Abstract: Through the research method of constant acceleration, the salt spray test chamber can obtain the ability of the electrophoretic coatings of different film thicknesses, different parts, and different economic structures of the product to resist accelerated salt spray test, in order to identify and analyze these parts of us in the process of painting are more likely to lead to the occurrence of corrosion, and take the corresponding protective technical measures.
By means of continuously accelerated research methods, the salt spray tester can obtain the salt spray test resistance of electrophoretic coatings with different film thicknesses, different parts, and different economic structures, in order to identify and analyze that these parts of us are more prone to cause corrosion during the painting process and to take the corresponding protective technical measures.
When people buy a car, they are often concerned about how good it looks and the quality of the surface coating is a visual assessment of the quality of the car. With the deterioration of the global environment, people are demanding good corrosion resistance from automotive coatings. How improve the corrosion resistance of a car is one of the key issues that many car manufacturers have to face, and a salt spray tester can solve this problem.
As one of the four major processes in automotive manufacturing, paint is used primarily for corrosion protection and decoration. It is an important rust protection project for automobiles. The coating provides complete protection for the body by applying high corrosion protection coatings to improve electrophoretic penetration, increasing the film thickness of each coat, applying sealants to the welds, and spraying corrosion protection wax. However, defects or deficiencies in body construction, design, and manufacture can still result in some parts of the body being more susceptible to corrosion than others. Therefore, these areas of corrosion should be identified and analyzed during the painting process, and protection measures are taken accordingly. It is important to use these corrosion delamination issues in the design phase, i.e. in new hairstyles.
Through the research method of accelerated salt spray test, the salt spray chamber can simulate the harsh air pollution environment of the electrophoretic paint film, thus obtaining the performance of the accelerated salt spray test resistance of the electrophoretic paint film with different film thickness, different parts, and different economic structures, and managing the weak points through data analysis, naturally including the research of automotive coatings.
Salt spray test chamber, also known as a salt spray test machine, salt spray test machine, or salt spray test chamber for artificial climate environment "three prevention" (damp heat, salt spray, mold) test equipment, is the study of machinery, defense industry, light industry, electronics, instrumentation, and other industries a variety of environmental adaptability and reliability of important test equipment. Has significant advantages: corrosion environment can be controlled, environmental reproducibility; test time is significantly shortened; save a lot of manpower, financial resources, and material resources, is widely used in electronics, electrical and automotive, aviation, military equipment, hardware tools, and other products, parts, metal materials and products such as electroplating, coating salt spray corrosion test.
