Description
Technical Field

[0002] Building boards are flat, rectangular panels of standard size used for wall, ceiling, floor, and furniture components. Waterproofing is a key characteristic of building boards, protecting them from moisture, steam, and other harmful gases and liquids. They also need to be able to withstand water ingress in the event of accidental or unusual immersion.
[0003] Testing the waterproof performance of a sheet material requires processing the sheet material into a sample and then subjecting it to a waterproof test. Existing techniques typically rely on conventional spraying or immersion to determine the appropriate results. However, in practice, numerous factors influence the waterproof performance of a sheet material, such as water temperature, water volume, the presence of additives, and differences in dynamic and static water flow. This single testing method cannot yield accurate data and requires further improvement. Utility Model Content

[0011] The advantages of this utility model compared with the prior art are:

Compared with the other one with smooth water output, it is possible to observe the effects of different water volumes and flow rates on the plate specimens and the waterproofing effect. On this basis, the water in both water storage tanks can be heated, so that more variables can be obtained by free combination, such as hot water with low flow rate, normal temperature water with high flow rate, hot water with high flow rate, etc., making the test results more convincing.
[0013] 2. The effect of dripping or flowing water on the water resistance of the sample can be observed by discharging water through the outlet pipe. The effect of immersing the sample on the water resistance can be obtained by accumulating water and letting it stand, thereby increasing the influencing factors and variables.
[0014] 3. During the experiment, the sample can be set up and fixed, and the lower bottom part is suspended in the air, so that double-sided results can be obtained during immersion. At the same time, the stability is also improved, and the sample is not easily displaced when impacted by water flow. BRIEF DESCRIPTION OF THE DRAWINGS
