The difference between the geotechnical membrane and the earthwork cloth?

Article :Shandong Shouyue Yue geotechnical materials Co., Ltd. Add time:2016/04/29 PV:

Geotextile, also called geotextiles, it is made of synthetic fiber by acupuncture or the permeability of woven geosynthetic materials. Finished products for cloth, width is commonly 4 to 6 m, length is 50-100 meters. Geotextile divided into woven geotextile and non-woven geotextile. Geotextile has excellent filtration and drainage, isolation, reinforcement, seepage control, protection, light weight, high tensile strength, good permeability, high temperature resistance, freezing resistance, ageing resistance, corrosion resistance.

Geomembrane construction site geomembrane to plastic film as the backing material, seepage control and non-woven composite geotechnical seepage control material, its seepage control performance mainly depends on the seepage properties of plastic film. At present, the main seepage control of the application of plastic film, with polyvinyl chloride (PVC) and polyethylene (PE), EVA (ethylene/vinyl acetate copolymer), they are a kind of flexible polymer chemistry material, the proportion of small, extensibility, adapt to the deformation capacity, high corrosion resistance, good low temperature resistance, frost resistance performance is good. The main mechanism is a plastic film impervious partition earth dam leakage channels, with its larger tensile strength and elongation under pressure and adapt to the deformation of dam body; And non-woven fabric is a kind of high polymer chemical short fiber material, through needle stick or hot forming, has high tensile strength and extensibility, it combines with plastic film, not only increased the tensile strength and puncture resistance of plastic film, and because the non-woven fabric surface is rough, increasing the contact surface friction.
