Supply Liaoning Ouchi, fish ponds, landscape Lake, waste disposal pool impermeable membrane contact [Li] (182 6481 7103) QQ: {46-37-96-887} geomembrane geotextile look forward to sincere cooperation with you the membrane impermeable plastic film as the substrate, and non-woven geotextile made of impermeable material, its performance depends on impermeable impermeable plastic film performance. At present, the domestic and international application of impermeable plastic film, polyvinyl chloride (PVC) and polyethylene (PE), EVA (ethylene / vinyl acetate copolymer), the tunnel applications designed to use ECB (vinyl acetate ethylene modified the asphalt blend geomembrane), they are a flexible material polymer chemistry, the proportion of small, strong extension, adapt to high deformation, corrosion resistance, low temperature resistance, frost resistance. Geomembrane construction site The main mechanism of the impermeability of the plastic film cut off earth leakage channel, with its greater tensile strength and elongation under pressure and adapt to dam deformation; non-woven is a high- molecular staple fiber chemical materials, acupuncture or hot, sticky forming, high tensile strength and elongation, it is combined with plastic film, not only increases the tensile strength and puncture resistance of plastic film, and because no woven fabric surface roughness increases the coefficient of friction of the contact surface is conducive geomembrane and the stability of the protective layer. The same time, they are good bacteria and chemical erosion resistance, not afraid of acid, alkali, salt erosion in the dark case, long service life. The useful life of synthetic materials in view of the composite geomembrane part of the field observation results in engineering applications with a certain degree of anti-aging ability of its useful life in some countries, certain documents were made more grace the provisions, such as the former Soviet Union BCH07-74 earth-rock dam application polyethylene impermeable structure notified ", polyethylene geomembrane can be used for the useful life of not more than 50 years of building. Linz, Austria polypropylene composite geomembrane geosynthetics long-term traits conclusions "in an article wrote:" polypropylene than 15 years of experience in field applications, their chemical and biological stability; fabric the maximum damage in the construction; no major changes after laying; stability ... can be expected to be more than 100 years.
