Waterproof reliability evaluation of polymer wet laid waterproof roll based on multi factor fuzzy

摘要

In order to accurately evaluate the waterproof performance of polymer wet laid waterproofing membrane, a new reliability evaluation method of polymer wet laid waterproofing roll based on multi factor fuzzy is proposed in this paper. Firstly, sample specimens for waterproof reliability evaluation are prepared. Secondly, the evaluation index system of waterproof reliability of polymer wet laid waterproofing membrane is constructed, and the parameters of the evaluation index are calculated. Finally, according to the fuzzy transformation matrix, a multi factor fuzzy comprehensive evaluation vector is constructed. According to the normalised result of the evaluation vector, the waterproof reliability score is calculated. Refer to different waterproof reliability evaluation standards to complete waterproof reliability evaluation. The experimental results show that the highest accuracy of waterproof reliability evaluation of this method is 99%, and the longest time for waterproof reliability evaluation is less than 0.5 h.
