Novel salt solution cyclic immersion test device

Abstract

The invention discloses a novel cyclic immersion test device for a saline solution, wherein the control cabinet is arranged on the upper portion of the main box body, and the xenon lamp controller, the humidification generating device, the saline solution soaking chamber and the hot air drying chamber are arranged in the middle of the main box body. Corner wheels are mounted at the bottom of the main box body; saline solution water tanks are arranged on the two sides of the saline solution soaking chamber; a push rod lifting device is installed at the bottom of the saline solution water tank,a sample frame upper sealing plate is installed at the top of the push rod lifting device, sample frames are installed on the two sides of the sample frame upper sealing plate, the device integrates the functions of periodic soaking testing, illumination testing, hot air drying and the like, and therefore the consistency, repeatability and reliability of test results are effectively improved. Thesample holder system adopts a novel structure, can separate an upper test space from a lower test space, better simulates a real environment, and enables test results to be consistent more accurately.And the data collection system can simultaneously acquire parameters such as conductivity, temperature and humidity, dissolved oxygen, pH value and the like.

Description

technical field [0001] The invention relates to the field of a material corrosion experiment device and a cycle immersion corrosion experiment, in particular to a novel salt solution cycle immersion test device. Background technique [0002] Corrosion and aging is a type of destructive erosion caused by chemical reactions of metallic and non-metallic materials with the surrounding environment. With the blue ocean economy, corrosion protection is a key point, but also a difficulty. This requires a salt solution immersion test device that can simulate the real corrosion environment. At present, the main equipment for simulating the corrosion test equipment of the marine environment is carried out at the test station by the sea, or one or several conventional tests are simulated in the laboratory. , but the current laboratory simulated weekly immersion test devices are all tested in a box. When simulating a dry environment, the moisture interference from the immersion water ta...

AI Technical Summary

Problems solved by technology

As we all know, the salt spray test, immersion test, weekly immersion test, and light test currently on the market are all test devices with one or more functions together, which can only collect several factors at the same time, and cannot collect multiple factors or real tests. surroundings

Disadvantages of the above equipment: only simple rain test, immersion test, light test, spray test, dry air; the sample is directly above the solution for hot air drying test, and the humidity interference between the two tests is relatively large; related components Or the key parts are not treated with anti-corrosion, just simple spraying, long service life and low price
