Up to now, high-rise buildings have widely used paint finishing technology both on the outside and inside. Paints bring people safety and benefits with their excellent protective and decorative properties.

[0003] China Patent Authorization Announcement No.: CN214201137U, provides a crack resistance detection device for non-expanding fire retardant coatings. This patent uses the action of rollers and wheels. The workpiece is movable on the bottom plate, and the electromagnetic block and the metal block cooperate to transmit its vibration to the workpiece, thereby vibrating the surface of the workpiece to facilitate the detection of the seismic resistance of the coating on the workpiece surface. It solves the problem of not being able to detect coating cracking in real time, and the high analysis cost and long detection cycle.

[0004] When the above-mentioned detection device is in use and a vibration test is performed on a workpiece, the vibration frame rotates as a whole. The vibration frame is fixed inside the U-shaped frame by screws. The vibration of the vibration frame will loosen the screws, making it impossible for the bottom of the vibration frame to completely abut against the surface of the workpiece, thereby reducing the accuracy of the non-expanding fire retardant coating performance test results.
