What is filament composite film?

composed of long-fiber geotextile and polyethylene film. Long-fiber geotextiles are usually woven from tough materials such as polypropylene, featuring excellent tensile strength and durability. They can effectively fix soil and reduce the possibility of soil erosion ‌. Polyethylene film, as a waterproof layer, can effectively prevent water leakage ‌. This composite material not only inherits the excellent waterproof performance of geomembrane, but also integrates the reinforcement advantages of long-fiber geotextile, enabling it to demonstrate outstanding performance in various engineering projects ‌. Long-fiber composite membranes are widely used in multiple fields: ‌ water conservancy ‌ : they are used for anti-seepage treatment of reservoirs, rivers, embankments and channels to ensure the anti-seepage effect and extend the service life of the project ‌. Youdaoplaceholder0 environmental protection ‌ : used for anti-pollution treatment in waste sites to prevent the spread of pollution ‌. Youdaoplaceholder0 transportation ‌ : It is used as a seepage prevention layer in road, tunnel and other projects to enhance the stability of the project ‌. Youdaoplaceholder0 garden ‌ : used for anti-seepage and reinforcement of garden landscapes, maintaining soil stability ‌. The construction methods and cost-effectiveness of long-fiber composite films are diverse, which can be in the form of one fabric and one film, two fabrics and one film, etc. It features high strength, good ductility, large deformation modulus, acid and alkali resistance, corrosion resistance and aging resistance, and is suitable for various temperature environments ‌4. Due to the addition of high molecular materials and anti-aging agents, the filament composite film can be used in various temperature environments and is particularly suitable for anti-seepage treatment of DAMS and drainage ditches ‌. In addition, the construction of composite geomembrane is simple, the construction quality is easy to detect, and the project cost is low. It is a highly cost-effective anti-seepage solution ‌.
