Metal & Plastic Hot Dip Galvanizing Line

We are Making, Exporting and Supplying Hot Dip Galvanizing Lines in Shijiazhuang, Hebei, China. Today general-secretary hot dip galvanizing line how to introduce the hot galvanizing equipment for pickling, hope that through this article, the basic characteristics of Solomon galvanizing equipment for everyone to have a certain knowledge and understanding.

Pickling is an important part in the production process of hot-dip galvanizing equipment. Pickling plays a vital role.

How is hot dip galvanizing equipment pickling

Often on the steel surface oxide with ferrous oxide (FeO), ferric oxide (Fe2O3) and ferroferric oxide (Fe3O4), as well as iron hydroxide (Fe (OH)), these elements must be thoroughly cleared before immersion plating aid.

Iron oxide is easy to react with acid and dissolved, ferric oxide, Fe2O3 and ferroferric oxide and hydrochloric acid reaction, ferrous chloride and hydrogen and the hydrogen can restore ferric oxide and ferroferric oxide as ferrous oxide, thus further react with hydrochloric acid to generate ferrous chloride, ferrous chloride is soluble in water.

Thus, through the special chemical reaction, hot dip galvanized equipment for steel pickling galvanization, successfully to pickling for subsequent hot dip galvanized galvanized equipment efficiency provides a guarantee.
