The composite geomembrane
1. Product introduction
Compound geomembrane is by filament geotextile or staple fiber geotextile and PE geomembrane compounded by the heat, has excellent characteristics of surface drainage, seepage control.Composite geomembrane is divided into a cloth a membrane and two cloth film, 4-6 m wide, weighs 200-1500 g/m2, tensile and tearing resistance, bursting physical mechanics performance index is high, the product has high strength, good extension performance, large deformation modulus, resistance to acid and alkali corrosion resistance, ageing resistance, good anti-seepage performance.Can satisfy the water conservancy, municipal, construction, transportation, subway, tunnel, the seepage control engineering construction, separation, reinforcement, anti-cracking reinforcement and other civil engineering needs.Due to the choice of the polymer material and production process to add the aging proof agent, it can be used in the abnormal temperature conditions.Commonly used in dam seepage prevention and drainage ditches, and anti-fouling processing of scrap yard.
