[0002] In the field of material science, anti-fouling coatings have attracted much attention due to their unique self-cleaning and water-repellent properties. These coatings are widely used in various industries such as building facades, automotive surfaces, textiles, and electronic products, aiming to reduce the adhesion of pollutants and improve the durability and aesthetics of materials. Among these properties, water-repellent property is one of the key indicators to measure the performance of anti-fouling coatings, usually evaluated by measuring the contact angle of water droplets on the coating surface.

[0003] Traditionally, to accurately measure the water droplet angle and evaluate the water-repellent ability of anti-fouling coatings, researchers and enterprises often use electron microscopes for observation. With its high resolution and magnification, the electron microscope can clearly capture the fine structure of the water droplet and coating contact interface, thus accurately measuring the contact angle. However, this method, although accurate, has significant limitations.

Secondly, electron microscopes are bulky and complex to operate, requiring professional technicians to operate and maintain, limiting their convenience and flexibility. More importantly, electron microscopes are usually installed in fixed laboratory environments and cannot be easily taken outdoors or production sites for real-time measurement, which is extremely inconvenient for industrial applications that require frequent evaluation of coating performance.

[0026] As Figures 1-5As shown, a simple anti-fouling coating water droplet angle measuring device, including front and rear through lens barrel 6, the lens barrel 6 is integrally formed by front and rear barrel, the convex lens 3 is installed in the front barrel, the concave lens 4 is installed in the rear barrel, the opening position of the front barrel is provided with a plane glass plate 1, the upper half circle position of the plane glass plate is provided with an angle scale, the center position of the angle scale coincides with the axis position of the lens barrel 6, and the opening position of the rear barrel is used for the observer to measure and observe. The opening barrel wall position of the front barrel is uniformly provided with a plurality of illumination LED lamps 2.

[0027] The convex lens 3 in the utility model is located in the front barrel, which plays a role in magnifying the water droplet image. When the water droplet is located on the plane glass plate 1, the convex lens can capture and magnify the image of the water droplet and the coating contact interface, so that the observer can more clearly see the outline of the water droplet. The concave lens 4 is located in the rear barrel, which is used to adjust the magnified image, so that it is more suitable for the visual habit of the observer, and the measurement accuracy is improved.

[0028] The plurality of illumination LED lamps 2 are uniformly arranged at the opening barrel wall position of the front barrel, which provides uniform illumination conditions for the water droplet. This helps to reduce light reflection and shadow, making the outline of the water droplet more clear, and facilitating the observer to measure the angle.

[0029] The observer measures and observes through the opening position of the rear barrel. Due to the magnifying effect of the convex lens and the concave lens, and the illumination of the LED lamp, the observer can clearly see the details of the water droplet and the coating contact interface. For example, Figure 4 、 5 , the included angle of the water droplet is measured as 110° and 60° respectively, and the user can use it conveniently.

The switch controls the illumination LED lamp 2 to illuminate the water droplet on the anti-fouling coating. The observer can conveniently turn on or off the LED lamp through the switch to adapt to different illumination conditions.

[0031] Specifically, as shown in the figure, the front barrel and the rear barrel are both cylindrical structures, and the diameter of the front barrel is greater than that of the rear barrel.

[0032] Specifically, as shown in the figure, the observer moves the lens barrel 6, so that the tangent of the edge of the water droplet coincides with the angle scale of the angle scale, and the included angle of the water droplet is measured. The plane glass plate 1 is made of anti-glare material, and the scale range of the angle scale is 0-180°.

[0033] The upper semicircle position of the plane glass plate 1 is provided with an angle scale, and the center position of the angle scale coincides with the axis position of the lens barrel 6. This enables the observer to measure the water droplet angle of view by moving the lens barrel so that the tangent of the edge of the water droplet coincides with the angle scale of the angle scale, thereby measuring the water droplet angle of view. The scale range of the angle scale is 0-180°, which can meet the needs of different angle measurements. At the same time, the plane glass plate is made of anti-glare material, which reduces the interference of light reflection on the measurement.
