After annealing, the extension rate of galvanized wire is increased, making the product more soft and increasing the scope of application of galvanized wire. After electric galvanized hot galvanized, electroplated copper and other widely used screen production. Building reinforcement binding with galvanized wire mesh braided with the first after plating, plating and other methods, after treatment of galvanized wire mesh or steel wire mesh, has good corrosion resistance, oxidation resistance characteristics, can be used in construction, petroleum, chemical, aquaculture, garden protection, food processing and other industries reinforcement, protection and heat preservation.

Out-of-line annealing means that the recrystallization annealing of hot or cold rolled steel plate is carried out in the bottom type annealing furnace or cover type annealing furnace before entering the hot plating wire line, so that there is no annealing process in the galvanized line. The steel plate must maintain a clean active surface of pure iron, free of oxides and other dirt, before hot dip galvanizing. In this method, the annealed surface oxide sheet is first removed by pickling method, and then coated with a layer of zinc chloride or a mixture of ammonium chloride and zinc chloride solvent for protection, so as to prevent the plate from being oxidized again.

In order to pack and bundle galvanized wire on the surface of the deposit layer to remove the surface film, surface inclusion and other defects can be found and treated by conventional technology; Excess foam is caused by soaps and saponable fatty surfactants being brought into the tank. Moderate foam formation rates may be harmless. Small homogeneous particles of large denier present in the tank can stabilize the foam layer. To remove surface active substances by matting with activated carbon. Or filtration to make the foam less stable, which are effective measures; Other measures should also be taken to reduce the intake of surfactant. The electroplating speed can be significantly reduced by the introduction of organic matter. Although the chemical formula is conducive to a high deposition rate, the coating thickness cannot meet the requirements after the organic matter is loaded, so activated carbon can be used to treat the tank.

Pet cage is generally made of high quality iron wire, low carbon steel wire, stainless steel wire welding, its characteristics are beautiful, light, folding, easy to store. Pet cage surface treatment is generally: cold galvanizing, hot galvanizing, spraying, dipping, chrome plating, nickel plating and other methods. Pet cage is mainly used for family breeding pets and protection.

Galvanized barbed wire as a safety protection of the metal wall, the galvanized barbed wire device also need to be protected for a long time? And how to protect it? Maintenance and protection of galvanized barbed rope. First, we can start from two aspects. One is about the protection of galvanized barbed rope posts.

In the use of time do not need to carry out daily maintenance and maintenance, not only can save a lot of time, but also can reduce the cost, but also has good stability, strong corrosion resistance, greatly prolong the service life. According to the different process is divided into different kinds, can be selected according to their own needs, has good flexibility and elasticity. The main role of annealing wire is to control its degree of hardness and softness. When making annealing wire, it is made of steel wire.

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.

1, stress relief before plating where the maximum tensile strength is greater than 1034Mpa key and important parts before plating should be at 200±10℃ stress relief for more than 1 hours, carburizing or surface quenching parts should be at 140±10℃ stress relief for more than 5 hours.

Common galvanized iron wire equipment is usually used in barbecue net, barbecue net generally requires to have a long service life, with galvanized iron wire equipment to wire a layer of zinc, barbecue net is not easy to be corroded.
