HDPE geomembrane (every root layer, waterproof membrane, light mask, moisture-proof membrane film culture, to mold, gas barrier film) impermeable membrane impermeable coefficient --HDPE ordinary waterproof materials can not match the anti-seepage effect, water vapor permeability coefficient K <= 1.0 * 10-13g.cm / ccm2.s.pa. Chemical stability --HDPE impermeable membrane has excellent chemical stability, widely used in sewage treatment, chemical reaction tanks, landfill. 80 kinds of acid and alkali chemical resistance, high temperature resistance, asphalt, oil and tar, acid, alkali, salt and other corrosive media. Anti-aging properties --HDPE impermeable membrane has excellent anti-aging, anti-UV, anti-break capability, can be exposed using the material life of 50--70 years, to provide good material to ensure impervious to the environment. Resistance to plant roots --HDPE impermeable membrane has excellent resistance to puncture ability to resist most of the plant roots. High mechanical strength --HDPE impermeable membrane has good mechanical strength, excellent flexibility and deformation capacity makes it ideal for expansion or contraction of the base surface, can effectively overcome the uneven settlement of the base surface, tensile strength 28MP, elongation at break 700 Good% economic --HDPE impermeable membrane using new technology to improve the anti-seepage effect, but the production process more scientific, speed Jie, product cost less than traditional waterproof material, measured by the actual use of HDPE impermeable membrane project to save costs 50 about%. Construction speed --HDPE impermeable membrane has a high flexibility, a variety of specifications laid forms to meet the requirements of different projects seepage, using hot-melt welding, weld strength, construction convenient and fast. Non-toxic materials, environmental protection --HDPE impermeable membrane materials used are non-toxic and environmentally friendly materials, seepage is a common principle of physical changes, does not produce any harmful substances, it is the best choice for environmental protection, farming, drinking water pool.
