Introduction of New Technology of Galvanized Drum
Jinqi barrel manufacturers have been working hard in this industry for many years. In the face of various customers and an increasingly severe market, in addition to always paying attention to the latest developments, the rest of the time is used to improve the performance of their products, and the galvanizing process Ascension is one aspect of it. German manufacturers have learned in recent years that it is impossible to survive in the market simply by producing iron drums, and all kinds of paint drums and paint drums that are popular nowadays are all galvanized.
Galvanized iron drum material: Zinc is easily soluble in acid and alkali, so it is called amphoteric metal. Galvanized iron barrels hardly change in dry air. In humid air, a dense basic zinc carbonate film will be formed on the surface of galvanized iron drums. The corrosion resistance of galvanized iron drums is poor in the atmosphere containing sulfur dioxide, hydrogen sulfide and marine.
In the atmosphere of high temperature and high humidity containing organic acid, the zinc coating of galvanized iron drum is easily corroded. The standard electrode potential of zinc in galvanized iron barrels is -0.76V. For the steel substrate, the zinc coating of galvanized iron barrels is an anodic coating, which is mainly used to prevent the corrosion of steel, and its protective performance has a great relationship with the thickness of the coating.
The above are the advantages of galvanized iron barrels, I hope to help you, of course, if you have any other questions, please call or leave a message online, we will reply as soon as possible. Next time, we will continue to discuss the selection of galvanized materials for iron drums. Of course, if you have better countermeasures and solutions, please let us know, we will be very grateful.
