The function of the geotextile geomembrane is to block the leakage channel of the earth dam with the impermeability of the plastic film, to withstand the water pressure and adapt to the deformation of the dam body with its large tensile strength and elongation, and the non-woven fabric is also a kind of polymer Short fiber chemical materials, formed by needle punching or thermal bonding, have high tensile strength and elongation.
It is a kind of anti-seepage and moisture-proof waterproof building material. Its anti-seepage performance mainly depends on the anti-seepage performance of the plastic film. Geomembrane is blow molded by adding a certain proportion of carbon black masterbatch, anti-aging agent, antioxidant, ultraviolet absorber, stabilizer, etc. to polyethylene resin. It is used to build warehouses, dams, cofferdams, canals, and artificial lakes. , reservoirs and other water conservancy projects.
