[0002] Camouflage coatings are special coatings used to simulate and deceive enemy reconnaissance methods. These coatings are typically made from materials with special visual effects, simulating the appearance of various natural environments and object surfaces, making them undetectable to the naked eye. Camouflage coatings are widely used in the military field, primarily to protect military equipment and facilities, making them difficult for the enemy to detect. The main characteristics of camouflage coatings are as follows: 1. High Simulation: Camouflage coatings need to imitate the appearance of various natural environments and object surfaces, therefore they usually have strong visual simulation capabilities, making it difficult for the human eye to distinguish between real and fake targets. 2. Anti-interference: To improve the camouflage effect, modern camouflage coatings usually contain multiple anti-interference materials such as radiation-resistant, heat-resistant, and visible light-resistant materials, making it difficult for enemy detectors to detect the target. 3. Maintainability: Camouflage coatings are highly maintainable, and damaged parts can be repaired to a certain extent to maintain the camouflage state. 4. Versatility: Different camouflage coatings need to be developed according to different camouflage targets and scenarios, therefore camouflage coatings have high research and development and production costs. 5. Rapid Upgradability: As enemy detection technologies evolve, camouflage coatings also need constant updates to adapt to new detection methods. my country has extensive research and application experience in the field of camouflage coatings and has successfully developed a variety of high-performance camouflage coatings, providing effective protection for military equipment.

[0003] Paint testing is the process of inspecting the technical specifications of paint products. Here are some common paint testing methods: 1. Appearance inspection: Checking the paint's color, odor, density, viscosity, and other physical properties, as well as for defects such as bubbles and sediment. 2. Color difference inspection: Detecting the color deviation of the paint under different light sources and whether it conforms to the specified color difference range. 3. Weather resistance inspection: Checking the paint's performance under different weather conditions (such as sunlight, rain, cold, etc.), and whether problems such as fading, chalking, and cracking occur. 4. Adhesion inspection: Checking the adhesion between the paint and the surface of the coated object, including whether the coating is uniform and whether it will peel off. 5. Abrasion resistance inspection: Checking whether the paint will experience wear, peeling, blistering, or other problems during use. 6. Corrosion resistance inspection: Checking the paint's resistance to contact with chemicals such as acids, alkalis, and salts. 7. Flame retardancy inspection: Checking the paint's stability under combustion conditions, and whether it will produce dense smoke or toxic gases. 8. Impact resistance inspection: Checking the paint's durability under impact. 9. Rust Resistance Test: This tests the coating's ability to prevent rust when exposed to water or in humid environments. These are some common coating testing methods. Of course, there are other specialized testing methods; the specific method should be selected based on the characteristics of the coating product and its intended use.

[0004] Camouflage coatings are often a combination of multiple pigments sprayed on, but some paint samples are not planar structures, and conventional testing equipment cannot detect them after sampling. Summary of the Invention

[0026] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are used only to explain this disclosure, and should not be construed as limiting this disclosure. Rather, embodiments of this disclosure include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims. Example

[0027] refer to Figures 1-2 This embodiment proposes a friction device for detecting paint wear, used to rub paint samples with a tilted surface, thereby facilitating subsequent detection of friction marks. The friction device for detecting paint wear may include:

[0028] Base 1 can be a horizontally placed flat plate structure used to form a supporting foundation. Support legs are fixed at its four corners to stabilize the friction device. Details will not be elaborated here.

[0029] Support frame 2, mounted on base 1, forms an installation support structure. Support frame 2 can be an L-shaped structure or a gantry structure. While a gantry structure provides stable support, an L-shaped structure avoids operational obstruction and increases operating space.

[0030] The lifting rod 9 is mounted on the support frame 2 in a height-adjustable manner. The lifting rod 9 can be a vertically arranged polygonal prism or cylindrical rod structure, with the polygonal prism structure being preferred. The polygonal prism structure can prevent the lifting rod 9 from rotating during the lifting process, thereby controlling the direction of friction.

[0031] A friction head 10, installed at the bottom of the lifting rod 9, can change its orientation according to the pressure applied by the lifting rod 9, thus adapting to paint samples with different inclines. The friction head 10 may include a ball cavity seat 15, a universal ball 16, and a friction plate 17. The ball cavity seat 15 is fixedly connected to the bottom of the lifting rod 9, which can be welded or screwed. The bottom of the ball cavity seat 15 has a ball cavity into which the universal ball 16 can be rotatably fitted. The specific structure of the universal ball 16 is existing technology and will not be described in detail here. The bottom of the universal ball 16 is fixedly connected to the friction plate 17, which can be a circular or rectangular sheet structure. The lower surface of the friction plate 17 is provided with a friction layer. When the paint surface needs to be tested, the lifting rod 9 applies downward pressure to the friction head 10, and the paint surface provides support force to the friction plate 17, thereby causing the friction plate 17 to make contact with the paint surface. The sample slides, thus completing the friction process. A screw is fixedly connected to the middle of the upper surface of the friction plate 17. A matching screw hole is provided inside the universal ball 16, allowing the screw to fit into the screw hole, thus enabling the assembly and disassembly of the universal ball 16 and the friction plate 17. By placing the screw hole inside the universal ball 16, the internal space of the universal ball 16 can be utilized, thereby reducing the rotation radius of the friction plate 17 and improving its applicability. A notch 18 is provided on the side wall of the ball cavity of the ball cavity seat 15. The ball cavity seat 15 is elastic; when it is necessary to connect and install the ball cavity seat 15 and the universal ball 16, the universal ball 16 can be pressed to open and deform the notch 18, allowing the universal ball 16 to enter the ball cavity of the ball cavity seat 15. The ball cavity seat 15 then returns to its original shape, making installation convenient and quick.

[0032] A gravity counterweight, fixedly connected to the lifting rod 9, is used to apply a quantitative pressure to the lifting rod 9 by using different counterweights. The gravity counterweight may include a counterweight liquid tank 3, an injection port 5, and a drain port 8. The counterweight liquid tank 3 can be a sealed cylindrical structure. The top of the lifting rod 9 can be fixedly connected to the center of the bottom of the counterweight liquid tank 3, thereby ensuring balanced force on the lifting rod 9 and preventing uneven force distribution. The counterweight liquid tank 3 is connected to the injection port 5 and the drain port 8. The injection port 5 can be connected to the top of the counterweight liquid tank 3, facilitating the injection of water into the tank. The drain port 8 is connected to the bottom of the counterweight liquid tank 3. Water can be drained from the counterweight liquid tank 3 through the drain port 8. However, it is not excluded that the counterweight liquid tank 3 must contain water; other liquids can also be injected, but details will not be elaborated here. The injection port 5 can be equipped with a rotary valve or a one-way valve, preferably a one-way valve, allowing water to be directly injected into the counterweight liquid tank 3 through the injection port 5. The drain port 8 can be equipped with a rotary valve; opening the rotary valve allows the liquid inside the counterweight liquid tank 3 to be discharged. An observation window 6 is provided on the side wall of the counterweight liquid tank 3, allowing observation of the liquid level inside. The observation window 6 is engraved with scale lines 7, through which the applied pressure F of the lifting rod 9 can be read. Specifically, the liquid level height inside the counterweight liquid tank 3 can be read through the scale lines 7. Taking the counterweight liquid tank 3 as an example with a cylindrical structure, the pressure on the lifting rod 9... Where F0 is the sum of the weights of the lifting rod 9, the counterweight tank 3, and the friction head 10, h is the height of the liquid level in the counterweight tank 3, and ρ is the density of the liquid; if it is water, its density is 1000 kg / m³. 3 Where g is the acceleration due to gravity, with a value of 9.8 N / kg, and S is the bottom area of ​​the counterweight liquid tank 3; the specific calculation details are not elaborated here. The top of the counterweight liquid tank 3 may have an opening, covered by a lid 4. Closing the lid 4 increases the airtightness of the counterweight liquid tank 3, preventing liquid evaporation and ensuring its gravitational stability. Opening the lid 4 allows for cleaning and repair of the liquid inside the counterweight liquid tank 3. Pressure control is achieved by injecting water into the counterweight liquid tank 3, eliminating the need for applying weights and custom-made weights. It also allows for stepless adjustment, convenient control, low production costs, and quick and easy implementation.

[0033] A sliding platform 11 is slidably placed on the base 1. The sliding platform 11 can be a rectangular plate structure. The sliding platform 11 is used to place paint samples. A clamping fixture 13 is provided on the sliding platform 11. When it is necessary to test the paint sample, the paint sample can be fixed on the sliding platform 11 by the clamping fixture 13. The specific structure of the clamping fixture 13 is prior art and will not be described in detail here. A guide rail 12 is fixedly provided on the upper surface of the base 1. The direction of the guide rail 12 is consistent with the sliding direction of the sliding platform 11. The sliding platform 11 can be slidably placed on the guide rail 12. The specific structure of the guide rail 12 is prior art and will not be described in detail here.

[0034] A sliding push-pull component 14 is mounted on the base 1 and connected to the sliding platform 11. The sliding push-pull component 14 drives the sliding platform 11 to slide linearly. The sliding push-pull component 14 can be a lead screw and a rotating structure. One end of the lead screw is rotatably connected to one end of the sliding platform 11. The sliding push-pull component 14 is nested in the base 1. The rotating structure drives the lead screw to rotate, thereby driving the sliding platform 11 to slide, causing the paint surface of the paint sample on it to slide relative to the friction head 10, thus completing the friction. The sliding push-pull component 14 can also be a combination of a motor and a lead screw, but details are not elaborated here.

[0035] When a paint sample needs to be tested, the paint sample is placed on the sliding platform 11 and then fixed on the sliding platform 11 by the clamping fixture 13. Then, according to the actual pressure requirements of the test, the required volume of water is injected into the counterweight liquid tank 3. Then, the friction head 10 is placed on the upper surface of the paint sample. Under the action of gravity, the friction surface of the friction head 10 makes full contact with the paint surface. The sliding platform 11 is pushed to slide by the sliding push-pull component 14, so that the friction head 10 slides relative to the paint surface, thereby completing the friction.
