1 1 2 concrete nailsDifferent from the general zinc barbed rope, high zinc barbed rope surface zinc content is very high can reach the former 6-8 times, so in the service life also has a great advantage, ordinary products three or five years began to corrosion and the latter will take longer to change. Stainless steel barbed rope is in the material aspect of protection, so the durability is also better, these two products are long in the service life, but in the price is high.

1 1 2 concrete nailsZinc dipping time should be adjusted according to the thickness of wire diameter. The method of adjustment is to use the lead screw above the zinc pot, the length of the distance to the ceramic sinking roller. Thick wire diameter zinc dipping time should be long, fine wire diameter zinc dipping time should be short, zinc dipping length is in the range of 2~3.5m, which is also to reduce the zinc consumption of steel wire, is an aspect of maintaining the uniformity of zinc layer.

1 1 2 concrete nailsAs we all know, even if it is the same kind of steel wire, because of the steel making process, wire drawing process and equipment are not the same, so the quality of steel wire production is not the same. Due to the different mechanical properties of steel wire itself, flattening process and equipment, the width and elongation of steel wire in the flattening process have different effects. Therefore, in the selection of wire diameter, the following three factors should be considered:

1 1 2 concrete nailsThe common weight standard of galvanized barbed rope is 25kg per coil, and the length of each coil varies from 220-250 meters according to the specifications of the barbed rope. And of course we all know that the heavier the disc the longer it is. But there is one point that is worth our attention, that is, the hollow inside the general larger disk is relatively small, and the hollow inside the lighter galvanized thorn rope is relatively large. The purpose of this is to reduce the number of bending of the thorn rope and make it easier and more beautiful when installing, on the other hand, it looks larger in appearance.

The application of electric welding net is more widely, at present it has replaced the use of other parts of the wire mesh, the cost of electric welding net is lower, the production speed is very fast, so it is very popular. Welding net galvanized before the need for processing is recrystallization annealing, because the welding net must maintain a no oxide and no other impurities of pure iron active surface, if you can not keep its surface clean will lead to a bad galvanizing effect, galvanized layer and iron material is not closely combined, so this step is necessary.
- All can do spring can be called spring steel wire, and high carbon is the highest carbon content. Features: WITH high strength and hardness, high elastic limit and fatigue limit (especially notched fatigue limit), cutting function is OK, but welding function and cold plastic deformation ability is poor.
On the contrary, the denser the ion deposition, the better the quality of zinc layer. Under the condition that the surface zinc layer is dense and bright, the quality of zinc layer per unit area should reach 80g/m2, and the process parameters should be optimized as follows: current density is 16-20A /dm2, mass concentration of zinc sulfate solution is 500g/L, and pH value is 2.5-3.0.
- Under normal circumstances, the organic matter contained in galvanized wire can make electroplating speed significantly reduced. Although chemical formulations facilitate high deposition rates, the deposition of organic matter does not meet the requirements of coating thickness, so activated carbon can be used to treat the bath.

In moist air, a dense basic zinc carbonate film forms on the surface of zinc. Zinc coating belongs to the anodic coating, it is mainly used to prevent the corrosion of steel, its protective performance and the thickness of the coating is very important. The protective and decorative properties of zinc coating can be improved significantly after passivation treatment, dyeing or coating with light protection agent.

National standards on the use of wire mesh standards have certain requirements, diameter and mesh size matching use, rather than simply diameter, on the plaster layer to use the mesh should not be greater than 20×20, diameter is not easy to be less than 1mm, just choose diameter is not much meaning, choose 40×40×0.9 and choose 10×10×0.6 wire mesh, Which is better? I’m afraid it’s 10 by 10 by 0.6.
