  • In the atmosphere containing carbon dioxide and hydrogen sulfide and Marine atmosphere is not corrosion resistant, in high temperature and high humidity air and contain organic acid atmosphere is small, galvanized layer is also easy to be corroded. In order to make large rolls of galvanized wire on the surface of the deposited layer to the local, remove the surface film layer, surface inclusions and other defects can be found and treated by conventional techniques. Excess foam is caused by soaps and surfactant saponable fats brought into the tank, and moderate rates of foam formation may be harmless.

  • Therefore, when zinc reaches saturation in the solid melt, the two elements of zinc and iron atoms diffuse with each other, and the zinc atoms diffused into (or infiltrated into) the iron matrix migrate in the lattice of the matrix and gradually form an alloy with iron, while the iron diffused into the molten zinc liquid forms an intermetallic compound FeZn13 with zinc and sinks into the bottom of the hot-dip galvanized pot, that is, zinc slag. When the workpiece is removed from the zinc leaching solution, the surface of the pure zinc layer is formed, which is hexagonal crystal, and its iron content is not more than 0.003%.

  • The use of electric welding mesh is very widely, but also used in different industries, different places, many times the name is named because of the use or use, so the use of electric welding mesh is doomed to a variety of different names. Can be called row welding mesh, or zinc plating welding mesh or galvanized welding mesh. There’s also the outer wall wire, which is just used for insulation, usually placed on the outside of the wall, to reduce heat emission.

  • 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. Zinc is a silver-white metal, brittle at room temperature, soluble in acid and alkali, known as amphoteric metal. Pure zinc is more stable in dry air. In humid air or small water containing carbon dioxide and oxygen, the surface of large rolls of galvanized wire will generate a layer of basic zinc carbonate based thin film layer, which can delay the corrosion rate of zinc layer.

  • No less than 5 disks should be extracted from each inspection lot for diameter error inspection. 1 point of steel wire should be extracted from each disk to measure steel wire diameter, and the actual diameter of steel wire at this point should be taken as the average value of the two vertical directions. The diameter error of cold-drawn low carbon steel wire should conform to the rules in the table below. The unqualified inspection batches shall be checked one by one, and the qualified batches can be used for engineering.

  • For the specification of galvanized wire, the galvanized wire produced by our factory can range from No.8 to No.22, which refers to the BWG standard, that is, from about 4mm to 0.7mm, which can basically cover the type required by the customer. As for the raw material of galvanized wire, normally, we use Q195 mild steel, and some factories will also use SAE1006 or SAE1008. The following is the zinc coating, for galvanized wire, this is very important, the general zinc coating is about 50g/m2 to 80g/m2, some customers need high zinc galvanized wire, zinc coating can reach 200g/m2 to 360g/m2. The tensile strength of galvanized wire is usually 350n/m2 to 800n/m2. Then there is the packaging specification of galvanized wire. The specifications of small rolls of galvanized wire are 50kg/ roll, 100kg/ roll and 200kg/ roll. Of course, there are large rolls of galvanized wire, the weight can reach 300kg/ roll or 800kg/ roll.

  • 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.

  • Since nose touching is an important part of a dog’s social behavior, humans can use this to train them. Experts say that if owners touch their dogs’ noses regularly when they are young, they will have softer personalities and be less likely to hurt.

  • 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.

  • Fruit green and grass green plastic-coated barbed rope can be said to be the special purpose of the highway, the rest of the use is relatively small.

  • Unless the stainless steel blade barbed rope is specially customized, it is usually produced by the mould with the knife length of 22mm, which is the BTO-22 type we usually call. This is not necessarily the specification from 11mm to 65mm are specifications. Unless the customer insists on customized length requirements, the barbed rope manufacturer will produce BTO-22 stainless steel blade barbed rope.

  • The height of the shield should not be less than two meters. The length of the shield should be the width of the journey and the extension 10 meters away. The vertical load of the handrail on the bridge is 1.2KM/m, and the horizontal external load is 2.5KM/m, both of which should be calculated separately. Galvanized hook mesh belongs to a hook mesh, it is the selection of galvanized wire, hot-dip galvanized wire as raw materials, woven through the hook mesh truncated.

  • The most obvious gap in a short period of time is the cross section of this piece, hot dip galvanized wire because it is surface anti-corrosion treatment, so in the cross section of this piece will appear rust, and stainless steel wire because the internal raw materials and surface raw materials are consistent, so there is no such situation.

  • Now most people want to choose a few when choosing barbed wire material better thorn rope, but the special barbed wire the better, not right, it is important to choose which model is most suited to their own thorn rope,, although is very simple product, but in the use of these products are for specific situation is different, and has a different effect, Maybe now consumers do not have too much concept of blade barbed rope, in fact, such barbed rope products have a higher safety factor. In addition, there are also more and more barbed rope, dazzling reasons, here is an example to illustrate the choice of special barbed rope.

  • The cooling circulation system uses spray to cool the drawing die, and takes away a lot of heat generated by the drawing machine in high speed drawing in time to ensure the quality of the wire.
