3, reduce the bivalent iron ion in the plating aid used for hot plating wire, reduce the formation of zinc slag

Zinc is a silver-white metal, brittle at room temperature, soluble in acid and alkali, known as amphoteric metal. Pure zinc is more stable in dry air, and small in humid air or water containing carbon dioxide and oxygen. A thin film layer of basic zinc carbonate will be formed on the surface, which can delay the corrosion rate of zinc layer. The corrosion resistance of galvanized layer in aqueous solution of acid, alkali and sodium chloride is relatively strong. It is also not resistant to corrosion in atmospheres containing carbon dioxide and hydrogen sulfide and in Marine atmospheres; In high temperature and high humidity air and containing organic acid atmosphere is small, galvanized layer is also easy to be corroded.

The formation process of hot dip galvanized layer is between the iron matrix and the outside of the pure zinc layer, the formation of iron-zinc alloy process, the workpiece surface in hot dip plating when the formation of iron-zinc alloy layer, so that the iron and pure zinc layer is well combined. The process of large roll galvanized wire can be simply described as: when the iron workpiece is immersed in the molten zinc liquid, the first zinc and α-iron (body-centered) solid melt is formed on the interface. This is a crystal formed by the matrix metal iron dissolved with zinc atoms in the solid state. The two metal atoms are fused with each other, and the attraction between the atoms is relatively small.

The characteristics of this kind of small animal cage, is small, light, easy to carry, but also easy to clean care. For small animal cages, the wire diameter of the general iron wire is not very large, the thickness of the plastic is relatively thin, so the use of the time can not be “violent”, or the cage under the “destruction” will occur welding or plastic crack off.

Galvanized diamond net to reduce the impact of the project on the environment, protect the slope protection area of the land, maintain the rock can be fully strong, slope protection hook net through artificial planting grass planting, the implementation of green function. Suitable for any complex terrain, at the same time, does not destroy the original landform, the product is mesh distribution, visual interference, convenient for artificial afforestation, conducive to the environment, engineering and environment integration system flexibility.

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

Industrial rust prevention method: coated with asphalt, iron roof, coated with asphalt, you can prevent rust. Metal coating: Some metal surface will form a dense oxide film, can be coated on the surface of the metal composed of this metal screen. Such as: galvanized iron, tinplate plating, bicycle underwire and some medical equipment are coated with chromium and nickel.

The temperature of large roll galvanized wire should be controlled at 30 to 50℃ during electroplating. Because the chloride ions in the bath are very corrosive, quartz glass heaters are generally used. Continuous production does not need heating, but needs cooling. Cooling can be in the groove side row thin wall plastic pipe, through the flow of tap water cooling, can also be used as a titanium pipe temperature control device.

Cold wire drawing is mainly used in the production of hardened low carbon steel wire, with a diameter of 8 mm steel bar to play a fixed role in the development of the construction industry has played a role in promoting the development of the construction industry, widely used. The bonding and anchorage performance between cold wire drawing and concrete is good. When used in components, the phenomenon of cracking in the anchorage area of components and damage caused by steel wire slip is fundamentally eliminated, and the bearing capacity and anti-cracking capacity of the end of components are improved.
