Description

Technical Field

[0001] This utility model belongs to the field of material physical property testing or analysis technology, specifically relating to a temperature-controlled superhydrophobic coating water impact resistance tester and a temperature-controlled sample stage. Background Technology

[0002] As a type of coating, the adhesion between superhydrophobic coating and substrate and the stability of the coating itself are crucial to its service life. According to national standards, superhydrophobic coatings need to pass water impact resistance tests to evaluate the stability and reliability of the coating. As a manufacturer, it is also necessary to use water impact resistance tests to provide feedback on the preparation process and adjust the preparation process based on the results to improve the structural strength and adhesion of the superhydrophobic coating.

[0003] Conventional water impact resistance testing devices for superhydrophobic coatings typically consist only of corresponding nozzles and sample stages. For example, Chinese Utility Model Patent CN 222299320 U discloses a "Water Impact Resistance Testing Device for Superhydrophobic Coatings." In this device, the water flow rate is adjusted before the sample is placed on the sample stage. While the structure is relatively simple, operation is cumbersome, requiring experienced operators to maintain high consistency in their actions each time the sample is loaded to eliminate deviations in test results caused by variations in sample condition and height. This type of device is suitable for low-flow-rate, long-duration testing conditions, which can mitigate errors introduced during sample loading. However, if applied to high-flow-rate, short-duration water impact resistance tests, the error in the test results will be too large, and it is also unsuitable for water impact resistance tests on high-temperature samples. Therefore, the applicability of conventional testing devices is currently quite narrow. Utility Model Content

[0004] The primary technical problem to be solved by this invention is to provide a temperature-controlled superhydrophobic coating water impact resistance tester, which addresses the issue of the narrow applicability of conventional superhydrophobic coating water impact resistance testers.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a temperature-controlled superhydrophobic coating water impact resistance tester, including an angle-adjustable sample stage and a water flushing system. The sample stage includes a base, a tray inclined above the base and hinged at one end to the base via a hinge shaft, a support rod hinged at its upper end to the back of the tray, and a first driving component that drives the lower end of the support rod to translate. The translation of the lower end of the support rod causes a change in the inclination of the support rod, thereby adjusting the inclination of the tray. The tray is used to support the sample. The water flushing system includes an interconnected water tank, a water pump, a water supply pipeline, and nozzles corresponding to the sample stage. A temperature controller is installed on the back of the tray, which is sealed to the back of the tray with sealant. A heat-conducting hole is opened on the tray, which is directly opposite the temperature controller. The heat-conducting hole is filled with thermally conductive silicone, which is attached to the temperature controller and is not lower than the upper surface of the tray. The size of the heat-conducting hole is sufficient to allow the entire sample to be completely in contact with the thermally conductive silicone. A protruding baffle is provided on the tray surface below the heat-conducting hole. The base is slidably connected to two tracks, the extension direction of which is parallel to the axis of the hinge. A second drive unit is fixedly installed at one end of each track. The drive end of the second drive unit is connected to the base and is used to drive the base to slide back and forth along the track.

[0006] As a preferred embodiment, guide grooves are provided on both sides of the tray, and the guide grooves extend from the upper edge to the lower edge of the tray along the inclined direction of the tray.

[0007] As a preferred embodiment, a baffle is also hinged to the top of the tray. The baffle is suspended and covers the entire heat conduction hole. A vertically arranged through hole is provided on the baffle. The size and position of the through hole are set according to the water impact test position of the sample. An upwardly extending water-blocking ring is provided around the through hole.

[0008] As a preferred embodiment, the sample stage is housed within a box, which is positioned above a water tank. A drain pipe is connected to the bottom of the box, connecting the box to the water tank. An inlet pipe and an outlet pipe are connected to the water tank, each equipped with an on / off valve. A water pump is located inside the water tank. A water supply pipeline extends from the pump outlet to the top of the water tank, exits the tank, continues upward to the upper part of the box, and then horizontally inserts into the box, suspending it directly above each sample stage. Each nozzle is connected to the water supply pipeline within the box, and each nozzle is equipped with a flow meter and a flow regulating valve. The top of the box is open and detachably connected to a cover plate.

[0009] As a preferred embodiment, the water supply pipeline is equipped with a filter to filter impurities in the water.

[0010] The next technical problem to be solved by this utility model is to provide a temperature-controlled sample stage for the above-mentioned temperature-controlled superhydrophobic coating water impact resistance tester, so as to solve the technical problem that conventional superhydrophobic coating water impact resistance testers have a narrow range of applications and are difficult to use for accurate testing of high-temperature samples.

[0011] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a temperature-controlled sample stage for the above-mentioned temperature-controlled superhydrophobic coating water impact resistance tester, including a base, a tray inclinedly disposed above the base and with one end hinged to the base via a hinge shaft, a support rod with its upper end hinged to the back of the tray, and a first driving component that drives the lower end of the support rod to translate. The translation of the lower end of the support rod causes the tilt angle of the support rod to change, thereby adjusting the tilt angle of the tray. The tray is used to carry the sample. A temperature controller is provided on the back of the tray. The temperature controller is sealed to the back of the tray with sealant. The temperature controller is electrically connected to a power supply and a controller and is controlled by the controller. A heat-conducting hole is opened on the tray, which is directly opposite the temperature controller. The heat-conducting hole is filled with thermally conductive silicone. The thermally conductive silicone is attached to the temperature controller and is not lower than the upper surface of the tray. The size of the heat-conducting hole is sufficient to allow the entire sample to be completely attached to the thermally conductive silicone. A protruding baffle is provided on the surface of the tray below the heat-conducting hole.

[0012] As a preferred embodiment, the temperature controller is fixedly connected to multiple support columns inserted into the heat-conducting holes. The top of each support column is flush with the upper surface of the tray. Thermally conductive silicone is filled between each support column and is flush with the top of each support column. The support columns are made of a metal material with good thermal conductivity, and the tray is made of a material with good thermal insulation properties.

[0013] As a preferred option, the temperature controller is a thermocouple heater, a patch resistance heater, or a circulating condenser.

[0014] The beneficial effects of this invention are as follows: By installing a temperature controller on the back of the tray and utilizing thermally conductive silicone to conduct heat to the sample, the sample can be heated to the target temperature on the sample stage. This eliminates the temperature drop during sample transfer, which leads to large temperature deviations during testing and makes it impossible to accurately detect the water impact resistance of the superhydrophobic coating on the sample surface at a specific temperature. Simultaneously, this invention utilizes a sliding sample stage, allowing the sample to be loaded onto the stage first and then moved to the corresponding nozzle for the water impact resistance test. This ensures consistent sample posture during each water impact resistance test, eliminating detection errors caused by manually loading the sample directly onto the sample stage under the nozzle and improving detection accuracy. Through these improvements, the tester described in this invention is suitable for high-flow-rate, short-duration water impact resistance testing and high-temperature sample water impact resistance testing, expanding the applicability of the tester and improving testing accuracy.

[0016] The specific implementation scheme of this utility model will now be described in detail with reference to the accompanying drawings. Example 1

[0017] like Figures 1-4The present invention discloses a temperature-controlled superhydrophobic coating water impact tester, comprising an angle-adjustable sample stage 1 and a water flushing system 2. The sample stage 1 includes a base 101, a support plate 103 inclined above the base 101 and hinged at one end to the base 101 via a hinge shaft 102, a support rod 104 hinged at its upper end to the back of the support plate 103, and a first driving member 105 for translating the lower end of the support rod 104. In this embodiment, the first driving member 105 is a screw and nut transmission mechanism. The screw 105a of the first driving member 105 is rotatably connected to the base 101, and the lower end of the support rod 104 is hinged to the nut 105b. One end of the screw 105a is connected to a handwheel 105c for adjustment by the operator. The translation of the lower end of the support rod 104 causes the tilt angle of the support rod 104 to change, thereby adjusting the tilt angle of the support plate 103. The support plate 103 is used to support the sample 3. The rinsing system 2 includes an interconnected water tank 201, a water pump 202, a water supply pipe 203, and nozzles 204 corresponding to the sample stage 1. A temperature controller 106 is installed on the back of the tray 103, and the temperature controller 106 is sealed to the back of the tray 103 with sealant. In this embodiment, the temperature controller 106 is an electric heating device such as a thermocouple heater or a patch resistance heater, which can heat the sample 3 to a high temperature. The temperature controller 106 is electrically connected to the power supply 4 and the controller 5, and is controlled by the controller 5. The controller 5 can control the working power of the temperature controller 106, thereby adjusting the target temperature heated by the temperature controller 106. The tray 103 has a heat-conducting hole 107 facing the temperature controller 106. The heat-conducting hole 107 is filled with thermally conductive silicone 108. The thermally conductive silicone 108 is attached to the temperature controller 106 and is not lower than the upper surface of the tray 103. The size of the heat-conducting hole 107 is sufficient to allow the entire sample 3 to be completely attached to the thermally conductive silicone 108, so as to achieve uniform heating of the sample 3 as a whole and eliminate the adverse consequences of local heating of the sample 3 causing changes in internal stress, resulting in a decrease in the strength or adhesion of the superhydrophobic coating structure. The surface of the support plate 103 at the lower edge of the heat conduction hole 107 is provided with a protruding baffle 109 to prevent the sample 3 from sliding down; the base 101 is slidably connected to two tracks 6, the extension direction of the tracks 6 is parallel to the axis of the hinge shaft 102, and a second driving member 7 is fixedly provided at one end of the track 6. The driving end of the second driving member 7 is connected to the base 101 and is used to drive the base 101 to slide back and forth along the track 6. In this embodiment, the second driving member 7 is preferably a cylinder. The cylinder has a fast response speed and can quickly move the workpiece under the nozzle 204, which improves the testing efficiency and reduces the damage caused by the water flow to the sample coating outside the detection area.

[0018] In practical applications, there are many types of temperature controllers 106. Cooling equipment such as circulating condensers can also be used to control the temperature of sample 3. The preferred temperature control range of the circulating condenser is -20℃ to 100℃. When in use, the cold pipes of the circulating condenser are extended to the back of the tray 103, so that the cold pipes are arranged in a serpentine shape and sealed with heat insulation material. The temperature of sample 3 is controlled between -20℃ and 100℃ through the circulating condenser.

[0019] The real-time temperature of sample 3 can be detected using a temperature sensor. Since temperature detection is a conventional technique, it will not be described in this embodiment. The temperature controller 106 itself has target temperature setting and temperature feedback functions. Furthermore, the thermal distance between sample 3 and temperature controller 106 is small, and the thermal conductivity of thermally conductive silicone 108 is high. Therefore, the target temperature of temperature controller 106 is the target temperature of sample 3. When temperature controller 106 reaches the target temperature and maintains it for a period of time, sample 3 will also reach the target temperature.

[0020] like Figure 3 As shown, guide grooves 110 are respectively provided on both sides of the tray 103. The guide grooves 110 extend from the upper edge to the lower edge of the tray 103 along the inclined direction of the tray 103. They are used to guide water droplets splashed on the tray 103 to flow down from the guide grooves 110, reducing the flow of water from both sides of the tray 103 to the back of the tray 103, which could contaminate the temperature controller 106 or cause additional heat dissipation of the temperature controller 106.

[0021] A baffle 111 is also hinged to the top of the support plate 103. The baffle 111 is suspended and covers the entire heat conduction hole 107. A vertically arranged through hole 112 is opened on the baffle 111. The size and position of the through hole 112 are set according to the water impact test position of the sample 3. An upwardly extending water baffle ring 113 is provided around the through hole 112.

[0022] The baffle 111 can block the water flow that impacts the non-detection area during the movement of the sample 3 along with the sample stage 1. When the sample 3 moves into place or is about to move into place, the water flows through the through hole 112 and impacts the detection area of ​​the sample 3, thereby eliminating the problem that the temperature of the sample 3 drops due to the impact of water flow in the non-detection area, which affects the actual temperature of the detection area. The water-blocking ring 113 is used to prevent the water impacting the baffle 111 from spreading into the through hole 112.

[0023] like Figure 1As shown, the sample stage 1 described in this embodiment is housed within a box 8. This design prevents water from splashing everywhere and improves the temperature control of the sample stage 1. The box 8 is positioned above the water tank 201, and a drain pipe 9 is connected to the bottom of the box 8. The drain pipe 9 connects the box 8 to the water tank 201. Water flowing from the nozzle 204 impacts the sample 3 and then flows back into the water tank 201 through the drain pipe 9. The water tank 201 is connected to an inlet pipe 10 and an outlet pipe 11, each equipped with an on / off valve 12. After a period of use, the water in the water tank 201 needs to be replaced. The water is drained through the outlet pipe 11, and new test water is added through the inlet pipe 10. A water pump 202 is installed inside a water tank 201. A water supply pipe 203 extends from the outlet of the water pump 202 to the top of the water tank 201, then exits the water tank 201 and continues upward to the upper part of the housing 8. It is then horizontally inserted into the housing 8 and suspended directly above each sample stage 1. Each nozzle 204 is connected to the water supply pipe 203 inside the housing 8. Each nozzle 204 is connected to a flow meter 205 and a flow regulating valve 206. The flow meter 205 provides feedback to the user on the actual flow rate, flow velocity, and other fluid parameters of the nozzle 204. The flow regulating valve 206 allows the user to adjust the water flow velocity from the nozzle 204. The top of the housing 8 is open and detachably connected to a cover plate 13. The user can adjust the flow regulating valve 206 of the nozzle 204 by opening the cover plate 13.

[0024] In order to eliminate the influence of the gradually increasing impurities in the water on the water impact resistance test, this embodiment preferably provides a filter 207 on the water supply pipeline 203 to filter impurities in the water.

[0025] For details of the specific working process of this embodiment, please refer to Embodiment 2. Example 2

[0026] The method for testing the water impact resistance of superhydrophobic coatings, using the temperature-controlled superhydrophobic coating water impact resistance tester described in Example 1 above, includes the following specific steps: S1. Control the second driving component 7 to drive the sample stage 1 away from the corresponding nozzle 204 and load the sample 3 onto the tray 103 of the sample stage 1.

[0027] S2. Start the flushing system 2 of the temperature-controlled superhydrophobic coating water impact tester, adjust the water flow rate output by the nozzle 204 to the target speed, and wait for the water flow to stabilize.

[0028] S3. After the water flow rate output by the nozzle 204 stabilizes, control the second driving component 7 to drive the sample stage 1 to reset. The sample stage 1 drives the sample 3 to move below the corresponding nozzle 204, and the water flow performs a water impact resistance test on the sample 3.

[0029] S4. After the water flow impacts the sample 3 for a specific duration, the nozzle 204 is closed or the second driving component 7 is controlled to drive the sample stage 1 away from the corresponding nozzle 204, the sample is removed, the hydrophobic properties of the sample are tested, and the water impact resistance is determined based on the test results.

[0030] If a water impact resistance test is required for sample 3 at high temperature, the temperature controller 106 is activated to heat sample 3 while performing step S2. After heating sample 3 to the target temperature, step S3 is performed.

[0031] If it is necessary to test the low-temperature anti-icing performance of sample 3, then while performing step S2, start the temperature controller 106 to cool sample 3 to below zero degrees, such as -15°C, and then perform step S3 to test the anti-icing performance of the superhydrophobic coating at low temperature.

[0032] To ensure the accuracy of the high-temperature water impact resistance test of sample 3, a baffle 111 is placed on the sample stage 1 after sample 3 is loaded onto it in step S1. This prevents the water jet from the nozzle 204 from spraying outside the test area during step S3, thus avoiding water impact on sample 3 outside the test area and causing a drop in temperature in the test area. Example 3

[0033] like Figures 2-4 The temperature-controlled sample stage shown is used in the temperature-controlled superhydrophobic coating water impact tester described in Example 1. It includes a base 101, a support plate 103 inclined above the base 101 with one end hinged to the base 101 via a hinge shaft 102, a support rod 104 with its upper end hinged to the back of the support plate 103, and a first driving member 105 that drives the lower end of the support rod 104 to translate. The translation of the lower end of the support rod 104 causes a change in the inclination of the support rod 104, thereby adjusting the inclination of the support plate 103. The support plate 103 is used to support the sample. The characteristic feature is that a [missing information - likely a design element] is provided on the back of the support plate 103. A temperature controller 106 is sealed to the back of the tray 103 with sealant. The temperature controller 106 is electrically connected to the power supply 4 and the controller 5 and is controlled by the controller 5. A heat-conducting hole 107 is opened on the tray 103, which is directly opposite the temperature controller 106. The heat-conducting hole 107 is filled with thermally conductive silicone 108. The thermally conductive silicone 108 is attached to the temperature controller 106 and is not lower than the upper surface of the tray 103. The size of the heat-conducting hole 107 is sufficient to allow the entire sample 3 to be completely attached to the thermally conductive silicone 108. A protruding baffle 109 is provided on the surface of the tray 103 below the heat-conducting hole 107.

[0034] Since the thermally conductive silicone 108 has a certain degree of elasticity, in order to eliminate the impact of the elasticity of the thermally conductive silicone 108 on the accuracy of the water impact resistance test of the superhydrophobic coating, this embodiment has a number of rigid support columns 114 fixedly connected to the temperature controller 106 and inserted into the thermally conductive holes 107. The top of each support column 114 is flush with the upper surface of the support plate 103. The thermally conductive silicone 108 is filled between each support column 114 and is flush with the top of each support column 114. The support columns 114 are made of metal materials with good thermal conductivity, and the support plate 103 is made of materials with good thermal insulation properties.

[0035] The support column provides good support for sample 3 without affecting the thermal conductivity of the thermally conductive silicone 108 to sample 3, thus ensuring the heating effect of the temperature controller 106 on sample 3.

[0036] In practical applications, the use of support column 114 can be selected according to needs. For example, when the water flow velocity of nozzle 204 is unstable and pulsating, not using support column 114 can improve detection accuracy. The elasticity of thermally conductive silicone 108 can absorb the detection error caused by the water flow pulsation. However, when the water flow velocity of nozzle 204 is stable, it is better to use support column 114.

[0037] The temperature controller 106 preferably uses electric heating equipment such as thermocouple heaters, surface mount resistance heaters, or circulating condensers, which have a wider temperature adjustment range.

[0038] The above embodiments are merely illustrative of the principles and effects of the present invention, as well as some examples of its application, and are not intended to limit the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the inventive concept of the present invention, and these modifications and improvements are all within the scope of protection of the present invention.
