    防滲土工膜以塑料膜做為防水層板材,與無防布復合型而成的土工防水層原材料,新型材料防滲土工膜它的防水層特性關鍵在于塑料膜的防水層特性。世界各國防水層運用的塑料膜

    The anti-seepage geomembrane uses plastic membrane as the waterproof layer plate, and is made of the raw material of the anti-seepage geomembrane which is composed of the composite type of the anti-seepage geomembrane and the non anti-seepage fabric. The key to the waterproof layer characteristics of the new material anti-seepage geomembrane lies in the waterproof layer characteristics of the plastic membrane. Plastic film used for waterproof layer in the world

    關鍵有聚乙烯(PVC)和高壓聚乙烯(PE)、EVA(丁二烯/丙烯酸丁酯預聚物),隧道施工運用中也有設計方案應用ECB(丁二烯甲酸丁二烯瀝青混凝土共混防滲土工膜)的,他們是這種高分子化學軟性原材料,比例較小,延展性較強,融入形變

    The key points are polyethylene (PVC), high-pressure polyethylene (PE), EVA (butadiene / butyl acrylate prepolymer). In the tunnel construction and application, there are also design schemes using ECB (butadiene formate butadiene asphalt concrete blend impermeable geomembrane). They are the polymer chemical soft raw materials with small proportion, strong ductility and deformation integration.
