Hot galvanizing equipment after pickling can greatly reduce the processing time of equipment

Today we are going to show you how to control the processing time of hot-dip galvanizing equipment, how to pickling the equipment and how to control the processing time of hot-dip galvanizing equipment.

Acid washing is an important part of galvanizing for hot-dip galvanizing equipment. How to remove the rust on the surface of steel and how to improve the efficiency of galvanizing. Pickling plays a crucial role. Here's a look at the chemical reactions that occur in galvanizing equipment during pickling.

Iron oxide (FeO), ferric oxide (Fe2O3), ferric oxide (Fe3O4), and iron hydroxide (Fe (OH)) are frequently found on the surface of iron and steel. These elements must be removed thoroughly before leaching AIDS.

Iron oxide produced particularly prone to chemical dissolution reaction with acid 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.

It can be seen from this that, after special chemical reaction, the hot-dip galvanizing equipment carried out perfect pickling galvanizing on iron and steel, after hot-dip galvanizing equipment carried out pickling can greatly increase and improve the efficiency of galvanizing.
