Description

Technical Field

[0001] The present invention relates to the technical field of steel plate detection, in particular to a corrosion resistance detection device for heat-insulating color steel plates which is convenient for comparative testing. Background Art

[0002] In the fields of construction, industrial plants, etc., thermal insulation color steel plates have been widely used due to their good thermal insulation properties and light weight and high strength. With the continuous development of materials science, various emerging materials have been used in the manufacture of thermal insulation color steel plates. These emerging materials are intended to further improve the performance of thermal insulation color steel plates, such as improving thermal insulation effects and enhancing structural strength. However, no matter what emerging materials are used, thermal insulation color steel plates will inevitably face the influence of various corrosive environments during actual use, such as acidic or alkaline gases emitted in industrial production, high humidity and salt-rich air in coastal areas, etc. Therefore, after the thermal insulation color steel plates made of emerging materials are manufactured, they must be subjected to corrosion resistance testing to determine whether the thermal insulation color steel plates made of the material meet the actual use requirements and ensure that they can maintain structural integrity and stable performance during their service life.

[0003] However, there are still some shortcomings in the design of the current thermal insulation color steel plate corrosion resistance detection device: First, such devices can only detect a single corrosive gas at a time. This single detection mode results in severely low detection efficiency. In order to comprehensively evaluate the tolerance of thermal insulation color steel plates to multiple corrosive gases, more detection operations are required, which greatly prolongs the detection cycle and increases the time cost of detection.

[0004] Secondly, during the production, transportation and storage process, dust, oil and other impurities are easily attached to the outer surface of the thermal insulation color steel plate. After these impurities adhere to the surface of the thermal insulation color steel plate, they may form a protective film, which interferes with the normal contact and reaction process between the corrosive medium and the surface of the thermal insulation color steel plate, and thus has a negative impact on the accuracy of the corrosion resistance test results, resulting in the test data being unable to truly reflect the actual corrosion resistance performance of the thermal insulation color steel plate. Summary of the Invention
