[0028] The core of this application is to provide a device for testing the wet tack of wallpaper adhesives, so as to facilitate the testing of the wet tack performance of wallpaper adhesives.
[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0030] Wallpaper adhesive is an adhesive used to paste wallpaper. Its main function is to ensure that the wallpaper can be firmly adhered to the wall or ceiling, and to maintain the flatness and appearance of the wallpaper during use. It is a widely used building decoration material. Wet tack is a very important performance indicator of wallpaper adhesive, which reflects the adhesive performance of the wallpaper adhesive in a humid environment.
[0031] JC / T 548-2016 "Wallpaper Adhesives" discloses a test method for the wet tack of wallpaper adhesives. The specific steps are as follows: First, place the test specimen 020 for 4 minutes, then peel off the adhesive surface and quickly attach the adhesive surface to an upright glass plate 010. Figure 1As shown, ensure that edge AA of specimen 020 is positioned above glass plate 010, and edge AD is perpendicular. Use a paint brush to smooth specimen 020 downwards, removing air bubbles and ensuring a tight bond between specimen 020 and glass plate 010. Figure 2 As shown, after a 1-minute pause, carefully pull specimen 020 from line AA to line BB at a constant speed of approximately 20 mm / s. Release specimen 020 and, after a 30-second pause, measure and record the downward displacement of the mark line BB using calipers, accurate to 1 mm. Although JC / T 548-2016 "Wallpaper Adhesives" discloses the wet tack test method for wallpaper adhesives, it does not disclose the specific apparatus for the wet tack test.
[0032] Therefore, such as Figure 3 As shown in the figure, this application discloses a device for testing the wet adhesion of wallpaper adhesive, including a substrate 10, a fixed frame 20, and a moving component 30. The fixed frame 20 can keep the substrate 10 in an upright state and can be fixed or moved as needed to facilitate wet adhesion testing of the test specimen in different locations and ensure that the test data of the test specimen is stable and reliable.
[0033] The following will combine Figures 3 to 5 The present application provides a detailed explanation and description of the device for detecting the wet tack of wallpaper adhesives disclosed in the embodiments.
[0034] Among them, such as Figure 3 As shown, the fixed frame 20 can form a mounting cavity 21 to accommodate the substrate 10, and the substrate 10 can be detachably installed in the mounting cavity 21 so that the substrate 10 can stand upright on a supporting surface such as the ground, thereby placing the test piece for testing the wet tack of the wallpaper adhesive. Meanwhile, the moving component 30 can be disposed on the fixed frame 20, thereby moving the testing device 100. It can be fixed or moved as needed to facilitate wet tack testing of the test piece in different locations, ensuring stable and reliable test data.
[0035] In some embodiments, the substrate 10 may be a glass plate, and the glass plate may be made of tempered glass to prevent the glass plate from breaking and injuring the inspection personnel. The substrate 10 may have a length of 1000 mm, a width of 1000 mm, and a thickness of 10 mm to 19 mm. Of course, the substrate 10 may also be made of other smooth, non-porous, and flat materials.
[0036] In some embodiments, the substrate 10 may be provided with multiple scales 11 perpendicular to the supporting surface such as the ground. That is, two, three or more scales 11 may be used, and each scale 11 may be arranged in parallel, so that multiple test pieces can be simultaneously attached to one side of the scales 11 on the substrate 10 perpendicular to the supporting surface such as the ground, so as to roughly detect the wet adhesion of multiple test pieces. It should be noted that the accurate data of the wet adhesion of the test pieces must be detected by vernier calipers.
[0037] In some embodiments, such as Figure 3 As shown, the fixing frame 20 can be a rectangular frame structure made of stainless steel, and the frame edge of the fixing frame 20 forms a mounting cavity 21. The substrate 10 is detachably installed in the mounting cavity 21 of the fixing frame 20, so that the fixing frame 20 can support the substrate 10. At the same time, by detachably installing the substrate 10 in the mounting cavity 21 of the fixing frame 20, the substrate 10 can be replaced.
[0038] In some embodiments, such as Figure 3 and Figure 4 As shown, the detection device 100 may also include at least two fixing members 40, that is, two, three or more fixing members 40 may be used, and any two sides of the substrate 10 may be fixed to the fixing frame 20 by fixing members 40 respectively, so as to realize the installation and fixing of the substrate 10 and prevent the substrate 10 from being dislodged from the mounting cavity 21 of the fixing frame 20.
[0039] In some embodiments, the fastener 40 can fix two adjacent sides of the substrate 10 to the fixing frame 20 to achieve the installation and fixation of the substrate 10. The fastener 40 can also fix two opposite sides of the substrate 10 to the fixing frame 20, that is, the fastener 40 can fix the top and bottom of the substrate 10 to the fixing frame 20, or the fastener 40 can fix the left and right sides of the substrate 10 to the fixing frame 20 to achieve the installation and fixation of the substrate 10. Of course, the fastener 40 can also fix all sides of the substrate 10 to the fixing frame 20 or fix the corners of the substrate 10 to the fixing frame 20 to achieve the installation and fixation of the substrate 10.
[0040] In some embodiments, such as Figure 3 and Figure 4 As shown, two fasteners 40 can be used, and the two fasteners 40 are respectively fixed on the two sides of the substrate 10 perpendicular to the ground or other supporting surfaces. That is, the fasteners 40 can fix the left and right sides of the substrate 10 to the fixing frame 20 to realize the installation and fixing of the substrate 10.
[0041] In some embodiments, such as Figure 3 and Figure 4As shown, the fastener 40 may include at least two pressure plates 41, and the two pressure plates 41 can respectively press the two surfaces of the substrate 10 to install and fix the substrate 10 in the mounting cavity 21 of the fixing frame 20. At least one pressure plate 41 of a surface can be connected to the fixing frame 20 by fasteners 42 such as bolts. That is, one pressure plate 41 of one surface can be connected to the fixing frame 20 by fasteners 42 such as bolts, while the pressure plate 41 of the other surface can be directly fixed to the fixing frame 20, so that the substrate 10 can be replaced by removing the fasteners 42 such as bolts. Alternatively, both pressure plates 41 of both surfaces can be connected to the fixing frame 20 by fasteners 42 such as bolts, so that the substrate 10 can be replaced by removing the fasteners 42 of either surface.
[0042] In some embodiments, such as Figure 3 As shown, each surface of the substrate 10 may have one pressure plate 41, and the pressure plate 41 extends from the top of the substrate 10 to the bottom of the substrate 10, while as... Figure 3 and Figure 5 As shown, multiple fasteners 42, such as bolts, can be spaced apart along the extending direction of the pressure plate 41 to fix the pressure plate 41 to the frame of the fixing frame 20, thereby achieving the pressing of the substrate 10. Of course, two, three, or more pressure plates 41 can also be spaced apart along the direction of the substrate 10 perpendicular to the ground or other supporting surfaces, and each pressure plate 41 can be fixed to the frame of the fixing frame 20 by one or more fasteners 42, such as bolts, thereby achieving the pressing of the substrate 10.
[0043] It should be noted that when there is one pressure plate 41 on each side of the substrate 10, the length of the pressure plate 41 can be less than the distance between the top and bottom edges of the substrate 10, and the pressure plate 41 can be located at the middle position between the top and bottom edges of the substrate 10 to ensure the reliability of the substrate 10 fixation. Of course, one pressure plate 41 can be used on one side of the substrate 10, and multiple pressure plates 41 can be used on another side to achieve the pressing of the substrate 10.
[0044] In some embodiments, the pressure plate 41 may be made of stainless steel. For example... Figure 4 As shown, the pressure plate 41 can adopt an L-shaped structure, and one end of the pressure plate 41 can be connected to the fixed frame 20, while the other end of the pressure plate 41 abuts against the substrate 10. Specifically, one end of the pressure plate 41 located on one side of the substrate 10 can be welded to the inner side of the frame of the fixed frame 20, while the other end can support the substrate 10. Simultaneously, one end of the pressure plate 41 located on the other side of the substrate 10 can be fixed to the inner side of the frame of the fixed frame 20 using fasteners such as bolts 42, while the other end abuts against the substrate 10. This allows the substrate 10 to be clamped between the two pressure plates 41, thus achieving the installation and fixation of the substrate 10, while also facilitating the disassembly and replacement of the substrate 10.
[0045] In some embodiments, such as Figures 3 to 5 As shown, the movable component 30 may include a support frame 31 and movable wheels 32 disposed on the support frame 31, and the support frame 31 may be connected and fixed to the bottom of the fixed frame 20, thereby enabling the detection device 100 to move via the movable wheels 32. Meanwhile, as... Figure 3 and Figure 5 As shown, a brake 321 can be provided on the movable wheel 32 to lock the rotation of the movable wheel 32 and prevent it from moving freely. When the detection device 100 moves to the target position, the brake 321 can be pressed down, preventing the movable wheel 32 from rotating and thus fixing the detection device 100 in the target position. At this time, the wet adhesion test of the test piece can be performed by the detection device 100. When the detection device 100 needs to move, the brake 321 can be lifted, allowing the movable wheel 32 to rotate and thus move the detection device 100. It should be noted that the movable wheel 32 can be a conventional swivel wheel with a brake 321.
[0046] In some embodiments, such as Figure 4 As shown, two support frames 31 can be used, spaced apart, and as... Figure 3 As shown, a reinforcing crossbeam 33 connects the two support frames 31, and at the same time... Figure 5 As shown, each support frame 31 is provided with at least two moving wheels 32, that is, each support frame 31 may have two, three or more moving wheels 32 to ensure the stability of the movement of the detection device 100.
[0047] In some embodiments, such as Figure 5 As shown, the support frame 31 can adopt a T-shaped structure and is welded from stainless steel. The support frame 31 may include a support crossbeam and a support vertical beam perpendicular to the crossbeam. The support vertical beam is connected and fixed to one side of the fixed frame 20 perpendicular to the ground or other support surface, and is located in the middle of the support crossbeam. Both ends of the support crossbeam are connected to casters 32 to ensure the stability of the movement of the detection device 100. A reinforcing crossbeam 33 can be connected between the two support vertical beams to ensure the overall stability of the support frame 31.
[0048] In some embodiments, such as Figure 5As shown, to improve the strength of the support frame 31, the support frame 31 may also include at least one diagonal brace 34. That is, each support frame 31 may use one diagonal brace 34, and the diagonal braces 34 of the two support frames 31 are staggered. One end of the diagonal brace 34 can be connected to the side of the support beam away from the moving wheel 32, and the other end of the diagonal brace 34 can be connected to the support vertical beam to improve the lateral stiffness of the support frame 31. Of course, each support frame 31 may also use two diagonal braces 34, and one end of each diagonal brace 34 can be connected to the side of the support beam away from the moving wheel 32, and the other end of the diagonal brace 34 can be connected to the support vertical beam, thereby forming a triangular support system to improve the stability and strength of the support frame 31.
[0049] The wet adhesion testing device 100 for wallpaper adhesive disclosed in this application involves detachably mounting a substrate 10 to the mounting cavity 21 of a fixed frame 20, allowing the substrate 10 to stand upright on a supporting surface such as the ground. This allows test specimens to be placed on the substrate 10 for wet adhesion testing. Furthermore, the testing device 100 can be moved via a moving component 30, facilitating wet adhesion testing of test specimens in different locations.
[0050] The wet adhesion testing device 100 for wallpaper adhesive disclosed in this application embodiment can keep the substrate 10 upright by means of the fixed frame 20, and can be fixed or moved as needed to facilitate wet adhesion testing of the test piece in different places and ensure that the test data of the test piece is stable and reliable.
