Compared with the traditional protective device, the advantages of barbed wire protective net are very obvious. First of all, because of the standardized production mode, the barbed wire net is dense after installation. Not conducive to the passage of personnel. The traditional way of protection due to private disorderly construction of the density of the protective net can not play a protective performance. So the installation of barbed wire net is the best choice to protect the home.
Six features of spray blade stabbing rope
The parameters to be provided are as follows:
Steel wire and iron wire have a lot of similarities, but carefully distinguish, you will find that they are not only different in the material, but also in the product characteristics are very different. So when choosing, make sure you make a clear distinction between the two. Steel wire factory introduces steel wire carbon structure steel made above, generally not galvanized, used for machinery, spring. Black and hard; Iron wire: low carbon steel (mild steel), galvanized, used for joining and wrapping. It’s white and soft.
1. Principle. Because zinc does not change easily in dry air, and in humid air, the surface can form a very dense film of zinc carbonate, which can effectively protect the interior from corrosion. And when the coating is damaged for some reason and the matrix is not too large, the zinc and steel matrix form a micro cell, so that the fastener matrix becomes the cathode and is protected. It is widely used in automobile transportation and other industries, but what is needed is the trivalent chromium passivation layer, zinc nickel alloy plating closed coating, reduce the harmful and toxic layer of hexavalent chromium passivation.
With other coatings, the opposite is true. Rust builds up immediately and spreads quickly underneath the coating, causing it to peel. The depletion of zinc in the atmosphere is very slow, about 1/17 to 1/18 of the corrosion rate of steel, and is predictable. Its life span far exceeds that of any other coating. The life of the coating depends on the thickness of the coating in a particular environment. And the coating thickness is determined by the thickness of the steel, that is, the thicker the steel is easy to get thicker coating, so the thick steel part of the same steel structure must also get thicker coating, in order to ensure a longer life.
4. Keep the rinse water clean after pickling the steel wire
The barbed rope factory will store the blade barbed rope in a suitable place when it is stored, because it understands the product characteristics.
If the coating roughness is not caused by the above reasons, it may be caused by impurities in the plating solution. Can take a small amount of electroplating solution, after filtration test, then take a small amount of electroplating solution, after zinc powder treatment test, check the problem is caused by solid particles or copper, lead and other foreign metal impurities. Test them one by one and it’s not hard to find the cause of the problem. Galvanized iron wire coating foaming, binding force is not good.
Galvanized iron wire can be divided into hot-dip galvanized iron wire and cold galvanized iron wire according to different processing methods. Galvanized iron wire is more prominent in its corrosion resistance. Galvanized iron wire has good toughness and elasticity, the amount of zinc can reach 300 g/square meter, with thick galvanized layer, strong corrosion resistance and other characteristics. Galvanized iron wire products are widely used in construction, handicrafts, wire mesh preparation, the production of galvanized hook mesh, wall mesh, highway guardrail, product packaging and daily civilian and other fields.
Of course, the quality of any product is also affected by the implementation of the manufacturer’s norms. If it is the manufacturer of electric welding mesh in production, it does not have a high implementation of the norms, or the procedural norms on the production line have decreased, or there is no higher requirements on the production link.When laying steel wire mesh, according to the laying method from the middle to both sides in turn. Wall plastering engineering use wire mesh material is generally two kinds: one is electroplating, the other is hot dip galvanized. The former has low cost and a wide range of use. The cost of hot-dip galvanized material is slightly higher than that of electroplating, and the cost is high and the life is good to prevent rust. Hot dip galvanizing is in the case of heating plating. After the zinc is melted into liquid form, the base metal is immersed in it so that the zinc interpenetrates with the base metal and binds so tightly that there are no other impurities or defects left in the process.
