Wire flexibility and elongation is good, can withstand the pressure of mechanical operation, in our country’s industry has played a very important role. There are many kinds of iron wire, the most common is to give black iron wire, galvanized iron wire. The corrosion resistance of the outer coating is effectively improved, but the phenomenon of crevice corrosion will be found after long-term use.
The thorn rope belongs to the weaving industry, so it is less affected by environmental protection. The thorn rope will not be discarded in the production process, and it belongs to the weaving industry, so the situation is less affected by environmental protection.
Galvanized wire coating rough, passivation film is not bright, bath temperature is too high. If the cathode current density is too high, zinc content in the bath is too high or sodium hydroxide and DPE content is too low; Solid particles or excessive foreign metal impurities in the electroplating solution can cause such problems. Solution: If the coating of large galvanized wire is rough, there may be solid particles in the plating solution. If the roughness of the part is severe, the current density may be too high.
The most obvious gap in a short time is the cross section of this piece, hot dip galvanized barbed wire because it is the surface anti-corrosion treatment, so in the cross section of this piece will appear rust, and stainless steel barbed wire because the internal raw materials and surface raw materials are consistent, so there is no such situation.Hook mesh we usually see everywhere, in fact, hook mesh is a kind of fence, like the highway, stadium fence, road fence, etc., have hook mesh. So what are the effects and advantages of the use of hook net? Next by xiaobian to introduce us to hook the characteristics of the net.
Barbed wire was used as a barrier to livestock theft, for one thing, because the surface was covered with sharp spikes that made it very difficult to penetrate through the barbed wire. On the other hand, it is because livestock generally have the habit of running into each other, which makes livestock dare not run into each other with the barbed rope, thus saving the user’s use cost.
With the increasingly extensive use of hook mesh, the method of bridge rail is also different. The height of sidewalks or seatbelt outer railings should not be lower than 1.10 metres. The net distance between railings should not be greater than 140 mm and horizontal bar rails should not be used. The planning of the hook mesh is necessary to be safe and reliable, the bolt should be installed on the basis of the railing, its strength should meet the requirements of the standard.
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
Three points should be selected before installation, which are the highest point (lowest) and the side line on both sides. The number of thorn rope column is good. When installing, it can be installed gradually according to the hook arrangement of thorn rope column.Field fence line net is a streamlined, streamlined, beautiful, tacky, fashionable European elegance; The diversity of color selection, a variety of standard color card color choice, can meet different varieties, different needs. The field fence line network can be separated with a variety of methods, and according to the customer’s request.
Galvanized iron wire has excellent endurance and elasticity, zinc can reach 300 grams/square meter. It has the characteristics of thick galvanized layer and strong corrosion resistance. Widely used in construction, handicrafts, wire mesh, highway guardrail, commodity packaging and ordinary civilian and other categories. Secondly, galvanizing can increase the mechanical strength of the product. The wire drawing process is to draw metal materials to make their grains thinner, thereby improving the mechanical strength of the product. Galvanizing can form a layer of zinc on the surface of the product, and the zinc layer itself has a high hardness, which can provide additional support during the wire drawing process and prevent the metal material from tensile fracture during the wire drawing process. Therefore, galvanized products after wire drawing can increase their strength and stiffness, and improve their tensile strength and torsional resistance.After proper heat treatment or cold drawing hardening, high carbon steel wire has high strength and hardness, high elastic limit and fatigue limit (especially notched fatigue limit), cutting function is acceptable, but welding function and cold plastic deformation ability is poor.
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.There are many kinds of galvanized solution, which can be divided into cyanide plating solution and cyanide plating solution. Cyanide galvanizing solution has good dispersion and covering ability, coating crystallization is smooth and fine, simple operation, wide application range, has been used in production for a long time. However, because the plating solution contains highly toxic cyanide, the gas escaping in the plating process is harmful to the health of workers, and the waste water must be treated strictly before discharge.
The main raw materials of blade barbed wire are galvanized wire and galvanized sheet. Because the price of galvanized sheet is more expensive than galvanized wire, it is directly reflected in the price of blade barbed wire sales. There is also the difference in processing technology also leads to the difference in the price of the blade barbed rope. The traditional barbed rope is mechanically twisted, with relatively small labor consumption and high production efficiency. But the blade barbed rope is after the second mechanical processing in the artificial processing operations to appear. Therefore, there is a big gap between labor force and production efficiency. These factors lead to the price of the blade barbed rope is more expensive main factors.Galvanized wire coating rough, passivation film is not bright, bath temperature is too high. If the cathode current density is too high, zinc content in the bath is too high or sodium hydroxide and DPE content is too low; Electroplating solution with solid particles or excessive foreign metal impurities, will lead to such problems. Solution: If the large roll galvanized wire to the above coating is rough, there may be solid particles in the plating solution. If the roughness of the part is severe, the current density may be too high.
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.In strict accordance with the multi-pass small compression rate drawing, the total compression rate is 96.48%, reducing the scraping of zinc layer. The whole wire drawing die is made of tungsten steel die and polycrystalline die. The Angle of the working cone of the wire drawing die is 12° ~ 16°, and the length of the sizing belt is 0.15 of the diameter of the wire, so as to ensure that the deformation of the zinc layer is basically synchronous with the steel wire substrate.
The utility of the hexagonal net in the playground is very superficial, in each city to build the playground, are less than the shadow of the hexagonal net. In the stadium around the installation of hexagonal nets, not only can improve the stadium group image, but also convenient city residents to carry out a row of activities.
The tensile strength of steel wire is high and the hardness is high. In the flattening process, the longitudinal movement resistance of steel wire per unit volume increases and the elongation decreases. The steel wire unit volume will move to the lateral resistance smaller, the width of the increase. On the contrary, the wire is easy to extend lengthwise, and its width decreases. This is the production of high steel wire hardness is easy to wide, small hardness, easy to stretch out of wide reasons. If the tensile strength deviation of steel wire is large, the hardness uniformity of steel wire strip is poor, the width difference of the billet rolled into large, will seriously affect the quality of the billet.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. Pet cage is mainly used for family pet breeding and protection. Our Tianfu metal products company specializes in the production of various specifications of pet cages such as pigeon cage, dog cage, bird cage, parrot cage and so on.
The formation process of hot dip galvanized layer is between the iron matrix and the outside of the pure zinc layer, the formation of iron-zinc alloy process, the workpiece surface in hot dip plating when the formation of iron-zinc alloy layer, so that the iron and pure zinc layer is well combined. The process of large roll galvanized wire can be simply described as: when the iron workpiece is immersed in the molten zinc liquid, the first zinc and α-iron (body-centered) solid melt is formed on the interface. This is a crystal formed by the matrix metal iron dissolved with zinc atoms in the solid state. The two metal atoms are fused with each other, and the attraction between the atoms is relatively small.
In addition, when using the steel wire, it is also necessary to pay attention to protecting the surface of the steel wire. For example, if the surface of the steel wire is damaged or corroded, it may affect its electrical conductivity. Therefore, in the use of steel wire, should try to avoid steel wire with wet environment or chemical substances in order to protect its surface and electrical conductivity. Canary cage is also known as hibiscus cage, jade bird cage. Can be made of nickel-plated alloy or bamboo, for the refined round, square or rectangular (breeding cage) bird cage. The top of the cage has two kinds of flat top and dome, and the bottom of the cage is closed with a bottom circle. The circular cage is about 33 cm high and 20 cm in diameter; The square cage is 24.7 cm long, 24.7 cm wide and 33.8 cm high. The spacing of the cage is 1 cm, and the diameter is 0.2 cm. Cage bottom NEED NOT BAMBOO, MAKE IT WITH PLASTIC BOARD, bottom plate CAN move, FACILITATE PULL OUT WASH. Two perches are placed in the cage, and a food and drinking pot is placed in the cage. The cage has a board at the top of the cage to change the bird’s habit of looking up at the sky.
