[0014] The above embodiments of the present invention can achieve the following beneficial effects: By setting a spray rotating structure, the spray rotating structure can drive the spray rod to move at a uniform speed inside the corrosion resistance test chamber, and can perform a steering operation at the end of the slide slot, so that the corrosive liquid can be evenly sprayed onto the surface of the test plate, and because the spray rod can be steered, the moving distance of the spray rod does not need to be consistent with the length of the test plate, so that the moving distance of the spray rod is shortened, thereby shortening the time required for the spray rod to spray the test plate, thereby increasing the time required for the corrosive liquid to be sprayed, thereby improving the working efficiency of the device; By setting up an anti-leakage structure, the anti-leakage structure can ensure that the three chutes are always in a closed state. Since the three chutes are in a sealed state, the gases generated by the blank control group and the experimental group can be prevented from interacting with each other, thereby ensuring a relatively independent test environment for the blank control group and the experimental group, making the test results more accurate and reliable, and preventing the toxic gases generated by the test from flying into the environment through the chutes, which not only greatly reduces the pollution of the device to the environment, but also prevents the physical and mental health of the testers from being eroded by harmful gases. In addition, the anti-leakage structure will not affect the normal movement and turning of the spray rod.

[0015] By setting an exhaust fan in conjunction with the gas storage chamber, the interior of the corrosion test chamber is sealed through a leak-proof structure, and the harmful gas is only inside the corrosion test chamber. Therefore, after the device test is completed, the exhaust fan can extract the harmful gas inside the corrosion test chamber, and because the interior of the corrosion test chamber is in a sealed state, the exhaust fan has a better extraction effect; By setting a reciprocating scraping structure, when the device is working, the tester observes the status of the two test plates through the two transparent observation areas. However, when the device is working, the corrosive liquid and harmful gas will adhere to the transparent observation area, making the transparent observation area blurry and unable to be accurately observed. At this time, the reciprocating scraping structure can continuously ensure that the transparent observation area is in a clear state, so that it is convenient for the tester to observe the test situation inside the device through the transparent observation area, so that during the operation of the device, the corrosion changes of the corrosion-resistant coating can be effectively recorded; Since the rotation of the rotating wheel can drive the reciprocating scraping structure to operate, that is, the spray rotating structure and the reciprocating scraping structure can operate synchronously, the linkage synergy between the different structures of the device is increased, and only one power input is required, which reduces the power output end of the device, thereby reducing the operating cost of the reciprocating scraping structure.

[0025] In this embodiment, two reciprocating scraping structures 5 are provided inside the corrosion-resistant test chamber 1, and the reciprocating scraping structures 5 include a scraping rod 41. A connecting shaft 37 is rotatably installed between the inner wall of one side of the corrosion-resistant test chamber 1 and the partition 6. One end of the connecting shaft 37 penetrates one side of the corrosion-resistant test chamber 1 and is fixedly connected to the top rotating wheel 13 at the front of one side. Two reciprocating grooves 46 are provided on the inner wall of the corrosion-resistant test chamber 1 at the front. The corrosion-resistant test chamber 1 is slidably connected to a reciprocating frame 39 through the two reciprocating grooves 46. Tooth grooves 44 are provided inside the reciprocating frame 39 at the top and bottom, and a tooth groove 44 is also provided at the bottom of the reciprocating frame 39.

[0026] In this embodiment, the second residual tooth 43 is meshed and connected with the tooth groove 44, the transmission worm wheel 40 is meshed and connected with the worm wheel groove 38, the tooth block 42 is meshed and connected with the tooth groove 44, the rotating wheel 13 rotates, driving the connecting shaft 37 to rotate, and driving the transmission worm wheel 40 to rotate through the worm wheel groove 38, thereby causing the second residual tooth 43 to rotate. During the continuous rotation of the second residual tooth 43, the second residual tooth 43 will first mesh with the tooth groove 44 at the top of the reciprocating frame 39, and then mesh with the tooth groove 44 at the bottom of the reciprocating frame 39, thereby causing the reciprocating frame 39 to perform horizontal reciprocating sliding motion along the two reciprocating grooves 46, causing the tooth groove 44 at the bottom of the reciprocating frame 39 to perform horizontal reciprocating motion, and then driving the scraper rod 41 to perform reciprocating rotation motion through the tooth block 42, so that the transparent observation area 45 can be continuously scraped and swept, so that the transparent observation area 45 can always remain transparent and clean during the device testing process, so that it is convenient for the tester to observe the corrosion of the corrosion-resistant coating inside the device through the transparent observation area 45.

[0027] In this embodiment, the maximum rotation angle of the scraper rod 41 is 180 degrees, the front portion of the scraper rod 41 is in contact with the transparent observation area 45, and the front portion of the scraper rod 41 is made of rubber material.

[0028] It should be noted that the present invention is a corrosion-resistant coating testing device. When in use, the top of a test plate 8 is evenly coated with corrosion-resistant coating, and the other test plate 8 is not processed in any way. The two test plates 8 are installed in the interior of the corrosion-resistant test chamber 1 through a plurality of clamping blocks 7. The specific steps are as follows: during the process of pressing down the test plate 8, the two clamping blocks 7 are squeezed, so that the two clamping blocks 7 expand and rotate outward, so that the two springs 12 are compressed. When the round rods at the ends of the test plate 8 are in the exact center of the two clamping blocks 7, the two springs 12 rebound, and the multiple pairs of clamping blocks 7 operate according to the above principle, so that the test plate 8 can be installed in the interior of the corrosion-resistant test chamber 1. At this time, the top cover 2 is closed, and the spray rod 10 is connected to the external water injection device through the rotating block 23. Corrosive liquid is sprayed into the interior of the corrosion-resistant test chamber 1 through the spray rod 10, wherein the test plate 8 not coated with corrosion-resistant coating is a blank control group. By observing the corrosion conditions of the two test plates 8, the corrosion resistance of the water-based material can be understood. The spray rod 10 can be driven to move by running the two spray rotating structures 3, so that the surface of the experimental plate 8 can be sprayed evenly. The specific steps are: the motor is running, and the toothed belt 14 near the bottom is driven to rotate by the two bottom wheels 13, and the wheel 13 near the bottom and located at the front on one side rotates, driving the bevel gear 1 16 near the bottom together with the rotating drum 18 near the bottom and the bevel gear 2 20 to rotate together, and the rotation of the rotating drum 18 near the bottom drives the rotating drum 18 near the top to rotate through the idle gear 19, and then the bevel gear 1 16 near the top and the bevel gear 2 20 are meshed with each other, driving the top wheel 13, and then driving the toothed belt 14 near the top to rotate, and the two toothed belts 14 rotate in opposite directions, thereby driving the spray rod 10 to move. In the process of the movement of the spray rod 10, the residual The tooth 1 26 moves. Since the tooth plate 15 is in a fixed state, and the residual tooth 1 26 is fixed on the outer surface of the spray rod 10, and the spray rod 10 and the block 22 are in a through-connected relationship, the residual tooth 1 26 can rotate. Therefore, during the movement of the residual tooth 1 26, through the meshing relationship with the tooth plate 15, the residual tooth 1 26 rotates together with the movement and rotation of the spray rod 10. The rotation of the spray rod 10 drives the rotating block 23 to rotate, so that the two springs 25 are respectively in a compressed and stretched state. When the spray rod 10 moves to the end of the slide slot 9, the output shaft of the motor reverses to drive the spray rod 10 to move back. During the moving back, the residual tooth 1 26 rotates 180 degrees in the opposite direction. Therefore, the spray rotating structure 3 can make the spray rod 10 move to spray and can reverse the spray direction. When the corrosive liquid is sprayed onto the surface of the corrosion-resistant coating, a chemical reaction will occur to generate gas, which will fly into the air through the three slide grooves 9, polluting the environment. Therefore, the slide groove 9 can be closed through the anti-leakage structure 4, even when the spray rod 10 moves, the slide groove 9 can be closed. The specific steps are as follows: during the movement of the spray rod 10, the sealing block 1 33 and the sealing block 3 35 will be squeezed through the inclined surface, so that several sealing blocks 1 33 and sealing blocks 3 35 will completely enter the interior of the storage groove 1 30 and the storage groove 3 32. At this time, several springs When the spray rod 10 continues to move, so that the spray rod 10 is no longer in contact with a certain sealing block 1 33 and a certain sealing block 35, the spring 36 rebounds, driving the sealing block 1 33 and the sealing block 35 to reset, so that this part of the slide groove 9 is closed. When the spray rod 10 moves to the end of the slide groove 9, the sealing block 2 34 will be squeezed through the inclined surface, so that the sealing block 2 34 is completely inserted into the interior of the receiving groove 2 31, and the spring 36 will be compressed. When the spray rod 10 moves back, the spring 36 rebounds, driving the sealing block 2 34 to reset, so that the end of the slide groove 9 is closed; When the corrosion test chamber 1 is subjected to a corrosion test, the corrosion-resistant coating reacts with the corrosive liquid to generate harmful gas. At this time, the exhaust fan 28 is running to extract the harmful gas inside the corrosion test chamber 1 to the inside of the gas storage chamber 27, and then connects to the external collection device through the connection hole 29 to completely collect the harmful gas. When the device is working, the tester observes the status of the two experimental plates 8 through the two transparent observation areas 45. However, when the device is working, the corrosive liquid and harmful gas will adhere to the transparent observation area 45, making the transparent observation area 45 blurry, and thus unable to be accurately observed. At this time, the reciprocating scraping structure 5 can be used to continuously ensure that the transparent observation area is in a clear state. The specific steps are as follows: the rotating wheel 13 rotates, driving the connecting shaft 37 to rotate, and driving the transmission worm wheel 40 to rotate through the worm wheel groove 38, thereby rotating the residual tooth 2 43. During the continuous rotation of the residual tooth 2 43, the residual tooth 2 4 3 will first mesh with the tooth groove 44 at the top of the reciprocating frame 39, and then mesh with the tooth groove 44 at the bottom of the reciprocating frame 39, so that the reciprocating frame 39 makes a horizontal reciprocating sliding motion along the two reciprocating grooves 46, so that the tooth groove 44 at the bottom of the reciprocating frame 39 makes a horizontal reciprocating motion, and then the scraper rod 41 is driven by the tooth block 42 to make a reciprocating rotation motion, so that the transparent observation area 45 can be continuously scraped and swept, so that the transparent observation area 45 can always remain transparent and clean during the device test process, so that it is convenient for the tester to observe the corrosion of the corrosion-resistant coating inside the device through the transparent observation area 45.

[0029] This embodiment also provides a corrosion-resistant coating, including epoxy resin, phenolic resin, amino resin, additives, solvents, methyl isobutyl ketone, alkyd-siloxane, aluminum powder, and coal tar, which is tested by the above-mentioned corrosion-resistant coating testing device.
