Galvanizing is a process of coating a metal surface with zinc in an electrochemical reaction on the metal surface to improve the corrosion resistance of the metal. Wire drawing is a process in which metal materials are drawn by mechanical methods to reduce their cross-sectional area and increase their length. So, the combination of galvanized to wire drawing two processes, what impact on the performance of the product?
- The small homogeneous particles with large denier in the tank can stabilize the foam layer, but the accumulation of too many solid particles will cause explosion. Coating with activated carbon to remove surfactant, or filtering to make the foam less stable, are effective measures. Other measures should also be taken to reduce the amount of surfactant brought in to Z. The speed of electroplating can be significantly reduced by the addition of organic matter. Although the chemical formulation is conducive to high deposition rate, but the organic matter with the coating thickness can not meet the requirements, so activated carbon can be used to treat the tank liquid.

Immersed six edge barbed wire corrosion lost the original characteristics, in the shape, color and mechanical properties and other aspects will change, resulting in equipment damage, pipeline leakage, specifically, is prone to fracture, lose the original protection function. Corrosion usually metal corrosion has three types: physical, chemical corrosion and electrochemical corrosion, and corrosion depends on the chemistry of the metal itself and the organizational structure, still have relationship with the surrounding medium, such as wet environment than dry environment is easy to rust, more less than the impurities of impurities is easy corrosion, high temperature conditions than under the condition of low temperature corrosion, etc. After understanding these, we can effectively prevent the corrosion of the six sides of the wire, prolong the service life of the product.
- Generally, galvanized wire used for welding is required to have a certain hardness. After acceptance of galvanized wire, the first thing to do is to feel the hand, and the other thing is to test on the machine. Because the average user does not have testing equipment, it is also very inconvenient to test on the machine. Use a micrometer to measure the diameter of galvanized wire evenly, and keep it about 0.02mm above and below the contract signing standard, with neat appearance, no leakage plating and no mess.

But there are some necessary precautions in the production of galvanized wire. Remove all tools and piles on the work site and equipment that hinder activities, and slowly put the wire into the cylinder during pickling to prevent acid splashing on the body. When adding acid, the acid must be slowly poured into the water. Do not pour water into the acid to prevent acid spillage and injury. Workers should wear protective glasses when working. Then in the handling of wire and other items, it is strictly prohibited to push hard.
- First of all, we need to understand that the electrical conductivity of the wire depends on its material and size, and is not affected by the surface treatment method. Whether galvanized treatment or wire drawing treatment, they are the surface of the steel wire treatment, will not change the basic physical properties of the steel wire, electrical conductivity will not be affected. Therefore, in theory, the galvanized wire drawing treatment should not have any effect on the electrical conductivity of the steel wire.
