Galvanized Chain Link Fence principle of extending
Chain Link Fence corrosion problem has been plagued by large businesses
Chain Link Fence corrosion problem has been plagued by large businesses, the reason Chain Link Fence galvanized, is because of the zinc in the corrosive environment can form on the surface resistance of the good corrosion resistance of the film, not only to protect the zinc layer itself, but also to protect the Chain Link Fence. So hot dip galvanized can extend the service life of the product, of course, life is also related to the thickness of the coating and its environment.
Hot dip galvanized Chain Link Fence in different environment, the corrosion rate of different summary also two kinds of chemical corrosion and electrochemical corrosion.
(1) chemical corrosion is a direct chemical effect that occurs when the surrounding medium occurs in the metal. For example, in dry gas and non conducting liquid medium, this is what we call chemical corrosion.
(2) electrochemical corrosion is the corrosion caused by the flow of electrons in the humid gas and the conductive liquid medium. When the air in the accumulation of water on the surface of the galvanized Chain Link Fence pits, and also in the air in the form of carbon dioxide, sulfur dioxide to dissolve in water, which formed the electrolyte, which occurred in the reaction known as electrochemical corrosion. Although all stiff, but zinc reaction will form a thicker oxide protective Chain Link Fence, so the galvanizing is the best ways to extend the service life.
