Usually, there are three kinds of metal corrosion: physical corrosion, chemical corrosion, electrochemical corrosion, corrosion in addition to the chemical properties and organizational structure of the metal itself, but also related to the surrounding medium, such as wet environment is easier to rust than dry environment, more impurities than impurities less easy corrosion, high temperature conditions than low temperature conditions easy corrosion. After understanding these, we can effectively prevent the customized corrosion of hexagonal guardrail and extend the service life of the product.
Now large roll galvanized wire in our life the use of more and more, to galvanized wire products bring a great market, galvanized wire products are more and more types. The surface coating of good quality galvanized wire is continuous and smooth. When the plating parts are installed and combined, there can be no flow hanging, slag or drop remaining, and no surface defects such as iron exposure. Good quality galvanized wire, coating must be uniform, roughly uniform in copper sulfate solution soaking five times without exposing iron. And with hammering test does not bulge, do not fall off. This is a good galvanized wire should have characteristics.
- It is generally believed that the positive and negative twisting wire wire is not as durable as the thickness, common sense thinks so, but the positive and negative twisting wire wire is used in hot galvanized steel wire, which is more than 3 times the tensile strength of the iron wire, and the zinc amount is not lower than the hot plated wire
The formation process of hot dip galvanized layer is between the iron matrix and the outside of the pure zinc layer, the formation of iron-zinc alloy process, the workpiece surface in hot dip plating when the formation of iron-zinc alloy layer, so that the iron and pure zinc layer is well combined. The process of large roll galvanized wire can be simply described as: when the iron workpiece is immersed in the molten zinc liquid, the first zinc and α-iron (body-centered) solid melt is formed on the interface. This is a crystal formed by the matrix metal iron dissolved with zinc atoms in the solid state. The two metal atoms are fused with each other, and the attraction between the atoms is relatively small.
- Galvanized hexagonal mesh uses: building wall fixed, heat preservation, heat insulation; Power plant piping, boiler heating; Anti-freezing, residential protection, landscaping protection; Raise chicken and duck, isolate chicken and duck house, play the role of protecting poultry; Protect and support seawalls, hillsides, roads and Bridges and other waterworks.
The price of galvanized iron wire is relatively low, but the corrosion resistance is excellent, so it is favored by many screen businesses. In the production process of galvanized iron wire, first of all, we should check the equipment to see if there are any problems, and then we should look at the galvanized process, whether there are factors that cause product discoloration. If these problems do not exist, or some of them occur on the same equipment, and some are normal, then we should consider the problem of raw materials at this time.
- Steel mesh benefits: Compared with traditional handmade steel mesh, steel mesh has better elasticity and even spacing. When pouring concrete, the steel mesh is not easy to bend, and the thickness of concrete protective layer is easy to control and even. In bridge deck surfacing, measure the protective layer of steel mesh. The pass rate is 95 percent.
Cattle net in outdoor use for a long time will inevitably show rust corrosion, this time the use of cattle net life depends on the maintenance of the product is not in place, we all know cattle net if a long time exposure to the harsh environment, the service life will be greatly reduced. How long does a normal cattle net last?
- Hook net use value is still very high, has a very good sex, and its manufacturing concise generous, beautiful, not in high temperature will fade, you can save a sum of maintenance costs, but also according to the different needs of the site to change the shape, to meet the needs of the site.
What kind of wire mesh fence should be used for chickens, ducks, geese and other light poultry? The so-called good refers to the high cost performance, that is, the use effect can be achieved, such as the size of the mesh, the size, etc., and the cost can be reduced to the greatest extent.
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.
- 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.
The entire steel surface is protected, and the melted zinc is easily coated evenly, whether in the interior of the pipe fitting in a depression, or in any other corner where the coating is difficult to access. The hardness of galvanized coating is greater than that of steel. The Eta layer of the upper layer of Z is only 70 DPN hardness, so it is easy to be dented by collisions. However, the hardness values of the lower layer of Zeta layer and delta layer are 179 and 211 DPN respectively, which are higher than that of the iron material of 159 DPN. Therefore, its impact resistance and wear resistance are quite good.
Small and medium-sized cat cage, dog cage and fence are mostly pure wire welding, wire diameter is generally between 2-5mm. Of course, the larger the cage, the thicker the wire, because the larger cage has to withstand more force.
Twist flower hexagonal network customized quotation needs to provide the following parameters:
Post time: 14-09-22- 3, PVC plastic coated barbed rope protection function is very good
- The last is the size of the barbed rope or blade barbed rope. The commonly used size is good, especially for some special-shaped products, which need to be mentioned repeatedly in the production process of the barbed rope factory to avoid unnecessary losses.
- The most obvious gap in a short time is the cross section. Because the hot-dip galvanized barbed rope is surface anticorrosive treatment, there will be rust in the cross section, while the stainless steel barbed rope because the internal raw materials are consistent with the surface raw materials, so there is no such situation.
- Galvanized wire to galvanized uniform, a body is now its cross section, the second is the longitudinal uniformity. In the actual operation process, such as the jitter of steel wire, the surface of the pot scum and other reasons will cause galvanized wire surface galvanized layer accumulation, should try to solve the problem.
