Geomembrane mechanism

Its 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; And non-woven fabric is also a polymer short fiber chemical material that is formed through needle punching or hot bonding, with high tensile strength and elongation. When combined with plastic film, it not only increases the tensile strength and puncture resistance of plastic film, but also increases the friction coefficient of the contact surface due to the rough surface of non-woven fabric, which is conducive to the stability of composite geomembrane and protective layer. At the same time, they have good corrosion resistance to bacteria and chemical reactions, are not afraid of acid, alkali, and salt erosion, and have a long service life when used in a dark environment.
