Product variety: one cloth one film, two cloth one film, multi-bubble film and so on. Product specifications: unit area quality 200-1600g/m2, film thickness 0.1-1.5mm, strip 0.8-6.6m Product features: integrated anti-seepage drainage, high strength, high friction coefficient, puncture resistance, aging resistance, acid resistance Alkali, prevent soil erosion. Product use: It is mainly used in various reinforced anti-seepage projects such as water conservancy, transportation, tunnel, airport, metallurgical tailings, garbage disposal site and roof anti-seepage. The service life of the composite geomembrane is mainly determined by whether the plastic film loses the anti-seepage and water-proof effect. According to the national standard of the Soviet Union, the polyethylene film with a thickness of 0.2 m and a stabilizer is used under water conditions. The working life can be several decades, and the working years will be reduced under sewage conditions. Therefore, the useful life of the composite geomembrane is sufficient to meet the service life of the dam seepage control requirements.
