Metal Flat Washers Carbon Stell Hot Dip galvanized With DIN7989

 

Galvanizing  also known as hot dip zinc and hot dip galvanized: is an effective way of metal corrosion, mainly used in various sectors of the metal structure facilities. Is the rust after the steel immersed in about 500 ℃ melting zinc solution, so that the steel surface attached to the zinc layer, which play the purpose of corrosion. Usually, the thickness of the galvanized layer is 5 to 15 m, and the hot-dip galvanizing layer is generally 35 m or more, even up to 200 m. Hot galvanized coverage is good, the coating is dense, no organic inclusions. It is well known that the mechanism of anti-atmospheric corrosion of zinc has mechanical protection and electrochemical protection. Under the atmospheric corrosion conditions, ZnO, Zn (OH) 2 and basic zinc carbonate protective film on the surface of zinc layer can reduce the corrosion of zinc to a certain extent. Layer protective film (also known as white rust) is damaged and will form a new film. When the zinc layer is seriously damaged, threatening the iron matrix, zinc on the substrate to produce electrochemical protection, the standard potential of zinc -0.76V, iron standard potential -0.44V, zinc and iron to form a micro-battery zinc as the anode is dissolved, iron As the cathode is protected. It is clear that the hot-dip galvanizing is superior to galvanized to the atmospheric corrosion resistance of the matrix metal iron.
