The performance characteristics of hot dip galvanized
2002/9/14 view:
Thick and dense of pure zinc layer covering the surface of steel
fasteners, it can avoid the steel substrate contact with any of the
corrosion solution, to protect steel fasteners substrate from corrosion.
In general the atmosphere, form a layer on the surface of zinc layer is
very thin and dense surface of the zno layer. So it is difficult to
dissolve in water, iron and steel fasteners for matrix plays a certain
protective effect. If zinc oxide with other components in the atmosphere
to generate insoluble zinc salt, the anti-corrosion effect is more
ideal; With zinc - alloy alloy layer, in combination with dense, oceanic
salt fog in the atmosphere and industrial atmosphere unique corrosion
resistance;Due to the combined with strong, zinc, iron miscibility,
strong resistance to wear; Because the zinc has good ductility, and its
alloy layer and steel substrate adhesion strong, hot galvanizing can be
so cold blunt, rolling, drawing, bending and forming process, does not
damage the coating; Steel structure after hot-dip zinc, equivalent to an
annealing treatment, can effectively improve the mechanical properties
of steel matrix, and eliminate the stress of the steel forming during
welding, is beneficial to turning processing for structural steelwork;
After the hot dipping zinc fastener surface brightness is beautiful;
Pure zinc layer is one of the most rich plastic in hot-dip zinc
galvanized layer, basic close to the nature of pure zinc, has the good
ductility.
