The iron is clean and clean, and then solvent treatment, after drying immersed in zinc liquid, iron and molten zinc reaction to produce an alloyed zinc layer, the process is: degreasing – washing – pickling – assisted plating – drying – hot dip galvanizing – separation – cooling passivation. The thickness of the alloy layer of hot plating wire mainly depends on the chemical composition of the steel silicon content, the size of the steel cross-sectional area, the roughness of the steel surface, the temperature of the zinc pot, the time of dipping zinc, cooling speed, cold rolling deformation, etc.

Large roll galvanized wire is processed by low carbon steel wire rod, through drawing molding, pickling rust removal, high temperature annealing, cooling and other processes. Large roll galvanized wire electroplating temperature should be controlled in 30-50℃. Because of the strong corrosivity of chloride ions in bath, quartz glass heater is generally used. Continuous production does not need heating, but need cooling cooling.

Some customers are just for ordinary fencing, but the pictures provided to the barbed rope factory are indeed applied to the barbed rope products in prison, maybe because the customers prefer the style, but such products are really a little overqualified to be installed in ordinary areas. Even if the customers prefer such barbed rope products, the higher price is prohibitive. The price and quality of the prison rope are certainly not the level of the rope we contact in our daily life.

Galvanized wire is processed from low carbon steel wire rod, after drawing forming, pickling rust removal, high temperature annealing, cooling and other processes. Galvanized wire is widely used. Electroplating temperature should be controlled at 30 to 50℃. Because the chloride ions in the bath are very corrosive, quartz glass heaters are generally used.

2. The cleaning agent used for cleaning should have no effect on the binding force of the coating and no corrosion on the matrix.

3. Acid activation acid activation solution should be able to remove corrosion products and oxide film (skin) on the surface of parts, without excessive corrosion on the matrix.

The main raw materials of blade barbed wire are galvanized wire and galvanized sheet. Because the price of galvanized sheet is more expensive than galvanized wire, it is directly reflected in the price of blade barbed wire. There is also the difference in processing technology also leads to the difference in the price of the blade. The traditional barbed rope is made of mechanical wringing, which has a relatively small amount of labor and high production efficiency. However, the blade barbed rope is processed manually after secondary mechanical processing. So whether from the labor force or from the production efficiency also said that there is a large gap. These factors lead to the price of the blade barbed rope is more expensive.

Poor pretreatment before electroplating; Bath temperature is too low; Poor quality additives or excessive additives and organic impurities can cause poor bonding. The quality of the additive also has an effect on coating foaming. Some additives react incompletely during synthesis and continue to polymerize during long-term storage or use. The additive tends to distort the lattice and create stress, causing the coating to blister.

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.
