以塑料薄膜為防滲基材，非織造土工防滲材料復合而成的新型材料土工膜的防滲性能主要取決于塑料薄膜的防滲性能。目前，國內外使用的防滲塑料薄膜，最早有聚氯乙烯(PVC)和聚乙烯(PE)、乙烯(EVA)(乙烯/醋酸乙烯共聚物)。 </p> <p> 其主要機理是土壩滲漏通道塑料薄膜的不透水性，以其較大的抗拉強度和伸長率來承受水壓和西氣壩體的變形;和無紡布是一種高分子化學短纖維材料,通過針刺或熱成形,具有較高的抗拉強度和可擴展性,它與塑料薄膜結合,不僅增加了塑料薄膜的抗拉強度和抗穿刺能力,而且由于無紡布表面粗糙,增大了接觸面的摩擦系數,有利于復合土工膜和防護層。合在一起，它們具有良好的耐細菌腐蝕和化學作用，不怕酸、堿、鹽的腐蝕，在避光的情況下，使用壽命長。 </p> <p> 以塑料薄膜為防滲基材的土工膜，是巖土防滲材料的非織造復合材料，其防滲性能主要取決于塑料薄膜的防滲性能。在國內外，采用抗滲透塑料薄膜，首先是聚氯乙烯(PVC)、聚乙烯(PE)、乙烯/醋酸乙烯共聚物(EVA)，它們是一種高分子化學柔性材料，比重小，延展性強，習慣變形能力高，耐腐蝕、耐低溫、耐冷凍。 </p> <p> 地磚的應用主要取決于地磚的塑料薄膜是否失去了防滲和防水的功能。根據蘇聯國家標準，水工工程用的0.2m穩定劑聚乙烯薄膜，在清水條件下可達40~50年，污水條件下可達30~40年。因此，復合土工膜的使用壽命足以滿足大壩防滲的要求。 </p> <p align="center"> <img onload="resize(this,700)" alt="土工膜的運用年限問題"

以塑料薄膜為防滲基材，非織造土工防滲材料復合而成的新型材料土工膜的防滲性能主要取決于塑料薄膜的防滲性能。目前，國內外使用的防滲塑料薄膜，最早有聚氯乙烯(PVC)和聚乙烯(PE)、乙烯(EVA)(乙烯/醋酸乙烯共聚物)。 </p> <p> 其主要機理是土壩滲漏通道塑料薄膜的不透水性，以其較大的抗拉強度和伸長率來承受水壓和西氣壩體的變形;和無紡布是一種高分子化學短纖維材料,通過針刺或熱成形,具有較高的抗拉強度和可擴展性,它與塑料薄膜結合,不僅增加了塑料薄膜的抗拉強度和抗穿刺能力,而且由于無紡布表面粗糙,增大了接觸面的摩擦系數,有利于復合土工膜和防護層。合在一起，它們具有良好的耐細菌腐蝕和化學作用，不怕酸、堿、鹽的腐蝕，在避光的情況下，使用壽命長。 </p> <p> 以塑料薄膜為防滲基材的土工膜，是巖土防滲材料的非織造復合材料，其防滲性能主要取決于塑料薄膜的防滲性能。在國內外，采用抗滲透塑料薄膜，首先是聚氯乙烯(PVC)、聚乙烯(PE)、乙烯/醋酸乙烯共聚物(EVA)，它們是一種高分子化學柔性材料，比重小，延展性強，習慣變形能力高，耐腐蝕、耐低溫、耐冷凍。 </p> <p> 地磚的應用主要取決于地磚的塑料薄膜是否失去了防滲和防水的功能。根據蘇聯國家標準，水工工程用的0.2m穩定劑聚乙烯薄膜，在清水條件下可達40~50年，污水條件下可達30~40年。因此，復合土工膜的使用壽命足以滿足大壩防滲的要求。 </p> <p align="center"> <img onload="resize(this,700)" alt="土工膜的運用年限問題"
