How about several ways to stop CD grain screws from rusting
With the development of technology, our CD grain screw industry, has been rapid development, but also in various fields, has been widely used, in the process of using it, there will inevitably be some quality problems, so how to stop the CD grain screw rust several methods.
1, probably dust particles multi-phase metal accessories, in the wet atmosphere, condensation water attached and iron screws, and the two connected into a microcell, resulting in electrochemical reactions, the protective film is broken, known as electrochemical decay.
2, organic juice of the iron screw profile adhesion (such as vegetables, soup, spit), oxygen in the environment of the water, the formation of organic acids, permanent organic acid corrosion of the metal surface.

Ribbed surface, adhesion includes 3 iron acid, alkali, salt materials (such as decorative walls, lime slag alkaline water splash), resulting in partial press.
4, there is air pollution (such as rich in a little hydrogen sulfide, carbon dioxide, nitrogen oxides, atmospheric) condensate, sulfuric acid, nitric acid, acetic acid solution combination of the environment, resulting in chemical corrosion.
