Main functions of the device:
This experimental equipment simulates corrosion tests in artificial environments and is used to compare the quality of metal materials with or without anti-corrosion protection; Suitable for rapid analysis of discontinuities, pores, and damage phenomena in organic and inorganic coatings in anti-corrosion tests. In addition, for quality control purposes, comparisons can be made between samples coated with the same coating; Salt spray testing is particularly suitable for detecting discontinuities such as small pores and other defects in certain metal, organic, anodized, and conversion coatings; of which 1. The Copper Accelerated Acetate Salt Spray Test (CASS) is suitable for testing decorative coatings of copper+nickel+chromium or nickel+chromium; It was also found to be suitable for testing aluminum anode coatings; Note: Due to various factors that affect the corrosion process, such as the formation of protective films, which vary greatly depending on the conditions encountered, there is rarely a direct relationship between salt spray resistance and resistance to other media; So the obtained test results cannot be used as a direct guide for the corrosion resistance of the tested metal material in all applicable environments. Similarly, the performance of different materials in experiments cannot serve as a direct guide for their corrosion resistance in use. |

Note: The loss of carbon dioxide in the solution during spraying may cause changes in pH value. The following methods can be used, such as heating the solution to above 35 ℃ before placing it in the testing equipment, or using fresh boiling water to prepare the solution to reduce the content of carbon dioxide in the solution, which can avoid changes in pH value. To ensure the pH value of the spray solution, acid testing or copper accelerated salt spray testing can adjust the pH value of the prepared solution to 2.8-3.0 and check whether the solution and/or solute meet the requirements Test meets and product execution standards GB/T2423.17-2008/IEC 60068-2-11-1981 Salt spray test method 2.
