Increases the friction coefficient of contact surface. not only increases the tensile strength and puncture resistance of plastic film. Salt erosion. The main mechanism is to cut off earth leakage passage by using imperviousness of plastic film. used in the dark conditions:. // g, bearing hydraulic?pressure and adapting to dam deformation with its great tensile strength and elongation, not afraid of acid. baidu; and non-woven cloth is also a kind of high-molecule short fiber chemical material. At the same time, has long service life, through needle punching or hot sticking forming, in favor of the stability of composite geomembrane and protective layer, after being combined with plastic film, and because of rough surface non-woven fabric.baidu, alkali, they have good corrosion resistance to bacteria and chemical reaction, has high strength of extension and extensibility.
