Description

Technical Field

[0001] This invention relates to the field of material defect detection technology, specifically to a novel conductive and thermally conductive material defect detection device and method with a layered structure. Background Technology

[0002] With the rapid development of electronic technology, the requirements for material performance in highly integrated electronic modules are becoming increasingly stringent. Composite tapes, possessing light-shielding, conductivity, and EMI (electromagnetic interference) shielding properties, are showing great application potential in the field of highly integrated electronic modules as a novel material. This composite tape employs a special laminated structure of a light-shielding coating and conductive filler, which significantly improves the integrated EMI / light-shielding performance. It is not only suitable for optoelectronic and radio frequency modules but also possesses the significant advantage of "one tape, multiple uses," effectively reducing the number of material layers and assembly costs, and providing strong support for the development of thinner, lighter, and higher-performance electronic products.

[0003] However, in actual production and application, the quality stability of composite tapes is crucial. Due to various factors such as production processes, transportation, and storage, defects may appear on the surface of composite tapes, such as scratches, stains, and uneven coatings. These defects can severely affect their light-shielding, conductivity, and EMI shielding performance, thereby reducing the overall performance and reliability of highly integrated electronic modules. Therefore, accurate and efficient defect detection of composite tapes is a key step in ensuring product quality.

[0004] Currently, in the existing technology for testing composite tapes, contaminants such as grease and dust easily adhere to the surface of the composite tape. These contaminants can interfere with the detection signal, reduce the accuracy of the detection, and lead to inaccurate test results that cannot truly reflect the actual quality of the composite tape. Therefore, a novel conductive and thermally conductive material defect detection device and method with a layered structure is proposed. Summary of the Invention

The two ends of the wiping cloth are provided with second hook and loop fasteners, and two second hook and loop fasteners are correspondingly connected. Based on the matching arrangement between the first hook and loop fasteners and the second hook and loop fasteners, it is convenient for the staff to disassemble and replace the wiping cloth.

[0013] Preferably: the end of the telescopic spring away from the limiting groove is connected to the outer wall of the sliding magnet, and the telescopic spring is sleeved on the outer wall of the limiting crossbar.

Multiple guide plates are fixedly connected to the top two sides of the detection platform.

[0015] This invention also discloses a detection method for a novel conductive and thermally conductive material defect detection device with a layered structure, the method comprising the following steps: S1: First, connect the composite tape to the drive tensioning mechanism, and then start the drive tensioning mechanism to perform a tensioning operation on the composite tape. This will make the installed composite tape taut, allowing it to effectively rub and clean against the wiping cloth on the outer wall of the friction roller while in a taut state. S2: Turn on the servo motor to rotate and pull the composite tape to wind it up, so that the composite tape can be inspected by the defect detection mechanism. S3: When performing defect detection on composite tape, the outer wall of the tape slides and adheres to the wiping cloth, allowing the wiping cloth to rub and clean the outer wall of the composite tape to be tested, removing grease, dust and other contaminants, thus improving the detection effect of the defect detection instrument on the outer wall of the composite tape. S4: When rubbing and cleaning the outer wall of the composite tape, the wiping cloth can be wetted according to the function of the wetting and cleaning mechanism. The wetted wiping cloth increases the cleaning effect of rubbing and cleaning the outer wall of the composite tape. The mixture of alcohol and grease cleaner is an organic solvent that can effectively dissolve grease, dust and other pollutants. It is also highly volatile and leaves little residue, making it easy to rub and clean the outer surface of the composite tape.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. By setting up a wetting and cleaning mechanism, the outer surface of the composite tape can be effectively cleaned during the traction and winding inspection of the composite tape. The wiping cloth on the outer wall of the friction roller can rub and clean grease, dust, and other contaminants from the outer wall of the composite tape, improving the detection effect of the defect detector on the outer wall of the composite tape and ensuring accurate and reliable test results, providing high-quality assurance for subsequent applications such as highly integrated electronic modules. At the same time, during the wetting and cleaning process of the outer surface of the composite tape, the drive shaft drives the arc plate to stir the mixture of alcohol and grease cleaning agent inside the storage tank. Based on the function of the flow hole, the flow effect of the arc plate on the stirring of the mixture of alcohol and grease cleaning agent is increased, thereby improving the efficiency of the mixture after stirring. The improved performance enhances the cleaning effect of the alcohol and grease cleaner mixture on the outer surface of the composite tape. The sliding magnetic block, under the combined action of the fixed magnetic block and the telescopic spring, slides intermittently, causing the sliding plate to correspondingly squeeze air into the air outlet chamber, increasing airflow and accelerating the evaporation of the alcohol and grease cleaner mixture. This prevents residue from affecting the detection results. Furthermore, the intermittent sliding of the magnetic block causes alcohol to flow intermittently onto the wiping cloth, increasing the cleaning effect of the wiping cloth on the outer wall of the composite tape while reducing the consumption of the alcohol and grease cleaner mixture. This prevents excessive alcohol and grease cleaner mixture from adhering to the outer wall of the wiping cloth and forming water droplets, which could affect the detection results of the composite tape.

[0017] By driving the tensioning mechanism, the installed composite tape can be taut, allowing it to effectively rub against the wiping cloth for cleaning, thus ensuring the cleaning effect. On the other hand, before the composite tape is inspected for defects, its tension strength can be tested. This allows staff to directly inspect the composite tape for defects after completing the tension strength test, without the need for additional complicated operations, thus improving the coordination and overall efficiency of the inspection process. After the composite tape passes through the tensioning mechanism and the tension detection operation is completed, the servo motor is turned on, which drives the second rotating rod and the traction roller to rotate and rewind the composite tape. When the composite tape is in a tensioned state, its outer wall slides against the wiping cloth on the outer wall of the friction roller, ensuring the continuous cleaning work during the traction and rewinding process. The whole process is smooth and efficient. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1: Please refer to Figures 1-8 It includes multiple support legs 1, a detection platform 29 mounted on top of the multiple support legs 1, and composite tape 14, and also includes: The defect detection mechanism is used to detect defects on the outer wall of the composite tape 14. The defect detection mechanism is set above the detection platform 29. The defect detection mechanism includes a first square frame 2 installed above the detection platform 29. A defect detector 3 is fixedly installed on the bottom of the inner wall of the first square frame 2. A data display screen 4 is installed on one side of the outer wall of the first square frame 2. The defect detector 3 and the data display screen 4 are connected by a signal. The data display screen 4 is used to display the data after the defect detector 3 detects defects in the composite tape 14. This is the prior art, and its working principle will not be described in detail. The drive tensioning mechanism is used to tighten the installed composite tape 14. On one hand, it ensures the composite tape 14 is taut, allowing for effective friction cleaning between the tape and the wiping cloth 19 on the outer wall of the friction roller 18. On the other hand, it allows for tension testing of the composite tape 14 before defect detection, facilitating defect detection after the tension strength test. The drive tensioning mechanism is located on one side of the testing platform 29 and includes a mounting box 5 with multiple fixing plates 9 and multiple mounting plates 11 mounted on one side of the outer wall of the testing platform 29. A drive motor 6 is fixedly mounted on one side of the outer wall of the mounting box 5. A threaded rod 7 is fixedly connected to the output end of the drive motor 6, and the end of the threaded rod 7 away from the drive motor 6 extends rotatably into the interior of the mounting box 5. A limit plate 28 is fixedly connected inside the mounting box 5. A moving block 8 is threadedly connected to the outer wall of the threaded rod 7 between the limit plate 28 and the mounting box 5. A fixed plate 9 is fixedly installed above the moving block 8. A first rotating rod 12 and a second rotating rod 30 are rotatably connected between the two sets of fixed plates 9 and the mounting plate 11, respectively. A rotating roller 13 and a traction roller 36 are fixedly connected between the first rotating rod 12 and the second rotating rod 30, respectively. A servo motor 10 is fixedly connected to the outer side of one of the fixed plates 9, and one end of the second rotating rod 30 is fixedly connected to the output end of the servo motor 10.

[0022] The present invention is further described in detail as follows: the outer side wall of the movable block 8 and the inner side wall of the mounting box 5 are slidably fitted together; the outer side wall of the threaded rod 7 is provided with a threaded groove between the limiting plate 28 and the mounting box 5, and the two threaded grooves are arranged in opposite directions; the composite tape 14 is disposed between the rotating roller 13 and the traction roller 36. The present invention is further described in detail. A connecting plate 33 is fixedly connected between multiple support legs 1. The multiple connecting plates 33 are arranged in a square frame. A connecting horizontal plate 34 is fixedly connected between two parallel connecting plates 33. A vertically arranged support plate 35 is fixedly connected between the connecting horizontal plate 34 and the detection platform 29. Through the cooperation between the connecting plates 33, the connecting horizontal plate 34 and the support plate 35, the connection strength of the bottom of the detection platform 29 supported by the support legs 1 is enhanced. In this embodiment, the two ends of the composite tape 14 are first connected between the rotating roller 13 and the traction roller 36, respectively. Then, the drive motor 6 is started to drive the threaded rod 7 to rotate. Based on the opposite arrangement of the two threaded grooves, the distance between the rotating roller 13 and the traction roller 36 can be increased, which can tighten the composite tape 14. On the one hand, the composite tape 14 is in a taut state after installation, so that the composite tape 14 can effectively rub and clean against the wiping cloth 19 on the outer wall of the friction roller 18 in the taut state. On the other hand, before the composite tape 14 is inspected for defects, the tension of the composite tape 14 can be tested for tension strength, which makes it convenient for the staff to inspect the composite tape 14 for defects after the tension strength test. It should be noted that: In the initial state, the distance between the rotating roller 13 and the traction roller 36 is small, so that the composite tape 14 installed between the rotating roller 13 and the traction roller 36 is not in a taut state, which makes it easier for the staff to connect the composite tape 14 and connect the two ends of the composite tape 14 between the rotating roller 13 and the traction roller 36 respectively. This is the prior art, and its working principle will not be described in detail. It should be noted that when the composite tape 14 is in a taut state, its outer wall and the wiping cloth 19 on the outer wall of the friction roller 18 are slidably attached. Based on the function of the composite tape 14 being taut, it is convenient for the staff to effectively slide and attach the outer wall of the composite tape 14 to the outer wall of the wiping cloth 19. Specifically, tension sensors are provided on both the first rotating rod 12 and the second rotating rod 30. The tension sensors are connected to the data display screen 4 for signal transmission, and the data of the tension strength detection is displayed on the data display screen 4. The first rotating rod 12 is the initial contact point when the composite tape 14 is tightened. The tension sensor at this position can directly measure the initial tension of the composite tape 14 during the tightening process, reflecting the force applied by the tightening mechanism. The second rotating rod 30 is the terminal contact point of the composite tape 14 when it is wound up; it measures the actual tension of the composite tape 14 during the winding process, reflecting the combined effect of tensioning and winding. By setting up the above technical solution and driving the tensioning mechanism, on the one hand, the installed composite tape 14 can be in a tensioned state, allowing the composite tape 14 to effectively rub and clean with the wiping cloth 19 in the tensioned state, ensuring the cleaning effect; on the other hand, before the composite tape 14 is inspected for defects, a tension test can be performed on it, which makes it convenient for staff to directly inspect the composite tape 14 for defects after completing the tension strength test, without the need for additional complicated operations, thus improving the coordination and overall efficiency of the inspection process. Multiple support legs 1 are connected to each other through connecting plates 33, connecting cross plates 34 and support plates 35, forming a square frame. This enhances the connection strength of the bottom of the detection platform 29 supported by the support legs 1, making the entire device more stable and reliable during operation and reducing the impact of vibration and other factors on the detection results. In the drive tensioning mechanism, the drive motor 6 drives the threaded rod 7 to rotate. By using two oppositely arranged threaded grooves, the distance between the rotating roller 13 and the traction roller 36 can be flexibly increased or decreased, which makes it convenient for the staff to perform tensioning or connection operations on the composite tape 14 according to the actual situation. The smaller distance setting in the initial state also facilitates the connection of the composite tape 14, improving the convenience and flexibility of operation. After the composite tape 14 completes the tensioning detection operation through the driving tensioning mechanism, the servo motor 10 is turned on, which drives the second rotating rod 30 and the traction roller 36 to rotate, thereby realizing the rotational traction and winding of the composite tape 14. When the composite tape 14 is in a tensioned state, its outer wall slides and adheres to the wiping cloth 19 on the outer wall of the friction roller 18, ensuring the continuous cleaning work during the traction and winding process. The whole process is smooth and efficient.

[0023] Example 2: Please refer to Figures 1-8 This embodiment further describes Example 1. The wetting and cleaning mechanism is used to clean the outer wall of the composite tape 14 when it is being tested, thereby increasing the accuracy of the test. The wetting and cleaning mechanism is set above the test platform 29. The wetting and cleaning mechanism includes a plurality of second square frames 15 installed above the test platform 29. A storage tank 16 is fixedly connected to one side of the inner wall of the second square frame 15. A connecting shaft 17 is rotatably connected between the two sides of the inner wall of the second square frame 15. A friction roller 18 is fixedly connected to the outer wall of the connecting shaft 17. A wiping cloth 19 is provided on the outer wall of the friction roller 18. The wetting and cleaning mechanism also includes a drive shaft 20 rotatably connected inside the storage tank 16, with one end of the drive shaft 20 extending rotatably to the outside of the storage tank 16. Multiple arc-shaped plates 37 are fixedly connected to the outer wall of the drive shaft 20. An air outlet box 21 is fixedly connected to one side of the outer wall of the storage tank 16. An air outlet mesh plate 27 communicating with the outside is connected to the bottom of the air outlet box 21. The air outlet mesh plate 27 is inclined. A limiting groove 22 is opened at the bottom of the inner wall of the storage tank 16. A limiting crossbar 23 is fixedly connected inside the limiting groove 22. A sliding magnet 24 is slidably connected to the outer wall of the limiting crossbar 23. A sliding rod 25 is fixedly connected to one side of the sliding magnet 24. A telescopic spring 38 is fixedly connected to one side of the inner wall of the limiting groove 22. The telescopic spring 38 is arranged along the length direction of the limiting crossbar 23. A sliding plate 26 is fixedly connected to the end of the sliding rod 25 away from the sliding magnet 24.

[0024] The present invention is further described in detail as follows: multiple arc-shaped plates 37 are located inside the storage tank 16, and multiple flow holes are opened on the outer walls of the multiple arc-shaped plates 37; a sliding plate 26 is located inside the air outlet box 21; the outer wall of the sliding magnet 24 and the inner wall of the limiting slide groove 22 are slidably fitted together; the outer wall of the friction roller 18 and the inner wall of the wiping cloth 19 are both provided with first hook and loop fasteners, and the two first hook and loop fasteners are connected in a corresponding manner; the two ends of the wiping cloth 19 are provided with second hook and loop fasteners, and the two second hook and loop fasteners are connected in a corresponding manner; based on the cooperation between the first hook and loop fasteners and the second hook and loop fasteners, it is convenient for the staff to disassemble and replace the wiping cloth 19.

[0025] The invention is further described in detail as follows: the end of the telescopic spring 38 away from the limiting groove 22 is connected to the outer wall of the sliding magnetic block 24, and the telescopic spring 38 is sleeved on the outer wall of the limiting crossbar 23. The end of the arc plate 37 is fixedly connected to a fixed magnetic block. The fixed magnetic block and the sliding magnetic block 24 are arranged to attract each other with opposite poles. The bottom of the sliding magnetic block 24 is provided with a dispensing hole, and the dispensing hole is arranged to correspond with the wiping cloth 19. The top of the outer walls of the storage tank 16 and the air outlet tank 21 are respectively provided with a dispensing hole and an air inlet hole. The air inlet hole and the air outlet mesh plate 27 are respectively located on both sides of the sliding plate 26. The outer side wall of the sliding plate 26 and the inner side wall of the air outlet tank 21 are slidably fitted. The outer side walls of the connecting shaft 17 and the transmission shaft 20 are both fixedly connected to two limiting discs 31. The connecting shaft 17 and the transmission shaft 20 are connected by a transmission belt 32. The transmission belt 32 is located between the two limiting discs 31. Multiple guide plates 39 are fixedly connected to the top two sides of the detection platform 29. In this embodiment, after the composite tape 14 completes the tensioning detection operation through the driving tensioning mechanism, the servo motor 10 is turned on, which drives the second rotating rod 30 to rotate, and correspondingly drives the traction roller 36 to rotate, thereby rotating and pulling the composite tape 14 to wind it up. When the composite tape 14 is pulled and wound, its outer wall slides and adheres to the wiping cloth 19, which allows the wiping cloth 19 to rub and clean the outer wall of the composite tape 14 to be tested, and to clean the outer wall of the tape, removing grease, dust and other contaminants, thereby improving the detection effect of the defect detector 3 on the outer wall of the composite tape 14. It should be noted that when the composite tape 14 is in a taut state, the two sides of the outer wall of the composite tape 14 are attached to one side of the guide plate 39. In this state, the composite tape 14 is prevented from deviating when it is pulled and wound up. When the friction roller 18 rotates, the transmission belt 32 drives the transmission shaft 20 to rotate, which in turn drives the arc plate 37 to stir the mixture of alcohol and grease cleaning agent inside the storage tank 16. The flow holes further enhance the flow effect of the arc plate 37 on the alcohol and grease cleaning agent mixture, thus improving its usability. When the fixed magnetic block at the end of the arc plate 37 corresponds to the sliding magnetic block 24, the attraction between their opposite poles allows the sliding magnetic block 24 to slide inside the limiting groove 22 as the arc plate 37 rotates. As the sliding magnetic block 24 slides, it drives the sliding rod 25 and the sliding plate 26 to move. When the moving plate 26 slides inside the air outlet box 21, it can draw in air through the air outlet mesh plate 27. When the fixed magnetic block at the end of the arc plate 37 separates from the sliding magnetic block 24, the sliding magnetic block 24 can return to its initial position according to the elastic extension and contraction of the extension spring 38, so that the sliding magnetic block 24 can perform intermittent sliding operation. The sliding plate 26 can slide and squeeze the air inside the air outlet box 21. The gas is discharged through the air outlet mesh plate 27, which increases the air circulation below the air outlet box 21 and increases the evaporation effect of the mixture of alcohol and grease cleaning agent on the composite tape 14. It avoids the residue of the mixture of alcohol and grease cleaning agent affecting the detection effect of the defect detector 3 on the composite tape 14. It should be noted that the tilting direction of the air outlet plate 27 is the same as the traction direction of the composite tape 14. Based on the tilting air blowing effect of the air outlet plate 27, the airflow is prevented from blowing directly onto the not completely dry composite tape 14, which would cause the mixture of alcohol and grease cleaning agent droplets to spread and increase residue. The air outlet plate 27 only accelerates the air circulation around the composite tape 14, which can effectively blow away the grease cleaning agent mixed with alcohol. It should be noted that: the bottom of the storage tank 16 is provided with a guide groove, and the guide groove is connected to the interior of the dispensing hole. The length of the guide groove is adapted to the length of the friction roller 18, so that the mixture of alcohol and grease cleaner can enter the interior of the guide groove through the dispensing hole and evenly wet the wiping cloth 19 on the outer wall of the friction roller 18. When the sliding magnetic block 24 slides, the dispensing hole at its bottom aligns with the guide channel of the alcohol and grease cleaning agent mixture at the bottom of the storage tank 16. The alcohol and grease cleaning agent mixture can flow through the guide channel to the outer wall of the wiping cloth 19, wetting the wiping cloth 19. The wetted wiping cloth 19 increases the cleaning effect of friction cleaning on the outer wall of the composite tape 14. The alcohol and grease cleaning agent mixture is an organic solvent that can effectively dissolve pollutants such as grease and dust. It is also highly volatile and leaves little residue, making it easy to friction clean the outer surface of the composite tape 14. By intermittently sliding the sliding magnetic block 24, the mixture of alcohol and grease cleaning agent can be intermittently discharged. On the one hand, this reduces the consumption of the mixture of alcohol and grease cleaning agent, and on the other hand, it prevents excessive mixture of alcohol and grease cleaning agent from adhering to the outer wall of the wiping cloth 19. This causes water droplets of the mixture of alcohol and grease cleaning agent to adhere to the outer wall of the composite tape 14, resulting in slower evaporation and affecting the detection effect of the defect detector 3 on the composite tape 14. It should be noted that the magnetic attraction between the fixed magnetic block and the sliding magnetic block 24, where opposite poles attract each other, matches the elastic coefficient of the extension spring 38, which enables the fixed magnetic block to effectively drive the sliding magnetic block 24 to slide. As the composite tape 14 is continuously cleaned and wound up, according to the corresponding function of the composite tape 14 and the defect detector 3, the defect detector 3 can detect the composite tape 14. The defect detector 3 and the data display screen 4 are connected by a signal. The data display screen 4 is used to display the data after the defect detector 3 detects the defects in the composite tape 14. This is the prior art, and its working principle will not be described in detail. By setting up the above technical solution and by setting up a wetting and cleaning mechanism, the outer surface of the composite tape 14 can be effectively cleaned when the composite tape 14 is being pulled and wound for inspection; the wiping cloth 19 on the outer wall of the friction roller 18 can rub and clean the grease, dust and other contaminants on the outer wall of the composite tape 14, improve the inspection effect of the defect detector 3 on the outer wall of the composite tape 14, ensure the accuracy and reliability of the inspection results, and provide high-quality assurance for subsequent applications such as highly integrated electronic modules; Simultaneously, during the wetting and cleaning process of the outer surface of the composite tape 14, the drive shaft 20 drives the arc plate 37 to stir the mixture of alcohol and grease cleaner inside the storage tank 16, making the mixture of alcohol and grease cleaner more effective and increasing the cleaning effect of the mixture of alcohol and grease cleaner on the grease on the outer surface of the composite tape 14. The sliding magnetic block 24 slides intermittently under the combined action of the fixed magnetic block and the telescopic spring 38, and the sliding plate 26 correspondingly slides and squeezes air inside the air outlet 21 to increase air circulation, accelerate the evaporation of the mixture of alcohol and grease cleaner, and avoid the residue of the mixture of alcohol and grease cleaner affecting the detection effect. At the same time, the intermittent sliding of the sliding magnetic block 24 causes the mixture of alcohol and grease cleaner to flow out intermittently to the wiping cloth 19, which not only increases the friction cleaning effect of the wiping cloth 19 on the outer wall of the composite tape 14, but also reduces the consumption of the mixture of alcohol and grease cleaner, preventing excessive mixture of alcohol and grease cleaner from adhering to the outer wall of the wiping cloth 19 and forming water droplets, which would affect the detection effect of the composite tape 14. The outer wall of the friction roller 18, the inner wall of the wiping cloth 19, and both ends of the wiping cloth 19 are provided with corresponding first and second Velcro straps. Based on the matching arrangement between the Velcro straps, the staff can easily and quickly disassemble and replace the wiping cloth 19 to ensure the continuous and effective cleaning work and reduce maintenance and time costs. It should be noted that the outer wall of the wiping cloth 19 is provided with anti-slip texture, which can increase the friction effect between the wiping cloth 19 and the composite tape 14. On the one hand, it improves the cleaning effect of the wiping cloth 19 on the outer wall of the composite tape 14, and on the other hand, it can effectively drive the friction roller 18 and the drive shaft 20 to rotate.

[0026] This invention also discloses a detection method for a novel conductive and thermally conductive material defect detection device with a layered structure, the method comprising the following steps: S1: First, connect the composite tape 14 to the drive tensioning mechanism, and then start the drive tensioning mechanism to perform a tensioning operation on the composite tape 14. This will allow the installed composite tape 14 to be in a tensioned state, so that the composite tape 14 can effectively rub and clean against the wiping cloth 19 on the outer wall of the friction roller 18 in the tensioned state. S2: Turn on the servo motor 10 to rotate and pull the composite tape 14 for winding, so that the composite tape 14 can be inspected by the defect detection mechanism. S3: When performing defect detection on composite tape 14, the outer wall of the tape 14 slides and adheres to the wiping cloth 19, allowing the wiping cloth 19 to rub and clean the outer wall of the composite tape 14 to be tested, removing grease, dust and other contaminants, thus improving the detection effect of the defect detection instrument 3 on the outer wall of the composite tape 14. S4: When rubbing and cleaning the outer wall of the composite tape 14, the wiping cloth 19 can be wetted according to the action of the wetting and cleaning mechanism. The wetted wiping cloth 19 increases the cleaning effect of rubbing and cleaning the outer wall of the composite tape 14. The mixture of alcohol and grease cleaner can effectively dissolve grease, dust and other pollutants. It is highly volatile and leaves little residue, which makes it easy to rub and clean the outer surface of the composite tape 14.
