Salt spray test chamber detects structural differences
With the growth of the environmental testing industry, it is becoming more and more known and understood by people. Salt spray test chambers from similar manufacturers and models have different operating modes. The test results are also different. So, what are the reasons for the different test results of the salt spray test chamber
First of all the settlement of the salt spray test chamber
Second, the set temperature in the salt spray test chamber: If there is a difference in the temperature setting of the salt spray test chamber, it will undoubtedly cause a difference in the final test;
Then,
Finally, the question of the acidity and alkalinity of the water in the salt spray test chamber: standardize the installation and installation of brine After that, the PH value should be neutral (PH value between 6.5 and 7.2), but the purity of some salts may not meet the requirements, or the PH value of brine formulated under the influence of water quality is often not binn the required range, so it is required. After installing the salt water, use PH test paper to test the pH. If it is higher than this standard, add a few drops of Hcl to neutralize it; if it is below this standard, add some NaoH to neutralize it. until the pH is neutral. Once the non-neutral salt water has been used for the test, the degree of corrosion of the sample is multiplied.
