The useful life of geomembrane problem, mainly by the loss of impermeable impermeable plastic film whether action may be, according to the Soviet national standard practical Geomembrane, hydraulic polyethylene with a thickness of 0.2m plus stabilizer film, working life under conditions of water up to 40 to 50 years, working in conditions of life under water 30 to 40 years. Therefore, the useful life of geomembrane sufficient to meet the requirements of the useful life of the dam seepage. HDPE HDPE composite membrane is also known as high-density polyethylene film, HDPE geomembrane, HDPE impermeable membrane, HDPE membrane is a membrane made of plastic HDPE, its HDPE is a high crystallinity, non-polar thermoplastic resin. Original state of HDPE Geomembrane wholesale milky white appearance in thin cross-section was a certain degree of translucent. PE has excellent resistance to most of the characteristics of living and industrial chemicals. Certain types of chemicals will undergo chemical corrosion, such as corrosive oxidizer (nitric acid) Geomembrane manufacturers, aromatics (xylene) and halogenated hydrocarbons (carbon tetrachloride). HDPE geomembrane full name of "high-density polyethylene geomembrane", with excellent resistance to environmental stress cracking resistance, low temperature resistance, aging resistance, corrosion resistance, as well as a large temperature range (-60 - +60) and longer The service life of 50 years, is widely used in solid waste landfill seepage, solid waste landfill seepage, seepage of sewage treatment plants, artificial lake seepage, tailings seepage treatment works.
