Oilfield foundation anti-seepage membrane-油田基础防渗膜

     The anti-seepage film is a composite material made of polyethylene film as the substrate and geotextile, and its anti-seepage performance mainly depends on the polyethylene film. The PE film used for Dongfang anti-seepage membrane mainly includes polyethylene and EVA (ethylene/vinyl acetate copolymer), which are polymer chemical flexible materials with small specific gravity, strong elongation, high adaptability to deformation, corrosion resistance, low temperature resistance, and good frost resistance. The main mechanism is to isolate the leakage channel of the earth dam with the impermeability of plastic film, and to withstand water pressure and adapt to dam deformation with its large tensile strength and elongation.
