After passivation treatment of galvanized layer, a layer of bright old and beautiful color passivation film can be generated, which can significantly improve

In order to remove defects such as surface film layer and surface inclusion of large roll galvanized wire, it can be treated by conventional technology. The

Large roll galvanized wire is made of low carbon steel wire rod processing, is made of low carbon steel, after drawing forming, pickling rust removal, high

1. Adjust electroplating process parameters Strictly control the pH value of large roll galvanized wire bath, research shows that the size of the bath pH

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,

Large roll galvanized wire is the use of low carbon steel wire processing, after drawing forming, pickling rust removal, high temperature annealing, cooling and

Galvanized wire coating rough, passivation film is not bright, bath temperature is too high. If the cathode current density is too high, zinc content in the

The physical methods mainly include manual rust removal and mechanical rust removal, chemical rust removal is generally the use of pickling method, practical

Large roll galvanized wire is simply galvanized iron wire, usually used wire is often visible, because iron is very easy to be corroded and rusted, so it is

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,

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,

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,

Large rolls of galvanized silk play a very important role in our life. Made of low carbon steel rod processing, after drawing forming, pickling rust removal,

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,

The large roll of galvanized silk should be coated with oil, the fiber core is dipped in oil, and the grease should be able to protect the fiber core from decay

With the development of mining industry, the classification of pig iron is already very broad in our country, which can satisfy the demand of mechanical

Large roll galvanized wire is processed from low carbon steel wire rod, after drawing forming, pickling rust removal, high temperature annealing, hot dip

The characteristics of large volume galvanized wire is smooth and bright surface, but wet will affect the brightness of galvanized wire, so we must pay

The large roll of galvanized silk should be coated with oil, the fiber core is dipped in oil, and the grease should be able to protect the fiber core from decay

The formation process of hot dip galvanized layer is the process of forming iron-zinc alloy between the iron matrix and the outside pure zinc layer. The surface
