[0007] Preferably, the horizontal and vertical plates are evenly arranged to form a grid of the same size.

[0008] Preferably, the grid is numbered.

[0009] Preferably, an iron sheet is provided at the bottom of the grid plate.

[0015] Beneficial effects:

[0016] 1. This utility model provides a rust inhibitor testing device, which uses a magnetic plate to adsorb iron samples onto filter paper and uses a grid plate to separate the iron samples. When salt water is added to the container during testing, the iron samples will not be dispersed and will remain in place, making it easy to observe the rust condition of the iron samples.

[0023] The following detailed description of preferred embodiments of the present invention, along with the included examples, will make the content of the present invention more readily understood. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. In case of any conflict, the definitions in this specification shall prevail.

[0024] Example 1:

[0025] Provided such as Figure 1-4 The rust inhibitor testing device shown includes: a magnetic plate 1, a container 2 and a grid plate 3. The container 2 is placed on the magnetic plate 1, and filter paper 4 is placed inside the container 2. The grid plate 3 is placed on the filter paper 4 and is used to place an iron sample 5.

[0026] The grid plate 3 includes an outer plate 31, horizontal plates 32, and vertical plates 33. The horizontal plates 32 and vertical plates 33 are located within the outer plate 31, and they intersect each other to form several squares within the outer plate 31. The horizontal plates 32 and vertical plates 33 are evenly arranged to form squares of the same size. The squares are numbered. The iron sample 5 is placed within the squares, separated from each other by the grid plate 3. The squares are numbered to facilitate quick location of the iron sample 5. Optionally, the horizontal plates 32, vertical plates 33, and outer plate 31 can be integrally formed by mold casting.

[0027] A metal sheet 34 is provided at the bottom of the grid plate 3. The metal sheet 34 is attracted by the magnetic plate 1 to increase the adsorption force between the grid plate 3 and the container 2. In one optional embodiment, a groove 35 is provided on the bottom surface of the outer plate 31, and the metal sheet 34 is placed in the groove 35. Sealing rings 36 are provided on the inner and outer sides of the metal sheet 34. The sealing rings 36 are used to seal the metal sheet 34 and reduce the contact between the metal sheet 34 and the brine. The surface of the metal sheet 34 is coated with anti-rust paint to reduce the corrosion rate of the metal sheet 34.

[0028] The grid plate 3 is made of plastic. The material of the grid plate 3 can be one of PMMA, PC, PET, PS, PP, or PES. The grid plate 3 is made of transparent plastic, making it easy to observe the corrosion of the iron sample 5 inside the grid plate 3.

[0029] The material of container 2 is glass or plexiglass. Container 2 is made of transparent material, which facilitates observation of the corrosion of the iron sample 5 inside the grid 3.

[0030] Working principle: After pretreatment, iron samples 5 are divided into two groups: an experimental group and a control group. The experimental group is coated with a rust inhibitor, while the control group remains uncoated and in its original state. The two groups of iron samples 5 are numbered and placed sequentially into grid 3. A 3.5% sodium chloride aqueous solution is added, ensuring that the iron samples 5 are completely immersed in the solution. Each iron sample 5 is placed in its corresponding grid, avoiding contact with the others to prevent interference. The rust condition of the iron samples 5 is observed periodically, and the rust data is recorded to determine the rust-preventing effect of the rust inhibitor.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. These modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
