  • When pickling, we should pay great attention to the acid has a strong corrosion, so when adding acid, we must pour acid into water, and it is along the wall of the cylinder, not a splash down, so as not to cause splash. Remember the order of pouring acid, acid into water rather than water into acid, water into acid will cause splashing and boiling, when pouring acid must wear protective glasses, must ensure that there are no non-professional onlookers, so as not to cause some risk of splashing acid.

  • The production process of large coil galvanized wire is relatively simple. The wire after cleaning is put into electroplating solution first. Of course, the plating solution should contain zinc oxide, a direct current of steel, another zinc plate in the plating solution. The zinc is transferred to the surface of the steel as a molecule. If it shows a bright and beautiful color, the wire is coated with zinc.

  • Two is to pay attention to the storage and use of galvanized wire products, according to the actual environmental standards to choose different specifications of galvanized wire products;

  • There is no adhesion test of powder spraying or fluorocarbon spraying on packaged galvanized wire, but there are two points for reference: first, in sealed or air-free environment, non-metallic volatiles can corrode zinc coating; Second, zinc at higher than 230 degrees (c) will cause the matrix metal brittle. And powder spraying and fluorocarbon spraying are to be baked at a higher temperature and in a sealed environment, causing rapid corrosion of zinc, resulting in loose corrosion film resulting in coating adhesion decline, and even lead to (matrix) steel wire brittle situation may exist.

  • The price of galvanized iron wire performance is the key to win, galvanized wire only with good performance, in order to win the market, in order to obtain customer praise. In galvanized wire, the main function of carbon in increasing hardness, less is less easy to rust, the main function of chromium is acid and alkali resistance; Nickel’s main function is high temperature resistance, acid and alkali resistance and conductive use; The main function of iron is magnetic conductivity; The main functions of titanium are low density, high hardness and strong corrosion resistance. The main function of copper is magnetic and electrical conductivity. Different chemical components have different functions, which together form the characteristics of galvanized wire.

  • When using these two products, it is obvious that there is a gap between them. By pulling or bending the wire, it is often difficult to restore the original, for example, if the same place is repeatedly bent, it will be found that it has broken, and the cold drawing wire will not. Cold drawing wire compared with iron wire, its hardness, tensile resistance, bending ability is greatly enhanced, suitable for building materials.

  • 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.
  • Quality standard: Zinc content per square meter has reached or exceeded 122g.
  • The cleaning agent used for cleaning has no effect on the adhesion of the coating and no corrosion on the base material. Acid activation Acid activation solution should be able to remove corrosion products and oxide film from the surface of parts without excessive corrosion of the matrix. Zinc plating may be zinc plated with zincate or chloride and appropriate additives shall be used to obtain a coating that meets the requirements of this standard. After light plating, light treatment is carried out. Passivated parts requiring hydrogen removal shall be passivated after hydrogen removal. Activation with 1% H2SO4 or 1% hydrochloric acid for 5 ~ 15s prior to passivation.

  • In want to use barbed wire fence ground road at both ends of each set up a stake, and then from the two stakes, every 30m to set up a stake, until the installation of the line is full of stakes, so installed barbed wire net is a straight line.

  • In order to adapt to the living habits of different birds, ornamental cages can be roughly divided into two types of bird cages, namely cereal and insectivorous cages. Cereal bird cage with canary cage, yellow bird cage, wenbird cage, bird cage, hydrangea cage, insect-eating bird cage with thrush cage, chin cage, myna cage and so on.

  • Hardness is a commonly used property index in mechanical properties of metal materials. The iron wire factory introduces a fast and economical test method for hardness testing. However, for the hardness of metal materials, there is not a unified and clear definition including all test methods at home and abroad. In general, the hardness of a metal is often considered to be the resistance of the material to plastic deformation, scratches, wear, or cutting.

  • Galvanized

  • 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.

  • Its wire diameter specifications include: 8#-24#, with thick coating, corrosion resistance, strong coating and so on. And according to the special needs of users, according to industry standards to provide various specifications of galvanized wire. Low carbon steel wire is called galvanized iron wire after drawing and galvanized, so galvanized wire products have certain characteristics. In order to better let galvanized wire play an effect, in the process of galvanized wire, generally according to customer needs to control the thickness of galvanized wire zinc layer, so that galvanized wire can meet the needs of customers.

  • 3, reduce the bivalent iron ion in the plating aid used for hot plating wire, reduce the formation of zinc slag
  • Cages are more often used for large dogs, which have a lot of strength. The crate must be strong, or the dog will easily break out of the crate.

  • Stainless steel blade barbed rope under normal circumstances, basically 20 or 30 years is no problem, but because of the problem of its own material will appear a certain degree of rust, this is also because usually stainless steel blade barbed rope used by the material is 304 material, in daily use if in a long-term humid environment will cause certain corrosion. But usually users buy stainless steel blade barbed rope is basically life will not have problems users can also rest assured to use.

  • ③ The galvanized iron wire shall not be damaged when it is tightened.
  • In the production of its own, to avoid injury, wearing the corresponding work clothes is very necessary, so that not only can avoid the occurrence of accidents, but also can better realize the production and processing of products. The application of black iron wire in the process is mainly through the hot metal billet rolled into a six-and-a-half-millimeter wire, and then put it into the drawing device to draw into different diameter of the wire, gradually reduce the aperture of the drawing disk, cooling and annealing, coating and other processes to make a variety of different specifications of the wire.

  • Cold galvanizing (galvanizing) is in the plating tank after the current unidirectional, so that the zinc gradually plated on the metal surface, slow production speed, uniform coating, thin thickness, usually as long as 3-15g, bright appearance, poor corrosion resistance, usually a few months will rust. Compared with hot dip galvanizing, the production cost of electric galvanizing is lower.

  • 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:
  • Packaging and binding electric galvanized wire is in the state of liquid zinc, after messy physical and chemical effects, not only on the steel plating thicker pure zinc layer, and also generate a zinc – iron alloy layer. This plating method not only has the corrosion resistance characteristics of galvanized wire, but also has a zinc-iron alloy layer. It also has strong corrosion resistance that can not be compared with galvanizing. Therefore, this plating method is especially suitable for all kinds of strong acid, alkali fog and other strong corrosion environment.

  • 1. Put the cat carefully in the special basin for washing the cat. Keep your cat as calm as possible.

  • After electric galvanizing hot galvanizing. Electroplated copper and other common applications of screen consumption. The weaving of the binding of the building steel wire mesh has the first braided after plating, plating after weaving and other methods, after the disposal of the wire mesh or wire mesh has good corrosion, oxidation resistance characteristics, can be used in the construction, petroleum, chemical, aquaculture, garden protection, food processing and other industries of reinforcement, protection and insulation.
