The mechanism of geo-membrane

Jul 25, 2017

The main mechanism is to use plastic film impervious water leakage channel, with its larger tensile strength and elongation to withstand water pressure and adapt to the deformation of the dam; Nonwoven fabric is also a polymer staple fiber chemical material, through acupuncture or hot-bonding, with high tensile strength and extensibility, it is combined with plastic film, not only increase the tensile strength and puncture resistance of plastic film, but also because of the surface roughness of non-woven fabric, increasing the friction coefficient of contact surface, is conducive to the stability of composite geomembrane and protective layer. At the same time, they have a good corrosion resistance to bacteria and chemical action, not afraid of acid, alkali, salt erosion, in the case of light use, long life.
