Description

Technical Field

[0001] The utility model relates to the technical field of salt spray corrosion testing, in particular to a salt spray corrosion testing device for rust-proof paint. Background Art

[0002] During the production of anti-rust paint, new formulas need to be tested, each batch of product needs to be sampled and tested, and the effectiveness of the anti-rust paint on different products needs to be tested. Salt spray corrosion testing is one of the many tests for anti-rust paint. The prior art discloses a variety of smoke test devices. For example, Chinese Utility Model Patent Publication No. CN220231425U proposes a salt spray corrosion test device for anti-rust paint. This device mounts the test sample in a placement groove on a V-shaped frame. The V-shaped structure makes the sample placement more secure. The water in the water groove can improve the sealing of the entire device. By adjusting the valve opening of the pressure reducing valve, the ratio of the water tank and the hydrochloric acid solution tank to the main spray tower can be controlled. At the same time, experiments can be conducted using salt spray of different concentrations. When chemical reaction experiments are required, the spray from the acetic acid spray tower and the copper acid spray tower can be controlled by controlling the partition to allow the spray from the acetic acid spray tower and the copper acid spray tower to contact the spray from the main spray tower for reaction experiments. The overall sealing is improved and the experimental range is expanded.

[0003] However, during the actual test process, it was found that the inner wall of the transparent box cover of the smoke test device was easily covered with water droplets, which affected the staff's observation of the rust condition of the samples being tested in the box, and made it inconvenient to timely understand the anti-rust performance of the anti-rust paint.
