexagonal cage to fill stone, fixed river, can be used to avoid river erosion brought water and soil loss. In civil engineering projects, hexagonal cage is considered appropriate and the use of similar particle size volume filling, the connection between the cage is formed into a wall, which is the stone cage mesh retaining wall.
Spray powder mainly acrylic powder, polyester powder and so on. Dipping is a kind of plastic coating process, that is, the plastic coating on the matrix, generally metal, such as: daily use of clothes hangers, pliers handles, scissors on the rubber sleeve, various handrails, etc. Plastic immersion is to heat the metal to spray plastic powder evenly on the metal to form a plastic film, or heat immersion liquid into the metal to cool it and then plastic coating on the metal surface.
Post time: 14-03-23Dogs of all ages seem to love to touch their noses with humans and other animals. In fact, dogs touch their noses as a way of socializing, just like humans shake hands and hug when they meet. But dogs don’t touch every human or every animal. They pick and choose who to touch. If they don’t like you or don’t know you at all, they won’t touch your nose. However, adult dogs will touch almost every puppy’s nose, and they will not only touch the puppy’s nose, but also smell it.
Post time: 05-06-23The main difference is carbon content. Iron has a carbon content of 2.11 percent or more, while steel has a carbon content of 2.11 percent or less. Iron-carbon alloys with carbon content of more than 2.11% are cast iron (pig iron), which are basically not malleable and cannot be drawn into wire. Secondly, the content of impurities is different, and the content of harmful impurities such as sulfur and phosphorus in steel is smaller. Wire general color key, wire color light point, white point.
Post time: 03-03-23- General birds with a more dense small cage can be. Parrots, crossbilled birds and other large, special beak type hard food birds, to use a metal cage or bird rack.
- Pressure welded steel grid plate is the steel grid plate fixed by pressure resistance welding at each intersection of bearing flat steel and transverse bar, which is called pressure welded steel grid plate. Torsion torsion square steel is generally used for cross bar of pressure welded steel grid. Although they do not belong to the same variety, but in the steel lattice plate standards and performance are still the same.
