Description

Technical Field

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

[0002] Salt spray corrosion is a common and most destructive atmospheric corrosion. The main corrosive component is sodium chloride in the ocean, which mainly comes from the ocean and inland saline-alkali areas. The corrosion of metal surfaces 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. At the same time, because chloride ions contain a certain amount of water and energy, they are easily adsorbed in the gaps on the metal surface and replace the oxygen in the oxide layer, turning insoluble oxides into soluble chlorides, activating the passivated surface and causing damage to the product. At present, an artificial simulated salt spray environment condition created by salt spray detection equipment is generally used to assess the corrosion resistance of products or metal materials. The artificial simulated salt spray environment test is a test that uses a certain volume A salt spray test chamber with a large volume uses artificial methods to create a salt spray environment within its volume space to assess the salt spray corrosion resistance quality of the product. However, some samples are not thoroughly cleaned before the test, and the residues thereon will affect the results of the salt spray test. A Chinese patent discloses a "salt spray test machine" with an application number of "CN202321208782.9". The side walls, air bags and exhaust pipes of the salt spray test chamber are expanded inside the T-slot to achieve sealing, thereby avoiding the situation where the side walls and cover plates of the salt spray test machine are rubbed for a long time to form gaps, resulting in insufficient sealing, and ensuring the normal use of the salt spray test machine. However, it cannot solve the problem that some samples are not thoroughly cleaned before the test, and the residues thereon will affect the results of the salt spray test. Utility Model Content
