Description

Technical Field

[0001] The utility model relates to the technical field of salt spray test, in particular to a salt spray testing machine. Background Art

[0002] Salt spray corrosion is a common and most destructive atmospheric corrosion. Among them, the chlorides in the atmosphere have the most obvious corrosion effect on metals. Its main corrosive component is the chloride salt in the ocean - sodium chloride, which mainly comes from the ocean and inland saline-alkali areas. The corrosion of the salt spray on the surface of metal materials is caused by the chloride ions penetrating the oxide layer and protective layer on the metal surface and undergoing an electrochemical reaction with the internal metal. At the same time, the chloride ions contain a certain amount of hydration energy and are easily adsorbed in the pores and cracks on the metal surface, displacing and replacing the oxygen in the oxide layer, turning the insoluble oxide into a soluble chloride, making the passivated surface become an active surface, resulting in extremely bad adverse reactions to the product.

[0003] Most of the existing salt spray testing machines require manual material taking after the experiment, wasting manpower. Since the salt spray is concentrated above, it will lead to inaccurate experimental data. At the same time, when discharging the salt spray, it may cause air pollution, and the filter screen cannot be replaced in time. Therefore, it is necessary to design a salt spray testing machine.
