Galvanized Barbed Wire Anti-corrosion Method
Oct 24, 2017

Galvanized wire is made of high-quality low-carbon steel wire, galvanized iron wire is divided into hot-dip galvanized wire and cold galvanized wire (galvanized wire), is the use of high-quality low-carbon steel, drawing after forming, pickling rust, (Annealing), hot-dip galvanizing, galvanized wire mesh cooling and other processing processes.

Galvanized iron wire has good toughness and elasticity, galvanized iron wire zinc content up to 300 g / m. With a thick galvanized layer, strong corrosion resistance and so on.

1. Hot-dip galvanizing: Hot-dip galvanizing of the fruit: The solvent of the mesh surface is hot-dip galvanized by drying (ie, surface or wetting) on the surface of the molten solvent-covered zinc solution.

The drawback of this method is that it can only be galvanized in a lead-free state, the coated alloy layer is very thick and the adhesion is very poor. The dross may accumulate at the interface between the zinc solution and the lead liquid and can not be deposited at the bottom of the tank (due to the greater proportion of the scum than the weight of the zinc solution and less than the lead), the galvanized wire mesh fence is contaminated with zinc Floor. In recent years, this hot galvanized has been basically eliminated.

2. Single leaf method: First, the screen annealing to the pickling workshop, with sulfuric acid or hydrochloric acid to remove the surface of the oxygen hot galvanized iron. In the pickled fence immediately enter the tank soak waiting for galvanized after galvanized barbed wire to prevent re-oxidation of the mesh.

After pickling, the mixture is washed with water, dried and dried, poured into a zinc pot (the temperature is maintained at 445-465 ° C) hot-dip galvanized and then treated with oil and chrome. This method of producing hot galvanized steel than the wet galvanized finished product quality has been significantly improved, only small-scale fence production have a certain value.

The two galvanized methods are more ancient anti-corrosion methods, different materials for different ways, so the relative leaf method is now more popular, galvanized barbed wire mesh is more suitable for galvanized galvanized. Galvanized wire mesh is widely used in industry, agriculture, aquaculture, construction, transportation, mining and other industries. Surface formation, strong structure, integrity, with strong antioxidant corrosion, durable, easy installation, easy to fade, no deformation and so on.

Galvanized wire mesh provided by galvanized wire mesh can be used to use the mesh, can focus on the use of the value of the protection level, to strengthen the comprehensive level of network quality can reach the material may have a good protection and reasonable advantages , The use of any raw materials required for the use of the amount of reference value of the use of the value of Huangshan value of a reasonable level of the meaning of the process can better display the standard meaning of integrated components to achieve on the net surface can show galvanized iron mesh surface with anti-corrosion, High temperature, anti-aging and other comprehensive advantages, so that the program does not need to use the network long-term use of the principle of life. It is recommended that the appropriate steel pipe, galvanized barbed wire column can show that the use of numerical parameters for Yokogawa's technology to select the standard beyond the level of the surface can be included in the quality of the screen can be used to achieve the meaning of the use of Ali reasonable Plan out the quality of the bowl can be exceeded by the quality of the required use of the protective material can be achieved by the quality of the standard size of the pore size of the solid shape of the uniform treatment level level, ruggedness, aesthetics and other integrated standard skills to make the network level of quality The quality of the standard is reasonable.
