[New patent introduction] A salt spray corrosion test chamber

Today, I will introduce a national invention authorized patent-a salt spray corrosion test chamber. The patent was applied for by Hefei Fengsheng Shuiqi Information Technology Co., Ltd., and the authorization was announced on December 29, 2017.

Content description

The invention relates to a test box, in particular to a salt spray corrosion test box.

Background of the invention

Salt spray corrosion is a common and most destructive atmospheric corrosion. The corrosion of metal materials by salt spray is very serious. More and more attention is paid to the improvement of the salt spray corrosion resistance of products. However, the salt spray corrosion in the prior art There are still some problems in the test box. First, although the use of a transparent box cover is now popular, due to the effect of salt spray during the experiment, the clear observation of the experiment is still limited, and it is impossible to accurately judge the progress of the experiment. The requirement of high labor intensity is high; second, the support frame is usually rectangular, and the position of the sample relative to the salt sprayer is different, which reduces the contrast of the experiment.

Summary of the invention

The purpose of the present invention is to provide a salt spray corrosion test box that can reduce the influence of salt spray on observation, improve the accuracy of the experiment, reduce the labor intensity of the experimenter, and increase the contrast of the sample.

The technical scheme of the present invention is a salt spray corrosion test box, which includes a main box body, an observation window, a transparent box cover, a salt water tank and a salt spray device. The upper end of the main box body is provided with a transparent box cover, and the main box body is provided with salt spray spray. Device, the side of the main box body is provided with a salt water tank, the upper surface of the salt water tank is provided with a control device panel, the front of the main box body is provided with a salt spray meter, the transparent box cover is provided with an observation window, and a sliding window is provided at the lower end of the observation window. , The lower surface of the transparent box cover is provided with a guide rail and a limit guide rail. The positions of the guide rail and the limit guide rail are adapted to the position of the edge of the sliding window. Sealing gaskets are arranged in both groove and groove two. One end of the sliding window away from the limit rail is connected with a pull rod, and the other end of the pull rod is provided with a handle. The salt spray device includes a ring support, a funnel, and a salt spray spray. The funnel is evenly installed on the ring support On the upper surface, the salt spray sprayer is installed at the center of the ring bracket, and the upper surface of the end of the sliding window connected with the pull rod is provided with a strip-shaped gasket. Universal wheels are provided at the bottom of the main tank and the brine tank. The annular support is arranged around the salt spray sprayer, and there can be no less than one salt spray sprayer, and no less than two layers of annular support are provided for each salt spray sprayer.

A salt spray corrosion test box, which includes a main box body, an observation window, a sliding window, a transparent box cover, a salt water tank and a salt spray device. The sliding window pushes a pull rod through a handle to slide in the guide rail. When pushed to the limit guide rail position , Due to the role of the sealing pads and strip-shaped gaskets in grooves one and two, the observation window cannot be touched by the salt spray, which provides convenience for accurate observation experiments. When the sliding window is closed at the end of the experimental observation, due to the strip seal The close contact between the pad and the sliding window can wipe off the salt mist on the upper surface of the sliding window, so that after the sliding window is closed, the observation window is still not affected by the salt spray. The support frame of the salt spray device is ring-shaped. In the process, the positions of the samples on the ring support relative to the salt sprayer are consistent, which increases the contrast between the experimental samples.

The beneficial effects of a salt spray corrosion test box in the technical scheme of the present invention are: the sliding window provided can effectively avoid the influence of salt spray on the observation window, improve the accuracy of the experiment, and reduce the labor intensity of the experimenter; The comparison between the two can provide more basis for the accurate grasp of the experimental results, reduce the number of experiments, and improve the efficiency of the experiment.
