Salt spray test

Bopen salt spray test

Salt spray test is an environmental test that mainly uses the artificial simulated salt spray environmental conditions created by salt spray test equipment to evaluate the corrosion resistance of products or metal materials. It is divided into two categories, one is natural environmental exposure test, the other is artificial accelerated simulated salt spray environmental test. Artificial simulated salt spray environment test is to use a test equipment with a certain volume space - salt spray test chamber to create a salt spray environment by artificial method in its volume space to evaluate the salt spray corrosion resistance and quality of products. Compared with the natural environment, the salt concentration of chloride in the salt spray environment can be several times or dozens of times of the salt spray content in the general natural environment, which greatly improves the corrosion speed. The time to obtain the results of salt spray test on products is also greatly shortened. If a product sample is tested in the natural exposure environment, it may take 1 year to be corroded, while similar results can be obtained in the artificial salt spray environment for only 24 hours.

We use 5% NaCl solution, the pH value of the solution is in neutral range (6.5 ~ 7.2) as a spray solution. The test temperature is 45 ℃, and the sedimentation rate of salt spray is required to be between 1 ~ 3ml / 80cm2. H, and the sedimentation is generally between 1 ~ 2ml / 80cm2. H. Test the parts of each batch to ensure the excellent weather resistance of Bopan products.
