Dry-wet alternating ultraviolet irradiation simulation corrosion test device

Abstract

The invention provides a dry-wet alternating ultraviolet irradiation simulation corrosion test device, and belongs to the technical field of corrosion tests. The device has the prominent characteristics that the processes of rising tide and falling tide of seawater are simulated in a water circulation manner, and a small stirring device is arranged in the box. Therefore, on one hand, the flowing state of fluid in the test box can be improved by matching with water feeding and water discharging, and a real sea dynamic dry-wet alternating environment is better fitted; mass transfer and heat transfer in the test box can be improved; thirdly, in the cleaning mode, the rotation of the stirring device is beneficial to enhancing the turbulence of the fluid, so that a better cleaning effect is achieved. In addition, deionized water circulation is added in a conventional circulation system, so that the test device has a self-cleaning function, and maintenance of the device is facilitated. And finally, water for water bath heat preservation and water for cleaning are combined into a whole, the utilization of space and resources is improved, and meanwhile, heating is more uniform through water bath heating. As a result, the reasonable arrangement enables the space utilization rate in the test box to be high, and the flexible pipeline design is suitable for working under various conditions.

Description

technical field [0001] The invention belongs to the technical field of corrosion tests, and in particular relates to a dry-wet alternating corrosion aging test device for simulating materials in a marine environment under ultraviolet light conditions through dynamic water circulation. Background technique [0002] my country has a vast territory, with a total coastline of more than 32,000 kilometers, rich in marine resources, and the problem of marine corrosion has existed since ancient times. Corrosion refers to the damage or deterioration of materials or their properties under the action of the environment, which greatly reduces the service life of materials. Corrosion test is an important means to understand the characteristics of the corrosion system composed of materials and environment, to study the corrosion mechanism, and to control the corrosion process. [0003] my country has carried out corrosion protection research for nearly 70 years. Now the corrosion protect...
