Description

Technical Field

[0001] This invention belongs to the field of coating testing technology, and in particular relates to a dynamic testing device and testing method for anti-corrosion coatings. Background Technology

[0002] Anti-corrosion coatings are an essential type of paint, primarily used to protect materials such as metals and concrete from corrosion. They work by forming a dense protective film on the material surface, preventing the penetration of moisture, oxygen, and corrosive substances, thus effectively preventing metal from rusting and corroding. Anti-corrosion coatings can generally be divided into conventional anti-corrosion coatings and heavy-duty anti-corrosion coatings.

[0003] After the development of anti-corrosion coatings is completed, evaluating their performance is a crucial task. A common evaluation method involves applying the coating to a specific substrate (such as a metal plate) and then immersing these coated substrates in salt water. After a period of time, the coating's performance is assessed by examining the anti-corrosion effect on the substrate.

[0004] However, this method has a significant limitation: it simulates a static aquatic environment, which differs greatly from the dynamic environment of water flow with its impact in real-world applications. Therefore, the results obtained from this static evaluation method cannot comprehensively and objectively reflect the performance of anti-corrosion coatings in practical applications. Furthermore, most devices use a fixed method when placing the substrate, making it impossible to adjust the angle as needed to simulate the diversity of actual working environments. Summary of the Invention

[0007] An angle adjustment component is installed on one side of the first disk;

[0008] A dynamic detection component is installed on the other side of the first disk.

[0009] As a preferred embodiment of the present invention, the angle adjustment component includes a first rotating shaft;

[0011] A motor is installed on the outside of the detection box, and the output end of the motor is fixedly connected to the first rotating shaft.

[0012] As a preferred embodiment of the present invention, the dynamic detection component includes a first liquid flow pipe, one end of which is installed inside the detection box, and the other end of which is installed outside the detection box.

[0013] A nozzle is fixedly connected to one end of the first liquid flow pipe, and the nozzle is located inside the detection box.

[0014] As a preferred embodiment of the present invention, a liquid storage tank is installed at the bottom of the detection box, and one end of the first liquid flow pipe is fixedly connected to one side of the liquid storage tank, and the first liquid flow pipe can communicate with the liquid storage tank.

[0015] In a preferred embodiment of the present invention, a plurality of first fixing plates are fixedly connected to the back of the first disc, each of the first fixing plates is provided with a first spring, one end of each of the first springs is fixedly connected to the first fixing plate, and the other end of each of the first springs is fixedly connected to a support plate. Each of the support plates is fixedly connected to a first support frame, and each of the first support frames is rotatably connected to a rolling roller.

[0016] As a preferred embodiment of the present invention, a third opening groove is provided on the upper side of the liquid storage tank;

[0017] A first airbag is installed in the third opening slot. The upper half of the first airbag extends into the detection box, and the lower half of the first airbag extends into the liquid storage tank. The two sides of the first airbag are fixedly connected to the edge of the third opening slot.

[0018] A second airbag is installed on the lower side of the first airbag. The second airbag is located inside the liquid storage tank, and the two sides of the second airbag are fixedly connected to the liquid storage tank.

[0019] As a preferred embodiment of the present invention, two symmetrical second support frames are fixedly connected to the upper side of the liquid storage tank. The second support frames are respectively located on both sides of the first airbag, and a second spring is fixedly connected between the second support frame and the first airbag.

[0020] As a preferred embodiment of the present invention, two symmetrical first slides are provided in the second opening groove, each of which is slidably connected to an electric slider, and an arc-shaped baffle is fixedly connected between the two electric sliders.

[0021] A dynamic testing method for anti-corrosion coatings includes the following steps:

[0022] Step S1: Apply the anti-corrosion coating evenly to the substrate;

[0023] Step S2: The substrate is fed into the mounting groove through the first opening groove and the second opening groove;

[0027] When conducting performance testing of anti-corrosion coatings, firstly, ensure that the anti-corrosion coating is evenly applied to the designated substrate. Next, to evaluate the material's performance, the substrate must pass through a preset path, first entering the first opening slot connected to the testing chamber, and then entering the mounting slot through the second opening slot.

[0028] After the substrate enters the mounting slot, the dynamic detection component is activated, which releases a specific liquid. This liquid comes into direct contact with the substrate surface on the first disk, and then interacts with the anti-corrosion coating on the substrate to test its performance.

[0029] If the substrate angle needs to be adjusted for more comprehensive detection, the angle adjustment component will be activated, driving the first disk to rotate. Since the substrate is securely fixed to the first disk, it will rotate synchronously with the disk, thus adjusting the angle. During this process, the dynamic detection component will continuously spray liquid to ensure that all angles of the substrate are effectively detected, thereby ensuring the comprehensiveness and accuracy of the detection results.

[0039] To further understand the invention's content, features, and effects, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0040] The structure of the present invention will now be described in detail with reference to the accompanying drawings.

[0041] Please see Figures 1 to 8 This invention provides a dynamic testing device for anti-corrosion coatings, comprising a testing box 1, a first opening groove 14 on the upper side of the testing box 1, a first disc 11 inside the testing box 1, a second opening groove 12 on the upper side of the first disc 11, an installation groove 13 inside the first disc 11, and the second opening groove 12 communicating with the installation groove 13; an angle adjustment component is installed on one side of the first disc 11; and a dynamic testing component is installed on the other side of the first disc 11.

[0042] Using the above scheme: In actual operation of testing anti-corrosion coatings, the anti-corrosion coating is first evenly applied to the substrate. When performance evaluation of these anti-corrosion coatings is required, the substrate is fed into the first opening slot 14, which is connected to the testing chamber 1, allowing the substrate to enter the testing chamber 1. Subsequently, the substrate is fed into the second opening slot 12, which is connected to the mounting slot 13, allowing the substrate to be directly fed into the mounting slot 13.

[0043] After the substrate enters the mounting groove 13, the dynamic detection component sprays a specific liquid. The liquid comes into contact with the surface of the substrate located on the first disk 11, and then interacts with the anti-corrosion coating on the substrate, thereby detecting the performance of the anti-corrosion coating.

[0044] When the substrate angle needs to be adjusted for more comprehensive testing, the angle adjustment component drives the first disk 11 to rotate. Since the substrate is fixed on the first disk 11, it rotates along with the first disk 11, thereby adjusting the substrate angle. During this process, the dynamic detection component continues to spray liquid to ensure that the substrate surface is covered with liquid regardless of its angle, thus achieving efficient and comprehensive testing of the anti-corrosion coating performance.

[0045] It should be noted that the liquid sprayed in the dynamic testing component is brine, but it can be replaced with other types of liquids depending on the specific needs. For example, when testing the reaction of anti-corrosion coatings to an acidic environment, an acidic solution can be used; and when simulating an alkaline environment, an alkaline solution can be used. These alternative liquids can effectively test the anti-corrosion coatings, ensuring that their performance can be verified in various environments.

[0046] Please see Figure 4 and Figure 6 The angle adjustment component includes a first rotating shaft 2; one end of the first rotating shaft 2 is fixedly connected to one side of the first disc 11, and the other end of the first rotating shaft 2 can extend to the outside of the detection box 1; a motor 21 is provided on the outside of the detection box 1, and the output end of the motor 21 is fixedly connected to the first rotating shaft 2.

[0047] The above solution works as follows: When the angle of the first disk 11 needs to be adjusted, the output of the motor 21 rotates, causing the first rotating shaft 2 to rotate synchronously. The rotation of the first rotating shaft 2 further synchronizes the first disk 11 and the substrate, thereby adjusting the angle of the first disk 11. This ensures that the substrate remains synchronized with the first disk 11 when adjusting the angle, allowing the substrate to be completely covered by the liquid at any angle. This effectively solves the problem of uneven contact area of ​​the anti-corrosion coating caused by the fluidity of the liquid when the substrate is fixed, ensuring that the liquid can completely cover the surface of the substrate, thus improving the efficiency of anti-corrosion coating detection.

[0048] Please see Figure 2 , Figure 4 and Figure 7 The dynamic detection component includes a first liquid flow pipe 3, one end of which is installed inside the detection box 1, and the other end of which is installed outside the detection box 1; a nozzle 31 is fixedly connected to one end of the first liquid flow pipe 3, and the nozzle 31 is located inside the detection box 1.

[0049] The above-described scheme involves the following steps: During the liquid spraying process on the substrate surface, initially, the liquid flows through the first liquid flow channel 3, and then enters the nozzle 31. Upon entering the nozzle 31, the liquid is evenly sprayed onto the substrate surface, coming into contact with the pre-coated anti-corrosion coating. This contact allows for effective testing of the anti-corrosion effect or other specific properties of the coating. However, not all sprayed liquid directly contacts the substrate surface; some liquid fails to reach the substrate for various reasons. This portion of the liquid eventually flows into the bottom of the testing chamber 1, facilitating subsequent analysis and reuse, effectively avoiding resource waste.

[0050] Please see Figure 2 , Figure 7 and Figure 8 The bottom of the detection box 1 is equipped with a liquid storage tank 4, and one end of the first liquid flow pipe 3 is fixedly connected to one side of the liquid storage tank 4. The first liquid flow pipe 3 can communicate with the liquid storage tank 4.

[0051] Using the above scheme: When liquid needs to flow into the first liquid flow pipe 3, the liquid in the storage tank 4 can enter the first liquid flow pipe 3, and then the liquid reaches the nozzle 31 through the first liquid flow pipe 3.

[0052] Please see Figure 4 The back of the first disc 11 is fixedly connected to a plurality of first fixing plates 5. Each of the first fixing plates 5 is provided with a first spring 51. One end of each of the first springs 51 is fixedly connected to the first fixing plate 5. The other end of each of the first springs 51 is fixedly connected to a support plate 52. Each of the support plates 52 is fixedly connected to a first support frame 53. Each of the first support frames 53 is rotatably connected to a rolling roller 54.

[0053] Using the above scheme: In use, when the liquid level at the bottom of the detection tank 1 is almost close to the bottom of the first disc 11, the first disc 11 rotates. This rotation drives the first spring 51 connected to it, and through the action of the first fixing plate 5, the first spring 51 and the first disc 11 rotate synchronously. Then, the rotation of the first spring 51 pushes the first support frame 53 to rotate. The crushing roller 54 on the first support frame 53 rotates together with the first support frame 53.

[0054] During the rotation of the pressing roller 54, it comes into contact with the liquid at the bottom of the detection chamber 1. Through the rotation of the pressing roller 54, it effectively pushes the contacting liquid outwards. It is important to note that to achieve this process, a water outlet must be pre-installed at the bottom of the detection chamber 1 to ensure that the liquid, after being pushed by the pressing roller 54, can flow out through this outlet to the outside.

[0055] In addition, due to its own elastic properties, the first spring 51 can provide additional thrust to the rolling roller 54 while the rolling roller 54 pushes the liquid, ensuring that the liquid can be dispersed to the outside.

[0056] It should be noted that: First, the preset diameter of the water outlet can be adjusted according to actual needs. Second, the preset water outlet must be located at the bottom of the testing box 1 and aligned longitudinally with the rolling roller 54. Third, a one-way valve can also be installed inside the preset water outlet to control the flow of liquid.

[0057] Please see Figures 5 to 8 The upper side of the liquid storage tank 4 is provided with a third opening groove 6; a first airbag 61 is installed in the third opening groove 6, the upper half of the first airbag 61 extends into the detection box 1, the lower half of the first airbag 61 extends into the liquid storage tank 4, and the two sides of the first airbag 61 are fixedly connected to the edge of the third opening groove 6; a second airbag 62 is installed on the lower side of the first airbag 61, the second airbag 62 is located in the liquid storage tank 4, and the two sides of the second airbag 62 are fixedly connected to the liquid storage tank 4.

[0058] Using the above scheme: When the rolling roller 54 rotates with the first disc 11 to the bottom of the detection box 1, it will contact the first airbag 61 at a 180-degree angle that is laid flat on the storage tank 4. As the rolling roller 54 rotates, for example, when the first rolling roller 54 rotates to 90 degrees, the first rolling roller 54 will contact the first airbag 61 and compress it, so that the first airbag 61 enters the storage tank 4 through the third slot. At this time, the second rolling roller 54 located on the first disc 11 also begins to move towards the first airbag 61, forming a cyclic compression. The compression of the first airbag 61 gradually causes it to sink towards the second airbag 62, thereby compressing the second airbag 62. The deformation of the first airbag 61 and the second airbag 62 together change the volume inside the storage tank 4.

[0059] The above solution achieves the following results:

[0060] First, when the pump body is used to draw liquid from the storage tank 4, if the above-mentioned scheme is not set, if the pump body draws liquid too quickly or the water volume in the storage tank 4 is low, it will cause negative pressure to form in the storage tank 4, which will lead to deformation or rupture of the storage tank 4. After setting the above-mentioned scheme, the first air bag 61 and the second air bag 62 are inserted into the storage tank 4. As the liquid decreases, the first air bag 61 and the second air bag 62 will expand and occupy part of the space, thereby preventing the formation of negative pressure.

[0061] Secondly, when the equipment is moving and the pump is not needed to draw liquid from the storage tank 4, there is no liquid left at the bottom of the detection tank 1, and the storage tank 4 is full. Without the above-mentioned scheme, when the storage tank 4 is full, the liquid inside will naturally flow through the first liquid flow pipe 3 and smoothly enter the nozzle 31 for spraying. However, once the amount of liquid in the storage tank 4 is insufficient to maintain this continuous overflow, the liquid supply inside the nozzle 31 will be insufficient, resulting in a weakened or interrupted spraying effect. With the above-mentioned scheme, when the liquid in the storage tank 4 is insufficient to maintain the overflow, as the liquid level drops, the first airbag 61 and the second airbag 62 will enter the storage tank 4. The intervention of the first airbag 61 and the second airbag 62 creates a pressure difference by changing the volume inside the storage tank 4, thereby driving the liquid to flow into the first liquid flow pipe 3. This not only promotes the flow of liquid but also increases the pressure, allowing the liquid to flow out of the storage tank 4 more quickly.

[0062] It should be noted that the rotation speed of the rolling roller 54 directly affects the deformation speed of the first airbag 61, and thus the rotation speed of the rolling roller 54 can be adjusted according to actual needs.

[0063] Please see Figure 5The upper side of the liquid storage tank 4 is fixedly connected to two symmetrical second support frames 7. The second support frames 7 are located on both sides of the first airbag 61. A second spring 71 is fixedly connected between the second support frame 7 and the first airbag 61.

[0064] Using the above scheme: When the first airbag 61 deforms and sinks, the first airbag 61 will pull the second spring 71 to sink synchronously. If the rolling roller 54 does not contact the first airbag 61, the second spring 71 will use its own elasticity to pull the deformed first airbag 61 to gradually rise and move closer to the second support frame 7, effectively improving the efficiency of the first airbag 61's reset, and making it easier for the rolling roller 54 to drive the first airbag 61 to sink again.

[0065] Please see Figure 3 The second opening groove 12 has two symmetrical first slides 8, each of which is slidably connected to an electric slider 81, and an arc-shaped baffle 82 is fixedly connected between the two electric sliders 81.

[0066] Using the above solution: When the substrate is placed in the mounting groove 13, the electric slider 81 drives the arc-shaped baffle 82 to move within the first slide rail 8, so that the mounting groove 13 is in a closed state.

[0067] A dynamic testing method for anti-corrosion coatings includes the following steps:

[0068] Step S1: Apply the anti-corrosion coating evenly to the substrate;

[0069] Step S2: The substrate is fed into the mounting groove 13 through the first opening groove 14 and the second opening groove 12.

[0070] Step S3: The dynamic detection component sprays a specific liquid, which comes into contact with the substrate surface on the first disk 11 and interacts with the anti-corrosion coating on the substrate to detect the performance of the anti-corrosion coating.

[0071] In step S4, the angle adjustment component drives the substrate to adjust its angle via the first disk 11.

[0072] Working principle of the invention:

[0073] In the actual operation of anti-corrosion coating testing, the first step is to ensure that the anti-corrosion coating is evenly applied to the substrate. When the performance evaluation of these anti-corrosion coatings is required, the substrate is first placed in the first opening slot 14, which is directly connected to the testing chamber 1, so that the substrate can smoothly enter the internal space of the testing chamber 1.

[0074] Next, the substrate is pushed further into the second opening groove 12, which is connected to the mounting groove 13 to ensure that the substrate can smoothly enter the mounting groove 13.

[0075] Once the substrate is fully inserted into the mounting slot 13, the dynamic detection component is activated and begins spraying a specific test liquid. This liquid comes into direct contact with the substrate surface located on the first disk 11, reacting chemically with the anti-corrosion coating thereon to evaluate the performance of the anti-corrosion coating.

[0076] To obtain a more comprehensive evaluation result by performing multi-angle testing on the substrate, the angle adjustment component is activated, causing the first disk 11 to rotate. Since the substrate is fixed on the first disk 11, it adjusts its angle as the disk rotates. During this process, the dynamic detection component continuously sprays liquid to ensure that the surface of the substrate is evenly covered with liquid regardless of its angle, thereby achieving comprehensive and efficient testing of the anti-corrosion coating performance.
