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.
- Packing: 25KG/ bale, plastic inside and woven outside.
- The above is how to prevent the rust of galvanized iron wire when stored and used. Of course, the choice of high-quality galvanized iron wire can also prevent the problem of zinc removal and rust of galvanized iron wire.

The welding core is the metal core of the electrode. In order to ensure the quality of the weld, there are strict regulations on the content of various metal elements in the weld core. In particular, there are strict restrictions on harmful impurities (such as sulfur and phosphorus), and the quality of the weld core metal should be better than that of the base metal. Arc welding cannot be carried out on a smooth rod without a coating. This is because the arc stability is very poor, splashing is very large, and the weld is not well formed. After long-term practice, it is gradually found that the performance of the electrode is greatly improved by coating the welding core with some mineral raw materials (i.e. electrode coating). (1) Ensure stable arc combustion, so that the welding process is normal. (2) Using the gas produced after the drug skin reaction, protect the arc and the molten pool, prevent the harmful gases in the air (such as nitrogen, oxygen, etc.) from invading the molten pool, such as these gases will cause cracks and pores in the welding material, so that the welding can not achieve the ideal effect. (3) After the drug skin is melted, slag is formed, which covers the weld surface to protect the weld metal, make the weld metal slowly cool, help the gas escape, prevent the generation of pores, and improve the structure and performance of the weld. (4) After melting, various metallurgical reactions will be carried out, such as deoxygenation, sulfur removal, phosphorus removal, etc., so as to improve weld quality and reduce alloying element burning loss.

Out-of-line annealing means that the recrystallization annealing of hot or cold rolled steel plate is carried out in the bottom type annealing furnace or cover type annealing furnace before entering the hot plating wire line, so that there is no annealing process in the galvanized line. The steel plate must maintain a clean active surface of pure iron, free of oxides and other dirt, before hot dip galvanizing. In this method, the annealed surface oxide sheet is first removed by pickling method, and then coated with a layer of zinc chloride or a mixture of ammonium chloride and zinc chloride solvent for protection, so as to prevent the plate from being oxidized again.

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.
- To walk the bird, the bird owner needs to take it out for a walk every day, not to stay in one place for a long time, in order to increase its activity.
- 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 when they grow up.
- 5, do not pull the wire beyond the plastic limit.
- Alias: gabion mesh, heavy hexagonal mesh, ecological mesh, wire mesh, etc.
- The positive and negative twisting barbed wire is less than 3 cents per meter, and the corresponding 12 hot dip galvanized barbed wire is 5 cents per meter, no matter from the service life, tensile strength, rust prevention effect is no worse than the 12 iron wire

Select cut wire first of all to ensure that the raw material of the silk is exactly the raw material you need, the raw material to ensure that it will be used well. Choose the straightness is relatively high, so that the length of the truncation will be the same, there will not be a lot of length difference, the length of the truncated wire is a very important element to select the truncated wire.
- Although to be able to reduce the cost of production, but the overall strength of the product will have a great lack, so in this case will also let it have a great strength drop. Of course, in the mall, the higher the intensity of the data in the production of the higher the implementation of norms, naturally there will be certain progress in the price.

Bird cage is a kind of pet cage, is the main environment for ornamental birds to carry out activities and habitat, “work to do a good job, must first sharpen its tools” bird equipment is applicable or not, is one of the key to raise ornamental birds. Therefore, only if the appropriate cage and other accessories are prepared first, can the birds be kept healthy and lively, singing freely and suitable for viewing. There are many kinds of cages, depending on their body shape and habits.
- Because the bundled galvanized wire is endowed with pre-tension, so it has the excellent characteristics of low relaxation value, small stress loss, good stability after loading, not easy to deformation, no fracture, strong elasticity, ordinary steel lines and rebar is difficult to match. The use of advanced galvanized finishing process, therefore, the use of hot-dip galvanized steel wire construction, not only good anti-corrosion performance, and beautiful generous. The product has the characteristics of smooth surface, high dimensional precision, good uniformity of zinc layer and firm adhesion.
- Characteristics: strong anti-corrosion performance, bright appearance, beautiful appearance.

1. The diameter of the raw material and the thickness of the diameter are directly affected;
- 3, wear gloves, take about a bottle of disinfectant cap, pour into the basin, dilute with water according to the reference ratio. Dip a small brush into the diluted disinfectant solution and scrub the cage.
- The management system of the rinsing water after wire pickling should be discharged regularly and regularly, and the rinsing water should be kept clean and low acid value as far as possible. It is more appropriate to control the pH value of 3. The concentration of plating aid should not be too high. The hot plating wire must be added with ammonium chloride and zinc chloride according to the data of laboratory analysis, and the specific gravity of the composite solution is controlled within the range of 50~80g/L. If ammonium chloride or zinc chloride is added without reference to the results of laboratory analysis, it should be criticized and educated, and economic treatment should be given if necessary.
