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.

Traditional barbed wire is woven into wire, with the development of the economy, the rapid rise of all walks of life, the limitations of the use of traditional barbed wire gradually exposed, such as: aquaculture, to the chicken circle a cage can not be too dense, the wire can not be too thick, woven mesh wire once the mesh over the surface of the net will become soft. We also have the solutions: 1, rolling the straight wire into a wavy shape, but still not enough to feed chickens with mesh can only stretch out the chicken beak can not feed! 2, is electric welding mesh, with the current to the longitude and latitude of the wire spot welding together, mesh do more than most is not restricted.

There are many important details that need to be paid special attention to during the production of barbed rope or blade barbed rope by the barbed rope factory. If any improper, it will cause unnecessary losses.

When the zinc layer is seriously damaged and endangers the iron matrix, the zinc will produce electrochemical protection on the matrix, the standard potential of zinc is -0.76V and the standard potential of iron is -0.44V. When zinc and iron form microbatteries, the zinc will be dissolved as the anode, and the iron will be protected as the cathode. Obviously, the atmospheric corrosion resistance of hot dip galvanizing is better than that of electric galvanizing.

Domestic iron wire factory has been able to consume wire rope, radial low steel wire, umbrella steel wire, spring steel wire, bicycle saddle spring steel wire and other products. In the 1980s, hot – plated low carbon steel wire, fan net cover steel wire, carbon structure steel wire, bed steel wire and so on were also published. The elongation of wire is increased after annealing. Make the product more soft and increase the scope of application of the wire.

Many electrogalvanized wire diameter products are formed by wire drawing, wire drawing is a kind of processing technology, can make the product reach the required shape and meet the standard mechanical properties. Cold wire drawing is carried out at recrystallization temperature, hot wire drawing is carried out at crystallization temperature, warm wire drawing is drawn at higher than room temperature and lower than crystallization temperature. Cold drawing is a common drawing method.

Galvanized silk hook mesh is widely used in warehouses, east and west refrigeration, protective reinforcement, park, zoo fence, Marine fishing fence and construction site fence, machinery and equipment protection. There are two kinds of use, that is, slope protection hook net (slope protection net), coal mine hook net (mine hook net, coal mine support net, roadway support net).

The silver powder is actually a mixture of aluminum powder and polymer after painting the film, the film is brittle, easy to appear adhesion problems, and corrosion resistance is also slightly poor. Galvanizing refers to the surface of metal, alloy or other materials coated with a layer of zinc to play the role of beautiful, rust prevention and other surface treatment technology. Zinc dissolves easily in acids and also in bases, so it’s an amphoteric metal. Zinc changes little in dry air.
