Description

Technical Field

[0001] The utility model relates to the technical field of suspension equipment, in particular to a full-immersion corrosion specimen suspension device. Background Technique

[0002] At present, during the operation and maintenance stage of an aircraft, in order to achieve purposes such as disinfection and pest control, a variety of aircraft-specific chemicals such as disinfectants and insecticides are used. Some of these chemicals are corrosive to metals. Once corrosive deterioration occurs on the surface of the aircraft fuselage, it will affect the stability and safety of the aircraft. At the same time, if corrosion is not detected in time and protective and remedial measures are not taken, it will pose a hazard to the personal safety of passengers. Whether aircraft-specific chemicals can meet the airworthiness requirements usually requires a series of experiments, among which the corrosion experiment is an important link. According to the requirements in ASTM F 483 and MH / T 6059-2017 "Full-Immersion Corrosion Test Method for Chemicals Used in Aircraft Maintenance", in the full-immersion corrosion experiment, three parallel metal specimens need to be prepared for each group of experiments. At a specified temperature, these three weighed metal specimens are immersed in the test solution. When the metal specimens are immersed, it is advisable to use a glass or fluoroplastic support device to ensure that the specimens can be fully immersed and in free contact with the solution, while ensuring that the specimens can be separated from each other.

[0003] Since such a specimen support device is lacking in the market, during the experiment, it is necessary to build it by oneself with glass or fluoroplastic, which may cause insufficient contact between the specimen and the test solution or contact between the specimens, affecting the final experimental results.

[0004] Therefore, based on the above factors, there is an urgent need for a support that can be placed in a wide-mouth bottle with a stopper and can suspend 3 metal specimens at the same time to solve the above problems. Content of the Utility Model
