[0002] Waterproof membrane is a new polymer waterproof material. Its production process requires higher technical requirements than conventional waterproof materials. It can enhance the airtightness and watertightness of buildings and is a healthy and environmentally friendly material. As a key waterproof building material, the membrane's anti-leakage performance is crucial, impacting the overall waterproofness and service life of the board to which it is attached.

[0003] When testing the permeability of waterproof membranes, due to their inherent thinness and lack of support, they are typically attached to a sheet material for a drip or immersion test. Existing techniques, using only drip and immersion tests are quite limited, unable to test the effects of water at different temperatures on membrane performance, or to determine how well the membrane withstands raindrops of varying sizes during outdoor use. Furthermore, existing techniques typically rely on visual inspection to determine if the membrane has penetrated. However, due to the light color of the membrane, this method is not accurate enough and leaves room for improvement. Utility Model Content
