Good galvanized wire, plating thickness of 3- 4 mm, zinc adhesion should be less than 460 grams/m, that is, the average thickness of zinc layer is not less than 65 microns. When the thickness of plated parts is greater than 4 mm, the zinc adhesion should not be less than 610 g/m, that is, the average thickness of zinc layer should not be less than 86 microns. Standard galvanized wire coating must be uniform, galvanized layer basically uniform with copper sulfate solution test etching five times no dew iron. For standard galvanized wire coating adhesion requirements, the zinc layer of plated parts should be firmly combined with the basic metal and have enough adhesion strength, after hammer test does not fall off, not convex.

The wire used for barbed wire is woven or welded with low carbon steel wire, medium carbon steel wire, high carbon steel wire, stainless steel wire and other materials. The production process includes: general braid, embossed braid and spot welding. If the material is steel wire, after equipment processing into a network, it is called wire mesh.

In order to orchard special electric galvanized shaft wire in alluvial surface to partially remove the surface film layer, surface impurity and other shortcomings can be found and solved according to the basic technology; Excessive foam is caused by soap and soapable surface active substances such as human fat into the tank. A moderate rate of foam production would be fine. The large amount of fine homogeneous particles in the tank can stabilize the foam layer, but the accumulation of too much solid particles will cause explosion.

The size of the galvanized layer of galvanized iron wire is related to the anti-corrosion ability and application effect of galvanized wire. The thickness of the galvanized layer of the general standard galvanized wire products should be tested after the product is formed. There are three specific test methods. Weighing method and cross section microscopy method are destructive experimental methods, and magnetic method is a relatively rigorous non-destructive method, but the measurement steps and requirements are relatively high, so they are rarely used in specific applications. The first two methods are intuitive and common methods.

Hot wire plating adopts zinc-free slag to add hot molten zinc and galvanizing, which avoids the traditional heating process, radiates 1653 hot molten zinc on surface 4102 of zinc liquid surface, and reduces the high temperature oxidation of zinc liquid surface. At the same time, the heating body is in contact with the zinc liquid, and the heat is directly transferred to the zinc liquid. The utilization rate of heat energy can reach more than 90%, and the heat radiation on the zinc liquid surface is reduced.

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, and small in humid air or water containing carbon dioxide and oxygen. A thin film layer of basic zinc carbonate will be formed on the surface, which can delay the corrosion rate of zinc layer. The corrosion resistance of galvanized layer in aqueous solution of acid, alkali and sodium chloride is relatively strong. It is also not resistant to corrosion in atmospheres containing carbon dioxide and hydrogen sulfide and in Marine atmospheres; In high temperature and high humidity air and containing organic acid atmosphere is small, galvanized layer is also easy to be corroded.
