Composite geomembrane (composite anti-seepage membrane) tau muab faib ua ib daim ntaub thiab ib daim nyias nyias thiab ob daim ntaub thiab ib daim nyias nyias, nrog rau qhov dav ntawm 4-6m, qhov hnyav ntawm 200-1500g / sq. tensile lub zog, kua muag kuj, thiab tawg. High, cov khoom muaj cov yam ntxwv ntawm lub zog siab, zoo elongation kev ua tau zoo, loj deformation modulus, acid thiab alkali tsis kam, corrosion kuj, aging kuj, thiab zoo impermeability. Nws tuaj yeem ua tau raws li qhov xav tau ntawm kev tsim vaj tsev engineering xws li kev txuag dej, kev tswj hwm hauv nroog, kev tsim kho, kev thauj mus los, subways, tunnels, engineering kev tsim kho, kev tiv thaiv kev tawm tsam, kev sib cais, kev txhawb nqa, thiab kev tiv thaiv kev tawg. Nws yog feem ntau siv los tiv thaiv cov dej ntws tawm ntawm cov kwj dej thiab cov kwj deg, thiab kev kho cov pa phem ntawm cov khib nyiab pov tseg.
