Seepage control with plastic geotextile film as seepage control base material, they are a flexible polymer chemistry mateeial, a proportion of small, extensibility, styong ability to adapt to the deformation, high. Corrosion resistance, low temperature
esistance, good frost resisrance. And non-woven also is a kind of high poiymer materials, chemical short fiber by acupuncture or hot sticky forming, has high tensile strength and extensibility, it and plastic film, not only increases with the plastic film tensile strength and resistance to puncture ability, and because of non-woven surface coarse, increase the contact surfaces of the friction coefficient, be helpful for composite geomembrane and the stability of the protective layer . At the same time, they to the bacteria and chemical function have better resistance to erosion sex, not afraid of acid, alkali, salt of erosion.
