The full name of geomembrane is "high density polyethylene", with excellent property of environmental stress cracking resistance, low temperature resistance, aging resistance, corrosion resistance, larger using temperature range(-60--+60) and longer service life for 50 years. It is widely used in anti-seepage projects such as landfill of life waste,solid landfill, sewage treatment plant, artificial lake, and tailings treatment.
The main mechanism of geomembrane construction site is to use imperviousness of plastic film to cut off earth dam leakage passage, and bear hydraulic?pressure and adapt to the deformation of the dam with greater tensile strength and elongation; and non-woven fabric is also a macromolecule staple fibre chemical material. The main mechanism of geomembrane construction site is to use imperviousness of plastic film to cut off earth dam leakage passage, and bear hydraulic pressure and adapt to the deformation of the dam with greater tensile strength and elongation; and non-woven fabrics is also a kind of macromolecule staple fibre chemical material, formed by needle punching or hot sticking. It has high tensile strength and extensibility, the combination with plastic film not only increases the tensile strength and puncture resistance of plastic film; and as a result of the rough surface of non-woven fabrics, it increases friction coefficient of contact surface, which is conducive to the stability of composite geomembrane and protective layers. At the same time, they have good corrosion resistance to bacteria and chemical action, erosion resistance to acid, alkali, and salt , and long service when keeping out of the sun.
