Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of anti-permeability detection, specifically to an anti-permeability detection device for nanometer waterproof coating. BACKGROUND

[0002] In the current era of rapid technological advancement, nanotechnology is continuously expanding the boundaries of material applications, and nanometer waterproof coating is a prominent representative among them. Nanometer waterproof coating, as the name suggests, is a coating material with excellent waterproof performance based on nanotechnology. Its microstructure presents a unique nanoscale structure, and this fine structure endows the coating with many excellent properties. Compared with traditional waterproof coatings, nanometer waterproof coating is extremely thin, usually in the nanometer scale, but can exhibit extraordinary waterproof effect. This is due to its special surface microtopography, which makes water droplets on the coating surface roll like on a lotus leaf, showing a very low contact angle, greatly reducing the wetting degree of water and the surface of the coated object, thereby effectively preventing water penetration.

[0003] Nanometer waterproof coating has shown broad application prospects in the field of waterproof parts for electronic products and large devices. In the field of electronic products, with the popularity of smartphones, tablets, smartwatches and other devices, consumers' demand for waterproof performance is increasing. Taking smartphones as an example, nanometer waterproof coating can be uniformly coated on the surfaces of key components such as the motherboard, chips and batteries inside the smartphone, forming an invisible protective barrier. This not only prevents damage to electronic components caused by accidental water splashing or moisture during daily use, prolonging the service life of the smartphone, but also improves the overall reliability of the smartphone to some extent. In some high-end smartphones, nanometer waterproof coating has become a standard, providing users with a more secure user experience.

[0004] In the field of wearable devices, nanometer waterproof coating also plays an important role. Smartwatches, fitness bands and other devices need to be in contact with the human body at all times and are easily eroded by liquids such as sweat and rain. Nanometer waterproof coating can effectively resist the penetration of these liquids, ensuring the normal operation of the internal electronic components of the device, while also avoiding appearance damage and wearing discomfort caused by liquid erosion. In addition, in small audio devices such as earphones and Bluetooth speakers, the application of nanometer waterproof coating can prevent water from entering, ensure sound quality and prolong the service life of the device.

[0005] In the waterproof parts of large devices, the application of nano waterproof coating is also very extensive. For example, in the field of aerospace, many key components of aircraft, such as electronic devices and sensors inside the engine compartment, need to work normally under complex weather conditions. Nano waterproof coating can provide reliable waterproof protection for these components to prevent failures caused by the intrusion of rain, high-altitude condensate and other liquids, and ensure flight safety. In automobile manufacturing, waterproofing of automobile engines, electronic control systems and other parts is crucial. Nano waterproof coating can be applied to sensors, vehicle computers and other parts of the car to effectively improve the reliability of the car in rainy or humid environments and reduce the risk of water-induced failures.

[0006] However, although nano waterproof coating has great potential in many fields, there are many problems in the detection of its waterproof performance. Currently, there is no clear quantitative index for the waterproof performance of nano waterproof coating. The existing detection methods are often based on the detection of the overall product after application. For example, for a mobile phone that has applied nano waterproof coating, its waterproof performance is detected according to the "Protection Level" standard, which mainly starts from the overall protection of the product and assesses the protection ability of the mobile phone under different levels of water contact. However, it is difficult to accurately measure the waterproof efficiency of nano waterproof coating. Similarly, nano waterproof coating applied to washing machines is detected by "Special Requirements for Safety of Household and Similar Use Electric Washing Machines", which focuses on the waterproof safety performance of the washing machine as a whole during use, and cannot accurately evaluate the waterproof performance of nano waterproof coating. Because different products use different detection specification requirements and indicators, the detection of the waterproof performance of nano waterproof coating is complicated and not unified. This not only brings great difficulties to the research and development and quality control of nano waterproof coating, but also makes it difficult for consumers to accurately judge the actual performance of nano waterproof coating when choosing related products, which seriously hinders the further development and wide application of nano waterproof coating technology.

[0052] Working principle: The main body of the device is the device shell 1, which is like a solid fortress that houses and protects the internal key components. On the device shell 1, there are six groups of anti-permeation detectors 4 evenly distributed, which are the core execution units of the entire detection process. Inside the device shell 1, the water tank 6 is like a "water reserve" that stores a large amount of water needed for detection, while the controller is like the "brain" of the device, directing the coordinated work of each component. Before detection, a series of preparations must be made. The operator injects a sufficient amount of water into the water tank 6 through the water inlet 2, which will be used as the subsequent detection of the permeation liquid. It is worth noting that the device is equipped with a drain at the bottom, which must be used to drain the residual water inside during the device downtime to prevent damage to the device caused by liquid residue. At the same time, standard substrates 12 with nano waterproof coating are installed on the anti-permeation detectors 4. The six groups of standard substrates 12 are designed with precision, two of which are coated with nano waterproof coating on both sides, and four of which are coated with nano waterproof coating on one side. When installing, the two groups of standard substrates 12 with nano waterproof coating on one side are installed with the side with nano waterproof coating facing up, and the other two groups are installed with the side with nano waterproof coating facing down, which fully covers the single-sided positive and negative and double-sided pressure conditions that may be encountered in actual applications, laying the foundation for comprehensive detection of anti-permeation performance. The circular edge of the standard substrate 12 is covered with sealing material to ensure that the entire system is well sealed during the detection process to avoid side penetration. The support plate 10 in the installation pipe 7 has a water penetration hole 11 in the center, and one side of the standard substrate 12 is tightly pressed against the support plate 10, providing stable support and water penetration channel for subsequent permeation detection. Finally, the standard substrate 12 is firmly pressed into the installation pipe 7 using the pressing plate 5, further ensuring the stability of the standard substrate 12 during the detection process. When everything is ready, the detection work officially begins. The anti-permeation detector 4 is composed of the installation pipe 7, the working cavity 8, and the booster pipeline 9. The water in the water tank 6 flows through the booster main pipeline 16 to the six booster pipelines 9 under the action of the high-pressure liquid pump 15, and then enters the working cavity 8. At this time, the working cavity 8 is filled with a certain amount of water, which plays a key role as the permeation liquid in the subsequent detection. The electrically controlled gate valve 13 and the pressure sensor 14 installed on the booster pipeline 9 are the "intelligent eyes" and "control valves" in the detection process. The pressure sensor 14 monitors the pressure of the liquid in the pipeline in real time, and the electrically controlled gate valve 13 can close the pipeline to maintain a constant pressure in the working cavity 8. At the beginning of the detection, a lower water pressure is set as the initial detection pressure. Through the pressure data feedback of the pressure sensor 14, the controller accurately controls the working state of the high-pressure liquid pump 15 to ensure that the water pressure is stable at the set value. Under this pressure, the water in the working cavity 8 exerts pressure on the standard substrate 12 through the water penetration hole 11 on the support plate 10. If the liquid seeps out of the upper surface of the standard substrate 12, it is undoubtedly a clear signal that the standard substrate 12 fails to resist permeation under this water pressure.Conversely, if the standard substrate 12 does not appear to have a penetration leakage phenomenon within the preset quantitative time, it means that it meets the current penetration resistance level. At this time, the operator can issue an instruction through the controller to open the electrically controlled gate valve 13 and start the high-pressure liquid pump 15 again. The high-pressure liquid pump 15 will continuously input more liquid into the working cavity 8 through the booster main pipeline 16 and the booster pipeline 9, gradually increasing the water pressure, and entering the detection of the next penetration resistance level. This cycle continues until the standard substrate 12 appears to have a penetration phenomenon, and the maximum water pressure value that can be withstood corresponds to the maximum penetration resistance level of the nano waterproof coating. The device realizes omnidirectional detection of the penetration resistance of the nano waterproof coating by virtue of the six groups of penetration resistance detectors 4 and the diversified installation methods of the standard substrate 12. For the standard substrate 12 with a single-sided nano waterproof coating, different installation directions (coating facing up or down) can simulate the penetration resistance performance of the coating when facing different directions of water pressure in actual application scenarios. The standard substrate 12 with a double-sided nano waterproof coating is specially used to detect the penetration resistance of the coating under double-sided pressure, fully meeting the stringent requirements of various complex actual application environments for the penetration resistance performance detection of the nano waterproof coating. At the same time, by taking water pressure as a variable and dividing it into different gradients for phased detection, the penetration resistance level of the nano waterproof coating can be determined very accurately, providing solid and reliable data support for the performance evaluation of the nano waterproof coating in actual applications.

[0053] Although the embodiments of the present application have been shown and described, it should be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
