          Information summary:

          Pickling is an important part of the production process of hot-dip galvanizing equipment. How to reasonably remove the oxide scale and rust on the surface of cast iron parts and how to ensure the improvement of galvanizing efficiency. Pickling has a particularly important effect. Below, everyone will give a simple explanation of the chemical reaction of hot-dip galvanizing equipment. Automatic hot-dip galvanizing production line.

          The metal oxides that often exist on the surface of steel include ferrous oxide (FeO), ferric oxide (Fe2O3), ferric oxide (Fe3O4), and iron hydroxide (Fe(OH)). Be sure to clean up completely before immersing the plating flux.

          Iron oxides are very easy to chemically react with acids and melt. Ferric oxide (Fe2O3), ferric oxide and sulfuric acid are converted into ferrous chloride and hydrogen, and hydrogen can restore ferric oxide and ferric oxide. Iron is ferrous oxide, and further reacts with sulfuric acid to transform into ferrous chloride, which is soluble in water.

          ??It is not difficult to see that after a unique chemical reaction, the hot-dip galvanizing equipment has carried out successful pickling and galvanizing of steel. The chemical reaction in the pickling of the hot-dip galvanizing equipment has shown a guarantee for the improvement of the efficiency of the hot-dip galvanizing afterwards. Automatic hot-dip galvanizing production line.

          ??1. Low solution cost: the cost of hot-dip galvanizing anti-rust treatment is lower than that of other paint coatings;

          ??2. Long-lasting durability: In the suburban natural environment, the standard hot-dip galvanizing anti-rust treatment thickness can be maintained for a long time without repair;

          ??3. Good credibility: The galvanized layer and the stainless steel sheet are combined in the metallurgical industry and become a part of the steel surface, so the resistance of the coating is relatively reliable;

          ??4. The coating has strong ductility: the galvanized layer produces a very metallurgical industrial structure, which can bear the damage of mechanical equipment during transportation and application;

          ??5. Overall maintenance: each part of the plated parts can be inlaid with zinc, even in the recesses, bevels and hidden places can be maintained in multiple directions;

          ??6. Cost saving: The whole process of galvanizing is more convenient than other coating engineering construction methods, and it can prevent the time required for brushing on the construction site after installation. Automatic hot-dip galvanizing production line.
