What is the geomembrane material?
Function: anti-seepage, isolation Product use: geotechnical dam, rockfill dam, masonry dam and pressure concrete dam; dike, dam front level anti-seepage cover, vertical foundation impervious layer; tailings dam, Roads, highways, railway subgrade; roadbed and other ground salt control; expansive soils; roadbeds, reservoirs (pit, kangang); waste land; subway, basement and tunnel, tunnel seepage lining; And waterproof layer of collapsible loess; roof leakage.
Geomembrane to plastic film as anti-seepage substrate, and non-woven composite made of soil impermeable material, its impermeability depends mainly on the plastic film impermeability. At present, the domestic and international anti-seepage application of plastic film, mainly polyvinyl chloride (PVC) and polyethylene (PE), EVA (ethylene / vinyl acetate copolymer), tunnel applications are designed to use ECB (ethylene vinyl acetate modified Asphalt blended geomembrane), they are a kind of polymer chemical flexible material, the proportion of small, strong extension, adaptable deformation ability, corrosion resistance, low temperature resistance, good frost resistance. I hope I can help you!
Geomembrane to plastic film as anti-seepage substrate, and non-woven composite made of soil impermeable material, new material geomembrane its impermeability depends mainly on the plastic film impermeability. (PVC) and polyethylene (PE), EVA (ethylene / vinyl acetate copolymer), tunnel applications are also designed using ECB (ethylene vinyl acetate modified asphalt), the use of plastic film, Mixed geomembrane), they are a kind of polymer chemical flexible material, the proportion of small, strong extension, adaptable deformation ability, corrosion resistance, low temperature resistance, good frost resistance. Mechanism: The main mechanism is to plastic film impermeable barrier earth dam leakage channel, with its large tensile strength and elongation to withstand water pressure and adapt to dam deformation; and non-woven fabric is also a short polymer Fiber chemical materials, through the needle or hot tack forming, with high tensile strength and extensibility, it is combined with plastic film, not only increased the tensile strength of plastic film and anti-puncture ability, and because of non-woven Surface roughness, increasing the friction coefficient of the contact surface, is conducive to composite geomembrane and protective layer stability. At the same time, they have good resistance to bacteria and chemical resistance, not afraid of acid, alkali, salt erosion, in the case of dark use, long service life.
