n-: Microsoft Yahei, r, Song Dynasty, nr; ; n-: ;"> is an artificial simulated salt mainly created by salt spray test equipment Environmental tests to evaluate the corrosion resistance of products or metal materials under fog environment conditions. It is divided into two categories, one is natural environment exposure test, and the other is artificial accelerated simulated salt spray environment test. The artificial simulated salt spray environment test uses a salt spray test chamber, a test equipment with a certain volume space, to use artificial methods in its volume space to create a salt spray environment to test the product's resistance

Compared with the natural environment, the salt concentration of chloride in the salt spray environment can be several or dozens of times that of the general natural environment, which greatly increases the corrosion rate. Conduct a salt spray test on the product and obtain the results. The time is also greatly shortened. For example, a product
