Description

Technical Field

[0001] The invention belongs to the technical field of coating detection, and in particular relates to a device for detecting the performance of highly corrosion-resistant color plate coil coatings. Background Art

[0002] Anticorrosion materials are materials specially used to prevent objects from chemical and electrochemical corrosion. They effectively isolate the corrosive medium from the material surface by forming a protective layer, changing the surface properties of the material, or providing electrochemical protection, thereby improving the durability and service life of the material. Common anticorrosion materials include organic and inorganic coatings, fiberglass, rubber products, inorganic sheets, etc., which are widely used in construction, chemical industry, marine engineering and other fields.

[0003] In actual operation, it is crucial to test the performance of the anti-corrosion materials on the surface of color plate coils. However, the current high-corrosion color plate coil coating performance testing device has obvious shortcomings. First, the device cannot track the status of the coating in real time, which means that we cannot immediately understand the anti-corrosion effect of the coating. Secondly, due to the long experimental cycle, the staff needs to regularly remove the test pieces from the test environment for inspection, which not only affects the accuracy of the experiment, but also increases the workload.

[0004] More specifically, current methods cannot accurately determine the point in time when the coating begins to deteriorate, which is crucial for testing the performance of anti-corrosion materials. In addition, existing testing methods also require cutting metal plates as test pieces, which not only increases the cost of the experiment, but also the subsequent metal plate recycling process is quite cumbersome, resulting in a waste of resources.

[0010] As a preferred embodiment of the present invention, an electric push rod is fixedly connected to one side of the box body, an output end of the electric push rod is fixedly connected to a connecting frame, and the first connecting rods are fixedly connected to the connecting frame.

[0011] As a preferred embodiment of the present invention, two symmetrical first rotating rods are installed in the box cover; Two symmetrical rhombus plates are fixedly connected to the outer surface of the first rotating rod, and the rhombus plates are located between the first detection plate and the second detection plate; A second cavity is provided inside the box cover; A liquid circulation channel is provided in each of the first rotating rods, and the liquid circulation channel can be communicated with the second cavity, and a water outlet hole is provided in each of the diamond-shaped plates; The water outlet hole can be communicated with the liquid circulation channel.

[0012] As a preferred embodiment of the present invention, two symmetrical slide plates are fixedly connected on both sides of the box body, and an electric slide is provided inside the slide plates. One side of the electric slide is slidably connected to the slide plates, and the other side of the electric slide is fixedly connected to the box cover.

[0013] As a preferred embodiment of the present invention, a first sliding groove is provided on the surface of the supporting plate, a first sliding block and a second sliding block are slidably connected in the first sliding groove, the upper side of the first sliding block is fixedly connected to the lower side of the first detection plate, the upper side of the second sliding block is fixedly connected to the lower side of the second detection plate, a first spring is fixedly connected between the first sliding block and the supporting plate, and a second spring is fixedly connected between the second sliding block and the first fixed plate.

By accurately measuring the height or thickness changes of the test sample, the anti-corrosion performance of the coating is evaluated in real time. Once the coating layer shows signs of damage, the detection component will immediately record the time node and feed back the relevant data to the control terminal for staff to conduct in-depth analysis and evaluation.

DETAILED DESCRIPTION

[0021] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0022] The structure of the present invention is described in detail below in conjunction with the accompanying drawings.

[0023] See also Figures 1 to 8A high-corrosion-resistant color plate coil coating performance detection device provided by an embodiment of the present invention includes a box body 1, a control terminal 11 is installed on one side of the box body 1, a box cover 12 is installed on the upper side of the box body 1, an anti-corrosion coating test piece 13 is installed on the bottom of the box body 1, and a carrying plate 14 is installed in the box body 1; a first fixed plate 15 is fixedly connected to the upper side of the carrying plate 14, and the first fixed plate 15 is located in the middle of the carrying plate 14; a first anti-corrosion coating detection component and a second anti-corrosion coating detection component are provided on both sides of the first fixed plate 15; a scraping component is installed on one side of the first anti-corrosion coating detection component and the second anti-corrosion coating detection component.

[0024] The above scheme is adopted: when using, when conducting the anti-corrosion test of the color plate coil coating, first apply the same coating as the color plate coil on the test piece, then place the first test piece between the first anti-corrosion coating test component and the carrier plate 14, ensuring that one side of the test piece is in contact with the first anti-corrosion coating test component and the other side is in contact with the edge of the carrier plate 14. Similarly, the second test piece is placed between the second anti-corrosion coating test component and the first fixed plate 15, with its two sides in contact with the second anti-corrosion coating test component and the first fixed plate 15 respectively, and the bottoms of the two test pieces are in contact with the carrier plate 14.

[0025] After the test pieces are placed, the box cover 12 will drop and fit with the box body 1 to form a closed testing environment. At this time, the scraping assembly moves and contacts the upper surfaces of the two test pieces during the movement, thereby removing excess paint and ensuring that the height or thickness of the test pieces remains consistent, providing an accurate basis for subsequent anti-corrosion testing.

[0026] Subsequently, the anti-corrosion coating test piece 13 will spray salt mist, which gradually covers the surface of the test piece to simulate the corrosion process. After waiting for a period of time, the salt mist will gradually corrode the coating, and the anti-corrosion performance of the coating can be tested at this time.

[0027] The first anti-corrosion coating detection component and the second anti-corrosion coating detection component monitor the status of the two test pieces respectively. As the coating gradually corrodes and peels off, the height or thickness of the test piece will change. The first anti-corrosion coating detection component and the second anti-corrosion coating detection component can monitor the height or thickness changes of the test piece in real time, record the time point when the coating begins to be damaged, and feed the data back to the control terminal 11 for staff to analyze, which not only significantly reduces the workload of the staff and improves the detection efficiency, but also can accurately evaluate the anti-corrosion performance of the coating through measurement and recording. In addition, since there is no need to cut the metal plate for testing, the waste of metal plates is avoided.

[0028] It should be noted that: First, since the first anti-corrosion coating detection component and the second anti-corrosion coating detection component are set on both sides of the first fixed plate 15, two test pieces can be placed on the other side of the first fixed plate 15 at this time, and the test piece placement position and requirements are the same as the above-mentioned scheme. Second, the number of the first anti-corrosion coating detection component and the second anti-corrosion coating detection component can be adjusted according to actual needs. At this time, the number of test pieces and scraping components also needs to be adjusted. Third, the height of the test piece after scraping should be flush with the height of the first test plate 2 and the second test plate 3. Fourth, the anti-corrosion coating test piece 13 is a salt spray tower.

[0029] Furthermore, the first anti-corrosion coating detection component includes a first detection plate 2 , which is located on the upper side of the carrier plate 14 , and a first distance sensor is installed in the first detection plate 2 , and the first distance sensor is signal-connected to the control terminal 11 .

[0030] Adopt the above scheme: when in use, in the process of testing the anti-corrosion performance of the coating, first place the test piece on the carrier plate 14 to ensure that the bottom of the test piece is in close contact with the surface of the carrier plate 14. Then, place the test piece in a salt spray environment to simulate corrosion conditions. As the salt spray corrodes the coating on the upper surface of the test piece, the coating will gradually fall off, causing the thickness of the test piece to change. At this time, the first distance sensor located in the first detection plate 2 will continuously monitor the distance between the bottom surface of the test piece and the upper surface of the test piece. Once the distance changes, it means that the coating begins to be damaged. The first distance sensor will record this time point and feed it back to the control terminal 11 in real time.

[0031] It should be noted that: first, the test piece is laid flat on the carrier plate 14. Second, since the test piece is laid flat on the carrier plate 14, the number of first distance sensors in the first detection plate 2 can be adjusted according to the length of the test piece to improve the detection accuracy.

[0032] Furthermore, the second anti-corrosion coating detection component includes a second detection plate 3, which is located on a side of the supporting plate 14 close to the first detection plate 2, and a second distance sensor is installed in the second detection plate 3, and the second distance sensor is signal-connected to the control terminal 11.

[0033] Adopting the above scheme: It should be noted that: first, the detection method of the second anti-corrosion coating detection component for the anti-corrosion performance of the coating is consistent with the detection method of the first anti-corrosion coating detection component. Second, the number of the second distance sensors in the second detection plate 3 can also be adjusted according to the length of the test piece.

[0034] Furthermore, the scraping assembly includes a first scraper 4 and a second scraper 41, the first scraper 4 is located between the first detection plate 2 and the edge of the supporting plate 14, the second scraper 41 is located between the second detection plate 3 and the first fixed plate 15, and the first scraper 4 and the second scraper 41 are both provided with a first connecting rod 42 on the back, one end of the first connecting rod 42 is inserted into the first scraper 4 and the second scraper 41, and the other end of the first connecting rod 42 can extend to the outside of the box body 1.

[0035] The above solution is adopted: when in use, when it is necessary to ensure that the height or thickness of the test piece is uniform, the first connecting rod 42 moves. The movement of the first connecting rod 42 drives the first scraper 4 to contact the surface of the first test piece. At the same time, since the back of the second scraper 41 is also provided with the first connecting rod 42, the first connecting rod 42 simultaneously drives the second scraper 41 to contact the surface of the second test piece. In this way, the first scraper 4 and the second scraper 41 can move synchronously to jointly scrape off the excess paint on the surfaces of the two test pieces, ensuring that the height or thickness of the two test pieces reaches the preset uniform standard.

[0036] It should be noted that: first, since the first scraper 4 is clamped on the first connecting rod 42, if the width of the specimen becomes smaller, the first scraper 4 can be removed from the first connecting rod 42 and replaced with a first scraper 4 with a similar width to the specimen. Second, the second scraper 41 can also be adjusted according to the width of the specimen, and the replacement method is the same as above.

[0037] Furthermore, an electric push rod 5 is fixedly connected to one side of the box body 1 , an output end of the electric push rod 5 is fixedly connected to a connecting frame 51 , and the first connecting rods 42 are fixedly connected to the connecting frame 51 .

[0038] The above solution is adopted: when in use, when the first connecting rod 42 needs to move, the output end of the electric push rod 5 drives the first connecting rod 42 to be extended and retracted synchronously through the connecting frame 51, so that the first connecting rod 42 can drive the first scraper 4 and the second scraper 41 to move.

[0039] Furthermore, two symmetrical first rotating rods 6 are installed in the box cover 12; Two symmetrical diamond plates 61 are fixedly connected to the outer surface of the first rotating rod 6, and the diamond plates 61 are located between the first detection plate 2 and the second detection plate 3; a second cavity 62 is opened inside the box cover 12; a liquid circulation channel 63 is opened in the first rotating rod 6, and the liquid circulation channel 63 can be interconnected with the second cavity 62, and a water outlet hole 64 is opened in the diamond plate 61; the water outlet hole 64 can be interconnected with the liquid circulation channel 63.

[0040] The above scheme is adopted: when in use, when the specimen is placed on the carrier plate 14 and needs to be sorted, the box cover 12 is in a descending state. When the box cover 12 descends, the first rotating rod 6 drives the diamond plate 61 to descend synchronously. During the descent of the diamond plate 61, due to the shape of the diamond plate 61, the lower part changes from narrow to wide, and the upper part changes from wide to narrow. The lower part of the diamond plate 61 will first contact the first detection plate 2 and the second detection plate 3, and gradually expand the distance between the two. This expansion of the distance will push the first detection plate 2 and the second detection plate 3 to approach the edge of the carrier plate 14 and the first fixed plate 15 respectively, thereby squeezing and sorting the specimen placed on the carrier plate 14. When the width of the specimen is small, and the diamond plate 61 drops to the extreme position while the specimen is still tilted and there is a gap, at this time, the first rotating rod 6 drives the diamond plate 61 to rotate from 90 degrees to 180 degrees. During the rotation process, the lower and upper parts of the diamond plate 61 will contact the first test plate 2 and the second test plate 3 respectively, and the force generated by this contact will further push the two test plates to move, thereby adjusting the position of the test piece. Subsequently, the liquid in the second cavity 62 flows from the liquid circulation pipe to the water outlet 64. At this time, the diamond plate 61 is in contact with the first test plate 2 and the second test plate 3. The liquid gradually flows onto the surface of the test piece through the water outlet 64, thereby realizing a rapid test of the anti-corrosion performance of the coating.

[0041] The above scheme has the following effects: First, if the above-mentioned scheme is not set up, the specimens may be in a messy state when placed on the supporting platform, which will not only reduce the efficiency of specimen detection, but also affect the accuracy of detection, especially in the process of scraping off excess paint on the surface of the specimen, the specimen may cause inconsistent thickness due to shaking, further affecting the detection result. After setting up the above-mentioned scheme, the descent of the diamond plate 61 will push the first detection plate 2 and the second detection plate 3 to the edge of the supporting plate 14 and the first fixed plate 15 respectively, thereby squeezing and arranging the specimens placed on the supporting plate 14. If the excess paint on the surface of the specimen needs to be scraped off, the diamond plate 61 will press the first detection plate 2 and the second detection plate 3 tightly, thereby avoiding the shaking of the specimen.

[0042] Second, when the width of the specimen is small, if the above-mentioned scheme is not set, the diamond plate 61 has been lowered to the extreme position, part of the specimen is still at an inclined angle, and there is still a certain gap between the specimen and the first detection plate 2 and the second detection plate 3. At this time, the specimen will still shake and be placed unevenly. After setting the above-mentioned scheme, the first rotating rod 6 drives the diamond plate 61 to adjust the angle, which will push the first detection plate 2 and the second detection plate 3 to move and squeeze the specimen again. During the squeezing process, the specimen position will gradually be tightened and adjusted to accommodate specimens of different widths.

[0043] Third, when spraying liquid over a large area, if the above-mentioned scheme is not set up, part of the sprayed liquid will fall on the surface of the specimen, and the remaining part will not be sprayed on the surface of the specimen, resulting in a waste of liquid. After setting up the above-mentioned scheme, since the height of the specimen is consistent with the height of the first test plate 2 and the second test plate 3, when the diamond plate 61 contacts the first test plate 2 and the second test plate 3, the liquid can flow directly from the first test plate 2 and the second test plate 3 to the specimen.

[0044] It should be noted that: first, an external pump body can be used to deliver liquid into the second cavity 62. Second, the liquid in the second cavity 62 is an acidic solution. Third, a one-way valve can be installed in the liquid circulation pipeline to control the inflow and outflow of the liquid.

[0045] Furthermore, two symmetrical slide plates 7 are fixedly connected on both sides of the box body 1, and an electric slide 71 is provided inside the slide plate 7. One side of the electric slide 71 is slidably connected to the slide plate 7, and the other side of the electric slide 71 is fixedly connected to the box cover 12.

[0046] The above scheme is adopted: when in use, when the box cover 12 needs to be raised or lowered, the electric slide 71 rises or falls in the slide plate 7, and when the electric slide 71 is raised or lowered, it will drive the box cover 12 to be raised or lowered synchronously.

[0047] Furthermore, a first sliding groove 8 is opened on the surface of the supporting plate 14, and a first sliding block 81 and a second sliding block 82 are slidably connected in the first sliding groove 8. The upper side of the first sliding block 81 is fixedly connected to the lower side of the first detection plate 2, and the upper side of the second sliding block 82 is fixedly connected to the lower side of the second detection plate 3. A first spring is fixedly connected between the first sliding block 81 and the supporting plate 14, and a second spring is fixedly connected between the second sliding block 82 and the first fixed plate 15.

[0048] Adopting the above scheme: when in use, when the first detection plate 2 and the second detection plate 3 are driven, the first detection plate 2 and the second detection plate 3 will move in opposite directions respectively. The first detection plate 2 pushes the first sliding block 81 to move in the first slide groove 8 toward the edge of the carrier plate 14, while the second detection plate 3 pushes the second sliding block 82 to move in the same slide groove toward one side of the first fixed plate 15. At the same time, since the first detection plate 2 and the second detection plate 3 move in opposite directions, it is ensured that the first detection plate 2 and the second detection plate 3 can respectively squeeze the test piece during the movement, and the necessary buffer and stability are provided by the compression of the first spring and the second spring. At the same time, the first spring and the second spring can also respectively drive the first sliding block 81 and the second sliding block 82 to reset.

[0049] Furthermore, a forward and reverse motor 9 is installed on the upper side of the box cover 12, and the output end of the forward and reverse motor 9 is fixedly connected to a first sprocket 91, and the outer surface of one of the first rotating rods 6 is fixedly connected to a second sprocket 92, and a first chain 93 is installed between the first sprocket 91 and the second sprocket 92.

[0050] The above scheme is adopted: when in use, when the first rotating rod 6 needs to be rotated, the output end of the forward and reverse motor 9 drives the first sprocket 91 to rotate. During the rotation of the first sprocket 91, the second sprocket 92 is driven to rotate synchronously through the first chain 93. Since the second sprocket 92 is connected to the first rotating rod 6, the rotation of the second sprocket 92 will drive the first rotating rod 6 to rotate. In addition, since the diamond plate 61 is fixed to the first rotating rod 6, when the first rotating rod 6 rotates forward and reverse, the diamond plate 61 will also follow it to perform the same action.

[0051] It should be noted that the rotation speed of the output end of the forward and reverse motor 9 is relatively slow and can be adjusted according to actual needs.

[0052] Working principle of the present invention: When evaluating the anti-corrosion performance of the color plate coil coating, first, the same coating layer as the color plate coil needs to be applied to the test piece. Then, the first test piece is placed between the first anti-corrosion test assembly and the carrier plate 14, ensuring that one side of it is tightly fitted with the first anti-corrosion test assembly and the other side is in contact with the edge of the carrier plate 14. Similarly, the second test piece is placed between the second anti-corrosion test module and the first fixed plate 15, ensuring that its two sides are in contact with the second anti-corrosion test assembly and the first fixed plate 15 respectively, and the bottoms of the two test pieces are flush with the carrier plate 14.

[0053] After the test pieces are placed, the box cover 12 will drop until it is completely closed with the box body 1, thus constructing a closed testing environment. Then, the scraping assembly is started so that it contacts the top surface of the two test pieces during the movement to remove excess paint, ensuring that the height or coating thickness of the test pieces reaches a uniform standard, laying an accurate foundation for subsequent anti-corrosion testing.

[0054] Subsequently, the anti-corrosion coating test piece 13 begins to release salt mist, which gradually covers the surface of the test piece, simulating a real corrosion environment. After a period of standing, the salt mist will corrode the coating layer, and at this time we can begin to evaluate the anti-corrosion performance of the coating.

[0055] The first anti-corrosion test assembly and the second anti-corrosion test assembly are responsible for monitoring the status of the two test pieces respectively. As the coating layer gradually corrodes and peels off, the height or coating thickness of the test piece will change. The two test assemblies can detect these changes in real time and record the specific time point when the coating begins to fail, and then transmit these data to the control terminal 11 for staff to conduct in-depth analysis and evaluation.
