Description

Technical Field

[0001] This utility model belongs to the technical field of testing devices, and more specifically, it relates to a testing device for the impermeability of waterproof coatings. Background Technology

[0002] Against the backdrop of accelerated urbanization and ever-increasing requirements for building quality, waterproof coatings, as core materials ensuring the durability and safety of building structures, directly determine the quality and lifespan of waterproofing projects due to their impermeability. In practical use, the failure of waterproof coatings to resist impermeability can lead to mold growth on walls, structural damage, and even significant economic losses such as the shutdown of utility tunnels. To standardize the assessment of the impermeability of waterproof coatings, it is clearly required to quantitatively test and evaluate the material's impermeability by simulating actual water pressure environments. Therefore, a testing device is needed to facilitate the testing and processing of the impermeability of waterproof coatings.

[0003] Based on existing technology, it has been found that existing waterproof coatings are usually tested by applying water pressure during use. However, since waterproof coatings mainly face instantaneous moisture during actual use, and water pressure testing relies on external intervention, it cannot test the water resistance in actual applications. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model relates to a waterproof coating impermeability testing device. This device solves the problem that waterproof coatings primarily face instantaneous moisture during actual use, while water pressure testing relies on external intervention, making it impossible to test and process the impermeability in practical applications.

[0005] This utility model provides a device for testing the impermeability of waterproof coatings, achieved through the following specific technical means: A waterproof coating impermeability testing device includes: a mounting frame; a top control motor fixedly connected to the top of the mounting frame; a slider slidably connected to the slide rail of the mounting frame; an adjusting screw rotatably connected inside the mounting frame; a fixed support plate slidably connected to the cylindrical rod of the mounting frame; an internal through hole opened in the middle of the fixed support plate; an auxiliary support frame inserted inside the internal through hole; a water-holding plate frame inserted at the top of the fixed support plate; a bottom pressure rubber ring fixedly connected to the bottom of the water-holding plate frame; a top shifting frame slidably connected to the fixed support plate; a top monitoring head fixedly connected to the mounting groove of the top shifting frame; a bottom mounting plate fixedly connected to the mounting frame; and a bottom monitoring head connected to the bottom mounting plate through a threaded hole.

[0006] Preferably, the mounting frame has a slide rail inside; a cylindrical rod is fixedly connected inside the mounting frame; and an inner support block is fixedly connected inside the mounting frame.

[0007] Preferably, the adjusting screw is connected to the top control motor, and the adjusting screw is rotatably connected to the inner support block; the fixed support plate is provided with an insertion hole.

[0008] Preferably, the auxiliary support frame is provided with a water leakage through hole; the bottom of the water placement plate frame is fixedly connected with an insert block for insertion into the insertion hole of the fixed support plate; and the top of the water placement plate frame is fixedly connected with a water storage sleeve.

[0009] Preferably, the bottom pressure rubber ring is disposed on the top of the auxiliary support frame; a rectangular block is provided on the rear side of the top shift frame, and a threaded through hole for cooperating with the adjusting screw is provided on the rectangular block of the top shift frame, and an installation groove is provided on the top shift frame.

[0010] Preferably, the top monitoring head is provided with a monitoring component inside; the top of the bottom mounting plate is provided with a support block, and the support block of the bottom mounting plate is provided with a threaded hole.

[0011] Preferably, the bottom monitoring head is equipped with a monitoring component inside; and a collection cover is fixedly inserted into the outside of the bottom mounting plate.

[0012] The waterproof coating impermeability testing device proposed in this utility model has the following beneficial effects: 1. Both the top and bottom monitoring heads are equipped with professional monitoring components. The top monitoring head can track the changes in the liquid level and permeation rate of the test water in the water plate rack in real time, while the bottom monitoring head can accurately capture the test water signal that penetrates the sample. The two form a closed-loop monitoring process of "before-permeation-permeation" to avoid misjudgment of permeation time caused by traditional single monitoring methods. 2. The fixed support plate, auxiliary support frame, and water-holding plate frame are precisely connected through an "internal through-hole-insert block" structure. Combined with the elastic clamping effect of the bottom pressure ring, the sample coated with waterproof paint can be firmly fixed in the testing area, completely blocking the path of test water leakage from the side of the sample. The water storage sleeve of the water-holding plate frame can be filled with different types of test water as needed to simulate the contact medium of waterproof paint in different application scenarios such as roofs, basements, and bathrooms. The collection cover fixed to the outside of the bottom plate adopts a funnel-shaped structure. The opening diameter covers the entire projection range of the leakage through-hole of the auxiliary support frame and the bottom monitoring head, which can fully collect the test water seeping from the sample. Whether it is a small amount of dripping or a large amount of seepage, it can be completely received by the collection cover, preventing test water from leaking to the outside of the equipment and contaminating the operating table, the ground, or even damaging other laboratory equipment.
