Poor pretreatment before plating; Bath temperature is too low; Poor quality of additives or too many additives and organic impurities will cause poor bonding. The quality of additives also has an effect on coating foaming. Some additives react incompletely during synthesis and continue to polymerize during long-term storage or use. The additive tends to distort the crystal lattice and cause stress, causing the coating to bubble.

Heavy hexagonal mesh is made of steel wire woven into hexagonal mesh by special machinery. This kind of mesh, after cutting and assembling, can be made into fence mesh, mountain hanging mesh, vegetation three-dimensional mesh, assembly, etc. Alias: gabion mesh, heavy hexagonal mesh, ecological mesh, wire mesh, etc.

Any application environment, users want a better the strength of the welded wire mesh, only need to improve its intensity, will make better the habit of using demand, but to be improved in the strength of this product, also need yo have a variety of conditions, will need to see factory in produce what kind of material, the strength of the product also is the material strength, But a manufacturer in the data does not fit the strength requirements, after all, there is no way to make the strength of the product progress, so this is the condition to.

3. Put zinc block into the plating aid pool regularly, so that the bivalent iron in the plating aid becomes trivalent iron, and it is an important measure to stabilize the PH value in a numerical range. At the same time, it is convenient for the filter to filter out the trivalent iron ions in the plating aid; Ferric ion is controlled between 0.3 and 1.0g/L; When hydrogen is not released in the plating aid, the zinc block is continued. It is an effective measure to reduce zinc slag, improve the fluidity of zinc liquid and reduce the thickness of zinc layer to play the role of plating aid filter.

The production process of large rolls of galvanized wire is a level of drawing, through the mold into a slightly smaller diameter than the original. And so on down to the desired length. One pull is not desirable, must be numbered, from coarse to fine is dependent on metal ductility. If it changes too much it just breaks. After drawing to a certain diameter, galvanized, so that the finished product.

In reinforced concrete structure, the crack width of cold wire drawing is smaller than that of circular steel bar or even that of hot rolled thread bar. So cold wire drawing is more popular in the construction industry. The material for cold drawing is made of steel bars and can be simply explained how it is made, that is, its production process is simple. It’s based on steel bars, which are constantly stretched evenly, stretching the bars into something very thin, like wire drawing, without plasticity.
