Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of coating quality detection, in particular to a dynamic environment simulation test device and method for evaluating condensation prevention performance of a coating. BACKGROUND

[0002] In high-humidity and high-temperature difference environments such as hydropower stations, tunnels, underground pipe galleries and deep water pump rooms, the surfaces of metal pipelines and equipment conveying cold medium are prone to condensation due to temperature difference. Condensation not only causes coating blistering and peeling, accelerating the corrosion of the metal substrate, but also may cause safety hazards such as electrical equipment short circuit and structural strength reduction, resulting in frequent shutdown for maintenance and huge economic losses. The conventional solution is to coat the surface of the metal pipeline and equipment with a condensation prevention coating. However, in actual applications, the effects achieved by the condensation prevention coating vary depending on the environment. To verify whether the effect of the condensation prevention coating meets the use requirements, the metal pipeline or equipment coated with the condensation prevention coating needs to be applied in the corresponding environment. This verification method is not only affected by factors such as season and weather, but also faces problems such as non-reproducible data, complex installation and debugging, and difficult observation and recording, making it difficult to meet the needs of research and development and quality control.

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0024] Reference Figures 1 to 6 The embodiment of the present application provides a dynamic environment simulation test device for evaluating condensation prevention performance of a coating, which comprises a simulation test box 100, the simulation test box 100 comprises a transparent shell 110, a coating carrier 120 with a cavity, a temperature detection device 130, a display screen 140, a temperature and humidity adjusting module 150 and a first control panel 160; the coating carrier 120 is arranged in the transparent shell 110, the cavity of the coating carrier 120 is used for injecting cooling water (such as deionized water), and the surface of the coating carrier 120 is used for coating a coating to be measured or carrying a sample 121 with the coating to be measured; the cooling water is used for cooling the coating to be measured on the coating carrier 120, so that the temperature thereof is reduced below the dew point temperature; the temperature detection device 130 is arranged on the surface of the coating carrier 120 and is used for detecting the temperature of the surface of the coating carrier 120 (i.e. the temperature of the coating to be measured); the display screen 140 is arranged in (the transparent shell 110) and is electrically connected with the temperature detection device, and is used for displaying the temperature of the surface of the coating carrier 120; the temperature and humidity adjusting module 150 is arranged in the transparent shell 110 and is used for adjusting the internal temperature and humidity of the transparent shell 110; the first control panel 160 is arranged in the transparent shell 110 and is electrically connected with the temperature and humidity adjusting module 150, and the first control panel 160 is used for controlling the adjusting parameters (i.e. the target temperature and the target humidity) of the temperature and humidity adjusting module 150.

[0025] When the dynamic environment simulation test device for evaluating the anti-condensation performance of the coating is used for testing, the operator can adjust the temperature and humidity inside the transparent shell 110 through the temperature and humidity adjusting module 150, so as to simulate the temperature and humidity of the actual working environment. The cooling water injected into the coating carrier 120 can cool the coating to be tested on the coating carrier 120, so that the temperature of the coating to be tested is reduced to below the dew point temperature, thereby simulating the formation and development process of the condensation on the surface of the coating to be tested in the real working environment. While observing the formation and development process of the condensation on the surface of the coating to be tested through the transparent shell 110, the operator can also observe the temperature of the surface of the coating carrier 120, so as to determine whether the surface temperature of the coating to be tested reaches the dew point temperature, thereby avoiding the influence of the test result caused by the fact that the coating to be tested does not reach the condensation condition. At the same time, the temperature of the cooling water can also be combined to judge the temperature insulation effect of the coating to be tested. It can be seen that the dynamic environment simulation test device for evaluating the anti-condensation performance of the coating can highly simulate the real working condition, support the evaluation of the anti-condensation performance of the coating sample in multiple forms, and provide a scientific basis for the research and development, selection and engineering application of the anti-condensation coating.

[0026] It should be noted that the coating carrier 120 coated with the coating to be tested can be a part coated with the coating to be tested, such as a pipeline, a metal container and the like used in the actual working condition.

[0027] In some embodiments, the transparent shell 110 is provided with an opening 111 and a sealing door 112 arranged at the opening 111, and the sealing door 112 is used to open and close the opening 111. In this way, the user can conveniently assemble and disassemble the coating carrier 120 and clean the inside of the transparent shell 110. Specifically, after the sealing door 112 is opened, the operator can assemble and disassemble the coating carrier 120 and clean the inside of the transparent shell 110, and after the sealing door 112 is closed, the test can be started.

[0028] In some embodiments, the sealing door 112 can be opened and closed in a detachable manner. For example, the sealing door 112 is detachably arranged on the transparent shell 110 through a plurality of buckle structures 113 (magnetic buckle structures) to expose or close the opening 111, wherein the plurality of buckle structures 113 are spaced apart along the circumference of the sealing door 112, and each buckle structure 113 includes a first buckle member and a second buckle member. The first buckle member is arranged on the transparent shell 110, and the second buckle member is correspondingly arranged on the sealing door 112. When the sealing door 112 covers the opening 111, the first buckle member and the second buckle member can cooperate with each other to mount the sealing door 112 on the transparent shell 110, so as to close the opening 111. Of course, in other embodiments, the sealing door 112 can also be opened and closed in a movable manner relative to the transparent shell 110.

[0029] In some embodiments, a sealing strip is arranged at the position where the periphery of the opening 111 corresponds to the sealing door 112, so as to improve the sealing effect of the sealing door 112. That is, when the sealing door 112 is closed, the sealing strip is arranged between the transparent shell 110 and the sealing door 112, so as to close the gap between the transparent shell 110 and the sealing door 112, and improve the sealing effect of the sealing door 112.

[0030] In some embodiments, the transparent shell 110 is made of a transparent acrylic material plate. Specifically, the transparent shell 110 and the sealing door 112 thereof are made of a transparent acrylic material plate. Of course, in other embodiments, the transparent shell 110 can also be made of other transparent materials, such as glass.

[0031] In some embodiments, the cavity of the coating carrier 120 is used for cooling water to flow through. That is, the coating carrier 120 has a water inlet and a water outlet connected to the cavity, the water inlet is used for cooling water to flow into the cavity of the coating carrier 120, and the water outlet is used for cooling water to flow out of the cavity of the coating carrier 120. It should be understood that in specific implementations, the coating carrier 120 can be a pipeline or a water tank with a water inlet and a water outlet.

[0032] In some embodiments, the device further comprises a constant-temperature water bath 200, the water outlet of the constant-temperature water bath 200 is connected to the water inlet of the coating carrier 120, and the water inlet of the constant-temperature water bath 200 is connected to the water outlet of the coating carrier 120, so as to circulate constant-temperature cooling water between the constant-temperature water bath 200 and the coating carrier 120. That is, the constant-temperature water bath 200 and the cavity of the coating carrier 120 can form a circulating water path. Under the action of the constant-temperature water bath 200, the constant-temperature cooling water can circulate in the circulating water path, and when the constant-temperature cooling water passes through the cavity of the coating carrier 120, it can cool the coating under test to a temperature below the dew point temperature, so as to realize condensation, which can simulate the condensation of a part or equipment conveying constant-temperature cooling water. It should be noted that the circulating constant-temperature cooling water specifically refers to that the constant-temperature water bath 200 outputs cooling water, the cooling water increases in temperature when passing through the coating carrier 120 and returns to the constant-temperature water bath 200, and the constant-temperature water bath 200 restores the returned cooling water to the initial temperature and then outputs it again.

[0033] In some embodiments, the constant-temperature water bath 200 comprises a box body 210, a temperature control assembly, a water pump and a second control panel 220; the box body 210 is provided with cooling water, the water outlet of the box body 210 is communicated with the water inlet of the coating carrier 120, and the water inlet of the box body 210 is communicated with the water outlet of the coating carrier 120; the temperature control assembly is arranged in the box body 210 and used for adjusting the temperature of the cooling water to keep it constant; the water pump is arranged in the box body 210 and used for providing circulating power to the cooling water; the second control panel 220 is arranged in the box body 210 and electrically connected with the temperature control assembly and the water pump, and the second control panel 220 is used for controlling the adjustment parameters of the temperature control assembly and controlling the start and stop of the water pump, the adjustment parameters including temperature adjustment parameters (such as 5-30℃). That is, the box body 210 of the constant-temperature water bath 200 and the cavity of the coating carrier 120 can form a circulating water path. During the test, the operator can control the water pump through the second control panel 220 to make the constant-temperature cooling water circulate in the circulating water path. In addition, the operator can also set the temperature value of the cooling water through the second control panel 220 to make the temperature control assembly adjust the cooling water to the set temperature value. It should be noted that the specific structure of the box body 210, the temperature control assembly and the control panel of the constant-temperature water bath 200 belongs to the prior art, and the embodiments of the present application will not be described in detail.

[0034] In some embodiments, the side wall of the transparent shell 110 is provided with a water inlet hole and a water outlet hole. The water outlet of the constant-temperature water bath 200 and the water inlet of the coating carrier 120 are communicated through the water inlet hole, and the water inlet of the constant-temperature water bath 200 and the water outlet of the coating carrier 120 are communicated through the water outlet hole. In this way, the constant-temperature water bath 200 can be moved outside the simulation test box 100, which helps to reduce the structural size of the simulation test box 100, and at the same time, the influence of the constant-temperature water bath 200 on the temperature and humidity inside the simulation test box 100 during operation can be avoided.

[0035] In some embodiments, the water inlet hole and the water outlet hole can be located on the opposite side walls of the transparent shell 110. Of course, in other embodiments, the water inlet hole and the water outlet hole can also be arranged at other positions of the transparent shell 110.

[0036] In some embodiments, a water inlet pipe 114 is arranged in the water inlet hole, one end of the water inlet pipe 114 is communicated with the water outlet of the constant-temperature water bath 200, and the other end is communicated with the water inlet of the coating carrier 120. A water outlet pipe 115 is arranged in the water outlet hole, one end of the water outlet pipe 115 is communicated with the water inlet of the constant-temperature water bath 200, and the other end is communicated with the water outlet of the coating carrier 120. In this way, the coating carrier 120 and the constant-temperature water bath 200 can be connected in circulation.

[0037] In some embodiments, the water inlet pipe 114 and the water outlet pipe 115 are flexible pipes or rigid pipes. In the present embodiment, the water inlet pipe 114 and the water outlet pipe 115 are preferably flexible pipes. It should be noted that the water inlet and the water outlet of different coating carriers 120 are arranged at different positions, and the water inlet pipe 114 and the water outlet pipe 115 are flexible pipes, which can facilitate the connection of the water inlets and the water outlets of different coating carriers 120, and help to improve the applicability of the device.

[0038] In some embodiments, the cavity of the coating carrier 120 is used to store cooling water. That is, the coating carrier 120 can be a metal container coated with a coating to be tested, and the coating carrier 120 has a water inlet connected to the cavity, which is used for cooling water to flow into the cavity of the coating carrier 120. As shown in FIG. 1, when the metal container is tested, the metal container with cooling water stored inside is placed in the transparent shell 110, and the cooling water in the metal container can be used to cool the coating to be tested on the surface of the metal container, so that the temperature of the coating to be tested is reduced to below the dew point temperature, thereby realizing condensation, which can simulate the condensation of a part or equipment storing cooling water. It should be noted that the metal container can also be provided with a water outlet, but the water outlet is not opened during the test. Figure 6

[0039] In some embodiments, the coating carrier 120 should be provided with a bearing plane 122 for bearing a sample 121 with a coating to be tested. For example, the coating carrier 120 is a water tank, and the top surface of the water tank forms the bearing plane 122, and the sample 121 with the coating to be tested is placed on the bearing plane 122. In a specific arrangement, the bearing plane 122 can also be provided with a positioning groove 123 for positioning the sample 121.

[0040] In some embodiments, the bearing plane 122 is provided with a weighing module for detecting the weight of the sample 121. For example, the weighing module can be arranged on the bottom surface of the positioning groove 123 or in the groove of the bottom surface of the positioning groove 123. During the test, the weighing module can detect the weight of the sample 121 before and after condensation, so that the weight of condensation can be obtained according to the weight of the sample 121 before and after condensation. It should be noted that in a specific implementation, the weighing module can send the weight information detected by it to the first control panel 160, and the weight information is displayed through the first control panel 160.

[0041] In some embodiments, a plurality of coating carriers 120 are connected between the water inlet end and the water outlet end. For example, a plurality of water pipes are connected between the water inlet end and the water outlet end. In this way, the detection efficiency and accuracy can be improved. In a specific arrangement, the plurality of water pipes can be connected in series between the water inlet hole and the water outlet hole through the joint 116 and the U-shaped pipe 117, or the plurality of coating pipes to be tested can be connected in parallel between the water inlet hole and the water outlet hole through the flow divider and the flow combiner. ​

[0042] In some embodiments, when multiple coating carriers 120 are connected between the water inlet end and the water outlet end, the coating to be tested on each coating carrier 120 can be different from each other. In this way, the dew condensation of different coatings to be tested in the same temperature and humidity environment can be simulated, and the detection efficiency can be improved.

[0043] In some embodiments, the temperature and humidity adjusting module 150 includes a heating module 151 and a humidifying module 152, which are arranged on the inner wall of the transparent shell 110. The heating module 151 is used for heating to adjust the internal temperature of the transparent shell 110, and the humidifying module 152 is used for humidifying to adjust the internal humidity of the transparent shell 110.

[0044] In some embodiments, the first control panel 160 is provided with a temperature and humidity adjusting button 161 and a temperature and humidity display panel 162. The temperature and humidity adjusting button 161 is used to control the adjusting parameters of the temperature and humidity adjusting module 150, including the temperature adjusting parameters (such as 5-40℃) and the humidity adjusting parameters (such as 45-95% RH). The temperature and humidity display panel 162 is used to display the temperature and humidity inside the transparent shell 110. It should be understood that in specific implementations, a detection device (temperature sensor and humidity sensor) connected with the temperature and humidity display panel 162 should be arranged in the transparent shell 110, so that the temperature and humidity display panel 162 can display the temperature and humidity information.

[0045] In some embodiments, the device further includes a video acquisition module arranged in the transparent shell 110, which is used to acquire the video of the formation and development process of the dew condensation on the surface of the coating to be tested. For example, the video acquisition module includes a camera and a signal transmission end. The camera is arranged on the inner side or top of the transparent shell 110, and the signal transmission end is arranged in the transparent shell 110 and electrically connected with the camera. During the test, the camera can shoot the coating carrier 120, so as to acquire the video of the formation and development process of the dew condensation on the surface of the coating to be tested, and the signal transmission end is used to send the shot video to the upper computer or the control end.

[0046] The embodiments of the present application also provide a dynamic environment simulation test method for evaluating the dew condensation resistance performance of a coating, which is suitable for the dynamic environment simulation test device for evaluating the dew condensation resistance performance of a coating as described above, and includes the following steps: Selecting a coating carrier 120 coated with a coating to be tested or arranging a sample 121 with the coating to be tested on the surface of the coating carrier 120; Placing the coating carrier 120 into the transparent shell 110; Arranging the temperature detection device 130 on the surface of the coating carrier 120; Injecting cooling water at a set temperature into the cavity of the coating carrier 120; Start the temperature and humidity adjusting module 150 to adjust the temperature and humidity inside the transparent shell 110 according to the set adjusting parameters. Observe and record the temperature of the surface of the coating carrier 120 and the formation and development process of dew on the surface of the coating carrier 120 or the sample 121.
