Description

Technical Field

[0001] The present invention relates to the technical field of sealing material performance detection, in particular to a new green building material detection device for construction. Background Art

[0002] In the field of green buildings, the airtightness of sealing materials is a key factor affecting the building's energy-saving effect, waterproof and anti-seepage performance, and indoor environmental stability. Its quality is directly related to the realization of the "low energy consumption and high reliability" goals of green buildings. Therefore, accurate airtightness testing of sealing materials is crucial. However, existing testing devices for building sealing materials have obvious shortcomings in practical applications: First, they lack an effective centering positioning mechanism, which makes it easy for the sealing material to be offset when placed manually, resulting in a loose fit between the material and the sealing surface of the test cavity, causing "false leaks" and interfering with the accuracy of the test results. Second, they can only determine whether the airtightness is qualified through single air pressure monitoring, and cannot distinguish whether the leak is due to the airtightness of the material itself or hidden cracks or defects within the material. Under conventional test pressure, hidden defects are easy to close and difficult to identify, making it impossible to eliminate their interference with the test results. Third, the holding mechanism is mostly a single plane holding mechanism, with a single force mode and uneven holding force distribution. Although some devices have a top pressure function, they cannot flexibly adjust the top pressure position and range, making it difficult to fully simulate the force scenarios in the actual application of sealing materials. The detection coverage of different areas of the material is low, and it is impossible to fully evaluate the material performance. Fourth, the degree of automation is low. Positioning, holding, data judgment and other links rely on manual operation, resulting in low detection efficiency and difficulty in adapting to the green building industry's demand for batch testing of sealing materials. These problems make it difficult for existing detection devices to meet the high-precision and high-reliability detection requirements of new green building materials. Summary of the Invention
