Description

Technical Field

[0001] The utility model relates to the technical field of salt spray test, in particular to a salt spray test box with adjustable spray volume. Background Art

[0002] The fog test chamber uses salt spray corrosion to detect the corrosion resistance reliability of the tested samples. Salt spray refers to a dispersion system composed of tiny salt droplets in the atmosphere. It is one of the three-proof series of artificial environments. The salt spray test is divided into neutral salt spray and acidic salt spray. The difference lies in the different standards and test methods. They are called NSS and CASS tests respectively. They are the most common test methods in artificial three-proof climates. Salt spray corrosion is a common and most destructive atmospheric corrosion. The corrosion of metal materials by salt spray is caused by the electrochemical reaction between chloride ions penetrating the oxide layer and protective layer on the metal surface and the internal metal, which activates the passivated surface and causes damage to the product. When doing salt spray corrosion tests, the existing salt water test chambers have relatively single functions and cumbersome operations. They can only perform single salt spray corrosion tests and cannot meet the diverse detection of products. Utility Model Content
