Description

Salt spray corrosion test device

Technical Field

The utility model relates to a salt fog test equipment technical field, in particular to salt fog corrosion test device.

Background

The environmental test is that enterprises or organizations verify the quality of raw materials, semi-finished products and finished products, determine the influence of various environmental factors on industrial products, find out corresponding protective measures, examine the service life degradation condition of the products and the adaptability of the products under the environmental conditions, and verify whether the materials and the products reach the expected quality targets in research, development, design and manufacture by using various environmental test equipment to carry out environmental simulation.

The environment simulation test equipment can carry out tests such as high temperature, low pressure, constant damp and hot, alternating damp and hot, sand dust, salt spray corrosion, gas corrosion, mould, rain, vibration and the like according to various standards or user requirements. The salt spray test is an environmental test which mainly utilizes the artificial simulated salt spray environmental conditions created by a salt spray test chamber to evaluate the corrosion resistance of products or metal materials.

The salt spray corrosion resistance quality of the product is checked by a salt spray environment in a volume space of the salt spray test box by using an artificial method. Compared with the natural environment, the concentration of the chloride in the salt fog environment can simulate the content of the salt fog in the common natural environment, and can be several times or dozens of times of the content of the salt fog, so that the corrosion speed is greatly improved, and the time for obtaining the result is greatly shortened.

The salt spray test is currently carried out in a relatively static environment. However, the actual working environment of many samples has vibration factors, and in practical application scenarios, there are few non-vibration environments, and in many areas, especially in areas along the traffic, vibration is frequent and complex, and vibration can aggravate the corrosion rate. Therefore, the tolerance level of the sample under the real environmental condition cannot be reflected by the existing salt spray test, the expected life of the sample is basically based on the empirical value, and the accuracy of the test result is reduced, so that the practical guiding significance of the test result is reduced.

Therefore, how to improve the accuracy of the test result is a problem to be solved urgently by those skilled in the art.
