Product Description
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.
