Cold plating is a physical treatment method, the zinc is simple and uneven, the amount of zinc is also less than in the corrosion and rust prevention and chemical disposal of hot plating; The amount of hot zinc plating is relatively thick, the surface of the disposal is flat on average, and it is not easy to fall off. A layer of alloy composed of zinc and metal has very strong oxidation ability, and there is a layer of pure zinc on the outside of this layer of alloy, which is why hot plating is thicker and stronger than cold plating. Under the condition of high degree of natural recovery, galvanized hook net can play a very good maintenance effect on the environment, it is not afraid of wind and rain, it is the battle machine in the hook net, much stronger than the dip plastic hook net.

The cost of blade thorn rope is much more troublesome than ordinary thorn rope, mainly because the raw materials and processes are more factors.

Annealing wire is widely used mainly because it has a good elasticity and flexibility, in the annealing process can be a good control of its hardness and softness, it is mainly made of iron wire, more commonly used in the construction industry tie wire use. When the wire factory is in production, the annealing wire will be processed according to the performance of the material, and its hardness will be changed according to the different demand, which can make it have more advantages, reduce the consumption of metal and reduce the cost of production.

Zinc layer thickness: hot dip galvanizing of electric welding mesh, single coating thickness is generally 0.08 ~ 0.12mm, and it is a controllable index.

Small iron wire is very useful in our life, basically a lot of things will use iron wire, and iron wire can also be made into a lot of crafts, making ordinary iron wire become more aesthetic and artistic sense. Of course, the iron wire in the process of use, there will be rust, so galvanized black iron wire in the storage process, it is necessary to master the correct method.

Hook mesh is crocheted with silk heart, its mesh is uniform, flat net surface, beautiful and generous net width, thick silk diameter, not easy to corroded long life, weaving simple, beautiful and useful. Widely used for raising chickens, ducks, geese, rabbits and zoo enclosures. Protection of mechanical equipment, highway guardrail, sports site fence, road beautification with protective net. The screen in the manufacture of a box-like container, with stone filled with the cage, can be used to maintain and support seawall, hillside, road and bridge, reservoir and other civil engineering.

Hot dip galvanizing, also known as hot dip zinc and hot dip galvanizing, is an effective way of metal corrosion prevention, mainly used in various industries of metal structure facilities. It is to immerse the steel parts after rust removal into the molten zinc liquid at about 500℃, so that the surface of the steel member is attached with zinc layer, so as to play the purpose of anticorrosion.

Hot dip galvanizing is to make the molten metal react with the iron matrix to produce an alloy layer, so that the matrix and the coating are combined. Hot dip galvanizing is to first pickling the iron and steel parts. In order to remove the iron oxide on the surface of the iron and steel parts, after pickling, it is cleaned in the tank of ammonium chloride or zinc chloride aqueous solution or mixed aqueous solution of ammonium chloride and zinc chloride, and then sent into the hot dip plating tank. Hot dip galvanizing has the advantages of uniform coating, strong adhesion and long service life.

Hot dip galvanizing is then oiled and chromed. The quality of hot-galvanized sheet produced by this method is significantly improved compared with that by wet galvanizing method. It is only valuable for small-scale production. Continuous galvanizing production line includes a series of pretreatment procedures, such as alkali degreasing, hydrochloric acid pickling, water washing, solvent coating, drying, etc., and the original plate needs to be annealed in cover furnace before entering the galvanizing line.

3, with oil cloth (oil used cloth), carefully from inside to outside, including each cage wire repeatedly grinding many times. The front of the bird cage, the door flowers, where vision is often in place, are repeatedly rubbed in order to improve the surface finish, equivalent to “grinding”. Note: door flowers, arhat lines and other structures are delicate and fragile, do not break. This process, which requires time and patience, care, is also a process of observing and appreciating the cage. Use new cloth again, according to the above process, wipe again and again. This process is equivalent to polishing. For important parts, you can use a little force, the speed can be a little faster (do not use force). Be careful to fold the cloth neatly, otherwise marks will easily form. When this process is complete, the surface finish is significantly improved.

Therefore, when zinc reaches saturation in the solid melt, the two elements of zinc and iron atoms diffuse with each other, and the zinc atoms diffused into (or infiltrated into) the iron matrix migrate in the lattice of the matrix and gradually form an alloy with iron, while the iron diffused into the molten zinc liquid forms an intermetallic compound FeZn13 with zinc and sinks into the bottom of the hot-dip galvanized pot, that is, zinc slag. When the workpiece is removed from the zinc leaching solution, the surface of the pure zinc layer is formed, which is hexagonal crystal, and its iron content is not more than 0.003%.

At present, there are two processing methods of blade stabbing rope. One is to make it into a spiral shape, and then make a clip treatment. It is not only our common spiral blade stabbing rope, but also a single spiral blade stabbing rope without clip, but even a single helix can not stretch it to a relatively straight. This is mainly because the blade barbed rope is wrapped and wound at the same time, so it can only be spiral.

Different 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.
