Description

Technical Field

[0001] The invention relates to the technical field of atmospheric corrosion testing, and more particularly to a mortise and tenon-jointed atmospheric corrosion testing exposure rack with adjustable tilt angle. Background Art

[0002] During long-term service in the atmospheric environment, materials such as steel, concrete, and wood will inevitably be affected by corrosion, resulting in degradation of their performance and even causing serious economic losses and safety hazards. Therefore, the corrosion resistance of materials in the atmospheric environment is an important indicator of their practical engineering applications. The atmospheric environmental conditions such as temperature, humidity, rainfall, chloride ion concentration, sunshine intensity, wind speed, and wind direction in different regions are often different, and materials will show specific corrosion laws and characteristics when serving in a specific atmospheric environment. Atmospheric exposure testing is an important means of obtaining corrosion data of materials in different atmospheric environments. By analyzing corrosion data and studying its corrosion laws, a scientific basis can be provided for the durability design and operation and maintenance of materials.

[0003] At present, the existing atmospheric corrosion test exposure devices usually use welding to assemble and fix the various components, which brings great inconvenience to the transportation and disassembly of the exposure devices. In addition, the corrosion process of materials in the atmospheric environment is related to the angles of sunlight exposure and rain erosion, but the exposure angles of existing exposure devices are often fixed and cannot adapt to specimens of different types and sizes. When the test conditions change, they need to be remade, which increases the test cost.

[0004] Therefore, it is an urgent problem for technicians in this field to design an atmospheric corrosion test exposure rack with an adjustable exposure tilt angle and mortise and tenon joints to connect the components for flexible assembly and disassembly. Summary of the invention
