Description

TECHNICAL FIELD

[0001] The application relates to the technical field of engineering supervision, and in particular to a wall surface coating adhesion detection device for engineering supervision. BACKGROUND

[0002] Wall surface coating adhesion detection refers to evaluating the bonding strength between the coating and the wall surface substrate through a series of test methods. Adhesion is one of the important indicators of coating quality and directly affects the durability and protection effect of the coating.

[0003] Specific solutions of prior art:

[0004] Visual inspection: observing the color, glossiness and other appearance characteristics of the coating surface with the naked eye to judge the coating quality. The advantage is simple operation and low cost; the disadvantage is strong subjectivity, easy to be affected by environmental factors, and difficult to quantify.

[0005] Knocking and listening method: knocking the wall and listening to the change of sound to judge whether the coating is hollow. The advantage is simple operation and does not require complex equipment; the disadvantage is low accuracy, which depends on the experience and hearing of the detector.

[0006] Ultrasonic detector: using the difference in propagation speed of ultrasonic waves in different media to detect the thickness and adhesion of the coating. The advantage is that non-destructive testing can be realized with high precision; the disadvantage is that the equipment cost is high and the operation is relatively complex, which requires professional training.

[0007] Pulling tester: by applying a vertical upward force to the coating, measuring its maximum bearing force to evaluate the adhesion. The advantage is that the test result is intuitive and reliable; the disadvantage is that the equipment is heavy and not suitable for rapid detection on site, and may cause damage to the coating.

[0008] The existing detection methods either rely too much on human experience and lack objectivity and accuracy, or are expensive and complex to operate, which is not convenient for widespread use on construction sites. Therefore, it is urgent to develop a portable, low-cost and simple wall surface coating adhesion detection device to improve detection efficiency and accuracy. Content of the utility model

[0015] As a preferred embodiment, one end of the gas pipe away from the gas pump is fixedly communicated with the suction disc, and the gas pipe is arranged in the inner wall of the circular tube and the rotating block.

[0016] By adopting the above technical scheme, the gas pump can be driven to inhale, so that the suction disc is attached to the wall surface to be detected, and the device can be stably adsorbed on the wall surface.
