Centrifugal Fan Surface Anti-corrosion Measures by Xianrun Blower

A basic thinking of corrosion control is to isolate from corrosion environment.                       In centrifugal fan, generally using surface anti-corrosion measures, such as galvanization, chromium plating, electroless plating, coating epoxy resin, etc, these measures are effective in many environments.

But for the rotating parts, please pay attention to an important phenomenon: the basis material and plating are two kinds material, with different coefficient of linear expansion; 
the rotating parts will have different deformation during the rotating elastic deformation, resulting in large amount of micro crack; If the phenomenon exist, which will accelerate the corrosion of centrifugal fan impeller. So surface anti-corrosion measures for rotating parts need careful attention.
