Description

Alternating salt spray corrosion isolation cooling and dehumidifying device

Technical Field

The utility model relates to a salt fog corrodes technical field, specifically is an alternation salt fog corrodes isolation cooling dehydrating unit.

Background

Corrosion is the destruction or deterioration of a material or its properties under the action of the environment. Most of the corrosion occurs in the atmospheric environment, which contains corrosive elements and corrosive factors such as oxygen, humidity, temperature changes and pollutants. Salt spray corrosion is one of the common and most damaging atmospheric corrosion. The salt fog causes corrosion to the surface of the metal material because the contained chloride ions penetrate through the oxide layer and the protective layer of the metal surface to generate electrochemical reaction with the internal metal. Meanwhile, the chloride ions contain certain hydration energy, are easily extruded by pores and cracks on the metal surface and replace oxygen in an oxide layer, and insoluble oxides are changed into soluble chlorides, so that the passivated surface is changed into an active surface.

The salt spray test is an environmental test for examining the corrosion resistance of products or metal materials by mainly utilizing the artificial simulated salt spray environmental conditions created by salt spray test equipment. The method is divided into two main types, one is a natural environment exposure test, and the other is an artificial acceleration simulation salt spray environment test.

The manual salt spray environment simulation test is to utilize a test device with a certain volume space, namely a salt spray test box, to cause the salt spray environment to examine the salt spray corrosion resistance performance quality of the product by a manual method in the volume space. Compared with the natural environment, the salt concentration of the chloride in the salt spray environment can be several times or dozens of times of that in the salt spray environment of the common natural environment, so that the corrosion speed is greatly improved, and the time for obtaining the result is greatly shortened when the salt spray test is carried out on the product. If a product sample is tested in a natural exposure environment, the corrosion may take 1 year, and if the product sample is tested in a salt spray environment simulated manually, similar results can be obtained within 24 hours. Therefore, the salt spray test box is widely applied, and particularly, a salt spray alternating test method is more emphasized in recent years (the salt spray test method needs salt spray test, temperature and humidity and drying scene environments to be performed alternately), so a compressor refrigeration system is required to be additionally arranged on salt spray equipment for refrigeration and dehumidification to achieve the purposes of temperature control and humidity control.
