Supply Shandong geomembrane manufacturers

Geomembrane with impermeable plastic film as a substrate, and non-woven geotextile composite made of impermeable material, its performance depends on impervious impermeable plastic film performance. At present, the application of impermeable plastic film at home and abroad, mainly polyvinyl chloride (PVC) and polyethylene (PE), EVA (ethylene / vinyl acetate copolymer), tunneling applications as well as design use ECB (ethylene-vinyl acetate modified bitumen blend geomembrane), which is a flexible material polymer chemistry, the proportion of small, strong extension, the ability to adapt to high deformation, corrosion resistance, low temperature, frost performance. Geomembrane construction site and its main mechanism of the non-permeable plastic film is cut off earth leakage passage, with its greater tensile strength and elongation to withstand water pressure and adapt to dam deformation; and non-woven is a high molecular staple fiber chemical materials, through needle stick or hot forming, high tensile strength and elongation, combined with plastic film after it, not only increases the tensile strength and puncture resistance of the plastic film, and because no woven fabric surface roughness, increases the contact surface of the friction coefficient, is conducive to protective layer of geomembrane and stability of. At the same time, they have good bacteria and chemical resistance to aggressive, not afraid of acid, alkali, salt erosion, use in the dark, long service life.
