The composite geomembrane is made of filament geotextile or staple fiber geotextile and PE geomembrane through thermal compounding. It has excellent characteristics of plane drainage and anti-seepage. The composite geomembrane is divided into one cloth and one membrane and two cloths and one membrane, with a width of 4-6m and a weight of 200-1500g/square meter. , Good elongation, large deformation modulus, acid and alkali resistance, corrosion resistance, aging resistance, good anti-seepage performance and so on. It can meet the needs of civil engineering such as anti-seepage, isolation, reinforcement, crack prevention and reinforcement in water conservancy, municipal administration, construction, transportation, subway, tunnel, and engineering construction. Due to the selection of polymer materials and the addition of anti-aging agents in the production process, it can be used in unconventional temperature environments. It is often used for anti-seepage treatment of dams and drainage ditches.
Composite geomembrane properties
The composite geomembrane is mainly divided into: one cloth and one membrane, two cloths and one membrane, and multiple fabrics and multiple membranes. This production process not only maintains the good mechanical properties of the geotextile, but also makes the composite product film thickness uniform, high peel strength, avoids the formation of pores and blisters on the film, and greatly improves the impermeability of the film. The flower treatment increases the friction coefficient of the film, which not only improves the stability of the anti-seepage project, but also facilitates the construction. 1. Use of base fabric The company produces composite geomembrane mainly with needle-punched geotextile as base fabric, and can also produce woven fabric, plastic woven fabric and other composite products according to user requirements. 2. Product Specifications 1. One cloth and two films Base cloth: 100-1000g/m Film thickness: 0.1-1.5mm2. One cloth and one film base cloth: 100-1000g/m Film thickness: 0.1-1.5mm3. Two cloths and one film Base fabric: 80-600g/m Film thickness: 0.2-1.5mm
Product varieties: one cloth and one film, two cloths and one film, multiple cloths and multiple films, etc. Product specifications: mass per unit area 200-1600g/m2, film thickness 0.1-1.5mm, width 0.8-6.6m Product features: integrated with anti-seepage and drainage, high strength, high friction coefficient, puncture resistance, aging resistance, acid resistance Alkali, prevent soil erosion. Product use: Mainly used in various reinforced anti-seepage projects such as water conservancy, transportation, tunnels, airports, metallurgical tailings, garbage disposal sites, and roof anti-seepage. The service life of the composite geomembrane is mainly determined by whether the plastic film loses its anti-seepage and water-repellent effect. According to the Soviet national standard, the polyethylene film with a thickness of 0.2m and stabilizer used for hydraulics is used under the condition of clear water. The working life can reach several decades, and the working life will be reduced under sewage conditions. Therefore, the service life of the composite geomembrane is sufficient to meet the service life of the dam anti-seepage requirements
