Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of rim detection, and particularly relates to a rim salt spray test box and a use method thereof. BACKGROUND

[0002] The rim is made of metal, and is prone to corrosion during long-term use, especially at the welding position. The rim corrosion environment can be simulated by using a salt spray test, so as to predict the corrosion resistance of the rim. The salt spray test mainly uses an artificial simulated salt spray environment condition created by a salt spray test device to examine the corrosion resistance of a product or a metal material. The artificial simulated salt spray environment test uses a test device, i.e., a salt spray test box, to create a salt spray environment in the volume space of the test box by using an artificial method, so as to examine the salt spray corrosion resistance of the product. Compared with a natural environment, the salt concentration of the chloride in the salt spray environment can be several or tens of times of the natural environment, so that the corrosion rate is greatly improved, and the time for obtaining the result of the salt spray test of the product is greatly shortened. For example, the product sample is tested in a natural exposure environment, and the corrosion may take one year, while the similar result can be obtained in 24 hours in the artificial simulated salt spray environment. In the existing rim salt spray test process, the rim is in a static state in the test box, and the salt spray cannot be uniformly distributed in the test box, so that a dead angle where the rim cannot contact the salt spray appears locally, especially at the welding position, the salt spray cannot fully contact the rim, and the corrosion resistance of the rim cannot be accurately reflected.
