[0002] Silane, as a surface treatment agent, is used to enhance the adhesion performance and corrosion resistance of electrophoretic paint to the substrate. Silane can chemically react with the surface of the substrate to form a silane film bonded by chemical bonds. This silane film can provide an attachment basis for electrophoretic paint particles and increase the bonding strength between the coating and the substrate. The compatibility of silane and electrophoretic paint is also affected by some factors, such as the chemical composition of silane, the formulation of electrophoretic paint, and the coating process, etc. Therefore, it is necessary to conduct compatibility tests to evaluate the compatibility and comprehensive performance of silane and electrophoretic paint.
[0003] When testing the compatibility of silane and electrophoretic paint by using the salt spray test method, the silane and electrophoretic paint samples are exposed to a salt spray environment to simulate corrosive conditions. Observe whether phenomena such as rust spots, corrosion, or peeling occur on the coating to evaluate its corrosion resistance. Since the traditional salt spray test device needs to separately customize a placement rack for the silane and electrophoretic paint plates and fix them to obtain more accurate values, it is necessary to separately set up a fixing rack for silane and electrophoretic paint plates of different sizes and shapes, which is rather inconvenient.

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0038] Referring to Figure 1 and Figure 2 , an embodiment provided by the present invention: a compatibility test device for silane and electrophoretic paint, including a box body 1, a baffle 2 is fixedly connected to the top of the box body 1, a protective cover 3 is rotatably connected to one side of the baffle 2, a nozzle 4 is fixedly connected to the inside of the box body 1, a fixing frame 5 is fixedly connected to the top of the box body 1, a first limiting block 7 is fixedly connected to the inside of the fixing frame 5, a limiting plate 8 is slidably connected to the inside of the fixing frame 5, a first limiting groove 10 is opened in the limiting plate 8, a clamping block 9 is fixedly connected to one end of the limiting plate 8, a reset assembly is arranged inside the fixing frame 5, a sliding groove 6 is opened in the fixing frame 5, the outer wall of the clamping block 9 is slidably connected to the inside of the fixing frame 5, and the limiting plate 8 is slidably connected to the outer wall of the first limiting block 7 through the first limiting groove 10. The reset assembly includes a spring 11, one end of the spring 11 is fixedly connected to the other end of the limiting plate 8, and the other end of the spring 11 is fixedly connected to the inside of the fixing frame 5;
[0039] Specifically, first, the experimenter opens the protective cover 3. This step is to ensure the tightness of the experimental environment and prevent external factors from interfering with the experimental results. The protective cover 3 is made of high-quality materials, which can effectively isolate the external environment and ensure the accuracy and reliability of the experiment. Next, the experimenter inserts the silane and electrophoretic paint plate to be tested into the inside of the fixing frame 5 through the sliding groove 6. The fixing frame 5 is ingeniously designed, and a clamping block 9 is arranged inside, which can firmly fix the silane and electrophoretic paint plate to ensure that they will not move or shake during the experiment. The clamping block 9 is limited by sliding on the outer wall of the first limiting block 7 through the first limiting groove 10 on the limiting plate 8. This design enables the position of the clamping block 9 to be precisely adjusted, thereby ensuring that the silane and electrophoretic paint plate are firmly fixed. At the same time, the tension of the spring 11 also provides additional support for the clamping block 9, making the fixation more stable and reliable. After the silane and electrophoretic paint plate are stably installed on the fixing frame 5, the experimenter will set a saline solution in the box body 1. This step is to simulate the corrosion conditions in harsh environments such as the ocean to test the corrosion resistance of the silane and electrophoretic paint plate. The saline solution is sprayed out through the nozzle 4, making the closed environment formed by the baffle 2 and the protective cover 3 filled with salt mist. In such an environment, the silane and electrophoretic paint plate will face a severe corrosion challenge, and the experimenter will closely observe their reactions to evaluate their corrosion resistance.
[0040] Referring to Figure 3 and Figure 4, one side of the baffle 2 is fixedly connected with a connecting pipe 15, a solenoid valve 16 is fixedly connected at the connecting pipe 15, one side of the box body 1 is fixedly connected with a bracket 12, the top of the bracket 12 is fixedly connected with a filter cartridge 13, a top cover 14 is arranged at the top of the filter cartridge 13, the outer wall of the filter cartridge 13 is fixedly connected to one end of the connecting pipe 15, an exhaust fan 17 is arranged inside the filter cartridge 13, a partition 18 is fixedly connected inside the filter cartridge 13, a second limiting block 19 is fixedly connected inside the filter cartridge 13, a frame 20 is slidably connected inside the filter cartridge 13, a filter screen 22 is fixedly connected inside the frame 20, a second limiting groove 21 is formed inside the frame 20, the frame 20 is slidably connected to the outer wall of the second limiting block 19 through the second limiting groove 21, the bottom of the frame 20 is fixedly connected with a sealing ring 23, and the bottom of the sealing ring 23 is attached to the top of the partition 18;
[0041] Specifically, in the salt spray test equipment, when the test process ends, the solenoid valve 16 is opened in a timely manner, and the exhaust fan 17 starts to work, quickly sucking the salt spray accumulated inside the baffle 2 into the filter cartridge 13. The internal structure of the filter screen 22 is complex and delicate, integrating two high-efficiency materials, glass fiber and activated carbon. With its unique fiber structure, glass fiber can effectively intercept large particulate matter in the salt spray, while activated carbon, with its excellent adsorption capacity, adsorbs fine particles and harmful gases in the salt spray. The combination of these two materials makes the filter screen 22 perform excellently in salt spray filtration and adsorption, effectively ensuring the cleanliness of the discharged air. As the exhaust fan 17 continues to work, clean air is discharged, and at the same time, a certain negative pressure is formed inside the filter cartridge 13. The existence of this negative pressure causes the frame 20 to automatically fit onto the partition 18 and achieve a tight seal through the sealing ring 23. Such a design not only ensures the stability of the negative pressure inside the filter cartridge 13 but also prevents air leakage, thereby improving the efficiency of the entire filtration system. The ingenious cooperation between the second limiting groove 21 and the second limiting block 19 enables the frame 20 to always remain stable during the sliding process, and the addition of the sealing ring 23 further enhances the sealing effect, ensuring that there is no leakage during salt spray filtration.
[0042] Working principle: When using the compatibility test device for silane and electrophoretic paint, first open the protective cover 3, and then insert the silane and electrophoretic paint plate to be tested into the inside of the fixing frame 5 through the chute 6. It is fixed by the clamping block 9 inside the fixing frame 5. The clamping block 9 is limited by sliding on the outer wall of the first limiting block 7 through the first limiting groove 10 on the limiting plate 8, and is supported by the tension of the spring 11 to stably install the silane and electrophoretic paint plate on the fixing frame 5. Subsequently, a saline solution is provided inside the box body 1, and it is sprayed through the nozzle 4 to fill the closed environment formed by the baffle 2 and the protective cover 3 with salt mist for testing. When the test is completed, the solenoid valve 16 is opened, and then the exhaust fan 17 sucks the salt mist inside the baffle 2 into the inside of the filter cartridge 13 for filtration and discharge. The salt mist is filtered and adsorbed by the filter screen 22 inside the filter cartridge 13. The inside of the filter screen 22 includes glass fiber and activated carbon to achieve efficient salt mist filtration and adsorption. Subsequently, the clean air is discharged through the exhaust fan 17. The filter screen 22 is fixed by the frame 20 and is limited by sliding on the outer wall of the second limiting block 19 through the second limiting groove 21. The frame 20 and the partition 18 are sealed by the sealing ring 23. When the exhaust fan 17 works, a negative pressure will be formed inside the filter cartridge 13. Therefore, the frame 20 will automatically fit on the partition 18 and be sealed by the sealing ring 23.
[0043] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
